STONE PINE 



Pin Maritime, Pinaster, Pin de Bordeaux, Pin de Landes (129). 

 Gewoon Den : Mannetje Danne Boom in South Africa (51). 



Physical Characters, etc. Recorded dry-weight 33-48 lbs. per 

 cu. ft. Hardness Grade 6, compare Beech. Smell none when 

 dry, but terebinthine when green or when worked. Taste flat if 

 any. Burns well without smell, embers glow in still air, a brown 

 resin expelled by the heat. " Very inflammable " (129). Solu- 

 tion quite colourless. 



Grain. Very smooth, fine and even. Surface easily soiled : 

 slightly frosted : the Autumn bands shiny. 



Uses, etc. " Naval work, carpentry, pit-props ... of little 

 value " (129). " A wood of medium quality " (69). 



Authorities. Hutchins (51). Westermeier (129), p. 43. 

 Mathieu (69). 



Bark. Dark-reddish violet : composed of large scales like the 

 Scots Fir, but more deeply fissured. 



Colour. White, whitish-brown to reddish-brown, with darker 

 resinous zones in alternate bands. 



Anatomical Characters. As those of Pinus sylvestris, No. 242, 

 which should be compared. The following trifling variations 

 may be constant. Transverse section : — 



Rays. Scarcely visible, size 5-6 or rather more : numerous, 

 7-10 per mm. : large or many-rowed rays rare. 



Horizontal Resin-canals, i.e. the larger rays, brown, spindle- 

 shaped, visible with lens. 



Radial Section. Rays readily distinguishable, prominent when 

 the wood is cleft : brownish, rather dull flakes. Rings exception- 

 ally bold : a striking contrast between Spring and Autumn wood, 

 but the Autumn fades into the Summer wood. 



Tangential Section. As the Radial, but the rays are minute 

 lines readily distinguishable with lens. Rings bold loops without 

 fringes, but less contrast of colour than one would expect from 

 the Transverse section. 



Type specimens from commercial sources and from trees known 

 before felling.
