This report is intended to give aji ontline of the work ac- 

 complished and in progress in the department of })hint and 

 animal chemistry for the year 1910. 



1. Correspondence. 

 There have been substantially 5,000 letters sent out during 

 the year ending Dec. 1, 1910, the estimate being made on the 

 basis of stamps used. The correspondence divides itself into 

 (a) answering letters of inquiry, (6) the execution of the fer-

2. Numerical Summary of Work in the Chemical Lab- 

 oratory. 



From Dec. 1, 1909, to Dec. 1, 1910, there have been received 

 and examined 101 samples of water, 459 of milk, 2,799 of 

 cream, 151 of feed stuffs, 223 of fertilizers and fertilizer mate- 

 rials. 44 of soils and 48 miscellaneous. In connection Avith 

 experiments made by this and other departments of the station, 

 there have been examined 247 samples of milk^ 115 of cattle 

 feeds and 300 of agricultural plants. There have also been 

 collected and examined 890 samples of fertilizer, in accord-

 feed law. The total for the year has been 6,432. This sum-
