The key that unlocks the door to
it is dynamite. An explosion,
breaks up the hard-pan, loosens
the soil far below the possibility
of any plow or cultivator to dis
turb it, and opens to the plant
the 8 tore of food that it needs.
Says Xeno W. Putnam, in article
on "Farming with Dynamite,"
contributed to Cassier's Monthly
(New York, August):
"Between the available farm
ing soil above and the underlying
mineral wealth below there is as
definite a boundary wall against
the intrusion of root growth as
there is against the farmer's cat
tle in the wire fence which shuts
them from the land of his neigh
bors.
"How to tap these rich miner
al veins has been the problem,
If the crust is not too hard cer
tain plants solve it for them
selves, though only in part
for their weaker neighbors.
