214 TIMBER 



As showing the density of the timber, a paving block 

 which had been lying in a room nine or ten years and 

 weighed 3 Ibs. 14 ozs. only absorbed 2 ozs. of water after 

 an immersion of twenty hours, and this was not increased 

 after the timber had been kept in water for a total period 

 of forty hours. According to Indian. Engineering, i&rr&h 

 has recently been used in place of teak on some Govern- 

 ment buildings, as it was cheaper and found quite as 

 satisfactory. 



Weight about 68 Ibs. per cubic foot when cut, and 48 Ibs. 

 when dry; 55 Ibs. when fairly seasoned. The paving block 

 above referred to weighed 50 Ibs. per cubic foot. 



Karri (K. diver sicolor) is a taller tree than jarrah, being 

 sometimes branchless for 100 to 120 ft. ; in Warren River 

 district it has been met with 300 ft. high and 180 ft. to the 

 first branch. The forests cover 1,000,000 acres from Cape 

 Hamlin to Torbay. The timber is of reddish brown colour, 

 hard and dense, fairly elastic, and closely resembles jarrah, 

 but is not so easily wrought. It is not well suited for damp 

 situations, and when used for telegraph poles it decays at 

 the ground-line. It is used for much the same purposes as 

 jarrah, and can be had in logs up to 100 ft. in length and 

 planks of great width. Specimen planks nearly 5 ft. wide 

 have been obtained. Karri makes excellent wearing paving 

 blocks, but is not so much used for this purpose as jarrah ; 

 it shrinks much more. It is much appreciated for 

 wagon frames. For very long piles it will stand hard 

 driving better than jarrah, being larger in fibre and more 

 elastic. 



Weight when cut 72 Ibs., when fairly seasoned 63 Ibs., 

 and when dry 50 Ibs. per cubic foot. 



Although jarrah and karri are easily distinguished when 

 growing by the difference in the barks, the former having
