128 EXPERIMENT STATION. [Jan. 



The Jersey, Guernsey and Ayrshire chibs are formulating 

 uniform rules for testing, and will probably, in the near future, 

 adopt a one-day monthly test instead of the two-day test now 

 in use. 



4. NuMEKiCAL Su]\;:mary of Substances examijSTed in the 

 Chemical Laboratory. 



The following substances have been received and examined: 

 110 samples of water, 372 of milk, 2,018 of cream, I-IG feed- 

 stuffs, 200 fertilizers and fertilizer refuse materials, 40 soils, 

 13 lime products, 8 ash analyses of plants and 2 miscellaneous. 

 There have also been examined in connection with experiments 

 in progress by the several departments of the station, IGO sam- 

 ples of milk and cream, 129 cattle feeds and 478 agricultural 

 plants. In connection with the control work there have been 

 collected 1,180 samples of fertilizer and 902 samples of feed- 

 stuifs. The total for the year was 6,859. 



The above does not include the work of the research section. 

 In addition, 28 candidates have passed the examination and se- 

 cured certificates to operate the Babcock test, and G,056 pieces 

 of Babcock glassware have been tested for accuracy, of which 

 only 27 i)ieces, or .45 of 1 per cent., were condemned as in- 

 accurate. 



5. Correspondence. 

 The number of letters sent during the year approximates 

 G,500, the data being based upon the number of stamped enve- 

 lopes used. In addition a large number of circular letters have 

 been mailed as an adjunct to our inspection work. The larger 

 part of the correspondence is devoted to work in connection with 

 the inspection of fertilizers, cattle feeds, dairy apparatus and 

 the testing of pure-bred cows. A considerable amount of time, 

 however, is still given to answering special inquiries made 

 by farmers and others relative to plant and animal feeding, and 

 the composition and value of fertilizers, cattle feeds and milk.
