Some weeks ago it was suggested in those columns that the bark of a number of our native woods might be utilised for the production of dyes, as it is common knowledge that the natives liave for many years employed them for tlie dyeing of mats, etc. 3t is satisfactory to know that the subject is receiving the earnest consideration of the Government Chemist, Mr B. O. Aston, F'.T.(\, lias discovered h.v experiment tluit valuable vegetable dyes may be proenred'hy the treatment of the bark of the native tree with the botanical name of Ooprosma. .Mr Aston states that preliminary tosts show that there, is reason to believe that dyes closely .similar to, if not identical with, those of madder, are to he obtained from the Ooprosma, which is a shrub to be found in almost every part of the Dominion!. There is reason to think that a. most important industry might b - established in Xew Zealand in the manufacture of vegetable dyes.
