Oci.Ar97 08a, & FRIENDS OF YOURS 'VERY DAY we hear someone say "Why do we have so many more insect pests now than we used to have? I can't raise a thing — fruit, flower or vegetable — without a pitched battle with insects." We have been killing insect-eating birds by the thousand for fun and for food and by the million for their feathers. Our forests are being cut down and the few trees that remain in our cities and towns are being hacked and trimmed by the telephone and trolley companies until l^ut a few stumps remain, and but few artificial nesting or retreating places are replacing the natural ones destroyed. While our helpful birds are being driven away and killed we offer protected nesting places in the cornices and eaves of public buildings and an abundant food supply from street droppings to the foreign, not-fit-to-be-naturalized, piratical English sparrow, who destroys the young of the insect-eating birds and lives on seed and grain himself. Thus Man has up- set one of the most important balances established by na- ture to control the 'nsect growth and is paying for his folly by the increased number of insect pests. In our efforts to restore this bal- ance every natural insect enemy should be encouraged and instead of getting after the thousands of worms we should go after the butterfly before she lays her eggs. Part of the millions spent for poison and spraying should be used to exterminate the egg-laying butterfly and moths. Here again the bird helps, as moths are one of their special "tid-bits." Do not spread insects, or allow an opportunity to pass for destroying them. Every one can help a little. The mother who tells her little son to "let the little birdie go and not harm it," when he traps a butterfly under his hat, helps to keep up the high cost of destroying SmiUNC CWeHICAL CO., CAMBRIDOe, MASS.

Make shallow holes in the ground and cover them with flat stones or boards. They will use them daytimes for shelter. Farmers and gardeners wherever possible should propagate toads. They breed in swampy places the same as frogs and little toad, tadpole, requires little or no attention. Toads generally remain near the locality where they are raised providing the food supply is plentiful. All insects are not injurious. One of the best known beneficial insects is the lady bird, sometimes called lady- clock, lady cow. lady fly, lady bug, but known best as "lady beetle." There are some ten species of this well known friendly insect, which is very destruc- tive both as beetles and larvae, to many forms of insect life, especially to aphis. They are hemispherical in form, with a smooth, polished surface, and are often colored red, brown, or black with small spots of brighter colors. About the worst sin committed by toads is that they occasionally (by mistake no doubt?) kill one of these helpful insects, but this trangression is not frequent. These Lady Beetles as well as their young or larvae are often mis- taken for injurious forms and are unfortunately killed. The Lady Beetle young vary in length all the way up to about a half inch, are bluish or blackish in color, often with orange spots on the back, and resemble very much a miniature alli- gator in general appearance. They crawl about freely and do wonderful service in destroying large numbers of plant lice, scale insects, etc. Always encourage and make existence eas5^ for the natural insect enemies, birds, toads, helpful insects and parasites.

Near the rear end of the back there are two large, brilliant orange spots. The hairs on the sides of the body are barbed. These the caterpillar sheds at maturity, and per- sons upon whom they fall suffer from a serious unpleasant itch. When matured they spin a cocoon around themselves and emerge as a moth in about two weeks. The female is about one and one-half inches from tip to tip of wings and is clear white except that she has a large tuft of brown hairs on the extreme rear end of her body. These moths are great night fliers and cover great distances. This makes it impossible to limit their zone of operation.

They crawl to some secluded place and change to the chrysalis stage, from which the parent butter- flies appear about two weeks later. There are several broods each year, the winter being spent in the chrysalis stage. Control: Duiing the first two months of growth, cabbage l)iants (it is claimed by many) can be sprayed with Sterling'- worth Arsenate of lead without danger of poisoning from eating the plants later. Chemical tests seem to have proved this. A whale oil soap solution added to the Aisenate of lead aids in sticking- it to the plants. After the plants are well headed, if further treatment is necessary, use Sterlingrworth Hellebore (page 54) or Sterling-worth He-Bo, see page 54. CABBAGE IiOOFER. The history of this insect is similar to that of the Cabbage Worm.

This in- sect is a fruit feeder, at- tacking apples and pears in particular, and causes more actual loss to growers of fruit than any other fruit insect. The "wormy" apple is well known and needs no description. The winter is spent by the full-grown larvae in small white cocoons beneath loose bark, and in other protected places. About apple blossom time these larvae change to pupae and the parent moths appear about two weeks later. These moths are grayish-brown m color, have a band of bronze beyond the middle of the fore wings, and a wing expanse of about three- quarters ot an inch.

These hatch in the course of several days and the young worms usually feed a little on the tender leaves before they make their way to the young fruit and bore into it through the blossom end. Practically all of the feeding is done about the core. About mid-summer these larvae become full grown, bore out to the surface and seek a place to form their cocoons. There is sometimes a partial second brood in Massachusetts, the moths of which ap- pear late in July or early August. Control: Spray apple and pear foli- age and fruit just after the blossoms fall with SterUng-wortli Arsenate of lead, page 49 or Sterlingrworth Ar-Bo, (page 48). Don't delay this application. It will be worthless if delayed. Force the spray into the blossom ends. At this time the calyx sepals are open and will hold some of the poison ready for the v/orms when they begin to bore into the fruit. The calyx sepals close a couple of weeks after the blossoms fall and it will then be too late to place the poison where it will be effective. Make a sec- ond application ten days after the first for best results, and spray about the first of August for the second brood. Sterlingrworth Ar-Bo (page 48) will not only control the codling moth but certain fungous diseases as well. It is a double spray, combining two operations in one. CURCU]tIO. This insect attacks ap- ple, pear, pluin, peach, cherry and all pome and stone fruits. The adult beetle is one-fourth of an inch long, dark broAvn in color with gray mottles; has six legs, a very chunky body about half as wide as the beetle is long. The head and snout are shaped like the letter V. With this V-shaped bill a hole is punctured in the fruit and the pulp ex- tracted as far as the bill will reach and STERLING CHEMICAL CO., CAMBRIDGE. MASS. THE- CURCULIO FRUir CONTBOIk OF JmEAT AND FBUIT-EATING, INSECTS, BOBEBS, ETC. — Continued an egg deposited in the hole which is then plugged with a sticliy excrement. The eggs hatch in three to six days and the resulting grub commences to burrow into the fruit. This is its sole vocation for two or three weeks, when the worm or larva reaches maturity. He then bores his way out of the fruit, crawls down the tree and buries himself about two inches deep in the ground, where he forms an earth cell, and in four to six weeks emerges as a beetle. The grubs rarely mature in apples but the injury caused by the egg-laying of the parent female heals over, causing. a russet scar, and frequently gives the fruit a gnarled appearance. Such injury results in a large percentage of second grade fruit. The beetle winters in some convenient, sheltered crack or crevice — sometimes in the ground and sometimes in bushes or partly decayed fruit. Fruit entertaining this pest generally falls from the tree before maturity. If it ripens it's a "cull," the kind of fruit that is packed in the center of the barrel. Remedy: During most seasons the codling moth spray just after the blos- soms fall, with Sterling-worth Arsenate of Iiead or Ar-Bo will satisfactorily con- trol curculio also, but where severe in- jury has been caused previous seasons by curculio, and especially if the season is rainy, two sprayings are advisable, the first being applied just after the blossoms have fallen, and the second ten days later. Jarring the trees over sheets in the early morning at the time when the fruit is setting, and destroying the beetles thus collected will materially reduce injury. Shallow cultivation of the orchard during the summer will destroy many of the insects pupating in the ground and is also an excellent practice for preserving the moisture.

They feed entirely at nig-ht upon garden and otlier plants, cutting them off near the ground. During the daytime they lie coiled up just uuaer the surface of the ground. The eggs are laid in July and August, grassland being preferred. Land which has re- cently been in sod and planted to crops is likely to be badly infested. The eggs hatcli in a short time and the young worms feed to some extent in the early fall before seeking winter quarters in the ground. Most of the injury is caused by these caterpillars in the spring. They become full grown the latter part of June or early July, when they crawl into the ground and change to pupae, the moths emerging later. There is a single brood each year. Remedy: Plow or spade up land to be planted another season as late in the fall as possible. This will destroy many of the worms wintering in the ground. If plants show injury, spread poisoned bait such as Sterling'worth Cut Worm. KiUer (page 25) THINLY over infested fields or gardens. Make the application at dusk in the evening. ARMY WORMS AND GRASSHOPPERS — A poisoned mash is the best known control for these insects.

They are heavy eaters and change to a yellow color as they grow. They ma- ture in two or three weeks and are then about one-half to five-eighths of an inch long. At maturity they pass down the tree and pupate in the ground and emerge in about six days as beetles. They en- ter sheds, houses or any other sheltered winter quarters at frost time and are found many times in dwelling houses in the spring. Kill them. Don't let them out. They want to lay their eggs in the trees. Bemedy and Preventive: Spray with Sterlingworth Ar- senate of I^ead (page 49) as soon as the beetles appear, which is about June 17th in latitude of Boston. EUBOPEAN COBN BOBEB. This insect is a European species which has become established in Essex and Middlesex counties in Massachusetts during the past few years. Pres- ent indications are that this will be the worst corn pest we have. Usually the first indication of injury is the drooping of the tassels which are mined out and destroyed by the cater- pillars, often before their function of fertilization has been performed. This ineans a reduction in the "set" and a loss in yield. In addition the caterpillars make feeding tunnels all through the stalks and even injure the ears themselves. The parent moths are of a deep yellow color and have a wing expanse of about an inch and a half. The wings have numer- ous zigzag cross lines of a brownish color across them. There are two broods of these insects each year, the moths of the first brood appearing in May and those of the second brood in August. The larvae of this second brood are the more injurious and cause severe injury to late corn. The larvae of the second brood spend the winter in the stalks, change to pvipae in tlie spring and the moths appear soon after. Control: Since practically all feeding is done within the stalks, treatment with insecticides is useless. In the fall all corn stalks should be disposed of either by burning, feed- ing to livestock, or should be so deeply composted that it will be impossible for the larvae to survive. Carelessness in overlooking a few stalks, or on the part of a few persons in not carrying out these recommendations, may lead to a serious infestation again another season.

Similar to the Round Head Apple Borer described below except that it attacks the tree trunk higher up and many times bores into the small branches. Remedy: The same as for the Round Head Apple Borer. To Prevent: Reduce a quantity of Sterling"worth Whale Oil Soap with To- bacco (page 47) to the consistency of heavy cream by adding washing soda and water. To each gallon of this mix- ture add two ounces of crude carbolic acid. Paint the trunks with this mix- ture. Remedy: Dig them out with a knife when near the surface or kill by running a flexible wire into tunnel. If you can- not reach borer with a wire squirt a little Sterlingrworth Borer Oil (page 50) into the tunnel and plug the hole with putty. The vapor does the rest. FIiEA BEETIiE.

The egg- mass is yellowish. No climatic change appears to have any effect on their fertility. The young caterpillar w^ien hatched in the spring is about three sixty- fourths of an inch long. They feed at night and hide during the daytime. During his life he passes through at least five changes. At each change he in- creases in size. When nine to twelve weeks old he is two inches long. At this stage he is hairy, dark grayisli in color, and has two rows of beautiful colored spots on his back. The first ten nearest the head are bright blue and the balance are blood-colored. It now seeks some sheltered spot, changes to the pupae stage and emerges as the moth a couple of weeks later. The male moths are great day-light fliers. The female is larger than the male and meas- ures two inches or more from tip to tip of wings. She is white in color with dark mottled marks across the wings and does not fly. Control: The Gypsy Moth attacks nearly every known tree and plant. The most effective way of fighting is to de- stroy the egg clusters any time between September and April by painting with Sterlingrworth Gypsy Motli Creosote, (page 51). Banding trees with burlap which offers concealment for the moths and pupae, helps if you look under the burlap daily and destroy all insects gath- ered there. It is of no use to burlap trees unless you do this. If your trees become badly infested through imperfect protective measures, spraying with Ar- senate of Lead is the only recourse (page 49).

The young or caterpillar of the leop- ard moth is a borer in shade trees, ornamentals and other plants. Trees in the vicinity of Boston have suffered severely from this borer and many trees have been killed by it. The parent moth is white, spotted with black and has a wing expanse of over two inches. The moths begin to appear the latter part of May and are seen until September. The eggs are laid in crevices of the bark and the young caterpillars from these bore through the bark to the woody tissue be- neath. It requires two years for the borers to get their growth. They are then about two inches or more in length, white in color and marked with numerous tiny black spots. ^^^hen mature they change to pupae just beneath the outer bark, and the moths emerge a few weeks later. It is sup- posed that the reason why these borers are so injurious about Boston and certain other large cities is the absence of wood- peckers and other insectivorous birds in such places. The leopard moth has never become a pest in less thickly popu- lated places where insectivorous birds are more common. Bemedy: Poison sprays are useless against this insect since it feeds almost entirely within the wood where it cannot be reached by such materials. Infested trees maj^ be detected during the summer months, when the borers force large quantities of woody material through the openings to their tunnels. Badly infested trees should preferably be cut down and the w^d burned before the borers can mature. Valuable trees or ornamental plants should be gone over carefully and a flexible wire or knife used to destroy the borers. When these cannot be easily reached, a small quantity of Sterllngf- worth Borer Oil (page 50) or Carbon bisulphide should be in- jected into the tunnels and the openings closed with putty or grafting v.^ax. Both of the above remedies produce a gas which penetrates the tunnels and kills the borers. Carbon ])isulphide is inflammable. Keep all flre away. PEACH TBEE BOBEB: This borer is the young of a delicate, clear-winged moth, having a blue-black body, an orange band across the abdomen and a wing expanse of about an inch. The parent moths a'ppear from June to September and lay their eggs on the trunk of peach trees near the ground. These young bore their way through the bark but usually remain close to the surface until the following spring, when they bore in deeper, become full grown in early sum- mer, change to pupae and the moths emerge soon after. There is a single brood each year. The injury by these bor- ers causes gum to exude from the tree close to the ground and gives the tree a filthy appearance. Page sixteen sterling chemical co., cambridgb, mass. GONTTItOIi OP IiXSAF AND PRUIT-EATlMfa, INSECTS BORERS, ETC. — Continued Remedy: Mound up the earth for a foot or so about the peach trees. This will force the moths to lay their eggs hig-h^T up where the young- borer can be more readily found and destroyed. Do this not later than the first of July The trees should be gone over in October, the earth removed and the young borers destroyed with a knife, or paint the trunk above the mounded earth with Sterling-worth Borer OIL (page 50). ^ POTATO BUG OR COI.ORADO BEETI.E. This insect confines his attention exclusively to the potato. He is so familiar we will not describe him. The hard-shelled, striped beetles lay eggs in yellow clusters on the under side of the leaf. They hatch in SIX to eight days into a soft, reddish slug which does the damage. At ma- turity the slugs descend to the ground, pupate and form the striped beetle which again lays eggs. Two to four broods hatch each season. Preventive: If you have but a few hills, watch for the striped beetles, l^ick them and destroy the eggs. Por a Remedy, spray with Sterling-worth Ar- Bo (page 48). This is a combined poi- son and fungous remedy. By using it you kill with one spraying the bugs and prevent many fungous diseases. Potato vines sprayed with this mixture stay Potato Bug and Slug green a long time, resulting in a larger tuber. It does not cost anything to spray with this mixture, for the increase in yield pays for time and material. ROSE BUG OR ROSE CHAPER. About the first of July the female beetle burrows into the ground and lays ten to twenty eggs. AVorms or larvae hatch in about eight days. They are small and feed on any nearby vegetation until fall. They hi- bernate in the ground during the win- ter and dig out in spring, enter the pupa state, and emerge as beetles in two or three weeks. The beetles which do the eating are brown colored, have long spindling legs and are great fliers. They generally appear suddenly in large num- Rose Chafer STERLING CHEMICAL CO., CAMBRIDGE, MASS.

To Protect Grape Clusters: Tie a paper bag about them soon after forming. Remedy; When possible hand picking and destroying the beetles will be found most satisfactory, since they are very resistant of poison. Infested plants may be sprayed with a strong solution of Sterlingrworth Ar-Bo (page 48) which has been sweetened with molasses. Sterling-worth He-Bo (page 54), or good, fresh Sterling'worth Hellebore (page 54) has been found effective for roses. BOUND HEADED AFFILE TBEE BOBEB. This insect is hatched from eggs laid by the beetle in the bark crevices near the ground. The resulting larvae gradually bores into the tree. His presence may be identified by the sawdust-like chips which fall from his workshop. At maturity it is nearly one inch in length. This insect attacks apple, quince and accasionally pear. To Frevent: Reduce a quantity of Sterling'worth Whale Oil Soap -with Tobacco (See page 47) to the consistency of heavy cream by adding washing soda and water. To each gallon of this mixture add two ounces of crude carbolic acid. Paint the trunks with this mixtrue. Bemedy: Dig them out with a knife when near the sur- face or kill by running a flexible wire into tunnel. If you cannot reach borer with a wire squirt a little Sterlingfworth Borer Oil (See page 50) into the tunnel and plug the hole with putty. The vapor does the rest. SHOT HOI^E BOBEBS. There are several species of tiny bark beetles which attack trees in an unhealthy or dying con- dition. To Frevent: Cut down and burn the infested trees. Bring the others into a healthy state by fertilizing and cul- tivation. Paint tree trunks and well up into the branches with whitewash to which a little Portland cement and eight ounces of white arsenic to each gallon of mixture have been added. SQUASH VINE BOBEB. This insect is one of the most destructive of the many enemies of squashes. The damage is due to the larvae boring througli the stems, causing them to rot or so injure the vine as to cause the plant to wilt and die. These larvae are the young stage of a brov/nish, clear-winged moth, having a wing expanse of about an inch. The moths appear about the second week in July and lay their eggs along the stems. The borers which hatch from these eggs feed within the stems and become full grown in about a month. They then desert the stems and burrow into the earth an inch or two, where they form their cocoons, change to pupae and thus pass the winter. There is a single brood each year. Page eighteen sterling chemical co., Cambridge, mass. A CONTBOIk OF IiEAF AND FBUIT EATING INSECTS, BOBEBS, ETC. — Continued Remedy: The presence of \,he borers feeding within the stems often becomes evident by the presence of coarse yellow- ish excrement which is forced from the burrows and accumu- lates on the ground beneath. The sudden wilting or dying of the leaves during mid or late summer is also usually an indication of borer injury. When possible, cut out and de- stroy the borers and cover the injured portion of the stem with earth to encourage secondary roots. These secondary roots will carry the plants through and enable them to mature their crop. Destroy old plants and dead vines as soon as the crop is gathered. Early varieties of squashes will act as a protection to late squashes. Plow fields to be planted as late in the fall as possible and harrow these again in the spring. This will destroy many of the insects winter- ing in the ground. Keep the plants vigorous by cultivation and the use of fertilizers. If possible do not plant near land infested the previous season. TENT CATEBFII.I^AB. In the spring about the time the foliage begins to expand from the buds, small whitish webs are often found in the crotches of wild cherry and apple trees. These tents are made by the apple-tree tent caterpillar, which, when full grown is about two inches long, black with a light stripe down the back and with dots of blue and white along the sides, and clothed with yellow- ish hairs. As the caterpillars increase in size the tent is made larger. The tent is the home of the caterpillars on cool or stormy days or nights. The winter is passed in the egg stage, the eggs being laid in a small mass about half an inch long and glued to the twigs with a sticky substance which hardens later. The parent moths are light brown in color, have two white bands across the fore wings and a wing ex- panse of about an inch. These moths appear usually during the latter part of June. There is a single brood each year. Control: ^Vhen possible, destroy the winter egg-mass by removing and burning. Destroy wild cherry trees which are useless and serve as a breed- ing place for these insects. While the tents are still small in the spring destroy these together with the young caterpillars Nest of Tent Caterpillar STERLING CHEMICAL CO., CAMBRIDfiE, MASS.

Do this on a cool, dark day or at dusk on a cool eve- ning when the caterpillars are all at liome. Do not burn the tents off. This will injure the trees. The treatment for codling moth with Sterlingrworth, Ar-Bo (page 48) will destroy the caterpillars without further attention if the infesta- tion is a mild one. TOMATO WORM OR TOBACCO WORM. The eggs from which this caterpillar is hatched are laid by the motli the last of June. They hatch in six days, the resulting worm, which i-eaclies maturity in about three weeks, grows to be three inches long, and in diameter to the size of the little finger. Projecting from the end of the body is i horn a quarter of an incli or more in lengtli. These worms burrow into the soil at maturity, pupate and emerge in the spring as moths. Tomatoes and to- bacco are the plants generally attacked. Remedy: The worms are so large and generally so few that hand picking is easy. Spraying with Sterling-wortli Ar- senate of Iiead (page 49). five pounds to fiftv gallons of water, will be effective. ' TUSSOCK MOTH. Eggs are laid in early fall by the gray-colored wing- less female moth. They are shiny white in color and are deposited in clus- ters of two to three hundred on the bark of the tree. They hatch in the spring and the young caterpillars com- mence eating leaves at once. They ma- ture in a month's time, spin a. cocoon about themselves and emerge in a short time as moths. The matured caterpillar is bril- liantly colored; head is bright red, body j TU.550CJS. gray and covered with long red, yellow (^TEHPIiLAl and black hairs and feelers. The under t=r .- _'-.j r-??^^'!L— side of the body and legs are yellow. Remedy and prevent- ive are the same as for Gypsy Moth (page 14).

'UCKING insects have a beak M-ith which they pierce beneath the surface of the host and extract the juices from within. Where sucking insects are feeding, the tissues a!e not actually eaten but the extraction of the juices causes a withering, curling or dying of the affected portion, and an examination will usually disclose the pres- ence of insects of this type. A CONTACT INSECTICIDE is necessary to control such insects and since each insect must be hit by the spray in order to be killed, thoroughness of application is very essential. First determine what sort of an insect you are dealing with, tliat is. whether it is a chew- ing insect or a sucking insect, and then apply the proper remedy at the right time. APHIS OR PLANT LICE. There are hundreds of species of this insect. They attack both root and leaf of nearly all plants, shrubs, trees and vegetables, and get their sustenance by sucking the sap. Fifteen or twenty species do most of tlie damage in this climate. They are all minute. Some have wings and some are wingless. Those attacking the roots of plants and trees are as a rule blackish or bluish in color, while those infesting leaves and stems of plants and vege- tables are generally greenish in color. There are exceptions but generally speaking the above color description holds. The color appearance is often changed by a covering of dust. Those species which infest leaves will generally be found on the under side and in the process of feeding they roll or curl the leaves. One of the recent additions to this family is the Green Pea I^ouse. His body is about three-sixteenths of an inch long, spread of wings the same. His color is the same as the pea leaf which he makes his host. The process of development of plant lice or Aphis is re- markable. The female lays her eggs in the fall, from which a colony of females hatch in the spring. These females give birth to live young without intervention of the male, which multiply so rapidly that the progeny of one female left un- disturbed would reach several million in a season. Preventive: Examine the roots of all shrubs or trees before setting. If you have a suspicion of lice oj' eggs in dirt clinging to the roots, mix the soil that is to be next to the roots with fine powdered tobacco (page 53) and moisten with water so as to make a "mush" before setting tree into it. Ants are fond of Aphis because these tiny insects furnish them with a sweet substance called honey dew, and in return protect and spread them from plant to plant in caring foi- them. To keep the ants down, band your trees and shrubs STERLING CHEMICAL CO , CAMBRIDGE, MASS.

Sterlingfwortli Kerosene Emulsion (page 4 9), Sterlingworth Whale Oil Soap with Tobacco (page 47), Ster- ling-worth Scale Killer (page 50), Ster- ling-worth Plant Lice Killer (page 56), are all reliable sprays for those species which attacl<; vegetables, shrubs and trees above ground, but we particularly rec- ommend the last named for house plants. For those lice which attack the roots use Sterlingworth Mag-g-ott Acid (page 51), and Sterlin^worth Fowdered Tobacco (page 53). Always spray the under side of the leaves. If leaves are rolled or curled dip them in the spray. Your spray or dusting powder must come in contact with the body to kill. For those lice which make the roots of the tree their host, like woolly aphis, soak the ground around plant with Sterlingworth Kerosene Emulsion (page 49) or Sterling-worth Mag-g-ot Acid (page 51). InEAF HOPPERS. These insects are about one-eighth of an inch long, have blunt heads and are striped with yellow and red. They are quick long jumpers. They work on the under side of the leaves and by sucking the sap cause them to dry up and die. They hibernate in rubbish heaps, grass or any sheltered place dur- ing the winter; emerge in early spring and lay eggs just beneath the surface in clusters of eight to ten. From these the young white hoppers hatch in about two weeks. They attack all kinds of plants, but principally the grape, and are hard to combat. An ounce of prevention saves weeks of spraying, so watch the under side of leaves and if the small, white young appear, spray quickly with Sterling-worth Kerosene Emulsion (page Page twenty-two Leaf Hopper STERLINO CHEMICAL CO., CAMBRIDGE, MASS. CONTBOi; OF SUCKING IITSECTS— Continued (FJmAISIT IiICE OB AFHIDS, SCAIiE INSECTS, ETC.) 49) or Sterling-worth Whale Oil Soap with Tobacco (page 47). ONION THBIPS. This insect is almost microscopic in size, and causes by its sucking- injury to the onion known as silver top. white blight, etc. Entire fields of onions are often ruined by this species which also attacks various other gar- den plants. Control: As soon as injury becomes evident, spray the plants with any one of the following remedies: — Sterling-- worth Whale Oil Soap with Tohacco (page 47), Sterlingworth Kerosene Emixlsion (page 49), or Sterling-worth Plant Lice Killer (page 56). Spray thoroughly, covering the plants as well as the ground just around them. It might be found de- sirable to repeat the operation in about a week's time. OYSTEW SHELL SCALE. These insects remain in the ef^g state under the female scale until about the first of June. They then appear as minute white crawlers. They settle and commence to penetrate the outer bark and suck the tree juices. The adult scale can easily be deter- mined bj^ the shape of its back, which re- sembles an oyster shell. Poplars, Wil- low, Lilac, White Ash, and Apple are the plants most often infested seriously. To destroy — spray with Kerosene Emulsion (page 49) or a solution of Sterlingworth Whale Oil Soap with Tobacco (page 47) as soon as you see the young crawlers. If you spray regularly for San Jose Scale that spraying will take care of the Oyster Scale also. RED BUGS OP THE APPLE. These insects have became quite prevalent in Oyster Shell Scale Massachusetts the past few years and on twig their injury to the fruit and foliage of the apple is now not an infrequent occurrence. The injury to the fruit is characterized by a stunting or puckering of the surface, accompanied by pits or depressions, due to the punctures made by the insects in feeding. The injury to the leaves is comparatively unimportant. The life cycle of the two common species of red bugs is very similar. The eggs hatch soon after the opening of the leaves of the fruit buds and the minute red nymphs at once begin to feed upon the tender leaves, usually causing clusters of small red dots by their punctures. As soon as the fruit sets, it is at- STERLING CHEMICAL CO.. CAMBRIDGC, MASb. Pnpe twenty-three CONTROI.

Remedy: If injury by these insects is suspected or has occurred during previous years, spray the apple trees thor- oughly just before the blossoms open with Sterlingrworth Whale Oil Soap with Tobacco (page 47) or with Sterlingworth Kerosene Emulsion (page 49). A second application may usually be made to ad- vantage just after the blossoms 'fall, combining either of these materials with your codling motli spray. Red bugs are very wary and even in badly infested orchards are so agile in hiding that it is difficult to locate them. "BED SFIDEB." This is not a true insect but belongs to the spider group, being almost invisible to the naked eye. It has long been one of the most serious pests with which growers of greenhouse cucumbers and other plants have had to contend. It is estimated that green- house men in Eastein Massachusetts lose a total of no less than $100,000 each year due to the destructiveness of this pest. Various fruit, ornamental plants, shade trees, etc., growing out of doors are also subject to injury, which con- sists of the extraction of the juices from the foliage, causing the leaves or stems gradually to dry up and die. All feeding is confined to the under side of leaves. Control: Recent experiments conducted at the Massa- chusetts Agricultural Experiment Station have demonstrated conclusively that "Red Spider" can be controlled and injury to greenhouse cucumbers and other plants prevented by a thorough application of Linseed Oil Emulsion. Sterling'worth Bed Spider Emulsion (page 53) is prepared according to the approved formula and with our facilities for manufacture, it will be found cheaper and more efficient than the home made emulsion. On plants growing out of doors which are less susceptible to spray injury, Sterling'worth Kerosene Emulsion (page 49) or Sterling'worth "Whale Oil Soap with Tohacco (page 47) or Sterling'worth Plant Lice Killer (page 56) will be found effective. Spray the under side of the leaves and spray tlioroughly. Begin spraying as soon as injury is evident. Don't delay. Page twenty-four STFRLING CHEMICAL CO , CAMBRIDGE, MASS. I CONTBOI. OF SUCKING INSECTS — Continued (FI.ANT I.ICE OB APHIDS, SCAI.E INSECTS, ETC.) SAN JOSE SCAIiE (pronounced San Hosay) is the worst l)est of the twentieth century. Recent investigations by Dr. Marlatt, of Washington, seem to prove quite conclusively that the original liome of the San Jose Scale is in Cliina. The full-grown scale is about, the size of a pin-head round in sliape and grayish- brown in color. It attacks bark, leaves and fruit. The part seen is not the Insect but the shell or scale which cov- ers it. If tlie scale be lifted by Ivnifu or pinpoint, an orange- yellow specie may be seen, which is the insect. Each female produces in June or July, three hundred to five liundred young, whicli are born alive. Tlie young rest on the barl<; and feed on the sap through the beak. They mature and produce young in about a month. It is esti- mated that a single female produces upwards of three bil- lion insects in a single year. The light-colored scales about the diameter of a com- mon pin which have just set- tled down, as well as somewhat larger and darker scales about the size of a small pin-head, may i^erhaps also be observed against the smooth bark on young wood. When the bark becomes quite thoroughly cov- ered with the scales it assumes a rather rough, scurfy ap- pearance of an ashy-gray color. When rubbed with the hand, or better, with the thumb-nail, a yellowish liquid appears, due to the crushing of hundreds of insects. This liquid gives a greasy feeling to tlie bark wliere it has been rubbed. On very young wood, especially if of a bright greenish color, the scale will be surrounded by a reddish discoloration. This is true mIso on fruit, and of course it shows best on green fruit and on light-colored varieties. Care must be used, however, not to confuse the red spots formed by fungous diseases, such as Entomosporium maculatum, with those of the scale. If the outer bai'k, even thougli dark and showing no dis- STEPMNG CHEMICAL CO., CAMBRIDGE, MASS.

Remedy: Agricultural Experiment Stations recommend Lime and Sulphur Wash Sprays and Miscible Oil Sprays, as the most satisfactory. These should be ap- plied in the fall or winter when the tree is dormant, or in the early spring, and in case of badly infested trees in both fall and spring. For a quick, effec- tive remedy when you can spray but once and must give the tree prompt re- lief we recommend Sterlingfworth Scale Killer (page 50). Where you can spray regularly use Sterling'worth Ijime and Sulphur Wasli (page 46). If you discover your trees are in- fested after the leaves have sprung, paint the trunks and large limbs with Sterling-worth Whale Oil Soap with To- bacco (page 47) and spray the leaves with a light application of either Sterling'worth Scale Killer (page 50) or Sterling'- worth Kerosene Emulsion (page 49). This will hold the scale in check until you can treat when tree is dormant with Sterling'worth Scale Killer or Sterling-worth Iiime and Sulphxir "Wash. This pest attacks all fruit trees, many shrubs and vines and some shade trees. SPRUCE GAImIm IiOUSE. Injury by this pest results in the formation of somewhat cone-like, many-celled galls of about three-quarters of an inch in length, usually accom- panied when the infestation is bad, by a more or less severe dropping of foliage. Norway and white spruce are attacked i Underside of female scale insect, showing proboscis or sucking tube. Greatly enlarged — After Howard, U. S. Dept of Agr., Bur. of Ento.

There are two broods of these gall lice each vear hut only one of these makes galls. The e|gs of thi first genera- tion are laid about the middle of May iS'clusters on ?he^spru?e bark These eggs hatch in about a week and the young crawl about and hnally settle down at fresh galls just started by the parent gall lice. As the galls develop they gradually close over these insects, leaving them in small chambers surrounded by the outer par- tition of the gall. Early in August the insects become full grown and about this time the galls, which have previ- ou.sly been green, turn yellow, dry and split open, permitting the full grown lice to escape. The latter part of Aug- ust the eggs of the second brood are laid. These hatch late in the fall and the young pass the winter in protected crevices of the bark, continuing their development the next spring. Control: Success in the control of this insect means spraying with the l)roper material, at the proper time and spraying tlior- oughly. Sterling-worth Wliale Oil Soap with Tobacco (page 47) or Sterlingworth Kerosene Emulsion (page 49) will control this insect. The proper time to spray is during the month of April, the earlier the better. Don't delay. After the galls start to form, spi-aying is useless. Cut- ting off and burning the galls in June will help control this species but this is hardly practicable except in the case of a fevv' small plants. SQUASH BUG. The mature squash bug is of a gray-black color and slightlv over a half inch long. The younger bugs are of a gray color and usually feed in groups on the under side of the leaves. The eggs are brown and are laid in clusters on the under side of the leaves. Injury consists in the extraction of the juices of both leaves MERLiNG CHEMICAL CO., CAMBRIDGE, MASS. Fagc twentysBven Gail loui^e. Squash Bug CONTBOI. OP SUCKING INSECTS— Continued (PLANT LICE OK APHIDS, SCALE INSECTS, ETC.) and stems by all stages of the insect from the young- to the adults. Serious infestation often results in the death of the plants in a short time. Remedy: Place pieces of boards, shingles, etc. among the plants. The adults will seek shelter under these at night, where they may be found after dark or in the early morning, and destroyed. Destroy the eggs whenever these are found. The best way is to cut out the small section of the leaf bearing them and burn it. These remedies are, of course, liracticable only over small areas. Spray the young bugs with Sterling-worth Whale Oil Soap with Tobacco (page 47) or Sterling-worth Kerosene Emulsion (page 49). Each bug must be hit by the spray. While the plants are still young, keep them well cultivated and use a fertilizer to make them grow vigorously. Dust the plants thoroughly while young with air-slaked lime. This will repel the bugs and they will search for plants elsewhere upon which to lay their eggs. As soon as the crop is gathered, rake up the plants, allow them to stand for a day so that the bugs can collect on them again, and then destroy bugs by spraying with kerosene oil. CONTROL OF SUBTERRANEAN INSECTS ^^^^.^HESE insects work in the soil and are perhaps the most £ C\ difficult of all to control, since they are not easily »^ ) reached and direct methods of control are not always ^^^ practicable. Subterranean insects feed both by biting off, chewing and swallowing solid food, and by piercing and sucking, according to the species. GRAPE ROOT WORM. The mother beetle appears at blossom time, feeds a little and lays from one hundred to five liundred eggs on the bark. They hatch in two weeks. The young larvae, which are about one-sixteenth of an inch long, drop to the ground and commence to grope around in search of food. Upon locating the vine trunk they work themselves down to the roots and feed. The larvae hibernate deep in the ground. In the spring they come near the surface, form an earthy cell and change into a beetle. Remedy: Sprav with Sterling-worth Arsenate of Lead (page 49). Immediately when the beetles appear — before Page twenty-eight sterung chemical go,, Cambridge, mass. f CONTBOZi OP SUBTERRANEAN INSECTS — Continued they lay eggs — agitate the ground by cultivation when larvae are near top of ground. LETTUCE EABTH-IiOUSE. A cream-colored louse with short legs, extracts the sap from the roots of the lettuce be- low ground. For a remedy use Sterling-worth Magrg-ot Acid (Pcige 51) around stems. BOOT MAGGOTS. There is a large number of these jtests but they all have the same contemptible destructive disposition. These maggots "railroad" your radishes and turnips, and make the roots of your cabbages and cauliflower look mostly like holes. This is one of the meanest garden pests. You never see him or his work until the damage is done. Pre- ventive measures are best. Al- ways sprinkle a ring of Sterling"- worth Powdered Tobacco (page 53) around your Squash, Cu- cumbers, Melons, Carrots, Rad- ishes and Turnips as soon as they are up. When transplant- ing cabbages do the same, or better still place a Sterling-- worth Tarred Pelt Disks (page 51) about each plant. This helps keep off the fly that lays the egg. Make a practice of digging around the roots of those vines favored by this insect every few days and if you have suspicion that he is at work apply Sterling^worth Mag-grot Acid (page 51) at once. If you find your vines wilt- ing don't lay it to drought or something else, look for root maggots and if you find them, treat all your vines with Maggot Acid or be prepared to lose your crop. WHITE GRUBS. These are without doubt the most de- structive pests with which the strawberry grower has to con- tend and various other crops, such as corn, potatoes, grains, grasses, etc., are frequently injured. These large, thick bodied, curved, whitish grubs are the young of the May Beetle or "June Bug," and require two years for their growth and change to the adult beetle. Treatment: The parent beetles prefer to lay their eggs in sod land or in land poorly cultivated and weedy. Crops such as strawberries, corn, potatoes, etc., should not follow Cabbage Root Maggot Fly and Larva S1EPLING CHEMICAL CO., CAMBRIDGE/ MASS. Page twenty-nine CONTBOl^ OF SXJBTEBBANEAN INSECTS — Continued i within two years land that has been in sod, since, owing to the lack of food, the grubs concentrate upon the roots and soon kill them. Clover, beans, peas, etc., are not injured to any great extent by white grubs and may be grown to advan- tage as a two year intervening crop between sod and straw- berries, corn, potatoes, etc. Nothing can be done to prevent injury to plants after it has been started. WIRE WORMS. These are the young of a "click" or "snapping beetle." They are usually yellowish-brown in color, about three-fourths of an inch to an inch long, slender and quite hard, and are especially injurious to corn and potatoes. Remedy: T^ittle can be suggested in the way of a remedy for these pests. The mid-summer cultivation of fields already planted will destroy many of the insects in their pupa cases at this tim.e. and the plowing in mid-summer of fields in sod which are to be planted another season will greatly reduce in- jury by these pests. Various insecti- cides which have been experimented with up to the present time have proved useless from a prac- tical standpoint. Wire Worm Beetle and Larva MISCELLANEOUS INSECT PESTS OUB CREATOR after making Man, seemed to feel that he was likely to be a "lazy cuss," and to keep him in motion and in a healthy, active state, turned seven million insect pests loose in his cave with the injunc- tion to sting, suck, eat. drink and be merry, and ever since then Man has been swatting flies, chasing fleas, killing lice and hunting bed bugs. Man has certainly had to "sit up and take notice," do a little scratching and then keep on taking notice and doing a lot more scratching to keep ahead of these enemies.

THE MOSQUITO. This is a real "honest to goodness" dangerous pest. Never allow one to bite you If you can help it. Kill him as quick as he lights. Don't wait to see how he works "his auger." Kill him. Just think of a mosquito satisfying part of his appetite on a big fat black water snake and finishing out on you. Never visit or live in a place where there are mosquitoes, if you can avoid it. You cannot tell a malarial mosquito from any other, except by close examina- tion and disease is about sure to result if one of them punc- tures your skin. You would not intentionally let a mad dog or rattlesnake bite you. Take the same precaution ag-ainst mosquitoes. Cover all stagnant water with oil. Permit none to stand on your premises or on your neighbors' if you can help it. Mosquitoes always breed in stagnant water. This applies to water in eave troughs, cisterns, barrels, sink drains, cess pools, ditches, swamps, etc. Keep your houses screened and protect the toads and insect-eating birds. THE PLY. The fly is more dan- gerous than the mosquito, a lot more filthy and is with us a longer period of the year. He breeds in filthy places, and then walks over your food and wipes his feet on your skin. He can carry more disease and plant it more quickly than any other insect created. Typhoid fever, tuberculosis, cholera, dysentery, small pox, leprosy, are a few of the diseases he dispenses. Swat him. Catch, him in traps, destroy his breed- ing places. Don't buy milk from any one who does not take precautions to keep flies out of the barn at milking time. Screen your homes, cover the garbage can, destroy the fly maggots breeding in the out-of-door water clos- ets by a treatment every two weeks during the late spring, summer and early fall, with borax water at the rate of three-fourths of a pound of borax to ten gallons of water.

Spray horses and cattle with Guaranteed Cattle Oil (page 55). ROACHES AND WATER BUGS. These insects live in tlie most filthy places imaginable. Sink drains, cess pools and garbage cans are favorite "resi- dential .'sections." They are nocturnal in their habits and do their crawling at night. After thoroughly inspecting the sink spout and garbage can, they start out loaded with filth in search of food. Your food is theirs, so they head for your pantry. They creep over your pastry, crawl tlirough your packages of cereal and burrow in the contents of your flour barrel, leaving a trail of sink filth and disease behind them. They have just one redeeming feature — they eat bed bugs. You seldom find a large number of bed bugs where there are many roaches. Perhaps that sickness that laid you up last year or came near being fatal to "the little one" was caused by one of these pests. It is no disgrace to have roaches, for they may be brought in from many different sources over which you have no control. The disgrace is in keeping them. It is not hard or expensive to exterminate them and Sterlingrworth Boacli Killer (page 69) will do the work. As a pre- ventive keep all food tightly covered — keep the sink clean and cut off every source of food supply. They will leave your premises if you don't furnish them food. BED BUGS. These are so familiar in song and story that they do not need any description. If you can't see them you can generally detect their odor. They may be brought in on your clothes, in the laundry, the grocery baskets or on the dog. It is no disgrace to have them. The disgrace is The Roach Page thirty-two STERLING CHEMICAL CO., CAMBRIDGE, MASS. MISCEI.Z.ANi:OUS INSECT PESTS— Continued in keeping them. Their habits of concealment, infrequency of feeding, nature of their food which consists of human blood and members of their own tribe, make them hard to combat. The Sterlinafworth Bed Bugf Preparation (page 68) and persistence will be found as effective if it can be used. Closing infested rooms tightly, burning sulphur candles (page 52) and thus subjecting the rooms to a fumigation for a peri- od of at least 48 hours will aid materiallv. THE BUFFAIiO BUG. This is another bug that has re- cently crawled into the limelight. He came from Europe, and made himself at home at once. He is harmless with the exception that his specialty is eating carpets, at which trade he works industriously. He is a broad, oval-shaped beetle, almost a quarter of an inch long, with a red stripe down the middle of his back. Eternal vigilance is the best remedy. If you use rugs on the floor occasional cleaning is a protec- tion, but in the case of carpets whicli are not often taken up, close watching is necessary. It is claimed by some that strong, fine powdered tobacco sprinkled around the floor before the carpet is tacked is a preventive. THE ANT. They are the classiest "bug"' in the insect kingdom. They rank in almost the same order of intelligence as Man. They are wonderfully active, and the stunts they do would make suit- able material for a moving picture show. Tlie only sure way to keep them off your premises is to dig a canal around your property and fill the canal with water. There are about fifteen thousand species, of which five thousand have been classi- fied, but the housewife knows just two — "the big black fellow" that tunnelled the custard pie the day that the minister came to tea, and the little red fellow who pulled the cork out of the molasses jug and crawled in.

THE FI.EA. When David Harum said, "A reasonable amount of fleas is good for a dog — they keep him from broodin' on being a dog," he didn't know what he was talking about. Either David never had fleas or they didn't like the taste of his skin and did not bite him.

They never play fair, they jump so quick you can't get a good square lick at them. We haven't a thing to suggest for them on hu- man beings. For dogs and cats Sterlinsrworth Flea Killer (page 69) is satisfactory. BATS AND MICE. The "rat problem" Is one of the most serious that ever confronted man. A single pair will increase, if left unmolested, to twenty millions in three years. His bill of fare includes almost everything eaten by man and a number of articles not included in the human dietaries; for instance, mice, living horses' hoofs, kid gloves, shoes and paper. It is estimated that a single rat will eat 60 cents' worth of g-rain in a year if fed on that alone. The damage they do is not measured wholly by what they eat. Through pollution of food products, they do as much damage as by eating. Their energetic habits of digging under buildings, through embankments, g-nawing wood, cutting holes in sacks, tearing up papers to make nests, add to their list of depredations. The killing of young chickens and fowls, and the stealing of eggs have brought them into disrepute among poultrymen. They distribute disease and their well known fondness for matches has resulted in many disastrous conflagrations. They must be exterminated wherever found. There are in- numerable receipts for driving them; singeing their hair off, tieing a bell around their necks, or painting them red and white and turning them loose among their friends, are all supposed to be sure drivers, but we have always noticed that the fellow who had the most "dead-sure" receipts had the Fage thirty-four stfrlimo chemical co., cambridoe, mass. i MISCEI.ZiAiri:OX7S INSECT PESTS— Continued most rats. We believe that cats, traps and Rat Killers offer the surest solution. For a poison that generally acts with- out unpleasant results, one not likely to injure human beings or pets, try Sterling-wortli Rat Killer (page 67). There are a score of other pests that at times make the housekeeper wish she was not. Among them are cheese mites, clothes moth, ham beetle, yellow-jackets, fish moth, meal worm, punkies, but they are rather infrequent and do not often carry contagion, or do much damage. FOUXiTBY IiOUSE. There are a number of species of this particular enemy of the poultry- men. Some poultrymen who have fought them claim there are at least a million different and distinct species. What lice do to offset the efforts of the Women's Anti Egg Trust Clubs to keep down the high cost of eggs is a shame. They are the per- sonification of persistency boiled down. They feed upon scales of the skin, hairs, feathers, etc., and cause the poultry to become sickly because of their irritation. Success with poultry and lice never occupy the same poul- try house at the same time. If your fowls are lousy either kill the lice, kill the fowls or quit the poultry business. Preventives and Remedy: Pow- ders are most effective against this pest, for the lice remain on the fowl's body and are not easily reached by fluids There is a different Lice Pow- der for every ten square miles in the United States. No doubt an occasional infirm louse about ready to "pass out" is helped "on his way" by some of the stronger powders, but it is a waste to spend money on a large proportion of the Lice Powders offered for sale. Don't buy a powder that does not kill the lice so you can brush them out of the fowl's feathers or so you can see them fall dead from the fowl. Don't think because it is called Lice Powder it will kill lice. Let your eye prove its efficiency (page 63). CHICKEN MITES. These mites are just as fatal to suc- cess with poultry as poultry lice. They are nocturnal in their habits. They seclude themselves in the cracks and crevices of the poultry house daytimes and at night attack the fowls while they are roosting. They subsist upon blood and no fowl Poultry Louse STERLING CHEMICAL CO., CAMBRH>GE, MASS.

No poultryman can afford to feed mites with blood generated from feed at the present high prices. Remedy: Get after them in the cracks and crevices where they live day- times with a good strong liquid lice and mite killer. The stronger the better. Use a fluid that has evaporating qualities and throws off a vapor. The vapor from such killers penetrate where the fluid would not, and helps kill. Do not at- tempt to fight them with watery mix- Chicken Mite tures, kerosene, etc. They are worthy of your most energetic and constant attention (page 62). A little crude carbolic acid mixed with the whitewash used when spraying your hen house helps as a preventive. FUNGOUS DISEASES ELJNGOUS diseases are unlike insects that you can see and crush between two bricks. They are caused by microscopic, parasitic plants which live within the tissues of higher plants and obtain their sustenance from them. These parasites produce a diseased condition on the plant that harbors them. Plants that entertain fungous parasites are called host plants. There are few vegetables, plants or trees that are not host plants for at least one species of fungi. The injury from fungi is as serious as from the eating pests but the cause is invisible and only the result can be seen. The materials mostly used in fighting it are Lime, Sulphur, Copper. Ammonia or Iron. Treating plants that have been attacked helps some, but far better results are obtained by anticipating the trouble and getting in preventive work first. Generally speaking fungous preparations should be considered as preventives rather than remedies. Crops like potatoes should not be planted unless you plan to spray them. No good first quality fruit should be expected unless you spray* for the various fungous diseases to which they are subject. Spraying for fungi costs nothing as the additional increase in crop and better fruit and vegetables more than pays the bill. The following are some of those prevailing fungous dis- eases at this time affecting the most important crops. Page thirty-six sTtRtiNo chemical go., Cambridge, mass. PUNGOUS DISEASES— Continued ANTHRACNOSE. Attacks nearly all fruit and vegeta- bles in some form. It appears most fre- quently on the bean, attacking both pod and leaf. Cucumbers and melons are also favorite host plants. Its presence is indi- cated by unsightly spots on the leaf. Pre- ventive: Plant seed free from disease. Remedy: Spray plants when three inches high Avith Bordeaux Mixture (page 45) and repeat in two weeks and again after plant blossoms. Do not cultivate, walk through the rows or pick beans while wet with dew or rain. The disease is easily spread in this way. APPZiE SCAB. This disease shows itself early. A cold, rainy season is most favorable for this scab fungous. It can easily be determined by the almost black, dark-green, circular fuzzy spots on the fruit. The infected fruit many times drops before maturity, sometimes cracks open and is often badly out of shape. P r e V e ntive : * ^ Spray with Sterl- ing~worth Zi i q u i d Bordeaux ( pa g€ 45) as the buds open and again just after petals fall. Use Sterlingrworth Ar-Bo (page 48) at this second applica- tion and with one spraying get after both the codling moth and apple scab. Sterling-worth Ziinie and Sulphur Wasli (page 46) may be used as a substitute for Bordeaux. BZiACK KNOT. This disease at- tacks the plum mostly. Swellings on the limbs and twigs appear like bunches of hard, rough black warts. Remedy and Preventive: We know of no sure remedy or preventive but believe Bordeaux sprayings are helpful. Look the tree over when leafless and cut off all knots and burn them. *See qualifying statement regarding all of Bordeaux and Copper Mixture pages 44-45-46-47. Anthracnose on Pea Pod $TERLINe CHEMICAL CO., CAMBRIDGE, MASS. Page thirty-seven FUNOOT7S SZSSASES — Continued BiCISTER BUST: This is a clisea,se of the white pine and other pines v/ith needles in groups of five. The disease is native to Europe but was introduced into the United States several years ago on infested pine nursery stock. It has now become established in this country and offers a serious menace to the growth of white pine. The fungus parasite re- quires two host plants to com- plete its life cycle, the pines mentioned being one host and currants or gooseberries the other. The disease developes in the wood of the pine from spores from infested currant or gooseberry plants, upon which only the leaves are at- tacked. The disease once started in a pine gradually kills the parts attacked and eventually the tree itself. The fungus fruits in the spring, usually in April or May, upon the pine and breaks out as small orange colored patches surrounded by a white papery envelope. These orange spores are blown about by the wind and in turn infect any currant or gooseberry plants which happen to be within several hundred feet, causing a brown- ish rust upon the under side of the leaves. Thus the cycle continues. One pine cannot infect another. The disease must spread to currants or g'ooseberries and then liack to pines. If you know of or suspect the existence of this disease either on your own premises or the premises of others, communicate Fig. 1. — Diagram indicating the life circuit of the causal fungus of the white-pine blister rust, a. Blisters on pine in May and early June, from which the disease spreads to cur- rant or gooseberry leaves and produces the early summer stage, b; thence it may spread to another currant leaf and produce there a second crop of the early summer stage, c, or it may produce the late summer stage, d; in this stage, in the fall, it infects neighboring white pines, which may or may not include the pine (a) which bore the blisters that started the outbreak the preceeding spring.

Infected twigs, branches, and the trees themselves, m severe cases, should be cut and burned BBOWN SPOT. This disease seems to attack the Bald- win exclusively and m.ake the fruit look as if specked with small rotten circular spots. To Prevent:* Spray with Sterling-worth Bordeaux the same as for Apple Scab. CANXEB. This disease attacks nearly all fruit trees, and should be given prompt attention as soon CANKER/j^ as it appears. OSJ iM Remedy: When it appears scrape off all APPLE mi loosened bark near the seat of the trouble. Cut TWIG ^l out and burn small branches affected. Cover wounds with melted asphaltum after first disin- fecting with corrosion sublimate solution 1 part to 1000 parts water and dig out the canker sores. We know of no reliable preventive measure. CHESTNUT BI^IGHT. This disease, also of foreign origin, has for a number of years been killing thousands of chestnut trees in Eastern United States. The infection is spread from tree to tree by the agency of the wind, birds, insects. It will probably be years before this disease runs its course, and it is hoped that in time a variety of chestnut resistant to the disease will be developed and thus prevent this valuable tree from being exterminated. Control: Nothing can be suggested other than to cut and utilize chestnut timber as soon as a tree shows evidences of the disease. DOWNY MIZ.DEW AND BBOWN ROT. When this dis- ease attacks fruit it is called Brown Rot, and when it attacks leaves — Dov/ny Mildew. As Downy Mildew it attacks melons, cucumibers, squashes and grapes. You can detect it by the mouldy yellow spots on the underside of the leaves. These spots after a short time turn brown. The leaf wilts, dies and drops to the ground. When the disease appears get busy. A few hours' delay may mean the difference between a crop and no crop. ♦See qualifying statement regarding' all of Bordeaux and Copper Mixture pages 44-45-46-47.

Crinkley, puckered leaves, taking a powdery ap- pearance later on, is indicative of this disease. The leaves turn yellow and fall to the graund. As a preventive we rec- ommend Sterlingworth Iiiine and Sulphur Spray (page 46) early in the spring before the opening of buds. Some growers prefer Bordeaux sprays. PEACH YEi:.I.OW. Fruit from trees infested generally ripens early and has reddish-yellow streaks run- ning from skin to the pit. Peculiar yellowish sickly shoots sprout from the old wood. This is an extremely contagious disease for which no cure is known. Burn the tree where it stands and scatter lime liberally on the ground covered by the tree to kill spores and disinfect the soil. Be particular to burn trees where they stand. You may distribute the disease if you move them. Remem- ber this is as contagious among trees as small-pox is among human beings. POTATO EABI;Y BIiIGHT.

This disease shows itself as a whitish mold on the under side of the leaves. When j^ou see this look out for rotting potatoes. Use the same preventive for this as for Early Blight. Spraying potatoes for fungus costs nothing, as the increased crop pays liberally for time and materi- als. Spraying is part of "the game" the same as hoeing-. Buy your ma- terials when planting so as to have them on hand. This applies to both the gardener with fifty hills and to the large raiser with fifty acres. Shot-hole Fungus on Plum Leaf POTATO SCAB. STCRLINa CHEMICAL CO., CAMBRIDSE, MASS. This causes roug-h, scabby potatoes. It is usually prevented by soaking the seed in Sterling-worth No Scab (page 61). Never plant potatoes on soil that has raised scabby potatoes. Never use seed unless you sort it. The addi- tional crop more than pays for the trouble and expense. SOOTY SPOT. Looks something like Scab but Is not so fuzzy, more like an ink spot or paint stain and makes the fruit dirty. We do not know of a certain remedy but believe a spraying with Bordeaux when the fruit is about one-fourth grown helps. Attacks apple mostly. SHOT-HOI.E FUNGUS. This is a very destructive disease to the plum. This same fungus attacks the cherry. It sometimes completely defoliates the tree and practically ruins the fruit. Remedy: Spray with Sterling-- worth Iiiquid Bordeaux when leaves are half grown and again in two weeks.

Page forty-three BORDEAUX MIXTURE WHAT IT IS A?TD ITS USE 4 © OBDEAUX MIXTURE is a fungicide, made by com- bining- the Milk of Lime witli Copper Sulpliate. It derives its name from having been first used in or near the city of Bordeaux, France, and is considered by many the most reliable and effective remedy for most fungous diseases infesting vegetation. The value of Bordeaux Mixture cannot be over-estimated. T!ut it musl be properly prepared from suitable materials. Some recommend the use of equal parts of Lime and Copper Sulphate in malting, but we believe that most authorities rec- ommend the use of a quantity of Lime slightly in excess of the Copper Sulphate, especially if it is to be used in com- bination with a poison. Its use prevents or controls certain Scab, Leaf Spot and Sooty Mold of the apple, Anthracnose of the' Bean, Black- berry. Raspberry and Grape, Leaf Spot of the Beet and checks the ravages of the Flea Beetle, many of the Rusts, Leaf f'>]ights of Currant and Gooseberry, Celery, and Pear Blight. Downy Mildew of , the Cucumber, Melon and Squash. Potato Blight, Black Knot. Shot-hole fungus; also many Fungous Diseases, Blights and Leaf Spots that attack Shade Trees. Primarily it is a fungicide, but when combined with a l)oison, as Paris Green, Arsenate of Lead, London Purple, cal- eium arsenate, etc. (see Sterling-wortli Ar-Bo page 48), a val- uable mixture is obtained which in addition to the fungicidal properties kills and controls Bud Moth, Canker Worms, Codlin Moth (which make your apples wormy) Curculio motli, Aspar- agus Beetles. Cabbage Worms, Slugs, Currant Worms, insect attacking Cranberries, Striped Cucumber Beetle, which at- tacks your Squash, as well as Cucumber vines, Squash Bugs. Flea Beetle on Grape and Potato vines. Rose Bug, Potato Beetle (potato bug), etc. It may be used as a liquid or Dry Powder. We believe the liquid form is the best for most purposes. It is a compound of remarkable adhesive properties. When it becomes dry on tlie foliage, it resists excessive washings of rain for some time. Bordeaux is a remedy and it is for use as a preventive rather than a corrective. One thorough spraying at the right time is worth more than ten careless treatments. Almost any of the spray pumps will do the work satisfactorily. The spray should be sent against the vegetation in a fine mist with some force. If a spray pump is not available, it may be applied with brush and pail.

STERUNOWORTH , STnUilCVirOR'VM , '^Mm FOB CERTAIN FUNGOUS DISEASES It may be combined with a poison when de- sired (full directions are on the can), so combined it becomes a combined Fungicide and Insecticide, and kills many eating insects as well as remedies most fungous diseases, but for a combined insect killer and fungous remedy we recommend Sterling-worth Ar-Bo (See page 48). The selection of materials used in the manufacture of Sterling-worth Iiig.uid Bordeaux is made with great care, and the resulting combination has given satisfaction for over 10 years. Careful selection of materials and great care in its preparation are essential to greatest success. The kitchen gardener and small groAver will find it more satisfactory to buy his Bordeaux ready to use than make it himself and many large users find that it is cheaper to buy the ready- made material when he figures the cost of the labor and the utensils spoiled in making it. Sterlingrworth Ziicitiid Bordeaux is about the consistency of putty or paste. One gallon makes from 10 to 50 gallons (de- . pending for what purpose it is to be used) of mixture ready to use by adding water. Explicit directions for use on every can tell hov/ to use it on each kind of vegetation. If you only have one grape vine or one fruit tree or a 100-square-foot garden you can afford to spray.

BORDEAUX MIXTURE What It Is and Its Use " (Continued from Page 44) of Bordeau.x Compounds do under certain climatic conditions cause rusting. Avoid using Bordeaux or Compounds of Bor- deaux except in settled weather. Sudden change in tempera- ture and damp rainy weather are believed to be favorable to Bordeaux injury. We believe that the injury likely to be done by Bordeaux to be less than that done by the disease against which it is used. Bordeaux should not be used on Japanese plum or similar tender leaved foliage. Its use on Melons and Cucumbers is sometimes followed by injury, but as such crops are generally completely ruined by disease, unless pro- tected, the beneficial results more than offset the injury done.

Cucumber plants are often seriously injured, and various ornamental plants are no less immune. Control. Recent experiments conducted at the Massachusetts Experiment Station have demonstrated conclusively that "Red Spider" can be controlled and injury prevented by a thorough application of I^inseed Oil Emiulsion.

We leave the matter of what constitutes satisfaction entirely to your honor, is that you use it as directed, grive it a g'ood, honest, fair trial. Guaranteed Cattle Oil is as good an article as we can make regardless of price consideration. Thousands of cans have been sold under the above "Money Back" guarantee and during the five years it has been on the market less than 10 cans have been returned. We claim that when properly used it will protect cattle all day in ordinary weather. It does not taint the milk and is not disagreeable to use. It is to some extent useful against lice on cattle and horses but we do not recommend it for lice, as any preparation strong enough to be a good lice killer will blister the animal if it is used for a fly spray. Guaranteed Cattle Oil may be used with a brush or sprayer. The Delug'e Sprayer described on page 60 is one of the best for applying. Guaranteed Cattle Oil does not depend for its effectiveness on killing flies but on the fumes and odor which arise from it. Flies hit by the fluid are killed, the others are kept off by the odor. Read what we say about flies on page 19. , These filthy in- sects spread disease and by continually annoying stock cause it to lose flesh and injure its health.

Dip a stick into a can of Sterlingworth Anti Crow Com Oil and stir it around in a peck of corn until the corn is dark- ened a little.

The oil will give it a thin crow-protect- ing coat, which is an easier and cheaper way of protecting your newly planted corn from crows and blackbirds than by "scarecrows." Do not confuse crow oil with so-called "Crow Tar" or corn tar. It is different in odor, and stronger. One trial will convince you.

We have manufactured Sterlingf- worth. Lawn Compound 6 years. It gives universal satisfaction. We guarantee tliat it will kill weeds such as plantain, dan- delions, chick-weed and most other weeds having a broad hairy surface without killing the grass. Money back if it fails. Sterlingrworth Lawn Compound is a non-poisonous dry powder for sowing on the lawn and adheres to the broad flat leaves of such weeds as those named above. It does not stick to the grass because of its upright position and smooth sur- face. The ingredients in combination with the sun's rays burn out the weeds. The compound has an invigorating effect on the grass, wliicli stimulated by it springs up rapidly and gets ahead of the weeds tliat have been stunted and killed by the compound and quickly cliokes them out. The use of Sterlingrworth Lawn Compound helps give to the grass a beautiful rich bottle-green velvety color so much admired by lovers of good lawns. Two applications will clean out the most heavily weeded lawn. In many instances one ap- plication will do it. Do not dig out weeds, it leaves bare spots and holes. Sterling-worth Lawn Compound is easily applied by sprinkling over the weedy lawn. One pound will dress 100 to 200 square feet, depending on the lawns con- dition.

It requires an entirely different method to rid poultry houses of mites than to kill lice on fowls. No powder is en- tirely satisfactory for this purpose, for these blood-sucking pests inhabit cracks and crevices in the building where it is impossible to reach with a fluid or powder, and it is neces- sary to depend upon a gaseous vapor to penetrate their hiding places. Read about lice and mites on page 35. Sterling'worth Iiiquid Xiice and Mite Killer has a double value. It kills bj" contact, and the vapor thrown off by its wonderful evaporating qualities helps kill certain vermin. Poultrymen who do not find mites on their fowls should not be led to the delusion that their houses are free from them, for they^ attack fowls when they are on the roost at night, suck their blood during the sleeping hours and hide in their retreats under the roosts or in crevices during the day. To treat a large number of fowls, apply liberally to nests, roosts, supports and dropping boards. For young" chickens. Paint the bottom of a box with the liquid and cover with a thin layer of straw.

Roup is one of the most common, most contag-lous and most fatal diseases v/hich afflict poultry. It frequently starts with a simple cold and if unchecked quickly spreads through the entire flock. The symptoms are odorous dis- charges at the mouth and nostrils followed by swelling of the head and quick breathing. The fowl has an offensive breath and canker spots sometimes appear. For years this terrible disease raged unchecked and killed millions of fowls. It can now be prevented and relieved with this remedy which is ad- ministered in the sick fowl's drink and in this way they take it. If the disease is so far advanced that the fowls cannot see to drink, tlieir heads may be bathed in the medicine until they have sufficiently recovered to drink. Use a little of this remedy in the fowls' drink as a preventive of roup, canker and common colds, and you will save much trouble. It is an excellent remedy for canker. Ask your dealer to get Sterling"worth Roup Renxedy^ "the-money-hack-the-no-cure-no- pay-kind."

The fellow who claims that egg tonics are useless and should not be fed to hens is the fellow you meet most fre- quently in the drug store buying- spring- tonics, cascara, quin- ine or liver pills. Careful inquiry will generally show that he believes in "dosing" himself, wife, horse, dog, cow and cat. but on the point of "heping- out" the hen he takes a dif- ferent stand. You will generally find that he bases his judg- ment upon the use of the old style filler eg'g foods which con- tained so much useless filler that a hen had to eat a bushel or so of filler to get one dose of medicine. By "filler" we mean bran, screenings, and other low-priced materials used to make the package look "a lot for your money." Sterling"worth Hgg Tablets contain no "filler" and if a tonic is good for man and domestic animals, why not the hen. These tablets are as larg-e as a five-cent piece and over an eighth of an inch thick and contain more egg-stimulating tonic value than is contained in a pint of many filler egg foods. They are used by dissolving in water or may be crushed into powder and given either in the fowl's drink or by moistening food with the water in which the tablets are dis- solved or mixed dry with mash foods.

Nothing cheers the sick more than flowers, and few things give so much pleasure to the housewife as her potted plants. Sterling-worth Plant Tablets were originated and first used by a chemist who loved flowers and made their care and attentior a "hobby." His plant-loving friends had such won- derful success with the tablets he gave them that he was induced to offer them for sale, and from this love of the beautiful and spirit of kindness, the present world-wide business in Sterling-worth Plant Tablets has grown. They contain those ingredients in their proper propor- tions that are necessary for healthy plant life. Their use promotes a luxuriant, vigorous growth of branch, leaf, and flower. Users have told us that they "double the bloom." Renewing of plant soil is made less important and is less frequently needed, when these tablets are used. They build up the soil, and supply scientifically the elements neces- sary to a wholesome growth. Sterlingrworth Plant Tablets are more effective than what is commonly known as "liquid manure," which contains much waste matter which pollutes the soil and is generally accom- panied by a disagreeable odor. Thousands of plant lovers who do not keep plants would do so they knew how beautiful and luxuriantly they could make them bloom by feeding with Sterlingrworth Plant Tab- lets. To those who have plants that are not as beautiful as they should be we say, "try these tablets just once, the cost is trifling, the results wonderfully satisfactory." When you learn how satisfactory they are, you will buy more. They are used by dissolving in water and watering the soil with the solution. Tell your plant-loving friends about them. They are sold by thousands of florists, druggists, seedsmen and agents throughout the United States and Canada. Agents who can devote a little time to selling these tablets will find the profits satisfactory.
