Seite 154 - We may then conclude that that part of the average mollusk fauna which is capable of leaving traces in the shape of fossils, under conditions not greatly differing from those of the present day, if situated in the arctic or boreal region, would comprise about 250 species; in the cool temperate region about 400 species; in the warm temperate, about 500 species; and in the tropical region, not less than 600 species.

Seite 149 - Greece ranch house, about four miles east of Vader, Washington. There appear to be two formations represented at this point. The fossils occur in a sandstone formation which is associated with a conglomerate. The upper zone which is mostly Ostrea is in a conglomerate composed of basalt pebbles and boulders. The lower zone is nearly all small gastropods which occur in blue sandstone. These two beds dip northwest at a very small angle — about 0°-5°.

Seite 48 - The Tejon is found most extensively developed in the vicinity of Fort Tejon and about Martinez. From the latter locality it forms an almost continuous belt in the Coast Ranges to Marsh's, 15 miles east of Mt. Diablo, where it sinks under the San Joaquin plain. It has also been found in the same range as far south as New Idria and as far north as near Round Valley, Mendocino County."12 The most southerly Tejon in California known today is found at Pt.

"Shell subtrigonal, cuneate ; beaks anterior, with the cardinal margin sloping convexly to the posterior end, which is narrow ; anterior end prominent above, and curving inwards rapidly below towards the base ; lunule small, very narrow, acute below and impressed.
Seite 149 - A few yards to south a well-stratified coarse gray compact sandstone is exposed dipping south at angle of 10° and striking N. 70° E. This sandstone is probably Eocene. About 20 feet south of fossil beds a mass of coarse conglomerate is butting perpendicularly against sand to the south. This conglomerate appears to be same as that where the fossils occur.
Seite 20 - Cape, and in fact the whole country, excepting the tops of the mountains at Clyoquot. The water on its rise became very warm, and as it came up to the houses, those who had canoes put their effects into them, and floated off with the current, which set very strongly to the north. Some drifted one way, some another ; and when the waters assumed their accustomed level, a portion of the tribe found themselves beyond Nootka, where their descendants now reside, and are known by the same name as the Makahs...
