THE SEASON. 



A comxiarison of the precipitation of the season of 1915 ^th that of the four 

 previous seasons might explain some of the discrepancies in yield. 



Precipitation, in inches. 



This table does not show the full effect of the low total precipitation because of 

 the wa.y it was distributed. There were only two showers that wet the ground to a 

 depth of 2 inches, and in most cases the showers were so distributed as to be dried off 

 in a few hours. Added to the low precipitation is the damage done by frost on June 

 7, 14, and 16, a temperature of 24-2 degrees being reached on the last date. This froze 

 all cereals to the ground. 



SPEIN'G WHEAT. 



FoUewing are the yields per acre for 1915 of the principal varieties of wheat, 

 together with the yields for each of the previous four years and the number of days 

 maturing in 1915. These grains were sown on April 21 on summer-fallow, and the 

 yields are computed from the weight of grain on one-fortieth of an acre: — 



The average yield of Mnrqui.q wheat on 8 acres of fallow in 1915 was 34 bushels, 

 11 pourwis, and on 6 acres of full ploughed wheat stubble was 17 bushels 19 pounds. 

 Two acres of Marquis wheat on fall-ploughed corn ground that had been fallowed and 

 manured preceding the com yielded at the rate of 39 bushels 52 pounds.
