Relation of ^Sonavailable Water to Hygroscopic Coefficient 103 
In the H O cylinder, which carried four plants from the first 
planting, the first ripened on April 29, producing 10 beans. Two 
other plants died during the next few days without having set 
any seed, and the last plant was dead by May 1. having pro- 
duced 7 beans. The cylinder was opened on the next day. Roots 
were abundant thruout the subsoil and the free water in the sub- 
soil was quite uniformly reduced to 1.6 to 1.9 per cent, it being 
slightly lowest in the sixth foot where fine roots were most 
numerous. The moisture content of the subsoil was 1.0 to 0.7 
per cent below the wilting coefficient. 
In the Wauneta cylinder, in which there were three early 
plants, the first was dead by May 15, producing 6 beans. The 
second plant was still in healthy condition as late as May 30 but 
was dead by June 6. From the third plant 3 ripe pods containing 
11 beans were removed on May 18. It continued alive and 
blossomed again before the end of the month. As late as June 
6 it was in fair condition, but was found wilted early on the 
morning of June 7. The next day it appeared quite dead and 
was removed, but the cylinder was not opened until 15 days 
later. While some water may have been lost from the surface 
foot by direct evaporation during these 15 days, it is highly im- 
probable that there was any important movement of water in 
the subsoil during the interval which elapsed between the harvest- 
ing of the last of the crop and the opening of the cylinder. 1 
Roots extended to the bottom of the cylinder but were not numer- 
ous in the sixth foot. The free water in the subsoil had been re- 
duced quite uniformly to 2 to 3 per cent to a depth of 54 
inches ; below this it rose gradually to 6.2 per cent. To a depth 
of 54 inches the moisture had been reduced from 2.0 to 3.0 per 
cent below the wilting coefficient but in the sixth foot it was 
about 2.0 per cent above the wilting coefficient. 
In the McCook cylinder, in which there were three late plants, 
one on June 6 ripened a pod containing 2 beans. This plant, 
however, as well as the two others continued green but made 
no growth. By July 18 all had died without forming any more 
seed. The cylinder was opened that day. Roots extended to the 
bottom of the cylinder and were abundant thruout the first five 
feet. The free moisture in the upper four feet of subsoil had 
been quite uniformly reduced to 1.0 to 2.0 per cent. In the sixth 
foot there was still 3.4 per cent. 
In the Holdrege cylinder the single surviving plant, from the 
first planting, ripened on May 18. producing 9 beans in two 
pods. Roots extended to the upper portion of the sixth foot but 
they had drawn very lightly on the moisture in the subsoil below 
the third foot, there being from 14 to 20 per cent of free water
