YELLOW CEDAR 



Rays. Need lens, size 5, rather large for a Conifer : orange- 

 coloured : straight, rapidly tapering : large ones rare, if any : 

 5-10 per mm. : cells round, laxer than the ground-tissue : not 

 regularly spaced. 



Rings. Clear even if not prominent : boundary apparently or 

 actually a band of Autumn wood : some contrast, but nothing 

 pronounced : the Summer and Autumn wood melt into one 

 another. 



Pith. Round, about 0*5 mm. diameter, of large spherical 

 brown and white cells. 



Radial Section. Rays readily visible, brown flakes : dull. 

 Rings just traceable, fine lines. Ground-tissue bright, but 

 scarcely crystalline. 



Tangential Section. As the Radial, but the rays are just visible 

 with lens : brown lines about o - 2 mm. high. 



Type specimens from a log sent to the Indian and Colonial 

 Exhibition.

Uses, etc. " Not strong : easily worked : very durable in con- 

 tact with the soil, . . . timber is manufactured from the buried 

 trunks of this species dug from peat swamps . . . boat-build- 

 ing, wooden-ware, cooperage, shingles, telegraph and fence posts 

 and railway-ties " (100). " Sometimes exceeds 6 ft. in diam." 

 (66). " Very durable and credited with resisting the teredo 

 . . . greatly valued for interior finishing, and commands a 

 higher price than either the Douglas Fir or Arbor vitae " (65).

 the Indians) . . . liable to shrink lengthwise unless well
