reported. On account of the manner in which the Holstein tests 

 are conducted it is particularly difficult to obtain men always 

 when wanted. 



During the early part of the year the work was somewhat 

 handicapped, owing to the presence of foot and mouth disease 

 in the State. We were fortunate, however, in not having a 

 single case on farms visited by our supervisors. 



{e) Miscellaneous Work. 

 This section also does considerable chemical work in connec- 

 tion with experiments in animal nutrition. A number of samples 

 of milk have been analyzed for the Dairy Department in con- 

 nection with dairy shows and milk contests. For the station 

 apiarist it has determined the residual beeswax in a large num- 

 ber of samples of slum gum in order to enable him to ascertain 

 the efficiency of different methods for the extraction of beeswax 

 from honeycomb. 



4. Numerical Summary of Laboratory Work, December, 

 1914, TO December, 1915. 



There have been received and tested 90 samples of water, 516 

 milk, 1,315 cream, 1 ice cream, 229 feedstuff s, 178 fertilizer, 332 

 soil, 27 lime products, 49 slum gum, 17 samples bees for 

 arsenic, 6 arsenate of lead, 3 vinegar, 58 coal and 21+ miscel- 

 laneous. 



The fertilizer control work involved the collection of 1,322 

 and the feed control 1,043 samples. There have also been ex- 

 amined in connection with experiments made by the different 

 departments of the station 209 milks, 132 cattle feeds, 43 fer- 

 tilizers, 528 millet straw and seed, 255 oat hays, 88 rape plants, 

 4 soy bean hays, 1 alfalfa and 1 buckwheat hay. The above 

 totals 6,468 samples, and does not include the work of the 

 research section nor the work under the dairy law.
