It is useful for rustic-work, and even in a green state furnishes 
excellent fuel. It is easy to work. The sap-wood is white, and 
the heart-wood of a pinkish colour. 
Specific gravity, .727 and .773 (say between forty-five and 
forty-eight pounds per cubic foot); yield of charcoal per cent., 
26.125; of crude wood-vinegar, 44.75; and of tar, 7.125. (Mueller.) 
Two slabs of this wood in the Technological Museum, which 
have been seasoned over twenty-five years (having been exhibited 
at the London International Exhibition of 1862), have weights 
which correspond to 52lbs. 70z. and 53lbs. 70z. respectively per 
cubic foot, and a third, exhibited under the name A. adenophora, 
weighs no less than 62lbs. 140z. per cubic foot. Diameter, 12 
to 18in.; height, 40 to soft.

Since the above was written Baron Mueller has conceded 
specific rank to this so-called variety. Diameter, 6 to gin.; 
height, 20 to 3oft. 
TIMBER EXPERIMENTED UPON BY VICTORIAN TIMBER Boarp, 1884. 
The samples tested were each 7ft. in length, by 1 fin. square ; 
the distance between the bearings was 6ft.; and the weight was 
gradually applied in the centre until the sample broke. 
Local name, Silver-wattle ; botanical name, A. decurrens var. 
mollis, (A. mollissima) ; locality where grown, Waterloo, Victoria. 
Approximate date when the timber was cut, April, 1883; dimen-
