duction of spruce, either pure or in a suitable mixture, 

 the yield at the end of fifty years would be in excess of 

 twenty thousand cords exclusive of thinnings. This invest- 

 ment would serve as timber insurance against accidents such 

 as fire, insect depredation, and other destructive agents, 

 in fact as a safe guard for the economic future of the 

 company. If the lands devoted to natural regeneration main- 

 tained their yield, which of course is highly probable, any 

 surplus cordage v*>uld be readily disposed of tit that time. 

 TO facilitate administration and management, concentration 

 of forest growth is only a question of time, if the histories 

 of European countries is to be taken as exemplary. 



Even when regeneration is natural, nursery 

 stock used to fill in the blanks in the reproduction would 

 shorten the rotation, and increase the yield by making all 

 the forest property productive. That is, whether ttie young 

 plants are being grown to establish artificial stands or 

 simply to fill in f ad 1 places in the natural reproduction is 

 immaterial; the greatest single factor in the success or 

 failure of a plantation is the production of the most suitable 

 plant possible for the purpose. 



The choice of species is restricted to some 

 tree of general adaptability to planting sites, and at the 

 same time yielding a product of the highest order. Thus, in
