Most important, however, are the temperamental differences in men
which make some desirous of giving themselves to the cultivation of
a small area of irrigated land under intensive conditions and others
to dry-farming under extensive conditions. In fact, it is being
observed in the arid region that men, because of their temperamental
differences, are gradually separating into the two classes of
irrigation-farmers and dry-farmers. The dry-farms of necessity cover
much larger areas than the irrigated farms. The land is cheaper and
the crops are smaller. The methods to be applied are those of
extensive farming. The profits on the investment also appear to be
somewhat larger. The very necessity of pitting intellect against the
fierceness of the drouth appears to have attracted many-men to the
dry-farms. Gradually the certainty of producing crops on dry-farms
from season to season is becoming established, and the essential
difference between the two kinds of farming in the arid districts
will then he the difference between intensive and extensive methods
of culture. Men will be attracted to one or other of these systems
of agriculture according to their personal inclinations.
