Fig. 345a represents the model (No. 56563 [225] from Utkiavwĭñ), which gives a very good idea of the shape of one of these boats. It is quite correct in all its parts, though the timbers are rather too heavy, and there are not so many ribs and floor timbers as in a full-sized canoe. The breadth of beam, 6.2 inches, is at least 1 inch too great in proportion to the length, 25 inches. The cover is one piece of seal skin which has been partially tanned by the “white-tanning” process, and put on wet. In drying it has turned almost exactly the color of a genuine boat cover. The frame, as is often the case with a full-sized boat, is painted all over with red ocher. (See Fig. 345b, inside plan.)
Fig. 346.—Ivory bailer for umiak.
For bailing these boats a long narrow dipper of ivory or bone is used, of such a shape as to be especially well suited for working in between the floor timbers. Fig. 346 represents one of these (No. 56536 [40] from Utkiavwĭñ). It is a piece of walrus tusk 16.3 inches long. The cavity is 1.1 inches deep and was excavated by drilling vertical holes and cutting away the substance between them. Some of the holes have not been completely worked out. A similar bailer (No. 89835 [1010] also from Utkiavwĭñ) is made of reindeer antler, a substance much more easily worked than the ivory, as the soft interior tissue exposed by cutting the upper side flat is readily carved out. As with the walrus tusk, the natural curve of the material gives the proper inclination to the handle. It is 18.3 inches long.
When the umiak is fitted out for whaling a stout U-shaped crotch of ivory or bone, about 7 inches long and 5 wide, is lashed between the gunwales where they meet at the bow. In this the heavy harpoon rests when they are approaching a whale. It is only used when whaling. The Museum collection contains specimens of this sort from as far south as the Diomede Islands.
We brought home five specimens of these kû´nnɐ, of which No. 56510 [117] Fig. 347 has been selected as the type. This is made of two bilaterally symmetrical pieces of white walrus ivory, each piece consisting of one arm of the crotch and half the shank. Its total length is 7.8 inches. The two pieces are held together by a stout wooden tree-nail, and above this a lashing of sinew-braid, lodged in two deep vertical channels one on each side of the shank just below the arms, and wedged above and below on both sides with slips of wood. A hole is drilled through each side of the butt close to the end, and through these a lashing is stretched across the reentering angle of the butt consisting of four turns of sinew braid with the end closely wrapped round the parts between the holes, and neatly tucked in.
