REPORT OF DIRECTOR. Dr. W n. LeRoy Broun, President: SIR-I have the honor as Director of the Station to submit the following report concerning the work under my charge during the year 1901. 'The steady increasing popularity of the Station and its work .among the farmers of Alabama is gratifying, and there are constanit demands made on the office for bulletins relating to such subjects as are of 'special moment to the material advancement of Alabama agri- culture. Letters have reacheld the Director's office dur- ing the year 'askinig for information on topics relating to or;chards, the lands and fertilizers suitable for the successful cultivation of corn, cotton, grass, and other forage plantis,, how to save hay, and the best plants adapted ito making pastures; how to feed for beef and milk 'an.d butter, 'the best breeds of stock for this cli- mate, and how t'o take care ,of 'the fine grades of stock. Parties living in other sections of the country north of us have written many letters asking for all kinds of in- formation concerning the State. In what portions are the best lands located for fruit, raising hogs, market gardens and the opportunities, for successfully cultivat- ing anid ,disposing of all kinds of vegetables, the cli- mate of the State, and numerous other like questions which bear on the subjects of farming and the develop- ment of homes. The in'creasing demand for information on stock and the making of hay is exceedingly encour- aging, and is a hopeful sign th'at the farmers are real- izing at least the great advantage of diversified indus- try, and the hopelessness of depending on the one crop system. Most of the earlier bulletins relating to foi'- age plants and to stock have been exhausted, and the demand has not been ,4atisfied. There are many let- ters on file in the Director's office speaking in high terms concerning the estimates the farmers place on the results of ithe work of the Station for their benefit. They appreciate the fact that certain results of the long conducted experiments at the Station have been the means, of saving them many dollars, and the pasit year they have read the bulletins more generally than in any year since the estallishment of the Station. The emailing list has rapidly grown during the year, and in a lmost every mail letters come asking for bul- letins, and to have names added Ito the list. The policy of the Station has been not to burden the mailing list with names simply to scatter the bulletin's, but we have carefully avoided placing any name on 'the list unless specia.lly requested ito do so. The number of parties who are now regularly receiving the bulletins of the Station is 8,933. The mailing list being encumbered with many names of parties who were either deceased or removed, it was decided to make a revision of the same. Accordingly postal cards with return slips were sent out notifying ithose to whom they were addressed that the mailing list was being revised, and requesting that if they wished to continue to receive the bulletin's to so indicate it by reiturning the attached card, with their names and addresses. Some years having elapsed since this matter was attended to, the revision caused quite a reduction in the number of names, due to the death of the parties in many in'stances, 'and to the changes in post offices o'f a number of others who for- merly received the bulletins. There were something over 1,500 names dropped from the mailing list because of this revision. During the year there have been added 332 to the mailing list 750 names from Alabama and abroad. M'any of the earlier bulletins of the Station have been exhausted some time 'ago, and a number of the moee recent ones have been greatly reduced, and at the pres- nt rate of demniand they will also become exhausted very soon. I would .advise, therefore, an increase in the numbers printed of each bulletin. The following synopsis of the bulletins issued dur- ing 190.1 indicaltes the character of the experiments conducted by the Station staff during the year: LIST OF BULLETINS WITH CONTENTS ISSUED BY THE STA- TION IN 1901i, COMPRISING VOLUME IX. 113-CO-OPERATIVE EXPERIMENTS WITH COTTON IN 1899-1900.

The following changes have taken place in the per- sonel of the Station since the last report: Prof. . S. Earle, the Biologist and Horticulturist, resigned the first of August to accept a position in Columbia University of New York, and his place has been filled by the election, October 1st, of Dr. E. Mead Wilcox, who occupied the chair of Botany in the Agri- cultural and Mechanical College of Oklahoma. J. Q. Burton and H. S. lHoughton, Assistant Chenists, have resigned to 'accept positions elsewhere, and Thomas Bragg has been appointed to the post of Third Assistant Chemist. G. F. Freemnan and . J. Lide were appointed Assist- ants to the Director September 15, 1901. P. H. MELL, Director. BOTANJCAL EXPERIMENTS. Dr. Wm. LeRoy Broun, President: The experiments concerning grasses,'cultivated, native and foreign, have been continued, and a large number of species have been added to the collection, growing in the Botanic Garden. A large number of shrubs, ever greens and other trees, native and 'foreign, were planted in the Arboretum during the year. And many varieties of forest seeds have been planted for future experiments in forestry. 335 The experiments :on the improvement of the cotton, vhich have been under way for a number of years, vere continued during the past season. P. H11. MELL, Botanist. REPORT OF CHEMIST. Dr. Vmn. LcRoy Broun, President: SIR-The report of Dr. J. T. Anderson, Acting Chem- ist of the Station, up to September 1, 1901, covered the work of the year up to that date, at which time I resumed my duties as Chemist of the Station. During ,the past few months, the time and attention ,of the laboratory staff has been devoted chiefly to mis- cellaneous analytical work, including the examination ,of soils, marls, n atural phosphates, waters, ores, mis- cellaneous minerals, etc. A considerable amount of valuable analytical work has been performed by Mr. Hare, First Assistant Chemist, in connection with his duties as Referee on Potash for the Association of Official Agricultural Chemists, and some important results have been se- cured which will no doubt lead to improvement in the existing method of analysis. Work upon the analysis of samples of forage crops grown at the Station is in progress at this time, and this department has also recently made a considera- ble numnber of tests of varieties, of lard produced at the Staition with a view of noting the influence of cer- tain foods upon the character of the lard produced. Mr. Phelps, one of the laboratory assistants, has in progress a series of experiments to determine to what extent nitrogen compounds are leached from the soil 336 by ,the winter rains. .,This question is quite an im- portant one for investigation, as the soils in this section by reason. of being denuded of vegetation during the winter-month's, are liable to suffer greatly from continuous exposure to the leaching effects of ithe rains prevalent at this season. It is, therefore, hoped that some results will be secured which will throw some light upon the character and extent of the losses sus- tained by the soils through leaching processes. During the present year, it is designed to pursue the study of ,several i'mportant questions-among oth- ers, a further investigation of the normal constituents of the sugar cane, this being a continuation of a line of work commenced several years ago. During the absence 'of the undersigned in Europe, sev- eral Experiment Stations and Station Laboratories were visited and inspected with a view to securing in- formation with regard to their methods of investigation, methods of analysis, their equipments, apparatus, etc., and some interesting notes and data were obtained for use in Station work. My thanks are due Dr. J. T. Anderson for his care- ful and efficient conduct of the work of the Department during my absence in Europe. Very respectfully, B. B. Ross, CheMist. REPORIT OF ASSOCIATE CHEMIST. Dr. Win. LeRoy Broun, President: SIR-I have the honor to submlit herewith my report for the year 1901. During the first eight months of the time embraced in ithis report, viz., from January 1, to August 31, in- clusive, the Associate Chemist was Acting Chemist of 'the Station, the Chief Chemist, Prof. B. B. Ross, being absent .on leave. During this time the chemical staff was occupied chiefly with the fertilizer work. Eight hundred and fifty-one samples of commercial fertilizers were received from various sources and analyzed. and in August the results of these analyses were issued as Bulletin No. 15 by the State Department of Agriculture, and a limited number of these were bound in the covers o!f the Station Bulletins and issued by the Experi- ment Station as Bulletin No. 115. In addition to the fertilizer work, a considerable num- ber of miscellaneous analyses were made for the other departments of the Station, chiefly the Agricultural De- partment, and the results were published in the bulle- tins issued by these departments. These include analy- ses of samples of peavines and roots, stable manures, soils, butters and lards. Since October 1 the Associate Chemist has been oc- cupied exclusively with some experimental w'ork which he has undertaken jointly with Prof. Duggar, viz.: A Study of the Sources from which Leguminous Plants Derive Their Nitrogen. This work has been in progress for two seasons, 1900 and 1901, and was done in .the vegetation house. Some fifty odd metal pots contain- ing different kinds of soils with several kinds of fertil- 338 izers were required for the experiments. The chemical data to be furnished by the writer are: the nitrogen 'contenit of each p o;t of soil as it was prepared for the plants in the outset; the amount of nitrogen added in the seed in planting; the amount of nitrogen added with the water used for watering from time 'to time throughout the season; the amount of nitrogen in the harvested crop, both vines and roots, from each pot; and, finally, the nitrogen content of the soil in each pot after harvesting. With these data it is easy to de- ter-mine, how mu.ch nitrogen the plants have gotten from the soil and how much from the atmosphere. Owing ,to preoccupation with other duties, the greater part of this analytical ,work ifor the season o'f 1900 had to be 'deferred, and has been done since October 1 last, 'and hence is embraced in this report. All the data for 1901, also, will shortly be ready, when it is intended to ,offer the results o;f the two season's work together for publication in bulletin form. Respectfully submitted, JAS. T. ANDERSON, Associate Chejmist. REPORT OF VETERINARIAN. Dr. Wum. LeRoy Broun, President: SIR-The following constitutes a brief summary of the work 'of the Veterinary Department for the year ending December 31, 1901: Farmers Institutes were held in the following towns and counties: Columbiana, Shelby county. Jacksonville, Calhoun county. 339 Greenville, Butler county. Fruithurst, Cleburne county. Vinemont, Culliman county. Th'orsby, Chilton county. Seale, Russell county. Union Springs, Bullock county. Clayton, Barbour county. Ozark, Dale county. Geneva, Geneva county. Andalusia, Covington county. Athens, Limestone county. Hartselle, Morgan county. Cullman, Cullman county. Ashville, St. Clair county. Collinsville, Dekalb county. Center, Cherokee county. Arlington, Wilcox county. Grove Hill, Clarke county. The total attendance at these meetings was 1,028. The average attendance at ea:ch meeting was 51. As far as pos,3ible the institute forces were divided in order that more places might be visited. At the three fruit growing centers, Prof. Earle held meetings by himself. Prof. Duggar, with three helpers, held six institutes in the southeastern part of the State. Wi Aith two assistants, I conducted 'the other eleven in'st itftes that were held during the year. Profs. Duggar, Earle, Hare, Austin 'and Clarke of Auburn have all done efficient and faithful work in 'many of these institutes. The attendance is not as large as it should be; yet the great majority of those Who do attend are interested farmers. In every instance where institutes have been held a second time the attendance and interest have improved. The territory covered this year embraces 440 nineteen different counties of Alabama; five more than in any previous year without an increase of funds. Bulletin No. 116 was issued by this department in September, 1901. It embraces. the causes, symptoms, 'diagnosis and methods of producing immunity to Texas fever. The results of the defibrinated blood method of immunizing northern bred cattle to Texas fever, at this Station and others, 'are given in this bulletin, The newer and later methods of immunizing cattle to Texas fever have proven very 'successful. In fa'ct they can be employed with safety and profit. In all cases where requests h ave come to the department I have inoculated 'susceptible cattle, charging only my actual expenses 'for the work. This department has furnished tuberculin of its 'own production to 'all cities and veterinarians in the State, who h'ave applied for it and agreed to report the re- 'sults of 'the tuberculin .teststo the department. Search is being continued for the cause of osteo- porasis (big-head) in horses and mules. Also investi- gations are being continued to determine why cotton seed and cotiton seed meal are poisonous to pigs. Rec- ords of the occurrence and search for the cause and treatment of infectious cerebritis have been continued during the past year. As far a's possible records of all diseases that occur among farm 'animals are collected in .order that the department may be in touch with the diseases that are peculiar to certain districts of the State and to certain seasons of the year. Respectfully submitted, C. A. CARY, Veterinarian. REPORT OF THE AGRICULTURIST. Dr. Win. LeRoy Broun, President : SIm--I respectfully submit ithe following report of the work of the Agricultural Department of the Ala- bama Agricultural Experiment Station for the past year: Three bulletins have been issued and the prepara- tion 'of three others has 'been begun. The ititles of the bulletins published are a's follows: No. 111.-Corn culture. No. 113.-Co-operative experiments with cotton in 1899-1900. No. 114.-Feeding experiments with dairy cows. The work of the department with field crops has been chiefly along the lines previously reported. However, the work in animal husbandry has 'been extended as far as our means permitted. The experiments with ani- mals conducted during 1901 consisted of- (1.) IComparison of a farm-grown versis the oil- mill's ration for dairy -cows; (2.) The substitution of vetch hay for wheat bran in order to cheapen the ration of dairy cows; (3.) Experiments with calves of the beef breeds to determine the cost of producing beef and to compare corn meal with rice meal; (4.) Records of the growth made and of the food eaten by the different individuals of our herd of beef cattle to secure data on the cost ,of growing beef cattle; (5.) Records of the amount of milk and butter and 'of ithe 'food consumed by each cow in our dairy herd, so as to determine the cost of producing butter; (6.) The substitution of cotton seed oil for butter fat in the food of young calves; .442 (7.) A continuation of the experiments in pork pro- duction, including (a) grazing experiments with pea- nuts and sorghum, (b) methods of hardening the flesh and lard of pigs. which have grazed on peanuts, (c) effects of feeding cowpeas, c'o'wpea hay, and cotton seed meal to pigs. In the dairy Mr. R. . Clark has made an important disceovery of 'a means ,of getting rid of the bitter-weed flavor in cream and butter. He has also done some work to determine the degree of acidity at which cream from cows fed on cotton seed can be most advan- tageously 'churned, the propelr richness or thickness of cream for most thorough churning, and has made care- ful observations ,on the effects of our common foods on the quality of butter. In field work a number of experiments have been con- ducited with o'tton, corn, oats, and w'heat. Most at- tention has been given 'to corn. A number of forage plants have been under test, cow- peas and sorghum having the most prominent place in our experiments. In our co-operative 'soil tests, intended to learn the fertilizer requiremen'ts of the principal soil !tests of the State, cotton has 'been, as hereitofore, the principal test crop; however, this fertilizer 'test has, in a number of localities, been made with corn also, and, ip a few in- 'stances, wheat and Johnson grass have been the crops employed in determining the 'seeds of the 'soil. During the past year the writer hals conduceto ,e usual large correspondence and has partLdpated in as many of the Farmers' Institutes as possible. Respectfully submitted, J. F. DUGGAR, Agriculturist. REPORT OF THE BIOLOGIST AND HORTICUL- TURIST. Dr. 1V7,W. LeRoy Broan, President: SiRt I have the honor to submit herewith the follow- ing report on the operations of the department under my direction. The prophetic character of this report finds its cause in the fact that my connection with this in- stitution dates from 1 October, 1901, only. In the Horticultural Department my assistant, Mr. C. F. Austin, has prepared f or publication as Bulletin 117 a paper entitled "Orchard Notes." It is evident that ,these notes, detailing the results of the compara- tive tests of many varieties in this region, will prove of great value to persons engaged in, or about to en- gage in, fruit culture in our State. It is the desire of this department to foster and encourage in every man- ner possible the rapid development of the horticultural interests of our State. A valuable preliminary step in this direction will have been taken when, a's a re- sult of variety tests of a very extensive character, we are able to give specific information regarding the pos- sibiiity of growing orchard and garden crops in the various parts. of the State. As Vegetable Physiologist and Pathologist, I have indertaken a very extensive study of the general physi- oli and pathology of the many leguminous forage plartP gron in Alabama and other States. Several points regarding the biology of the organisms producing the tubercles. on the roots of these plants are receiving attention. It is my intention to make 'a thorough study also of the diseases 'of these plants. For the elucida- 344 tion of all these points, extensive growing collections of th.ese plants will be maintained this season. Several important additions to our Herbarium were made during the past year. In the future my attention will be concentrated upon the State flora for the pur- pose of building up here a. State Herbarium that shall be fully representative of the interesting plant cover- ing of the State. For this purpose much time is now being devoted ,to the preparation of a card index of all our collections in the State Herbarium. Each one of th.ese ,cards bears a county map of Alabama, so that, for each species, the geographical distribution over the State, so far as substantiated by our oown ceollection, may be plainly indicated. This index will serve to indicate the profitable lines along which floristic and ecological work should be conducted over our State. Respectfully submitted, E. MEAD WILCOX, Biologist and Horticulturist.
