provements, but, unless the dairyman is willing to do his part and is 

 fully interested and anxious to co-operate in the work, nothing of 

 value will be accomplished. 



If the dairyman is willing to do the extra work necessary to obtain 

 sufficient information relative to the herd to enable the demonstrator 

 to assist him, the work will be taken up in earnest and systematically 

 conducted. 



The work already done shows that in practically every herd there 

 are many unprofitable cows, which largely consume the profits from 

 the good ones. To find out which cows are unprofitable it is necessary 

 to weigh the milk, test it and ascertain the amount of butter fat it con- 

 tains, and weigh the feeds. When this is done for a few months, the 

 data are obtained necessary to enable the dairyman to weed out his 

 unprofitable cows. 



To help the dairyman to obtain this necessary information, scales 

 for weighing the milk are loaned him and blank milk-record sheets 

 furnished. The time required to weigh the milk at each milking 

 from each cow during an entire year would not equal the loss from 

 feeding one unprofitable cow for that length of time. The feed should 

 be weighed three or four times a month and all changes noted and 

 record made of the same. 



At first the samples of milk for testing for butter fat are taken by 

 the demonstrator and the test made by him. The next and subsequent 

 months the dairyman will take the milk samples for two days imme- 

 diately preceding the regular monthly visits of the demonstrator, who 

 will make the tests for butter fat. 



The dairyman must keep these necessary records and is expected to 

 assist in calculating the results. 



In the handling of the dairy products the expert will give all the 

 assistance possible, with a view of enabling the dairyman to put upon 

 the market a first-class product. 



BUILDING OF. SILOS. 



In feeding, the advice and assistance of the demonstrator is fre- 

 quently of great value. As a rule, our dairymen do not produce their 

 own feed to the extent they should, nor do they give sufficient care to 

 the character of the feeds to obtain the best results. Silos are too rare, 

 and yet succulence is essential in dairy feeding. All dairymen are 

 advised to use silos, and those who wish to build them are assisted to 

 do so. 



The most desirable kind of silo for the conditions existing on "the 

 farm is determined, and plans and specifications furnished free of 

 charge. When the materials are on the ground, the demonstrator will 

 supervise the erection of the silo, and later will direct the filling of it, 

 in order that the dairyman may run no risk from lack of experience 

 in such matters.
