The wood to be bent was first soaked in the boiling water, or the water was poured over it by means of a birch-bark or other dipper. When the wood was thoroughly soaked with boiling water, bending began, and as it progressed boiling water was almost continuously poured on the wood. When the wood had been bent to a desired form, it was secured in shape by thongs and allowed to cool and dry out, during which it would take a permanent set. Hard bends, as in gunwale ends and stem-pieces, were made by this means, usually after the wood had been split into a number of laminations in the area of the greatest bend. When the piece had been boiled and bent to its required form, the laminations were secured by wrapping them spirally with a thong of inner bark (such as basswood), of roots, or of rawhide. Flat stones were used to weigh down bark in order to flatten it and prevent curling. Picked up about the canoe-building site, they had one smooth and fairly flat surface so that no harm came to the bark, and were of such size and weight as could be handled easily by the builder. Smooth stones from a stream appear to have been preferred. In preparation for building a canoe, the pins, stakes, and poles which were of only temporary use were cut or burned down in the manner mentioned and stored ready for use. Bark containers were made and filled with spruce gum, and the materials used in making it hard and durable were gathered. The building site was selected in the shade, to prevent the bark from becoming hard and brittle, and on ground that was smooth, clear of outcroppings of stone, and roots, or other obstructions, and firm enough to hold the stakes driven into it. The location was, of course, usually near the water where the canoe was to be launched. [Illustration: Figure 13 Modern Hudson Bay axe]
