THE DOUGLAS FIR loi 



of the Oregon, that exceeds in value, because of its 

 greater durability than that of the red wider-ringed 

 wood of the Colorado variety. 



In the contest for hardihood, the decision in favour 

 goes to the more slow-growing later immigrant to 

 Colorado. A want of robustness, however, can hardly 

 be urged against either, though it is true that the 

 quicker-growing Oregon, as he thrusts his head above 

 his lag-behind contemporaries, is oft in need of shelter 

 to ensure the safety of his topmost branches. It is 

 well, then, in prospecting for them their position in a 

 plantation, to look out for declivities sheltered from 

 prevailing winds. They both seem to show preference 

 for a northern and perhaps a western aspect, and bear 

 the reputation, in their younger stages of existence, 

 of being moderately tolerant of shade. It is estimated 

 that they may be expected to attain a goodly old age, 

 computed in America at from 400 to 500 years, but 

 reckoned, according to Veitch in his Manual of 

 Conifers, as from 450 to 750.
