The shoe (Fig. 483) is either tied or riveted to the runner. If tied, the lashing passes through sunken drill holes to avoid any friction in moving over the snow. The right and left sides of a whale’s jaw are frequently used for shoes, as they are of the proper size and permit the shoe to be of a single piece. Ivory is cut into flat pieces and riveted to the runner with long treenails. The points are frequently covered with bone on both the lower and upper sides, as they are easily injured by striking hard against hummocks or snowdrifts. Sometimes whalebone is used for the shoes.
The cross bars (napun) project over the runners on each side and have notches which form a kind of neck. These necks serve to fasten the thongs when a load is lashed on the sledge. The bars are fastened to the runners by thongs which pass through two pairs of holes in the bars and through corresponding ones in the runners. If these fastenings should become loose, they are tightened by winding a small thong round them and thus drawing the opposite parts of the thong tightly together. If this proves insufficient, a small wedge is driven between the thong and the runner.

The antlers attached to the back of the sledge have the branches removed and the points slanted so as to fit to the runners. Only the brow antlers are left, the right one being cut down to about three inches in length, the left one to one and a half inches. This back forms a very convenient handle for steering the sledge past hummocks or rocks, for drawing it back when the points have struck a snowdrift, &c. Besides, the lashing for holding the load is tied to the right brow antler and the snow knife and the harpoon line are hung upon it.
