In flume 90 the same conditions are found as in flume 31. except 
that during the month- of January and February there is an appar- 
ent discrepancy in the percentages of moisture in the bottom 5 inches 
d 1 the top o inches of soil. This apparent discrepancy is probably 
the i 3ul1 i temperatures below the freezing point and will be 
considered in a subsequent part of this report in connection with 
other similar analyses. 
All of the flumes -how a gradual decrease in the percentage of 
'-tiire from the tank end of the flume to the outward extremity 
i f the wetted area. In flume 20, the average percentage of moisture 
decreases at the rate of approximately 1.75 per cent for each linear 
the third and eleventh feet. In flume 50 the rate of 
decrease is about 2.2 per cent per linear foot. The rate of decrease 
varies in these flume-, as would be expected not only from the dif- 
ferent r orologi 1 condition- when the experiment- were run. but 
also from the character of the soil.
