Up to 1926 no archeological work had been done along the Yukon or its tributaries, and barring a few isolated specimens there were no archeological collections from these regions. The archeology of the river consists, (1) of the dead but formerly known villages; (2) of older sites, "dead" and unknown before even the Russians arrived; and (3) of random stone objects worked by man that now and then are washed out from the river banks or are found in working the ground. Except in details conditions are much alike along the whole river and will best be dealt with as a whole. THE RANDOM SPECIMENS Wherever the beach of the river shows more or less of stones that are not talus or just pebbles, there are generally found stones worked by man. Such localities are scarce. The first exists between Tanana (the village) and the mission above it. Here specimens are found occasionally on the beach and occasionally in the soil of the local gardens. Other such sites were located at Bonasila, below Anvik, and in four places between Paimute and the Russian Mission. A few are also present from Marshall seaward. An examination of the terrain adjacent to such parts of the beach shows mostly, but not always, traces of an old settlement. The specimens consist of characteristic axes or adzes, stone scrapers, hammers, stone knives (along the Eskimo part of the river), tomahawk heads (probably), objects less well defined, and chips. There may be semifossilized animal bones, and rarely a bit of charcoal, a piece of pottery (for details see Narrative), or an object of ivory. The ax proper is peculiar. It is a cupid's-bow ax, double-edged, and with one or two grooves across its middle. (Pl. 10.) It is as a rule made of heavy basaltic stone, and its edges are sharpened by polishing. Rough parts may have been polished also on the body. Its distal surface is convex (from sharp edge to sharp edge), its proximal surface straight or mildly convex. I succeeded in getting a specimen remounted recently by one of the Indians near Tanana. This form of an ax is still remembered by the old Indians when in use. They cut trees with it, cutting sidewise and detaching the wood in splinters. They also remember clubs with stone heads, and told me they were carried on the back over the right shoulder so as to be ready for instant and effective use.
