Figure 25 gives the distribution, by 4-inch sections, in each of the 

 tubes. Here, as in the previous experiment, it is shown that the moisture

 content farthest, from the source of supply. 



This difference is not so great with the loam and the mixture of sand 

 and loom, but it is very marked in the clay, the clay plus sand, and the
