WATTLES AND WATTLE-BARKS. 
cent, of extract, while a second sample, from an older tree, gave 35'3 per 
cent, of tannic acid, and 59*05 per cent, of extract. Both were grown near 
Penrith, New South Wales. 
I have examined a sample of bark of this species, called “ Green Wattle,” 
from Bell’s Creek, Araluen, New South Wales. It was from trees 25 to 30 
feet high, with diameters from G to 18 inches, was grown on granite soil, 
and was collected in November, 1888. In April, 1890, it was analysed with 
the following resultTannic acid 31*23 per cent., extract 01*15 per cent. 
It is a smooth compact bark, yields a light-coloured powder with some fibre, 
is a quarter of an inch thick, and is to be ranked with the best of our New 
South Wales barks. 
A specimen bearing the same local name, and grown at Tombong, Snowy 
River, New South Wales, was collected in March, 1889. It was obtained 
from trees 20 to 33 feet high, and with diameters 0 to 15 inches, and was 
grown in granite country. It yielded (April, 1890) 21*63 percent, of tannic 
acid, with 45*8 per cent, of extract. This sample is hardly fair to the 
species. It is rather thin, rugged, covered with lichens, and rather more 
fibrous than the generality of A. mollissima barks. In spite of the badly 
selected sample, the analysis shows that it is full of promise. 
A specimen of wattle-bark was received in this Museum in the year 1883 
from a South Australian firm, labelled A. dealbata , Mount Crawford District, 
South Australia, containing 29*25 per cent, of tannic acid, according to an 
analysis by Mr. Thomas, of Adelaide. Now A . dealbata is not found in that 
Colony, and I scarcely hesitate to place the bark under A. mollissima . I 
analysed this bark in April, 1890, and found it to contain 30*73 per cent, 
of tannic acid, with 55*5 nor cent, of extract. Doubtless a portion of this per¬ 
centage is owing to careful storage during seven years. It is a solid bark, a 
little scaly on the outside, and very much like A. mollissima , or A. dccurrcns 
hark in appearance. Thickness, A-inch. It yields a good powder, with but 
little fibre. 
A sample of this bark, received May, 1890, and analysed the following 
month, was found to contain 34*85 per cent, of tannic acid and 01*5 of extract. 
It came from Burragorang, New South Wales. It is thicker than most 
harks of this species, and is beginning to he scaly on the outside. Were it 
not for that defect it would be a splendid bark. It was allowed to remain a 
year too long on the tree, a fault not usually to he found with Now South 
Wales bark getters. 
Round in all the colonies except Western Australia; a coast, highland, and 
mountain species, not extending far inland.

The bark of this variety is used by the local tanners, and is spoken of 
fairly well as regards percentage of tannin, hut is not much liked on account 
of its being considered too hard and fibrous, and therefore difficult to break 
up in the mill. 
It is a common belief amongst tanners (and at present I am not prepared 
to say what basis of truth it has) that barks much subjected to frost and 
snow are much richer in tannin than those not so subjected. The present 
sample is from a tree grown in a very eokl district. It was collected
