Ob ON SOME N.S.W. TAN-SUBSTANCES. 



Vernacular Name — " Wait-a- while," (a low -spreading Lush, 



which has been suggested as suitable for hedge planting. 



The vernacular name is a delicate allusion to the 



predicament of a traveller desirous of penetrating a belt 



of it.) 

 Locality whence this particular specimen was obtained — 



Ivanhoe, via Hay, N.S.W. 

 Part of the Tree Examined — Bark. 

 Particulars of the trees (shrubs) whence it was obtained — 



Height, a few feet ; diameter 3 to 4 inches. 

 Collected 2nd October, 1886. Analysed 5th to 23rd July, 



1887. 



Bark from a very old tree. Yields abundance of a light- 

 coloured fibre. The description of the bark of A. rigens will apply 

 here, with the following differences. Average thickness of bark 

 \ inch. Colour lighter and of a yellowish tint. Yields a brightish 

 yellow powder admixed with a few brown particles. Affords a 

 pale yellow-coloured solution. This circumstance, in the case of 

 a Wattle would of course pronounce it obviously worthless for 

 tanning purposes. 



Extract. — Dissolves in water at 100° C. to the extent of 10*56 

 per cent. 



C atechu-tannic acid — 4 "4 per cent. 



21. Acacia rigens, A. Cunn , N.O. Leguminosa?, B. Fl. ii., 337.

chiefly in arid country. 

 Vernacular Names — "Nealie"or "Needle-bus)]." 

 Locality whence this particular specimen was obtained — 

 Ivanhoe, via Hay, N.S.W. Very plentiful in some places. 

 Part of the Tree Examined — Bark. 

 Particulars of the trees whence it was obtained — Height 12 



to 15 feet, diameter 6 to 8 inches. 

 Collected 6th September, 1886. Analysed 5th to 20th July,

This bark is obviously from a very old tree, and consists almost 

 entirely of fibre, the whole bark separating with the slightest 

 effort into ribbons of coarse tying material. It is deeply fissured, 

 and the prevailing colour of the outside is a dirty grey. The bark 

 possesses so little coherence that an exact determination of its 

 thickness would be extremely difficult ; its average thickness may 

 be set down at \ inch. When finely divided it has the appearance 

 of chopped hay, interspersed with reddish-brown particles.
