The Towai (Weinmannia racemosa) is an indigenous tree largely distributed over the hilly lands in many parts of New Zealand; it is often to be met with four or five feet in diameter, and from thirty to sixty feet in height. It grows frequently in clusters united at the base in a large tabular stoloniferous root, and in numerous instances round Mount Egmont the tree forms a natural bridge over the stream, as it first grows upright on the bank, and then gradually inclines over until its top reaches the land on the other side, there it rests, a forest of young trees springing up vertically from the prostrate trunk. A zone of thirty miles, three miles in width round the high lands of Mount Egmont is clothed exclusively with Towai, whilst throughout the whole district the banks of most of the rivers will yield a large supply. A reference to the map will show the distribution. The Extract is unusually rich in Tannin and forms good leather, and as a dye will yield all the shades obtainable from Gambier. It can be cheaply rendered.

In case B the first four Extracts are astringent of greater or less value.

No. 11.—Hinau (Elœocarpus Dentatus) is of sufficient importance to deserve a special notice.

page 13

The Hinau is an evergreen forest tree of considerable dimensions. The bark is used by the natives in dyeing black their beautiful flax mats. The flax after a soaking in a hot fusion of the bark is buried for a time in the red iron mud so abundant in the stagnant pools. The Hinau can only be considered of value as a dye, yielding yellow buffs and blacks.

No. 12.—Is an Extract of the Pukatea (Atherosperma Novae Zealandæ). It is a valuable tonic, much in use amongst the Maoris as a remedy for neuralgia. In selecting a tree for stripping, they always take one that has been exposed to the fullest effects of the sun's rays.
