meal and old-process linseed meal ; and in case of the wide 

 ration, wheat l)ran and corn meal. In this experiment the 

 feeds were entirely consumed. 



The feeds were very carefully weighed out, and given twice 

 daily. Water was kept before the animals constantly, by 

 means of the Buckley self- watering device. A cover swung 

 upon hinges kept the feed from getting into the water. The 

 animals very soon learned to lift the cover whenever they 

 desired to drink. 



Sampling the Feeds. 



A small sample of the different grain feeds was taken daily, 

 and preserved in glass-stoppered bottles ; a sample of the 

 hay was taken weekly, and likewise preserv ed ; and at the 

 end of each of the two halves of each experiment dry-matter 

 determinations were made and samples preserved for analysis. 

 In case of the sugar beets and ensilage, samples were taken 

 weekly and tested for dry matter at once, and at the close of 

 the experiment these several samples were mixed and pre- 

 served for analysis. 



General Care. 



The cows were milked twice daily, about five o'clock in the 

 morning and live in the afternoon, always by the same at- 

 tendant, who was a graduate of the college, and thoroughly 

 trustworthy. The animals were carded daily, and allowed 

 the run of a yard in pleasant weather. They were given 

 plenty of stall room, and made as comfortable as possible. 

 The wing of the stable in w^hich they were confined contained 

 no storage room, and each animal was allowed fully 1,200 

 cubic feet of air. The wing was heated with hot water, and 

 kept at a temperature of 50 to 55 degrees F. during the 

 winter months. Ventilation w^as secured by means of a shaft 

 8 by 15 inches, placed at the south end of the wing, running 

 to within 1 foot of the floor, and extendinof 12 feet above the 

 roof, terminating in a so-called Archimedean ventilator. In 

 the shaft was placed a hot- water coil, to increase the draught. 

 Air was admitted by means of windows opening into the 

 barn, thus avoiding direct draughts. The windows were 

 suflScient in number to keep the barn fully lighted.
