King William 



IV. TIMBER. 



(a^ Economic. 



The timber is pale-coloured, and much harder than the 



Pine." It planes well and has an attractive figure, is close, 3et short grained, 



and should make good panels. Apparently it is suitable for \dolin sounding boards. 



Though a somewhat harder wood, it has not a reputation for durability 

 equal to that of the " King William Pine." It has also a greater number 

 of knots and flaws. The local estimation of the weight of the timber is 370 super.

(6^ Anatomy. 



For all practical purposes this timber has similar anatomical characters 

 A\'ith those of Dacrydium Franklini (Huon Pine), except that pitted cells occur 

 in the tangential walls, other\\-ise a description of one is practicalh' a description 

 of the other. >^'Figures 2S1-283.) 



V. BARK. 

 The bark is hard, thin, and scaly, the surface of the scales being smooth. 



(fl) Anatomy. 

 This bark has a peculiarit\- of structure quite unique compared to that 

 of an\" of its congeners examined. The chief points of distinction are — first the 

 occurrence of an inordinate number of sieve tubes \\-ith their accompanying 

 sieve plates ; and, secondly, the want of an}" regular stratification of the various 

 cells, tubes, and fibres as obtains in many other Conifer barks. Sieve tubes occur 

 throughout almost the whole bark substance, both inner and outer, the only place 

 where they really do not occur is in the periderm layer in the "outer cortex. 

 There appear to be two kinds of tubes, those \\ith elongated narrow cells 

 with onh" one sieve-plate in the diameter, and those with more than one siere- 

 plate in a transverse wall, and are much broader and shorter cells than the
