when the trees are to be planted on dry or exposed situations where 

 conditions are r-^t the best for growth. The transplanting operation 

 stimulates the development of a more compact mass of roots of shorter 

 length, thus making the trees more easily handled. Transplanted trees 

 generally establish themselves more quickly than seedlings. 



The .age and size of trees most suitable for planting differs with the 

 species, the soil and moisture conditions of the land to be planted, and 

 also depends on the purpose of the planting. In general, small trees, 

 (i. e., 6 to 8 inches high) should be used. Small stock is less costly, is 

 cheaper to plant, and generally gives better results. When only a few 

 trees are to be planted, as for ornamental purposes, it is sometimes de- 

 sirable to use stock which is from 18 inches to 3 feet in height, although 

 trees of this size may be relatively expensive. If an evergreen wind- 

 break, shelterbelt or woodlot of considerable extent is to be planted, 

 it is generally preferable to use small, thrifty, transplanted trees, not 

 only because of the smaller cost of the trees themselves, but also be- 

 cause they can be planted more economically.
