Book excerpt: Excerpt from California Journal of Mines and Geology, 1947, Vol. 43 As a part of the United States Geological Survey 's wartime strategic mineral investigations the writers mapped the surface geology and acces sible workings Of the area during four days In January 1943, in order to determine the outlook for increased quicksilver production. Because no time was available for detailed laboratory study Of the ores or thin sec tions of the rocks, the principal contributions Of the work are the geologic maps included with this report.

Redding is 30 miles southeast by road, 18 miles of which is State highway; the balance Is the old Tom Green stage road, climbing the mountain on fairly steep grades above French Gulch. Carter states that this mine has produced or more from veins of ochre and quartz associated with the contact of the diorite porphyry and Bragdon slate. In some places the veins cut through both of the formations mentioned. This production was made in 1913 and earlier, with hand tools, and the treatment was in arrastras. Widths varied from a few inches to a maximum 'of 8 an average of about 2 ft. These workings have Since caved. Only assessment work was done for many years, but recently Carter has been working steadily in a lower tunnel.

This book was released on 2018-09-08 with total page 854 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from California Journal of Mines and Geology, Vol. 47: January 1951 Napoleon was the father of the beet sugar industry. During the Napoleonic Wars, France was cut off from the West Indian cane sugar by the English blockade. France utilized sugar beets and beet sugar made its first general appearance in the' 'corner grocery store.' 'prior to this time (1812) beet sugar had been little more than a laboratory curiosity since its discovery in 1747 by the German chemist, Andreas Margraf. Some evidence has recently been uncovered by H. W. Dahlberg indicating that the Spanish Padres knew that California Indians made sugar and syrup from wild sugar beets in the Santa Clara valley before 1775. Although the first United States beet sugar factory was not built in California, one of the first was erected by a coppersmith named Belper in-1856 at Ocean View, now part of the city of San Francisco. These early factories were not successful, however, and the second California factory became the first successful beet sugar factory in the United States. It was built by E. H. Dyer at Alvarado, Alameda County, and operated from 1870 through 1873. It was then moved to Soquel, Santa Cruz County, but ceased operations in 1880.

The others represent confidential reports of private individuals or of geological departments of oil companies and other commercial concerns. The numerous contributors have been exceedingly generous. If some have been omitted from this list it is either because of the desire of the contributor or an oversight on the part of the writer. It is the writer's desire, however, that this list of sources be made as complete as possible. Needless to say, the state geologic map would not have attained its present approach to completion if unpublished maps had not been so generously given to the undertaking.

Book excerpt: Excerpt from California Journal of Mines and Geology, Vol. 51: January 1955 Much of the physical aspect of our society has been made possible through the process of arc welding. The joining of heavy plates and large girders once was entirely dependent upon the use of a large num ber of rivets or bolts. Riveted seams of tanks and pressure vessels had to be calked, a laborious and not always effective procedure. Arc weld ing revolutionized much of engineering practice and many processes of industrial construction, and the modern achievements of arc welding stem largely from the development of coatings for welding electrodes.

This book was released on 2018-10-03 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from California Journal of Mines and Geology, 1952, Vol. 48 The increased use of the lead storage battery almost exactly parallels the growth of the automotive industry. A small proportion of lead stor age batteries - about 9 percent of the total lead tonnage used per year is used for purposes not connected With the automobile, such as in farm lighting installations, standby electric power stations, electric locomo tives, submarine service and others. Some of the non-automobile bat teries are the niekel-iron type1 and others are the niekel-cadmium types? Very few passenger cars, trucks, buses, tractors or other conveyances, however, make use of anything except the lead storage battery for start ing, lighting and ignition purposes. It is logical, therefore, to observe the growth of the lead storage battery industry by reference to the sta tistics of the automobile industry. Fortunately for this purpose, very accurate records exist of the automobile industry since its inception about 1895; from about 1910 to the present time, it can be assumed that each motor vehicle contained one lead storage battery. Ninety-one percent of all battery lead used annually is used in the automotive type of battery. Table 4 indicates the relative importance of the battery industry in various sections of the state. Battery manu facturers are concentrated in the Los Angeles and San Francisco Bay areas; battery production by counties is as follows in the order of im portance: Los Angeles, Alameda, San Francisco, Orange, San Bernar dino, San Diego, Sacramento and Kern.

Book excerpt: Excerpt from California Journal of Mines and Geology, Vol. 35: Quarterly Chapter of State Mineralogist's Report XXXV; January 1939 The accompanying report has been prepared from data and Information gathered by the authors, who were assisted by field workers Of a wpa project which was sponsored by the board Of supervisors Of San Diego County. For twelve months during 1936 and 1937 they inspected and reported on 325 mining claims and quarries in the county. The information thus Obtained was entered on questionnaires which had been prepared by the Bureau Of Mines Of San Diego County. For data regarding mines that were flooded and impossible to enter at the time Of the survey, resort was made to former reports Of the State Division Of Mines, supplemented by information furnished by owners Of the properties. A final field check on Operating properties was made by the senior author late in 1938. Primarily, the main Objective Of this report is to indicate present and potential mining activities in San Diego County. Occasional reference has been made to events Of historic interest. For detailed information on the geological and physiographical features of the county, the reader is referred to exhaustive reports which have been previously published, mention of which is made later.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from California Journal of Mines and Geology, Vol. 54: January 1958 During 1956, for the first time in history, the value of the mineral production of California exceeded a billion and a half dollars - a 7 percent increase over 1955. For 6 consecutive years the mineral pro duction has registered an all-time high, and for 9 successive years it has exceeded the 1 billion dollar mark. This vast wealth may be attributed first. To the mineral fuels - oil and gas percent) second to the nonmetallic minerals per cent); and third to metallic minerals percent). It is the decline in the production of some of the metallic minerals which brings forth the statement that mining is now in the doldrums; but the nonmetallic mineral industries are soaring to new heights, and for reasons of simple economics, the future for these useful commodities is exceedingly bright. Production of some of the metallics - iron, lead, zinc, and chrome - walso increased. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
