Seite 116 - The farms, lands, and other property of every description belonging to the Puget's Sound Agricultural Company, on the north side of the Columbia Eiver, shall be confirmed to the said Company. In case, however, the situation of those farms and lands should be considered by the United States to be of public and political importance, and the United States...
Seite 95 - ... to sea without risk of being overtaken. The other point demanding immediate attention was opening a sure and easy communication by land with the Atlantic States. The whole value of these* countries to the United States depends on this. The route by the isthmus is too expensive and too insufficient for the number of travellers. The steamers can bring with propriety not three hundred a month, while the emigration by land, if divided throughout the year, would average three thousand a month. The...
Seite xvii - The rivers, in forming. their channels, or breaking their way through the hills, have come in contact with the quartz containing the gold veins, and by constant attrition cut the gold into fine flakes and dust; and it is found among the sand and gravel of their beds at those places where the swiftness of the current reduces it, in the dry season, to the narrowest possible limits, and where a wide margin is consequently left on each side, over which the water rushes, during the wet season...
Seite 21 - ... basin was noticed by Mr. Tyson in 1849. He examined it with a view to ascertain whether a deposit of coal might not exist below the surface; and also whether its structure would indicate the means of supplying water for agricultural and mechanical purposes. In regard to the first question he says: ''The first query is answered by the fact of finding the comparatively recent strata of a formation, not older than the eocene and miocene periods, resting immediately on the metamorphic or hypogene...
Seite xvii - ... penetrating to a great depth, is quartz ; this, however, does not cover the entire face of the country, but extends in large bodies in various directions — is found in masses and small fragments on the surface, and seen along the ravines and in the mountains overhanging the rivers, and in the hill sides in its original beds.
Seite xvii - These veins do not present the appearance of places where gold may have been lodged by some violent eruption. It is combined with the quartz in all imaginable forms and degrees of richness. The rivers present very striking, and it would seem conclusive evidence respecting the quantity...
Seite 21 - We arrived upon the southeast bank of the Feather river, six miles below the junction of the Yuba, at 5 pm, at a point immediately opposite Sutler's " Hock farm" — here we encamped for the night. This is the most beautiful situation that I have seen in California. The river, which at this place is about six hundred yards in width, is lined on either bank with majestic sycamores, in afine grove of which, upon the west bank, is situated Captain...
Seite 21 - ... the coal formation, which belongs to the lower of the secondary series." A coal formation under the basin is therefore out of the question, unless deeply seated, and entirely covered, edges and all, by the sedimentary rocks above noticed. The character of the soil in many parts of this valley will render it of little importance as an agricultural district, unless water in ample quantities for irrigation can be obtained. (These remarks apply particularly to the upper terrace of the valley on each...
Seite xxxv - Territory, be printed, with the accompanying map ; and that two thousand five hundred , in addition to the usual number, be printed for the use of the Senate.
Seite 19 - Tyson,103 published in 1851. He appears to have believed that they were metamorphosed sediments of some sort. The following appears in his descriptions of the region around Bodega : The northwestern end of this small vale is abruptly terminated by steep acclivities, whose rocks mainly consist of several varieties of compact quartz such as chert, jasper, etc. There is every shade of white and gray to nearly black, as well as yellow, red, and brown, each color continuous in separate layers. It is evident...
