THE DOUGLAS FIR. 5 I 



about forty years old, so the two species should reach maturity 

 at the same time 



In conclusion, I may say that in my opinion, although 

 Douglas fir should be largely planted, those responsible for 

 the management of woods must not make the mistake that 

 was made with the European larch by planting it here, there, 

 and everywhere, without regard to its requirements as to soil 

 and situation, just because it is a profitable tree to grow. For, 

 if a disease entered, it would get a firmer hold of the trees 

 planted on unsuitable soil, and from these it would spread to 

 other plantations, as Peziza Willkonunii has done in the case 

 of larch. 



At present the greatest insect enemies of the Douglas fir 

 are the " Pine Weevil," which seems to prefer it to its " name 

 tree " the Scots pine, and Megastigmus Spermatroplius ; and it 

 is sometimes severely attacked by the fungus Botryiis Douglassii. 

 It is the duty of all those interested in forestry to do their 

 utmost to keep these evils in check. 



Pure planting is the best method of raising this tree, as there 

 is no species that will keep pace with it in height-growth so as 

 to suppress the side-branches, which we all know is necessary 

 to produce good timber. But yet, in the event of a disease 

 attacking the species, will not the same objection apply to the 

 pure planting of the Douglas fir as applies to the pure planting 

 of larch ? 



Lastly, if success is to be looked for with the Douglas fir the 

 ground-game must be kept well under, as rabbits and hares 

 will both attack it.
