dry matter at the end of each half of the trial, and eventually 

 completely analyzed. Sufficient of each of the several grains 

 was purchased at one time to last during the entire experiment. 



Sampling Milk. — The milk of each cow was sampled twice 

 daily for five consecutive days and preserved in glass-stoppered 

 bottles. The method of sampling consisted in mixing the freshly 

 drawn milk with an especially constructed mixer, and imme- 

 diately removing a small dij^perful. 



Character of the Feeds. — The hay and rowen were of excel- 

 lent quality. The former was a mixture of Kentucky blue grass 

 with some clover and the latter was largely grass rowen. The 

 quality of the bran was not particularly satisfactory. It was 

 bought by sample, and had the appearance of being a fairly 

 clean, winter wheat product. As the experiment progressed it 

 was found that some bags contained a considerable admixture 

 of middlings and some wheat hulls. Towards the latter part of 

 the second half of the trial the variation became so noticeable 

 that Washburn Crosby's spring bran was substituted for the 

 remainder of the experiment. The source and quality of the 

 alfalfa meal have already been mentioned. 



Effect of Alfalfa on General Condition. 

 The alfalfa meal was fed mixed with the other grains. The 

 animals ate the mixture readily and kept in uniformly good 

 health, as did those receiving the bran ration. The alfalfa 

 ration produced rather more of a laxative effect than did the 

 bran.
