On the model they are fastened here with treenails, and this is probably also the case on the large canoes. They are spread apart by cross pieces or floor timbers, flat rather broad boards laid across the keelson with their ends mortised into the bilge streaks. These are longest amidships and decrease regularly in length fore and aft. There were fifteen of them on Nikawáalu’s umiak. On the model they are pegged to the keelson and bilge streaks. The ribs are straight, slender, square timbers, eighteen on each side (on Nikawáalu’s umiak; the canoe photographed has fifteen). These are all of the same length, but fitted obliquely to the outer edge of the bilge-streaks in such a way (see diagram, Fig. 343b) that those amidships slant considerably outward while the others become gradually more and more erect fore and aft, thus producing the sheer in the lines. To these ribs, inside, a little below the middle of each, is fastened a streak on each side, of about the dimensions of the bilge streak, running from stem to stern, and the gunwales are fitted into the notched ends of the ribs, where they are secured by lashings of whalebone. These on Nikawáalu’s umiak were each a single round pole about 2 inches in diameter. Such long pieces of wood as this were probably obtained by trade from the Nunatañmeun. These extend about 2½ or 3 feet beyond the stem, to which they are fastened on each side by whalebone lashings, and meet at a sharp angle, being lashed together with whalebone. On the model, this lashing passes through holes in both gunwales and round underneath. The gunwales are fastened to the sternpost in the same way as to the stem, in both cases resting on the upper surface of the block so as to form a low rail, but project only 5 or 6 inches.

Between the post and the last pair of long ribs at each end are two pairs of short ribs running only from the gunwale to the inside streak. The frame is still further strengthened by an outside streak between the bilge streak and the inside streak, and Nikawáalu’s canoe had an extra streak of “half-round” willow outside of the latter. The thwarts rest on the inside streak and are secured by whalebone lashings. The block or head of the stern-post serves as a high seat for the steersman. Crantz’s[443] description and diagram show that the frame of the Greenland umiak consists of essentially the same timbers, lacking only the two outside streaks.
The cover is made of the skins of the larger marine animals. Walrus hide is often used and sometimes the skin of the polar bear, which makes a beautifully white cover, but the skin of the bearded seal is preferred, the people from Point Barrow sometimes making journeys to Wainwright Inlet in search of such skins, which are dressed with their oil in them in the manner already referred to. We were informed that six of these skins were required to cover one umiak. They are put together in the same way as the skins for the kaiak and sewed with the same seam. The edges of the cover are stretched over the gunwale, and laced to the inside streak with a stout thong, which passes through holes in the edge of the cover. At stem and stern the cover is laced with a separate thong to a stout transverse lashing of thong running from gunwale to gunwale close to the edge of the posthead.
The cover is removed in the winter and stowed away on the cache frame or some other safe place (Mûñialu, when preparing to start for the spring deer hunt in 1883, carefully buried his boat cover in a snowbank) out of reach of the dogs, and the frame is placed bottom upwards on a staging 4 or 5 feet from the ground.
When they are ready to refit the canoe for the spring whaling, a hole is cut in the sea ice close to the shore, and the cover immersed in the sea water for several days to soften it, the hole being covered with slabs of snow to keep it from freezing up. Crantz[444] mentions a similar custom in Greenland. After removing the hair from the boat-skins “they lay them in salt water for some days to soften them again, and so cover the women’s boats and kajaks with them.” When not in use, the umiak is drawn up on the beach and usually laid bottom upward with the gear, spears, etc., underneath it, but sometimes propped up on one gunwale to make a shelter against the wind. This is a common practice in the camp at Pernyû, where there is usually at least one boat set up edgewise, sheltered by which the men sit to whittle and gossip.
In the whaling camp at Imêkpûñ in 1883, the boats which were not ready to go out to the open water were laid up bottom up with one end resting on a sled set up on its side and the other supported by a block of snow. They do not appear to be in the habit of using the canoe for a tent, as is said to be the custom among the more southern natives,[445] as they always carry a tent with them on their journeys. The umiak is propelled by paddles, oars, and a sail, and in smooth weather when the shore is clear of ice by “tracking” along the beach with men and dogs, one person at least always remaining on board to steer with a paddle at the stern.
