476 AUSTRALIAN NATIVE PLANTS. 
With the exception that it is a shade darker, it cannot be 
distinguished from the preceding. 
This species is, with very little doubt, the timber experimented 
upon in the Sydney Mint experiments under the name of “Red 
Ironbark.” It is described as hard, close-grained, of great 
strength and durability, and valuable for ship-building, engineering 
works, etc. It is said, however, to be readily attacked by the 
white ant. The specimens came from Berrima, New South 
Wales, the tree was 30ft. to the fork, and 30in. in diameter. 
Specific gravity, 1.167; value of E, 521,300; of S, 3951. In the 
same experiments the ‘“ Smooth-barked Ironbark,” from Brisbane, 
must be from this species, as the wood displays no important 
differences from authenticated specimens. It is described as 
“A strong and durable timber, and well-adapted for building 
purposes, shingling, etc.’ The tree was 35ft. to the fork, and 
25in. in diameter. Specific gravity, 1.176; value of E, 604.800; 
of S, 2898. 
Height, up to 200ft., but this is exceptional. 
Spencer’s Gulf (South Australia), through Victoria and New 
South Wales to Southern Queensland. 
286. Eucalyptus longifolia, Zzvk, (Syn. Z. Woollsti, F.v.M.); 
N.O., Myrtacez, B.FI., iii., 226. 
This tree commonly bears the names of ‘‘ Woolly Butt” and “ Bastard 
Box,” but usually the former. 
This wood is in request for fuel, but is not much valued as a 
timber because of its gum-veins. When sound, it is sought after 
for wheelwrights’ work. (Sir W. Macarthur.) Other authorities 
have referred to its durability for fences. Posts are said to have 
remained undecayed in the ground for twenty years. It is used 
for felloes, shafts, spokes, agricultural implements, house-building, 
etc. Its specific gravity is 1.187, the weight of a cubic foot of 
dried wood being 683lb. 
The following four samples are in the Technological Museum. 
They are all called ‘ Woolly Butt ;’’ the first is from Victoria, the 
others from New South Wales :—
