_Drills and borers._--The use of the bow drill appears to be universal among the Eskimo. Those at present employed at Point Barrow do not differ from the large series collected at the Mackenzie and Anderson rivers by MacFarlane. The drill is a slender rod of steel worked to a drill point and imbedded in a stout wooden shaft, which is tapered to a rounded tip. This fits into a stone socket imbedded in a wooden block, which is held between the teeth, so that the point of the drill can be pressed down against the object to be drilled by the head, leaving both hands free to work the short bow, which has a loose string of thong long enough to make one turn round the shaft. The collection contains ten of these modern steel or iron drills, fifteen bows, and seven mouthpieces. No. 89502 [853], figured in Point Barrow Rept., Ethnology, Pl. II, Fig. 1, has been selected as a typical drill (niă´ktun). The drill is a cylindrical rod of steel beaten out into a small lanceolate point, which is filed sharp on the edges. The shaft is made of hard wood. The remaining drills are of essentially the same pattern, varying in total length from about 11 inches to 16½. Fig. 149, No. 89499 [968] shows a somewhat unusual shape of shaft. The lashings round the large end are to keep it from splitting any more than it has done already. The drill is of iron and the shaft of spruce, which was once painted with red ocher. [Illustration: FIG. 149.--Bow drill. 1/3] [Illustration: FIG. 150.--Bow drill and mouthpiece. 1/4] No. 89497 [819] (Fig. 150) has a ferrule of coarse-grained bone neatly pegged on with two small pegs of the same material. This is unusual with steel drills. The shaft is of spruce and of the same shape as in the preceding specimen. No. 89595 [875] (Fig. 151) is figured to show the way in which the shaft has been mended. A wedge-shaped piece 3½ inches long and 0.3 to 0.4 inch wide has been split out of the large end and replaced by a fresh piece of wood neatly fitted in and secured by two tight whippings of sinew braid, each in a deep groove. No. 89515 [861], figured in Point Barrow Report, Ethnology, Pl. II, Fig. 2, is a typical bow (pizĭksuá) for use with these drills. It is of walrus ivory, 16 inches long and oval in section. Through each end is drilled a transverse hole. A string of seal thong 21 inches long is looped into one of these holes by passing one end of the thong through the hole, cutting a slit in it, and passing the other end through this. The other end is passed through the other hole and knotted at the tip.
