"Decorative attempts consist of bold incised parallel transverse lines on the upper sector of the outer surface of the vessel. Deep corrugations appear on the inside of the rim flare. Both corrugations and incised line decorations were made with a paddle or wood splinter shaped for the purpose. Some of the shards have deeply incised punctations irregularly encircling the outer surface of the vessel just below the rim extension. "Shallow spherical pottery lamps accompanied surface burials at Bonasila. These lamps have a less durable tempering material than the other pottery fragments recovered. The paste is porous and is poorly fired. Decorative designs incised on the interior surface of the lamps are reminiscent of typical Eskimo punctate designs as traced on the inner circumference of rectilinear or curvilinear etchings on ivory and bone. It is very probable that these pottery lamps are of a later date and are of Eskimoan handicraft. THE ALASKAN GROOVED STONE AX [Pl. 10] "The grooved stone ax is a typical New World implement. Its distribution is limited to tribes of the eastern maize area, the Pueblo tribes of the Southwest, the Athapascans, and the northern woodlands tribes. Elsewhere in America grooved stone implements of any description are rare, although not unknown. The groove for the attachment of cord or sinew binding is common also to the stone adze, which is characteristic of Indian tribes of the Pacific Northwest and of the Eskimo of Arctic America. The distribution of the stone adze is more intensive but is much less extensive than is that of the grooved stone ax and appears to be an environmental form borrowed from the Arctic tribes by the Indian of southeast Alaska and of British Columbia. "The double-bitted, multiple-grooved stone ax has two areas of distribution in North America. One of these is the country of the northeastern woodlands Indians, extending as far south as the Central Atlantic States. The other area of distribution is the extreme northwest, or the mainland of Alaska. "In the collection brought to the National Museum from Alaska by Doctor Hrdlička are eight grooved stone implements. All but one of these have cutting edges for use as axes or adzes. The exception, Cat. No. 332809, U.S.N.M., is a grooved spherical stone maul or club 9.5 centimeters (3.7 inches) long and 7.5 centimeters (2.9 inches) in sectional diameter. This grooved object was found near Tanana on the beach of the Yukon River. Like the grooved stone axes in Doctor Hrdlička's collection, the groove is incomplete. A flattened space of approximately 2 centimeters is left un-grooved for the hafting of a flat surfaced handle end with binding, which is passed around the transverse groove and then through a hole in the wooden handle.
