b. Momba, Wilcannia.—Height, 30 to 40 feet; diameter, 12 to IS inches. 
Collected August. 1817 ; analysed September, 18S8. Not flaky on the out¬ 
side like No. 1, but a harder, bonier bark, more rugged, but obviously a 
promising bark. Thickness, up to 1 inch. Extract, 33T per cent. ; tannic 
acid, 13*51 per cent. 
A sample of this bark, from the Lachlan Liver, New South Wales, vid 
Hay, which has been in the Technological Museum 5 years, is a good specimen 
of this bark, being fairly smooth, close, compact, and containing com¬ 
paratively little fibre. It was analyzed May, 1890, and found to contain 
32*75 per cent, of extract, and 15’L per cent, of tannic acid. 
This species is undoubtedly worthy of conservation, and even culture, in 
the dry interior when it is found, particularly as the barks there are usually 
so poor in tannic acid. The blacks are aware of the value of this tan-bark, 
as they use it for tanning wallaby and other skins. 
An interior species, found in all the colonies except Tasmania. Habitat, 
chiefly on banks of creeks and water-courses.

Mueller to a variety of A. Uni folia , Willd. 
This is called 44 Grey ” and 44 Black Wattle ” near Sydney, hut dealers 
will not have it, and it hardly pays to cut up and pass with better bark. A 
sample of a black bark, stained, leopard-like, with whity-green patches, and 
bearing lichens, yielded the writer 18*03 per cent, of tannic acid, and 42*35 
per cent, of extract. It was from Penrith, N.S.W 
A sample from Penshurst, Hlawarra line, near Sydney, gave the author 
(Proc., R.S ., N.S.W., 1888, p. 209) 39*98 per cent, of extract, and 14*42 of 
tannic acid. Height of tree, 10 to 15 feet; diameter, 1 } to 2 inches; 
collected September, 1887 ; analysed August, 1SS8. A light-coloured bark, 
very thin, of the thickness of stout brown paper, and reminding one strongly 
of that of A. longifolia. As this was but from a sapling, the Penrith bark 
gives a fairer criterion of the value of bark of this species. 
Pound in Victoria, New South Wales, and Queensland. On the Snowy 
Mountains it occurs at elevations from 4,000 to 5,000 feet. It is an eastern 
species, found principally in the coast districts. 
17. Acacia podahj rue folia , A. Gunn., B.FL, ii., 374. Sometimes called 
44 Silver Wattle.” 
The bark is used in tanning, giving a light colour to leather. The follow¬ 
ing analysis is given by the Queensland Commissioners, Colonial and Indian 
Exhibition, 1886 :—Tannin, 12*40 per cent.; extract, 29*50 per cent. 
(Bailey). 
Northern New South Wales and Queensland. 
18. Acacia vest it a , Tver, B.Fl., ii., 375. 
Bark from near Bombata, N.S.W., yielded the author 50*82 per cent, of 
extract, and 27*96 per cent, of tannic acid (Proc. R.S ., N.S.W.. 1887, p. 89). 
It grew on limestone country, and was from a tree 18 inches in diameter. 
Analysis of a second sample from the same district gave an even better 
result, viz.: — 64*51 per cent, of extract, and 33*2 per cent, of tannic acid. 
This is very similar in appearance to the bark of A. decurrens , for which it 
might he substituted without detriment. It is a most useful hark, hut,
