While the amount of added water had not been enough to cause 
it to seep from the bottom of the cylinder, it was enough to have 
supersaturated the soil if it had been under field conditions. The 
moisture relations are shown in figure 7. 
RED FIFE WHEAT. 
The seed used was from one of the plants grown on semiarid 
soil in the experiment of 1909. Ten seeds were planted in each 
of the 6 cylinders on February 5 ; 23 days later, when the plants 
were from 4 to 12 inches high, they were thinned to the most 
vigorous 1 in each cylinder. No further thinning was practiced, 
except in the case of VI. from which 3 plants were removed on 
April 27. The thinnings were dried and the weights included in 
those of the total dry matter reported in Table 11. Little differ- 
ence between the plants in the six cylinders was observed until 
the end of the first month. 
A summary of the data of the experiment is given in Table 
12 and the moisture conditions in the soil at the death of the 
plants are shown in Table 11 and in figures 7 to 11. Figure 12 
shows the condition of the plants on April 23 and on June 8 re- 
spectively. The roots separated from the different foot sections 
of the subsoil are shown in figure 13.
