At Forest Hill, Placer County, the Darda- nelles mine, extensively worked in the earh' days b}- Richard Clark and others, has undermined and obliterated a half or more of a terraced spur or ''flat,'' as such features are called in that country, formerly occupied by an Indian village. (See plate XII.) According to Mr. Clark, who still resides in Forest Hill, this site has not been occupied by the natives since work began in the mine in 1852, but an hour's search l^rought to light a dozen mortars and grinding stones, twenty or thirty rubbing stones and pestles, together with several varieties of smaller tools. As the ground of the site sloped toward the mine, most of the larger and especially the rounder objects must long since have rolled into the great pit (fig. 1), the gravel walls of which are on the one side upward.

Many of the objects obtained by me were already in the gullies leading down to the mine, and in the pre- ceding half century large numbers must have gone over to become intermingled with the gravels, where they would remain for good, unless some observant miner happened to bring them to light. Speci- mens thus found, falling into the hands of such collectors as C. D. Voy, would naturally be added to the growing list
