HATCH EXPERIMENT STATION. 



[Jan. 



that cows 4 and 5 were receiving Atlas meal. In Period II. 

 this order was reversed. The cows were kept in the barn 

 during the entire experiment, and were treated precisely 

 alike during both periods. Two composite samples (three 

 days each) of milk were tested during each period. The 

 tables following give the average results from the four 

 cows : — 



Table I. 



Table II. — Average Yield and Cost of Milk and Butter Fat. 



Table III. — Average Composition of Milk. 



Results. 

 The cost and quantity of milk and butter fat are so nearly 

 equal in each case as to be considered practically identical. 

 If the quality of the Atlas meal is maintained, it can be 

 resrarded as an excellent food for milch cows and neat stock 

 in general.
