seen that a much higher water content was maintained in the 
soils on the northeast slope. 
Fic. 14. Graphs showing the march of soil water to a depth of 5 feet 
on a northeast slope from April 18 to August 15, 1914, and the water con- 
tent of the soil on December 6, 1913. 
In order to further check these deep soil water conditions 
samples were again taken in duplicate on the northwest and south 
slopes of another prairie-covered hill. These findings, indicated 
in Table VI, check very closely with the preceding, and the strik- 
ing difference between soil water content on the two hillsides at 
all depths is well shown. 
It may also be noted that at each determination the soil at any 
depth was drier than at the same depth at the time of the preced- 
ing determination. On the south slope, it is interesting to note 
that without exception, the soil moisture increased with depth, and 
that the same condition maintains in most cases for north-side soils.
