It may be said in general that 100 pounds of hay from leguminous 

 crops contains about twice as much protein as 100 pounds of hay from 

 grasses. The leguminous hay may be safely estimated as worth from 

 one fourth to one third more for feeding than common hay. This is 

 true in spite of the fact that it d es not usually command a higher 

 price in the markets, owing to certain prejudices against its use. 



Assuming that the common grasses yield 2 tons of hay to the acre, 

 and clovers, etc., 3 tons of hay, the amounts of food materials and fer- 

 tilising materials in the crops are approximately as follows : 



Relative yield of food and fen'tilising materials in crops of hay from grasses and from 



leguminous crops.

The amount of hay produced on different farms varies so widely that 

 it is difficult to strike an average, especially for the leguminous crops. 

 It will be seen that on the above basis, which is believed to be a fair 

 one, the leguminous crops furnish from two to four times as much pro- 

 tein per acre as common grasses, together with much more fat and
