rain did apparently but little injury to two of the varieties, but injured 
the third, especially those plots which had been treated with sodic 
nitrate, very badly. This rainy period was, of course, accompanied by 
niore or less cloudiness and dewy nights- I have given the number of 
cloudy days for the months concerned in 1913 and 1915. This simply 
gives a general and very indefinite measure of the sunshine. These 
tables, however, give the best meteorolgicab data that I have* ' 
The crops for the three seasons are given in the following tabular 
statement. The bushels are thresher weights; the weight per bushel 
is for cleaned wheat; and the ratio of straw to wheat is based uj>on the 
weights of straw and grain as threshed. ' ' '
