I obtained one pair of syenite disk labrets, No. 56716 [197] (figured in Point Barrow Rept., Ethnology, Pl. V, Fig. 2). Each is a flat circular disk (1.7 and 1.6 inches in diameter, respectively) of rather coarse-grained black and white syenite, ground very smooth, but not polished. On the back of each is an elliptical stud, like that of a sleeve-button, 1.2 and 1.1 inches long and 0.8 and 0.6 broad, respectively. [Illustration: FIG. 93.--Blue and white labret from Anderson River.] Fig. 93, No. 2083, is one of the blue and white disks said to come from the Anderson River. This is introduced to represent those worn at Point Barrow, which are of precisely the same pattern. The disk is of white marble, 1½ inches in diameter, and in the center of it is cemented, apparently with oil dregs, half of a transparent blue glass bead, three-quarters of an inch in diameter, around the middle of which is cut a shallow groove. Similar marble disks without the bead are sometimes worn. These blue and white labrets appear to be worn from Cape Bathurst to the Kaniag peninsula, including the Diomede Islands (see figure on p. 140 of Dall’s Alaska). There are specimens in the Museum from the Anderson River and from the north shore of Norton Sound and we saw them worn by the Nunatañmiun, as well as the natives of Point Barrow and Wainwright Inlet. The beads, which are larger than those sold by the American traders, were undoubtedly obtained from Siberia, as Kotzebue, in 1816, found the people of the sound which bears his name wearing labrets “ornamented with blue glass beads.”[N262] The high value set on these blue-bead labrets has been mentioned by Franklin[N263] and T. Simpson,[N264] as well as by Dr. Simpson.[N265] The last named seems to be the first to recognize that the disks were made of marble. All previous writers speak of them as made of walrus ivory. [Footnote N262: Voyage, vol. 1, p. 210. Labrets of precisely the same pattern as the one described are figured in the frontispiece of this volume. (See also Choris, Voyage Pittoresque).] [Footnote N263: 2d Exp., p. 118.] [Footnote N264: Narrative, p. 119.] [Footnote N265: Op. cit., p. 239.] There are still at Point Barrow a few labrets of a very ancient pattern, such as are said to have been worn in the middle of the lip. These are very rarely put on, but are often carried by the owners on the belt as amulets. All that we saw were of light green translucent jade, highly polished. I obtained one specimen, No. 89705 [866] (figured in Point Barrow Rept., Ethnology, Pl. V, Fig. 1), a thin oblong disk of light green, translucent, polished jade, 2.6 inches long, 1.1 wide in the middle, and 0.8 wide at the ends, with the outer face slightly convex. On the back is an oblong stud with rounded ends, slightly curved to fit the gums.
