Part I. — Outline of Year's Work. 



J. B. LINDSEY. 



A. Correspondence. 

 The general correspondence of this division has increased 

 considerably during the last five years, due especially to 

 the establishment of the feed control, and to the work in 

 connection with the dairy law. More than the usual number 

 of inquiries have been received relative to milk, cream, 

 water, feed stuffs and methods of feeding. Some letters 

 can be answered very quickly, while others require time 

 and study. The total number of letters written during the 

 year ending December 15 has been 2,186. 



B. Extent of Chemical Work. 



In the last report attention was called to the fact that the 

 ever-increasing demand on the chemists' time for work of a 

 routine character — the analyses of water, milk, cream and 

 feed stuffs — very seriously interfered with the extent of 

 experimental work. This has been particularly the case 

 the past year, due largely to the amount of time required 

 in connection with the dairy law. In fact, the work of 

 investigation has been seriously curtailed, which is much to 

 be regretted. 



There have been sent in for examination 242 samples of 

 water, 164 of milk, 1,557 of cream, 15 of pure and process 

 butter, 48 of oleomargarine, 106 of feed stuffs and 5 of 

 miscellaneous substances. In connection with experiments 

 by this and other divisions of the station, there have been 

 analyzed, in whole or in part, 148 samples of milk and 

 cream, 80 of butter fat and 563 of fodders and feed stuffs.
