The experiment station of the A. & M. College was established under State law in the summer of 1883. An exhausted farm of 226 acres was purchased to be used for the purpose. Much of it was turned out on the commons ; the build- ings and fences on the remainder were in a very dilapidated con- dition. A large portion of the land had been abandoned for cul tivation on account of its poverty and gullied condition. Under these circumstances, with only one official connected with the Station, the Director, who was also prof, of Agriculure, progress in development was slow , especially since the funds ap- propriated to the Station were small in amount Notwithstanding these difficulties, considerable progress has been made in some departments of the work, — especially is this true of the Horticul- tural department. Field experiments have been conducted each year, and bulletins furnished the Department of Agriculture for publication, as re- quired by law. The equipment, so far as machinery and improved impliments are concerned, has been, until now, inferior to that of an ordinary well conducted, private farm. Much time 5nd labor have been expended in clearing up pine thickets, tilling gullies, building fences, and arranging for a supply of water under pressure. The only experiment, so far, conducted with cattle, has been that of intense inbreeding with thoroughbred Jerseys — This has been continued for four years, under careful supervision, with apparently favorable results. Besides experiments already completed, a large number are now in progress in field, orchard, vineyard, and garden. The cotton plant has been made a subject of special inquiry, both as to its development above ground, and its root growth. Similar inquiries have been made with regard to the corn plant In both, varieties have been compared, inquiries made as to the fertilizers best adapted to their growth upon the soil of this Station, and with the additional facilities which will now be sup- 6 plied through the Congressional appropriation, inquiries will be multiplied and carried to much greater detail. The experiment work upon the Station is divided into two gen- eral classes : First, The demonstration of facts already known to the ad- vanced agriculturist, but not generally disseminated. Second, Original investigation having for its object the dis- covery of truth. So far as the study of plants is concerned, in- vestigations will be made first upon the most useful and gen- erally cultivated plants in the Southern States. Feeding experiments will be principally confined to inquiries looking to determining the nutritive value of peculiarly southern crops, and their digestibility. Besides the experiments reported on the following pages, inquiries are in progress with reference to cotton, corn, sweet potatoes, tobacco, forage plants, ground- peas, sorghum, wheat, and in the orchard, pears, apples, plums, peaches, figs, quinces and cherries. All of these have been planted in considerable variety for the purpose of ascertaining which varieties are best adapted to this soil and climate, as well as to record the characteristics, both as to vegetation and reproduction of varieties. The diseases affecting the different species of fruits and vines, as well as their enemies amongst birds and insects will be sub- jects of special investigation. Fifty-eight varieties of grapes are being fruited £nd propagated, sixty varieties of strawberries, and twenty-nine of raspberries. The soil of the Station ie principal^ either sandy or pebble drift, mostly with clay sub-soil generally beyond the reach of the plow. There is, however, sufficient area of clay subsoil within reach of the plow to vary the investigation so far as soil is con- cerned. The soils of the Station, therefore, represent a large area of the State of Alabama ; a portion of which lies above the prairie region extending nearly across the State, but a still larger area lying be- tween the prairie belt and the gulf. In order to investigate the properties, physical and chemical, and the needs of typical soils throughout the State, ten such soils have been collected from the virgin forests, keeping the soil and subsoil separate and replacing them in their natural relative posi- tion in bins prepared for the purpose and placed under identical circumstances. Each soil and subsoil is being subjected to chem- 7 ical and mechanical analysis in the laboratory, and plant analysis in the field. Each soil and sub-soil is divided into eight parcels and placed in as many bins. The cotton plant is growing in each bin. To these has been ap- plied different elements and combinations of elements of plant food for the purpose of inquiring which of these elements are • needed by each particular soil. This will be repeated from year to year until a sufficient number of tests have been made to eliminate the variable factor of climatic influences resulting from difference in seasons. Additional barns, silos, offices and working rooms are being sup- plied, and a complete outfit of improved machinery and farm im. plements has been purchased. It is proposed to test by.the Dynamometer the draft of different tools and machines, and manufacturers will be invited, at a stated period each year, to send to the Station specimens of their imple- ments, plows especially, to be carefully and accurately tested, and the results reported in the Station Bulletins. A new and complete laboratory building is now thoroughly equipped for work in the chemical department. A complete meteorological outfit has been purchased, and microscopes ordered for thorough work in investigation of the secrets of animal and vegetable life especially the fungi injurious to useful vegetation, as well as the habits of insects, friendly or, injurious to vegetation. A Creamery will be equipped during the present year, with the best modern appliances by means of which the most approved methods of handling milk and butter will be demonstrated, and, in connection with that department, feeding experiments with special reference to milk and butter production will be conducted. The Experiment Station being in immediate connection with the college grounds, the members of the agricultural classes have exceptional opportunities for acquiring familiarity with its work and of becoming acquainted with methods of scientific investiga- tion. The Station was re-organized under the act, known as the a Hatch Bill,” to take effect the hirst of April. It came too late for the inauguration of new experiments in the held or garden. The following results are from experiments commenced under the old organization and completed since April 1st : 8 Experiments With Table Corn. — Object — To compare earliness of varieties.

In soil analysis, the methods published by the Department of Agriculture at Washington have been strictly followed, and great care has been taken to secure accurate results. While soil analy- sis has, of late years, fallen somewhat into disrepute, on account of hasty conclusions drawn from imperfect data, and a want of thorough study of all the conditions of plant growth, it has an im- portant value in the scientific investigation of the productive ca- pacity of soils and the means best adapted to restore fertility and to prevent exhaustion. In accordance witjj the plan of experimentation agreed upon for the Station, representative soils with sub-soils from different portions of the State have been collected which will be analyzed ith great care, and their productive value with and without fer- tilizers, determined by carefully conducted and accurate experi- ments at the Station. Important conclusions, it is believed, will be drawn from these results, not only of general scientific value, but of practical utility to the agriculturists of Alabama and other states. The results of soil analysis thus far completed are as follows : RESULTS OF ANALYSES OF AIR-DRIED SOILS AND SUB-SOILS. — SOIL RECEIVED FROM AGRICULTURAL EXPERIMENT STATION. 1 Virgin Soil.

H. MELL, BOTANIST. So short a time has elapsed since the organization of the Experiment Station, but little can be said of the Botanical work. An outline of some of the plans proposed, however, may not be amiss here. The investigations in this department were intended by the laws establishing the station to cover the entire state. In other words it is contemplated to write in popular language a botany of Alabama that will be equally intelligible to the farmer and valuable to the scientific student. This will not be the work of a few months, nor will it be accomplished by one person. But it must be the work of years and through the combined efforts of the earnest farmers of Alabama and the officers of the Experiment Station. As we look over the field before us it seems best at present to divide the work as follows: 1. The Classification and determination of the relative econom- ic values of all wild plants useful for forage and other like agri- cultural purposes. 2. The classification of all noxious weeds and a discussion of the best and cheapest methods of eradicating them. 3. The medical plants of the State. 4. Trees and shrubs that are suitable for lumber and building interests. It will also be a matter of importance to examine these wild plants while under a state of cultivation and thus prove their adaptation to the wants of the farmer. Valuable assistance in the prosecution of this work may be rendered by the farmers of the State if they will send specimens of plants to the Station carefully collected in the following man- ner: 1. In the case of an herb or grass the entire plant must be sent including roots, stem, leaves, flowers and, if possible, the fruit also. Select fifteen or twenty vigorous, well grown specimens and place them between sheets of thick unsized paper, taking care to spread the leaves and adjust the flowers so that the small- est proportions of parts are not folded and bent out of shape. Place a pressure of 30 or 40 lbs on the paper and place aside to dry When the plant is too long for the size of the paper, bend the stems until reduced to proper proportions. 26 2. Take careful notes of the plant surroundings. The charac- acter of soil, whether found on up land or loyr land, moist or dry- land, foreest or open field, time of flowering and seeding, etc., height of plants. State whether the plants are in large or small nnmbers. Are stock known to eat them, etc. 3. In case of large trees and shrubs it will be best to take sec- tions of the trunk and collect the leaves, flowers and fruits. The sections must be cut ten inches long and the bark left on un- bruised. These specimens should then be numbered and careful- ly packed in strong boxes and shipped by freight to the station at Auburn. Notes must be taken concerning the tree, where it is found, kind of soil, common name, if known, and if it has been used for any special purpose. Place a number on the note corres- ponding to that on the section. Send the notes by mail to Au- burn. The leaves must be pressed between paper as already de- scribed. 4. In sending specimens through the mail or by express do not roll the papers but pack them spread out as they come from the press. Lay the sheets containing the plants one on top of the oth- er, place at the top and bottom of the package stout paste board. Wrap all with strong paper and address to Experiment Station, Auburn, Ala., (Department of Botany.) In every shipment send notes, name and post office. The grasses are best collected between the first of May and the first of October. Many plants mature their seeds by the first of June, and they must be collected early in the spring just as soon as the flowers are formed well.

Observed on 3d of January, 1887, at Livingston. Minimum Barometer, 28.955. January 3d, 1886, at Auburn. First killing frost in fall in North Alabama occurs between the eighteenth of October and sixteenth of November. In Middle Alabama it occurs between the twenty-fourth of October and twenty-sixth of November. In South Alabama it occurs between November seventh and twenty-fifth. During a period of seventeen years (1871 to 1888), the highest recorded summer temperature was 109 degrees, which occurred at Livingston on the sixth of June, 1885. 31 The lowest recorded temperature during the same period was seven degrees below zero at Gadsden, on the eleventh of January, 1886, making an absolute range within the seventeen years of 116 degrees. These were exceptional periods, however, because, comparing one year’s average temperature with averages of oth- er years, we find there is only a range of 2.8 degrees, thus indi- cating that the climate of the State is mild and uniform ; no verv great extremes.
