sprouts. In general, it is best not to mix trees with crops 

 or with the pasture, except as a few trees may be desired 

 as shade for stock, or as a windbreak. 



212. What Trees to Plant. The following are some of 

 the desirable trees for posts: Hardy catalpa (Catalpc 

 speciosa) makes one of the best fence-posts and grows 

 very rapidly on good land. It is adapted to rich, deep 

 soils south of the 41st parallel. Black locust makes a 

 very desirable tree where it is not ruined by borers. 

 Chestnut is one of the fastest-growing, good post trees 



for northeastern United 

 States. Osage orange is 

 probably the best post 

 material. It is a slow- 

 growing, drought-resist- 

 ant tree, adapted to 

 regions south of the 

 41st parallel. 



Some of the trees 

 adapted to the semi- 

 arid regions are bur oak, hackberry, black locust, white 

 elm, Russian mulberry, osage orange, red cedar, western 

 yellow pine, Jack pine. 



White pine, Norway spruce, chestnut, are among the 

 best trees for planting in regions where the white pine 

 once grew. For other regions and the numerous other 

 trees and combinations of trees, see Bureau of Forestry 

 Circular No. 30. 



Several states are growing young forest trees and furnish- 

 ing them at cost so as to encourage planting. Forest lands 

 should not be taxed in the same manner as farm land.
