122 IMPORTANT TIMBER TREES 



the chances of the tree's living will be greatly lessened. It 

 is a well-known fact that when in close contact with the 

 soil roots of trees may be frozen very hard without injury 

 if their relative positions are not changed until both are 

 thawed out. But it is at all times necessary to protect roots 

 from injury which will come to them when naked and ex- 

 posed to the frost. In spring planting this danger is mainly 

 avoided, and can be entirely so if care is taken to protect 

 the roots from frost when the trees are removed from the 

 nursery to the forest, as it is seldom or never that the 

 ground freezes deep enough after spring planting has taken 

 place to injure the roots, if vacant spaces have been care- 

 lessly left, a condition which should not be tolerated. All 

 in all, spring planting is preferable, but conditions may 

 make it necessary to plant in the fall and run the risk of 

 success. 



It is claimed that coniferous evergreens, such as the 

 Pines and Spruces, can be safely transplanted in the latter 

 part of August. That will depend entirely upon the con- 

 dition of the year's growth. If the growth is completed, 

 then the removal at that time can safely take place. In 

 that case the roots will have an opportunity to do some- 

 thing towards repairing damages done them, but unless 

 the growth has practically ceased success cannot follow 

 that procedure.
