Page 141 - A very large amount of the hardened asphaltuin, mixed with sand and the bones of cattle and birds, which have become entangled in it, lies scattered over the plain. Before 1860 the experiment of shipping it to San Francisco for the purpose of distilling burning oil from it had been tried, without success, at least in a pecuniary point of view.

Page 89 - Nos. 12 to 15 Inclusive, it is to be inferred that several others have been in existence in earlier days. Indeed, one or two of these old wells still contain a slight amount of oil. The producing wells are sunk in northward-dipping sandstone and shale a mile north of the axis of the Tapo anticline. They yield at present from 5 to 40 barrels of oil per day. The gravity is 20° to 24° Baume, the 20° oil being produced by the well highest up in the canyon and lowest as to the strata penetrated.
Page 267 - The classes numbered 2, 7, and 8 are sold at cost of publication; the others are distributed free. A circular giving complete lists can be had on application. Most of the above publications can be obtained or consulted in the following ways: 1. A limited number are delivered to the Director of the Survey, from whom they can be obtained, free of charge (except classes 2, 7, and 8), on application. 2. A certain number are delivered to Senators and Representatives in Congress for distribution. 3. Other...
Page 89 - The whole of the lower half of the Vaqueros strata exposed in Tapo Canyon shows a greater or less impregnation with petroleum. No unusual amount appears to have been assembled in proximity to the axis of the main anticline, and it may be that the productive territory is a particularly rich portion of the series of beds which, from some cause or other, has held its oil better than the great mass of the beds in the region. From the surface no reason can be seen for the enrichment of one portion of...
Page 139 - ... One of the springs was passed on our way to the city, and was near the outcrop of bituminous shale in the banks of the creek already described. This spring was nothing more than an overflow of the bitumen from a small aperture in the ground, around which it has spread on all sides, so that it covers a circular space about 30 feet in diameter. The accumulated bitumen had hardened by exposure and its outer portions were mingled with sand, so that it was not easy to determine its precise limits....
