Four varieties were planted in the fall of 1912 and fourteen 

 varieties in the spring of 1913. See Table LUL Hard red winter, 

 semi-hard spring, and soft bread wheats, macaroni wheats, and one 

 plot of PoHsh wheat were included in the varieties. The best yield

Better returns were secured in 1915, a plot of Marquis yielding 

 1280 pounds of grain per acre. 



A summary of the variety test of wheat on the Prescott Dry- 

 farm is given in Table LIV. In this table annual yields of a given 

 variety represent the average of all plots of that variety in the 

 year named.
