In the experiment on barley, made in 1891, the amount of water consumed in 

 inches in depth on the ground area was found to be 13.19, while in the experiment of 

 1892, 23.52 inches were consumed. Oats in 1891 gave 19.69 inches and 19.0 inches 

 in 1892. Corn shows a large consumption in all the experiments, the quantity being 

 26.39 inches in 1891, and 25.09 inches in 1892. Clover in 1892 required a total 

 depth of water of 29.73 inches. Field peas required 16.89 inches in 1892. 



In the experiments on oats in 1891, the dry matter per acre amounted to 8,861 

 pounds, total depth of water being 19.69 inches. In 1892, with a total dry matter per 

 acre of 8,189 pounds, the total depth of water required was nineteen inches. In 1894 

 the yield of dry matter per acre was much larger than the previous years, ranging 

 from 10,350 pounds to 12,900 pounds, consumption of water ranging from 30.48 

 inches to 31.18 inches. The experiments on potatoes show ranges in dry matter 

 per acre from 8,248 pounds to 13,370 pounds, depth of water on the ground 

 area ranging from 21.31 inches to 27.06 inches. 



In regard to the consumption of water by potatoes, Mr. King remarks that what- 

 ever may be said regarding the yields of dry matter it is evident enough from the data 

 that potatoes used a very large amount of water and since the surface of the ground 

 was kept dry during the whole season, very much the larger proportion of the water 

 must have passed through the vines and only a small part of it could have been lost 

 through the soil directly. 



It is also pointed out that in regard to oats in all the experiments the total yield of 

 dry matter was much larger in 1894 than in the previous years, the amount of watei 

 used being also relatively higher; the experiments of 1891 and 1892, averaging 509.5
