haps only to A. decurrens in importance for its yield of tanner’s 
bark ; the quality of the latter is even sometimes superior to that 
of the Black Wattle (A. decurrens, var. mollissima), but its yield is 
less, as the tree is smaller and the bark thinner. It is of rapid 
growth, content with almost any soil, but is generally found in 
poor sandy ground near the sea-coast, and thus also important for 
binding rolling sand. (Mueller, Select Extra-tropical Plants.) 
In part iii. of the Forest Flora of South Australia, by J. E. 
Brown, are some very interesting analyses of the bark of this tree 
by Mr. G. A. Goyder, Superintendent of the Crown Lands Labora- 
tory at Adelaide. The table is given herewith. The localities are 
all South Australian.
