examined has been 104, whi(;h is eonsiderablj^ less tiian when 

 the work was done tree of oost. It is believed that this charofo 

 has held in check those who have heretofore abused the privi- 

 lege by sending in a large number of samples, in some cases 

 out of mere curiosity. 



Instructions for securing an analysis of water : — 



Those wishing to secure a sanitary analysis of water must first 

 make application, whereupon a glass bottle securely encased, 

 accompanied by full instructions for collecting and shipping 

 the sample, will be forwarded by express. The return express 

 must in all cases be prepaid. Because of the smallness of the 

 sum involved, no account will be opened. Remittance by 

 check, P. 0. money order, or money at the owner's risk, must 

 be strictly in advance. 



Address Dr. J. B. Lindsey, 



Hatch Experiment Station, Amherst, Mass. 



(b) Dairy Products and Cattle Feeds. 



The station received about the usual number of samples 

 of milk and cream. Many samples are sent by farmers to 

 ascertain the quality of milk produced by their herd or by 

 individual cows, and this should meet with every encoui-age- 

 ment. Printed circulars are sent in answer to inquiries, 

 giving concise information concerning the quality of milk 

 produced by different breeds, as well as full instructions 

 relative to the best methods of determining the productive 

 capacity of the dairy herd. The station also tests a large 

 number of samples of milk and cream for creameries at a 

 charge sufficient to cover the cost. 



About the usual number of feed stuffs were received dur- 

 ing the year. These come from practical feeders, who either 

 suspect adulteration, or desire to know the value of a feed 

 new to their locality. The results of the examination are 

 returned promptly, together with such information as is 

 suited to the })articular case. A considerable number of 

 samples are also received from feed dealers, who wish to 

 make sure as to the intrinsic value of the materials they are 

 offering. It is believed that this desire for information 

 should be encouraged as much as the limited resources of the 

 department pei-niit.
