474 AUSTRALIAN NATIVE PLANTS. 
heaviest of our native woods, and has a peculiarly thick and rugged 
bark, with deep longitudinal fissures, which is very characteristic. 
It possesses great strength and tenacity, and has a close and straight 
grain, on which account it is highly useful to the coachmaker and 
wheelwright for the poles and shafts of carriages, and the spokes 
of wheels. Its greasy nature also renders this wood very service- 
able to the millwright for the cogs of heavy wheels. It is also 
valuable for many purposes in ship-building, and constitutes one of 
the most imperishable of our timbers.” 
Following are brief descriptions of timbers of this species in 
the Technological Museum of Sydney :—‘‘ Red-flowering Iron- 
bark,” or ‘‘ Black Ironbark :’* Of very dark red colour, close in 
the grain, and fairly good to work. A useful wood where strength 
is required. It is very heavy and hard. (Victoria.) (Cat. 
Timbers, Technological Museum, Melbourne.) ‘Red Ironbark :” 
Diameter, 2ft. Colour, dark reddish-brown, full of shakes, very 
heavy, and difficult to dress. (Eastern N.S.W.) “Red Ironbark:’’ 
Diameter, 2ft.. Colour, rich red. Shelling in concentric layers 
near the heart, and full of shakes. Very difficult to dress. (New 
South Wales.) ‘Red Ironbark :”” Diameter, 2ft. Colour, brown.. 
Full of shakes ; works fairly well, splits tolerably freely. (New 
South Wales.) The last two samples have been cut at the wrong 
season. 
The three following timbers (also in the Technological 
Museum) must also be referred to this species :—1. No. 3 (Lond., 
1862); No. go (Parts, 1855). ‘‘ Ironbark” of Illawarra, and 
“Barremma” of the aboriginals. Diameter, 36 to 60in.; height,. 
80 to 130ft. “Of the highest reputation for strength and 
durability.”’ Itis of a dark red colour, figured in stripes, heavy, 
tough, hard, and difficult to work, strong, and very durable. 
2. No. 5 (Zond., 1862); No. 1374 (Parts, 1855), from Appin, 
New South Wales. It is of a dirty streaky-brown colour, very 
heavy, cross-grained, and tough, and not very good to work. 
3. No. 6 (Zond., 1862); 137¢ (Paris, 1855), from the upper part 
of the Bargo Brush. Diameter, 24 to 36in.; height, 60 to 8oft. 
* This specimen was received from Victoria, labelled £. sideroxylon, and with the 
vernacular names given. Yet it cannot be the New South Wales species.
