 haj, for grazing and soiling, and for soil improvement. A study of 

 the results in the summary table reveals, among others, the following 

 interesting facts: 



Peas. — The yield of peas in the varieties included in the tests for 

 four or more years range from 13.5 to 6.6 bushels per acre, the 

 varieties, in the order of productiveness, being:

 number of peas to plant to the acre, but should be, not so many peas 

 of the small and medium sizes being necessary as of the large ones 

 for the same area. 



Hay. — The yield of hay in pounds per acre of the several varieties 

 included in the test for four years and over vary from 3,872 pound? 

 to 2,400 pounds, the rank in order of productiveness for hay beintr
