Book excerpt: Excerpt from Contributions to Economic Geology, 1908, Vol. 1: Metals and Nonmetals, Except Fuels The first two bulletins of this series included numerous papers relating to the economic geology of Alaska. In View of the rapid increase of economic work, both in Alaska and in the States, and the organization of a division of Alaskan mineral resources distinct from the division of geology, it was in 1905 considered advisable to exclude all papers relating to Alaska. These were brought together in a separate volume entitled Report of progress of investigations of mineral resources of Alaska in Bulletin 259. A similar segregation of papers relating to Alaska. Has since been made and published annually. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Contributions to Economic Geology, 1908, Vol. 2: Part II. Mineral Fuels The first or dominant factor was the determination of the character and the valuation of the public land. These determinations were made wholly for the use of the Government itself in disposing of its mineral land. The second or general investigation of the mineral resources of the country was made for the benefit of the public at large and the results of this work are embraced in the series of reports of which this volume is one. The order in which the fields are exam ined depends entirely on the needs of the Government in disposing of its land now on the market, but in general the more important fields in the public-land States have been examined first. The work has been done under the general direction of the writer, who has been most ably assisted in the coal work by Cassius A. Fisher and all the men engaged in the work. It is impossible to enumerate the services performed by each man, but the success of the work has been due to the individual efforts of every member of the force and also to the hearty cooperative or team work without which it would have been impossible to carry on the work successfully. Although economic questions had to be given prominence, the writer wishes to congratulate each geologist on the amount of scientific data which have been accumulated and on the permanent value of the results and their bearing on the vexed question of the stratig raphy of the American Mesozoic and Tertiary rocks. The writer desires particularly to acknowledge his indebtedness to T. W. Stanton and F. H. Knowlton, who have so ably assisted in field and office in collecting and interpreting the fossils associated with the coal beds. This work has been invaluable, for without it the tangled problems of correlation and stratigraphy could not have been solved. For forty years the age of the coal-bearing rocks of the Rocky Mountain States has been in dispute, and while it can not be claimed that the question is settled, still the Survey's systematic examination of the coal fields during the last three years, in connection with the classification of the lands, has gradually brought order out of chaos. Now the end seems to be nearly in sight, and it is confidently believed that a few years' work will completely solve this perplexing problem.

Book excerpt: Excerpt from Advance Chapter From Contributions to Economic Geology, Vol. 1: Short Papers and Preliminary Reports, 1909 There is also a common division of the district into two parts, one east of Sacramento River and -one west. This division. Is useful for purposes of geographic description, but although there are certain differences in the deposits characteristic of opposite sides of the Sac ramento, this distinction is often exaggerated. Redding, the county seat and the principal town of the region, with a population of about is the chief distributing point for the mines. It is about 10 miles southeast of the west end of the crescent and 20 miles southwest of the east end. Other important settlements have sprung up near the chief mines and smelters; among these are Keswick (now largely deserted), Coram, Kennett, Copper City, Winthrop, and Ingot. The Portland branch of the Southern Pacific Railroad crosses the western part of the region and provides outlet for the smelting towns of Keswick, Coram, and Kennett, and indirectly for the mines on the west side of the Sacramento. Two companies, the Mountain and the Mammoth, have built private rail road lines connecting their mines with their smelting plants, located respectively at Keswick and Kennett; one of these, the Mammoth, and one other, the Balaklala (which also transports for the Trinity Company), connect mine and smelter with aerial tramways. The Bully Hill and Afterthought districts have been served by the Anderson and Bellavista Railroad, 8. Private branch from the Southern Pacific which terminates at Bellavista, from which these districts are, respectively, 15 and 12 miles distant. The Sacramento Valley and Eastern Railroad, recently completed, now gives to the mines and smelter of the Bully Hill district direct connection with the Southern Pacific; and the principal company in the Afterthought camp, it is understood, hopes soon to extend the Anderson and Bellavista line to its property. The heavy precipitation of the rainy season of winter and early spring acts as a serious impediment to the mines dependent on wagon transportation, but in other respects the climate is on the whole favor able to efficient operation, the temperature being moderate and snow falls light and of short duration. Abundant power is available from the streams and has been utilized to a considerable extent, through the medium of electricity, for mining operations and for other purposes. Timber for building and for use in the mines is still plentiful in the surrounding neighborhood. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
