220 FOREST PLANTING. 



and, therefore, is especially qualified to form the stock 

 of trees in the higher regions. 



Should it be practicable to successfully grow the 

 larch, then the wild or dwarf mountain pine {pinus 

 pumilio) may be used as a covering and protection to 

 the former, during the first period of its growth. 



In the very highest regions, there does not exist any 

 forest vegetation except the wild or dwarf mountain 

 pine ; to try other trees is sheer waste of time and 

 money. 



Finally it should always be borne in mind that in 

 undertaking to replant such exj^osed localities, the 

 operation never should be begun at a place which is 

 from all sides exposed to the inclemencies of the 

 weather and situation ; but work must, if practicable, 

 be commenced at a place which adjoins an existing 

 stock or clump of trees or has any other protection, 

 and, shielded in this manner, planting should gradu- 

 ally go on till the whole area is set out. 



The seedlings to be employed in bleak and exposed 

 situations should be brought up as hardy as possible, 

 and so that they take girth in proportion to their height 

 and develop such a strong root system as to hold them 

 firm against violent winds. For this reason, when large 

 tracts in those locations are to be reforested, there 

 should be established in the midst of the grounds a 

 nursery for raising the required seedlings because plaiits 

 grown under less trying circumstances would not 

 thrive here. Certainly the nursery must be sheltered 

 against severe winds by building substantial stone 

 walls or earth embankments around them. These 

 dams should not be higher than about six feet, but 

 they should be covered with a strong and projecting 

 coping by which the wind is broken when it rises at the 

 wall. If the seedlings in exposed localities are too
