WATTLES AND WATTLE-BARKS. 51 



A further sample from Stroud (in the same neighbourhood) collected in 

 January, gave 27*75 per cent, of tannic acid, and 48'9 per cent of extract. 



This a coast species of New South Wales and Queensland. It does not 

 extend further south in our Colony than the Ulladulla district. It is 

 frequently a large tree and yields much bark. 



Memorandum. This wattle maybe easily recognised by the two prominent 

 veins on the leaf. 



31. Acacia flav csc ens, A. Cunn., B.PL, ii, 391. 



This bark contains 10'2 per cent, of tannin. (Staiger.) Queensland. 

 35. Acacia longifolia, WillcL, B.P1. 5 ii, 897. 



Sydney, " GOLDEN WATTLE," " White Sallow or Sally," Hickory," &c. 



The bark of this tree is considered in Queensland to be only half as good 

 as that of A. decurrens. It is used chiefly for sheepskins. The following is 

 an analysis of this bark : Tannin, 12*67 per cent. ; extract, 32 05 per cent. 

 (Staiger.) A specimen from Canibewarra, N.S. W., yielded the author 18'93 

 per cent, of tanuic acid, and 30*55 per cent, of extract. (Proc.~R.S.>N.S.W., 

 1877, p. 90.) Other specimens (a) from Oatley's grant, near Sydney, and (5) 

 Hyde, near Sydney, yielded the author (loc. cit., p. 190), 15*34 and 15'99 per 

 cent, of tannic acid respectively, and 24*91 and 23'53 per cent, of extract 

 respectively. Both were from much younger trees than the specimens from 

 Cambewarra. 



Speaking generally, this is a smoothish, thin, sub-scaly bark, not in high 

 repute. It yields a light-coloured powder. 



A sample from Tantawanglo Mountain, near Candelo, N.S.W., and locally 

 known as "Hickory," was examine! by me, and found to contain 5 per cent, 

 of tannic acid, and only 14 per cent, of extract. It was collected in July, 

 1889, and analysed in April, 1890. It was from trees 20 to 50 feet high, 

 with diameters of 4 to 12 inches, growing on chocolate soil. The trees of 

 this species attain rather large dimensions in this district. The bark becomes 

 coarser and larger, but it is one mass of fibre, and practically useless to the 

 tanner. 



South Australia, Tasmania, Victoria, N"ew South "Wales, Southern 

 Queensland. 



35. The bark of the variety SopJioroe is used for tanning light skins in 

 Queensland, but as it is comparatively weak in tannin it fetches but a low 

 price. It is there called " Black Wattle." (Bailey.) Mr. W. Adam informs 

 me that Sydney fishermen often tan their sails and nets with this bark, and 

 are well pleased with it, the articles being pliable after use.
