NOTES ON THE DOUGLAS FIR. 1 5 



Canadian Douglas Fir^ by Stern — a work which gives the 

 results of tests carried out in the Forest Products Laboratories, 

 M'Gill University ; and Frohingham's The Douglas Fir, a U.S.A. 

 Forest Service Circular, which was published in 1909, and does 

 not take account of the results of recent work. 



The series of tables which are placed at the end of the paper 

 were compiled from data contained in T/ie JJ'afer Powers of 

 British Columbia, and in the Reports of the Scottish Meteoro- 

 logical Office, and will enable a comparison to be made between 

 the climate of a number of localities referred to in the course 

 of this paper and certain districts in Scotland. 



The regions in which I had opportunities of seeing forests of 

 the Douglas fir included the larger part of the range of the 

 species; on the mainland of British Columbia from Banff on 

 the eastern slopes of the Rocky Mountains to Vancouver 

 City ; in various parts of Vancouver Island, and in the coast 

 forests of Washington, Oregon, and California, as far south- 

 wards as the Redwood Belt north of Crescent City. The 

 regions to which the Glauca form are stated by Professor 

 Henry to be indigenous, viz. : the Central and Southern 

 Rocky Mountains from Eastern Montana and Wyoming to 

 Arizona and Northern Mexico, had to be omitted from the 

 itinerary because of time considerations. The Glauca form 

 has, however, been planted in a great many places in Great 

 Britain, usually as small woods, and for this reason as well as on 

 account of its being at one end of a series of geographical races 

 or varieties, and my seeing a tree of the Douglas fir in Canada 

 that, if not the Glauca form, is closely related to the latter, I 

 shall take the opportunity of referring to it along with the 

 other Douglas firs. Cones were not collected in all the forests 

 visited containing Douglas fir as a constituent species, owing 

 to the difficulties which would have been entailed by the 

 transport of more than very limited supplies. All the cones 

 were gathered in four or five localities, Craigellachie, Kamloops, 

 Hope, and Vancouver Island (Nanaimo and Bainbridge) — a 

 selection of localities which may be regarded as affording a 

 fairly representative sample of the varied forest conditions met 

 with in the Douglas fir forests of British Columbia. The seed 

 extracted from the cones was sown out in the nurseries at 

 Craibstone in the spring of last year. No herbarium specimens 

 were collected apart from the cones, and I am therefore not in
