82 NEW HAMPSHIRE COLLE( i E 



sixty-seven samples of fertilizers were collected under the joint 

 supervision of the secretary and the chemist. These samples 

 represented one hundred and twelve distinct brands of fertilizers 

 and chemicals from twenty-four different manufacturers. It 

 was found necessary to employ extra assistance for the work 

 and Mr. F. D. Fuller and Mr. C. W. Vickery were engaged for 

 ten weeks. 



In connection with the feeding experiments, numerous analyses 

 of silage and of milk were made. The amount and nature of 

 the acid in the silage was also studied in continuation of a 

 series of experiments extending through several seasons. 

 Methods for determining potash in fertilizers and for analyzing 

 cattle foods were tested in cooperation with the Association of 

 Official Agricultural Chemists, upon samples furnished by its 

 reporters. 



The amount of miscellaneous work for the public was greater 

 this year than last, which was due to the increase in the number 

 of samples of water sent to the station. One hundred and 

 thirty-six miscellaneous samples were analyzed in all, eighty- 

 four of which were water and twenty-five milk, while the 

 remainder included soils, ashes, and other fertilizing materials, 

 dairy products, cattle foods, and insecticides. 



Two dairy tests were conducted by an assistant of this depart- 

 ment, one with a herd competing for the prize offered by the 

 Ayrshire Breeders' Association and the other with a single cow, 

 in cooperation with the Holstein-Friesian Association. The 

 results of these tests are published by the respective societies. 



The chemist has been ably assisted in all the work of this 



department by Mr. Charles D. Howard. The work of the other 



departments of the station is summarized in the following 



pages.
