Construction
The canoes are made by carving from solid logs, usually of red cedar but in some areas of Sitka spruce or cottonwood. Typically these boats were widened beyond the original diameter of the log by the spreading of the steam-softened sides. Spreading does more than widen the canoe; it introduces major changes of form throughout the hull which the canoemaker must anticipate in carving the log. The straight and level gunwales bend smoothly out and down, while the ends rise, forming a graceful sheer and transforming a rigidly narrow, hollow trough into an elegant watercraft.
In order to spread without splitting, the walls of the hull are made remarkably thin. When the hull is completely carved, water is poured into it to a depth of six inches or so, and heated to boiling with red-hot rocks. The resulting steam is confined by covering the open hull with mats. The hot rocks are replaced as needed to keep the water at a boil. The softened sides, heated through by the steam inside and fires outside, begin to move outward, aided by the weight of water and rocks pressing down in the centre. Spreading sticks are tapped into place between the gunwhales, and are moved towards the ends and increased in length in the centre as the sides flare outward. When the planned beam and form are reached, the canoe is allowed to cool, the water is removed, and the thwarts, bow and stern blocks, and gunwhale caps are fitted and fastened in place.
Large travelling and war canoes were often painted with designs associated with the names of the canoes or the crests of the owners.

Famous quotes containing the word construction:
“When the leaders choose to make themselves bidders at an auction of popularity, their talents, in the construction of the state, will be of no service. They will become flatterers instead of legislators; the instruments, not the guides, of the people.”
—Edmund Burke (1729–1797)
“The construction of life is at present in the power of facts far more than convictions.”
—Walter Benjamin (1892–1940)
“There is, I think, no point in the philosophy of progressive education which is sounder than its emphasis upon the importance of the participation of the learner in the formation of the purposes which direct his activities in the learning process, just as there is no defect in traditional education greater than its failure to secure the active cooperation of the pupil in construction of the purposes involved in his studying.”
—John Dewey (1859–1952)
