Character of the Feed Stufs. — The bran was from spring 

 wheat, the other grains were of the usual good quality. The 

 silage, made from rather poorly eared corn, was of average 

 (juality. The hay was largely Kentucky blue-grass, with 

 some clover. 



Weighing the Animah. — The animals were weighed on 

 three consecutive days at the beginning and end of the sec- 

 ond period. 



Sampling Feeds. — The coarse fodders were sampled three 

 times during the second period, dry matter determinations 

 made immediately, and composite samples analyzed. Small 

 samples of the grains were taken daily and placed in glass- 

 stoppered bottles. 



SamjMng Milk. — The milk of each cow was sampled 

 twice daily for five consecutive days of each week of the 

 two periods, and preserved with formaline in tightly corked 

 bottles. The method of sampling consisted in mixing the 

 freshly drawn milk with an especially constructed mixer, 

 and immediately removing a small dipper full. 



Average Ration consumed by Each Coiv Daily (^Pounds'). 

 First period : both herds, bran ration. 



Herd I. received practically the same quantity of grain 

 and roughage daily in each period ; the same can be said of 

 Herd II. Herd II. needed and received slightly more than 

 Herd T. during both periods.
