milo increased over one per cent. These results seem to indicate that 
the absorption of water by the milo from the soil and its translocation to 
leaves, was proceeding more rapidly in proportion to the loss of water 
from the plant than in the case of either corn or kafir. The fact that 
the leaves of milo seldom wilted during the day also indicated that fact. 
The wilting of the leaves of milo in contrast to either the corn or kafir 
usually could not be observed until much later in the day. The increase 
in the rate of loss of leaf water in the milo from 1 p.m. to 3 p.m. would 
indicate, that the rate of absorption of water from the soil during that 
period, was less than the loss by evaporation from the leaves. 
The amount of dry matter in the leaves of milo was at all times greater 
than in the leaves of corn or kafir of the same age. Taking the average 
weight of a square meter of corn leaf as 1, the average weight of an 
equal area of leaf would be 1.08 for kafir and 1.16 for milo. These dif- 
ferences in weight could be due either to the more compact arrangement
