The specimens figured show the different styles of ornamentation, which always consist of incised patterns colored with red ocher or rarely with soot. These never represent natural objects, but are always conventional patterns, generally a single or double border on two or more faces with short oblique cross-lines and branches. Harpoon heads at Point Barrow are probably never ornamented with the “circles and dots,” so common on other implements and on the harpoons of the southern Eskimo. [Illustration: FIG. 217.--Typical walrus-harpoon heads. 1/2] Twenty-eight of the heads still have the leaders attached to them. The object of this short line is to enable the hunter to readily detach a broken head and put on a fresh one without going to the trouble of undoing a splice, which must be made strong to keep the head from separating from the line. It is made of a stout piece of rawhide thong, the skin of the walrus or bearded seal, about one-third inch in diameter, and usually from 2 to 3 feet long. It is always passed through the line hole, as in the specimen described, and the ends are made into a becket for attaching the line, with an end left to serve as a handle for pulling the two beckets apart when the main line ends in a becket. Occasionally (two are made this way) the longer end is simply doubled in a bight, and the three parts are then seized together with sinew braid, but it is generally made with a splice, the details of which differ slightly on the different leaders.
