The California Commission for the Paris Exposition of 1878 had its origin in a pubHc meeting of citizens, which issued an address to the people of California, setting forth the advantages to the State that would result from an exhibit of the various agricultural, mechanical, mineral and art productions of the Pacific Coast. Committees in the different departments were appointed, who assumed their duties cheerfully. Much pro- gress was made by these committees. The Commission was warmly supported by the Press, and was popular throughout the State. It was supposed that all its varied resources would be shown in such a manner as to place California in the posi- tion it deserves before the world. As the work progressed, it was found that a considerable sum of money would be required to carry out the plans of the various committees, and it was decided to make an application to the Legislature of the State, then in session, for the necessary funds. Much time was lost while awaiting the action of that body. The Legislature declining to make the appropriation asked, it was found to be too late to provide other means for completing the work. Considerable progress having been made in the Mineral Department, and funds being generously placed at its disposal by a public spirited citizen, it was decided to make the collec- tion as complete as possible, and to send it forward. IV It is due to the other committees to say that had they been able to carry out their plans, their exhibits would have been of equal, if not of greater interest to the world, for it is not gener- ally known how immense our resources — other than mineral — really are, while California as a great mineral producing State is known far and wide. In making an exhibit of minerals and mineral products, it was thought best to include the whole Pacific Coast, as Califor- nia capital is largely invested in the mines of the other states, and most of the offices of mining companies are at San Francisco. PACIFIC STATES. The Pacific States are generally understood to be those which look to the Pacific sea coast cities for their supplies, and which are dependent for capital on those cities. They may be enum- erated as follows : California, Oregon, Washington, Utah, Ne- vada, Arizona, Idaho and Alaska. Montana, Wyoming, Colo- rado and New Mexico hold a middle position, but look more to the East for their supplies, and send their products in that direction more than to the Western sea board. Some of the Pacific States are noted for their fertile agricul- tural lands, and others for their mineral wealth. All are capable of supporting a large population, and the climate is such that manufactures can be carried on to great advantage. California has a sea coast of 700 miles in length, embracing 9 degrees of latitude ; the mean width of the State is about 200 miles. It has an area of nearly 16,000 square miles; greater than New England, New York and Pennsylvania combined ; two chains of mountains, parallel to the general trend of the sea coast, extend its entire length. The Sierra Nevada chain is the great back-bone, so to speak. The rain falling on these mountains divides at the summit, one portion finding its way to the Pacific ocean, the other flowing into the great basin, where it either sinks into the loose, sandy soil, or spreads out into lakes of greater or less magnitude, which are kept in a state of equilibrium by evaporation. The Coast Range is a low chain of mountains running near the sea coast, as the name indicates^ In^the Southern part of the State a third chain of mountains lies East of the Sierra Nevada, separated from it by a narrow valley ; — they are called the Inyo mountains. They differ from other mountains of California, in being highly argentiferous Owens Valley, which separates them from the Sierra Nevada, is remarkable for its nearly equal width, and great length, extend- ing as it does for loo miles in a direction somewhat West of North. The mountains both East and West of Owens Valley are the highest in the State, and some of the peaks the highest in North America. Mount Whitney reaches an altitude of 15,000 feet. This celebrated mountain is surrounded by at least 100 peaks, all of which are over 13,000 feet in height. San Francisco possessing, the great sea port of the Western Coast, and being the terminus of the various railroad lines, can and does furnish the mines with their principal supplies, while San Francisco mechanics employ a large number of workmen in the manufacture of mining machinery, in which branch of workmanship they cannot be excelled. On the other hand, most of the product of the mines finds its way to San Francisco, from whence it is sent to all parts of the world. The fact that San Francisco Bay is the only perfect sea port from Acapulco to the Straits of Fuca, gives to California a great commercial advantrge over her sister States. Add to this her equable climate, her boundless natural resources, and the future greatness of the State cannot be questioned. California owes her present greatness to the accidental dis- covery of gold in 1848. The presence of gold in California had been suspected, if not actually known, for many years. It is well known that gold bearing quartz was worked by a French- man named Baric, at a locality near the Mission of San Fer- nando as early as 1843. Placer gold in moderate quantities had been found at a still earlier period, but the discovery of rich placers at Sutter's Mill by Marshall, in 1848, may be re- garded as the New Era. VI This discovery caused a flood of population to the State from every part of the world. No doubt the vast agricultural resources of California would have eventually attracted a large population even had gold been unknown, but a longer time would have been required to effect it. The following figures, furnished by the Journal of Com?nerce of San Francisco, will convey some idea of the agricultural pro- ducts of the State : Wheat crop from 1855 to 1877, inclusive, 22 years, 195,595,000 centals. Barley crop from 1862 to 1876, inclusive, 15 years, 57»350'Ooo centals. Of Corn, (Maize), from 1870 to 1877, inclusive, 8 years, the product was 5,990,000 centals. The Wheat crop of 1877 was 12,895.000 centals, val- ued at $26,000,000. The yield of the Vintage of 1877 was 8,000,000 gallons of wine. The yield of Wool in CaHfornia from 1854 to 1876, inclusive, 23 years, was 384,061,145 pounds. Total product of the entire Pacific Coast for the same period ,452,011,145 pounds, valued at $86,- 500,000. The yield for the year 1877 was 53,- 110,742 pounds, valued at $9,500,000. The commercial importance of California may be seen by the following statistics from the same source. Total population of the Pacific Coast, 1,650,000. Population of California, 938,000. Population of San Francisco, 308,215. Custom dues collected in 1877, $6,692,432 56. Total imports, 1877, $75,713,272. Total exports, 1877, $61,911,237.' Immigrants arrived, 1877, 62,171. Emigrants departed, 1877, 45,257. VI 1 Value of the product of whale fisheries, 1877, $319,568. Number of vessels engaged, 12. Tonnage, 3,452. Value of manufactured products of the State in 1877, $61,000,000. The gold bearing belt of California known as the great mother vein, commences in Kern county, and extends through the following counties : Tulare, Fresno^ Mariposa, Tuolumne, Calaveras, Amador, El Dorado, Placer, Nevada, Sierra, Plumas and Shasta. All the noted mines of California lie along this belt. The lithological character of the formation is peculiar, and is easily recognized by mining men and prospectors. It is so metamor- phic in its character that its geological age is not with certainty known. No fossils have been found, except on the Mariposa Estate, in Mariposa County. For a description of these, which are undoubtedly Jurassic, reference may be made to the Geo- logical Survey of California, Geology, Vol. i. Folio 226. The circumstances under which these fossils were found, the few specimens obtained, and the metamorphic character of the formation in which they occur, scarcely warrant the assumption that the entire belt is of Jurassic age. The gold bearing rocks of California afford an interesting field for future geological investigation. MINING. Mining, as practiced in California, may be divided into three distinct classes. Placer Mining. Hydraulic Mining. Working of Mineral Veins. When gold was first discovered, it was sought only in the beds of rivers, on the bars and shoals formed by the currents and eddies of. swift running mountain streams. The first appli- Vlll ances were rude and imperfect. Still gold was so abundant, that large quantities were collected by simply washing pansfuU of the rich earth, and by what was called "crevicing," which is seeking depressions in the bed rock and taking from them, by the simple process of removal, the accumulation of years with a knife or other instrument, and washing it in an iron pan, at the rnargin of some convenient stream. Gradually the bars were worked out and the gold was sought in the alluvial deposits, on the borders of the rivers, sometimes with success, but often otherwise. As these deposits contained less gold than those first dis- covered in the beds of streams, labor-saving machinery was required, that larger quautities might be subjected to the wash- ing process. This want led to the introduction of the cradle, long tom, and the sluice with its improvements, such as the block-riffles, zigzags, undercurrents, &c. When these deposits failed or were found less profitable, hydraulic mining naturally followed, as an improvement on all other methods of collecting Placer gold. Only under the following conditions is hydraulic mining practicable. I St. The alluvial auriferous earth, no matter what its depth may be, must be moved to the bed rock. 2d. A channel must be made with sufficient fall, by which an unlimited quantity of the refuse or tailings may be carried away. 3d. A sufficient supply of water to keep the tailings in mo- tion in the sluice, and to carry away all the earth after it is disintegrated by the stream from the hydraulic nozzle. 4th. A constant stream of water from a reservoir, sufficiently high to give the requisite force to wash away the bank and disintegrate the deposit. This system of mining, is not only very profitable, but pro- duces large quantities of gold annually from deposits which would otherwise be worthless. IX The following statement, from published statistics on this subject, will show the great advantage of this system over others : Cost of moving a cubic yard of gravel, miners' wages being $4 per day : With the Pan $20 00 " Rocker 5 00 " Long Tom i 00 " Hydraulic System ... o 05 Some of the Hydraulic mines are worked in California on an immense scale, very large sums of money being invested for years before any return is possible. Vein mining is conducted in California and other Pacific States, much as it is elsewhere. The country being new, and labor high, advantage is taken of every form of labor-saving machinery. According to the best authorities, the Pacific Coast is not behind other parts of the world in carrying out its gigantic mining operations. YIELD OF THE PRECIOUS METALS. The following, from statistics furnished by the San Fran- cisco Journal of Commerce, shows the total yield of gold and silver during the last 29 years: Gold : . 1,561,409,508 Silver 407,426,678 Total 1,968,836,186 Wells, Fargo & Co. have published a statement of the yield of precious metals for the year 1877, which is given in full.

WELLS, FARGO & COMPANY, Exchange, Banking and Express. Office Gen. Superintendent, San Francisco, Dec. 31, 1877. Dear Sir : The following is a corrected copy of our annual statement of precious metals produced in the States and Terri- tories west of the Missouri River, including British Columbia, and receipts in San Francisco from the West Coast of Mexico, during 1877, which shows an aggregate result of $98,421,754, being an excess of $7,546,581 over 1876, the greatest previous annual yield in the history of the country. Arizona, Colorado, Idaho, Nevada, New Mexico, Oregon, Utah and Washington increase ; British Columbia, California and Montana decrease ; but it is possible the falling off in Montana is more apparent than real. In our statement for 1876, Dakota (Black Hills) was not mentioned. That territory is included herein, credited with $1,500,000 gold, but the estimate is uncertain, as $950,000 is the total amount carried out of it during the year by all ex- press companies and mails. The amount named as carried by other conveyances from Dakota is conjecture. If the Com- stock mines yield as much in 1878 as during the present year, the aggregate product oi silver and gold from all sources named, will approximate one hundred millions of dollars.

The gross yield for 1877, shown above, segregated, is, in round numbers, as follows : Lead, 5% $ 5.085,250 Silver, 48% 47,206,957 Gold, 47% 46,129,547 $98,421,754 As lead is an important element in what is herein termed base bullion, we might add that of Missouri and Illinois, value approximately $1,500,000; which, with the silver and gold of the Lake Superior country, Virginia and North and South Carolina, amount say $500,000, would swell the gross product to over $100,000,000 for the year. The lead product of Utah, Nevada and California, exceeds that of the remainder of the Xll United States and Territories combined ; and in tonnage, is greater this year than ever before, though not exceeding in value that of 1876, the average price having been lower than for many years past.

The greatest amount in former years was $83,650,000, in 1857. The amounts exported during the present year, were approximately as follows: From Southampton, $80,000,000; from San Francisco, $19,000,000 ; from Marseilles, $4,000,000 ; from Venice, $2,000,000. We take plasure in acknowledging the prompt responses of persons applied to for information, and to whose cordial co- operation we are indebted for much of the data necessary to our compilations. J no. J. Valentine, General Superintendent. Gold and silver are not the only mineral products of the Pacific Coast. The Quicksilver interests are of very great im- Xlll portance, Mercury being an essential in the extraction of gold and silver, for which purpose it is largely used in the State. Besides which, great quantities are exported. There are a number of Quicksilver mines in the State which are paying handsome dividends on the capital invested. The principal mines of Quicksilver, are enumerated in the following table, which also shows the production of each for the year 187^, in flasks : ' New Almaden 24,079 Redington 9,400 Sulphur Banks • 1 1,303 Guadalupe * 6,241 New Idra 6,560 Great Western 5,875 Altoona 1,417 St. John's 2,000 Oceanic • 2,628, California 1,490 Oakland i,395 Cloverdale 1,300 Sunderland 1,200 Abbott 836 Manhattan 457 Napa Consolidated 2,366 Buckeye 466 Phoenix 250 Gt.

These mines were first worked for (quicksilver in 1845, but the operations were on a small scale, and no record exists earlier than 1850. They have been, and are now, the most productive quicksilver mines in the world, excepting only the mine of Al- maden in Spain. They are developed to a depth of 1,300 feet, and the workings extend horizontally, somewhat in the shape of the letter Y. Between five and six hundred men find steady employment — the work being actively prosecuted throughout the year. From the first of January, 1864, to the thirty-first of December, 1875, the number of feet of drifting and sinking on the mines of the Company, as shown by the records, amounted to 129,724 feet, or 26.24 niiles, at ^ cost of $1,000,000. This does not in- clude the excavations made in extracting ore during the period named, nor any expenses for the same. In 1875 there were used in the mines 2,361 kegs of black powder (25 lbs. each), and 9,350 lbs. of Ciiant and Hercules powder — the rock in most cases requiring to be drilled and blasted. At the close of the same year, about five miles of railroad, underground, were in operation, and over 2,000 drills were in active use. The reduction works consist of nine furnaces, and include the most improved methods for working quicksilver ores. When the present improvements are finished, they may be considered as most complete and perfect in every respect. \ BASE BULLION. The product of lead and base bullion is an important inter- est. By base bullion is understood crude lead, in which the silver and gold contained in the ores from which it is smelted still remains. It must be refined before it becomes an article XVI of general commerce. Part of this xork is done at extensive metallurgical works in San Francisco, Sacramento and Contra Costa, while large quantities are sent abroad for treatment. The following is a statement for the year 1877 : Receipts for the year have been as follows : Base Bullion, lbs. Lead, lbs.

True coal is unknown on the Pacific Coast, but lignites and brown coal are abundant. Some of the brown coals are of good quality, and answer many purposes, such as making steam, household use, etc. The want of first class coal has been a se- XVll rious drawback when extensive manufacturing enterprises have been proposed. A large quantity of coal is imported into the State annually. I'he discovery of carboniferous rocks in Cali- fornia, Nevada and Arizona, leads to the hope that beds of true coal may eventually be found.

The discovery of Boracic Acid, and the natural borates on the Pacific Coast, was made in January, 1856, by Dr. John A. Veatch, who was engaged in making an analysis of water, from Lick Springs, in Tehama County, California. Having occasion to evaporate a large quantity of the water, he was surprised to XVlll find borax crystallizing out. This discovery led to tlie examina- tion of all the mineral waters then known, which resulted in finding Boracic Acid in nearly all of them. In September of the same year, Dr. Veatch discovered Borax Lake. This lake is situated in Lake County, California, one hundred and ten miles from San Francisco. Borax Crys- tals in large quantities have been found in the stratum of soft mud, forming the bottom of the lake. Besides the crystals, borax exists in solution in the water itself, from which it can be obtained by evaporation. Borax Lake produced with profit, from its discovery until the still more remarkable discovery of the immense deposits in Nevada and in Southeastern California, considerable quantities of refined Borax. In the year 1865, the yield was 240 tons; in 1866, the daily average yield was 2^ tons. Boracic Acid, free or combined, is of common occurrence on the Pacific Coast ; it has been found in the waters of the Pacific Ocean, along the shores of California and Oregon. Common salt, made by evaporating the sea water, contains more than traces of Boracic Acid. It has been found in the waters of Mono and Owens' Lakes. In all probability, if an examination of the bottom of these lakes should be made, crystals or borax would be found in the mud, as at Borax Lake. Very extensive deposits of Borax have been found near these lakes ; one company — which is incorporated — is in pos- session of a large portion of what is known as Columbus Marsh. This remarkable saline deposit, lies in the State of Nevada, in latitude 38° 5' North, and longitude 118' West. As laid down on the State Geological Map, it is an irregular oval in form, ten miles long, by seven miles wide. It is distant from Mono Lake 46 miles, in a direction a little north of east. It has evidently been an Alkaline Lake, much as Mono Lake is now. If Mono Lake did not continually receive the melting snows from the Sierra Nevada, its bed would soon, like Columbus Marsh, be- come a dazzling field of Alkaline salts. This, and similar deposits, consist of common Salt, Sul- phate of Soda, Borate of Lime and Borax. XIX The Borate of Lime — Ulexite — is found in rounded concre- tions, from the size of peas up to three or four inches in diam- eter. Large quantities of Borate of Lime were shipped to San Francisco, but it was found that the expense of transportation was greater than the highest price that could be obtained in that or the European market. It was soon discovered that the AlkaHne deposit, in which the Ulexite occured, would yield Borax if dissolved and crystallized. The method now adopted is, to rake the deposit into heaps like hay cocks in a meadow. These are hauled to the dissolving pans, under which large fires are kept burning. The impure solutions are run into vats from which a good article of crude Borax crystallizes on cooling. Extensive fields of Alkali, containing Borax in varying quan- tities, are known to exist from Wadsworth, quite to the State line southward. These deposits have furnished the product shown in the following table, taken from the San Francisco Commercial Herald and Market Review of jh*ft€ 17, 1878. ^^^^^/h^^ Receipts of Borax at San Francisco : 1876. 1877.

Copper may be classed among the mineral products of the Pacific Coast. In a country where the precious metals are found, the mining community often overlooks the useful and less valuable metals. This has been the case on the Pacific Coast. Considerable copper has been shipped from San Francisco to Swansea and other European markets, but the quantity has been small as compared with the extent of the mines known to exist. The most important copper producing locality in California, is Calaveras County; the mines at Copperopolis were for a time XXI extensively worked. The yield of the Union mine, according to the report of J. Ross Browne, from the time it was opened in 1861, to July 15, 1877, was 108,731,678 pounds; all of which was exported to the Atlantic States and Europe. The receipts from sales of ores produced by the Keystone mine, were $375»ooo- There are copper mines of undoubted value in Amador, Mariposa, San Luis Obispo, Los Angeles, Plumas, Del Norte, Contra Costa, Nevada and Inyo counties. In Oregon, copper occurs in considerable quantities. In Douglas county, masses of the oxides and carbonates of copper of great importance are known to exist. Lower California too is known to possess extensive and valuable copper mines, which is also the case with Nevada and Arizona. Attention has lately been called to the importance of cop- per mines producing large quantities of low grade ores. The San Francisco copper mine at Spenceville, Nevada County, CaHfornia, is an example. This mine is said to be very exten- sive, the ore is cupriferous pyrites, very free from gangue ; the average copper in the ore is 6.40 per cent, although ores may be obtained by selection, yielding as high as 1 7 per cent. The mine is being worked «xci«sively, and according to the state- ment of the owners, with profit. The sulphur present in the ores supplies fuel in roasting, which is done on a large scale in heaps. The resulting product is leached with water, and the soluble copper precipitated by metallic iron. The excess of sulphur is now wasted, but eventually it is intended to erect acid chambers and otherwise to utilize the by-products. TIN. Tin occurs in the Temescal Mountains, in San Bernardino county, California. For some reason work has been suspended for years since its discovery, so that it is impossible to say whether this metal will become a valuable product of the State or not. The ores, which have reached San Francisco from time to time, have been sufficiently promising to warrant the xxn opinion that the question of value is one of quantity rather than quality. CHROMIC IRON. Chromic iron is found in many localities in the State of California; large shipments have been made to the Eastern States within the last eight or ten years The supply may be considered practically inexhaustible. PETROLEUM, ASPHALTUM, ETC. Superficial evidences of the existence of Petroleum and other hydro-carbons have long been observed in different parts of California. Extensive deposits of Asphaltum are found in the Southern counties of the State. It is only lately, however, that any important practical results have been obtained from the numerous experiments made in refining the crude products. Much disappointment has resulted from the discovery that the Pacific Coast Petroleum yields but a small quantity of light oil suitable for burning. But large quantities of heavy oil, admi- rably fitted for lubrication and other purposes, is being manu- factured in the State, and the production is steadily on the increase ; a certain portion of light burning oil is obtained, and it is hoped that this product will be greater when more exten- sive explorations are made. The imports of California Petro- leum into San Francisco, from January ist, 1878, to April ist, 1878, was 72,000 gallons. Asphaltum is largely used on the Pacific Coast, for roofing, pavements and in the manufacture of sewer and water pipes. LIME, GYPSUM AND CEMENT. Lime, Plaster of Paris, and Cement, are largely produced and manufactured in California ; Gypsum occurs in many localities in quantity. The manufacture of calcined plaster has recently been added to the list of Pacific Coast industries. The Golden Gate Plaster Mills produce an article which is generally preferred to that imported. The following table gives the receipts of California Lime for the years 1876-77 : XXUl Months. J^?*'- J877. DDlS. DblS.

The cost of coal, labor, and other expenses are so great, that capital will scarcely embark in iron manufacture while so many better paying invest- ments are to be found. It is interesting however, to know that the supply is unlimited and may be made available when the wants of the country demand its production. Oregon has found it to her advantage to commence working her iron deposits and the result is said to be satisfactory. DIAMONDS. Diamonds have been found in California ; they are gener- ally microscopic. A few of moderate size are known. They are generally found associated with Zircons, Topaz Magnetite, Platinum, Iridium, Chromite and Ilmenite. Microscopic Diamonds have been found on the sea beach on the Coast of Oregon and California, in washing the sands for the gold they contain. They are sometimes also found with gold, in the sjuices of Hydraulic mines. The claim of the Spring Valley Hydraulic Mining Company is a well known locality. The largest stone on record, was XXIV found at Forest Hill, El Dorado County; it Aveighed S-j(yo% grains. It was of good color, but was defective. Another notable stone was found at Fiddletown, Amador County ; its weight was 3.tVo% grains. Four other Diamonds are known to have been f jund at this locality. Another Diamond of rather large size was found at Cherokee Flat, Butte County. It was of a light straw color; when set in a ring in its natural state, it was a brilliant and beautiful stone. At least forty other Diamonds, mostly of small size, have been found at this locality. MISCELLANEOUS MINERAL PRODUCTS. There are other mineral products of the Pacific Coast which have great economical value, and which have been worked more or less extensivelyT Among the more important of these may be mentioned the following : Asbestus, Antimony, Alum, Alkali, Bismuth, Building Stones ; including many varieties of Marble, Baryta, Clays, Cobalt, Diatomaceous Earth, Graphite, Iridium, Mica, Manganese, Natural Paints, Nickel, Nitrate of Soda, Platinum, Pyrites, Steatite, Sulphur and Slate. NEW DISCOVERIES. The Pacific States not only produce large quantities of the precious and useful metals, but are likely to continue to do so. The future magnitude of the mining interest can scarcely be overestimated. There seems more fear of an over production of the precious metals than any decrease in the yield. New discoveries are continually being made, and the area of known mineral territory is widely extending. What California and Nevada have done in the production of gold and silver is likely to be repeated in Arizona and Mexico, which are now attracting the attention of prospectors and capitalists. The ores brought from these new fields are wonderfully rich, and it only remains to prove the deposits extensive. If this should be the case, there will be a flood of silver poured into the treasuries of the world, which may upset values, as the discovery of gold in Cal- ifornia and Australia did a qqarter of a century ago.

No geological exam- ination of the locality has been made, but it seems to be an ancient lake or shallow sea, into which streams bearing much sedimentary matter have discharged. It is not easy to ac- count for the silver. Specimens will be furnished to those who wish to study them. In this connection see No. 528.
