i8 Report of the President. 



with seventy-four in 1904-5. Ninety-one students were registered 

 in the Winter Dairy course (State Extension work). The class 

 was unusually regular in attendance and attentive to work. The 

 demand for the men who have taken this winter dairy course 

 exceeds the supply. Correspondence amounting to over 5,000 

 letters was conducted by this department in 1905-1906. Seventy- 

 five visits have been made by Mr. Hall and his assistants to establish- 

 ments where former students are employed. Investigation has 

 been hampered by the unsettled conditions before mentioned but a 

 study of the bacteria of freshly drawn milk has been begun. 



V. The department of Rural Art has been in existence since 

 1 904-1 905 only. Its second year has been encouraging. The num- 

 ber of courses offered has been increased from one to four. The 

 courses now being given are Theory and Aesthetics of Landscape 

 Design, Work with Plans and Drafting, Plant Materials for Land- 

 scape Effect, and Advanced Work in General Landscape Design. 



VI. The department of Entomology has published two bulletins 

 in the Federal Experiment Station work. Bulletin No. 233 dealt 

 with saw-fly miners on European elms and alders. Bulletin No. 

 234 discussed the bronze birch borer. 



The Extension Work with State funds has been carried on under 

 three divisions. (a) The regular teaching work consisted of a 

 course on injurious insects given to thirty-eight students in the 

 short winter course in agriculture. (b) The experimental work 

 resulted in the issuance of Bulletin No. 235 on Co-operative Spray- 

 ing experiments. (c) The co-operative experiments have dealt 

 largely with insecticides and their effectiveness in killing the plum 

 curculio, rose-chafer and San Jose scale. The experiments prove 

 that these pests can be controlled by proper spraying. 



VII. The work of the Federal Division of the department of 

 Agricultural Chemistry has consisted of analyses of green corn 

 (30 samples), of root crops (182 samples), of soil (48 samples) 

 and of soil solutions (96 samples). The Extension Work has been 

 carried on chiefly in connection with analyses at the request of 

 farmers, the principal subjects of analysis being insecticides and 

 fertilizers. This department is now attempting to solve the prob- 

 lems relating to soil fertility on the Mitchell farm. 



VIII. A final and summary report is submitted by the depart- 

 ment of Botany in the Federal Experiment Station. The adoption 

 of the policy of separating the work of the Experiment Station from 

 that of teaching and research will necessarily make this the final
