Neither of these diagrams indicates that there is a definite relation between the yield of crop and the quantity of drainage water from any tank. Apparently the moisture supply was adequate to produce as large crops as the other factors would allow. This shows strikingly the possibilities of storing moisture in a well-drained clay loam soil, and raises the question whether, with a normal rainfall in this climate and ^ ^ 3900- >5 J800- I 3700- r^36O0- ^ 3500- \ J300-\ ^ 32C?0 < 3IOO- \X3000- \Z9O0- i Y/e/c/s of dri^ maffer.

A comparison of the yields of crops on the tanks in 1910, and for the same year on the corresponding field plats — which latter had no artificial drainage but received the same fertilization and produced the same kind of crops as the tanks — shows a much larger yield from the tanks. To what extent this is due to the thoro aeration to which the tank soils are subject, and how much is due to the moisture supply, it is impossible to say. The comparison is recorded in table 16: 35.
