For all these reasons the value of this timber 

 is of small account, at any rate in Germany, 

 even if, indeed, it possesses any at all. Its 

 cultivation inland can only be justified by the 

 expectation that the tree may, later on, be 

 grown for resin-tapping. 



23- Pinus strobus. 

 It is quite impossible, in this place, to do 

 justice to the enormously comprehensive litera- 

 ture on this subject by mere quotations from the 

 authors and reference to their observations. In 

 the following lines the idea is simply to give a 

 collective sketch of the sylvicultural peculiarities 

 of this highly interesting and valuable species of 

 timber tree. It is just the fundamental differ- 

 ence it displays as against the indigenous two- 

 needle sheathed pines that has assured it a 

 position among the forest trees worth planting. 

 Moreover, the other remaining species belong- 

 ing to the strobus division share, according to 

 Mayr's reports, the same sylvicultural pecu- 

 liarities. This is more especially the case as 

 regards the European strobus, the Greek Wey- 

 mouth pine, Pinus peuce, which possesses only 

 one disadvantage as against the American
