The chief difference among varieties as shown in the 

 above table is in the percentage of pods and blooms. 

 Naturally this was greatest in the ^Vhippoorwill. for 

 this was the earliest variety, and when cut September 

 12 it had more large pods than did any other. This 

 earlier maturity also makes the Wliippoorwill show the 

 highest percentage of its weight available for animal 

 food, viz. : 75.4 per cent. On the other extreme is Clay, 

 which, Avhen cut at this stage of immaturity, (only about 

 2 per cent, of pods having colored), had only about half 

 the weight of the plant available for hay. 



Taking the average of all varieties, 03.6 per cent, of 

 the air-dry weight of the plant was contained in the 

 hav. 



The leaves, the most valuable portion perhaps except 

 the x>o<is, constituted 19 per cent, of the weight of the 

 entire plant, or 30 per cent, of the weight of the hay. 



Of tlie hay cut at a stage when on some varieties 

 from 2 to 10 per cent, of the pods had colored, and Avhen
