Book Description
Excerpt from Dredges and Gold Dredging We are often asked why we located in the East. Briefly, because we are right in the center of production of all the material entering into the construction of a dredge. The largest part of the machinery is of special steel, cast, wrought, manganese, chrome and nickel, all of which are produced only in the East and at our door; in fact, most of the material for all of the important parts of every dredge built in this country is produced on the Atlantic Coast. Being located in the very center of production, we procure the best material quickly and cheaply. Inspection And Selection Of Raw Material Our supervising engineers are constantly visiting the mills, inspecting, selecting and testing our materials; therefore, we get the best selection and quality to meet our wants in the shortest time possible. Hence we are able to turn out complete dredges in much shorter time, and at less cost, than any of the Western Manufacturers. We are the first and only concern in this country to devote its whole attention exclusively to the designing and building of gold dredges; therefore, we are especially well equipped to do this work much better and more quickly than other concerns; for with them, dredge building is only a side line, and their principal business, which receives their best efforts, is the manufacturing of some other lines of product. Some of our engineers were taken from the California dredging fields, and thus we have the advantage of the many lessons learned in that country.

Book Description
Excerpt from The Dredging of Gold Placers During the past two years the writer has contributed to English and American periodi cals 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.

Book Description
Excerpt from Prentice-Hall Tax Service for 1919 This allowance is not based upon the difference between the actual war cost of such facilities and what they would have cost at pre-war prices. Obviously the taxpayer is not entitled to recover or extinguish through amortization more than the difference between the war cost of such property and what he can sell the property for after the war, or if he continues to need and use it in his business, what it would have cost him after the war. As the rule is expressed in Article 183 of the Regulations: The total amount to be extinguished by amortization, in general, is the excess of the unextinguished or unrecovered cost of the property over its maximum value (either for sale or for use as part of the plant or equipment of a going business) under stable post war.

Book Description
It's the 1920s, and Bo was headed for an Alaska orphanage when she won the hearts of two tough gold miners who set out to raise her, enthusiastically helped by all the kind people of the nearby Eskimo village. Bo learns Eskimo along with English, helps in the cookshack, learns to polka, and rides along with Big Annie and her dog team. There's always some kind of excitement: Bo sees her first airplane, has a run-in with a bear, and meets a mysterious lost little boy. Bo at Ballard Creek by Kirkpatrick Hill is an unforgettable story of a little girl growing up in the exhilarating time after the big Alaska gold rushes.

Book Description
Excerpt from Gold Dredging Enumeration of these latter, howe\ er, may serve to mark the failures of inventors in the past, and thus warn their successors against similar attempts. Undei the heading of obsolete machines may be classed the pneumatic caisson, the submarine boat, the hydraulic. Elevator, and the vacuum dredge. The pneumatic caisson was on the principle employed in making cylinders for the piers of bridges. In it, the diver was let down so as to work direct on the bed of the river. This might be all right for a rich patch, the situation Of which was exactly known; but, for men-day work, where much barren stuff had to be lifted, it proved a lamentable failure. Submarine boat, on the principle of the diiing bell, is said to ha\e been con structed, but never used. Dredging operations using the principle of the hydraulic elevator were attempted on the Chestatee River, Lumpkin co., (ia., but proved unsuccessful, the elevator being out of place in a river bed, many feet below the lewl Of the water, Since most of its work consisted in raising water that did not contain gold. The Bazin dredge was one of the first worked on the vacuum system. The principle upon which the vacuum in this machine was obtained lay in the difference of level between the water outside and the bottom of the bull, in consequence of which the water was forced up the suction-pipe projecting down from the hull to the river bed, and in doing SO carried up the auriferous sands. A centrifugal pump re ceived all the matter forced into the tube, and, adding fresh impulse to its progress, delivered it to the washing appliances. A disad vantage Of this form of dredge was that it required a considerable depth of water in order to produce the requisite amount of vacuum for efficient work. This defect led to the introduction of steam vacuum dredges. The boat was fitted with a boiler and steam pump, 0, each connected with a vacuum chamber, from which projected the.
