Book Description
Excerpt from Quicksilver Resources of California: With a Section on Metallurgy and Ore-Dressing The important uses of quicksilver are the recovery of gold and silver from ores by amalgamation, the manufacture of fulminate for explosive caps, of electrical appliances and scientific apparatus, and in the preparation of drugs, vermilion, and an anti-fouling paint for ships' bottoms. Another interesting use to which quicksilver is also put, though in which it is not 'consumed, ' is as a floating bearing for the re volving lenses of lighthouses. About 600 pounds of quicksilver are required (depending on the size of the light) - being placed in a ciren lar groove or channel. The lens or lighting unit is set on a pontoon which. In turn, rests and revolves on the mercury. As the metal is not consumed, the loss after installation is insignificant. By far the great est consumption of quicksilver is in the manufacture of fulminate and of drugs. The increased adoption of the cyanide process in place of amalgamation in the treatment of gold and silver ores has materially decreased that demand for quicksilver of recent years, particularly in the western United States and in Mexico. The newest use for quick silver is the introduction of a small amount into the cylinders of steam turbines to improve the vapor pressure and thus increase efficiency.

Book Description
Excerpt from The Quicksilver Resources of California Gentlemen: I have the honor to transmit the results of the recent work of the State Mining Bureau in investigating the Quicksilver Resources of California, and which are embodied in Bulletin No. 27. This is the third of a series of bulletins, issued under my direction, on special features of the mining industry in California, and in which will be found a description of the geology of all the deposits of economic importance in the State, together with maps and such data as it was possible to obtain. The geological field work for this bulletin was performed by Mr. William Forstner, Assistant in the Field, of the State Mining Bureau. No description of any mine or prospect, nor of the geology of any part of the territory, has been given except after personal investigation by Mr. Forstner. In treating of the geology and the genesis of ore deposition, subjects of which differences of opinion exist, endeavors have been made to present as briefly and clearly as possible the different opinions, and some suggestions have been added which have resulted from Mr. Forstner's personal observation. In the chapter on the metallurgy of quicksilver, it has been the aim more to give the general principles upon which the different methods of treatment are based than to make a mere detailed description of the different installations.

Book Description
Excerpt from Geology and Mineral Resources of the Neenach Quadrangle, California Sir: I have the honor to transmit herewith Bulletin 153, Geology and Mineral Resources of the Neenach Quadrangle, California, prepared under the direction of Olaf P. Jenkins, Chief of the Division of Mines, Department of Natural Resources. The report is accompanied by a number of maps, charts, and illustrations, including a detailed geologic map, lithographed in color, of the 15-minute Neenach quadrangle. The area of this quadrangle is nearly 250 square miles, covering portions of the Tehachapi Mountains and Antelope Valley in Kern and Los Angeles Counties. Two famous earthquake fault zones, the San Andreas and Garlock faults, pass through the area mapped. Their junction point lies several miles to the west at Gorman and Lebec where State Highway 99 cuts through the Tejon Pass. It is significant that the area mapped contains tin deposits discovered and prospected during World War I. These, together with gold, copper, tungsten, molybdenum, marble and limestone, crushed rock, volcanic ash and ground water, are described in this bulletin. The author, John H. Wiese, prepared the report while in the employ of the United States Geological Survey and in connection with graduate study at the University of California at Los Angeles. Cooperating with the Federal Survey and the State University, the State Division has helped to sponsor the undertaking and is publishing the results of the work as one of its series of bulletins.

Book Description
Excerpt from Reminiscences of the Early Anthracite-Iron Industry, Vol. 29: An Address Delivered Before the American Institute of Mining Engineers, at the California Meeting, September, 1899 The specimen of anthracite coal which I hold in my hand, insignificant as it may appear to the casual observer, speaks volumes to me and to the initiated, as it suggests and represents the entire evolution of the use of anthracite coal in the manufacture of pig-iron, the growth and development of which it is my purpose to review here to-day. During our recent visit to the Mountain Copper Co.'s works at Keswick, I picked up this piece of coal from a pile of anthracite lying in the yard, asked Mr. Edwards, the manager, a countryman of mine, where it came from, and, to my surprise and delight, discovered that it had been brought all the way from Wales, and had come out of the identical vein which my father opened near Yniscedwin, about eighty years ago. I had no idea, before this incident, of contributing to the already full and complete programme of the day; but, being requested by our distinguished President and Secretary to do so, I consented to relate here the story which this remarkable find naturally brought back to my mind. David Thomas, my revered father, called by his Welsh countrymen "the pioneer of the anthracite iron-trade in America," was one of the principal actors in the history of manufacturing pig-iron with anthracite coal. I shall give here my personal recollections of his early experiments, trials, and final successes, as frequently related by him to me, together with quotations from a biographical sketch by E. Roberts, found in the number for October, 188-3, of the "Red Dragon," the national magazine of Wales. Mr. Roberts's narrative is authentic, by reason of his free access to the records of the Yniscedwin anthracite iron-works during his long connection with them.

Book Description
Excerpt from Hittel on Gold Mines: And Mining of California Chief Industry. -m1uing is the chief industry, of California. It employs more men and pays larger average wages than other branch of physical labor. Although it has been gradu decreasing in the amount of its production, in the profits to individuals engaged in it, and in its relative importance in the business of the state, it is yet and will long continue to be the largest source of our wealth, and the basis to support the other kinds of occupation.
