resinosa, namely, of 35 metres and more. As 

 the climatic conditions of the greater part of 

 Germany resemble each other more closely than 

 those of the United States where the banksiana 

 is found outside its natural home, that is, in 

 warmer latitudes, the prospects for the height 

 development of this species of pine in Germany 

 are far more favourable than have been hitherto 

 imagined. 



32. Pitms rigida. 



This three-needle sheathed pine is, generally 

 speaking, a rapid-growing, light-loving variety of 

 tree which, however, requires a warmer climate 

 (coast districts and the inland climate for oak 

 and sweet chestnut). Although, as a rule, its 

 demands with regard to quality of soil are quite 

 modest, it does not come up to indigenous pines, 

 not to speak of the banksiana, on the very poorest 

 lands. Its long stiff needles expose it to being 

 weighed down by snow, and in its younger 

 stages of growth it suffers very severely from 

 injury by snow. It is so liable to damage from 

 forest animals that it is hardly possible to 

 raise it without some kind of protection. The 

 damaged parts heal up rapidly, as it possesses 

 the peculiarity of being able to develop its 

 dormant buds, hence its reputed reproductive 

 capacity from the stool after being cut down
