I have examined a sample of bark called “ Green Wattle,” from Bell’s Creek, 
Araluen, N.S.W. 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 result:—Tannic acid, 3123 per cent.; 
extract, 6415 per cent. It is smooth, compact, yields a liglit-colonred 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. 
Bark from Eden, stripped in November, gave 30'25 per cent of tannic acid> 
and 5D65 per cent of extract. 
A specimen of “ Green Wattle-bark,” grown at Tombong, Snowy Biver, 
N.S.W., was collected in March, 1889. It was obtained from trees 20 to 30 feet 
high, with diameters 6 to 15 inches, and was grown in granite country. It yielded 
(April, 1890) 2DG3 per cent, 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 barks of this variety. In spite of the 
badly-selected sample, the analysis shows that it is full of promise. 
Northern Barks. 
Bark from Booral, stripped in June, yielded 28'52 per cent, of tannic acid, 
and 56‘1 per cent, of extract. A second sample from the same place gave 27'5 per 
cent, of tannic acid, and 57‘1 per cent, of extract. 
A sample from Raymond Terrace, collected in December, gave 33 - 20 per cent, 
of tannic acid, and 5T5 per cent, of extract, showing that good barks can come from 
the north. 
Bark from Gosford, stripped in July, from four-year-old trees, gave 22 per 
cent, of tannic acid, and 464 per cent, of extract. 
Victoria and Queensland. 
We now turn to the other States. Eollowing are two barks from Casterton, 
Victoria, stripped in January, and analysed in the following March. A picked 
specimen, said to be the best obtainable, gave the excellent result of 3G25 per cent, 
of tannic acid, and 61 - 65 per cent, of extract, practically the same as that of the 
Nerriga, New South Wales, bark, already noted. 
A second specimen of the same district, sent as an average sample, gave 
29 per cent, of tannic acid, and 54‘45 per cent, of extract. 
The following analysis of a Queensland sample was given by the 
Commissioners of that State at the Colonial and Indian Exhibition of 1886:— 
Tannin, 15 - 08 per cent.; extract, 26 - 78 per cent. This bark becomes undoubtedly 
inferior in the warmer climate of Queensland.
