THE DOUGLAS FIR tor 
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.
