September, 1928. To His Excellency, The Honorable C. C. Young, Governor of the State of California. Sir : I have the honor to herewith transmit Bulletin No. 101 of the State Division of Mines and Mining, being the annual report of the statistics of the mineral production of California. The remarkable variety, total valuation, and wide distribution of many of our minerals revealed herein show California's importance as a producer of commercial minerals among the states of the Union. Respectfully submitted. Walter W. Bradley, State Mineralogist. I I INTRODUCTION It is tlie endeavor of the staff of tlie State Mining Bureau (now Division of ]\Iines and Mining' of the State Department of Natural Resources), in these annual reports of the mineral industries of Cali- fornia, to so compile the statistics of production that they will be of actual use to producers and to those interested in the utilization of the mineral i)roducts of our state, while at the same time keeping the individual's data confidential. In additicm to the mei-e figures of out- put, we have included descriptions of the uses and characteristics of many of the materials, as well as a brief mention of their occurrences. The compilation of accurate and dependable figures is an extremely j difficult undertaking, and the State Mineralogist takes the opportunity of here expressing his appreciation of the cooperation of the producers i in making this work i:)ossible. A fuller appreciation of the value of j early responses to the requests sent out in January will result in earlier ll completion of the manuscript. Statistics lose much of their value if ; their i)ublication is unnecessarilv delaved. Some of the data relative to properties and uses of many of the minerals herein described are repeated from preceding reports, as it is intended that this annual statistical bulletin shall be somewhat of a compendium of information on California's commercial minerals and llieir utilization. Walter W. Bradley, State Mineralogist. MINERAL INDUSTRY, CALIFORNIA, 1927 DATA COMPILED FROM DIRECT RETURNS FROM PRO- DUCERS IN ANSWER TO INQUIRIES SENT OUT BY THE CALIFORNIA STATE DIVISION OF MINES AND MINING, FERRY BUILDING, SAN FRANCISCO, CALIFORNIA CHAPTER ONE The total value of tlie mineral output of California for the year 1927 was $366,781,394, being a decrease of $83,549,462 under the 1926 total of $450,330,856. There were fifty-eight different mineral substances, exclusive of a segregation of the various stones grouped under gems; and all of the fifty-eight counties of the state contributed to the list. As revealed by the data following, the salient features of 1927 com- pared with the preceding year were : A large drop in the value of petroleum in an amount greater than the net decrease in the grand total for all substances, being only partly offset by increases in other items. Material advances were made by borates, cement, potash, natural gas, granite, limestone, quicksilver, sandstone, and soda. Decreases were reg- istered by copper, zinc, miscellaneous stone, brick, lead, salt, and silver. Petroleum showed a decrease in value of $84,811,179, although there was an increase from 224,637,281 barrels to 231,195,774 barrels. This was due to a sharp cut in the price of crude oil, mainly for grades over 20° Baume, effective April 16, 1927. There were a number of other minor variations, the result being a decrease in the totals of the fuels and metals groups, while all other groups showed increases. Of the metals, titanium was added to the list, being the first year of any record of its production in commercial quantity in California; quicksilver increased from 5892 flasks worth $516,382 to 6488 flasks worth $714,418, this being accounted for by the advanced price received by the producers. In 1926 they received $87.64 and in 1927, $116.94 per 75-pound flask. Copper decreased from 33,521,544 pounds worth $4,693,014 to 27,350,316 pounds worth $3,582,885 ; gold from $11,923,- 481 to $11,671,018; lead from 8,067,873 pounds worth $645,429 to 2,748,440 pounds worth $173,151; silver from 2,022,460 fine ounces worth $1,262,015 to 1,620,242 fine ounces worth $918,677; and zinc from 20,447,559 pounds worth $1,533,568 to 8,625,004 pounds worth $552,000. The decrease in copper, lead and zinc was due to a drop in the market prices, while the gold and silver, by-products of these ores, account for the decreases in the total gold and silver figures. Though 12 MINERAL INDUSTRY OF CALIFORNIA tlie gold yield decreased in value, California continues in the lead, and in 1927 accounted for approximately 26 per cent of the gold output of the United States. Of the structural group : Cement advanced from 13,797,173 barrels valued at $25,269,678 to 14,661,783 barrels at $26,474,935, though the avej-age price per barrel dropped from $1.84 to $1.80; granite increased in value from $655,332 to $3,398,443, and sandstone from $17,500 to $205,400; brick and hollow building tile dropped from a valuation of $7,026,124 to $6,516,077, and miscellaneous stone from $19,859,873 to $18,912,994; of the remaining minerals in this group there were no material changes. Of the industrial minerals there were a number of fluctuations with a general trend of increasing production and value. The important changes were : i)otterv clav with an increase from 797,461 tons valued at $806,509 to 867,419^ tons and $872,661; lime- stone from 108,795 tons valued at $367,501 to 899,790 tons and $663,- 957. Of the saline group, borates showed an increase from 47,605 tons valued at $1,625,298 to 72,462 tons at $3,043,260; potash, 32,884 tons valued at $812,285 to 67,340 tons and $1,952,852; and salt showed a decrease from 311,761 tons valued at $1,124,978 to 263,028 tons and $639,127. The figures of the State Divi.sion of Mines and Mining are made up from reports received direct from the producers of the various minerals. Care is exercised in avoiding du])lication, and any error is likely to be on the side of undei-- rather than over-estimation. California yields, commercially, a greater number and variety ofj mineral products than anj'' state in the United States, and probably] more than any other equal area elsewhere on the earth. The total! annual value of her output has been surpassed by not more than four' or five others, and those usually the great coal states of east of the IMississippi. More recently California has been placed second to Penn- sylvania, the leader. California was for many years the sole domestic source of borax, chromite and magnesite, and in which we still lead. "We lead all other states in the production of gold, quicksilver, and platinum ; and have alternated in the lead with Colorado in tungsten, and with Oklahoma in petroleum. The mineral industries, not only in California, but throughout the country, have reached quite a different phase from that of the old gold-rush days more than fifty years ago. A broader and more inti- mate status has been attained, touching practically every avenue of domestic and commercial endeavor. As quoted in a former report^ of the freight handled by the railroads of the country, the products of the mines represent 51.33 per cent. While gold, in which California still leads the United States, is still important, other metals and even nonmetals have superseded it in annual value. The greatest commer- cial developments proportionately in California in recent years have taken place among the industrial and structural minerals, not to men- tion petroleum, which leads all others in value. This introduces a new factor which requires study and attention — that of marketing. The gold miner could, and still does, take his metal to the mint and receives ' Cal. State Min. Bur., Bulletin !)6, p. 12, 1925. STATISTICS OF ANNUAL PRODUCTION 13 its equivalent in the 'coin of tlie realm'; and he knows from day to day and year to year, Avithout variation, just how much each ounce of gold will bring in that coin, though its equivalent in other commodities varies according to economic conditions. Marketing and competition, however, are vital factors in the industrial and structural groups. 14 MINERAL INDUSTRY OF CALIFORNIA m o 03 + ta la IV) 00 « 2 53 e,s St) t-t r-( 00 M* CO T-t CO 00 O C^ lO OO COt^ C5 cc t^ «o lO «D tH o i^ oo O^ rn t^ Ij:^ t>- C^ -^ ^ O LO Cq OS O W iH CO ^H lO t-- -^ LO U5 O rH CO "^ I> lO CO "^ CO CO Irt O ^ CO 00 O CO •^ 00C5 O'^OtH * tH CO t- Tj* o "^ tH t- CI CO -^ t- * t~ CO * CO OS -^ T-H C<1 in IJ^ !>• O 00 Ci l^ CO li^ OS -^ (N C^ t>* Ol-fSMC tHO c >o:)aiLocgc^coocH T-lOO rHW^IMOSOjOOOO "^T-ICTSt- C0O5 00 iH iH iH'*T-l CO tH 00 C^ O CO o cs !^ ^ 1— ( r> CO qn ■7; • rH CO CX) =+-! ,— ' o • S WH rr: r-H O.' a ■ (—• CO 1— » CO c/; ,0 :/?

More or less gas usually accompanies the petroleum in the oil fields, and such gas carries varying amounts of gasoline. A total of 142 plants Avere in operation in 1927 recovering gasoline by compression or absorp- tion from this 'casing-head' gas. After the gasoline is extracted the remaining 'dry gas' .so far as practicable is taken into pipe lines, by Avhich it is distributed to consumers, both domestic and commercial. In certain of the oil fields, some of the casing-head gasoline is obtained as an incidental product to the compressing of the natural gas prelim- inary to its transmission to consuming centers through the gas pipe lines. Some concerns market the casing-head gasoline separately, others blend it with distiller}^ gasoline, while others turn it into the oil pipe lines thus mixing this high-gravity gasoline with the crude oil for trans- portation to the i-efinery where it is later regained. A total of 489,- 798,683 gallons of casing-head gasoline valued at $45,700,264 from all fields was rei)orted as made bv 142 i)lants during 1927, compared Avith ;}89,()26,757 gallon.s valued at $r)1.788,;}46 fi-nin 148 plants in 1926.

The large refiners are also large ])roducers of crude oil which they send direct from well to plant, hence much of the crude oil is not sold as such. The values used in the statistical reports of the State ]\Iining Bureau since 1914 have been derivfd from averages of actual sales of crude oil of all grades in each field of the state, and these averages applied to the total yield of the respective fields. This we feel is a safer measure of commercial values than market quotations, because quotations do not always mean sales. This is particularly true on a rising or a falling market. Features of 1927. The noteworthy features of the year 1927 in the oil industry were increa.sed output in Orange, Santa Barbara and Ventura counties and decreases in all other counties. There were sharp cuts in the price of crude oil in all grades over 20° Baume, making the value in all counties less than in 1926. Summarizing the data for the year, the State Oil and Gas Supervisor ^ presented the following figures : "The total production of oil in the .state for the last six months of 1927 was 114,891,618 barrels of oil and 58,897,272 barrels of water. The production of oil for the year 1927 was, therefore, 231,045,773 barrels, an increase of 6,522,349 barrels over that of 1926. The increased production came from the Seal Beach and Hunt- ington Beach fields and while the Ventura field increased over 3,000,000 barrels, there was a nearly equal decrease in the fields of Kern County. "The production of oil for the second half of 1927 was 1,262,537 barrels less than for the first half. Water production increased 3,290,754 barrels during the .same period. * * * "The estimated closed-in production was increased during 1927 from 61,314 barrels daily in January to a maximum of 89,442 barrels daily in May and decreasing to 77,107 barrels daily in December. * * * "Storage and Price Changes. "The total crude oil and refined petroleum in storage in Pacific coast territory at the end of 1927 was 137,395,067 barrels, according to the American Petroleum Institute. The decrease in storage during the year amounted to 8,217,109 barrels compared with a decrease of 11,704,133 barrels during 1926. The total amount of crude and refined oil shipped to eastern ports during 1927 was 33,080,000 barrels, or 42,000 barrels more than the 1926 shipments. "On April 1, 1927, prices of crude oil of 15 degrees gravity and above in some fields, and of 19 degrees gravity and above in other fields, were lowered. "Drilling and Development. "During 1927, 1263 wells were reported to the State Oil and Gas Supervisor as ready to drill as compared with 1268 new wells in 1926. Five new fields were dis- covered in 1927, most of which are relatively unimportant. These fields were the Alamitos dome of the Seal Beach field, the Potrero field in Los Angeles County, the Rincon field in Ventura County, the Goleta field in Santa Barbara County, and the Round Mountain field in Kern County. Of these, the most important was the exten- sion of the Seal Beach field, which contributed much to the 1927 production. The productive possibilities of the Rincon, Potrero and Round Mountain fields had not been determined at the end of the year. The Goleta field produced a small amount of high gravity oil and apparently reached lis limit." During 1927 there was a small production of high-grade petroleum from Colusa County. This was marketed for medicinal purposes. ' Bush. R. D.. Resume of Oil Field Operations of California in 1927 ; Cal. State Min. Bur., 13th Ann. Rep. of State O. & G.

In 1919 and since, the average values have worked out at figures corresponding to quota- tions up to, in one year as high as 28° oil, due to the large yield of high-gravity oils from the new fields in the Los Angeles-Orange counties area. TOTAL PETROLEUM PRODUCTION OF CALIFORNIA The presence of oil seepages and springs in Los Angeles and Ventura counties was known and utilized in a small way early in the history of California. Some also was shipped to refineries at San Francisco from Santa Barbara and Humboldt counties. In the light of present-day 4 STATISTICS OF ANNUAL PRODUCTION 25 developments, the following reference to the previous year's production of oil and its future prospects as expressed by the San Francisco Bulle- tin of January 8, 1866, is strikingly prophetic even though skeptical : "It is possible that the small quantity received (40,000 or 50,000 gallons in 1865) may be the forerunner of many millions which will, at some future time, lubricate the wheels of commerce and set a trade at work excelling in variety any that has thus far been known on this coast. At present, however, we admit to being a little skeptical about the assumption of the astute Professor Silliman that California will be found to have more oil in its soil than all the whales in the Pacific Ocean." According to Hanks,^ in 1874 production amounted to 36 bbl. per day from natural flows in Pico Canon (Newhall), and at Sulphur Mountain (Ventura County), the oil being of 32° gravity average. " "Work was commenced in Pico Canyon in 1875 by drilling three shallow wells with spring pole, all of which yielded oil at depths of from 90 to 250 feet. Actual work of development commenced with steam machinery in 1877.'' In 1877 Pico averaged 40-50 bbl. daily, and Ventura 80 bbl. daily. In 1878, there was some production (@ 60 bbl. per day, for a time) from wells in Moody Gulch, near Los Gatos, Santa Clara County, the oil being of 46° Baume. The first wells in the Coalinga, Fresno County, and Summerland, Santa Barbara County, fields were drilled in 1890, but Coalinga did not make its influence felt conspicuously on the state's annual output until 1903. The Summerland yield never has been large. The Salt Lake field near Los Angeles began production in 1894 and in 1897 reached over a million barrels annually. In the Kern Countv fields, the first well was drilled in Sunset in 1891, Midway in 1900"^ McKittrick in 1892, Kern River in 1899. The Sunset-Midway district attained a yield of over 4,000,000 bbl. in 1909, and over 20,000,000 bbl. in 1910. Kern River field produced over 3,000,000 bbl. in 1901. The first well in the Santa Maria-Lompoc group, Santa Barbara Countv, was drilled in 1901, and the district advanced to a yield of over 3,000,000 bbl. annually in 1905. The Whittier-Fullerton field in Los Angeles and Orange counties became an important factor in 1902. The Montebello field, Los Angeles County, was the conspicuous addition in 1918-1919 ; and Elk Hills, Kern County, with Huntington Beach and Richfield, Orange County, in 1920. In 1921, the new fields added were Long Beach and Santa Fe Springs, Los Angeles County; in 1922, Torrance field in Los Angeles County, and Wheeler Ridge field in Kern County ; but the production from the large number of new wells started in these new Los Angeles County fields did not reach its peak until August and September, 1923. Dominguez (Compton) came in during 1923; followed by Rosecrans and Inglewood in 1924. Ventura recorded important additions to its producing area in 1925 and 1926. Seal Beach, Orange County, and Mt. Poso, Kern County, were the new fields added in 1926 ; Round Mountain, Kern County, and Rincon, Ventura County, were the new fields added in 1927. ; 'Hanks, Henry G., Report IV of State Mineralogist, p. 298, 1884.

[Specific Gravity of Oils Produced. The proportion of heavy and light oil produced in the various fields lis shown in Table E, following, for M^hich we are indebted to the [Standard Oil Company. Under present practice, oil below 18° Baume lay be considered as largely refinable for fuel and lubricants, while Jthe lighter oils yield varying amounts of the higher refined products nth. corresponding proportions of residuum and fuel oil. Specific gravities in California range from 8° Baume in the Casmalia field. [Santa Barbara County, to 56° Baume in Ventura County. California crude oils are all essentially of asphalt base, with a few lotable exceptions. In the following localities are wells yielding crudes containing both asphalt and paraffine constituents : Oil City field, Coal- inga ; a few deep wells in East Side field, Coalinga ; a considerable part of the Ventura County fields ; Western Minerals area, south of Mari- copa ; Wheeler Ridge, Kern County. 28 MINERAL INDUSTRY OF CALIFORNIA TABLE E Production of Light and Heavy Oil, by Fields, 1927 Under 18° 18° and above Total Field {barrels) (barrels) (barrels) Kern River 6,185,160 6,185,160 Lost Hills-Belridge 414,692 1,108,564 1,523,256 McKittrick 1,845,117 1,845,117 Midway-Sunset 8,166,365 23,412,782 31,579,147 Klk Hills 1,622,129 8,474,919 10,097,048 Coalinga 3,713,483 3,429,962 7,143,445 Wheeler Ridge 375,425 375,425 Watsonville 23,725 23,725 Santa Maria — - 909,988 1,079,771 1,989,759 Summerland 52,525 52,525 Ventura-Newhall 57,675 2,159,465 2,217,140 Ventura Avenue 17,796,011 17,796,011 Los An&eles-Salt Lake 610,537 10,304 620,841 *Montebello 104,790 5,364,630 5,469,420 nVhittier 54,198 605,612 659,810 *Coyote 11,168 5,128,848 5,140,016 *FuIlerton 133,573 6,874,989 7,008,562 *Richfield 479,185 7,399,605 7,878,790 Santa Fe Springs 15,155,701 15,155,701 Huntington Beach 560,202 25,802,332 26,362,534 Torrance 3,310,942 5,050,855 8,361,797 Long Beach 252,549 34,310,762 34,563,311 Dominguez 3,860 5,890,028 5,893,888 Rosecrans 3,494,404 3,494,404 Inglewood 2,374,174 10,385,933 12.760,107 vSeal Beach 16,443,492 16,443,492 Ooleta 88,840 88,840 Rincon 6,000 6,000 Miscellaneous 11,898 572 12,470 Totals 30,897,935 199,849,800 230,747,741 * Formerly reported as Whittier-Fullerton. As ]n-evioiisly noted by Bradley,^ a decided change has taken place in the relative proportions of light and heavy crudes produced in Cali- fornia since 1910, taking 18° Baume as the dividing line. This subject has also been covered in detail and with charts, by Collom and Barnes." A marked drop took place in the low-gravity yield from 1910 to and including 1914. From 1914, it remained almost stationary, with a slight drop in 1921, while the high-gravity yield has increased at a rapid rate since 1915. The proportions have been reversed from approximatelv 75% low— 25% high in 1914 to 25% low— 75% high in 1921 ; 10% low— 90% high in 1923; 14% low— 86% high in 1924-1927. This has been an important factor in its effect upon the average price i)er barrel of the state's output in these years, as well as its effect upon tlie relative situation between production and consumption. It luus been a fortunate development, in view of the increased demand for refinery products (gasoline in particular). Oil in 'Storage.' Field, refinery, pipe-line, and tank-farm .stocks of crude and refined products in the Pacific Coast territory totaled 137,395,067 barrels^ December 31, 1927, compared with 145,612,176 barrels on December 31, 1926. The total decrease in stock for the year was 8,217,109 barrels. 1 Bradlev. "VV W., Mineral Production of California in 1921 ; Cal. State Min. Bur., Report XVIII, p. 442, Sept., 1922. = Collnm.

It Avill be noted that the state average yield of oil per well per day was 62.0 barrels for the first six months of 1927 and 59.6 barrels for the second. This is somewhat higher than the figure of 54.1 barrels average for December derived from American Petroleum Institute data as shown in Table D, on a preceding page, due in part at least, to the fact that the latter is on a full-time basis, whereas the Bureau figures alloAV for shut-down time. • Summary of Operations, California Oil Fields ; Cal.

Financial results of the oil business during 1927 are shown by the following tables. The features worthy of mention are : (1) There were 487 operating companies in 1927 Avith a total capitalization value of $1,272,555,286 (see Table G), which was a decrease in the number of companies from 491 in 1926 with an increased capitalization from $1,241,242,935. (2) A total increase in dividends was paid, with all counties showing an increase over their 1926 dividends, with the excep- tion of Fresno and Santa Barbara (see Table H). (3) An increase in the barrels per well per day (see Table I) in Santa Barbara and Ventura counties, with a decrease in all other counties and a marked drop in Los Angeles County. (4) A slightly less operating cost in all counties with the exception of Los Angeles and Orange. With reference to Table I, it should be noted that although it lacks data from the larger operators who have refineries and with interests in more than one field, yet the data given are of economic value and interest in that tliey indicate the conditions prevailing among the smaller companies and operators. Operating cost per well is not always lower for the dividend com- panies than others. Profitable operations seem to depend generally upon large wells, high-grade oil, and proximity to market. Price and profits have iLsually been greater in the Los Angeles-Orange-Ventura fields than in others, doubtless largely due to the proximity to market and higher grades of oil. Crude oil testing as high as 56° Baume is obtained from some of the Ventura wells. TABLE G. Capitalization Field Fresno County — Coalinga Kern County — Kern River .

Spurr and Wormser, "Marketing of Metals and Minerals." See also under each metal. The total value of metals produced in California during 1927 was $17,990,841. The chief of these is, and always has been, gold, followed by copper, silver, quicksilver, zinc, tungsten, lead, titanium, iron ore and platinum. There was a small output of antimony. There was no production of arsenic, cadmium, molybdenum, nor tin, which have in the past been on the active list. Deposits of ores of nickel and vanadium have also been found in the state ; although there has yet been no com- mercial output of them. The above-noted total of this group is a net decrease of $2,937,903 from the 1926 total of $20,928,744, due mainly to decreases registered by copper, gold and silver, in spite of an increase by quicksilver. California leads all states in the Union in her gold production and is credited with approximately 26% of the nation's yield in 1927. The precious metal is widely distributed through the state. Thirty-four of the fifty-eight counties reported an output in 1927 from either mines or dredges. Copper, which is second in importance among the metals of the state, occurs in the following general districts : the Shasta County belt, which has been by far the most important ; the Coast Range deposits, extending more or less continuously from Del Norte in the north to San Luis Obispo County in the south ; the Sierra Nevada belt, starting in Plumas and running in a general southerly and southeasterly direction through the Mother Lode counties and ending in Kern; the eastern belt in Mono and Inyo counties, and the southern belt in San Bernar- dino, Riverside and San Diego counties. Silver is not generally found alone in the state, except notably in the Rand district, San Bernardino County ; but is associated to a greater or less extent with gold, copper, lead and zinc. Quicksilver has for many years been one of the state's staple prod- ucts and California has supplied approximately 75% of the nation's output of this metal. Tungsten is found in but few other localities of importance in the United States. Large deposits of iron ore have long been known in several sections of the state, but for various economic reasons this branch of the mineral industry thus far has made only slight progress on the Pacific Coast. Titanium is associated with some of California's iron deposits. This mineral is widely distributed through the United States, but the deposits of this state are among the few that are considered of com- mercial importance. Although the United States is a large consumer of certain metals, in fact the largest particularly of chromium and tin, our production from domestic sources is deficient.

Copper Production of California by Years. Although some mining of copper ores in a small way had been done earlier, shipments in appreciable quantities began in 1861 and con- 46 MINERAL INDUSTRY OF CALIFORNIA tinued of importance up to the end of 1867, when a total of 68,631 tons (of 2376 pounds) of high-grade ores, and 847 tons of matte or 'regulus'^ had been shipped to smelters at New York, Boston, and Swansea, Wales. The most important district at that time was Copperopolis and vicinity in Calaveras County, with some shipments also made from Mariposa, El Dorado, Fresno, and San Luis Obispo counties. From 1868 to 1882, the output was insignificant. There are wide discrepancies in the figures currently recorded for copper production previous to 1882 in which year the data of the U. S. Geological Survey began. The detailed statis- tics of the California State Mining Bureau began in the year 1894.

Although now surpassed for a number of years in annual value hy petroleum, and by cement beginning with 1920, it still heads our metal list, and California continues to outrank all the other gold-producing states of the United States, including Alaska. In fact, at present, California is producing approximately 26% of the gold mined in the entire United States. While there is some renewal of activity in the development of gold placer properties, it has not yet become reflected in an increased yield of the metal. In fact, the 1927 figures show a decrease from the 1926 values. The gold yield has decreased in recent years, not only in California but in the country as a whole. Meanwhile, the actual gold reserves (monetary stock on hand) of the United States has increased to such an extent that we now hold practically one-half of the world's stock. 1 Brown, J. Ross, Mineral Resources West of the Rocky Mountains, p. 168, 1867. STATISTICS OF ANNUAL PRODUCTION 47 The production of gold in California in 1927 totaled 564,585.50 fine ounces, worth $11,671,018, being a decrease of 12,212.90 fine ounces from the 1926 yield. The ' deep ' or lode mines output accounted for $5,833,705, and the placers (mainly the dredges) produced $5,837,- 313. As the Division of Mines and Mining has never independently gathered the statistics of the gold and silver production, these figures, as in former years, are published b}" cooperation with and through the courtesy of Mr. J. M. Hill of the Division of Minerals and Statistics, U. S. Bureau of Mines. Distribution of the 1927 gold production, by counties, was as follows : County Alpine Amador Butte Calaveras Del Norte El Dorado _.

It will be noted as in 1926 Yuba County was the largest gold producer, with Nevada, Amador, and Sacramento following respectively in the same order. The Yuba and Sacramento production came almost entirely from dredges, while that from Nevada and Amador came mainly as lode gold. The following is quoted from the advance chapter on Gold in 1927, by courtesy of Mr. J. ]\I. Hill of the U. S. Bureau of Mines : "The value of the mine production of gold in California in 1927 decrea.sed $252,463, or 2 per cent, as compared with 1926. Lode mines yielded 50 per cent and placer mines 50 per cent of the total gold in 1927, as compared with 56 per cent and 44 per cent in 1926, 61 per cent and 39 per cent in 1925, and 65 per cent and 35 per cent, respectively, in 1924. "Four counties produced more than $1,000,000 each in gold in 1927 as compared with four counties in 1926 ; Sierra County mines did not reach the million mark in gold value in either 1927 or 1926. Yuba, with $3,468,201, produced largely by dredges, was first in rank; Nevada, with $2,127,195, largely from gold lode mines, was second; Amador, with $1,922,714. almost entirely from gold lode mines, was third; and Sacramento, with $1,211,278, entirely from placers, mostly worked by dredges, was fourth. The fifth largest output of gold, $678,873, came from Sierra County, largely from gold lode mines, and was followed by Trinity County with $409,492, largely from dredge and hydraulic placer mines. Calaveras County, which was fifth in rank in 1926, dropped to eighth place in 1927, being preceded by Plumas County in its value of gold. "The yield of gold from 465 placer mines in 1927 was valued at $5,837,313, an increase of 12 per cent as compared with the placer output from 483 mines in 1926. There was an increased gold yield of 10 per cent by dredges, 28 per cent by drift mines, 75 per cent by hydraulic, and 16 per cent by surface mines, respectively, as compared with 1926. In 1927 dredges yielded 9 4 per cent, drift mines 2 per cent, hydraulic mines 2 per cent, and surface workings 2 per cent of the gold from California placer deposits. Production of gold by 25 dredges operating in 1927 was $5,461,929, as compared with $4,950,545, by 23 dredges in 1926 and $4,750,842 by 24 dredges in 1925. "The output of gold from 318 lode mines in California in 1927 was valued at $5,833,705, a decrease of 13 per cent as compared with 1926, following declines of 16 per cent in 1926 from 1925 and 7 per cent in 1925 from 1924. 48 MINERAL INDUSTRY OP CALIFORNIA "Gold ore and tailings treated in 1927 yielded 93 per cent, copper ore and tailings yielded 6 per cent, and silver ore and tailings yielded 1 per cent of the total gold from lode mines. Amalgamation mills in 1927 recovered approximately 75 per cent, cyanidation plants 15 per cent, and smelters 10 per cent of the gold lode output of California, as compared with 75 per cent, 17 per cent, and 8 per cent, respectively, in 1926. "It is estimated that approximately 4 per cent of the gold output from lode jnines was stolen and sold by 'high graders' in 1927, a reduction of 2 per cent over each of the two preceding years. "In 1927 there were 33 companies in the state that produced more than 1000 ounces of gold each, and they contributed 91 per cent of the total gold output of the state. This is a decrease of 1 per cent from the 34 companies that produced more than 1000 ounces each in 1926. Of the 33 larger companies 7 produced more than 20,000 ounces each and 2 more than 50,000 ounces; 1 1 of them operated 22 gold dredges, 2 drift placer mines, 1 a silver mine, 3 operated copper mines, and 10 operated gold lode mines. The 10 largest gold-producing companies in California in 1927, in order of output, were the Yuba Consolidated Gold Fields (6 dredges), Natomas Company of California (6 dredges). Empire Mines Company (gold lode), Kennedy Mining and Milling Company (gold lode), North Star Mines Company (gold lode), Original Sixteen to One Mine (Inc.) (gold lode), Argonaut Mining Company (gold lode), Central Eureka Mining Company (gold lode), Walker Mining Company (copper mine), and the Original Mining and Milling Company (gold lode)." Total Gold Production of California. The presence of gold in stream gravels near Los Angeles was known and worked in a small way by the Indians, at least as early as 1841/ and possibly 1820.- On March 2, 1844, Don Manuel Castanares, deputy for California to the Congress of Mexico, reported^ to his government that placers near Los Angeles had produced up to December, 1843, a total of 2000 ounces of gold dust, most of which had been sent to the United States mint at Philadelphia. As the padres and the rancheros discouraged the quest of gold this early, small production caused no particular excitement. It was not until James W. Marshall's finding of gold nuggets in the tail-race of Sutter's saw mill on the American River, January 24, 1848, was heralded abroad that the great ru.sli began, and California became a common- wealth of first rank almost over night. There are, however, no authentic 'data on gold production prior to 1848, other than occasional, scattered references such as above quoted. The following table was originallj' compiled by Chas. G. Yale, of the Division of Mineral Resources, U. S. Geological Survey, but for a num- ber of years statistician of the California State Mining Bureau and the U. S. Mint at San Francisco. The authorities chosen for certain periods were : J. D. Whitney, state geologist of California ; John Arthur Phillips, author of "Mining and Metallurgy of Gold and Silver" (1867); U. S. Mining Commissioner R. W. Raymond; U. S. Mining Commissioner J. Ross Browne ; Wm. P. Blake, Commissioner from Cali- fornia to the Paris Exposition, where he made a report on "Precious Metals" (1867) ; John J. Valentine, author for many years of the annual report on precious metals published by Wells, Fargo & Com- pany's Express; and Louis A. Garnett, in the early days manager of the San Francisco refinery, where records of gold receipts and ship- ments were kept. Mr. Yale obtained other data from the reports of the director of the Q. S. Mint and the director of the U. S. Geological Survey. The authorities referred to, who were alive at the time of the original compilation of this table in 1894, were all consulted in person or by letter by Mr, Yale with reference to the correctness of their published data, and the final table quoted was then made up. ^Hittell, T.

Small amounts of manganase ore from California have been shipped in past years to steel plants along the Pacific Coast. These ores showed analyses of from 45% to 55% Mn and were utilized by plants for ferromanganese. Importations of foreign manganese ores to the United States in 1927, mainly from Brazil, amounted to a total of 622,067 long tons valued at 8,487,016, compared with 368,341 tons and $11,075,771 in 1926. The Tariff Act of 1922 provides for an import duty of 1^ per pound on the metallic manganese contained, for "manganese ore or concen- 52 MINERAL INDUSTRY OF CALIFORNIA trates containing in excess of 30 per centum of metallic manganese." The bulk of such ore is consumed in the large steel-producing centers of the eastern United States. Much valuable research work has been done in recent years, particu- larly by companies operating in Montana and Virginia, in the benefi- ciation of manganese ores. The success of their processes appears assured. In reply to the recent suggestion of certain steel interests to have the manganese import duty removed, the manganese operators have organized the American Manganese Producers' Association, which will work for retention of the tariff. Such retention will enable the domestic industry to grow and to further develop ore-dressing methods that will make available large tonnages of low-grade material not now marketable. Manganese Ore Production in California, by Years. Production of manganese ore in California began at the Ladd Mine, San Joaquin County, in the Tesla District in 1867. When shipments of this ore to England ceased late in 1874, upwards of 5000 tons had been produced by that property. For some j^ears following that, the output was small.

Bulletins 67, 91. U. S. Bur. of Min., Bulletin 111. Proc. Colo. Sci. Sec, Vol. XI. Molybdenum is used as an alloy constituent in the steel industry, and in certain forms of electrical apparatus. Included in the latter is its successful substitution for platinum and platinum-iridium in electric contact-making and -breaking devices. In alloys it is used similarly to and in conjunction with chromium, cobalt, iron, manganese, nickel, tungsten, and vanadium. The oxides and the ammonium salt have important chemical uses. STATISTICS OF ANNUAL PRODUCTION 53 The two principal molybdenum minerals are : the sulphide, molyb- denite ; and wnlf enite, lead molybdate ; the former furnishing prac- tically the entire commercial output. Molybdenite is found in or asso- ciated with acidic igneous rocks, such as granite and pegmatite. The chief commercial sources have been New South Wales, Queensland and Norway, with some also from Canada ; but the United States is now able to supply its own requirements. The growing consumption of molybdenum by alloy-steel makers in the United States has been stimulated by the fact that molybdenum alone of the steel-alloying metals can be produced commercially in the United States to an extent which avoids all necessity for importation. Another fact has been the marked adaptability of molybdenum steels to large-scale production of automobile and other parts. The most important development of 1924—1925 was the elimination of ferromolybdenum from the market due to the substitution of calcium molybdate as the furnace addition by the entire alloy-steel industry. Calcium molj^bdate is stated to be not only easier and less costly to prepare, but it introduces the molybdenum into the steel bath in a much purer form, the resulting steel being superior to that made with ferromolybdenum. Deposits of disseminated molybdenite are known in several localities in California, and in at least two places it occurs in small masses associated with copper sulphides. The only recorded commercial ship- ments of molybdenum ore in California were during the war, 1916- 1918. Some development work has been recently done on a high-grade deposit at the head of the Kaweah River, Tulare County.

In California the platinum group metals are obtained as a by-product from placer operations for gold. The major portion of it comes from the dredges working in Butte, Sacramento, Stanislaus and Shasta countiCvS, with a small amount coming from the hydraulic and surface- sluicing mines of Del Norte, Humboldt, Siskiyou, and Trinity counties. Tlie production of platinum metals in California for 1927 totaled 183 ounces crude, containing 139 fine ounces valued at $10,757, com- pared with tlio 1926 figures of 322 fine ounces and $32,005. Of this amount 102 fine ounces or 73% came from the gold dredges. In addition to the above metal there was some platinum mined but not sold in 1927 in Butte, Trinity and Yuba counties. Of the al)ove 183 fine ounces at least 37 fine ounces were iridium, osmium, palladium and ruthenium. Most of the platinum refiners pay for the osmiridium on the basis of its iridium content. Crude 'platinum' is really a mixture of the metals of that group, and car- ries varying percentages of platinum, iridium, osmiridium or iridos- mine, with occasionally some ruthenium and palladium. In addition to the above-noted production, there is usually some platinum recov- ered as a by-product in the gold refinery of the mint, but which can not be assigned to the territory of its origin for lack of knowing to which lots of gold it belongs. Some platinum and palladium are also recovered in the electrolytic refining of blister copper. For 1926, the distribution by counties of California's platinum yield was as follows : County ■ Fine ounces Value Butte" 7 $499!

Besides its well-known uses in jewelry, dentistry and for chemical- Avare, an important industrial development of recent years employs platinum as a catalyzer in the 'contact process' of manufacturing con- centrated sulphuric acid. It is also necessary for certain delicate parts of the ignition systems in automobiles, motor boats and aeroplanes. Experiments have been made to find alloys which can replace platinum for dishes and crucibles in analytical work, but so far with only slight || success.

The production of quicksilver for 1927 in California was 6488 flasks ('of 75 pounds, avoirdupois) valued at $714,418. This was an increase in both quantity and value over the 1926 figure of 5892 flasks valued at $516,382. This production came from Lake, Monterey, Napa, Orange, San Benito, San Luis Obispo and Sonoma counties, the largest production coming from San Benito, with Napa in second place. The average price received during 1927, according to the producers' New Idria Mine at Idria, San Benito County. This mine is the largest quicksilver producer in the United States. Photo by Walter W^ Bradley. reports to the Division of Mines and Mining, was $111.67 per flask, as against $89.64 in 1926, and the record average of $114.03 for the year 1918. During 1927 there were sharp fluctuations of quotations on quick- silver. The year started at $100.33, going to $123.33 in April, and ending the year at $129.50. In June the price quoted changed from a 75-pound flask to a 76-pound flask. The average quotations for quicksilver in 1927 were $117.25 for a 76-pound flask at San Francisco, or $115.71 (for 75 pounds), against $87.64 (75 pounds) in 1926. The average quotations for 1927 in New York were $118.16 for a 76-pound flask, or $116.60 for a 75-pound flask. li STATISTICS OF ANNUAL PRODUCTION 57 The U. S. Bureau of Mines reported the total production of the United States for 1927 at 11,276 flasks valued at $1,314,782 (using $116.60 as the average of New York quotations). Outside of Cali- fornia, the principal yield came from Texas and Washington, with a few flasks from Nevada, Alaska, Arizona, and Idaho. California pro- duction was approximately 53% of the total. The imported quicksilver ^ in 1927 amounted to 24,650 flasks. Of these, 13,663 flasks came from Spain, 9089 flasks from Italy, and 1843 flasks from Mexico. The rise in price in the last quarter of 1926 and 1927 was due to an increased demand in the United States, as shown by the increased production and imports and the continued demand of continental Europe. Uses. The most important uses of quicksilver are the recovery of gold and silver by amalgamation, and in the manufacture of fulminate for explo- sive caps, of drugs, of electric appliances, and of scientific apparatus. By far the greatest consumption is in the manufacture of fulminate and drugs. Radio tubes and electrical appliances are taking increasing amounts. Total Quicks! . ver Pro duction of California.

Though the New Almaden Mine in Santa Clara County was first worked in 1824, and has been in practically continuous operation since 1846 (the yield being small the first two years), there are no available data on the output earlier than 1850. Previous to June, 1904, a 'flask' of quicksilver contained 76i pounds, but since that date 75 pounds. In compiling this table the following sources of information were used: for 1850-1883, table by J. B. Randol, in Report of State Mineralogist, IV, p. 336 ; 1883-1893, U. S. Geological Survey reports ; 1894 to date, statistical bulletins of the State Mining Bureau; also State Mining Bureau, Bulletin 27, "Quicksilver Resources of California," 1908, p. 10 .

Except for the early-day production from the silver mines of the Calico district and the more recent production from those of the Randsburg area, both of which are in San Bernardino County, the recovery of silver in California has been largely as a by-product from its association with copper, lead, zinc, and gold ores. In 1927 silver production of California totaled 1,620,242 fine ounces valued at $918,677, compared witli 2,022,460 ounces values at $1,262,- 015 in 1926. Of the 1927 yield 20,903 ounces valued at $11,852 came from placers. The average price of domestic silver during 1927 was 56.7^^ per ounce in New York against 62. 4f in 1926. The figures below are those of the U. S. Bureau of Mines, Depart- ment of Commerce (as explained under Gold).

S. Bureau of Mines, Department of Commerce, Advance Chapter on Gold and Silver for 1927, by courtesy of Mr. J. M. Hill, statistician in charge of the San Francisco branch office : "The mine production of silver in California in 1927 was 1,620,242 ounces, valued at $918,677, a decrease of 20 per cent in quantity and 27 per cent in value as com- pared with 192G. Three counties yielded more than 100,000 ounces of silver each in 1927, namely, San Bernardino County, with 788,580 ounces largely from silver ore produced by the California Rand Silver (Inc.) ; Plumas County, with 315,887 ounces, largely from copper ores of the Engels and Walker mines ; Shasta County, with 123,917 ounces, largely from zinc and copper ores. Inyo and Mono counties were in the 100,000 ounce cla.ss in 192G, but each produced less than 100,000 ounces in 1927. The fourth largest producer of silver was Napa County, with 99,532 ounces from silver ores, and this was followed by Inyo County, with 83,570 ounces, mostly from lead ores. "The yield of silver from placer mines in 1927 was 20,903 ounces, 8 per cent more than in 1926 and over 1 per cent of the total silver output of the state. Of the 1,599,339 ounces of silver produced at lode mines in 1927 silver ore and tailings yielded 58 per cent (same as in 1926), copper ore and tailings 25 per cent (20 per »30- no 110 100 90 80 70 60 50 Range vi'.raqi ■ g MMNCjCXIRNAL Prices of SAR SILVER.

"Each of 43 properties in 1927 produced more than 1000 ounces of silver as compared with 46 properties in 1926, and these mines yielded 98 per cent of the total silver produced in the state in both 1927 and 1926. At 27 properties the yield was between 1000 and 10,000 ounces (31 in 1926), at 13 between 10,000 and 100,000 (10 in 1926), at 2 between 100,000 and 300,000 (4 in 1936), and at 1 mine in excess of 700,000 ounces in 1927. No mine in California produced as much as 1,000,000 ounces of silver in 1927. The 10 largest producers of silver in California in 1927 in order of output were the California Rand Silver (Inc.), Walker Mining Company, Engels Copper Mining Company, Palisades Mines Company, California Zinc Company, Mason Mining Company (Balaklala), Mono Mining Company of Nevada, American Metals (Inc.) (Darwin), North Star Mines Company, and the Santa Catalina Island Company." Silver Production of California, by Years. The amount and value of the silver production of California, and the average price, annually, since 1880 are given in the table following. In the table shown in the statistical bulletins previous to Bulletin 97 60 MINERAL INDUSTRY OF CALIFORNIA (for 1925), the values sho^VIl for 1880-1904 (inc.) were taken from the reports of the Director of the Mint, of which the figures for 1880-1896 (inc.) were based on 'coinage value' ($1.2929 per fine ounce). We have recalculated these to commercial value, using the price table of the U. S. Geological Survey (McCaskey, H. D., Gold and Silver, 1913: Mineral Resources of the U. S., Part I, p. 847).

There Avas an output from the district during 1891-1892 as tabulated below. Small quantities of stream tin have been found in some of the placer workings in northern California, but never in paying amounts. Two occurrences have also been noted, in northern San Diego County. Crystals of cassiterite were found there, associated with blue tourma- line crystals, amblygonite and beryl. No commercial quantity has been developed, only small pockets liave been taken out. The principal sources of the world's supply of tin are the islands of Banka, Billiton and Singkep, Netherlands India (Dutch East Indies), followed by the Federated Malay States (Perak, Pahang, Negri Sem- bilan and Selangor). Bolivia, Siam, Cornwall, Transvaal, New South Wales, Queensland and Tasmania are also important sources. A measureable amount of the metal is also recovered by detinning scrap and old cans.

In 1927 for the first time titanium minerals were mined in Cali- fornia. These operations were in Los Angeles County, where one of the largest deposits of titanium ore in the United States is located. There were two separate operations, one worked the black beach sands, which probably contained approximately 20% titaniferous iron and magnetite, the gangue being silica and several silicates. The other is a lode deposit in the San Gabriel Mountains. Titanium is widely distributed in a variety of minerals, but its commercial sources are limited to three forms, rutile (oxide), ilmenite (titanite), and titaniferous magnetite (iron ore rich in titanium). There are several known areas where large deposits of these minerals are found in America, mostly titaniferous iron. Of the titaniferous iron deposits only a portion of the Adirondack deposit, some small deposits in North and South Carolina, and those in Los Angeles County are capable of being separated into a high-grade ilmenite and a low titanium magnetite. The metal is used in several different alloys with iron, copper and aluminum and for green and white paint pigments, the only colors of titanium pigments now in common use. It is also used in dyes, rubber, as a porcelain glaze, in glass, and cement made from high-titanium iron slags. This cement is resistant to the action of acids. The market price of titanium minerals varies as to the titanium oxide it contains. Rutile 96% TiO (a) lU to 13^ a pound, ilmenite 52 to 60%; TiO @ $10 to $15 a ton, and ilmenite 32 to 35 7o TiO @ $7 to $8 a ton, all prices Atlantic seaboard. TUNGSTEN BiUiography: Reports XV, XVII, XVIII, XXII. Bulletins 38, 67, 91, 95. . U. S. G. S. Bull. 652. Proc. Colo. Sci. Soc. Vol. XL South Dakota School of IMines, Bulletin No. 12. Eng. and Min. Jour.-Press, Vol. 113, pp. 666-669, Apr. 22, 1922. The commercial production of tungsten ores and concentrates in California began in 1905 ; and has been continuous since, with the exception of 1920-1922 (inclusive), when the mines were shut down owing to low prices due to excess stocks following the war and to lack of tariff protection against foreign importations. Production was resumed on a small scale late in 1923, and is now at practically its pre-war average annual tonnage, though the 1927 figures are less than those for 1926. The material shipped in 1927 included both high-grade sorted ore and concentrates, coming from a property in San Bernardino County. Prices during 1927 ranged from $10.25 to $11.75 per unit, duty paid, for Chinese wolframite, with domestic scheelite $10 to $11. Pres- ent prices are approximately the same. Tungsten ore has been produced in California principally in the Atolia-Randsburg district in San Bernardino and Kern counties, fol- lowed by the Bishop district in Inyo County, with small amounts coming from Nevada County and from the district near Goffs, in eastern San Bernardino. Most of the California tungsten ore is scheelite (cal- 62 MINERAL INDUSTRY OF CALIFORNIA cium tungstate), though wolframite (iron-manganese tungstate) and hiibernite (manganese tungstate) also occur. The deposits at Atolia are the largest and most productive scheelite deposits known/ and the output has in some years equaled or exceeded that of ferberite (iron tungstate) from Boulder County, Colorado. It is interesting in this connection to note that, in practically all other tungsten producing districts of the world, wolframite is the important constituent. Imports of foreign tungsten ore and alloys into the United States during 1927 amounted to 1,613,616 pounds valued at $308,106, com- pared with 3,441,975 pounds valued at $871,294 in 1926, and 10,362 long tons of ore valued at $11,409,237 in 1918, which ores were duty free up to September 22, 1922. Owing to lack of protection against the cheap coolie labor of Asiatic tungsten mines, and low market prices, practically all of the tungsten mines in the United States were closed down from the middle of 1919 to the latter part of 1923. Quotations during 1922 ranged around $2.50 per unit, up to September. The Tariff Act of 1922 placed a duty on tungsten ore or concentrates of 45^ per pound on tlie metallic tungsten contained therein. Duties are also X)rovided for imported tungsten-bearing alloys. Most of the imported ore is coming from Cliina, with smaller amounts from Malaya and Bolivia. Uses. The metal, tungsten, is used mainly in the steel industry and in the manufacture of electrical appliances, including the well-known tung- sten filament lamps. Because of its resistance to corrosion by acids, it is valuable in making certain forms of chemical apparatus. Its employ- ment in tool-steel alloys permits the operation of cutting tools, such as in lathe work, at a speed and temperature at which carbon steel would lose its temper — hence the name 'high speed' steels for these tungsten alloys. As made in the United States, tungsten forms 13% to 20% of such steels. Some chromium, nickel, cobalt, or vanadium are sometimes also included. Tungsten compounds are used in the manufacture of colors. The indicated consumption is approximately 5000 tons of 60% concentrates per year, in the United States. Tungsten is introduced into the molten steel charge, either as the powdered metal or as ferro-tungsten (containing 50%-85% tungsten). The specific gravity of the pure metal, 19.3-21.4, is exceeded only by platinum, 21.5; iridium, 22.4; and osmium, 22.5. Its melting point is 3267° C. (5913° F.), being higher than any other known metal. Though millions of tungsten filament lamps are now made, the wires are so fine that the metal they contain represents but a few tons of tungsten concentrates annually. , j Total Tungsten Ore Production of California.

No commercial production of vanadium has yet been made in Cali- fornia. Occurrences of this metal have been found at Camp Signal, near Goffs, in San Bernardino County, and two companies at one time did considerable development work in the endeavor to open up paying quantities. Each had a mill under construction in 1916, but apparently no commercial output was made. Ore carrying the mineral cuprodes- cloizite and reported as assaying 4% VaOg was opened up. Some ore carrying lead vanadate has been developed in the 29 Palms, or Washing- ton district, on the line between Riverside and San Bernardino counties, but no shipments reported. The principal use of vanadium is as an alloy in steels, especially in tool steel, and in those varieties where resistance to repeated strains is required. Present New York quotations for ferrovanadium are, per pound of vanadium, f. o. b. works, $3.15-$3.65, depending on the grade. ZINC Bibliography: State Mineralogist Reports XIV, XV, XVII, XVIII, XX, XXII, XXIII. Bulletins 38, 67, 91. The recoverable zinc mined in California in 1927 amounted to 8,625,004 pounds valued at $552,000 compared with 20,447,559 pounds and $1,533,568 in 1926. This production came from Shasta, Los Angeles (Santa Catalina Island) and Riverside counties and was shipped in the form of concentrates and sinter to Belgium, though a small amount is used in the manufacture of oxide. The average price per pound quoted for the metal in 1927 was 6.4^ as against 7.5^- in 1926. The zinc ores of Shasta and Calaveras counties are associated with copper, while those of Inyo, Los Angeles and San Bernardino are asso- ciated principally with lead-silver and zinc-silver ores. The principal uses of zinc are for 'galvanizing' (plating on iron to prevent rust), for zinc oxide (used in rubber goods and paint), and for brass (an alloy of copper and zinc). These outlets for the metal take approximately 80% of the quantity produced. Of the remaining 20% 64 MINERAL INDUSTRY OF CALIFORNIA a large portion is rolled into plates and sheets, and utilized in the building industrj^ for sheathing, roofing, leaders, and eaves-troughs. Zinc is particularly desirable and efficient for roofing and siding where corrosive gases are present, as at smelters, refineries and chemical plants. Zinc Production of the United States. The production of slab zinc ^ at reduction plants in the United States in 1927 amounted to 576,960 short tons valued at $73,966,000, not including 15,556 tons of primary metal made from foreign ores, mostly from Mexico, and reduced in refineries in this country. The 1927 production was a decline from that of 1926 of 82,261 tons. 21 20 19 18 17 -Range ^^^CJORKU) 16 15 14 13 12 11 ^ ■ Average Prices or" SLAB ZINC PrimeWsstem Brt>no(3 at St. Louis, Mo Cents per Pound 1927 From Engineering and Mining Journal, July 14, 1928.

As indicated by this subdivision heading, the mineral substances herein considered are those more or less directly used in building and structural work. California is independent, so far as these are con- cerned, and almost any reasonable construction can be made with mate- rials produced in the state. This branch of the mineral industry for 1927 was valued at $54,861,649 as compared with a total value of $54,250,571 for the year 1926, the increase being due to cement, granite and sandstone in spite of a considerable decrease in miscellaneous stone, brick, and magnesite. Deposits of granite, marble and. other building stones are distributed widely throughout this state, and transportation and other facilities are gradually being extended so that the growing demand may be met. The largest single item, cement, has had an interesting record of growth since the inception of the industry in California about 1891. Not until 1904 did the annual value of cement produced reach the million-dollar mark, following which it increased 500% in nine years; though from 1914 to 1918 there was a falling off common to all building materials. The 1927 output established a new record both in quantity and total value, exceeding the previous total value record made in 1923 by over a million dollars. Crushed rock production is yearly becoming more worthy of con- sideration, due to the strides taken in the use of concrete, as well as to activity in the building of good roads. Brick, with an average annual output for a number of years worth approximately $2,000,000, had difficulty in holding its own, due to the popularity of cement and con- crete. In 1920, however, the sales increased to nearly double the previous record figure of the year 1907, and in 1923 showed advances to new figures, with a slight recession in 1924-1927. This item will, no doubt, continue to be an important one, and a market for fire and fancy brick of all kinds will unquestionably never be lacking. All fifty-eight counties contributed to this structural total for 1926. There is not a county in the state which is not capable of some output of at least one of the materials under this classification. During 1927 building construction on the Pacific coast ^ has declined in the large cities and increased in the smaller towns. The twenty principal cities show a falling off' of 20 per cent in the total of building permits. The following summary shows the value of the structural materials produced in California during the years 1926-1927, with increases or decreases in each instance. 'Pacific Coast Letter, Amer.

ASPHALT Bibliography : State Mineralogist Reports VII, X, XII-XV (inc.), XVII, XVIII. Bulletins 16, 32, 63, 67, 69, 91. Asphalt was for a number of years accounted for in the statistical reports by the State Mining Bureau, because in the early days of the oil industry, considerable asphalt was produced from outcroppings of oil sand, and was a separate industrj'^ from the production of oil itself. However, at the present time most of the asphalt comes from the oil refineries, which produce a better and more uniform grade ; hence, its value is not now included in the mineral total, as to do so would be in part a duplication of the crude petroleum figures. Such natural asphalt as is at present mined is in the form of bituminous sandstones, and is recorded under that designation. BITUMINOUS ROCK Bibliography : State Mineralogist Reports XII, XIII, XV, XVII, XVIII, XXI, XXII. This material is essentially an uncemented sandstone which is satur- ated with and held together by a natural asphaltic constituent, probably the residue from the evaporation of a crude petroleum deposit. Bitu- minous rock is still used to a limited extent for road dressing in those districts adjacent to available deposits, though the manufacture of asphalt at the oil refineries has almost entirely superseded the direct use of the native material. The present operators of the quarry near the old City Street Improvement Company's property in Santa Cruz County advise that they are now putting on the market a material which can be laid cold. It will be especially applicable and valuable for patching jobs. Shipments from quarries in Santa Barbara and Santa Cruz counties in 1927 totaled 3515 tons of bituminous rock, valued at $17,704 f . o b. rail-shipping point.

Bricks of many varieties and in important quantities are annually produced in California, as might be expected in a state with such diver- sified and widespread mineral resources. The varieties include com- mon, fire, pressed, glazed, enamel, fancy, vitrified, sand-lime, and others. Not only do the plants here supply practically all of our own require- ments in these products, but considerable quantities are shipped to contiguous territory and certain products are shipped over a much wider radius. So far as possible, the different kinds have been segre- gated in the tabulation herewith accompanying. "We also include under this heading the various forms of hollow building 'tile' or blocks. The application of these tile to residence construction as well as to other structures is growing; though their total for 1927 shows a drop from the figures of 1926. The aggregate value of all kinds of brick in 1927 shows a decrease of approximately 7 per cent from that of 1926, to which each of the groups contributed. Bulletin No. 99, "The Clay Resources and the Ceramic Industry of California," published this year (1928) covers all the brick plants throughout the state, giving a detailed description of each.

Bulletin 38. Lime to the amount of 60,498 tons, valued at $631,497, was produced by nine plants in seven counties during 1927, as compared with 63,568 tons, valued at $670,837, in 1926. There were two plants each in San Bernardino and Santa Cruz counties, and one each in Inyo, Kern, Plumas, Tulare, and Tuolumne. So far as we have been able to segregate the data, these figures include mainly only such lime as is used in building operations ; though they do include a small proportion of calcined lime employed in agriculture and the chemical industries, the figures for which were not separable. A portion is hydrated lime. Limestone utilized in sugar making, for smelter flux, as a fertilizer, and other special industrial uses, are classi- fied under 'Industrial Materials.' That consumed in cement manufac- ture is included in the value of cement. Lime Production of California, by Years.

A Preliminary Statement of Information," May 19, 1926. The production of magnesite in California during 1927 amounted to a total of 46,093 tons of crude ore, valued at $577,887. Only a small part of it was sold 'crude,' however, as it is practically all shipped in the calcined form. The reports at hand shoAv a total of 19,277 tons shipped calcined, including a small tonnage dead-burned for refractory purposes, the balance going to the plastic trade. From 2 to 2^ tons of crude material are mined to make one ton of calcined. The 1927 output is a decrease both in quantity and value from the 1926 figures of 50,915 tons crude valued at $587,642. The average of the values reported for 1927 is $12.50 per ton compared with $11.60 in 1926. There were two operators who produced 1300 tons of crude but who had not shipped any during 1927 though they expect to do so in 1928. Occurrence. Magnesite is a natural carbonate of magnesium, and when pure con- tains 52.4% COo (carbon dioxide), and 47.6% MgO (magnesia). It has a hardness of 3.5 to 4.5, and specific gravity of 3 to 3.12. It is both harder and heavier than calcite (calcium carbonate), and also contains a higher percentage of CO2 as calcite has but 44%. Most of the Californian magnesite is comparatively pure, and is ordi- narily a beautiful, white, fine-grained rock with a conchoidal fracture resembling a break in porcelain. The Grecian magnesite is largely of this character ; but the Austrian varieties usually contain iron, so that they become brown after calcining. The Washington magnesite resem- 78 MINERAL INDUSTRY OP CALIFORNIA bles dolomite and some crystalline limestones in physical appearance. Its color varies through light to dark gray, and pink. In California the known deposits are mostly in the metamorphic rocks of the Coast Ranges and the Sierra Nevada, being associated with serpentine areas. The notable exceptions are the sedimentary deposits, at Bissell in Kern County and at Afton in San Bernardino County. Several thousand tons have been shipped from the Bissell deposit ; and small shipments have been made from the Afton property. The Washington deposits are associated with extensive strata of dolomite limestone. The magnesite there appears to contain more iron than most of the California mineral, which makes it desirable for the steel operators. However, recent experience has proved that several California localities have sufficient iron in their magnesite to be service- able in the steel furnaces. Uses. The principal uses include : Refractory linings for basic open-hearth steel furnaces, copper reverberatories and converters, bullion and other metallurgical furnaces ; in the manufacture of paper from wood plup ; and in structural work, for exterior stucco, for flooring, wainscoting, tiling, sanitary kitchen and hospital finishing, etc. In connection with building work it has proved particularly efficient as a flooring for steel railroad coaches, on account of having greater elasticity and resilience than 'Portland' cement. For refractory purposes the magnesite is 'dead-burned' — i. e., all or practically all of the COj is expelled from it. For cement purposes it is left 'caustic' — i. e., from 2% to 10% of COo is retained. When dry caustic magn&site is mixed with a solution of magnesium chloride (MgCl,) in proper proportions, a very strong | cement is produced, known as oxychloride or Sorel cement. It isj applied in a plastic form, which sets in a few hours, as a tough, seamless surface. It has also a very strong bonding power, and will hold firmb to wood, metal, or concrete as a base. It may be finished with a verj smooth, even surface, which will take a good wax or oil polish. As ordinarily mixed there is added a certain proportion of wood flourJ cork, asbestos, or other filler, thereby adding to the elastic properties of the finished product. Its surface is described as 'warm' and 'quiet] as a result of the elastic and nonconducting character of the composite material. The cement is frequently colored by the addition of some mineral pigment to the materials before mixing as cement. For refractory purposes the calcined magnesite is largely made uj into bricks similar to fire-brick for furnace linings. It is also usee unconsolidated, as 'grain' magnesite. For such, an iron content \i desirable, as it allows a slight sintering in forming the brick. Dead-j burned, pure magnesia can not be sintered except at very high temperaj tures ; and it has little or no plasticity, so that it is hard to handle. It^ plasticity is said to be improved by using with it some partly calcinee or caustic magnesite. Heavy pressure will bind the material sufficiently to allow it to be sintered. A coating of crushed magnesite is laid on hearths used for heating steel stock for rolling, to prevent the scale formed from attacking th^ fire-brick of the hearth. STATISTICS OF ANNUAL PRODUCTION 79 Before the World War, practically all of the domestic output of caustic magnesite was used in the manufacture of pulp and paper. For this purpose calcined dolomite is now used. The use of dolomite instead of magnesite by paper manufacturers began during the war when the price of magnesite was very high. Dolomite was found to be a good substitute for magnesite in the bisulphite process of paper making and so its use has continued. Fmports. The Tariff Act of 1922, which became effective September 22d, of that year, placed the following import duties on magnesite : Crude magnesite %6^ per lb., caustic-calcined magnesite %^ per lb. ; dead- burned and grain magnesite, not suitable for manufacture into oxy- chloride cements, -%of^ V^^ lb. ; magnesite brick, %fS per lb. and 10% ad valorem. The figures of imports for 1927, as published by the U. S. Bureau of Foreign and Domestic Commerce, show a total of 60,224 short tons of calcined ore, valued at $959,483, as compared with 92,546 tons and $1,415,509 in 1926. Total Magnesite Production of California. The first commercial production of magnesite in California was made in the latter part of 1886 from the Cedar Mountain district,^ southeast of Livermore, Alameda County. Shipments amounting to 'several tons' or 'several carloads' were sent by rail to New York; but there is apparently no exact record of the amount for that first year. The statistical records of the State Mining Bureau began with the year 1887, and the table herewith shows the figures for amount and value, annually, from that time. Shipments of magnesite from Napa County began in 1891 from the Snowflake Mine; from the Red Mountain deposits in Santa Clara County, in 1899; and from Tulare County in 1900.

An unlimited amount of high-grade sandstone is available in Cali- fornia, but the wide use of concrete in buildings of every character, as well as the popularity of a lighter-colored building stone, has curtailed production in this branch of the mineral industry during recent years almost to the vanishing point. In 1927 a total of 22,900 cu. ft., valued at $205,400, was quarried in five counties, Monterey, Napa, Santa Barbara, Siskiyou and Sonoma; compared with 34,100 cu. ft. and $17,500 in 1926. The material reported from Monterey County is in reality an indurated shale of the Monterey series, of a cream color and utilized as a building stone ; and that from Sonoma is a stratified, altered andesite having the appearance of sandstone. A large portion of the sandstone was sold for landscape work and used as stepping stones for walks and for fountains, walls, etc. Sandstone Production of California, by Years.

Bulletin 38. U. S. Geol. Surv., Bull. 586. U. S. Bur. of Mines, Bull. 218. Slate was first produced in California in 1889. Up to and including 1910 such production was continuous, but since then it has been irregu- lar. Large deposits of excellent quality are known in the state, espe- cially in El Dorado, Calaveras and Mariposa counties, but the demand has been light owing principally to competition of cheaper roofing materials. 'Slate' is a term applied to a fine-grained rock that has a more or less perfect cleavage, permitting it to be readily split into thin, smooth sheets. Varieties differ widely in color and have a considerable range in chemical and mineralogical composition. Excepting certain rare slates of igneous origin (of which the green slate of the Eureka quarry. El Dorado County, California, is an example) formed from volcanic ash or igneous dikes, slates have originated from sedimentary deposits consisting largely of clay. By consolidation, and the pressure of super- imposed materials, clays become bedded deposits of shale. By further consolidation under intense pressure and high temperature incident to mountain-building forces, shales are metamorphosed to slates. The principal mineral constituents are mica, quartz, and chlorite, with smaller varying amounts of hematite, rutile, kaolin, graphite, feldspar, tourmaline, calcite, and others. The color of slate is of economic importance. The common colors are gray, bluish gray, and black, though reds and various shades of green are occasionally found. The permanency of slate for roofing is well known. It is stated that there are slate roofs in Pennsylvania and Maryland over 100 years old. ^ "In Engrland and Wales, and in France, many buildings constructed in the 15th and 16th centuries were roofed with slate, and the roofs are still in excellent condi- tion. There is a record of a chapel in Bedford-on-Avon in Wiltshire, England, roofed with slate in the 8th century, and after 1200 years of climatic exopsure is moss- covered but in good condition." Contrary to the general impression, however, the major portion of the slate produced in the United States is used on the inside rather than the outside of buildings. Its interior uses include stationary washtubs, electrical switchboards, and blackboards. A square of roofing slate is a sufficient number of pieces of any size to cover 100 square feet of roof, with allowance generally for a three- inch lap. The sizes of the pieces of slate making up a square range from 7x9 inches to 16 x 24 inches, and the number of pieces in a square ranges from 85 to 686. The Ferry Building, San Francisco, is roofed with Eureka slate from El Dorado County. In California there were shipments in 1927 amounting to 2686 tons valued at $17,960 from El Dorado, Mariposa and Tuolumne counties. This was an increase over the 1926 output valued at $7,371. Most of this slate was crushed and used for roofing granules. 1 Bowles, O., Slate as a Permanent Roofing Material : U. S. Bur. of M., Reports of Investigations, Serial No. 2267, July, 1921, p. 4.

'Miscellaneous stone' is the name used throughout this report as the title for that branch of the mineral industry covering crushed rock of all kinds, paving blocks, sand and gravel, and pebbles for grinding mills. The foregoing are very closely related from the standpoint of the producer; therefore it has been found to be most satisfactory to group these items as has been done in recent reports of this Bureau. So far as it has been possible to do so, crushed rock production has been subdivided into the various uses to which the product was put. It will be noted, however, a very large percentage of the output has been tabulated under the heading 'Unclassified.' This is necessary because of the fact that many of the producers have no way of telling to what specific use their rock was put (or at least the proportions to each use) after they have quarried and sold the same to distributors and con- tractors. In addition to amounts produced by commercial firms, both corpo- rations and individuals, there is hardly a county in the state but uses more or less gravel and broken rock on its roads. Of much of this, particularly in the country districts, there is no definite record kept. For the year 1927 the production of crushed rock registered a gain both in tonnage and value over the preceding year. Sand and gravel tonnage remained practically the same, although there was a drop in their value. This resulted in a total value of $18,911,194, being a- decrease from $19,859,873 in 1926. . As for some years past, Los Angeles County led all others by a wide margin with an output valued at $6,292,078 (compared with $7,472,- 884 in 1926); followed by Alameda, second, with $1,538,017; River- 84 MINERAL INDUSTRY OF CALIFORNIA side, third, with $1,244,043; Fresno, fourth, with $1,118,761; San Diego, fifth, with $889,642 ; Contra Costa, sixth, with $816,140 ; Sacra- mento, seventh, with $754,206; Humboldt, eighth, with $554,963; fol- lowed in turn by Santa Clara, Ventura, Marin, San Benito, Orange, San Bernardino, Stanislaus, Monterey. Paving Blocks. The paving block industry has decreased materially of recent years,! practically to the vanishing point, because of the increased construction" of smoother pavements demanded by motor vehicle traffic. The blocks made in Solano County were of basalt ; those from Sonoma are of basalt, andesite, and some trachyte, while those from Madera, Placer, River- side, San Bernardino, and San Diego are of granite.

Grinding Mill Pebbles. Production of pebbles for tube and grinding mills began commer- cially in California in 1915. Owing to the decreased imports and higher prices of Belgium and other European flint pebbles, due to the war, there was a serious inquiry for domestic sources of supply. In 1916 and 1917 shipments totaled in excess of 20,000 tons per year; but they have since dropped to an insignificant figure. San Diego County has been the principal contributor, with some also from Fresno and Sacramento. Shipments have been made to metallurgical plants in California, Nevada, Montana and Utah. Imports in 1927 amounted to 13,563 long tons, valued at $93,658 compared with 13,474 long tons and $120,078 in 1926. California output for 1927 was 288 tons, valued at $1,800, an increase from the 1926 figures.

A considerable part of the gravel excavated is passed through grading and washing plants, and the material over 2 inches in size is crushed. Much of it is utilized in concrete mixtures. Most of the gravel used for road surfacing and repairs as well as that for railroad ballast is creek- run or pit-run material which is spread upon the roads without under- going any grading or washing.

This item is each year assuming a more important position in the commercial mineral list of California. The 1926 figures totaled 46,601 tons and $105,336. Crushed Rock. To list the kinds and varieties of rock utilized commercially under this heading would be to run almost the entire gamut of the classifica- tion scale. Much depends on the kind available in a given district. Those which give the most satisfactory service are the basalts and other hard, dense, igneous rocks which break with sharp, clean edges. In many localities, river-wash boulders form an important source of such material. In such cases, combined crushing and washing plants obtain varying amounts of sand and gravel along with the crushed sizes. In Sacramento and Butte counties the tailings piles from the gold dredgers are the basis of like operations. The values given are based on the selling prices, f . o. b. cars, barges, or trucks, at the quarry. Miscellaneous Stone Production of California, by Years.

The following mineral substances have been arbitrarily arranged under the general heading of 'Industrial Materials,' as distinguished from those which have a clearly defined classification, such as metals, salines, structural materials, etc. These materials, many of which are mineral earths, are, with four or five exceptions, as yet produced on a comparatively small scale. The possibilities of development along several of these lines are large, and Avitli increasing transportation and other facilities, together with stead- ily growing demands, the future for this branch of the mineral industry in California is promising. There is scarcely a county in the state but might contribute to the output. Up to within the last few years, at least, production has been in the majority of instances dependent upon more or less of a strictly local market, and the annual tables show the results of such a condition, not only in the widely-varying amounts of a certain material produced from year to year, but in widely-varying prices of the same material. The more important of these minerals thus far exploited, so far as shown by value of the output, are limestone, mineral water, pyrites, pottery clays, diatomaceous earth, gj^psum, talc, dolomite, fuller's earth. This gToup as a whole showed an increase in the total value to $5,258,068 in 1927 from $4,675,924 for 1926.

Asbestology, Vol. 5, No. 7, July, 1927. In 1927 there was a small tonnage of crude asbestos ore and fibre produced in California, but as there was only a single operator, the figures are concealed under the 'Unapportioned' item. The future of asbestos mining in California is dependent largely upon the development of uses in quantity for the short-fibre mill grades, and for the amphibole variety. There are apparently large resources of such material that can be made available. Some spinning- grade fibre has also been found in this state, notably in Nevada, Cala- veras, and Monterey counties, but the commercial yield to date has been small. There are extensive serpentine areas in the Coast Ranges, in the Klamath Mountains, and in several sections of the Sierra Nevada which are within the range of possible asbestos producers, as chrysotile is a fibrous form of serpentine. These localities all yielded chromite in greater or less amounts during the World War period. Three-quarters of the world's supply of asbestos was for many years produced by Canada. At present, Rhodesia furnishes 60 per cent of the long fibre, though Canada in addition to its long fibre still accounts for practically the entire output of lower grades.

The 1927 yield came from properties in Mariposa, Nevada and Orange counties. The bar^'tes from Mariposa and Nevada counties was consumed principally in the manufacture of lithopone. That from Orange County was a furnace sinter, being a barytes gangue in a quiclcsilver ore, and was sold for use in oil-well drilling mud. More than half of the total tonnage of barytes utilized in the United States is taken in the manufacture of lithophone, which is a chemically- prepared white pigment containing approximately 70% barium sulphate and 30% zinc sulphide. This is one of the principal constituents of 'flat' wall paints. Other important uses for barytes, after washing and grinding, are as an inert pigment and filler in paint, paper, lino- leums, oilcloth and rubber manufacture, and in the preparation of a number of chemicals including barium binoxide, carbonate, chloride, nitrate, and the sulphate precipitated, or 'blanc fixe.' Present quotations for barytes vary from $7 to $9 per ton, crude, f. 0. b. rail-shipping point, depending on quality. Most baryte has to be washed and acid treated to remove iron stains or other impurities before being suitable for paint use. Known occurrences of this mineral in California are located in Inyo, Los Angeles, Mariposa, Monterey, Nevada, San Bernardino, Shasta and Santa Barbara counties. The deposit at El Portal, in Mariposa County, has given the largest commercial production to date, in part witherite (barium carbonate, BaCOg). Witherite has also been found in Shasta County, but no shipments have yet been made from the deposit. Total Barytes Production of California. The first recorded production of barytes in California, according to the statistical reports of the State Mining Bureau, was in 1910.

Infusorial and diatomaceous earths — sometimes called tripolite — are very light and extremely porous, chalk-like materials composed of pure silica (chalk, being calcareous) which have been laid down under water and consist of the remains of microscopical infusoria and diatoms. The former are animal remains, and the latter are from plants. The principal commercial use of diatomaceous earth (also called 'diatomite') is as an absorbent. It is also employed in the manufacture of scouring soap and polishing powders; for filtration purposes; in making some classes of refractory brick ; and as an insulating medium both in heat- ing and refrigeration. It is a first-class nonconductor of heat, where high temperatures are employed, such as around steel and gas plants and power houses. In such cases, it is built in as an insulating layer in furnace walls. In Germany, under the name ' kieselguhr, ' it was used as an absorbent for nitroglycerine in the early manufacture of dynamite. As a nonconductor of heat it has been used alone or with other mate- rials as a covering for boilers, steam pipes and safes, and in fireproof cement. It is used largely by paint manufacturers as a wood filler. Boiled with shellac it is made into records for talking machines. It has been used for absorbing liquid manures so that they could be utilized as fertilizers, and as a source of silica in making water-glass as well as in the manufacture of cement, tile glazing, artificial stone, ultramarine and other pigments of aniline and alizarine colors, paper filling, sealing wax, fireworks, hard-rubber objects, matches, and paper mache, and 96 MINERAL INDUSTRY OF CALIFORNIA for solidifying bromine. For making insulating brick the material is sawed into blocks, and for all other purposes it is ground and screened. The most important deposits in California thus far known are located in Monterey, Orange, San Luis Obispo, and Santa Barbara counties. The Santa Barbara material is diatomaceous and is of a superior quality, particularly for filtration uses which bring the higher prices. Infusorial or diatomaceous earths are also found in Fresno, Kern, Los Angeles, Plumas, San Benito, San Bernardino, San Joaquin, Shasta, Sonoma, and Tehama counties. As almost 90% of the output in California is from a single operator, we have concealed the exact figures under the 'Unapportioned' item in the state and county totals. There were six operators in 1927 in Los Angeles, Monterey, Santa Barbara and Shasta counties, the ship- ments showing a decrease in tonnage and value compared with 1926, The material shipped was utilized for insulation, filtration, paint pigment, cement admixture, and for clarification of gasoline and kerosene.

BORATES Bibliography : State Mineralogist Reports III, X, XII-XV (inc.), XVil-XXIII (inc.). Bulletins 24, 67, 91. During 1927 there was produced in California a total of 89,093 tons of borate materials compared with 84,101 tons for the year 1926. The material shipped during the year included crude and select colemanite ore from Inyo County, the new sodium borates, kernite (Rasorite) and kramerite from Kern County ; also crystallized borax prepared by evaporation of brines at Searles Lake in San Bernardino County. As the crude ore is not sold as such, but is almost entirely calcined before shipping to the refinery for conversion into the borax of com- merce, and because of the fact that the material varied widely in boric acid content, we have recalculated the tonnage to a basis of 40% A.B.A. This is approximately the average A.B.A. content of the colemanite material after calcining, and also of the crystallized borax obtained from evaporation of the lake brines. Recalculated as above, the 1927 production totals 72,462 tons, valued at $3,043,260, an increase over the similar figures for 1926, which were 47,605 tons and $1,625,298. 118 MINERAL INDUSTRY OF CALIFORNIA Colemanite is a calcium borate, and the material mined is shipped to seaboard chemical plants for refining. The latest development in the borax industry is the finding in quantity and opening up of a new borate mineral which bids fair to supplant colemanite in much the same way that the colemanite deposits displaced the borax industry in the desert playas or dry lakes, some forty years ago. This new mineral is 'kernite' (or 'rasorite'), a sodium borate with a smaller water-of- crystallization content than the 'borax' of commerce, so that when re-crystallized to borax, the resulting product has an increased weight over the original material. These deposits are being opened up by the Pacific Coast Borax Company in southeastern Kern County. Refined 'borax' (sodium tetraborate) is used in making the enameled coating for cast-iron and steelware employed in plumbing fixtures, chemical equipment, and kitchen utensils. It is also a constituent of borosilicate glasses which are utilized in making lamp chimneys, baking dishes, and laboratory glassware. Other important uses of borax are in the manufacture of laundry and kitchen soaps, in starch, paper siz- ing, tanning, welding, and in the preparation of boric acid, which is employed as an antiseptic and in preserving meats. Among the newer uses for borax is its employment in the preserving of citrus fruits by washing them in a solution of borax, which closes the pores of the skin. The application of this process is increasing in California and Florida. Another is as a preservative of wood, in addition to which borax, being non-inflammable, renders it fireproof. An increased foreign demand stimulated an increased production of this material. The total amount exi^orted from the United States was 36,954 short tons valued at $2,422,144 compared with 14,305 short tons valued at $1,256,798 in 1926. From one California port in 1927 approximately 22,000 short tons of borax was shipped to the United Kingdom and continental Europe. California deposits are the most important source of borax in the world, and that this material can be mined and refined at a low cost, sup])lying an increasing market, is shown in the following article taken from the Engineering and Mining Journal :^ "New aspects in the present situation of the borax industry have been disclosed by an authority as the result of the recent development of important new deposits of borate minerals in the Kramer district in southeast Kern County, California. "The new mine that has been opened by the Pacific Coast Borax Company in the northwest corner of Sec. 24, T. 11 N., R. S W., and the extreme northwest corner of Sec. 19 of the township next adjoining on the east, is apparently now on regnlar. production, with railroad connections established and shipping the new kernite ore in large quantities. The present output of borate ores or products in the United States is approximately as follows : Pacific Coast Borax Co. mine near Kramer, Average dail}/ shipment Cal. 200 tons crude kernite ore of high purity American Trona Corp., Searles Lake, Cal. 140 tons refined borax West End Chemical Co. mine near Las Vegas. Nev. 2.5 tons calcined colemanite West End Chemical Co. plant at Searles Lake, Cal. 1.5 tons refined borax Total daily production 3 SO tons "The total production represented by these averages, if they are maintained throughout this year, will be approximately 140,000 tons of borax for 1928, which is probably approximately the amount of present market requirements. "The new source of borate mineral at Kramer is probably the most available source of borax that the world has ever known, in quality of material, massiveness, purity, minability of the deposit, and accessibility. The new mineral kernite appar- ently exists under extremely favorable mining conditions, so that the ore can appar- ently be brought to the surface at a cost of less than $10 a ton. It may be recalled that the kernite ore recovered in such pure form as indicated by the present opera- tions should yield more than its equivalent in weight of commercial borax, and that 1 Engineering and Mining Journal, Mar. 31, 1928, p. 551. STATISTICS OP ANNUAL PRODUCTION 119 only the simplest refining processes are required to transform the crude material as mined into the commercial product. Therefore it is entirely likely that the cost of borax may be cut from recent quotations, which have ranged around four cents a pound, to one-half that amount or even less. "Another interestin.e; factor may also have an important Influence in the produc- tion situation and marketing of this product. It appears that an important exten- sion of the ricliest part of these deposits lies south of the property now being oper- ated and this new deposit is evidently under independent contn)l. The discovery was made by borings and is situated about tliree-fiuarters of a mile southwest of the • original" sliaft in the northeast corner of Sec. 24. According to authentic informa- tion these borax deposits revealed a thick section of particularly pure kernite in the new' area referred to, and a mining shaft is being rapidly sunk to develop this new deposit. The material which may ))e developed from this independent operation promises to exert an important intluence with tlie Kramer district." Total Production of Borate Materials in California. Borax was first discovered in California in the waters of Tuscan Springs in Tehama County, January 8, 1856. Borax Lake in Lake County was discovered in September of the same year by Dr. John A. Veach. This deposit was worked in 1864-1868, inclusive, and during that time produced 1,181,365 pounds of refined borax. The bulk of it was exported by sea, to New York. This was the first commercial output of this salt in the United States, and California is still today the leading American producer of borax, having been for many years the sole producer. Production from the dry lake 'playa' deposits of Inyo and San Bernardino counties began in 1873 ; but it was not until 1887 that the borax industry was revolutionized by the discovery of the colemanite beds at Calico, in San Bernardino County, and later similar beds in Inyo and Los Angeles counties.

This same plant has been recovering magnesium chloride for a number of years. A small amount of bromine was also reported made at the similar bittern-water plant of the Industrial Chemical Company at Newark, Alameda County. The amounts and values of this first and second years' yields of bromine in California are concealed under the 'Unapportioned' item. A large part of the bromine output of the United States is not sold as bromine, but in the form of potassium and sodium bromides and other salts. The principal production in the United States has come from bitterns from salt wells in Michigan, Ohio and West Virginia. The best known uses of bromine are its application in the form of silver bromide in photography and the manufacture of ethyl gasoline. Bromine, as such, was used extensively in the European War in making asphyxiating gases. It also has some uses in medicine, particularly in the treatment of nervous diseases.

'How to Maintain Roads,' manual of instruction of Dow Chemical Company. Calcium chloride is hygroscopic, that is, it has an affinity for water. This property is taken advantage of by utilizing this salt as a drying agent. It is also sprinkled on dirt roads and playgrounds to keep down dust by absorbing moisture. In refrigerating machinery for ice fac- tories, meat-packing houses and cold-storage warehouses, a calcium- chloride solution is stated to have some advantages over salt brine. In fire buckets this solution has an advantage over pure water, in that it has a lower freezing point, does not corrode metal, and tends to keep the buckets full due to its absorbing moisture from the atmosphere. Powdered calcium chloride is used in drying gases, fruits and vege- tables. Total Calcium Chloride Production of California. Commercial production of calcium chloride in California was first reported to the State Mining Bureau in 1921, from two plants in San Bernardino County, being obtained as a by-product in the refining of salt from deposits in certain of the desert dry lakes. In 1922-1924, there was only a single operator, so that the annual details are concealed under the 'unapportioned' item.

S. The 1927 production of magnesium salts in California is concealed under 'unapportioned.' This was nearly all chloride, sold for use in magnesite stucco and cement mixtures (Sorel cement), also some for 'road liquor.' It was in part marketed in the liquid form testing 34°-36° Baume, and in part as dry crystals, and was prepared from residual bitterns at salt plants in Alameda and San Diego counties. The sulphate marketed was utilized for medicinal and bath purposes. "With the use of magnesite cement and stucco coming -more into prom- inence in building construction on the Pacific Coast, the demand for magnesium chloride is increasing here ; but the domestic article has to meet the competition of the cheaper, imported German chloride. The average value reported for the chloride produced in California in 1927 was approximately $19 per ton, f. o. b. plant. Total Production of Magnesium Salts in California. Commercial production of magnesium chloride in California was begun in 1916 by some of the salt companies, from the residual bitterns obtained during the evaporation of sea water for its sodium chloride. In addition, some magnesium sulphate, or 'epsom salts' is also made, annually, but in smaller amount. The total production of magnesium salts in California, since the beginning of the industry here, is shown in the following tabulation : Year Tons Value 1916 851 $6,407 1917 1,064 34,973 1918 1,008 29,955 1919 1,616 82,457 1920 3,150 107,787 1921 4,153 106,140 1922 3,036 89,788 1923 3,662 116,031 1924 4,823 145,883 1925 4,221 132,553 1926 4,881 124,470 1927 * Totals 32,465 $976,444 * Concealed under 'Unapportioned.'

Nitrates of sodium, potassium and calcium have been found in various places in the desert regions of the state, but no deposit of commercial value has been developed as yet. It is hoped that a closer search may some day be rewarded by workable discoveries. At present the princi- pal commercial source of nitrates is the Chilean saltpeter (sodium nitrate) deposits in South America. The fixation of atmospheric nitrogen electrically has been accom- plished successfully in Germany and Scandinavia. The possibilities of cheap hydro-electric power in California make the subject one of 122 MINERAL INDUSTRY OF CALIFORNIA interest to ns, as we have also the natural raw materials and chemicals to go with the power. Sodium and potassium cyanides can be made by fixation of atmospheric nitrogen electrically. POTASH Bibliography: State Mineralogist Reports XV, XVIII, XX, XXII. Bulletins 24, 67, 91. U. S. G.

During 1927, a total of 67,340 tons of potash salts of all grades was produced in California, valued at $1,952,852, compared with 32,884 tons and $812,285 in 1926. This was in part chloride and part from distil- lery slops char. The quality of the product averaged 60% equivalent KoO content; and the material was sold principally for fertilizer manufacture. Imports of crude potash minerals and salts into the United States in 1927, according to the U. S. Bureau of Foreign and Domestic Com- merce, amounted to 623,109 long tons, valued at $13,423,925, compared with 815,715 tons and $14,122,699 in 1926. These materials consisted mainly of 'manure salts,' crude chloride (muriate) and sulphate, and kainite, all of which are admitted duty-free. Quotations have recently ranged from $46 per ton c.i.f. Atlantic and Gulf ports, for high-grade sulphate (90%-95%), to $35 per ton for muriate (80%-85%), and $19 for manure salts (30%). Other uses for potash salts, besides those noted above, are in the manufacture of the best liquid soap and some higher-grade cake soaps, of some finer grades of glass, and in matches. The chemical require- ments include tanning, dyeing, metallurgy, electroplating, photography and medicine. Total Production of Potash in California. Potash production began commercially in California in 1914, with a small yield from kelp. The bulk of the output comes from deposits of potash-bearing residues and brines in the old lake beds of the desert regions, particularly Searles Lake, San Bernardino County. A small amount is made annually from salt-works bitterns, and for a time there was some from Portland cement dust. Some also is obtained from molasses distillery-slops char. The annual amounts and value of these potash materials, since their beginning in California in 1914, are shown by the following table : Year Tons Value 1914 10 $460 1915 1,076 19,391 1916 17,908 663,605 1917 129,022 4,202,889 1918 49,381 6,808,976 1919 28,118 2.415,963 1920 26,298 1,465,463 1921 14,806 390,210 1922 17,776 584,388 1923 29,597 709,836 1924 33.107 747,407 1925 36,355 829,770 1926 32,884 812,285 J927 67,340 l,952,85r Totals 483,078 $21,609,498 STATISTICS OF ANNUAL PRODUCTION 123 SALT Bibliography: State Mineralogist Reports II, XII-XV (inc.), XVII-XXIII (inc.) ; Bulletins 24, 67, 91.

Most of the salt production in California is obtained by evaporating the water of the Pacific Ocean, plants being located on the shores of San Francisco, Monterey, and San Diego bays, and at Long Beach. Additional amounts are derived from lakes and lake beds in the desert regions, mainly in Kern and San Bernardino counties. A small amount of valuable medicinal salts is obtained by evaporation of the water of Lake Mono, Mono County.

There were no shipments of salt cake (sulphate) from the Carrizo Plains, San Luis Obispo County in 1927. The total amounted to 62,571 tons, valued at $1,478,239, beins; a slight decrease in quantity but an increase in value compared with the 1926 figures of 63,333 tons and $1,305,802. The dense ash and bicarbonate were used mainly in the manufacture of soap, glass, sugar refining, and chemicals ; and the trona for metal- lurgical purposes. Sodium compounds to some extent replace potassium compounds, in glass and soap making, in photography, in match making, in tanning, sugar refining, and in the manufacture of cyanide for extracting gold and silver from their ores.

The State of California includes a total area of 158,297 square miles, of which 155,652 square miles are of land. The maximum width is 235 miles, the minimum 148 miles, and the length from the northwest corner to the southeast corner is 775 miles. The state is divided into fifty-eight counties. The 1920 census figures show a total population for California of 3,437,709. A 1927 estimate by the State Controller places the figure that year at 5,398,457. Minerals of commercial value exist in every county, and during 1927 some active production was reported to the State Division of Mines and Mining from all of the fifty-eight. Rank of Counties in Mineral Yield, 1927. Of the first ten counties, in point of total output for 1927, the first four, Los Angeles, Kern, Orange, Ventura, owe their position mainly to petroleum, as does also Fresno (sixth). Los Angeles, due to its oil, leads all the others, being credited with 36% of the entire state's total value for 1927, having passed Kern in 1923, which led for many years. San Bernardino (fifth) owes its place chiefly to cement, silver, potash, borax, mineral water, and tungsten; Riverside (seventh) to cement, stone, brick and tile; Yuba (eighth) to gold; Santa Cruz (ninth) to cement; Plumas (tenth) to copper. Twenty-four counties have each a total in excess of a million dollars in 1927. Cement is an important item in nine of these counties, gold in four, and miscellaneous stone, granite, and soda in one each. In the point of variety and diversity, San Bernardino County led all others in 1927, with a total of 23 differ- ent mineral products on its commercial list, followed by Los Angeles with 20 ; San Diego with 19 ; Kern and Riverside with 17 each ; Inyo with 13 ; Butte, 12 ; Calaveras, Monterey, Santa Barbara and Shasta with 11 each.

Glenn County, standing- forty-seventh, owes its position among the mineral-producing counties of the state mainly to the presence of large deposits of sand and gravel which are annually worked, the product being used for railroad ballast, etc. In 1917 and 1918, chromite was also an important item. In the foothills in the western portion of the county, deposits of chromite, copper, manganese, sandstone, and soap- stone have been found. Commercial production for 1927 was as follows, being an increase from the $58,391 of the previous year: Substance Value Stone, miscellaneous $63,869 HUMBOLDT Land area: 3634 square miles. Population: 37,857 (1920 census). Location: Northwestern portion of state, bordering on Pacific Ocean. Humboldt County is almost entirely mountainous, transportation within its limits being vary largely by auto and wagon road, and trail, and until recent years Avas reached from the outside world by steamer only. The county is rich in mineral resources, among which are brick, chromite, coal, clay, copper, gold, iron, mineral water, natural gas, petroleum, platinum, silver, and miscellaneous stone. Eight mineral substances, as shown by the table giv'tn below, having a total value of $562,802, were produced in 1927, as compared with the 1926 output of $706,670.

INYO Land area: 10,019 square miles. Population: 7031 (1920 census). Location: Lies on eastern border of state, north of San Bernardino County. Inyo, the second largest county in the state, and containing less than one inhabitant per square mile, is extremely interesting from a mineral- ogical point of view. It is noted because of the fact that within its borders are located both the highest point, Mount Whitney (elevation 14,502 feet), and the lowest point. Death Valley (elevation 290 feet below sea level), in the United States. In the higher mountainous sections are found many vein-forming minerals, and in the lake beds of Death Valley saline deposits exist. Inyo's mineral production during the year 1927 reached a value of $2,519,834, standing thirteenth among the counties of the state in this respect. Thirteen different mineral substances were produced.

KERN Land area: 8003 square miles. Popidation: 54,843 (1920 census). Location: South-central portion of state. Kern County, because of its immensely productive oil fields, for many years stood preeminent among all counties of California in the value of 132 MINERAL INDUSTRY OF CALIFORNIA its mineral output, the exact figures for 1927 being $64,729,488. Kern was surpassed by both Los Angeles and Orange counties in 1923, but by Los Angeles, only, in 1924-1927, for which petroleum also is respon- sible. The 1926 mineral output for this county was worth $83,556,074. The decrease was due to a smaller quantity and lower prices of crude oil. During 1927 seventeen different mineral substances were produced. Among the mineral resources, developed and undeveloped, of this section are antimony, asphalt, borax, brick, clay, cement, copper, feld- spar, fuller's earth, gems, gold, gypsum, iron, lead, limestone, magne- site, marble, mineral paint, natural gas, petroleum, potash, pumice, salt, silica, silver, soapstone, soda, sulphur, and tungsten.

ORANGE Land area: 795 square miles. Population: 61,375 (1920 census). Location: Southwestern portion of state, bordering Pacific Ocean. Orange County is one of the many in California which on casual inspection appears to be anytliing but a mineral producing section. It stood for several years, however, as the second county in the state in regard to the total value of mineral output, on account of its highly productive oil fields. It was passed in 1922 by Los Angeles, the credit for which is also due to oil, and in turn Orange passed Kern County in 1923, but dropped back to third in 1924-1926. This county shows a mineral production for 1927 of $60,547,041, compared to the 1926 output, worth $63,223,082, the decrease due to lower petroleum prices. Orange passed Shasta County in 1917, which previously for a number of years had exceeded all other counties in California, except Kern.

Deposits of undetermined value of iron and sand- stone have been discovered within the confines of this county. Quick- silver has also been produced. YUBA Land area: 639 square miles. Popidation: 10,375 (1920 census). Location: Lies west of Sierra and Nevada counties; south of Plumas. Yuba is eighth of the mineral producing counties of the state, and first in regard to gold output for 1925-1927, having passed Nevada and Amador counties in that metal. Iron and clay deposits have been reported in this county aside from the following commercial production shown for the year 1927. The increase over the 1926 figure of $2,921,083 was due mainly to gold obtained by the dredgers, which also yield silver and platinum. The 1921 dredge yield of gold was a record for the county. 150 MINERAL INDUSTRY OF CALIFORNIA The 1927 production of Yuba County was distributed as follows : Substance Amount Value Gold $3,468,201 Silver 11,893 fine oz. 6,743 Stone, miscellaneous 198,688 Other minerals 6,000 Total value $3,679,632 STATISTICS OF ANNUAL PRODUCTION 151 CHAPTER EIGHT TOTAL RECORDED MINERAL PRODUCTION BY COUNTIES Herein in the tabulations following we present the total mineral yield of each county of the state from the earliest available records to and including 1927. These tables were previously printed in ]\riNiNG In California, November, 1922, Chapter of Report XVIII of the State Mineralogist, which included the data to the end of 1921. In a number of cases it is known that there were productions of specific minerals in the years previous to the earliest years shown in these tabulations ; but unfortunately, there are few detailed or accurate records showing county segregations prior to 1894 when compilation of the statistical records of the California State Mining Bureau began. For gold and silver, the published reports of the U. S. Geological Survey and the Director of the Mint give county segregations back to 1880 ; but, prior to that year, we have only the state total annually. In the case of quicksilver, there are authentic records for all of the important ^ mines, from which we have compiled county tables for the early years. The "unapportioned" column is necessitated by the fact that in lany cases there is but a single operator or mine producing a given [mineral in the county. As it is the policy of the Division of Mines and Mining not to reveal the individual's private business without his con- [sent, we combine the values of such products. 152 MINERAL INDUSTRY OF CALIFORNIA IVLAMEDA Year Brick Chromite Pottery clay Coal 1 Manganese M Value Tons Value Tons Value Tons Value Tons Value 1890 1397 257 $534 344 1 1891 IRQ? 1893 IMd. 7,500 12,000 7.000 6.500 7,000 10,000 5,000 9,590 10,000 10.300 10.500 12,000 21345 28,770 1.800 14,800 20.919 19,660 12.800 13,977 22,668 14,841 23,551 and tile.. $37,500 60.000 35,000 35,750 35,000 60,000 40,000 67,130 60,000 82.400 90,000 95,500 413,750 474,350 10,800 140,000 195,889 153,330 133,100 122,937 159.205 132.765 315,941 290,033 258,812 369,778 664,918 365.853 > 828,048 763,476 938,375 808,779 587,402 468 600 318 504 440 290 130 423 870 $4,962 5,400 3.415 4,080 2,102 3,090 1,300 4,365 7,140 1$iQ5 IKQR 18P7 21,900 70,500 80,703 91,731 87,424 67,850 « 1 $50,370 176,250 242,109 332,066 262,272 203,550 1898 1899 iQon 1901 1909 1903 .- IQOd 60 900 1905 1906 1907 1908 1909 1910 1911 1019 10.000 12,610 16,370 45,348 9,541 10,500 $10,000 14,299 44,822 205,194 63,925 8,300 70 1 69 60 595 260 4,680' 1 552 500 i ; 20 36a 1 1913 itild 3.000 5,000 2,700 1,000 1 1915 1916 -- 1917 1918 319 562 1,211 2,746 1 > > 130 3,6^ 9,0( 30,2 109,8' 1,0 612 52 220 80 7,344 960 14,600 1.264 4,060 6,502 2,675 5,011 3,001 6.079 3 2,850 2,482 9,300 5,870 6,593 2,750 4,524 3,850 12,127 3,762 7,405 1919 1920 1Q91 1922 109^? 10 422 1,124 11,376 7,183 20,516 1Q94 1Q25 1Q9fi 1Q97 Totals ... $8,825,821 •1,817 $26,693 166,792 $435,279 '420,108 $1,266,617 9,351 $195,59!"

One feature that has added to the popularity of the publications is that many of them have been distributed without cost to the public, and even the more elaborate ones have been sold at a price which barely covers the cost of printing. Owing to the fact that funds for the advancing of the work of this department have often been limited, many of the reports and bulletins mentioned were printed in limited editions which are now entirely exhausted. Copies of such publications are available, however, in the office of the Division of Mines and Mining, in the Ferry Building, San Fran- cisco; New Orpheum Building, Los Angeles; State Office Building, Sacramento; Redding; Santa Maria; Santa Paula; Coalinga; Taft; Bakersfield. They may also be found in many public, private and technical libraries in California and other states, and foreign countries. A catalog of all publications from 1880 to 1917, giving a synopsis of their contents, is issued as Bulletin No. 77. Publications in stock may be obtained by addressing any of the above offices and enclosing the requisite amount in the case of publications that have a list price. Only coin, stamps or money orders should be sent, and it will be appreciated if remittance is made in this manner rather than by personal check. The prices noted include delivery charges to all parts of the United States. Money orders should be made payable to the Division of Mines and Mining. Note. — The Division of Mines and Mining frequently receives requests for some of the early Reports and Bulletins now out of print, and it will be appreciated if parties having such publications and wishing to dispose of them will advise this office.
