This
surpasses the best harvest of alfalfa. Kearnley, who has made a
special study of dry-land olive culture in northern Africa, states
that in his belief a large variety of fruit trees may be found which
will do well under arid and semiarid conditions, and may even yield
more profit than the grains.
It is also said that many shade and ornamental and other useful
plants can be grown on dry-farms; as, for instance, locust, elm,
black walnut, silverpoplar, catalpa, live oak, black oak, yellow
pine, red spruce, Douglas fir, and cedar.
The secret of success in tree growing on dry-farms seems to lie,
first, in planting a few trees per acre,--the distance apart should
be twice the ordinary distance,--and, secondly, in applying
vigorously and unceasingly the established principles of soil
cultivation. In a soil stored deeply with moisture and properly
cultivated, most plants will grow. If the soil has not been
carefully fallowed before planting, it may be necessary to water the
young trees slightly during the first two seasons.
Small fruits have been tried on many farms with great success.
