Excerpt from Placer Mining for Gold in California The increase in the price of gold from in 1932 to in 1933 and to in 1934 made such stories seem even more plausible and helped further to stimulate the migration of men to the creeks, despite the unfortunate experiences related by most of those drifting back from the gold-bearing areas. Stories of those who succeeded in making a living and of the very few who made strikes continued to be magnified out of all proportion, both in passing from mouth to mouth and in the press, and brought new recruits to the streams as late as 1937. It is obvious to those versed in gold mining that the facts are greatly exaggerated in these stories. To the hard-pressed unemployed, however, these accounts sounded like the answer to their need. How could they know that for every one who made a strike in placer mining, tens of thousands would find little or nothing, that not more than a few score at most could possibly expect to develop a profitable lode mine, and that large amounts of capital would be required for most of these mines? The experience of the thousands who are unsuccessful in placer ing does not make news; the story of the man here and there who is lucky does. Most of the accounts were stories of success, stories which were news but which were misleading to the unemployed.

Excerpt from Gold Mines and Mining in California: A New Gold Era Dawning on the State; Progress and Improvements Made in the Business; Perfected Methods, Processes and Machinery As remarked in the prospectus issued by the publishers of this book, we have at length so perfected the business of gold mining in California. Both as regards the methods, machinery and processes in use, that material of very low grade, whether quartz or gravel, can be handled with profit. Latterly very few failures have occurred in this business; fewer, perhaps, than in any other of our leading industries, nor are many likely to occur hereafter. As new conducted, it is, in fact, fully as safe as farming. Manufacturing, or merchandising, paying, at the same time far better than any of these.

Excerpt from Hittel on Gold Mines: And Mining of California In quartz mining the auriferous rock is ground to a very fine powder, the gold in which is caught in quicksilver, or on the rough surface of a blanket, over which the fine material is borne by a stream of water. About two-thirds of our gold is obtained from the placers, and one-third from the quartz. A mine is defined and generally understood to mean "a subterraneous work or excavation for obtaining metals, metallic ores or mineral substances;" but this definition does not apply to our placer mines, which are places where gold is taken from diluvial or alluvial deposits. Most of the work is not subterraneous; it is done in the full light of day. In some of the claims the pay-dirt lies within two feet of the surface; in others it lies much deeper, but all the superincumbent matter is swept away. Water is the great agent of the placer miner; it is the element of his power jits amount is the measure of his work, and its cost is the measure of his profit. With an abundance of water he can wash every thing; without water he can do little or nothing. Placer mining is almost entirely mechanical, and of such a kind that no accuracy of workmanship or scientific or literary education is necessary to mastery in it. Amalgamation is a chemical process it is true, but it is so simple that after a few days experience, the rudest laborer will manage it as well as the most thorough chemist. It is impossible to ascertain the amount of gold which has been taken from the mines of California. Records have been kept of the sums manifested at the San Francisco Custom House, for exportation, and deposited for coinage in the mints of the United States; and there is also some knowledge of the amounts sent in bars and dust to England; but we have no account of the sums carried by passengers to foreign countries and coined elsewhere than at London, or used as jewelry, or of the amount now in circulation in this state. According to the books of the Custom House of San Francisco, the sums manifested for export were as follows: In 1849, $4,921,250; in 1850, $27,676,346; in 1851, $42,582,695; in 1852, $46,586,134; in 1853, $57,331,034; in 1854, $51,328,653; in 1855, $45,182,631; in 1856, $48,887,543; in 1857, $48,976,697; in 1858, $47,548,025; in 1859, $47,640,462; in 1860, $42,303,345; in 1861, $40,639,089; a total of $551,603,904 in twelve years. The exportation of gold commenced in 1848, but we have no record of the sums sent away in that year. Previous to 1854 very large sums were carried away by passengers, who gave no statement at the Custom House; since that year, the manifests show the exportation correctly within a few, millions. I am entirely satisfied that the total gold yield of California has been not less than seven hundred millions of dollars; but I have not room here to state the reasons for this opinion.

Excerpt from California Mines and Minerals The subject matter of this work is confined as far as possible to a plain statement of facts, regarding our great state and its mineral wealth. It has been a difficult and laborious task to gather all the data and statistics, as aside from a few counties, whose citizens were public spirited enough to look after their county interests, all matter has been prepared from the Secretary's office. In the early stages of the labor, much assistance was promised by members of the Association and others, in the form of special articles upon subjects of great interest to the industry, as well as reports upon various counties and their resources. As the work progressed, however, it was found that many substitute articles would be necessary, as promises make poor reading matter. The Association is indebted to the contributors, whose articles upon various subjects will be found highly interesting and instructive; to the advertisers, whose solid financial support has materially assisted in defraying the cost of publication; to Mr. J. O. Denny, whose able and conscientious services have been indispensable in the editorial work, and to the publishing house, for the extra care and attention given to the general make-up.

Mining historian Kerby Jackson introduces us to a classic mining work in this important re-issue of "Gold Dredging in California." Unavailable since 1905, this publication was originally compiled by the California Bureau of Mines. A century and more ago, giant dredging machines dug in California's rivers and creeks in search of illusive golden riches. First appearing in the 1850's, gold dredges finally reached their peak of development in Siberia and New Zealand before becoming popular again in the United States. This book offers a unique historical perspective on the gold dredges that once operated in California. This book on California mining history is lavishly illustrated with dozens of rare historic photos gold dredges that once operated in California, as well as hard to locate plans on how these dredges were designed. Note: This edition is a perfect facsimile of the original edition and is not set in a modern typeface. As such, some type characters and images might suffer from slight imperfections or minor shadows in the page background.

Excerpt from The Dredging of Gold Placers During the past two years the writer has contributed to English and American periodicals several articles, dealing with the phase of mining to which the following pages are devoted. Some interest appears to have been aroused among both mining men and the lay public by these articles, and the wish has often been expressed that they should be incorporated in one volume. This book is an attempt to meet that desire. The industry is a comparatively new one, and the views of dredging men in regard to many questions, both of construction and design, are still in a state of flux. This book is offered to the world, therefore, not by any means as a technical work, but in the sincere hope that it will help and interest company directors, property managers, prospectors, and those of the investing public who have acquired, or think of acquiring, a share interest in a gold-dredging concern.
