 (\ V. Adams, (lie t'iit()iiM)l()<ri.sl. who had Ix'i'ii actiiiu: director, was 

 eli'i'tod to the direetorshi|) at the close of tlie year. The newly ap- 

 pointed a<2:r()noniist. Maitin Nelson, took up his work at tjie station 

 in Oeloher. A dill'erentiation of the college and station has been 

 made, and the State has jjrovided more definilely for extension and 

 farmers' institute work. 



^^'ork on the Achims fund i)rojects outlined in previous reports, 

 exceptinii- the one relating- to anthrax and anthrax vaccines which 

 was completed last year, was carried forward and generally satis- 

 factory proifress was made. The study of the cattle tick with refer- 

 ence to its life history and its relation to the germ of Texas fever 

 has been sufficiently pursued to obser\e to a considerable degree the 

 route followed by the fever germ in passing from the adult to the 

 young tick. Data in connection with the investigations on the loss 

 of soil fertility in fruit growing and on the toxicity of cotton-seed 

 meal are increasing. The results thus far secured in the apple-twig 

 l)Iight project point to a possible relation Iwtween the amount of 

 starch in twigs and the blight. In the hog-cholera project, data 

 with reference to the age of the bacilli as related to their virulence, 

 duration, and means of infection, etc., are accumulating, and the use 

 of serum from hyperimmunized cattle as a curative and preventive 

 of Texas fever is receiving continued attention. 



The work carried on by the station with other funds includes soil, 

 fertilizer, rotation, and cnlture tests wnth different crops, plant breed- 

 ing with wheat, oats, barley, rice, and corn, tile draining, cooperative 

 orchard spraying, and forage-crop investigations. The results of 

 the tile-drainage tests show the benefits of tile at certain depths and 

 distances, and the experiments on the effectiveness of sprays have 

 led to the determination of the minimum strength of Bordeaux mix- 

 ture and arsenate of lead and of the jjroper strength of l);)ilo(l and 

 self-boiled sulphur and lime solutions. 



The department of entomology studied certain details in the life 

 history of the San Jose scale with reference to sunmier treatment 

 and made observations on plant lice to determine their relation to 

 blight and other diseases. A bulletin of information on the San 

 Jose scale in Arkansas was published during the year. The en- 

 tomologist acted as state inspector, the expenses being paid by the 

 iiui'serymen. 



The veterinarian of the station devoted much of his time to co- 

 operation with the Bureau of Animal Industry in the eradication 

 of the cattle tick and in examining diseases about the State. 



In animal husbandry the department of pathology and bacteriology 

 continued the experiments with wide and narrow rations for pigs, 

 and found that better results than from the exclusive use of corn
