TIMBER 
As showing the density of the timber, a paving block 
wliich had been lying in a room nine or ten years and 
weighed 3 lbs. 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, jarrah 
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 lbs. per cubic foot when cut, and 48 lbs. 
when dry; 55 lbs. when fairly seasoned. The paving block 
above referred to weighed 50 lbs. per cubic foot. 
Karri {E. 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. 'J'he 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 gi ound-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 lbs., when fairly seasoned 63 lbs., 
and when dry 50 lbs. j^er cubic foot. 
Although jarrah and karri are easily distinguished when 
growiyg by the dilierence in the barks, the former having
