6— BLACKBUTT (Euc. patens). 



A tree attaining a height up to 100 feet, with a bole of 40 to 50 feet, and up 

 to six feet in diameter. The bark is persistent, hard, fibrous, deeply fissured and 

 dark grey in colour. Considerable difficulty is experienced by most people in 

 distinguishing this tree in the forest from Jarrah. The two trees are certainly 

 very similar in general appearance. The bark of the Blackbutt is more deeply 

 fissured than the Jarrah, and has the appearance of having been combed. The 

 ridges of these fissures are usually black, while the indentations are of a brownish 

 grey. The leaves are smaller than the leaves of the Jarrah; and of a bluish-green. 

 In case of doubt, it is advisable to refer to the fruits. These are somewhat smaller 

 than the Jarrah fruits, but the rim which forms the top margin of the fruit is 

 quite narrow, and the ovary is slightly sunk and flatter. 



Weight per cubic foot (green) — 691bs. 



At 12 per cent, moisture — 541 bs. 



Transverse strength — 14,2001 bs. per square inch, 



Tensile strength- — 15,7001bs. per square inch. 



About the same weight and strength as jarrah, but a pale yellow-coloured 

 wood. It is not plentiful, but is to be found in small patches in the gullies and 

 pockets of alluvial soils, between laterite crests of hills. It is useful for many pur- 

 poses and particularly for farm implements and railway truck building.
