barrel of molasses was carefully sampled, dry matter determined, 

 and the several samples mixed and analyzed. Samples of hay were 

 taken at the beginning, middle and end of each half of the period, 

 run through a cutter, dry matter determined, and the several samples 

 composited and further examined. Sutificient of each kind of feed 

 was procured to last during the entire experiment. 



Weighing the Animals. Each cow was weighed for three consecu- 

 tive days at the beginning and end of each half of the experiment, 

 the weighing being done in the afternoon before feeding and watering. 



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

 daily for seven consecutive days in each week, and preserved with 

 formalin in glass stoppered bottles. The method of sampling con- 

 sisted in slowly mixing the entire quantity of freshly drawn milk with 

 a disk mixer and immediately removing a small dipper fuir\ 



AVERAGE RATION CONSUMED BY EACH COW DAILY (Pounds). 



The basal rations were alike in each half of the trial, excepting that 

 two cows ate slightly less hay while receiving the corn meal ration. All 

 of the cows received daily four pounds of molasses, excepting Saman- 

 tha, which received three pounds. 



AVERAGE DRY AND DIGESTIHLE ORGANIC NUTRIENTS CONSUMED DAILY 

 BY EACH COW^'^ (Pounds). 



'5 In several instances because of an imperfect mixing of the daily additions the compos- 

 ite became clotted or lumpy after a few days. It was necessary, therefore, to discard these 

 few samples and to take others, so that in a few cases the samples only represented the milk- 

 ings of three or four days in each week.
