___ Figure 6 gives in diagrammatic form the information contained in 
Table 7. A glance at the figure indicates a much more uniform 
moisture distribution in the horizontal columns than in the vertical 
columns. While it appears in the figure that the maximum percentage 
_ of moisture is not found exactly at the water end of the tube, yet the

Fic. 6.—Distribution of moisture in horizontal columns. 
Maximum percentage of moisture found in the tube is not much 
q pie than the percentage found in the first inch. The apex in the 
horizontal tubes is not so pronounced as in the vertical tubes. The 
_ striking feature of the curves is the relatively long stretch of the 
column containing approximately the same percentage of moisture. 
It will be noticed that in tube No. 18, filled with the Riverside soil, 
the moisture content at the extreme right end is greater than at the
