Report of the President. xix 



(c) The extension work, following the hnes of previous years, 

 has consisted in an extensive correspondence regarding injurious in- 

 sects, a few co-operative experiments with farmers in spraying, and 

 attendance at fairs with exhibits of injurious insects. 



X. Department of Dairy Industry. 



(a) Thirteen regular courses were offered by this department 

 with a total registration of 378 students. Besides this, instruction 

 was given to 179 Winter Course students, making a total enroll- 

 ment in the department of 557. 



(b) The following are some of the lines along which experi- 

 mental work has been conducted. First, the cow testing begun 

 last year has been continued with results that will without doubt 

 prove of commercial value to diarymen. Secondly, supervision of 

 the milk supply for the city of Ithaca has been continued in co- 

 operation with the city board of health, and has resulted in im- 

 proving the general quality of the milk sold in the city. Thirdly, 

 an improved method has been worked out for determining the 

 percentage of moisture in butter. Fourthly, the study of bacteria 

 in drinks manufactured from fermented milk has been continued. 

 Fifthly, studies have been made to determine inexpensive methods 

 whereby the small milk producer may, under more sanitary condi- 

 tions, produce cleaner milk without materially increasing the cost. 



(c) Several thousand letters have been written in answer to 

 inquiries from dairymen all over the State, and exhibits and in- 

 struction have been given at fairs.
