botanical department continued the studies on cotton anthracnose 

 and the investigations on Mendelian and De Vriesian laws in appli- 

 cation to the cotton plant. Attention was mainly given to determin- 

 ing how the organism causing anthracnose lives over winter, and to 

 the growing of cotton ])lants for the selection and breeding of re- 

 sistant strains or varieties. The particular features to which 

 resistance may be due were also studied. 



The bacteriological department took up the stud}^ of the effect of 

 stable manure on the bacterial flora of soils. The number of bacteria 

 in treated and untreated soils was determined, the changes in the 

 predominance of species noted, and the ability of the treated and 

 untreated soils to nitrify cotton-seed meal and sulphate of ammonia 

 was compared. 



Work on the Texas fever project was begun in December. The 

 coMS under observation had had Texas fever and the work Avas under- 

 taken merely to determine the effect of the ticks on the blood and the 

 general condition of the animal due to their presence. 



The horticulturist took up the project on the application of Men- 

 del's law in hybridizing black and white varieties of Muscadine grape. 

 The work on the wilt of the Japanese plum, which was under way, 

 W'as again taken up. 



The inquiry into a new feeding standard for cattle by means of the 

 nitrogen balance was repeated with eight calves. This work consisted 

 of frequent digestion experiments and of tests of the metabolized 

 nitrogen. 



Under the Hatch fund, the animal husbandman conducted feeding 

 experiments with milch cows for the purpose of comparing a ration 

 made up of cotton-seed meal, cotton-seed hulls, and oat straw with 

 one consisting of corn silage, cotton-seed meal, and oat straw. The 

 results of this test were not very decisive, but taking into consider- 

 ation the cost of the rations and the health of the cows, the use of 

 silage was found preferable. A test w^as also made of silage as a 

 summer feed, and a comparison of rations with and Avithout corn 

 meal. At the present high prices, corn meal was not found to be an 

 economical suninier feed. In a feeding experiment with hogs, special 

 attention was given to testing the value of S03' beans in the ration. 



The dairy department studied the conditions required for making 

 fermented beverages with starters furnished by the manufacturers. 

 A studv of buttermilk showed that the buttermilk made bv churning 

 whole milk contained nnich more fat than that obtained from churn- 

 ing cream. It was concluded that this difference accounted for the 

 difference in palatability. 



The horticultural department recorded the time of blossoming of 

 eighty or more varieties of peaches and also made records of various 

 other kinds of fruit. Culture, fertilizer, and variety tests were con-
