tons per acre, to the depth of four feet, 
in favor of the plowed land, which is 
equivalent to 1.45 inches of rainfall. If 
we consider for a moment what it would 
mean to have missed 1.45 of the 1.86 
inches of rain that fell during this period, 
The low moisture content in Grove A 
at Lake Weir may possibly be explained 
by the fact that here the roots of the 
trees are unusually near the surface of 
the ground, and as a consequence cultiva¬ 
tion has been shallow; and by the further

we may have a better conception of the 
importance of conserving soil moisture by 
means of cultivation.

fact that for several years past the grove 
has received practically no nitrogenous 
fertilizers, with the result that the soil is 
very much depleted of its store of humus, 
which, as has been pointed out, is a val¬ 
uable ally in the work of conserving soil 
moisture.
