Gkaylikg, Taranaki — Two Bamples of Extracts of llinau and Towai. The llinau is a large 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 dyo for their flax work ; 'lor which purpose the bark is first bruised, and boiled for a short time. When cold, the flax is 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 llinau 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 Towai is much more astringent than that of llinau, and needs only to be introduced to be accepted by the tanners.
