Fig. 34. Roots of corn. 
The branching of the milo plants favored the exhaustion of 
the soil moisture by greatly reducing the transpiring surface 
after the root system had been fully developed and the moisture 
content much reduced. 
Little difference in the growth of plants and in the develop- 
ment of roots was observed between the most westerly loess soil — 
from Wauneta — and the neighboring residual High Plains soil 
from Madrid. 
Except in the case of those from the most easterly of the five
