Bark

— On observing a statement that Bed Ash bark had been used for tanning, I investigated a sample from Bangley Creek, Cambewarra. It yielded 32.9 per cent. of extract, but only 8 per cent. of tannic acid, and the comparatively high percentacye of 3.75 of gallic-acid and impurities. The bark powders well, and yields but little fibre; the powder is, however, of a dark brown colour. The colour of the, liquor is deep for a bark yielding such a low percentage of tannic acid, but the liquid remaining after extraction of the tannic acid by hide powder is of a light reddishbrown colour, differing from the colouring matter of Acacia, barks, which is entirely removed by hide powder. This points to the fact that skins tanned with Red Ash bark would not turn out so dark a colour as would be expected from examination of the liquor.
