Notice composition of the 60 pounds of timothy grass that a cow 

 would eat in a day. It contains 23.7 pounds dry matter, 1.68 pounds pro- 

 tein, 7.38 carbohydrates, 36 pounds fat, making a balanced ration of about 

 1 part protein to 5 of carbohydrates and fat, showing 30,554 heat units. 

 Cure the 60 pounds of grass into hay and we have about 20 pounds, all a 

 cow would eat on an average for five months, containing 17 qounds dry 

 matter instead of 23 in the grass, .57 pounds protein instead of 1.68; .24
