field remains very irregular in productiveness. There has been marked 
improvement in some spots, but in others the soil is still difficult to work 
into good tilth and takes water very slowly. 
In the early part of August, 1922, two series of wells were put down in 
this field. One line ran across the north side of the field and the other 
along the south side. The wells were set in the borders between the plats. 
Thejwells ofjthe south line were set about 15 feet in from the tile drain.

Fig. io. —Results erf experiments on the Newlands Experiment Farm with wells 8s feet apart in the 
borders between the plats. 
These wells permitted observations to be made from time to time as to 
the height of the ground water, and samples of this water could also be 
taken. The results of the first set of observations, made on August 5, 
1922, are shown in the upper diagram of figure 10 for the north line 
of wells and in the same position of figure 11 for the south line. These 
diagrams show the height of the ground water in relation to the ground
