Bark of the Towhai, from which an extract is obtained. Timber of the Towhai. Two samples of Extract of Hinau. The Hinau Elceocarpus dentatus is a largo forest tree, abundantly diffused throughout most parts of New Zealand. The bark has been successfully used in tanning operations. The natives also use it in producing the beautiful black dye for their flax work, for which purpose the bark is first bruised and boiled for a short time. When cold, the flax, if put into the mixture, where it is left for two days, after which it is taken out and steeped thoroughly for two days in red swamp mud, rich in peroxide of iron, when it is removed and dried in the sun. The Hinau can be used in the manufacture of ink, by dissolving a small quantity of the extract in water, and adding a little rust of iron. As it contains; neither corrosive acid nor gum, the pen is neither injured nor clogged. The extract of Hinau can also be used instead of logwood. The extract of Towhai is much more astringent than that of Hinau, and needs only to be introduced to be accepted by tanners.
