WATTLES AND WATTLE-BARKS.

7. Acacia sentis , F.v.M., B.FL. ii., 3G0. 
A specimen of a dirty grey scaly bark, -;J of ail inch thick, from Ivanhoe, 
N.8.W., yielded the author 1*8.02 per cent, of extract, and tannic acid 0*32 
percent. * ( Froc. R.S., N.S.W. , 1887, p. 29.) 
A second sample from Cobbatn Lake, Milparinka, N.S.W., was analysed 
by the author. August, 1888. ( Proc. R.S., N.S.W. , 1888, 26*8.) Tree, 
height 15 to 20 ft., diameter 4 to G inches, collected, August, 1887. It 
yielded extract 33*82 per cent., tannic acid 10*20 per cent. This hark would 
scarcely be taken for the product of a dry country wattle, it is from a 
younger tree to that already described, and is almost perfectly smooth and of 
a light brown colour. The collector reports “ when fresh it; is of a beautiful 
bright green coloui*, much: like the bark of A. dccurrcns. [ have found it 
easier to strip than any other bark I have stripped jet out west.” It is very 
compact. Average thickness, {■ inch. 
An inland, desert species. In all the colonies except Tasmania. 
8 . Acacia falcate, Willfl., B.Fk, ii., 3G1. Called “Bastaud Myall,” in the 
Braidwood District, N.S.W. It also goes by the names of “ Hickory,” 
“ Sally,” and “ Lignum-vife.” It was formerly the “ Wcc-tjellan ” of 
the aboriginals of Cumberland and Camden, N.S.W. (Maearthur.) 
It is said to yield a good tanning bark, but it is usually of rather small size 
and not likely to be of importance to tlie tanner. 
On the coast districts, and on to the dividing range, in New South Wales 
and Queensland; its farthest southern locality is the Shoalhaven Itivcr. 
9. Acacia penninervis. Sieb., B.Fl.,ii., 362. A “ Blackwood,” usually called 
“ Hickory” or “Mountain Hickory,” from Braidwood to the Victorian 
border. 
The hark contains 17*9 per cent, of tannic acid, ar.d 3*S per cent, of gallic 
acid. (Mueller.) The following analysis is given by tlie Queensland Com¬ 
missioners. Colonial and Indian Exhibition, 18S6:—Tannin, 14*19 percent. ; 
extract, 33*00 per cent. Specimens from Monga, near Braidwood, N.S.W., 
yielded the author (a) from the bark of the twigs, 22*SS per cent, of extract, 
and 16 24 per cent, of tannic acid; (A) from the bark of the trunk, 45*5 per 
cent, of extract, and 10*90 per cent, of tannic acid. The trunk-bark is 
smoothish, of a dirty brown colour; average thickness $ inch. The outer 
bark peels off in scales ; the bark is very fibrous. The bark of the branches 
is smoother than that of the trunk, yet not perfectly smooth, is of a dirty 
grey colour, and A inch in thickness. {Froc. R.S ., N.S.W., 1887, 30.) 
The following bark of tlie same species is so different from the preceding 
that I describe it in detail. It is a practical illustration of the variability in 
appearance and composition of some wattle-barks, and shows the necessity 
of supplying the fullest particulars in regard to barks, where it is desired 
that full information in regard to what is already known of any given species 
of wattle may be afforded. This sample was collected at Brown’s Camp, 
Delegate, N.S.W., in April, 1889, and analysed tlie following April. The 
trees were from 30 to GO ft. high, with the large diameter of 1 to 2 ft. They 
grow in granite soil. My samples yielded 55*2 per cent, of extract with the 
excellent result of 34 per cent, of tannic acid. This bark is over J inch thick, 
and therefore one of the thickest wattle-barks I have seen. The outside is 
rugged, almost like an ironbark, but the bark cuts solid, contains compara¬ 
tively little fibre, analysis shows it to be one of the richest in tannic acid, 
while the trees are abundant and attain a large size. I recommend this tree
