TIMBER. 



DOUGLAS FIR. The home-grown timber of this species is 

 apt to be somewhat coarse and knotty, owing to the retention of its 

 side branches even under a somewhat dense canopy. 



The annual increment of the timber is large, and, under proper 

 conditions, its value ought to exceed that of the Scotch pine. 



The timber may be used for all purposes to which that of 

 Scotch pine is applied, and as a somewhat inferior substitute for larch. 



SILVER FIR. The timber of this species is coarse and usually 

 full of knots. It is imported into this country under the name of 

 Swiss pine. 



■■ The reason for the presence of the same species in more than one class is 

 accounted for by the more or less favourable conditions under which they, grow, as, 

 for instance, in the case of Scotch pine, which may be present in all three classes.
