OREGON PINE 



Alternative Names. Douglas Pine, Fir or Spruce. Yellow or 

 . Red Fir in United States of America (n). Red Fir and Red Pine 

 in Canada (12). Yellow Pine of Puget Sound (92). 



Sources of Supply. Canada, British Columbia, United States 

 of America. 



Physical Characters, etc. Recorded dry-weight 30 f-38 lbs. per 

 cu. ft. (131). Hardness Grade 7, compare Deal. Smell faint if 

 any. Taste peculiar and flat : not vinous like Pinus Australis 

 (Pitch Pine). Burns well with a lively noisy flame : embers soon 

 die out in still air and leave a carbonized stick : strong tarry 

 smell. Solution almost if not quite colourless. 



Grain. Even, smooth, close, the pores being filled. Surface 

 partly of a resinous lustre and partly dull, in alternate bands. 



Bark. " Dark grey, rough, with thick firm ridges arranged in a 

 latticed manner : contains pitch-galls when young " (49). 



Uses, etc. " A tree from 200-300 ft. high by 27-120 inches in 

 diameter . . . wood strong, varying greatly : difficult to work : 

 durable. The two varieties, Red and Yellow, distinguished by 

 the lumbermen are probably dependent upon the age of the tree, 

 the former coarse-grained, darker coloured and considerably less 

 valuable than the Yellow Fir " (100). " Spars, flooring, works 

 of construction, sleepers, piles, bridges, ships. Subject to the 

 attacks of the teredo . . . durable when buried " (2). " Ship- 

 building, bridge work, wharves, fencing, furniture " (65). 

 " Good, but not equal to Pitch Pine for paving " (92).

Colour. Bands of a resinous-brown colour, alternating with 

 lighter brown bands. " Splint yellowish " (86). Much lighter 

 than the heart-wood. 



Anatomical Characters. Transverse section. (Compare No. 

 242.) 



Pores. Present as resin ducts : small, size 4 : few, very thinly 

 scattered in the Summer and Autumn wood : imperfectly lined 

 with soft-walled cells : uniform : bleed at the cut end after a 

 time : absent over long stretches of the ring : clustered, single 

 or paired. 



Rays. Just visible, size 5-6, or rather more : 3-9 per mm. : 

 denser than the ground : yellowish : long, tapering at length : 

 interrupted by or running round the ducts : large ones frequent, 

 long and bold, occasionally as large as size 5. 



Rings. Very clear and prominent : the Summer and Autumn 

 wood sharply separated with much contrast between them. 

 Autumn wood very resinous and dense, always a band and some- 

 times very broad : contour undulating.
