meal fed to the Brown vSwiss herd contained 37.4 per cent albumenoids and 

 that fed the Jerseys 42.1 per cent, or a difference of 4.7. In other words, 

 on an average, one lot of cotton seed meal contained an eighth more al- 

 l",nmenoids than the other. On the other hand, we find that the Jersey 

 cotton seed meal contained only 25.3 per cent nitrogen free extract or 

 carbo-hydrates, while that fed the Brown Swiss ran to 29.75 P*^^ cent, 

 or a difference of 4.44 per cent or more than one-sixth more fat and 

 energy-forming food. A comparison of the corresponding figures for 

 the gluten feed shows that the gluten feed fed to Shorthorns contained 

 approximately one-fourth more of albumenoids and one-fifteenth less 

 nitrogen free extract than that fed to the Holstcins. It might be added, 

 however, that the former was also lower in ether extract or fat. We 

 shall call attention to one other such a difference. In the case of "corn 

 hearts," we find the most marked discrepancy, the per cent of albumenoids 

 in that fed to one herd being only half of that fed to the other two herds. 

 None of the feeds used contained any mysterious principle. They were 

 all common feeds, available to any feeder. We find that the bran used 

 was lower in feeding value than our standard figures, as reported by 

 the United States Department of Agriculture, and the ground oats did 

 not nearly come up to the average standard. If this is true of our two 

 commonest feeds when bought for demonstration purposes,. there is per- 

 haps much ground for the charge often made that dairy feeds often fall 

 below the standard in nutriment. 



At four o'clock milking began. In each barn there were from three 

 to five milkers. To aid in proper supervision, the cows were arranged 

 in a semi-circle about a central elevated ])latiorm from which a good 

 view of the barn could be obtained. Here the milk was received by one 

 of the "checkers" while the other saw that the milk buckets were empty 

 when a milker began to milk a cow, and that the milking was properly 

 done. When a milker had finished milking a cow, he brought the milk 

 on to the platform where it was poured into a sample bucket, which was 

 of uniform diameter, and weighed on a spring balance. After recording 

 the weight, a sample was taken ])y means of a "milk-thief" or tube of 

 uniform diameter. To secure enough milk to make a lactometer reading, 

 and at the same time avoid dip])ing mnvc tlian once, the ordinary com- 

 mercial "milk-thief" was discarded for one of greater diameter. The 

 uniform shape of the sample bucket and "milk-thief" insured an accurate 

 sample. Samples of morning, noon and evening milk from each cmv were 

 placed together in pint sample jars. Each jar was tagged with the barn 

 number of the cow. These jars were locked in a compartment case, and 

 pnce each day were sent to the laboratories to be tested. The samples
