SANTA CLARA AND CACHE VALLEY SOILS. 
The fourth set of experiments consisted of three tubes filled with 
soil from Santa Clara County, Calif., and one tube filled with medium 
loam from Cache Valley, Utah. The Santa Clara soil is very similar 
in its capillary behavior to the Whittier soil. The Cache Valley soil 
is typical of the bench loam soils of the Intermountain States. 
Tube No. 13 filled with Santa Clara soil was packed in 2-inch 
layers and made firm by raising from the floor and dropping in a 
manner similar to the packing of tube No. 1. After packing and 
before placing in position, the tube was inverted so that the end filled 
last was at the bottom when placed in water. This tube was allowed 
to stand 13 days and then was sampled immediately. 
Tube No. 14, filled with Santa Clara soil, was packed by the same 
method as tube No. 13. The joints of the 1-inch sections were open 
and not sealed with friction tape. This tube stood in position 15 
days and was then sampled immediately. 
Tube No. 15 was filled with Santa Clara soil and packed in the 
same way as tubes Nos. 13 and 14. This tube was also inverted, 
allowed to stand in position 18 days and then sampled immediately. 
Tube No. 16 was filled with Cache Valley soil packed in the same 
way as tube No. 14. This tube was allowed to stand in position 24 
days, and was then sampled immediately. 
Table 6, arranged in the same manner as the preceding tables, 
ives the moisture distribution at the end of the tests of the last 
our tubes.
