Stone Hammer—Spanish Flat.
The mortar shown in the cut was found in gravel at a depth of ten feet, at Shingle Springs in El Dorado County. At Georgetown and vicinity there were found at different dates, large stone dishes very similar to that at Gold Springs Gulch, shown in a preceding cut; grooved stones like those at Spanish Flat, soon to be mentioned; and mortars resembling that at Kincaid Flat. At Spanish Flat were found several oval stones with grooves round their circumference, as shown in the preceding cut, and weighing from a pound and a half to two pounds. They were apparently used as hammers or weapons by fitting a withe handle round them at the groove. Many other mortars and stone implements were taken from the same locality, including two pendants, shuttles, or bow-handles, very well worked from greenstone, five or six inches long, and about one inch thick in the middle. These two relics, together with a similar one from Table Mountain before alluded to, are shown in the cut. At Diamond Spring mortars were found at a depth of a hundred feet, and both fossil bones and stone relics have been taken from time to time from the mines about Placerville.[XII-21]
Stone Implements—Spanish Flat.
In Placer County, mastodon bones are reported at Rockland, and stone mortars and other implements at Gold Hill and Forest Hill. One dish at the latter place was much like that at Gold Springs Gulch, shown in a preceding cut.[XII-22]
In Nevada County stone implements have been found at different dates, from ten to eighty feet below the surface, at Grass Valley, Buckeye Hill, Myer's Ravine, Brush Creek, and Sweetland.[XII-23]
Fossil bones of extinct animals and stone implements like those that have been described, and which I do not deem it necessary to mention particularly, since such mention would be but a repetition of what has been said, with a list of depths and localities, have been found, according to Mr Voy's explorations, in Butte County at New York Flat, Oroville, Bidwell's Bar, and Cherokee Flat; in Stanislaus about Knights Ferry; in Amador at Volcano, Little Grass Valley, Jackson, Pokerville, Forest Home, and Fiddletown; in Siskiyou at Trench Bar, on Scott River, at Yreka, and Cottonwood; in Trinity about Douglas City; in Humboldt, at Ferndale and Humboldt Point; in Merced at Snelling on Dry Creek; in Mariposa, at Horse Shoe Bend, Hornitos, Princetown,—a mortar thirty-six inches in diameter—Buckeye Ravine, Indian Gulch, and Bear Creek; in Fresno at Buchanan Hollow and Millerton; and at several points not specified in Tulare and Fresno.[XII-24]
