WiCKSON AND PACIFIC RUBAL PbESS. ©CI.A273458 PREFACE In view of the very appreciative reception which the public accorded to the first edition of this work and the urgent demand for its reappearance, it is deeply regretted by the writer that the present edition has been so long delayed. It seemed, however, unavoidable. The revision necessary to include later results of experience and obser- vation and extension to fitly include the advancement of certain vegetables in commercial volume and importance and the methods of handling them, largely developed by local study and experiment, have required much attention. In fact, the revision of the work has required a repetition of the same effort which was invoked in its initial prep- aration, and for which the following claim was made in the preface to the First Edition : "There are very good reasons why the task of preparing such a book has been so long delayed. The subject is appalling in its intricacy. Conditions of soil and climate in California are varied to the last degree, and practice must vary with them. No matter how skilful and success- ful a man may be in his particular locality, his experience can only be a safe guide to those who happen to work under similar conditions. For this reason, though there have been admirable local writers on garden practice from the beginning, their writings, no matter how diligently collected and how well printed, would not constitute a suggestive treatise unless the enquirer should analyze the local conditions and practice and translate them into terms of wide applicability. To do this it is necessary that the principles underlying the successful practice should be discerned and the significance of conditions be interpreted. This task could only be discharged by one who has had opportunity for wide collection of data, and for extended personal observation as well, and one for whom labor would be continually lightened by enthusiastic delight in the siTbject itself. All these advantages the writer can frankly claim, but how well they have been employed in this work it is for the reader to judge." In a work of this kind, involving the experience and observation of many individuals during a considerable period of time, it is impossible to render a full account of the writer's indebtedness. Whenever direct use has been made of the experience and methods which others have formulated, an attempt has been made to give defi- nite credit to the source. When such accounts of experi- ence are used without citation of publication credit is in most cases due to the columns of the Pacific Rural Press, a journal which has been the chief medium for publication of information of this kind for the last forty years.

Though California enjoys world-wide fame for fruits it is an interesting fact that the State first won horticultural recognition by achievements in vegetable growing. Gar- den seeds were more easily transported than trees and formed a part of the scant baggage of many gold-seekers. Seeds were also freely sent by home friends or quickly ob- tained on orders to Eastern dealers as soon as the agri- culturists among the argonauts saw their opportunity in the fabulous rates which esculents commanded. Results too were more quickly secured with garden seeds than with fruit trees. Only a few weeks after their planting the grower saw that he was dealing with forcing and de- veloping agencies in climate and soil more effective than any he had known in his old home and he was quite as sur- priesd at his own achievements as his Eastern friends were incredulous of his descriptions of them. They were ready to believe anything about gold, because their conception of a gold country involved its traditional right to be fa- bulous, but such a concession was not to be made to com- mon vegetables. Eastern people knew cabbages and beans and to attribute to them colossal dimensions and to allege that they grew from seed to succotash without a drop of rain was simply coarse lying. It is easy to see why a milder word would be considered inadequate, for the fol- lowing was one of California's first horticultural procla- mations : "On land owned and cultivated by ]\Ir. James Williams, of Santa Cruz, an onion grew to the enormous weight of 21 pounds, and a. turnip was grown which equaled exactly in size the top of a flour barrel. On land owned and cul- 10 CALIFORNIA VEGETABLES. tivated by Thomas Fallen, a cabbage grew which meas- ured, while growing, 13 feet and 6 inches around its body. The weight is not known. A beet grown by Mr. Isaac Brannan, at San Jose, weighed 63 pounds; carrots three feet in length, weighed 40 pounds. At Stockton, a turnip weighed 100 pounds, and at a dinner for 12 persons, of a single potato, larger than the size of an ordinary hat, all partook, leaving at least the half untouched." — Rep. of the Com. of Patents for 1851 : Part II, p. 4. These statements are vouched for by 12 persons whose names are given. To save the respect of their Eastern friends and at the same time to loyally make known the horticultural glory of the laud they had found, the early vegetable growers had recourse to public exhibitions. The first was held in the fall of 1851 in San Francisco. The ex- hibits did not quite equal the verdict of the horticultural jury cited above but they were notable, e. g. : a red beet from San Jose, 28 inches in circumference, weight 47 pounds ; beets two months from seed in San Francisco, six and seven pounds ; cabbage from Mission San Jose seven feet in circumference, weight 56 pounds ; cucumbers 18 inches in length ; onions five, six and seven inches in dia- meter from a product of nearly 70,000 pounds to the acre ; potatoes from Santa Cruz, 125 pounds from the five vines of a single hill and one potato from Santa Clara 13 inches in length, weighing 7i/4 pounds ; pumpkins and squashes from 100 to 140 pounds each. . The demonstrations furnished by such public exhibi- tions, of which there were several in the early years of San Francisco, were accepted at the East, and even such conservative experts as the late Dr. Warder, of Ohio, were led to exclaim, as early as 1852: "truly this is a wonderful country." To fully appreciate the significance of the facts it must be remembered that the varieties were those of nearly half a century ago and the culture was wholly lacking in the intensive arts which are common property of vegetable growers of the present day. The PIONEER VEGETABLES 11 immensity of the specimens and of the crop, wonderful to the grower and incredible to the distant hearer, was simply the exponent of the capacity of a virgin soil, in which fertility had been accumulating for ages, and the forcing power of a climate wholly new to Americans. In later years California has surpassed even these early stan- dards through the employment of higher horticultural skill, as will be described presently, but it was upon the achievements of the vegetable growers at the very begin- ning of the American occupation that California's horti- cultural reputation was established. How the Pioneers Prospered by Vegetable Growing. — It would be easy to collect quite a volume of interesting instances of how success was attained in the early days, but a single experience must suffice. It illustrates both the resources of the pioneers and the country which they found. G. G. Briggs left New York State in April, 1849, and arrived in California in October of the same year, driving an ox team and walking most of the way. He says : "When I arrived in California I saw at once that there were other means of accumulating gold besides digging it from the mines; that miners and all classes would need turnips and cabbage and other products of the soil; that even then many were suffering with scurvy and other dis- eases for the want of fresh vegetable food. The large crops of native grapes on the banks of the Sacramento were proof of the productive capacity of the California soil and climate. Reaching Sacramento, our party of four had no money and no property but our wagon and three yoke of oxen. I could find no work whatever. I got trusted by a storekeeper for a sack of walnuts and sold them to passers by the teacupful and in five days cleared $50. We sold our oxen and with my part of the money I went to San Fran- cisco to buy garden seeds with which to start vegetable growing on a piece of land I had previously seen in the bottom of the Yuba river, near the present site of Marys- 12 CALIFORNIA VEGETABLES. ville. As it was too early in the season to plant, I bought a whale-boat and began freighting goods; and by spring I had accumulated about $3000. The last load freighted by me included a ton of potatoes, which cost me 40c. a pound. My seeds and potatoes were planted in IMarch, 1851, and everything was doing well until cut to the ground by frost on April 19. My potatoes, however, came up again and made a fair crop. I was not to be cheated out of my vegetable crop, and started out again to buy seeds, but could find none, either in Sacramento or in San Francisco. Returning to Sacramento, I chanced upon some watermelon seeds on the boat, and bought the lot for $20. With these I planted five acres, and cleaned up about $5000 dollars for one summer's work. The next year I planted about 26 acres of watermelons, and in the fall I found I had $20,000 for my summer's work." With the money Mr. Briggs returned to New York for his family and brought also, on his return, some fruit trees, and laid the foundation of his subsequent brilliant rec- ord as a pioneer fruit grower. Others followed about the same course and thus vegetable growing became not only the basis of California's horticultural reputation but ac- tually furnished the capital for the ventures which dem- onstrated the possibility of our great fruit industries. Vegetables at the Missions and the Ranches. — The Am- erican pioneers found little at the establishments of the old regime that was instructive or even suggestive. In fact the Spanish conception of the agricultural capacity and adaptability of the country was not only inadequate ; it was erroneous as well. Though the missions had gardens they were almost destitute of gardening as we understand the term and whether the Spanish and IMexican settlers were deterred from vegetable growing by their distaste for any physical exertion, away from the saddle, or by their ignorance of the fitness of the country, is not a ques- tion of much importance in this connection. Hittell says: "Gardening was not attempted except on a very small VEGETABLES ON THE RANCHES 13 scale and only for such vegetables as could be produced with very little labor. Potatoes and turnips were rare and of garden vegetables in general it may be said that until the advent of foreign settlers they were scarcely culti- vated." Bryant, who visited California in 1846 and ex- amined the Los Angeles gardens, saw only onions, pota- toes, red peppers and beans and added that he beli(!ved other vegetables would grow as well as they. Illustrating the inability of the rancheros to understand the wide applicability of the simple horticultural lessons given at the missions, it is related that at the time of the American settlement most of the Spanish families living in different parts of Alameda and Contra Costa had their garden patches near the Mission San Jose. They knew fruit and vegetables would grow there, because they had seen them in the mission gardens and they did not know they would grow elsewhere and had not taken the trouble to find out. Thus the Estudillos of San Leandro had their garden patch at the Mission San Jose and transported Iheir vegetables 15 or 20 miles while right outside the door of their house at San Leandro was the finest garden soil in the world, and they did not know it ! Neither the mission gardeners nor the rancheros had any idea of the capacity of the country for summer crops with- out irrigation and without any adequate conception of the offices of cultivation they could hardly have attained it. Hence, not having the irrigation facilities which were de- veloped at the missions, and not being inclined to any labor by which their own lands could be irrigated, they would naturally go to the water rather than attempt to bring the water to their land for anything more than stock and domestic uses. Almost at sight the American pioneer horticulturists discerned possibilities and adaptations in the soil and climate which their predecessors had not dis- covered during 75 years of occupation. The relations of race to horticultural progress are very interesting. Vicissitudes of Early Vegetable Growing. — Those who 14 CALIFORNIA VEGETABLES. first discerned the fact that it was easier to get gold with the hoe than with the pick, realized market prices as sur- prisingly great as the vegetables they grew. John M. Horner, of Alameda county, is reported to have cleared about $150,000 from his large venture of SOO acres in vege- table growing in 1851, and others gained much more per acre than he, with smaller operations which did not re- quire so much high-priced labor. But the demonstration of their success proved its destruction. Plantations were made out of all proportion to requirements and disastrous overproduction speedily ensued. The second year after the exhibition in San Francisco, to which allusion has been made, there was a collapse. The following account of po- tato growing shows how sharp was the turn in affairs : In 1852 Beard & Horner's potato crop at Alvarado av- eraged 200 sacks (about 12 tons) to the acre, and sold for upwards of $100,000. The following year everybody cul- tivated them. In Pajaro valley 20,000 sacks were one day bet on a horse race. Beard & Horner contracted theirs in advance at 21/20- a pound to San Francisco merchants. Garrison took 1,000,000 pounds, which were never re- moved, but were allowed to rot on the ground. Saunders & Co. purchased a large quantity, which ttiey stowed aAvay in a hulk in the bay. As warm weather came on the pota- toes commenced growing and threatened to burst the ves- sel open. They commenced dumping the potatoes nito the bay, but the harbor master stopped it, and the owners had to pay for their removal to another locality. With the first disaster the charm and spirit of pioneer vegetable growing passed away. There was, of course, quick recovery in values and very profitable business dune, but it was not the same grand affair and it did not accord with the adventurous spirit of the day. Snu\ll growers near the cities and the mining camps did Avell, but there was not dash enough about market gardening for Ameri- cans and it was soon given over to immigrants from the south of Europe and China and has never been recovered. FOREIGN COMPETITION. 15 Field growth of staple vegetables on a large scale has been continued by Americans, but even in this line he has often been obliged to withdraw from competition with Chinese, Portuguese and Italians with their cheaper labor supply and living expenses. Great enterprises in live stock, wheat, wool and fruit afforded opportunities more to the American taste than vegetable growing. The American settler had incomparably more energy and industrial am- bition than his predecessors, the Mexicans, but he shared with them a liking for doing his work in the saddle or on the seat of a riding plow, cultivator or harvester. Within a decade from the date of the American demonstration of the unique fitness of California for vegetable growing there arose occasion for frequent exhortations to Califor- nia farmers to restore the garden to its proper place in farm plan and policy, and yet California farmers neglected to supply their own tables and the proper adornment of their house yards until the ranch lioQie in this land of beauty and grand horticultural opportunities became a by- word for unthrift and desolation. Fortunately there has been such wonderful improvement during the last decade that these epithets no longer apply to California country homes. Competition with Foreigners.^ — One of the difficulties of the present situation is that while the American-born Cali- fornian has decried vegetable growing, the immigrants from southern Europe and eastern Asia have strongly entrenched themselves in it. Now the competition which the American grower has to encounter is depressing and discouraging. And yet the situation is not at all hope- less. The foreigners are not, as a rule, progressive. They are frugal and industrious to an extreme and they under- take a great deal to please their customers with variety as well as low prices. In some points the American com- petitor can learn from them to advantage. But it is quite easy to surpass them in quality by constant effort for im- proved varieties, which they are slow to introduce, and to cheapen production b,y the use of horse labor and im- 16 CALIFORNIA VEGETABLES. proved tools, while they plod along with hand methods and appliances. If the California farmer should put forth the same effort to adapt conditions to ends and to keep himself at the very front in materials and arts of produc- tion in the growing and selling of vegetables that he has employed in the growing and selling of fruit, we should hear far less of the superiority of the foreigner in the vege- table garden. Recent Achievements in Vegetable Growing. — Although California horticulturists as a class are charged with ne- glect of vegetable growing, and though it must be admit- ted that the term horticulture and its derivatives are al- most wholly used in California to signify fruit growing, it is an important fact that we have vegetable growers who hold the country's record for volumes and uniqueness of special products. A new phase of the vegetable growing industry of the State arose with the openings of the over- land railways. The Eastern demand for some kind of vegetables has led to their production of several import- ant vegetable crops in very large volume and has thus given us specialty farming in vegetables somewhat com- parable with our great fruit specialties. Along this line vegetable growing has seemed worthy of American effort and our people have been proud to undertake production by the carload or trainload of the very crops which they would scorn to think of growing by the wagonload. The features of this line of production will appear in connec- tion with the discussion of the special kinds of vegetables which are involved in it. The statistics of vegetable shipment beyond State lines as given by an expert authority for the years specified is as follows : Shipment of Fresh Vegetables by Rail and Sea. — (Car- loads of 10 tons each): 1902, 6130; 1903, 7839; 1904, 4429 ; 1905, 5961 ; 1906, 8982 ; 1907, 4808 ; 1908, 9350 ; 1909, 8978. The grower for shipment is a specialist; he grows but few kinds, and often one kind only, and it becomes nee- THE COMMERCIAL PRODUCT. 17 essary for him to study the particular kind he raises in all its forms, not only as to selection of variety, but to ob- tain the very best strain of that variety. He also has to study very closely the most economical methods of plant- ing, cultivation, harvesting, and marketing. Location in many instances determines what he shall raise. The chief point to consider is to raise that vegetable which succeeds best at the right time for shipment and to select land and location which favors that achievement. Canned Vegetables. — Another form in which our vege- tables are reaching distant markets in considerable quan- tities is the product of the canneries. The following is a statement of the total pack of vegetables in the years stated : California Product of Canned Vegetables. (cases of 24 cans). 1907. 1908. 1909. Asparagus 174,435 238,420 410,965 Beans 74,040 39,765 12,435 Peas 51,565 88,510 104,010 Tomatoes 1,539,310 1,106,875 672,260 Other kinds 102,405 28,315 43,050 Drying vegetables has been pursued in a small way for a number of years. The rapid extension of the mining in- terest in remote parts of the Pacific Coast created a quick demand for dried vegetables and it was thought that they would constitute an important item in distant shipments, but whenever transportation is established the superior succulence of fresh and canned vegetables discounts the dried product. The volume of California vegetable products includes, of course, dry beans, beet sugar, etc., which are mentioned in the chapters relating thereto. Diversity in Garden Practice in California. — It is hardly too much to say that our garden practice is an epitome of all ancient and modern cultural arts, for we have both survival of very old methods and subterfuges and wider 18 CATJFORNIA VEGETABLES. deiiioiislrations of the truth of advjmecd ('oiic('i)tions of cultui-al efficacy than can probably be found in any other State. This is not due to any purpose or design on the part of our people. It is merely their notable resources of adaptalnlity and ingeiniity brought to bear upon the wide range of conditions involved in our combined winter and summer gardening which concentrates in a single common- wealth all the diversity one might encounter if he were a peripatetic gardener with an itinerary extending from Ireland to Algeria. Nor is this remark intended merely as a reference to the natural diversity of the different parts of the State, because success may require more or less distinct methods in summer and in winter in the same region. In short, the California gardener has to know arid- land practice and humid-land practice and call them both into requisition equally or incline toward one or the other as his conditions demand. It takes a man of some depth and breadth to do this, and this is the reason why land owners who have brought skilled horticultural practitioners from abroad to develop their properties have experienced so many disappoint- ments. It requires head as well as handicraft to master the situation, as subsequent chapters will suggest. CHAPTER II. FARMER'S GARDENS IN CALIFORNIA. It has already been admitted that there has been, ever since the development of large farming enterprises was seen to be possible in California, an indisposition on the part of our farmers to engage in vegetable growing. Sev- eral reasons are urged as explanatory of this very wide- spread sentiment and some of them may be cited : First : The proper conduct of a large specialty farm gives no time for gardening — not even for the direction of work upon it — and it is better to buy vegetables than incur the worry of a garden patch. Second: In small specialty farming on a limited acre- age of especially fitted and high priced land, it is not prof- itable to set apart land for vegetables when its yield in the special product may pay several times the cost of purchased vegetables. Third : Success with vegetables in California is very difficult to attain- — especially so in certain parts of the State — and a farmer is more apt to lose than to gain by any venture he may make in that line. Fourth : It is impossible to have a garden without irri- gation water, even on lands which with ordinary rainfall will yield cereals and carry productive deciduous fruit trees if they are given good summer cultivation. How Far Are the Objections Tenable? — It must be granted that there is some force in the demurrer which the California farmer often enters against his indictment for lack of thrift and neglect of opportunities in not under- taking to produce his home supply of fresh, crisp and wholesome vegetables instead of depending upon the stale and Avilted goods of the itinerant vendors. It is perfectly 20 CALIFORNIA VEGETABLES. conceivable that, under certain conditions, the farmer had better buy food supplies rather than produce them, con- sequently the general denunciation of the unthrift of the California farmer, which is often indulged in by those who know little of the local situation and conditions, is really unwarranted. California conditions, both in nature and in farm policy, are so varied that criticisms and upbraid- ings are often misplaced. And yet it is perfectly true that vegetables "should be grown on farms in California much more generally and in far greater variety than they have been hitherto. It is not the intention of the writer to urge this improvement upon sentimental considerations nor to claim, as many seem inclined to do, that it is possible to compass it by the fiat method. Too many of our critics seem to hold that all the farmer has to do is to declare that there shall be a garden and one will spring up around his footsteps with ideal succulence, richness and deliciousness. It will be better to attempt to show that there is an oppor- tunity, providing its requirements be duly met, and that there are really fewer difficulties in the way and greater rewards for prompt and intelligent effort than many of our farmers imagine. And this can be shown without elaborate argument. A more striking demonstration will probably lie in showing to the many the success of the few, in order that they may draw therefrom lessons and ex- hortations for their own incitement and success. This ser- vice will be constantly held in view as this work proceeds. Essentials to Success in Gardening. — There are three re- quisites to success in gardening and they may be arranged in alliteration thus, Will, Water, Work. They also stand in the order of their relative importance in California. Without a strong impulse In the will it is vain to expect work and water to do their best. If the will is born of taste, liking, enthusiasm, the task will be delightful and the results grand in every way. Unless one has some joy in the rich, moist earth as it yields its fragrance to the touch of his tools; unless he can glory in the quick, re- ESSENTIALS TO SUCCESS. 21 sponsive g'l'owth of the plant when his culture suits its nature, and unless he finds pride and satisfaction in the armful of delicious vegetables which he brings each day to his helpmeet, with the dewdrops of the early morning still sparkling upon their foliage, his gardening will never be an easy task though it may be conscientiously and suc- cessfully discharged. But although it is possible to make a good and profitable garden from a sense of duty and though work will reach its due reward even though one can never bring himself to see that the "primal curse" of the race is really its op- portunity, it is a fact that without work there can be no successful gardening in California. Perhaps work is the price of success everywhere ; perhaps the aggregate of muscular effort proportional to the result is less in Cali- fornia than elsewhere but let no one deceive himself that the California garden will make itself. The item of work may be reduced to a minimum by intelligent direction. In- sight and observation will teach just when each act should be performed to secure the richest co-operative response from nature's forces, and to miss this advantage will en- tail a vast amount of unnecessary effort, but the modicum of incisive action must be bestowed. It will appear later, in connection with the discussion of the planting season, that timely work is a prime factor — in fact the pivot upon which the effort may turn from delight to disappointment. California conditions, though exceedingly generous are equally exacting — probably more exacting than those of humid climates. It is clear then that not only is work an essential, but it must be work well directed and main- tained. The third essential is water. By due understand- ing and employment of the characters of the natural grow- ing season and of the soil in each locality, it is possible to produce a great wealth and variety of vegetables in most parts of the State without irrigation. In some parts suc- cession or rotation can be carried through the year by the most intelligent cultivation to prevent evaporation or by 22 CALIFORNIA VEGETABLES. the use of land naturally and continuously moistened by underflow. Still, the far greater area of the State Avill not give satisfactory vegetable supply without additions to rainfall and the irrigated garden should therefore be the end in view in most of our farm i)lanning. Fortunately this is not nearly so difficult to attain as is commonly thought, as Mnll be shown in a later chapter, and if the farm-architect have the will to work, he will not long lack the v/ater to insure the perfection of his desires in his home garden. Possible Exceptions. — These faint suggestions of the re- quirements of success in gardening, even on the narrow, farm plan, may intimate that broadside exhortations to vegetable growing are not wise and shed some light upon the reasonableness of those who claim that they can not profitably or successfully undertake it. Our great specialty farmers are apt to have their heads and hands too full to think of personally mastering gardening practice in a pe- culiar country. The attempts which have been made to transform the ordinary farm hand into a gardener have usually only yielded disappointment, and the professional gardeners who are really worthy of the name find it too easy to acquire enterprises of their own to warrant their wage-earning on the farm basis. It might as well be con- ceded at once that many large farmers will do better to purchase their supplies from some man who has the knowl- edge and the soil and water facilities for successful pro- duction. It is also true that in many cases the small scale specialty farmer, working a small tract of high-priced land for a high-value product, does well to plant his entire holding, except his house site, to this product. But it is also true that other men of this class will find the reservation of a garden area a most profitable proceeding. What each shall do depends upon his personal traits and tastes. But though these exceptions exist and should be consid- ered in any claims that are made in favor of a much wider FARM GARDENS. 23 enlistment of California farmers in gardening for the pro- duction, at least, of home supplies, the fact remains that farm gardens should be multiplied and that, with proper spirit and effort and appreciation of their value, they can be more easily secured than the popular impression among California farmers would indicate. There is a wealth of experience to show that where good timely work is done, under conditions either naturally favorable or rendered favorable by moderate effort or investment, very gratify- ing results have been attained on farms in all parts of California. Benefits of Farm Gardens. — It is trite to build arguments on this theme, but the points can hardly be sharpened by comment. The dietetic benefit of vegetable food in variety has been demonstrated both by individual experience and by the food studies which are now being systematically pursued both in this country and Europe. Working force, thinking force, the quality of success in all lines of human effort, are all promoted by a generous, well-balanced food supply. The hygienic benefit of food, including due amount of the succulent, aromatic, tonic and assimilable characters which are inherent in fresh and well-grown vegetables, is universally recognized by authorities. The truth has par- ticular force in a region of high temperatures like Cali- lornia. The so-called cooling of the blood, the develop- ment of resistance to malaria, the free and healthful op- eration of the various functions of the body, are unques- uionably promoted by vegetable food. The economic benefit of home-grown esculents has been most clearly discerned during the last few years and the result is a gratifying increase of interest in farm garden- ing. More vegetables have been grown recently on Cali- fornia farms than ever before. The low market values of some of our most important special products have given an impetus to diversification of crops which a century of exhortation could not have compassed. California farmers 24 CALIFORNIA VEGETABLES. have recognized as never before that sound farm policy generally requires the home production of most food sup- plies. Those who have endured with least hardship the financial stress of beginning a farm enterprise are those who have had least to buy and not those who had most to sell. Many a farm has been saved from the mortgage by the yield of subsidary products for home use and for ex- change for essential home supplies. In this most import- ant service the vegetable garden has done its full share and has thus commended itself to the attention of many who formerly looked upon the growth of ''garden sass" as a sort of ignoble pothering. The farm garden saves money and makes money if it is given adequate thought and gen- erous effort. This exhortation can be given forceful concreteness by the following actual instance which occurred in one of our warmer coast valleys : "My garden consists of one acre of good river bottom land, and as a matter of course is under good tilth. Be- sides what we used at home and gave away, we sold to our neighbors as follows : "Green onions, $16; cauliflower, $7; spinach, $4; early cabbage, $12 ; squashes, $8 ; green corn, $10.50 ; lettuce, $2.25 ; tomatoes, $18 ; beets, $3 ; turnips, $4. Total, $84.75. "What can be more profitable? Any farmer can do as well if he will only try. How did we do it? I will tell you. Early in November we planted top onions on one- half acre, and on the other half we planted spinach, beets, lettuce, turnips and carrots. Our seed beds were made in December, and as soon as the onions were ready to pull we replaced them with cabbages, pulling our onions with regard to such planting, also making room for a succes- sion of early peas and snap beans, and finally cucumbers. Of the last three articles we sold a good quantity, and the product will raise the total amount produced for the sea- son to over $100." This is not an isolated instance. Any one can do it who GARDEN IN MIXED FARMING. 25 can command the "essentials to success" previously con- sidered, and almost any one can utterly fail of doing it without them. A hint is given of the succession of crops possible in the California garden. There will be much of that hereafter. The social benefit of the farm garden may enter the realm of sentiment but it is none the less true, potent and precious. The farm with a garden is an inexpressibly bet- ter home than without it. The garden wins interest; it dispenses content. It awakens home pride and strength- ens home love. It has actual educational value in that it directly imparts useful lessons in plant growth and re- quirements which are applicable to all other farm opera- tions. It has lessons also to quicken the love of the beau- tiful which, in turn, leads in all phases of home improve- ment and lifts the standard of rural manhood and woman- hood. Of Especial Application to California. — All these bene- fits of the installation of a garden area on the farm should be especially striven for in California because they can be realized here in exceptional measure. The well-planned California garden is evergreen. It admits of succession and rotation within the year, so that a 12 month is the pro- ducing equivalent of twice or thrice its duration in wintry climates. Here the garden does not insist upon intruding its claims just in the "rush of spring work" which is known in lands of more marked seasonal transitions. It is well content to be "ahead of the rush" the whole year round, but it must be admitted that it stubbornly rebels against being behind it. Not only is succession of tender growths made possible by the long frostless term but more than half of the common garden vegetables are so hardy that they maintain growth even through our short frosty season and, wath irrigation on lands which need it, thrive the whole year in the open air. Rich is the endowment which a semi-tropical climate bestows upon the gardener. He who does not avail himself of it for his own comfort and profit, buries his talent in the earth. 26 CALIFORNIA VEGETABLES. The Garden in Mixed Farming. — During the last few years, aside from the greater interest in vegetable grow- ing on the part of the settlers, which has been noted, there has been a decided gain through the efforts of ncAver resi- dents to make their smaller holdings self-supplying and income-yielding, as well, by due attention to vegetable growing. All through the State the interest has quick- ened and the accomplishment has shown that the old idea that only special, narrow areas were suited to garden lo- cations, was a misconception. Instances are ample to show not only that proper practice brings ample success almost everywhere, but such practice, coupled with intelligent planning, yields such variety of delicious esculents as only a semi-tropical climate allows. This is one of the distinc- tive advantages of California and it favors the develop- ment of small farms of mixed husbandry as well as those devoted to specialties. Of course there are limitations and locations should be selected with discrimination for either mixed or special farming. The mixed farm in an ever growing climate makes requirements it is true but it also bestows compensations. As the forces ministering to growth are continuously active, the full use of them be- speaks corresponding activity on the part of man. There must be a determination to make almost every moment tell in some useful effort. There will be play for the sharpest ingenuity in devising means and methods for time-saving and ceaseless study to make the soil bear the burden of the table to the fullest degree. Small farming requires genius, devotion, and a spirit of content. Its work, when one ac- quires or is born with a liking for it, is full of cheer and enjoyment. Its varied nature is itself a charm. The trees, vines, plants, and domestic animals will rise almost to the plane of companionship. Man, wife and children will join in the spirit of the enterprise they are carrying on with united heart and hand, and loye for home will grow and blossom forth as it seldom does in mansions or on princely estates. Thus the modest calling has its compensations. THE HEN IN GARDENING 27 The iufliience of such homes upon the State is most salu- tary. Sound ideas of economy become prevalent; honor and honesty are qualities which win popular approval. Thus, the State becomes really prosperous and sound at the core. The crowning need of California agriculture is to build up enterprises which will stand alone. We have been leaning too long on the shoulders of bankers and commission merchants and commanders of country stores. Without them it is true much that has been done could not have been accomplished, but it is also true that many losing effort which have been vainly put forth would never have been attempted, and those who have made these efforts would be the better for it. Who can tell how many would have attained moderate and comfortable successes if they had started without encumbrance on a modest plan instead of wasting time with big schemes whose whole returns have gone to feed hungry mortgages and interest accounts, until failure has swept from them the property which they proudly hoped to possess. ■But why intrude this homily ? The garden is one of the elements of success in mixed farming. Around it other elements naturally gather. As gleaners and profitable transformers of garden wastes and surpluses into home supplies and garden restoratives, the cow, the pig, and the hen await outside the garden fence. Be sure to keep them there, and the garden will be a liberal contributor to their vigor and productiveness. CHAPTER III. CALIFORNIA CLIMATE AS RELATED TO VEGE- TABLE GROWING. It is not necessary to attempt an elaborate exposition of the characters of the California climate. Such characteri- zation has been made by different authorities from various points of view. It may be claimed in a general way that our climates are as kindly disposed toward vegetable growth as they are towards the development of fruits or the early maturity, thrift and comfort of animals. The ordinary exemption from ground-freezing at any time of the year ; the absence or very rare and localized occur- rence of soil-shifting winds or even of winds to prostrate tall growths ; freedom from wide extremes in temperature ; and only occasionally great changes in atmospheric hu- midity ; adequate heat for rapid growth with a dry, but seldom desiccating air, which prevents much of the fun- gous growth of hot, humid climates and consequently in- sures a grand and healthy leaf-action to the plant ; abun- dant sunshine, but seldom, and then only in few localities, rising to leaf burning; ample moisture either by rainfall or irrigation, or one supplementing the other^ — all these characters and others like them, constitute a climate of exceptional advantage to the vegetable grower. They reduce provisions for protection to a minimum ; a cloud of smoke or a lot of small fires for the frost ; a high fence or a line of trees for the wind, a lath or slight brush cover- ing or the neighborly shadow of a taller growth for the most tender foliage ; frequent cultivation to retain mois- ture in the soil after rain or irrigation, and the garden will go through the year- with ample protection at its weakest COAST VALLEYS. 29 points. And all these are not needed in the same locality ; in fact some localities need none of them except the mois- ture retention which is universal. LOCAL VARIATIONS IN CLIMATE. Although it is possible to grow almost all vegetables everywhere in the State by intelligent selecting the proper time of the year for each, as shown in other chapters, and although few localities have climates so uniform and equable that by providing proper moisture conditions nearly all vegetables can be grown all the year, it is still possible to define regions with somewhat distinctive cli- matic characters bearing upon garden and field growth of edible plants. Coast Valleys — A considerable volume of vegetable products of California is grown in the coast valleys. This term includes both well-defined valleys of greater or less breadth, and stretches of rather flat or gently sloping land, open to ocean influences. It is a region extending the whole length of the State and lying between the high- est elevation of the Coast Range and the ocean. In the upper half of the State it is composed chiefly of well- defined valleys somewhat parallel to the coast, but pro- tected by low ranges which modify and mollify ocean in- fluences, insuring higher temperature and more gentle winds than are found directly on the coast. In the south- ern part of the State the region chiefly consists of broad areas quite open to the ocean but needing no barriers from it because, owing to the trend of the coast, the lower lati- tude and the greater distance south from the source of the prevailing air currents, the ocean influences are them- selves modified before they reach the lands. In all this vast region, then, similar conditions prevail, locally modi- fied, however, enough to create some marked differences in degree, which have been well utilized as the basis of special production. The difference in degree may be speci- fied in this way : Temperature rises and rainfall decreases 30 CALIFORNIA VEGETABLES. as you proceed southward. Take an instance of specializ- ing production : Humboldt, Mendocino and Sonoma coun- ties, coast side, low temperature and large rainfall, known from the earliest times as a great potato country ; San Luis Obispo, Santa Barbara and Ventura counties, coast side, higher temperatures and light rainfall, producing a considerable part of all the beans grown in the State. And yet though these differences thus notably localize production, the whole coast region north and south has this in common ; it has a more equable and lower tempera- ture and a more generous rainfall than the interior valley at its own latitude ; it also has lighter frosts, growing lighter still toward the south until it incloses regions here and there which favoring topography makes practically frostless. Such situations favor all-the-year growth of the tenderest vegetables, and perennial beans and tomato trees are possible. Interior Lowlands. — A region which has recently greatly advanced in importance in vegetable production comprises the lower lands of the interior valleys. They lie along the two great rivers of the northern and central parts of California — the Sacramento and San Joaquin, and their tributaries. These rivers flow from nearly two hundred miles, north and south of their confluence, where they mingle their waters through numerous sloughs until the joint streams pour through a gap in the coast range into San Francisco bay. The same gap which lets out the waters lets in the ocean current of moisture-laden wind and moderates the heat of the entire interior valley, but naturally dispenses most moisture and coolness over the lowlands which lie just in its course as it rushes north- ward and southward to displace the air which is rarified by the sun heat on the interior plains of the great valley. These interior lowlands along the lower stretches of the rivers have then an interior climate modified by the in- trusion from the coast, but this onlj^ acts in full measure during June, July and August. It serves, therefore, as a RIVER LAND VEGETABLES. 31 moderator of heat and drought during that period and supplements the supply of aqueous vapor which rises by evaporation from the immense acreage of tule swamps and shallow lakes which surround the tillable lands of the region. Climatic conditions in this large interior area favor the growth of vegetables and its producing capa- city is beyond any present commercial use which can be made of it. But though it has a temporary coast modi- fication, as has been stated it falls back into interior habits when restraint is removed. It has intervals of hot, dry winds which exclude the coast winds from access to the valley and then intense dry heat calls for ample water supply, which, fortunately, however, is easily applied, because at such season the rivers and sloughs are running full and if seepage is not enough, siphons or flood-gates admit water from the high-running rivers or pumps yield great volumes at little cost. But the interior lowlands have another more grievous trait. As the.y lie low they are the scenes of the latest spring and earliest autumn frosts and their season for tender vegetables is shorter than that of the coast, though with their higher heat and copious moisture their mid-season product of these ten- der crops may out-volume a slower, longer season on the coast. But the earliest and the latest tender vegetables do not come from the interior lowlands. There are interior lowlands of wonderful producing capacity at considerable distances from the confluence of the two rivers just mentioned. For about three hundred miles the river lands extend both northward and south- ward, offering an area of moist or easily-irrigated land of such fertility and extent that it suggests its own ability to produce vegetables for the whole country. At present hardly an appreciable fraction of one per cent of it is employed in production for which it is best fitted. In the future its lower levels will be the Holland and its upper extensions the Nile valley of California. The farther these lowlands lie from the mouths of the rivers the less they re- 32 CALIFORNIA VEGETABLES. ceive of coast influences. This gives the distant lowlands a higher temperature and greater forcing power upon vegetation. The nights are warm as well as the days. Vegetables of prodigious size and acre-crops which tax credulity, are the result of the favoring conditions. But these lands are low and danger of frost makes it necessary to select crops for hardiness during a part of the year. Interior Plains and Foothills. — Above and away from the lowlands of the rivers and their deltas the interior plains stretch far as the eye can reach, and rise, both on the east and west, into the foothills of the Sierra Nevada and the coast ranges. In southern California somewhat similar regions occur as the lands rise from the coast flats to the mesas and foothills of the high, incurved mountain range which encloses the splendid coast region of southern Cali- fornia. The great interior plains of southern California irrigated from the Colorado river and adjacent valleys irrigated from wells constitute a vast vegetable growing district which has recently attained notable development. There are similar climatic conditions prevailing through these vast interior regions both north and south — except that the extreme south has by its latitude and its escape from ocean influence, a frost freedom and spring time heat which enable it to produce the earliest vegetables in the State. In the interior regions the rainfall is light as compared with the coast until the mountain climate is encountered at varying elevations, when it becomes even greater than on the coast. The mean temperature is higher and, except in certain localities, the frosts cover a shorter period and are less severe. Winter growth of vegetables is widely feasible and plants of less hardi- hood than those of the lowlands are usually safe. But the rains cease earlier in the spring and heat and drought make irrigation essential long before it is required nearer the coast. For summer growth of vegetables, except on small areas moistened by underflow from mountain springs or valley cienegas, irrigation must be provided. These FOOTHILLS AND MOUNTAINS. 33 are the regions which were formerly most apt to be con- demned as unfit for vegetable growing, and it is upon such lands that most failures and disappointments occur. It is true that local climatic conditions here need most radical modification by art of man, but it is here also that prompt and timely work and adequate irrigation, wind protection and partial shade win their greatest victories. There is really no reason why the energetic, enterprising man should hesitate for a moment about undertaking prepara- tion for his home supply of vegetables. Commercial un- dertakings in vegetable growing may have to be confined to fewer plants grown just at the right season and with special methods, but even a small water supply with ample will and work will give a full variety for the family table. At certain elevations on the mesas and foothills of the Sierra Nevada and Coast ranges, sheltered by local topog- rophy, there are practically frostless regions with ample winter rains where winter growth is so fostered that the earliest vegetables as well as the earliest fruits are pro- duced. Some tender vegetables may be ready for the table on the higher location before it is safe to plant the seed on the lower level. And the two situations may be in full sight of each other. It is a fact that in small val- leys of the foothills late and early frosts, sharp and de- structive, may be more prevalent than on the lowlands of the broad valley below, while on the slopes above them tender plants may be safe. Mountain Valleys. — Among the mountain peaks and ridges from three thousand feet upward are slopes and valleys which are very productive of vegetables. As ele- vation decreases, wintry features become intensified and range of winter growth less and less until in the true "mountain valleys," which lie among the summits of the Sierra Nevada, the winter is a closed season of snow and ice and the garden becomes a summer affair as in the Eastern States. Growth, however, during the open sea son is very rapid and satisfactory, moisture is abundant 34 CALIFORNIA VEGETABLES. and irrigation facilities ample in the abundant supplies of snow waters from above, which need however to be moderated in temperature before distribution. In this region gardening seasons and practices are more compar- able with eastern policies and methods and are not charac- teristically Californian as the term is usually understood. GENERAL CHARACTERS OP CALIFORNIA CLIMATE. The proper conclusion from the foregoing discussion is that each California locality must be separately studied to determine its climatic adaptations for vegetable grow- ing and its season for the best discharge of the various gardening duties. There are, however, some generaliza- tions concerning leading climatic features as related to vegetable growing which may be of assistance to distant readers. Relative Occurrences of Cloudiness and Sunshine in Cal- ifornia Regions. — Due proportion of sunlight, warmth and moisture is necessary to produce quick and healthy vege- tation. Cloudiness is also an important element, since the presence of clouds screens the earth and diminishes the heat received by vegetation from the direct rays of the sun. So also, acting as a screen, it prevents in a measure the radiation of heat from the earth into space, and this materially tends to modify and reduce the daily range of temperature, so that growing vegetation is not subject to as great cold as would otherwise obtain during the night, nor on the other hand, does it receive the full amount of solar heat by day. It should be borne in mind that the weather condi- tions most favorable for vegetable growing are in some respects different from those which minister to the per- gection of fruits. The fruit tree, with its roots deep in a moist -soil, welcomes high heat to mature its fruit. The perfection of the esculent falls far short of the ma- turity of the plant and lies mainly in the measure and tenderness of foliage, stem, immature fruit or fleshy root. RAINFALL AND FROST. 35 These are usually best attained at a degree of heat less than required for fruit ripening. Again edible plants as compared with trees are shallow-rooting and suffer in a very hot surface soil which a tree escapes by penetration of the subsoil. The growth of winter vegetables is ad- vanced by abundant sunshine during the rainy season ; the growth of summer vegetables is promoted by cloud- screen from excessive sun heat, and it is clearly refreshed by summer fog. Herein, in part at least, lies the explana- tion why the earliest vegetables come from interior re- gions and the main crop of midseason and late vegetables is to be sought in regions whose climate is modified by cool coast winds, which sometimes carry fogs and always temper sun action by their content of insensible aqueous vapor. Some plants are especially responsive to this ac- tion of coast breezes. Lima beans on the Ventura coast are sometimes rescued from failure through deficient rain- fall, by days of cool, misty breezes from the adjacent ocean. The same is true in varying degrees of all vege- tation and the fact is often of very great economic im- portance to California. Distribution of Rainfall. — The local ramfall throughout the State has of course about the same relation to local gardening as it has to other farm work, but it seems hardly necessary to discuss it in this place, because it is possible now to secure the data from different sources. Local observers almost everywhere can furnish the facts. It is, however, pertinent to present a general compilation which fixes approximately the date at which effective rains may be expected in each main division of the State and thus impart a somewhat definite notion of when the natural season of growth will begin. All should be in readiness beforehand to seize upon this opportunity for soil working, if one is to proceed without irrigation, and for the planting of seeds of hardy vegetables which will withstand the local winter temperature and give the earliest readiness for use under the circumstances. 36 CALIFORNIA VEGETABLES. The Occurrence of Frosts in California. — The occurrence of frost in California is, from one point of view, a purely local question. As has already been stated, the frosty and the frostless places are often in sight of each other on the same landscape from the same point of view. It can be even more closely drawn than that. It is sometimes quite as plainly to be seen as the high-water line of a river flood on a sloping meadow. This occurs of course in what are termed the thermal belts and is determined by elevation, air currents, outflow levels and several other incidents of local topography. There are often wide va- riations in these lines from year to year and yet there is steadfastness enough about the phenomena to enable resi- dents to agree among themselves as to what localities are "in the frost" and what are out of it. Upon this decision depends the business risk in planting ont beans, peppers, tomatoes, etc., for winter growth, and it is upon such fields that the frost, not always content with the local definition of its limits, draws the dead line which the morning sun brings into such fateful prominence. Of course the grower is not necessarily content to accept such natural bounda- ries of the thermal belt. He can materially change it all by frost-fighting, but the discussion of that matter be- longs to another chapter. It is important to know as nearly as possible the be- ginning and end of the frost free period in each locality, and data to assist in determining this fact are given in the chapter on The Planting Season. CHAPTER IV. VEGETABLE SOILS OF CALIFORNIA. Soils which favor the most satisfactory growth of vege- tables are those which are most easily maintained in a con- dition of tilth to promote seed germination and rapid es- tablishment of the seedling in sure-growing contact with the soil-substance ; soils which facilitate deep-root pene- tration by the advancing plant so that moisture and plant food shall be rapidly reached, and which have sufficient retentive power and capillarity to maintain adequate mois- ture within reach of the roots and such amount of plant food that the plant may attain the greatest growth in the least time. Soils with these characters have also the most valuable incidental qualities of warmth, to foster vegetative processes ; porosity to facilitate the escape of surplus water and the entrance of the air with its con- stituents which promote root action and modification of the soil substance and absorptive power to readily receive and deeply distribute rainfall or irrigation. These are high requirements, for it is an ideal soil which possesses them all. Ideal Soils Not Essential. — Fortunately gardening art is amply able to supply- natural deficiencies in nearly all respects and, if he is working for high-priced products on a comparatively small area, the vegetable grower can of- ten profitably make considerable expenditure for soil im- provement. Market gardeners need no exhortation in this line, but the home gardener should be urged not to de- spair because of any refractory character in the soil he is obliged to utilize. If he study the subject by the aid of most excellent treatises recently written on the soil and 38 CALIFORNIA VEGETABLES. its amelioration he can proceed rationally and accom- plish marvels with Will, Work and Water upon almost any soil, from a brick yard to a desert. City people have grown their table supplies on housetops ; no ruralist can find a less productive subsoil. Light Rather Than Heavy Soils. — The characters already cited point clearly to what is commonly designated as a ^ather light soil as best for vegetable growing. The ex- creme variations in soils are popularly known as heavy adobe and light sandy soils. Neither are usually counted suitable for garden purposes without treatment to over- come their defects and yet as the terms are used in some California regions, there are very good gardens on both of them. The explanation is that in such localities one has less sand and one less clay than the other. Both are really loams or mixtures of sand and clay : one a clayey loam, the other a loamy sand. Aside from this misappre- hension of terms we have of course clays (locally called "adobe") which are true enough to the type to bring despair to the most patient gardener and we have washes of pure sand on which a shallow-rooting plant could hardly live with a stream of water running beside it. But our shifting sands of the interior plains and our so-called deserts are sandy loams which yield profusely when prop- erly irrigated. For the improvement of defective soils for the farm-garden, suggestions will be given later. Soils Naturally Excellent. — For field growth of vegeta- bles in California the grower is usually content to proceed upon the natural texture and fertility of his soil. The crop is chosen to suit the local soil and climate, conse- quently we have districts becoming famous for special vegetable products as demand for them in considerable quantities is demonstrated. In such districts the soils are rather light and yet ample in richness to endure for some time the drain of continuous cropping in the same line. We have areas of such soils considerably in excess of their present profitable use. They constitute one of our 40 CALIFORNIA VEGETABLES. undeveloped resources and are a surety of future advance- ment. For the very gratifying amount of accurate knowledge of California soils which is now available a debt of honor is due to Dr. E. W. Hilgard, formerly Professor of Agri- culture and Director of the Experiment Stations of the University of California, who has given a lifetime to ad- vanced investigations in soil physics and chemistry. It is from his publications^ that we shall condense some ac- count of the specific character of those soils which are most nearly related to local production of vegetables, leav- ing out of account the heavy adobe, which is little used for these crops except by gardeners who radically change its physical character. Prevailing- Character of California Soils. — In his inter- esting contrast of the soils of arid and humid regions, Dr. Hilgard makes some generalizations, which we collate to serve our present purpose. The character of the soils of the arid regions is predomi- nantly sandy or silty, with but a small portion of clay un- less derived directly or indirectly from pre-existing for- mations of clay or clay shales. The idea of inherent fertility has been associated so generally with soils of a more or less clayey character, that the newcomer will frequently be suspicious of the productiveness and desirability of the sandy or silty soils of the arid region that experience has shown to be of the highest type in both respects. Another point of great importance is that the differ- ence between soil and subsoil, which is so striking and important in regions of abundant rainfall, is largely ob- literated in arid climates. Very commonly hardly a per- ceptible change of tint or texture is found for depths of '"Soils: Their Formation, Properties, Composition and Relations to Climate and Plant Growth"; also "Agriculture for Schools of the Pacific Slope," by Hilgard and Osterhout. These works can be furnished by the Pacific Rural Press of San Francisco. CALIFORNIA SOILS RICH. 41 several feet and material from such depths, when thrown on the surface, is nearly or quite as fertile as the original surface soil. In the case of a cellar dug near Nevada City, the red soil mass excavated from a depth of seven to ten feet was spread over part of a vegetable garden near by and tomatoes, beans and watermelons were planted on it. The growth was even better than on the parts of the old surface not covered, which had apparently become somewhat exhausted by years of use. Examination has shown that the percentage of humus or vegetable mold is less in the soils of the arid region, but their humus contains more nitrogen. Thus, prob- ably, on the average not only is the aggregate supply of nitrogen in the soils of the arid region approximately equal to that of humid soils, but its absorption by plants is exceptionally favored bj^ climatic conditions. As to the minerals which constitute fertility, the soils of the arid region contain nearly fifteen times as much lime, five times as much magnesia, three times as much potash and about the same amount of phosphoric acid as the soils of the humid regions. Significance of These facts. — These leading characteris- tics of California's horticultural soils are of the highest significance to the vegetable grower because they show that California is rich in soils of ideal excellence for his purposes. They are light soils and therefore easy of cul- tivation and not disposed to bake on drying; they are deep, consequently well drained and yet absorptive and retentive enough : they are exceptionally rich, consequently extremely productive and durable and they can often be given a new fertile surface by deep turning from the fer- tility of the greater depths. This was the natural en- dowment which enabled the pioneer vegetable growers to disturb the hortieulaural peace of the world in 1849-50. It remains to foster the achievements of later yeai-s aiul it will endure definitely into the future. The distribution of these desirable soils gives all re- 42 CALIFORNIA VEGETABLES. gions a share in them. Either as residual loams resulting from the decomposition of adjacent rocks, or as transported loams which have been carried greater or less distances by wind, glacial action or other moving^ force, or as allu- vial or sediment soils, deposited by action of flowing streams, every California county has its vegetable soils in ample measure. Such is the diversity of soils within narrow areas in California that it may not take a very large farm to inclose several diverse types, and it is the first duty of the settler to learn their special characters and adaptations and plan his production accordingly. Alluvial or Sediment Soils. — Though there is marked diiference in the origin of our soils which are suitable for v^egetable growing, when proper moisture conditions are arranged, it is naturally the alluvial or sediment soils which have hitherto been chiefly used. They have been deposited by recent or ancient water courses and have formelrly served as river banks or river and lake bottoms. They have beneath them, generally quite far below, the prevailing soil of the adjacent country. They consist of fine alluvium with seldom any admixture of coarse mate- rials. They are usually very deep and well drained. They occur sometimes at a considerably higher level than ex- isting streams and are sometimes designated as "next to river bottom," while the lower levels constitute the "river bottom." In some small valleys they have spread deeply all over the original soil, having been washed in such quan- tities from adjacent hills, and in larger valleys have spread for considerable distances out upon the plain. These are primarily the fruit lands, but they are also largely used for such vegetables as thrive upon lighter and drier soils. Below are the present river bottoms, usually dark, rich and moist and not subject to baking or crack- ing, which are, par excellence, vegetable lands. Peat Lands. — Another class of alluvial soils is known as peat soils, which consist of mixtures in various propor- tions of silt and sediment with the debris of centuries' IMPROVING HEAVY SOILS. 43 growth of swamp plants which the streams have currently overflowed in flood times or over which they have risen daily as the tide wall has held back their waters. This organic matter from the aquatic plants is in various stages of decomposition, but in the best of the lands has been reduced to fineness by cultivation after the floods and tides have been excluded by levees, or by natural barriers interposed by stream or wave action, or by re- cession of lake waters according as the situation is on the coast or distant interior. This light but very deep and rich soil especially suits some plants and is the basis of some of our export vegetable business, as for instance, celery growing. Such soils are of course used locally for all esculent plants which thrive upon them and which the market favors. Such lands are in vast area in many parts of the State, from near the ocean to the margins of interior rivers and lakes and waters of interior plateaux as well. In the heat of the interior valley they dry out very rapidly when seepage or overflow from streams and sloughs is cut off by levees. They are non-retentive, owing to the coarseness of their structure, but irrigation is easily accomplished, as will be noted in the proper con- nection. IMPROVEMENT OF SOIL TEXTURE FOR GARDENING. Aside from such treatment of the soil as is designed to increase its fertility, which will be considered in the chapter on fertilizing, it seems fitting in this connection to suggest measures by which the texture of the soil may be improved when necessary. This is important in the farm garden because there may not be anything approach- •ng an ideal garden soil inside the line fences. But this fact should not discourage the home gardener, as has already been intimated. If one observes the operations of market gardeners or reads any treatise on gardening written for the older 44 CALIFORNIA VEGETABLES. countries, he is apt to conclude that the Creator has done little for the modern garden except to furnish a place to put it, because the chief art of gardening seems to con- sist in using as little of the natural soil as possible. This state of affairs has not arisen in California yet, for the reasons shown in the descriptions of our garden soils, and ,yet we do not mean to suggest that the farm gardener should in all cases expect to reach satisfactory results without due effort for soil improvement on the small area which he expects to yield so much. Improvement of Adobe Soils. — Our adobes, especially those of the darker hues, are rich and durable. In com- mon with heavy clay soils everywhere, they are retentive of moisture. In our arid summers, however, they lose their moisture speedily by evaporation, if untilled, and dry out to a greater depth than lighter soils. They are refractory under tillage and unless caught at just the right moment they are either wax or rock under the plow, and the cultivator will either stick fast or ride over the surface. And yet if one has nothing but adobe he is not as badly off as he might be, because adobe is easily suscep- tible of improvement. The points to attain are several, but they are inter-related and effort for one measurably helps toward all. The free use of air-slaked lime applied about the time of the first rains is the first and simplest effort toward breaking up the tenacity of the soil. This should be done no matter what greater efforts are to be undertaken later. Deep and thorough tillage, taking the soil at just that condition of moisture when it works well with plow and harrow, will be found to progressively improve its tilla- bility by mere action of air and implements. If this is all that can be undertaken at first, do this thoroughly and put in the cultivator after each heavy rain as soon as the proper condition of soil arrives, so as to prevent baking of the surface. For winter growth of vegetables in re- IMPROVING HEAVY SOILS. 45 gions of ample rainfall, use the ridge system, which will be described in a subsequent chapter. But liming and persistent tillage are only temporizing with adobe and do not accomplish permanent reform. The first rational step is to resort to adequate drainage. Tile drains two and a half or three feet deep and twenty feet apart will do for garden plants. This leaves a clear surface for working over, but, if the expense of tiling is not desired, open ditches will answer, but they restrict cultivation to one direction, waste land, and are expen- sive in hand work in killing weeds in the ditches. Open ditches are, however, better than no ditches at all. The effect of drainage is to promote friability, to render the soil tillable earlier and oftener, by the quick removal of surplus water, and to promote seed germination and plant growth. The aeration of adobe by drainage and tillage accom- plishes a considerable improvement but still more radi- cal reform measures are desirable. The soil particles are naturally too small. They must be separated by interposi- tion of coarser grains. Plow into the soil as much coarse material as possible. Farm-yard manure, straw, sand, old plaster, coal ashes, sawdust, almost anything coarse or gritty which will break up the close adherence of the fine clay par- ticles, release the surplus water and let iu the air, will l)roduce a marked effect in reducing the hateful baking and cracking, root-tearing and moisture-losing be- havior of the adobe. Scrape the corrals, rake up the leaves and fine litter of all kinds, make the adobe garden patch the graveyard for all the rubbish which is susceptible of decay. The farm will be neater and the garden will pay the expense in its easier working and better growth. Do this every year before the rains come, and you will rejoice that you had an adobe foundation for the farm garden. The Improvement of Light, S::ndy Soils. — This effort is in some cases more difficult than conquering adobe.

If soil and su))soil are coarse sand or gravel to a considerable depth, shallow rooting plants will fail unless they can finish their growth during the rainy season. Summer growth is impossible because water will flow through their sieve-like structure and carry away plant food with it. With moisture leaching away below and flying away above, and with intense sun heat burning the foliage by direct contact and reflection, such wash soils are indescribably worse than adobe. But sandy soils which are imposed upon clay or hard- pan, providing the underlying stratum is not alkaline, furnish very promising garden materials, even though the layer be too shallow for the growth of trees. Many fruit growers are struggling to maintain trees on such spots in their orchards when they should forsake the ef- wort and by adequate use of water and manure turn such spots into family gardens. The holding of water near the surface, which is fatal to tree roots, is the opportunity for the growth of most vegetables. Depth of soil which is so strongly insisted upon in treatises on gardening, con- stitutes a storehouse of moisture and plant food, but it has been abundantly demonstrated the world over that depth is not essential provided the plant is otherwise fed and watered. California gardens proceeding upon rain- fall alone, need a deep, retentive soil; the irrigated gar- den may thrive upon a soil too coarse to be retentive pro- viding it has a tight bottom to hold moisture within reach of shallow rooting plants. Therefore reclaim such sand by providing a home water supply, if not in an irrigated region, and use plenty of well-composted and decayed ma- nure, which will not only feed the plants but will also reform its texture and transform the coarse sand into a rich garden soil, kind in cultivation and prodigious in its yield of succulent vegetables, for sand is best of all ma- terial for free and rapid root development. CHAPTER V. GARDEN IRRIGATION. It has already been intimated that the irrigated garden should be the aim of all who desire to attain the fullest satisfaction in vegetable growing. But while it is true that the California gardener must have irrigation to do his best and to give him a solid year of rotations and successions in his garden, due emphasis must be laid upon the fact that in suitable locations the unirrigated garden in California is a greater treasure than at the east. This fact is due to the character of our winter climate, which, as has been shown in a previous chapter, is actually a growing season for all but the vegetables which will endure no frost. By using to their fullest capacity our six rainy months, by early cultivation and planting, which will be fully explained later, midwinter and spring vege- tables can be produced in great variety ; and by proper cultivation for the retention of moisture, tender vegeta- bles, planted toward the end of the rainy season, will find moisture enough stored in the soil to carry them to perfection in midsummer and autumn, although not a drop of rain may fall from the sowing of the seed to the gathering of the crop. For this reason owners of fairly deep and retentive soil in regions of ample rainfall can attain splendid results without irrigation, if they will only be alert for prompt work and persistent in summer cultivation. What can be done in California with the unirrigated garden depends upon conditions existing in each locality. Character and depth of soil, amount of rainfall, degree of heat, and percentage of relative humidity in the air, 48 CALIFORNIA VEGETABLES. the lay of the land — all these are determining factors, in addition to the dates of frost occurrence which fix the opening and closing of the season for tender plants in the open ground. Therefore let no man conclude that he cannot grow vegetables until he completes his arrange- ment for irrigation unless he is sure that his winter rain- fall is too uncertain to grow even a crop of wheat, for a rainfall that will carry the wheat plant to maturity will also produce quite a variety of garden vegetables with proper practice in early sowing and frequent cul- tivation. And from this low-water mark the unirrigated garden proceeds upward with richer endowment of favoring local conditions, insuring length of growing season and variety of vegetables until it really becomes a question whether irrigation is needed at all. It certainly is not for ample yield of many, possibly all, of the staples of the garden, but to insure a succession of salads and relishes, pot- herbs and legumes — in short, to enjoy the fulness of the California season, the irrigated garden is the thing to be diligently striven for. SOURCES OF IRRIGATION WATER. Whence the garden shall receive its water supply is a question for each to determine according to his environ- ment. Water is now flowing over California gardens from various sources as the result of all sorts of indi- vidual, co-operative, and corporate efforts and invest- ments. It would require volumes to clescribe them. Large irrigation enterprises are the joint work of engineers and capitalists. That gardener is fortunate who has only to buy his water from a fair-dealing ditch company or draw his share from a co-operative water company in which he has an interest. Such a source is best of all because causing least labor and expense in average cases. But there will always remain opportunities, probably, where farm gardens can command their own irrigation supplies SOURCES OP WATER. 49 at a cost which will warrant the effort. It is in this line that a few suggestions will be offered. Surface Sources. — In the unirrigated regions of the State there are countless opportunities for home supplies .„^''* ■ tkM< u^s^.- *^l W:-V BOGGY LAND PRODUCED BY SEEPAGE. j>7v,A«i-''V- RECLAIMED BY RESERVOIR BUILDING. of irrigation water by the simple process of allowing it to run down hill your way instead of that way which is natural to it. Water which would be of great value in the house and barn and farm garden is allowed to flow by in its own deep channel when a very little use of the 50 CALIFORNIA VEGETABLES. level would show that a part of it could be taken out into a ditch or pipe, higher up its course through the farm, and brought along with less fall than it naturally takes, until it reaches the buildings high up the slope above the bank instead of in the deep bed it has cut in the soil below. This is very simple and inexpensive, and yet we have many hillside places in the central and north- ern parts of the State where the water is carried up by hand to the house, and the animals are driven down to the water, and the garden is neglected because it is too hard work to haul water up to it. Of course, there are many eases where such an obvious resource of the farm has been utilized, but there are many where it is neglected. Many springs on the hillsides are allowed to be trampled into mudholes by the stock, which need but cleaning out and opening up to yield a water-flow beyond any amount which the old outcropping would indicate. A short pipe line would deliver water in the tops of the buildings if desired and would generously irrigate all the land needed for the family garden. And yet the hillsides are full of unused springs. Between the hills above the building sites there are many intervales which are impassable in the rainy season and covered with a growth of sedges and swamp grass all summer. They are natural reservoirs of greater or less capacity, holding the surface water and underflow from the hillsides. In the dry season plowing and scrap- ing will easily fashion a small reservoir at the lowest point of the intervale and a pipe line will bring down water at least for irrigation, if it is not suited for other uses. Or if there be below a better site for a reservoir, underdrainage of the swamp will turn it to the growth of good grasses while the outflow from the drains can be concerted into garden crops below. Again even when the surface after the rainy season shows no sign of moisture, it is often possible to keep a good supply in sight by closing some small vale and dry SOURCES OF WATER. 51 creek bed with a dam to hold for summer use in the garden some part of the volumes of water which rush down from the watershed during the winter rains. Subterranean Water Sources. — There are few places where water for a home garden cannot be had by well- digging and there are many large districts where flowing wells are secured by shallow boring. At the bases of hills horizontal wells or tunnels are frequently satisfactory. The capacity of these wells and tunnels is sometimes very great. They often warrant long-ditch lines or figure in the supply of towns and cities. Unquestionably the pres- ent development of water by these means is only a frac- tion of what is possible, and the owner of untried land should undertake a reasonable amount of prospecting. It is, of course, easy to waste money in this way, but if one proceeds after as full study as he can make of the surface, the outcroppings of rock, the experience of others in the same region, he is pretty sure to realize upon reasonable anticipations. Excavation in dry creek beds of gravel and boulders have often brought to light considerable underflow which has been arrested and the water stored by cement dams resting on the bedrock. Flowing wells and wells which bring the water near to the surface constitute the main source of subterranean water employed in California. They have reclaimed large districts which were formerly arid wastes and they are largely used also for summer crops in the regions of ample winter rains. Well borers equipped with good appliances are to be found in all parts of the State. WATER-LIFTING DEVICES. At this point it will be well to remark that any gardener is fortunate who has water brought to the highest point of his plantation by its own weight without a struggle on his part against the force of gravity, and yet there are, of course, hundreds, perhaps thousands, of instances of 52 CALIFORNIA VEGETABLES. satisfactory home gardening by simple water-lifting de- vices. Horizontal Windmills. — Devices based upon the over- shot-wheel principle are used to some extent on this coast, but the summer winds at the ground surface are usually too light to operate them well. In its simplest form this windmill consists of four boards, about seven feet long, fastened to long arms projecting from an axle, which has bearings on two strong posts or a framework. The wind only strikes the upper part of the wheel, the lower part being inclosed by a board fence. In a slight breeze the mill revolves about 20 revolutions per minute, but in a good, stiff gale it flies so fast that a sliding board must be raised to shut off the wind. The wheel is connected with the plunger of the pump by means of a crank at one end of the axle. Gasoline and Crude Oil Engines. — These devices have been greatly improved during the last few years and are now being largely employed for water lifting for irriga- tion. There are several manufacturers in California, the fuel is very cheap here, and this, in connection with the ease with which the engines are managed, constitute them most economical and satisfactory agencies for pumping. The manufacturers give full information and can usually cite engines in operation in different localities where their performances can be personally ascertained. Steam Engines. — Pumping plants of great capacity operating by steam power are also in use for irrigation. Large vegetable growing enterprises render considerable investment in these lines profitable. Their construction and operation are, however, rather beyond the scope of this work. The advice of a mechanical engineer should be secured in all large undertakings. The Chinese Pump. — A water-lifting device which is very effective for a short lift, as from a ditch or stream to adjoining lands, is the Chinese pump, which has long been in use in California. It is a modified "Persian LIFTING WATER. 53 wheel," and is so simple that it can be home-made with old threshing machine gearing or other mechanical junk. It consists of an endless belt working like the "elevator" or "straw carrier" of a threshing machine. For instance, take an old machine belt eight inches wide and twenty feet long or sew together strong canvas to make one. Make a box or trough about nine feet long, eight inches wide and six inches deep inside measurement, with no ends nor cover. Rig at each end of this box a wheel or pulley over which the endless belt can run. Fasten to the belt, a few inches apart, blocks scant eight inches long and four inches wide, so that the belt will have a flat surface on one side and the other crossed with the blocks. When this is placed in the box and over the pulleys at each end fasten the box securely in an inclined position with the lower end in the water, turn the upper pulley by a hand crank or a small belt from a source of power and the blocks will elevate the water and shoot it out from the top of the box in fine style. For a short lift this apparatus discharges quite a large volume of water with compara- tively little power. DEVICES FOR SELF-LIFTING WATER SUPPLY. Where running water is at hand in ample supply and with adequate velocity, the water can be made to lift itself to a distributing point, if not too high. The most capa- cious agencies belong to a class of motors called current wheels. Current Wheels. — A current wheel is an arrangement resembling the paddle wheel of a steamboat, with a cen- tral shaft acting as a hub for spoke-like arms which carry on their ends boxes or buckets. The wheel is hung by the projecting ends of the shaft so that the buckets are just covered under the surface of the water. The current catches them and caused the wheel to revolve ; the filled buckets are carried up as empty ones descend in the water. The filled buckets are emptied as the turning of the wheel 54 CALIFORNIA VEGETABLES. inverts them, and the water is caught in a box properly placed and is then conducted by a flume to the point of discharge. Current wheels are largely used for short lifts from streams or irrigation ditches in which the water flows with sufficient velocity to revolve them. The wheels are usually home-made, and much ingenuity can be em- ployed in constructing them of available materials. Hydraidic Rams. — The hydraulic ram is wasteful in that it can deliver at a higher level but a fraction of the water furnished it and it requires a definite fall for its action. Where conditions are favorable it does become an effective agency because it acts incessantly and, with suitable stor- age, considerable amounts of water become available for irrigation. Manufacturers of hydraulic rams furnish full accounts of their requirements and achievements. A suggestive combination of current wheel and hy- draulic ram, in operation in this State, is described as follows : "A. P. Osborn's residence and the best part of his land are located on high grounds on the bank of the Tule river, at Rural. To get water on this land without going several miles up the river and bringing out a ditch, Mr. Osborn has placed in the river a wheel twenty-five feet in diameter and five feet wide. Surrounding this wheel on either side are forty boxes, each holding four gallons of water, mak- ing in all eighty boxes, with an entire lifting capacity of three hundred and twenty gallons at each revolution of the wheel, which is turned by the current of the river. As the boxes reach an elevation of tAveuty-two feet, the water in them is emptied into a flume, which conducts it onward into an irrigation ditch. This elevating the water twenty-two feet is only sufficient to place it on the flat whereon is done the farming, and will not take it to the knol] on which stands the residence. This is accomplished by a hydraulic ram. A part of the water reaching the top of the river bank is allowed to run l) o 12; Q ►-3 3 < >-> Beans * *- *- *2 *:•. *:■■ * * * Beets * * * * * * * * * * Cabbage * * * * * * * * * * * Carrots * * * * * * * * Cauliflower .. . * * * * * * Celery * * * Corn * * *3 *;; * * * Cucumbers . . . *n * * Eggplant *2 *2 *2 * * * Lettuce * * * * * * * * * * * * Melons * *:i *.-; * * * Onions . . * * * * * * * * * Peas * * * * * * * * * Potatoes * * *- *-' * * * * * * Potatoes, sweet * * * Radishes * * * * * * * * * * * * Salsify * * * * * * * * Spinach * * * * * * * * * * * * Squash * *:; * * * Tomatoes .... *- *2 *-■ *J *2 *:: * * * Turnips * * :li * * * * * * * 'On irrigated land.

THE FROST FACTOR. 147 TIMES FOB PLANTING CEKTAIN VEGETABLES IN VALLEY AND F( REGIONS OF CENTRAL AND NORTHERN CALIFORNIA. H,ularity. Recently the California can- taloup has figured largely in the overland trade. THE MUSKMELON. In the United States the terms "muskmelon" and "can- taloup" are interchangeable, and in California cantaloup is given the preference. Of the many types of cantaloups which have been defined by students of melon classifica- tion a single one, known as the Rocky Ford, from the place of its large commercial development in Colorado, 278 CALIFORNIA VEGETABLES. dominates all others, commanding nearly all the acreage and constituting almost exclusively the commercial pro- duction except that which is especially grown for local markets. The muskmelon has a very wide range in California. It has greater taste for dry heat than its relative, the cucum- ber, but in this respect it is no rival of the watermelon, for it will perish utterly under drought which the watermelon will survive. Where the muskmelon has both heat and moisture, it grown riotously, for a weight of 72 pounds has been reported from Fresno. But the muskmelon will not brook frost, nor will it thrive with low temperatures even if they are considerably above freezing. California has, however, such a long frost-free period and as degrees of favoring heat arrive in different months in different parts of the State, there is wide divergence in dates of planting and of ripening of the crop. The earliest canta- loup district is the Coachella and Imperial valleys in the extreme southeast corner of the State. Planting is done in February and the crop shipment begins in IMay and reaches the Eastern markets in advance of the product of Colorado and other interior States. In the San Joaquin valley planting may be in April and the product follows the Kocky Ford shipments for the later summer trade of the Atlantic cities. Just what can be profitably done at different dates in the East is not fully determined, but the advantage of the very early cantaloup from California seems unquestioned. It is clear, however, that by choos- ing different parts of the State and different varieties of cantaloups, including the 'Svinter melon" class, Cali- fornia can furnish the fruit from May to December in any (piantities the available prices make profitable. Garden Culture. — The soil requirements of the musk- melon are quite like those already described for the cu- cumber. Most of the commercial crop is produced on deep, rich, warm loams, but heavier soils with good cul- ture may be used. Some varieties seem to enjoy a heavy soil better than others. Preparation of the soil is the same w: ■ tv, ■■■, '• ■;■ ' ^^. - '» ^: ■ ;•■ V •■ '• ;- A* M: Ji ■- r^;-//^'^./ ■■'f.5^'- i^^-^'"" 280 CALIFORNIA VEGETABLES. as for cucumbers, and the same methods for starting plants for planting out as well as for furnishing warmth and richness in the hill may be used in garden practice. In the interior, on the naturally rich loams, not only is the culture devoid of all forcing devices, but on moist river bank or bottom soils the early crop is sometimes grown without irrigation. For summer planting and the con- tinuation of the muskmelon supply late ni the fall, ample moisture is necessary, and a modification of interior heat by intrusion of coast breezes is desirable. The late sum- mer product is most easily grown in the coast valleys, somewhat protected from ocean winds. Field Culture. — There are so many ways of handling the soil to secure fine tillage and aeration and adequate mois- ture without the evil of surface flooding that it can be hardly claimed that any one routine is best. As involv- ing tillage, irrigation by percolation and fertilization, which the plant enjoys under proper conditions, the fol- lowing outline, condensed from the writings of Dr. R. H. Forbes, of the Arizona Station, is very suggestive for Cali- fornia interior valley conditions. The writer has made some additions from his own observations: Cantaloups are grown to excellent advantage on light warm loams properly fertilized by the addition of the organic matter and nitrogen in which our desert soils are usually defici- ent. Heavy soils may also be used for cantaloup culture, but are less easily prepared and tilled during the progress of the crop. Old alfalfa ground is most excellent for can- taloup culture, and well rotted barnyard manure is effec- tive. Bermuda sod plowed up and exposed to the sun without irrigation the preceding summer makes excellent cantaloup ground, the intensive cultivation necessary serv- ing both to benefit the crop and to restrain this formidable weed. Trash from sod-turning can be reduced by the use of a disk. Alkaline lands should be avoided, since soluble salts in excess, even though insufficient to kill the plants, are com- IRRIGATING CANTALOUPS. 281 monly believed to be detrimental to the quality of the melons. The land should be so laid out that the rows may be irri- gated without submerging the vines and the fruit. One good way to accomplish this, and also to fertilize the soil, is as follows : The field is first irrigated, plowed and har- rowed to a condition of fine tilth. With a 12-inch plow, at intervals of six feet, double furrows are then broken out, going and returning along the same lines. In the deep, wide furrows thus formed well rotted barnyard manure is distributed to a depth of three or four inches, then plowed in and the field again harrowed level. By then plowing toward the middle of the spaces between the fertilized furrows, the soil is finally left in oval ridges separated by back furrows for irrigation. The rough furrows and ridges are then finished with a harrow and the newly pre- pared ground irrigated to establish the water line for guidance in planting. Seed should be most carefully selected with reference to flavor and appearance of the fruit ; to good shipping char- acters, including small cavities and heavy netting ; and to a tendency to produce melons of standard size. About one pound of seed is required for an acre. Cantaloup seed improves to some extent with time, and is stated by ex- perienced growers to give more satisfaction at two years of age than at one. With irrigating furrows six feet apart, rows may be planted one on each side of each furrow. The hills should be ten feet apart in the rows, "breaking spaces" between rows. On this plan the ground will be quite uniformly occupied, with a distance of about six feet between ad- jacent hills. Where winds are strong and prevalently in one direction it is sometimes desirable to lay off the lands at right angles to the course of the wind and plant all the hills on the windward side of each strip so that the vines are trained by the wind away from the ditch and not half of them blown into it. With a hoe each hill is planted by making a small fur- 282 CALIFORNIA VEGETABLES. row a foot long just above the water line, made by the pre- ceding irrigation which places the hill where it will not be flooded by later irrigation. About ten seeds are dropped in this furrow, covered an inch deep, and the soil pressed down lightly with the blade of the hoe. After early plant- ings, when frosts are feared, a second set of hills may be planted alongside the first, ten days or two weeks later. VARIETIES OF CANTALOUPS. 283 When danger from frost is past, while the plants are still small they are thinned to one or two of the strongest to each hill. Care must be taken not to overcrowd the ground with vines, as a high percentage of small melons will fol- low. Under Arizona conditions the six-foot spacing of hills recommended above, with not more than two plants in the hill, gives best results. A dependable supply of irrigating water is essential to successful cantaloup culture in regions of little rain. Early in the season when the plants are small and the irrigating supply is cold, water should be applied sparingly. But be- tween the setting of the crop and the ripening of the first fruits, when both vines and melons are developing rapidly and when the weather is usually hot and dry, frequent and copious irrigation is necessary, for if water is stinted at this time a large percentage of small or pony melons is likely to follow. During the picking season water should again be sparingly applied — just enough to prevent the vines from wilting. This also gives quality and solidity to the melons. As long as the vines will permit, the middles should be kept free of weeds by means of a one-horse cultivator, and the furrows run through with a small plow after each irrigation. The young plants should also be hoed by hand two or three times. When the ground is once well covered with vines weeds will make but little headway, even Ber- muda grass being effectually checked by the dense cover. Varieties. — The wonderful advancement of the canta- loup as a commercial product during the last decade has quickened effort for new varieties and given new incen- tive to sharp selection to secure characters likely to facili- tate long shipment or to increase the demand. Relatively small size, symmetrical form, thickness of flesh and reduc- tion of the seed-cavity, durability, flavor and color of flesh are among the improvements which have been dili- gently sought. Each year brings forward something new and worthy of trial to determine local behavior and suit- ability. Obviously a book which aims to be useful for a 284 CALIFORNIA VEGETABLES. number of years after its publication cannot satisfactorily serve fis a guide to choice of varieties which are constantly changing. Annual catalogues of California seedsmen should be carefully consulted and every grower should try all promising novelties on a small scale. Rocky Ford : The variety upon which the Colorado can- taloup industry is established and it sustains the same re- lation to the commercial-product of California; developed by selection from the old "Netted Gem"; slightly oval, finely netted, average weight 1% pounds ; flesh green, thick and very sweet. Continued selection is being prac- ticed upon this variety and "Netted Rock" has been fa- vored in this State on the claim of heavy bearing and greater average production of standard melons. Burrell 's Gem : Larger than Rocky Ford ; flesh reddish and of different flavor ; an improved Paul Rose, which it has largely displaced. Hoodoo : slightly flatter than Rocky Ford but otherwise similar ; flesh reddish. Large Yellow : an old variety, large oblong, slightly ribbed and coarsely netted ; flesh light, yellowish green ; quality excellent; still popular though very different from modern commercial types. California Large Nutmeg: an old variety still popular in local markets and good for shipping ; large, rough, net- ted skin ; flesh thick, solid, dark green ; flavor delicate. Montreal Improved Green Nutmeg : large, slightly flat- tened at the poles, densely netted skin, flesh thick and of good flavor. Early Hackensack : large size, productive, excellent flavor. Large Hackensack : large size, roundish, very prolific, thick, juicy flesh, rich in flavor. Cassaba, or Pineapple : fine, large, late variety, rich, cream-colored flesh ; keeps well into the winter. The small, early varieties, like Jenny Lind, are not largely grown, as the trade prefers the large nutmeg va- THE WATERMELON. 285 rieties. The small varieties are, however, very desirable for home use. The Winter Melons. — One of the most interesting and promising phases of melon growing in California is the ad- vancement of the "winter melon," comprising several types, of which the first to reach California was the Cas- saba or pineapple melon which was introduced in two va- rieties : one by the late General Bidwell, of Chico, in 1869. and another by the late Dr. J. D. B. Stillman in 1878. Of these the latter has secured the greater popularity. Later introductions and selections and probably hybridizations also, have brought half a dozen quite distinct varieties into notice and a considerable product has been secured both for local sale and distant shipment during the late autumn and early winter. Which varieties will survive cannot be told and in this line California seedsmen's catalogues must be consulted each year. On irrigated lands these melons can be sown in mid-summer and find ample autumn heat and freedom from frost to reach perfection. The ripe fruit remains in good condition for months without cold storage. THE WATERMELON. The watermelon is more strictly a warm region plant than the muskmelon. It reaches great size and sweetness in interior regions of highest heat, coming nearer to the coast in southern California thm in the upper part of the State. The heat is, however, high enough in some of the coast valleys and foothills, which are in some part sepa- rated from the coast by high ranges, to produce a very good watermelon. The gratefulness of the interior climate of California to the watermelon is seen in the way the plants volunteer wherever on cultivated land a melon may have gone to decay. In cultivated orchard they may almost be called weeds, though sometimes the volunteer crop is turned to account. A case is cited where watermelons were planted between the trees in a young orchard. After the melons 286 CALIFORNIA VEGETABLES. were harvested, and before the volunteer crop appeared the following year, the ground was plowed twice, har- rowed twice, and cultivated four times in the regular course of orchard work. Notwithstanding all this dis- turbance of the soil, the seeds, which remained in the ground during the warm rains of winter and spring, did not sprout until June — considerably later than seed sown that year, and produced as good a crop as the latter. Be- ing, probably, deeply covered they awaited the penetra- tion of the warmth, which came first to the seed sown near the surface. The soil was a light loam, naturally well drained, and the seed abided its time in good condition. Soils. — Soils which best suit the watermelon are warm alluvial soils, and the plant thrives on a lighter, drier soil than suits the muskmelon. It does well on a light soil with a retentive sub-soil, which acts as a reservoir of mois- ture. In such a case the surface soil may be coarse or even gravelly. Good specimens have been shown which have been grown without irrigation on recent deposits of mining detritus ; on the other hand, good melons are grown on rather stiff clay loam. On heavy land much is gained by plowing under a winter-grown sod or green crop, or a covering of manure, which renders the soil more permeable as well as enriches it. The plant seems to tol- erate many conditions, but neither cold nor wet agrees with it. Culture. — The preparation of land for watermelons is like that for sugar beets, already described. In regions of heavy rainfall the fall plowing should be done with enough dead furrows to remove surplus water so that the spring plowing may not be delayed by wetness. Two spring plowings and pulverizations are desirable on the heavier soils. The land is laid off with a marker in six or eight feet squares, and planted, after danger from frost is over and the ground is warm, with 10 or 12 seeds in a place to cover accidents and insects. These are reduced at the first hoe- ing to one or two plants in a place. The cultivator should VARIETIES OF WATERMELON. 287 be used as soon as possible to prevent crusting of the soil, and cultivation should be kept up until it interferes too much with the growth of the vines. During the first two months of their growth the cultivator is almost constantly running in the melon fields. Time of planting is, of course, dependent upon the frost record of the locality. To get the earliest melons, grow- ers often take the chance of replanting by planting in March if it is an early spring and the soil is in good con- dition. In light interior soils the most of the planting is done in April, and in frosty situations early in May. For succession, planting can proceed on moist or irrigated land until July, and in frostless locations July planting will give ripe melons as late as New Year's. Harvesting". — When early sowings succeed, melons can be had in June in the interior, but the weight of the crop comes in July or August. An average yield in field cul- ture is one carload, or one hundred dozen melons to the acre. Sizes run from a common merchantable size of 20 pounds up to a monster of 131% pounds, grown in Los Angeles county many years ago. Melons of 90 to 100 pounds have been reported from all regions which make any pretentions to greatness in this line. Varieties. — Everything offered by seedsmen in the form of an improved watermelon is quickly put into California soil. The result is that in the State as a whole very many varieties are grown, probably as many as of any single garden plant. Still a few varieties are easily leading in popularity. The most famous variety in the central part for the last quarter of a century has been the "Lodi, " a variety believed to be of local origin, taking its name from the locality where largely grown, in San Joaquin county, but the Lodi is now yielding even in its own region to other varieties, and its decadence is probably in part due to lack of proper selection in seed sowing on the part of the growers, and the superiority of newer sorts.

The onion is another of the great vegetables in Califor- nia — great in the size of the tubers and in the crop, great also in the ease with which a constant supply of fresh onions can be secured throughout the year in the oj^en air ; greater still, perhaps, in the fact that the superb local conditions for onion-seed growing have given California the power to set prices for the onion-seed trade of the 290 CALIFORNIA VEGETABLES. United States, and we have sometimes prodnced more seed than could be sold with profit to the growers. Though the local consumption of onions, in proportion to the popu- lation, is large, and though there is an export trade in all directions, there is now and then an over-production and a reaction even to scarcity, so that the market price is sub- ject to wide fluctuations. A more trustworthy demand would develop a producing capacity w^hich has thus far hardly been entered upon although during recent years distant shipment of onions has notably increased. The California onion product sometimes exceeds 300,000 s feet apart and set 21/2 feet apart in rows. Should the weather be dry and irrigation necessary plow a furrow beside each mark and run water in these furrows before and after planting, and if the Aveather be very hot two or three irrigations may be necessary to start plants. Always allow 24 hours after irrigating before plants are set, unless soil is very sandy. Then work may commence sooner. When through with the irrigation furrows, plow back and cultivate the land until level as before. Keep soil in good growing condition always. When plants are 12 to 15 inches high use a ridger (such as is used in raising levees for irrigation checks) with plenty of space open behind and straddle each row, thus drawing the earth to each side of plant and giving it support. Water may be run down these rows at this time. As plants grow make the ridge wider with a crowder run in between each row. This ridge will keep plants from breaking down so readily when laden with fruit, and when fruit strikes the ground 314 CALIFORNIA VEGETABLES. it will not decay so readily because the ridge will be dry. Do not make your first ridging too high, and do not do the work too late; if so, the first setting will be greatly injured by pushing the earth against the fruit, thus leav- ing no room for it to grow, and many pods will be curly and eaten by bugs. Gathering and Curing. — During September the fruit will begin to ripen, the time of ripening depending upon the soil and the care of the crop. In sandy soil the fruit will ripen quicker than in deep sediment. If the plants lack moisture they will ripen much faster, which looks well, but they should be kept green as long as possible. It pays better in the end. The crop should be picked as each setting ripens ; go over the field three or four times. A pod should be left on the vine until of a dark red and it has lost its hardness, being somewhat pliable. Have the crop gathered in large baskets, but they should be hauled in boxes rather tJian sacks, as they are less liable to be bruised, and a bruised pod is liable to decay unless dried at once. If peppers are to be dried on strings, have them dumped on a table or on the ground, as you prefer. Allow 24 to 48 hours for stems to wilt after gathering before they are put on the string. This work is done by running a twine through the stem of each chile, the twine to be 10i/> to 11 feet, and same may be hung on a scaffold to dry or put into espe- cially made evaporators. Some growers report favorably on drying their crop on trays instead of on twine. During recent years most of the drying has been done in evapor- ators, which is accomplished by artificial heat in six or eight days. Soils for the Commercial Crop. — Although peppers can be successfully grown in any good garden soil, it is im- portant for the field crop to choose deep, rich, sandy loam, or sediment soil, which will not bake very rapidly. The young plants must be set in damp soil and if land should easily bake it will become hard and will dry out more readily about the young plant and the growth will be very VARIETIES OF PEPPERS. 315 slow. It is not wise to grow more than two crops of pep- pers on even the best of soils without fertilizing very liberally. Cover crops plowed under are found very profitable. Varieties. — The varieties chieliy grown for home use and marketing green are Large Bell or Bull-nose, an early variety of mild flavor, fruit large, slightly tapering and generally terminating in four obtuse, cone-like points. It is a favorite sort, both for pickling and for table use. Sweet mountain is another popular variety similar to the foregoing, but larger and milder in flavor, and Chinese Giant is an immense pepper, often twice as large as Large Bell. The standard for hot pepper and for the dried crop is the Mexican chile, long, narrow pods on a low-growing, narrow-leaved plant. One type is a very dark, thick- meated, cone-shaped chile, growing from 4 to 6 inches long, which is gaining ground ; while the Long Red, or Anaheim Chile, having pods from 6 to 10 inches long, is the best known. The plant is strong and holds its fruit up well and is very productive. There is also a longer variety with pods up to fourteen inches in length which, however, is claimed to be less productive and light when dried, though the flesh is quite thick when green. CHAPTER XXVIII. POTATOES. The Potato. — Solanum tuberosum. French, pomme de terre ; German, kartoffel ; Dutch, aardappel; Danish, jordepeeren; Italian, patata ; Spanish and Portuguese, patatas. The Sweet Potato. — Convolvulus balafas. French, patate douce; Italian, patata; Spanish and Portuguese, batata. Potatoes may be grown everywhere in California with- out irrigation, except on strictly arid plains and deserts, and it needs but slight watering to enable the light but rich soils of the arid regions to surpass the naturally moist lands both in the size and quality of their produce. Some of the grandest potatoes every grown in the State have been taken from light, w^arm soils whose natural growth was sagebrush and other desert flora. The superiority of the higher, lighter lands, either with adequate rainfall or irrigation, to the moist lowlands of the interior river bot- toms or the coast valleys, has been clearly recognized during recent years. In the -earlier days, the coast and the interior river bottoms w^ere supposed to be par ex- cellence the potato regions, and their products were trans- ported great distances to interior uplands which were thought to be unfit for the plant. Now the choicest po- tatoes are grown in these places and the production in the older regions has decreased, though the potato still constitutes an important crop. The present situation is that the potato may be seen everywhere from the skirts of the cliffs which look down upon the ocean, along the bottoms and sides of the coast valleys, on the reclaimed lands and benches of the great interior rivers, up the REQUIREMENTS OF POTATOES. 317 slopes of the foothills and in the monntain valleys of the Sierra Nevada and out beyond, upon the stretches of sage- brush, wherever water can be had to turn the desert into a garden. California has capacity for a potato produc- tion beyond the ability of any available market to handle, and though a few years ago it seemed likely that our cli- matic advantages in early production would give us com- mand of distant consumption at certain times of the year, it has since been shown that much less can be profitably done in this direction than was anticipated. There have been in some years very large shipments at reduced freight rates when the Eastern production was deficient, but the potato is ordinarily too cheap an article to endure the cost of long transportation. The California potato product sometimes exceeds 3,000,000 sacks per year. Situations. — ^Though, as has been stated, the potato grows wherever adequate moisture is assured, there is much difference in the times of the year at which maturity is attained. Though the potato is a tender plant it will endure light frosts, nor does it always yield its life when the frost blights the foliage. Dormant buds lower on the stem develop into a new top growth. It is, therefore, pos- sible to secure fall and even winter growth in places where a strictly tender plant like the bean would perish. Where only light frosts occur and where irrigation is provided to supplement rainfall, it is possible to have new potatoes all the year and to bring to edible condition three crops suc- cessively on the same ground withing a twelve month, though it is, of course, better to let the potato take its place in a rotation. New Potatoes. — The first new potatoes from a California point of view, would be the crop that comes in the autumn with the first green peas — counting July 1 as the begin- ning of the garden year. In fact the first potatoes and peas come from the same localities. They make their growth in the fall from planting on ground well soaked by irrigation in July and August. The regions for this work are those in which fall frosts are light or do not occur at 318 CALIFORNIA VEGETABLES. all — the tlu'r'inal l)c']ts at (liffcrciil elevations on the hill- sides both on the Coast Ranye and the Sierra Nevada, also on the warm interior plains, hut not usually on the river bottoms nor on the low places in small valleys. Owing, however, to the partial resistance to frost of the potato, there are very wide areas both on the coast and in the in- terior of central and southern California, where the fall growth of potatoes is safe and worth wider attention than is given to it by home gardeners. Where irrigation may be had to start the seed well the fall rains usually carry on the growth. Planting for what may be called the second run of new potatoes requires stricter attention to thermal conditions. This crop must be growing in December and January, which are our months of heaviest frosts and rainfall usu- ally. Strictly thermal belts, to be found at different ele- vations on hillsides, generally within the reach of ocean influences in the south half of the California coast line, but also here and there on the hillsides of the interior, favor the growth of the potato all through the winter, if the soil be light and kept warm by free escape of surplus water and abundant winter sunshine. The third run of new potatoes is secured by the plant- ing of the early varieties as soon as possible after the heaviest frosts of the locality are over, and the soil be- comes warm enough to push growth. This is the main po- tato planting season of California, and covers a wide range of dates, beginning with January on light, well-drained soils at the south to get the earliest new potatoes for East- ern shipment in May ; proceeding in February, not only in the south, but on warm uplands all through the central portion of the State, and continuing with planting all through March, April, and May, as favoring soil condi- tions come successively to the upper coast valleys and the mountain regions, or as the river lowlands and reclaimed islands are drained of their surplus water. In fact on in- terior river lands planting may be done as late as June and July and the crop comes on rapidly with ample heat and ALWAYS PLANTING POTATOES. 319 moisture producing the first new potatoes of the California garden year, as previoiisl.y stated. Thus it appears that potato planting covers the entire year, and that while some parts of the State are digging their main crop, other parts are making their first planting. To bring the matter nearer to a point it may be said that a man in the central coast region may be eating new potatoes from his hillside while he is planting his main crop on his lowlands. And yet one is frequently asked to answer categorically the question: "When do you plant potatoes in California?" Obviously it is a local question, to be learned by experi- ence, observation, and inquiry, in accordance with the general conditions outlined in the chapter on the planting season in California. In connection, however, with this wide liberty in plant- ing, taking the State as a whole, it must be borne in mind that local requirements are sometimes very sharp and that planting on the interior plains or in other parts of the State where there is high heat and drought, or the soil be- comes dry even with moderate heat, planting must be un- dertaken early enough to allow a large part of the de- velopment of the plant before such stress comes. Local failures with potatoes may, therefore, be often attributed to neglect of planting as soon as moisture and temperature conditions favor growth in each locality. Soils.- — ^Light, rich loams are best for potatoes as they favor root extension and expansion of tubers and they are retentive enough to hold the moderate amount of moisture which ministers to the highest quality. Very near the coast well-cultivated, light uplands receive atmospheric moisture enough to sustain the deep verdure of the potato fields, while the pastures are sere and yellow. Summer growth on interior plains and foothill slopes and mountain plateaus is sustained by less irrigation than many other crops require, and winter growth, whenever feasible, is best on light, free soils. The sediment and peat of the river lands are also, in their season, light and warm. But the potato insists upon adequate moisture, though its claim 320 CALIFORNIA VEGETABLES. is moderate. It cannot give satisfaction unless its mois- ture requirements are met. Heavy soils in garden culture can be greatly improved as described in the chaj)ter on Vegetable Soils of Califor- nia. Early and deep working of the soil and Uk; plowing in of rotten straw and compost and thorough mixture of these materials through the soil will have marked effect, but heavy land potatoes seldom have the beauty and flavor of th(^ product of the light, rich loams. Culture. — Deep working of the soil is essential in pre- paration for potatoes as has already been urged for beets and other root crops. The soil must be made mellow to a good depth by at least two plowings and kept mellow by subsequent cultivation. Unless the seed potatoes are old and show active eyes, they should be exposed to sunlight for several weeks to advance germination. This is especially the case when the tubers of an early crop are used for later planting the same season. All proposed methods of seed-cutting have been tried in California, and each has its advocates. When the soil and season favor, excellent crops are grown from small po- tatoes used as seed, but generally the selected fair-sized, 2nerchantable potatoes, cut into quarters lengthwise, pro- duce best results. Cutting should not be done too long before planting, to guard against too great drying of the seed. Recently machines for seed potato cutting have been used with satisfactory results by large planters. Dis- tance between pieces in the farrow depends upon the ten- dency of the potatoes to grow too large. This is often corrected by dropping more thickly. The range is from 12 to 20 inches usually. In the field much planting is done with the plow by dropping the "seed" in every third or fourth furrow, so as to bring the roots about three feet apart, and covering with the following furrow. Depth of planting depends upon season and soil as described on page 158, the same principles governing as in the planting of seed. After the POTATO GROWING. 321 seed is plowed in to a depth of four to eight inches, ac- cording to season and soil, a thorough cross-harrowing should leave the field in good shape. On light soils dis- posed to be dry, a light rolling may be beneficial. As soon as the plants appear harrowing with the rows mellows the surface, kills small weeds, and does not hurt the potatoes. Cultivation between the rows should follow when the plants are up about three inches, and the surface should be kept loose until the plants are quite high. Good, clean culture is the rule with potatoes. In some soils, not dis- posed to dry out too rapidly nor to crust, crops are often made with little cultivation after weeds stop growing, especially where the plant has the benefit of coast influ- ences, but cultivation for moisture retention, where needed, must be more thorough. On lands subject to excess of moisture, winter growth of potatoes can be facilitated by the ridge planting described in the chapter on Cultivation, but where this is not likely to occur, flat culture is best, both in winter and summer. Where potatoes are to be irrigated a slight moving of the soil toward the row, so as to make the interspace a little hollow to carry water, is admissable, but "hilling up" is unnecessary and dangerous. It usually uncovers the firm soil and exposes the roots to too great heat and drought. It is also likely to bring the tubers within reach of the moth from whose eggs come the potato worms. During the latter part of the growth the tuber should be well cov- ered with soil. Irrigation.— The potato should be kept growing thriftily from start to finish. If growth is arrested by drought, a new growth of small potatoes is apt to start upon renewal of moisture, to the detriment of the crop. The aim should be, then, to keep the soil adequately moist by constant cul- tivation or by irrigation until maturity approaches. Irri- gation is best done by running small streams between the rows, the planting having been arranged for this distribu- tion. As already stated, excessive irrigation is decidedly detrimental to the quality of the crop, and extra effort 322 CALIFORNIA VEGETABLES. must be made for even distribution of the water. To allow low places to fill up with water is injurious and to allow the water to come in contact with the plant stems is also dangerous. A good, thorough, and uniform wetting of the soil is often enough to finish the crop and it is seldom de- sirable to irrigate after the bloom appears. Thorough sur- face cultivation should quickly follow the irrigation, for the reasons stated in the chapter on that subject. Mulching. — For the last 35 years the practice of groov- ing potatoes on the interior plains by the help of a straw mulch has been followed to some extent. It has recently been proposed at the east as a new method, but it is really quite old. The seed is plowed in with a shallow furrow so as to cover about three or four inches, then cover the whole surface with partly decayed straw from an old stack or with coarse manure. The mulch will retain moisture enough to mature a crop. There need be no plow- ing, hoeing, nor weeding, and it is held by those who ad- vocate the method, that the labor of putting on straw is compensated for the saving of hoeing and weeding. It is also a safe way to grow early potatoes in frosty places be- cause the mulch protects the dormant buds at the base of the stems and new foliage quickly grows if the old is nipped by frost. Harvesting. — Potato diggers or plows are used to some extent in California, but the common method of gathering is by means of a long-handled shovel which is dexterously pushed beneath the plant so that all the tubers are thrown out at one operation. The yield of potatoes varies from five to nine tons per acre on good soil, properly cultivated. Storing. — As the summer and fall climate of California is almost rainless and the frosts seldom severe enough to freeze a potato in a sack, the tubers are generally sacked and piled in the field for weeks and months. This advan- tage is turned by careless growers into a disadvantage, be- cause the potatoes are often seriously injured by heat and light and shriveled by dry, hot winds, or the moth places her eggs upon them and wormy and worthless potatoes is POTATO VARIETIES. 323 the result of her work. Potatoes shoukl be stored in a dark, dry place and protected from heat. If left in the field for a time the piles should be covered with boards, straw or canvass. Varieties. — As with other vegetables, California has tried many kinds of potatoes and grows very few on a commercial scale. The first notable varieties were brought from Chili and Peru in very early days, and are still grown in a small way though the main crop is now made of newer kinds because in some localities the old varieties ran out and showed great susceptibility to blight. The blight, which in some years is a serious menace to potato growing, has been partially escaped by the introduction of new varieties which were thrift.y, while the old varieties on adjacent ground perished. For this reason new varie- ties should be tested in all localities. The potato which constitutes most of the market crop is the Burbank and some variations of it are locally popular. For mid-season and late potatoes nothing compares with the Burbank. For early potatoes the old Early Rose still prevails widely though others are encroaching upon it. Triumph is a little earlier and is gaining ground. Early White Rose, Early Clark and Early Ohio are chiefly popu- lar in southern California. American "Wonder, and Snow- flake and Pearl are advancing as shipping varieties and Peerless still retains favor in some localities. Although there are local adaptations of different va- rieties, the character of the potato depends more upon local conditions of soil and climate than upon the variety and the same variety from different localities commands widely different prices in the market. SWEET POTATOES. The sweet potato is grown in nearly all parts of Cali- fornia where rich, sandy loam, suitably moist, can be found. Adequate heat is essential to quality and the upper coast region has localities which are deficient in this re- spect, but protection from coast influences renders the pro- duct satisfactory, even though distance from the ocean be 324 CALIFORNIA VEGETABLES. not great. As a rule, however, the crop in the upper half of the State is grown in the interior valleys, while at the south, both the coast slopes and the interior valleys yield a fine product. Where the soil is rich, warm, and free and the moisture sufficient, the sweet potato attains immense size and rightly ranks among the great things of Cali- fornia. The sweet potato is a strictly tender plant and a heat- lover as well, consequently there is no winter planting, though in drier parts of the State, free from frost, there may be fall plantings which carry their crop well into the winter and for more than half the year fresh potatoes may be taken from the ground, and by proper storing the vege- table may be enjoyed throughout the year. Preparation of the Ground. — Planting is done at the be- ginning of the frost-free period and the date depends upon the locality. Usually it comes about the first of May, but preparation of the ground should begin earlier to secure good culture and moisture retention as described for other root crops. In regions of good rainfall moisture enough can thus be retained to make the crop, or at least start it well. On dry plains it may be necessary to thoroughly irrigate in the spring before the deep plowing with which the planting is to be made. On loose, lowland soils or in irrigated regions there is often abundant moisture within reach of the plant to serve its purposes and then sweet potatoes may follow a hay or grain crop just as in the practice with common potatoes. Lands which receive moisture from below, and yet are not wet and cold, pro- duce the crop with least labor and expense, though it is quite feasible to proceed with direct irrigation both for planting and after growth. The sweet potato sends its roots to great distances to find moisture. Growing- the Plants. — The sweet potato grows readily by cuttings from the growing vine planted out directly in the field if the ground is moist and warm. This method is followed to rapidly multiply a rare variety. The usual method is to plant the crop by using sprouts from potatoes SWEET POTATOES. 325 on which growth is quickly started with bottom heat. Any of the hot-bed appliances described in the chapter on propagation may be used for this purpose on a small scale, but in the warmer parts of the State it can be done on a large scale for field planting without expense of glass or cloth covering. There is, however, often advantage in an early start with sweet potatoes, and for this the plants must be started when air and soil are too cold. Hot water circulation is being used for bottom heat. If artificial heat is used, care must be taken against overheating. To grow plants in the open air, dig a trench four or five feet wide and about two feet deep ; the length according to the number of plants desired. The trench should be dug in light, well-drained soil, in a place protected from cold winds, such as the south side of a building. Put in fresh horse manure and tramp down until about a foot and a half of thickness is secured. Wet it well, but not enough to drain, and immediately cover with three or four inches of moist soil. Upon this place the sweet potatoes just as close as they can be put down without touching each other. When done, sift in fine sand between the potatoes and finally cover with three inches of very sandy loam, or even with sand. Keep this bed moist but not wet. Moisture and heat may be retained by covering the bed with two inches of loose straw to be removed as the shoots appear. The plants are ready for use in about eight weeks from the bedding of the tubers, when they show a few green leaves; they can be detached by pulling and will bring their outfit of small roots with them as they are pulled out of the sand. The tubers will then send up other shoots which can be used for later plantings. Some prefer to uncover the potatoes, beginning at one end of the bed, removing the shoots and replacing the cov- ering. This lessens the danger of breaking the shoots. Others split the potatoes lengthwise and plant with the cut side down so that all the shoots come from the upper surface, and are thus less liable to break in pulling. Planting. — Most sweet potatoes a.re grown on ridges to 326 CALIFORNIA VEGETABLES. secure greater heat in the soil and to facilitate irrigation, but flat culture is also practiced, and in some regions is decidedly better. After the land is well prepared and harrowed down smooth, mark off the rows three feet apart and set the plants eighteen inches apart in the row. AVhen the ground is thoroughly warmed by the advance of the season, say in April or May, take the shoots as described above. They must, of course, be kept from drying out, the young roots being very tender. In taking them to the field they must, therefore, be kept in a bucket with water, or in a wet sack, the former being the best. Plant out the shoots eighteen inches apart in the rows, one in a place, settling them down in the soil deep enough to find permanent moisture. Sometimes when the object is to get unusually large potatoes, instead of pulling off and setting out the slips, the potato is lifted out, and with every slip a small piece of the potato is cut out and planted with the slip. This method will bring the earliest potatoes, but the number of sets are many less than though the potato be allowed to remain in bed for their continued production. Recently planting out with a machine has come into use, such as the transplanting machine, which digs a trench on the top of the ridge and drops water at whatever intervals are desired. Two boys place the plants, holding them until the machine draws the dirt securely around them. Ctdtivation. — Cultivation for the purpose of weed kill- ing and surface stirring is continued until the vines inter- fere, and after that the vines cover the ground with a thick mat and discourage weed growth. Harvesting and Storage. — Use of the sweet potatoes may begin when they attain suitable size, but for keeping they must attain a good degree of maturity. Some find the keeping of sweet potatoes somewhat diffi- cult. Many pack the potatoes in dry sand and keep them in the house. This is expensive and is not a sure way. Many will rot, and sometimes only one-third of them will keep till spring. Storage in the open air with due pro- KEEPING SWEET POTATOES. 327 tection against too great temperature changes and moisture is better. This method has been approved in Fresno county: Take stout stakes, say five to six feet long, and drive them into the ground in a row and five feet apart, in some dry place that is not sheltered by trees. Dig the potatoes and throw them up around the stakes to the height of four feet. For a large field a great many such rows may be necessary ; for a small patch perhaps one single stake will suffice. When all dug, put four inches of straw as cover- ing. After a week or ten days, according to the weather, the potatoes will have undergone a sweating process. They first cover themselves with moisture, as if they had been dipped in water. This moisture gradually begins to disappear, and as soon as it does so it is time to throw off the straw. This should be done when the wind is blowing ; the potato hills should be left open for three or four hours, or until the potatoes appear entirely dry. If the straw covering is taken off in the morning, the potatoes will be dry at noon. Then cover them again with three or four inches of fresh, dry straw, and on the top of the straw put three or four inches of soil to keep out the cold. On the top of this must be placed a roof, which is easily made of shakes nailed to strips of two by three and made in the shape of panels, to allow of easy handling and of repeated use year after year. Potatoes kept in this way will pre- serve perfectly until next spring. Very few, if any, will be found decayed. Varieties. — Probably all the improved varieties have been introduced in California. The California demand is for a variety which is rather dry and mealy when cooked, although the softer, sweeter sorts have some advocates. The most common variety is called the Californian, but it is a Chinese sort introduced in early daj^s. The Southern Queen and the Nansemonds are also popular and the Jersey Red is grown to some extent in southern California. CHAPTER XXIX. RADISHES. The Radish. — Baphanus sativus. French, radis; German, radies; Dutch, radijs; Danish, haverdoedike ; Italian, ravanello ; Spanish, rabanito ; Por- tuguese, rabao. Horse-radish. — Cochlearia A rmoracia. French, raifort sauvage ; German, meerettig ; Dutch, peperwortel ; Danish, peberrod ; Italian, raf ano ; Spanish, taramago ; Portuguese, rabao de cavalho. The radish is a relish which can be had continuously throughout the year in most parts of California, if proper soil and moisture conditions can be arranged. It is almost a hopeless task to undertake to secure a crisp, delicately flavored radish unless heat and moisture are favorable to quick growth of the plant. It takes some gardening skill, therefore, to produce good radishes in winter localities with sharp frosts and heavy rainfall, while in regions of light frost and light rainfall, winter heat is usually ade- quate to satisfactory growth. The best soil for radishes is a rich, sandy loam, though any good garden soil will grow them if a small piece is improved for the purpose as described in the chapter on Vegetables Soils of California. Preparation of the soil is essentially the same as that already described for other root-crops, and sowing, as already intimated, can be done whenever the soil is in good condition, if irrigation is available for use in the dry season, and there is free drainage in the winter. Tempera- ture is, however, of more moment to the radish than to some other hardy garden plants, and during the colder months, the raised bed, as previously described, located GROWING RADISHES. 329 on the sunny side of a wind-break, will afford heat enough usually. In other places where cold and rain are greater the "warm heap" described elsewhere may be used. By thus adapting the method to local conditions winter growth can be had anywhere in the valley and foothill re- gions of the State. Summer growth is mainly a question of soil-moisture Avhich can be regulated by irrigation and cultivation. As the radish is naturally of quick growth and as crisp- ness and mild flavor are largely conditioned on pushing it to the utmost of its speed, it can be grown to advantage as a catch crop here and there in the garden on ground that is temporarily out of use for a few weeks, or between the rows of more slowly growing vegetables. The gardener should alwaj^s be ready to scatter good radish seed when he has a little stretch of light, rich, moist soil at command. A little attention and ingenuity will in this way secure a constant supply. Varieties. — Popular favor runs in the direction of the turnip-shaped varieties, of which there are very many The long radishes are, however, often chosen for home use. The Early Scarlet Turnip is most largely grown and there are several strains of it varying in earliness and color. The E^'rench Breakfast, oval, tipped with white, stands next to the Scarlet Turnip sorts, and the White and Scar- let globes are Avidely grown. The Italian market garden- ers grow what is knoAvn as the "Half-Long," a variety of Rose Olive-Shaped and the Black Spanish, very desir- able for winter growth. The White Turnip, similar to Scarlet Turnip except in color, is popular with German gardeners, and the Chartier has some popularity as a large scarlet variet.y, shading to pink and thence to white at the root-tip. The Crimson Giant turnip is very large and yet generally solid and crisp. The Mammoth Chinese dis- tances all others for size. It is pure white, mild-flavored and crisp, even though it may grow 18 inches in length and three inches in diameter in six weeks, with interior heat on light soil, abundantly moist. 330 CALIFORNIA VEGETABLES. HORSE-RADISH. Horse-radish is a popular relish in California and is bottled on <|nite a large scale. The plant is easily grown and shonld be found in every farm garden. A start is most conveniently made by planting root sets. ]\Ir. Ira W. Adams advises planting the roots or sets in rows two feet apart with the sets one foot apart in the rows, and three or four inches under the surface. On rich, moist soil, with the best of cultivation, one can raise roots that will weigh from one-half to three-quarters of a pound. When the roots are dug in winter for use, break off all the small rootlets from one-quarter to one-half inch in diam- eter, cut into pieces from three to five inches long, leaving the top end square, and the bottom end slanting, so there will be no mistake in planting them upside dowm. Tie in small bunches and put into moist sand that has perfect drainage and is exposed to the weather. In very cold, long, heavy rains it is w^ell to cover with shakes, or short pieces of boards. A cool cellar is a good place to store them, but be careful that the sand is never allowed to get dry, as the sets will not root nicely without continual moisture. Early in the spring there will be nicely rooted sets ready for transplanting, as before described. CHAPTER XXX. RHUBARB. Rhubarb or Pie Plant. — Rheum sp. French, rhubarbe ; German and Danish, rhabarber ; Dutch, rabarber ; Italian, rabarbaro ; Spanish and Por- tuguese, ruibarbo. Rhubarb attains grand size and quality in California if due attention is paid to the requirements of the plant, and it should have a place in every house garden. It enjoys very rich soil and will thrive on a great variety of soils, even from heavy clay to light peat, providing ample mois- ture is afforded it. On heavy, retentive soils it must have good cultivation or thick mulching to prevent loss of moisture and surface baking : on light, coarse soils either ample irrigation or natural sub-irrigation will keep the plant thrifty and vigorous. It does not enjoy high heat and drought, and the old varieties reach best estate and are chiefly commercially produced in the coast valleys or on the river bottom lands of the interior, but can be very satisfactorily grown for home use on interior plains and mesas providing constant moisture is supplied ; partial shade is also grateful to the foilage in the interior, but is not necessary on the coast. Since the wide introduction of winter growing rhubarb, which defies the frost and en- joys the ample moisture of the rainy season, the range of the plant has vastly increased in California and its com- mercial importance has greatly advanced. Culture. — Rhubarb is grown from seed or propagated by division of the roots: the latter insures reproduction of the identical characters of the parent, while from seed there is always a chance of variation. Rhubarb plants may be grown from seed by preparing 332 CALIFORNIA VEGETABLES. the ground in the same way already described for aspara- gus, and the same care of the seedling as there indicated will bring good, strong rhuliarb roots for planting out as yearlings. Mr. Ira W. Adams gives the following special advice for rhubarb seedlings : Prepare the bed the same as for asparagus. Sow the seed in rows one foot apart, and one inch apart in the row in a little furrow one inch deep ; tamp down lightly with the back of a steel rake and cover with the finest of soil, as the seeds are small and light. When the plants are an inch or two high, they can be transplanted into rows 12 inches apart, and four inches between the plants. By fall they will be fine, strong plants, and can be planted out the next spring in permanent rows. Root sets are made by dividing the roots of the older plants so that each piece shall have a bud or eye. The most vigorous plants, producing the largest leaves and thickest leaf-stems, should be selected for this purpose. Planting. — Before planting either in field or garden the soil should be heavily manured and deeply turned in the fall so as to get the full benefit of the winter rains. Trans- planting of the old varieties should be done when the plant is dormant, the soil in good working condition and warmth enough for growth anticipated. The date will, of course, vary in different localities, but February will usually be satisfactory for the summer growing varieties. The soil must not be too wet at transplanting or the roots may rot : good warmth and moisture are favorable. The introduction of winter growing varieties has modified transplanting practice. They are practically evergreen and active except for a short dormancy in the late sum- mer, and, though capable of transplanting by cutting back the leaves all through the rainy season, are usually moved the best advantage from April to June, the latter period being available on irrigated land. There are different ways of planting out, each with its own advocates. Roots set four feet apart each way give good opportunity for cultivation both ways: but some GROWING RHUBARB. 333 give more room by laying off in six feet rows with the plants three or four feet apart in the row. Others plant in the garden, placing the plants two feet apart, if only one row is planted, and in four feet rows with the plants three feet apart if there are to be several rows. On good, strong, deep soils, it is well to give plenty of room, for large growth of leaves is desired to impart vigor to the roots. Distance depends somewhat upon the variety, but nearly all growers aim at very large leaf stems, and these require ample space. Treatment. — Plants of summer growing varieties should be allowed to retain all their leaves the first year after planting out, and there must be abundant moisture for summer growth if there is to be a heavy crop the second year. Frequent summer cultivation is desirable unless mulching is employed, and if it is, the grower must be sure that his mulching is heavy enough to retain moisture. It is probably better to trust to cultivation and irrigation in most situations. With the fall rains the surface should be liberally dressed with manure and covered in as deeply as possible without injury to the roots. Shallow cultiva- tion should follow before the weeds advance too far, to be repeated as necessary to keep the field clean. Winter growing varieties, planted out in the spring and summer, irrigated, establish themselves so strongly the first summer that some pulling can be done upon them the following winter. Even without irrigation, spring set plants will receive a new impulse with the first rain, grow riotously with the autumn heat and give large leaf stems by the holidays in the warmer parts of the State. Manuring and cultivation should be followed year after year to keep the soil rich and in good tilth. Some soils are, however, so rich naturally that such liberal manuring may not be necessary. The plant should not be too fully stripped of its leaves nor should the pulling be continued too late in the summer. The following crop depends upon adequate leaf action — consequently the plant must have foliage and summer moisture to maintain it. 334 CALIFORNIA VEGETABLES. Varieties. — The Moiiai-ch is larj^ely grown. It has a very wide, fiat stem. The Victoria has red, long stems, rather sharp acid, but a very productive sort and popular. Lin- naeus is early, large, thick stems, of excellent flavor and less acid. The Crimson Winter, introduced from Australia by Lu- ther Burbank about 1895, and sold by him to the trade in 1900, has revolutionized rhubarb growing in California by completely reversing the market season. This variety and its improvements by Mr. Burbank and by others who have practiced selection since he sold it out, has multiplied the rhubarb acreage of the State and vastly increased the ser- viceability and commercial suitability of the plant. It has precluded forcing in California and promises to render forcing unprofitable even in the wintry parts of the coun- try because of the large supplies of open air rhubarb which are available for shipment from this State at all times of the year when the summer varieties grown in wintry cli- mates are unproductive. CHAPTER XXXI. SPINACH. Common Spinach. — Spinacia ohracea and spinosa. French, epinard ; German, spinat ; Dutch, spinazie ; Danish, spinat; Italian, spinaccio ; Spanish, espinaca ; Por- tuguese, espinafre. New Zealand Spinach. — Tetrayoiiia expansa. Spinach is an all-the-year- plant in California, and the house-gardener need never fail to have tender foliage for boiling if he arranges for successive sowings and knows the varieties and species which befit the changing seasons, for he can choose for fall sowing that which is perfectly hardy and thrifty in the California winter, and for spring sowing that which will furnish succulent pluckings even through the heat and drought of the interior summer. But though this is so, it is chiefly as affording winter greens that spinach is grown for the market. The summer fur- nishes so large a variety of table vegetables that it is chiefly in winter that the housewife turns her attention to pot-herbs. Culture. — The varieties of common spinach (spinacia) dislike heat and drought and enjoy moist, rich soil and moderate temperature. These conditions are afforded by all California gardens in the winter, providing the grower will heed the suggestions for ridge-culture, etc., given in previous chapters, for escaping surplus water and secur- ing suitable growing-temperature in the winter garden. With these provisions it is easy to secure winter spinach by following the suggestions given for the winter growth of lettuce, peas or other hardy vegetables. What has been said of fall sowing of these, applies also to spinach. The plant makes best growth from seed sown in place, and if 336 CALIFORNIA VEGETABLES. the seed is good it m;iy be thinly sown, for the plants should not be allowed to crowd each other. They should have from six to nine inches space in the row and should be kept free from encroachment of weeds. To keep the soil from packing by rains, and to push the plants as well, a top dressing of fine manure may be placed to be leached out by the rains. In a garden with permanent walks, spinach may be sown as a border plant, which brings it within easy reach for the frequent plucking of leaves. The plants will endure this, and by means of new growth on old plants and successive sowings, it is feasible, as above stated, to have spinach always ready. The variety chiefly used is the "Large Prickly," although the "Long Stand- ing" is also esteemed because of its long leaf growth be- fore sending up seed stems. The Round or Summer is also considerably used. For greens in the hot and dry summer and dry autumn, the New Zealand spinach is making a fine record in Cali- fornia. It has been widely distributed by the State Uni- versity. Even in interior situations it grows on dry ground all summer, and maintains rich green color until frost kills the top growth. The stems and foliage are very sensitive to frost, but the root is more hardy and gives new growth and is useful in the spring. The plant sends out shoots of considerable length which may be cut off for cooking. Its tenderness and flavor are vouched for by many growers. Early summer cutting may be had by starting plants with bottom heat and planting out like egg plants, but in our long summer, sowing in the spring after frost danger is over, gives abundant foliage in late summer and autumn. CHAPTER XXXII. SQUASHES. Mammoth Squashes or Pumpkins. — Cucurhita maxima. French, potirons ; German, melonen-kurbiss ; Danish, eentner-groeskar ; Italian, zucca ; Spanish, calabaza to- tanera. Marrows and Scollops. — Cucurlita pepo. The species moschata also contributes same horticultural varieties. The California-grown squashes are all noted for pro- digious size and the acre-product is also immense. Squashes have been used from the early days as exponents of size in California vegetables, at all distant and local exhibi- tions, and the statistics thereof would fill a volume. Weights of single specimens have been attained in excess of 300 pounds, and field crops above 30 tons to the acre. To avoid exaggeration and at the same time present the truth about the California squash in a picturesque man- ner, a single record is presented from the writer's collec- tion of cucurbitous literature. Philander Kellogg, of Go- leta, Santa Barbara county, who is personally known to the writer as a man of truth and probity, furnishes this statement : I planted my squashes in May, and harvested them in October. Finding that they were unusually large, I weighed 10 of the largest and found that their aggregate weight was one ton and 50 odd pounds, the largest one weighing 225 pounds. This squash was exhibited at the county fair and received the first prize. On the 15th of November, which was my boy's sixteenth birthday, I cut open one of the other squashes, that weighed 210 pounds, and took out the seeds ; my boy then got into it and I put 338 CALIP^ORNIA VEGETABLES. the picc(' together riiul eonipletely closed him in, the parts coming tight together. I then persuaded my eighteen- year-old daughter to get into it and I closed her in, in the same manner. My daughter's weight was 110 pounds. I then put two seven-year-old boys in at once. I then put my three little girls in at once ; they were aged respec- tively six, four and two years, their united weight being 116 pounds. I placed the largest child in the bottom and the little one on the top and then put on the lid; the squash was cut so that the top could be easily put on or removed. The squash was three feet four or five inches in length. The growth and productiveness of the plant in specially favorable places are proportional to the size of the fruit : vine growth of 50 feet and from 30 to 42 good sized fruits to the single vine are recorded — a good wagon load to the vine. Localities and Soils. — The greatest specimens and the heaviest crops are produced on rich, retentive loams. These are rather heavy soils and are usually the lowlands of either coast or interior valleys. But great squashes are not confined to such soils. Lighter soils, if abundantly rich and adequately moist, are also very satisfactory, and in fact any good soil deeply plowed and properly culti- vated, until the vines cover the ground, may be expected to give good return. For this reason the dairy farmer who has suitable land, grows squash in large quantity for fall and early winter feeding ; the mixed farmer enters squash as a stated item in his list of crops, and the fruit farmer is quite apt to grow squash between the trees in his young orchard, to contribute to his family milk supply. The squash is somewhat exacting in its moisture supply, and does not respond well on light, dry soils unless irri- gated. With enough moisture the plant endures the high- est interior heat and records large production. Excessive irrigation is, however, to be avoided, for it is apt to di- minish the fruiting. X m < a m Q 340 CALIFORNIA VEGETABLES. Culture. — The squash plant is very tender: it is de- stroyed by frost, and the seed is apt to fail in cold ground. The proper practice is to have the soil previously well cul- tivated, but to delay planting seed or transplanting seed- lings from the covered bed until the time is frost-free and the soil warm. The culture of the squash is therefore like that already prescribed for the cucumber and for melons, in the chapters devoted to those subjects, to which the reader is referred. The bush varieties of squashes follow the cucumber in distances, and the running varieties fol- low watermelon distances. There is, however, some dif- ference in the practice of growers of the running varieties : some advocate rather close planting, as six by six or eight by eight feet in squares, and others plant at wider dis- tances, even to setting two plants in a place at intervals of 14 feet apart. It is impossible to state any specific dis- tance at best : it is to be determined locally according to the growth which the local soil and climate produce. One is apt to err on the side of crowding than otherwise. Care must be had not to cover the seed too deeply. It must be firmly placed in moist soil and covered enough to avoid quick drying. The suggestions in the chapter on propagation are as definite as they can be made, accord- ing to the character of the soils employed. Cultivation must be begun as soon as possible after planting, to save moisture from loss either by weeds or evaporation, and must be frequent for the same reason. Nothing looks more distressful than squash vines perish- ing on baked clay or dry sandy soil which, if properly cultivated from the start, would have sustained a splendid growth. Garden Culture. — In addition to injunctions for thorough working of the soil and adequate irrigation, there is the opportunity in garden culture to produce grand results by special fertilization. Careful use of the compost or liquid manure, described in the chapter on fer- tilization, produces marvelous results. SQUASH GROWING. 341 Varieties. — -We have in California probably all kinds of squash known to horticulture. Some amateurs take special interest in such collections, and scores of varieties repre- senting the whole gourd family have been shown in State fair exhibits. And yet the bulk of the product is made of very few varieties. Of the bush forms which are relied upon for summer squash, the scollops comprise most of the crop, both the early white and yellow being grown — the former pre- ferred. The yellow crook-neck is also grown to some ex- tent. The Italian and Boston marrows have a few warm advocates. Of the winter squash for table use, the Hubbard and the Red or Golden Hubbard, which is a little earlier, are chiefly grown. The field squash crop is made of several varieties. The California Marrowfat, a splendid, orange-colored squash, takes the lead, while associated with it in the same field may be found the Mammoth Chile, which is usually the sort, more or less pure, which yields the largest speci- mens. There is also a very large winter crookneck, very prolific and rather more hardy in trying situations, but not so good in keeping quality as the preceding. Here and there may be found a field of the old-fashioned New Eng- land pumpkin, and fair exhibits usually bring to light both the Etampes and Tours pumpkins, but the large orange and light olive fruits are named squashes in the California vernacular, and are preferred. There is much confusion both in the terms "squash" and "pumpkin," and there are many chance hybrids which await analysis by some cucurbitous specialist. CHAPTER XXXIII. THE TOMATO. Tomato or Love Apple. — Lycopersicum escuhntum. French, German, Spanish, and Portuguese, tomate; Dutch, tomaat; Italian, pomo d'oro. The tomato is one of the most popular, prolific, and profitable of California vegetables. It is grown every- where during the local occurrences of the frost-free period, and in our thermal situations the fruit can be gathered all the year. The earliest fruit in our local markets and the earliest shipments to the East are gathered from vines which have continued growth from the previous summer and autumn, and, encountering no killing frost, are able to fruit through the winter months. Favorable places near the coast in southern California are best known for this winter crop. The winter-grown fruit is, of course, in- ferior to the summer and fall crop, though it is excellent enough to command high prices for table use until the earliest yield from spring plantings is to be had. When this new crop comes in, the fruit from the hold-over plants becomes cheaper, but is still marketed until the new crop becomes abundant. In this way one year's plants in southern thermal situations lap over upon the yield of the following year in the earliest interior sections at the north, and the tomato supply from open air plants is continuous through out the year, though the supply regions are hun- dreds of miles distant from each other. The fact that the north produces earlier spring tomatoes from new plants than in the south is difficult for distant students to realize. It is conditioned upon ocean influences and local topog- raphy, which at the south prevent frosts which winter-kill the old plants at the north, and at the same time postpone CONDITIONS FOR TOMATOES. 343 spring heat at the south, which is attained earlier in shel- tered places in the interior at the north from which ocean influences are excluded. There are places in the interior at the south, east of the high mountain range, which are furnishing tomatoes earlier than either the southern coast or the northern- interior. Still, in the all-the-year demand for the tomato, it is necessary to bring some fruit from Mexico and from the forcing houses of the Southern States, and it is probable that more forcing of tomatoes will be undertaken in this State in the fuutre. No vegetable has advanced so rapidly in public esteem during the last decade as the tomato. Requirements of the Tomato. — For early tomatoes which can attain their chief growth before the close of the rainy season, somewhat elevated situations, above the lowland frosts, and with light, warm soils and free drainage, should be selected. Sometimes frosts will occasion replanting, for which a stock of thrifty plants should always be in readi- ness. It is idle to attempt the growth of early tomatoes on a commercial scale except on situations naturally fitted for them. In the family garden, however, slight covering from frost can be successfully undertaken. For the main crop of tomatoes, rich, lower lands, either naturally retentive of moisture or supplied therewith by irrigation, are usually employed. Even heavy valley soils are profitably used by thorough preparation before plant- ing and cultivation afterward. Late planting can be prac- ticed and immense yields are secured for harvesting in September and October, when the fruit is of superior solidity and the canneries are clear of their summer fruit work and can turn their full capacity to this most popular canned vegetable. In some parts of the State, November and December tomatoes are very profitable when autumn frosts and rains are light. The moisture requirements of the tomato are moderate, but they must be adequately met. Stunted vines and small, inferior fruit are the results of drouth. High heat can be endured and favors growth, provided ample 344 CALIFORNIA VEGETABLES. moisture is available. The more moderate heat of the coast regions and the interior river bottoms is, however, ade- quate for full development of the plant, and it is attained with much less moisture than on the higher lands of the interior. For this reason splendid crops are secured with- out irrigation on retentive soils in valleys of sufficient rainfall, even if the plants are not set until the opening of the dry season — provided suitable winter and spring working is given to prevent evaporation and to hold moisture near the surface. On lands moistened by under- flow splendid tomatoes can be grown without irrigation all through the local frost-free period. Plants for the Garden. — Tomatoes are readily grown from seed and the best plants are those produced with moderate heat. They need simple protection from cold rather than forcing heat, as our day -temperatures from February onward are almost always adequate. For earlier starting of plants some bottom heat is desirable and can be profitably used if care is taken for free ad- mission of air and subsequent hardening of the plants by later growth under protection but at lower temperatures. The considerations urged in the chapter on propagation for the handling of seeds and seedlings have special ap- plicability to the growth of tomato plants. For the home garden in the central and northern valley regions there is perhaps no better way of growing plants than that of Ira W. Adams, as follows : "Plant the seed about the middle of February in a small box two inches in depth, and keep in the house by a south window in a moderately warm room. On warm, sunny days, put them outdoors, and let them remain out day and night whenever the weather is warm enough ; in this way they will make stocky plants and be much hardier than if raised altogether in the house. The soil should be rich and mellow, and always kept a little moist. When the plants appear, thin out to an inch apart. As soon as the plants begin to crowd each other, transplant to another box about four inches in depth and give them a space of TOMATO SEED BEDS. 345 four inches. By the time they crowd each other again they can be transplanted outdoors on the south side of the house or barn into a good-sized bed of rich soil. Here they can remain until they get to be large, strong, hardy plants, with very large, fibrous roots. When all danger of frost is over, take a sharp spade and cut out a square of dirt with each plant, put into rows six feet apart, with BEDS FOR GROWING TOMATO PLANTS IN IMPERIAL VALLEY. the plants the same distance in the row. Plants can be transplanted in this way when over a foot high and in blossom. By transplanting them just at night, or on a cloudy day, they will hardly ever show a wilted leaf." Another way to secure large plants for garden planting is to start them in a seed box, in the house, or with bottom heat as described in the chapter on propagation, and then transplant, when small, into growing cases made of dis- carded fruit cans. Select those of similar size, throw them on a burning brush pile for a few minutes, when the 346 CALIFORNIA VEGETABLES. tops and bottoms will drop out, and the seams on the sides will open, leaving a smooth tin shell. Tie a string around each to keep it from spreading. Set them in a box or frame made of four boards. Fill the cans and the spaces between them with good friable soil, set a small plant in the center of each shell, sprinkle well and keep moist. When the plants are well grown they may be transplanted in the garden. Take the cans carefully out of the frames, grasping the cans firmly to prevent the plants and soil slipping out ; set them in a box or wheelbarrow and move them where wanted. Prepare the soil by working in a shovelful of well-rotted manure where a plant is to stand, but this is not required if the soil is rich. Dig a hole deep enough to set the upper rim of the can level with the ground, cut the string and fill up and press the soil firmly around the can, then by spreading the top of the can a trifle, it can be drawn out over the plants without disturb- ing the roots. If the weather is dry and warm, water may be used at transplanting — drawing loose soil around the plants after the water soaks away. Plants for the Field. — The above methods will produce plants of great size and vigor to delight the amateur. For a field crop it is hardly practicable to grow and handle plants in such an expensive way, and satisfactory results can be attained with much less labor. For late planting they may be grown in quantity in a cold frame with cloth cover or in a raised bed with slight protection from frost and sheltered from cold winds, or even on the open ground in frostless places. It is best to sow the seeds in drills, using the spaces between for cultivation and irrigation if needed, but many plants are often grown from the seed by simply thinning the seedlings as they stand, though the transplanted seedlings are always more thrifty and stocky. They have a much better root-system, and grow more thriftily after transplanting. Take the seedlings when they have come in the rough leaf, and with a small hard- wood stick, made pointed at one end, take up the young PLANTING TOMATOES. 347 plants and dibble them in clear down to the seed leaf. Place them about three inches apart each way, water them well, and in a few days they will begin to grow, and in this way fine, stocky plants can be grown almost ready to blossom when they are set out in the open ground where they are to remain. There is nothing gained by setting out tomatoes in the open ground when they are too small ; if anything, time is lost by doing so, while a large, stocky plant has plenty of fine fibrous roots, and is rapidly estab- lished in its new place. ' Tomato plants may also be grown from stem cuttings, as described in the chapter on propagation. Planting Out Tomatoes. — In addition to suggestions al- ready made for planting out, it should be remarked that for late planting especially, and in light soils, it is de- sirable to set the plants quite deeply in the soil. If the plants are slim and "leggy" they should be shortened, pruning off the laterals and most of the leaves to escape wilting, from which it is hard for the plant to recover. The rule with some growers is to set the plant half the length of the stem deeper than it stood in the seed bed, and in light, dry interior soils the stem has been entirely buried with good results. Depth of planting depends upon the character of the soil and its content of moisture. Where moisture is to be abundant it is better to have the roots nearer the surface. Preparation of land for tomatoes should begin early in the rainy season, as for beans, corn or melons, to render the soil absorptive of moisture and to secure good deep tilth. Re-working in the spring, and cultivation until it is safe to plant out the tomatoes, keeps the soil in fine con- dition, saves moisture and insures a crop at minimum cost. Crops are often grown on spring plowing alone, but it is an uphill task, and attended by great risk of failure, if spring rains are scant, as they often are. Field planting is generally done by hand, sometimes at the intersection of cross-markings, but often with less 348 CALIFORNIA VEGETABLES. care, by placing the plants firmly on the side of a fur- row and covering- with another furrow. Some large grow- ers use the transplanting machine mentioned for sweet potatoes, and it works well when the soil is in good con- dition. Distance depends upon variety. The usual distance is six feet apart each way, for the standard growers, but some plant more widely, even to seven and eight feet each way, and dwarf varieties are set at intervals of four feet. Summer Treatment. — Very seldom is any effort made even in garden culture to support the plant above the earth surface. As the crop is almost wholly grown Avith- out irrigation or with sub-irrigation by seepage from ditches, the earth surface is always warm and dry, and rot is almost unknown. The soil should be cultivated as long as it can be done without injury to the prostrate plants. Well-grown plants on rich soils almost cover the surface even when given the widest distances. It is commonly believed that excessive growth of foliage retards ripening and reduces fruitage. Whenever this oc- curs, as on very rich and moist interior soils, free cutting back of the plants with a scythe, is practiced with good results. Summer pruning of over-rank garden plants is also desirable, and may cause the fruit to set rather than drop in the blossom. Irrigation. — As already stated, the tomato abhors dry soil, and in some situations irrigation is essential. Care must be had against over-irrigation, especially in the coast region, where proper planting and cultivation will give satisfactory results with the natural moisture. Not only does excessive watering promote foilage at the expense of fruit which drops in the bloom, but it is apt to give a tomato which slices up into cart-wheels instead of firm and solid discs of flesh. Most growers cultivate too slackly, especially when irrigation water is used. Irrigation by flooding is sometimes successfully prac- TOMATO VARIETIES. 349 ticed, but application of water which does not wet the sur- face under the plants is preferred. Picking Tomatoes. — Tomatoes for shipping should al- ways be picked right. For such purpose the fruit should be picked when slightly blushed, not by squeezing or pulling. Encircle it with all the fingers and twist care- fully, leaving the stem on the vine, or rub it afterward, if it parts from the vine. Do not leave the stem end on the fruit. Pick in shallow boxes, not in deep pails or bas- kets, and use two receivers ; one for perfect fruit, the other for culls. Do not handle the fruit roughly, even if it seems very firm. Yield. — With all conditions favorable, tomatoes make a very large return. Twelve and a half to fifteen tons of marketable tomatoes have been gathered as an average per acre from large tracts in Alameda county. The largest specimen of which the writer has record was grown in Cal- averas county, with the following dimensions : circumfer- ence, twenty-two and one-half inches ; diameter at widest place, eight inches ; weight, four and one-half pounds. Mr. Ira W. Adams reports that he grew one year one hun- dred and thirty-six pounds of ripe tomatoes from one vine, and when the frost came picked thirty-four pounds of green ones. This vine covered a space of nearly eight feet square ; it grew on the edge of a ditch used for running water to blackberry vines. It was an instance of ample irrigation by seepage. Varieties. — California grows all the many improved to- matoes with which American seedsmen have enriched our vegetable list, and new varieties should always be looked for in California seedsmen's catalogues. They always offer choice yellow varieties for preserving. Varieties, which include those commercially most prominent, are as follows : Sparks Earliana : very earlj^ tall growing; fruit large, smooth, scarlet ; flesh deep red, solid. Chalk 's Early Jewel : nearly as early ; fruit large, 350 CALIFORNIA VEGETABLES. smooth, regular in form and ripening evenly; bright scar- let ; continuous bearing. Dwarf Champion : low growing, upright ; fruit medium, pink to purplish red, according to locality ; popular in the interior heat, especially at the south and in the foothills of central California. Stone : tall and fruitful ; fruit large, smooth, uniform, bright red, solid ; widely popular in southern California for market and shipping. A Dwarf Stone, resembling Dwarf Champion in growth is also a good shipping variety at the south. Boulder : resembling Stone, but much larger fruit : popular in the coast district of southern California. Ponderosa : a strong growing vine ; fruit very large, somewhat irregular and variable in color, usually light red ; flesh thick but not always firm ; chiefly grown in So- noma county for canning and market. Trophy : vigorous and productive ; fruit deep red, some- what irregular, solid and firm in the true type, with ring- mark at apex; chiefly grown for canning in Alameda county, displacing Stone. There is an opinion current among California growers that even the best of the Eastern improved tomatoes are still farther improved by California growing conditions if constant selection is practiced to preserve the best types. For instance the "Trophy" is very largely grown as a late tomato for canners' use, and planters insist upon se- curing California grown seed, but careless seed saving has given us Trophies wddely different from the true type and very inferior. CHAPTER XXXIV. TURNIPS. Turnip. — Brassica napus. French, navet ; German, herbst-riibe ; Dutch, raap ; Danish, roe ; Italian, navone ; Spanish and Portuguese, nabo. Kohl-Rabi. — Brassica cauJo-rapa. French, choux-raves ; German, knollkohl ; Flemish, raap- kool ; Italian, cavolo-rapa. Rutabaga. — Idem. French, choux-navets ; German, kohlriibe ; Dutch, kool- raapen onder den grond ; Italian, cavolo navone. These members of the cabbage family are somewhat arbitrarily classed as turnips for convenience and in ac- cordance with local popular usage. Kohl-rabi has swollen stem, clearly above ground ; rutabaga has a swollen root partly above ground, partly below; the turnip proper is another species of hrassica, which has a swollen root and a manner of growth like rutabaga. In California all these vegetables take a much lower rank in popularity and use- fulness than the cabbage group of the same genus dis- cussed in a previous chapter ; judged as root crops they are inferior in use and esteem to the other esculent roots al- ready considered. They have no local standing whatever for stock purposes, for two reasons at least : they do not endure well our summer heat and drought, but become a prey to fungus and unthrift ; they will not rest and start again for larger root-expansion, as do the beet and the carrot. Such being their weakness and perversity, the stock feeder abandons them, which he can readily afford to do in view of the fact that he has many other more ser- viceable crops. He can have any quantity of immense 352 CALIFORNIA VEGETABLES. l)(3C'ts and carrots which are making their re-enlargement from the previous spring sowing, to feed in the winter; he can have for late summer use, corn and squashes, which grow riotously in summer heat which distresses the turnip. He does well enough without the turnij), in view of its be- havior and his own supplies from other sources. The vegetables, then, which we group in this chapter, must be estimated alone upon their table value, and here, too, they are afflicted by an ill-disposition. They are not good keepers in this climate, and, though they can be packed away in sand for use during our warm, rainy win- ter, the people have other supplies of fresher character in the winter, and do not find either turnips or parsnips as desirable as they are in wintry countries. Turnips and rutabagas are then reduced to claim popu- larity upon their excellence as quickly grown for immedi- ate use when mature, and under this restriction they cer- tainly enjoy a fair measure of popularity. Kohl-rabi is very little used and its narrow fame is chiefly confined to citizens of French and German descent. Culture. — The growth of all these plants is simple and can be undertaken anywhere in California, providing their dislike of summer heat and dry air is borne in mind. The culture methods prescribed for the beet and carrot befit the turnip in the direction of preparation of soil, sowing the seed and cultivation. The plants are hardy against frost and can be successfully produced all through our val- ley winters. Sowing for winter use may begin early in the fall on irrigated ground or as soon as the rains fall. Sow- ing for spring and early summer can be done at any time during the winter when the soil is sufficiently dry and warm for germination and growth of the seedling. In valleys of heavy rainfall and frosts, February sowing may be best for spring use, but in warmer, drier parts earlier sowing is desirable. The plant needs adequate moisture and a moderate temperature, and its growth is a matter of conditions not of the calendar. It is plain, then, that tur- VARIETIES OF TURNIPS. 353 nips are well adapted to winter gardening in California, and, if pushed to maturity rapidly, they will be found very tender and delicious. Sowing for succession will give tur- nips fresh from the soil in all their excellence through many months in our warmer valleys. Both the flat turnips and the rutabagas or Swedish tur- nips are grown in the same way, and both reach edible size very quickly under favorable conditions. Culture is like that advised for the radish except that they need wider spacing. Rutabagas are better keei^ers and more service- able for winter storage than flat turnips, though both are mainly used fresh from the ground in this State. Rutabagas are sometimes transplanted from a seed bed, as space becomes available here and there in the garden for them. They are handled just as cabbage plants are. Kohl-rabi is grown in the same way as common cabbage, both in starting plants and planting out. Varieties. — The flat turnips chiefly grown are Early White Dutch and Purple Top Milan — the latter being pre- ferred by market gardeners. The Purple Top Flat Dutch or Strap Leaf and Purple Top White Globe are also in good favor. Rutabagas are so little grown that there is doubt which has the preference of several good kinds listed by our seedsmen ; the Purple Top Yellow or Long Island seem, however, to be most popular. Of kohl-rabi the White Vienna is usually grown. CHAPTER XXXV. VEGETABLE SUNDRIES. It is not intended to make this volume a complete treat- ise upon the esculent plants which may be grown in Cali- fornia, nor to claim that it contains a complete enumera- tion of those which are actually grown at the present time. Such a task would be appalling in view of the wide adapt- ability of the climate and the fact that our population in- cludes natives of every country under the sun who have brought hither the plants which have delighted them in their old homes. Conspicuous among such contributions to our cultivated flora are the acquisitions from China and Japan, which alone would require much time to identify and characterize. Our acquisitions of minor vegetables from Europe are hardly less interesting. It must be left for some future student to properly arrange all these for public information. In the present work it has been rather the intention of the writer to treat the more conspicuous and widely useful vegetables, because in that line the present demand for information lies. An attempt will, however, be made in this chapter to briefly mention a few plants concerning which inquiry may arise in the minds of readers, and to offer suggestions on their culture. Capers. — Capparis spinosa. The production of "capers" on a commercial scale has frequently been mooted in California, and so far as the local adoption of the plant goes, anticipations of success seem to be well placed. The plant thrives with moderate moisture — enough could be conserved by cultivation on any fairly retentive soil. It has been growing thriftily for years on adobe soil in the University garden in Berkeley, CARDOON AND CHERVAL. 355 and has produced prolifically the flower-buds which are used in pickling. The labor of frequently hand-picking the buds must, however, be considered in connection with any projected enterprise. A few plants for the home gar- den can be strongly commended. They can be grown in corners or in borders and are decidedly handsome in leaf and blossom. Plants may be easily grown from seed in a seed-box or can be multiplied by stem cuttings in a sand box over mild bottom heat. Cardoon. — Cynara cardunculus. The cardoon is closely related to the globe artichoke, and resembles it in growth except that it attains larger size. Its edible part is, however, the stem and midrib of the leaf, and not the flower bud as in the artichoke. It is propagated from seed and not from sprouts, and to pro- duce satisfactory quality, the seedling must be pushed to quick growth by ample manure and moisture. The car- doon is hardy in the coast region, and can be grown for autumn or spring use, or for succession at nearly all times. The plant is ready for use in about six months from sow- ing. During the last three weeks the leaves are gathered up, covered and blanched, and both leaves and root make a delicate table vegetable when carefully boiled. Chervil. — Scandix carefolium and ChaerophyUum hulhosum. There are two edible plants known as chervil, the first furnishes fragrant leaves which are used as seasoning and in salad, the second an edible root for boiling. The first is a hardy annual, and can be grown from seed, as lettuce is — sowing whenever moisture is adequate. It does not thrive in high heat but can be helped by shading where necessary. The turnip-rooted chervil resembles a carrot in form, and may be grown as carrots are. The seed soon loses its germinating power and must be fresh. Corn Salads. — Valerianella olitoria and eriocarpa. Corn salads are popular winter growing salad plants, and are of easy culture. The seed is sown w^henever mois- ture is present in the fall, and a succession of foliage can 356 CALIFORNIA VEGETABLES. be had all through the raiuy season. The culture is the same as for lettuce. The plant also resembles lettuce ; we have some varieties of open growth and some Avhich are disposed to form somewhat compact heads of foliage. In this State both the French and Italian improved kinds are hardy in California valley winters. Cress. — Lepidium sativum, and Water Cress. — Nastur- tium officinale. Garden cress is easily grown all the year in the coast region if the ground is kept moist. The seed should be sown at short intervals, as the leaves come on very quickly. In the interior it is chiefly a winter plant, as summer heat checks leaf growth and carries the plant to seed. Water cress has grown freely in California ponds and pools, and was found in such places by our earlier botanists. In Cali- fornia it makes very rank growth, producing stems five and six feet high and proportionate luxuriance of leaf growth. It usually volunteers freely wherever water stands, filling road-side ditches and similar places. All that is needed is to prepare a place suitable for its growth. Dandelion. — -Leoiitodon taraxacum. This plant has been widely introduced on the moister lands throughout the State, and is used for salad and for boiling, as it appears in abundance after the fall rains. The plant is also grown to a limited extent by foreign-born market gardeners, and some of the improved garden va- rieties have been introduced for their use. It can be grown as lettuce is, whenever the soil carries moisture enough. Gherkin. — Cucumis anguria. This plant is different from the small pickling cucum- bers which are often called gherkins. It is a creeping, branching plant, making a dense mat of stems well laden with small, oval fruit covered with spine-like protuber- ances. It endures heat and drought well, and is very pro- lific even in interior situations in California. MUSHROOMS AND MUSTARD. 357 Kitchen Herbs. It is hardly desirable to enumerate a list of culinary herbs. Each housewife has her own information and jire- ference and beyond that her cook-book is an encyclopedia. Suffice it to say that nearly the whole collection of plants grown in northern climates for fragrant leaves or seeds is hardy in the California winter, and most of them do best with earl}' sowing- — as soon as the soil is well moistened by the fall rains. Most failures with them are traceable to sowing too late, which comes from following Eastern prac- tice. Where the winter is quite frosty, fall sowing is less desirable, but with February warmth the seed should be in the ground. Early sowing enables the plants to secure good rooting, and with that, growth can be carried later in the dry season. Late sowing causes many a plant to dwindle in the summer heat even if irrigation is afforded. It must also be remembered that many plants must be dili- gently cultivated during our dry season which thrive with- out it in the humid summer of other countries. Mushrooms. Field growth of mushrooms is abundant during the rainy season in California — especially do the fall rains bring to view such great quantities of them that they can be easily gathered by bushels. The list of edible mush- rooms in California includes many species which afford a fine field of mycological epicures. Recently there has arisen quite a producing interest in the line of cellar cul- ture of mushrooms chiefiy by foreigners, and their methods are essentially the same that are practised elsewhere, de- scriptions of which are readily available. Publications on the subject may be had free on application to the Secre- tary of Agriculture at Washington which will give the inquirer a good outline of arrangement and methods. Mustard. — Sinapis sp. ^Mustard is a grievous weed in California, especially on rich soils with moisture. It is also sometimes very profit- 358 CALIFORNIA VEGETABLES. able as grown for a seed crop. The young plant is sought in the fields as a salad and improved varieties are culti- vated to some extent. Both the white and the large cab- bage-leaved Chinese kind are grown. The culture is most easy and simple, the treatment being the same as that of lettuce. Nasturtium. — Tropaeolum. Nasturtiums are largely grown as ornamental plants, but the desirability of the flowers for the garnishing of salads and the use of the flower buds and green seed for pickling and as a substitute for capers gives the plants place in the vegetable garden. They thrive almost without care or watering in a corner of the garden, though better growth will show their appreciation of better treatment. They volunteer freely in California from self-sown seed and con- tinue growth all through the frost-free season. They can be trained on fence or trellis or allowed free range as pros- trate plants if space permits ; or dwarf varieties may be chosen, as they bloom and fruit freely with less extension. They require little more from the grower than the cover- ing of the seed*in soil moist enough for germination. Okra or Gumbo. — Hibiscus esculentus. This popular vegetable of the south is not largely grown in California but can usually be had from market garden- ers. It requires generous moisture supply to thrive and does not take at all kindly to dry heat. Plants may be started in the winter in the ways described for the tomato, and the planting out and treatment is like that of egg plants ; or seed may be sown for later crop in the open ground in drills, the plants being subsequently thinned to about a foot apart. The plants should be well cultivated and kept well supplied with water. The Long Green and the White Velvet are the varieties chiefly grown. Parsley. — Apium petroselinvm. Parsley can be readily grown in California by the use of a raised bed for fall sowing for winter use and by sowing ROSBLLE. 359 in the early spring for flat culture for summer use. The culture is like that for lettuce except that the plants need wider spacing and extra care has to be taken to protect the seed from drying out, as it is long in germinating and can not be deeply covered. Good firming of the ground after previous deep culture is desirable, and a light mulch will help to retain moisture and facilitate watering with- out crusting the ground. Roselle. — Hibiscus subdariffa. This interesting plant, resembling in its growth okra or gumbo, is a native of tropical Asia and Africa, and has been widely distributed through semi-tropical countries, where it has been found to possess considerable resistance to drought and to yield very acceptable food products. It has recently been introduced in California — the seed hav- ing been distributed by the State University. The plant is very ornamental, the dark red stems and pods showing through the rather scant dark green foliage. The flowers are of a yellowish white with a dark red center, two in- ches across and lasting only an hour or so during fair weather. The juice extracted from the fleshy calyces or husks is used with water to make an acidulous cooling drink, but is of most value in jelly-making. The muci- laginous properties of the juice render the "setting" of the jelly certain, with a reasonable amount of cooking. The dark sherry color of the jelly and the sprightly acid make it nearly if not equal to currant jelly. Irrigated plants produce a more highly colored fruit, but come into bearnig later. Unirrigated plants put their strength into fruit, but the irrigated plants start lateral branches, which ulti- mately produce several pods, while the unirrigated plants have but one pod. As the plant will endure quite heated and arid situations, it promises to be of much value for jelly-making where currants do not thrive. The plant should be given ordinary garden culture, sowing the seed when danger of frost is over. Enough of the pods should be allowed to ripen to yield seed for the following year. 360 CALIFORNIA VEGETABLES. Sea Kale. — Cvamhe luaritinui. This plant is but little grown in California, and then only by professional gardeners. It requires long use of the ground and considerable attention in provision for blanch- ing. Plants may be grown from seed, if it is fresh, as to- mato plants are grown, and planted out at about three feet apart each way. Plants can also be grown from root cut- tings as described for horse-radish, placing them about three feet apart each way. Plants from root cuttings should be allowed free growth for at least one year, and seedlings twice as long. Preparation for use consists in covering the plant with an inverted pot or box as the shoots appear and allowing it to make its growth in the dark, thus producing blanched and tender midribs. In cutting, the knife should go below the root crown, as new shoots come readily from below. Old roots are productive for many years if allowed to grow freely but not to form seed after the early growth is cut for use. Soy Bean. — Soja hispida. This plant has been tried and discarded by a number of growers as unthrifty in our dry summer, but good crops are grown on low, moist lands especially by the Oriental element of our population. Square-pod Pea. — Lotus tetragonolohus. This plant has recently acquired some little popularity in California as a table vegetable. It will make a good win- ter growth in some regions of the State, though a little spring heat is more pk.asing to it. Its culture is like that of garden peas, and, if sown during the rainy season, will bear an abundance of edible pods for early spring use. The pods should be gathered when young and tender and are cooked like string beans. Chinese Yam. — Dioscoria batatas. This climbing plant grows thriftily in California and sends its fleshy roots, which are the edible part, so deep that it seems to contemplate return to its native country. A FOLIAGE BEET. 361 To get the roots one has to dig a well several feet deep, be- cause they are so brittle that they will stand no pulling whatever. With present prices of labor in this country it is not profitable to go into deep mining to get starchy food, and the plant is grown only as a curiosity. Chard. — Beta vulgaris. This plant is a beet grown for its foliage and not for its root which is small and branching. Its cultivation is, how- ever, exactly like that of the beet root, except that its root- ing habit allows of shallower tillage but it enjoys good conditions in the soil and manifests its delight by grander foliage which is very desirable and is used as spinach is. It is not largely grown in California, because conditions are so favorable for continual supplies of spinach, which is preferred.
