Show DISPLACEMENT OF COAL BY OIL On accounr of thp large production I of petroleum in California and Its 1186 for fuel, coal mining has prac-'tlcally prac-'tlcally ceafed In that state, the pro-I pro-I duct Ion In the last two years beins 'only 10.747 tons in 1 0 1 1 anJ 10.97$ . tonstons in 112, according to Edward W. Parker of t'ue United States Geological Geo-logical Survey The production of petroleum In California Cali-fornia In 1912 was 86,4;.0.767 barrels. !of which not less than 50.000.000 bar rcls was used directly for fuel Lare quantities of oil are al60 used In place : of coal for gas makln;. and on the es-timate es-timate that three and a half barrels of petrole-:m is equivalent to one ton of ordinary bituminous coal, It Is probable prob-able that from 1,400,000 to 1,500.000 'tons of coal would be required to perform per-form In California the service now rendered ren-dered by petroleum in the production of heat, light and power. California oil is the principal fuel for locomotives as far north as Washington and across the Sierra and Cascade ranges, its fredon from sparks serving as a IgTeat protection arainst forest fires, as compared with coal or wood fuel. (It Is used almose exclusively on Inland In-land and coastwise steamers, and to 'an Increasing extent by the transpacific transpa-cific steamers. It has even displaced jcoal on Pueet ound. mauy of the 'steamers of the Canadian Pacific fleet plying between Vancouver, Victoria and other points having been equipped for oil burning. There is still, how-sver how-sver some demand for coal in California, Cali-fornia, practically for domestic use and for bunker trade at San Francis-eo Francis-eo i t Its is almost exclusively supplied sup-plied by coals from other states and from abroad There are. however. In California, a number of small, widely separated 'coal fields, chief among which are the J Mount Diablo field of Contra Co&tra county the Corral Hollow field of Ala-imeda" Ala-imeda" county, the West valley aud Trafton fields of San Benito county land the Stone Canyon field of Mon Ucrcv county The first two. which are on the eastern border of San Fran- cisco bay. and consequently In the 'west-central part of the state, produce black llgnllf or subbltumlnous coal. The ooali of Monterey county ar of th- same geologic as those farther north, but they have been altered Into true bituminous coals. The alteration al-teration in the San Benito county areas has not progressed so far as In Monterey county, but the coals closely approach the bituminous grade None Ol thorn possess rooking qualifies. |
