It was soon found that an intermittent flow of such a small quantity 
of water was not sufficient to irrigate economically even the small demon¬ 
stration plots of the Experiment Station; and, as no other provision was 
made for disposing of the discharge, very little pumping was done dur¬ 
ing the year. Observations were continued with reasonable regularity 
on the various test wells, the profiles of which are shown in figures 2 to 
7. The pump was in operation for so short a time and the amount of 
water pumped was so small that there was no appreciable effect on the 
ground-water table, even in the immediate neighborhood of the pump.
