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, Wiekson* 

 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 iuclosure. 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.
