REFORESTATION AND TREE-PLANTING. 157 



suited to exist in the particular section of country 

 that is to be reforested. 



Since those sections of country where reforesta- 

 tion is to be attempted have already, by the removal 

 of the forests, been exposed to the loss of soil, 

 great care must be taken in the replanting of trees 

 not to needlessly disturb the soil. Two methods 

 may be employed in reforestation, viz. : 



1. Sowing. 



2. Tree-planting. 



Considerable difference of opinion exists as to 

 which of these two methods is preferable. Un- 

 questionably, however, each is best suited for par- 

 ticular cases, and, in point of fact, each has been 

 adopted with considerable success in different parts 

 of the world. 



Seeding can, perhaps, be most profitably fol- 

 lowed in the temperate latitudes, in situations 

 where the growth of the tree is comparatively 

 certain. In higher latitudes the planting of trees 

 is, perhaps, preferable, since the germination and 

 continued growth of the seeds are by no means so 

 certain. 



In the case of the destruction of the forest by 

 avalanches, replanting or reforestation is rendered 

 much more difficult by the fact that the soil, in
