The gist of the whole matter is to select those 
kinds of trees which are most thrifty and healthy 
in the particular locality, and which are least in- 
fested by fungi and insects that are also common 
to fruit plants, and then to study the local condi- 
tions carefully to determine how dense or how open 
the shelter should be. For California, Wickson* 
recommends species of eucalyptus, pepper or schinus, 
Monterey cypress, Monterey pine, osage orange, locust 
and maples. “Quite a number of the larger grow- 
ing deciduous fruit trees,” he continues, “are used 
to some extent along the exterior lines of orchards 
for the protection of the inclosure. The fig, the 
walnut, the chestnut, seedling almonds and apricots, 
are especially commended for such use.” 
In Florida it is a common practice to leave 
strips of the original forest to serve as_ shelter 
belts. If this forest is hammock land, and there- 
fore well clothed underneath, the protection of a 
belt two to four rods wide will be most complete.
