faction to all is impossible. I have therefore relied upon my own sense of fairness, and endeavored to present the truth impartially.

That errors may have been committed, and false statements given by interested parties, is probable, but precaution has been taken to guard against them. The selection of assistants was made with reference to their integrity and capacity. Instructions were given to them in detail, enjoining careful scrutiny and verification of every statement. The revision of their work, under these precautions, has occupied more than four months. There is no subject upon which greater difference of opinion exists than that of mining statistics. It is an open field in which there is room for discrepancy under any existing circumstances. No two persons rate the product of the precious metals alike. The superintendent of a mine often furnishes information which when submitted to the board of directors is pronounced incorrect. Representatives from the mining districts are apt to rate both population and products higher than persons who have made them special subjects of inquiry, but whose opportunities for judging may not be so favorable.

A fruitful source of error is in supposing that the ordinary channels of transportation cannot be relied upon as a clue to the gross product of the mines. It is alleged that large quantities of the precious metals are carried away in the pockets of the miners. Even if this were so, it is not reasonable to suppose that the miners continue to burden themselves with their treasure after arriving at their place of destination. It must find its way into the mint or branch mints for coinage or the custom-house manifests for exportation. It cannot be assayed without paying its internal revenue tax. The gross yield of all the mines can be determined with approximate accuracy. It is more difficult to arrive at a subdivision, when it comes to the product of each State and Territory. In California, for example, during the early days of placer mining, before the transportation of bullion by organized companies had become a business entitled to confidence, a large proportion of the gold derived from the mines was carried out of the country by private hands. There was comparatively little danger of loss. The routes to San Francisco were short, public, and protected by general interest. From that point to New York the passengers usually combined for mutual protection, and the risk was inconsiderable. It was not until the idle and the profligate began to obtain an ascendency, the business of transportation by express more firmly established, and the mines more difficult to work with profit, that tlic increase of risks and reduction of charges resulted in the general abandonment of this system. It doubtless prevails to a limited extent now, but the transportation of bullion by private hands in California is exceptional. It probably does not exceed seven per cent. in the aggregate, and this applies only to the routes by which it reaches San Francisco. In reference to silver it is impossible that any considerable amount cani escape notice in this way. The yield of Nevada can be determined with more accuracy than that of other States. Silver predominates in the mines; and where gold is obtained it is not in an uncombined form. When we come to Montana, Idaho, Washington, and Oregon the greatest difficulty is experienced.

Shipments of treasure from Montana and Idaho may become incorporated with others before reaching their destination. From Montana most of the bullion goes east. Two main routes are open to examination-one by the Missouri river, the other by Salt Lake City. Indian disturbances and the insecurity of the roads have during the past year almost entirely closed the latter; so that the chief exit is by the former route. Shipments from Idaho are made chiefly by way of Portland and the inland stage route through Humboldt and across the Sierra Nevada. On both of these routes it is alleged that they are liable to become merged with the products of other States and Territories. It has been impossible to obtain an account of the shipments from each agency at the express office of Wells, Fargo & Co., at San Francisco. For reasons of private expe

diency they refrain from giving the desired information. We have, however, the aggregate receipts at their office, and knowing very nearly what amount can fairly be credited to California, Nevada, and British Columbia, can draw reasonable conclusions as to the proportion derived from Idaho, Washington, and Oregon. From the best information available the following is a near approximation to the total gold and silver product for the year ending January 1, 1867:

$25,000,000 20,000,000 12,000,000

6,500,000 Washington

The bullion product of Washington is estimated by the surveyor general at $1,500,000. That of Oregon is rated as high as $2,500,000. Intelligent residents of Idaho and Montana represent that the figures given in the above estimate, so far as these Territories are concerned, are entirely too low, and might be doubled without exceeding the truth. The product of Idaho alone for this year

is said to be from $15,000,000 to $18,000,000. That of Montana is estimated by the surveyor general at $20,000,000. Similar exceptions are taken to the estimates of Colorado, New Mexico, and Arizona. As I have no grounds for accepting these statements beyond the assertion that most of the bullion is carried away in the pockets of the miners, I am inclined to rely upon the returns of the assessors, express companies, and official tables of export. Admitting that a fraction over seven per cent. may have escaped notice, although reasonable allowance is made for this in the estimate of $70,000,000, and that a considerable sum may be derived from sources not enumerated, I feel confident the additional allowance of $5,000,000 is sufficient to cover the entire bullion product of the United States for the year 1867, thus making the aggregate from all sources $75,000,000, as stated in the report of the Secretary of the Treasury.

I have endeavored to obtain returns of the annual product of each State and Territory since 1848; but, for the reasons already stated, and in the absence of reliable statistics, it has been impossible to make the necessary divisions with more than approximate accuracy. As nearly as I can judge from the imperfect returns available, the following, in round numbers, is not far from the total product:

$900,000,000

90,000,000 65,000,000

This statement requires explanation. Up to 1855 a considerable portion of the gold taken from California was not manifested. In 1849 the actual yield was probably $10,000,000; in 1850, $35,000,000; in 1851, $46,000,000; in 1852, $50,000,000; in 1853, $60,000,000; and in 1854, $53,000,000. The amount unaccounted for by manifest was not so great after the last date. In 1861 Nevada and Idaho commenced adding their treasure to the shipments, so that after that date a deduction for the amounts produced from these sources would be necessary, if the manifest alone were taken as a criterion, in order to arrive at the product of California.

An addition should be made for the amount retained for currency, estimated by some as high as $45,000,000, but probably not exceeding $35,000,000 or $40,000,000; and for plate, jewelry, &c., of California gold, say $2,000,000, and Nevada silver, $3,000,000.

Incorporated in these shipments are the amounts received from Nevada, Idaho, Oregon, Arizona, Washington, and British Columbia; but these cannot be deducted from the manifest of exports, according to the express returns, since the proportions are not accurately known of the amounts, retained and shipped, derived from separate sources.

The general condition of the mining interest on the Pacific slope is encouraging. There have been fewer individual losses than during past years, and the yield of the mines has been comparatively steady and reliable.

Fluctuations in mining stock have not been so great as usual, and those wild and injurious speculations which have impaired confidence in this great interest are gradually becoming narrowed down to individual operators, whose influence in the community is limited.

Legitimate mining has been as prosperous as other pursuits, though it cannot be denied that there are uncertainties attached to this peculiar business which render it hazardous and require more than ordinary profits to make it remunerative under the most favorable circumstances. It may seem strange in this view that the gross product of bullion has been gradually diminishing for some years past, but a brief referenco to the history of mining operations on the Pacific coast will explain this apparent anomaly.

The existence of gold in California was known long before the acquisition of that territory by the United States. Placers had long been worked on a limited scale by the Indians; but the priests who had established the missionary settlements, knowing that a dissemination of the discoveries thus made would frustrate their plans for the conversion of the aboriginal races, discouraged by all means in their power the prosecution of this pursuit, and in some instances suppressed it by force. As early as December, 1843, however, Manuel Castanares, a Mexican officer, made strenuous efforts to arouse the attention of the Mexican government to the importance of this great interest.

It is not my purpose to enter into a detail of the events preceding the discovery by Marshall on the 19th of January, 1848, or the subsequent excitement which resulted in the opening of the great placer mines, and the rush of immigration in 1849. Reference is made to these incidents in the history of California merely to show the changes in the character of the business. At first gold was easily found, and required but little skill in separating it from the loose gravel or sand in which it was imbedded. Frequently it lay so near the surface in such quantities and in grains of such form and size, that a simple pan or rocker comprised all the means necessary, with ordinary labor, to insure extraordinary profits. Mere will and muscle were sufficient. Our people were inexperienced, but ingenious in devices for saving labor, energetic and industrious.

Unskilled as they were, nearly all who went into the business realized handsomne profits; and the reports of their success induced a rapid immigration from the Atlantic States, South America, Australia, and other parts of the world.

Thus towns were built up; a new and extensive commerce sprang into existence;

lands were cultivated to supply the ininers; roads were cut through the difficult passes of the mountains; steamboat and stage lines were established; and the country from the western slopes of the Sierra Nevadas to the shores of the Pacific, for many hundred miles north and south, became suddenly filled with an industrious, intelligent and enterprising population. Even in those early days, however, as the surface placers receded towards their sources, time and money were expended in the rediscovery of inventions which had been known to the old world for centuries.

With all the genius and enterprise of the American people, no important discovery in the way of machinery for mining was made which had not been long in use in South America, Mexico, or Europe. The same necessities gave rise to identical contrivances for saving labor, and it is sufficiently creditable to our miners to say that without any knowledge of what others had done, they frequently improved upon the originals. The fact demonstrates very clearly that want of knowledge, even in the preliminary stages of mining, is a source of loss. When the precious metals are easily obtained, and the profits of individual labor are large, less injury results from ignorance than in the subsequent stages of the business, when capital is required and the process of reduction is more complicated. Mining differs essentially from every other branch of industry. Unlike agriculture, there is but one crop in a mine. As the work progresses the stock of mineral is decreased, and can never be replenished by any human art. There is no opportunity of recovering what has been lost or wasted.

The farmer changes his crop or his system of cultivation; and his land can be improved and his profits increased by experience. So also in manufactures and other pursuits. Hence it is important that the experience of mankind should be preserved so that crror may be avoided.

Comparatively little progress was made in vein or quartz mining prior to 1860. Quartz veins containing the precious metals were discovered in California in 1850, and for several years experiments were made in working them, generally with loss. The Mexicans with their arastras were the only successful quartz miners. Experience in their own country enabled them to realize fair profits upon their labors. Their system of mining, however, was too slow for an American population, to whom large investments of capital were of no consequence, provided there was a prospect of immediate and abundant returns.

The discovery and development of the Comstock lode in Nevada gave the first impulse to this kind of mining. The wonderful richness of that vein attracted attention at once, and drew from all parts of the world men of scientific attainments. By the developments made in working it, the principle was established that quartz veins could be rendered a profitable source of supply on the Pacific

The experience thus gained impelled the adventurous miners of California to attempt new systems, and devote themselves with greater vigor to the opening and working of the gold-bearing veins in that State.

In 1860 the product from this source in California did not exceed $2,000,000. As the surface diggings gave out, a resort to vein mining became indispensable.

The proportion of bullion now derived from various sources within the limits of the State is about as follows: from surface diggings, $2,000,000; from cement or deep-lying placers, $18,000,000; from quartz mines, $9,000,000-total, $25,000,000.

Professor Ashburner estimates that about 80 per cent of the gold is produced from the mines lying north of the Mokelumne. The production of the southern mines is diminishing every year, and the surface diggings will soon be exhausted. Wherever the latter predominated a sudden but ephemeral prosperity was engendered. General stagnation now prevails; towns are depopulated; real estate is of little value; business is depressed. The population consists of hundreds in many counties where it formerly consisted of thousands. Reference to the accompanying reports will show the present condition of these

coast.

localities. Good quartz veins exist in many of them, but the want of capital has retarded their development. Unskilled labor can make no further progress, and new fields of enterprise have been sought by those who formerly depended upon the placers. Some have pushed their way over the mountains into Idaho, Montana, and other new Territories; others have given up mining and devoted themselves to farming, trade, or commerce.

Similar changes have been experienced in Idaho, Montana, and other Territories in which surface mining attracted a population. At first the yield was large and easily obtained; as the surface deposits were worked up to their sources quartz veins were discovered, and machinery and skill became requisite; the difficulty of access to the more remote mineral regions increased the expense of transportation, and the uncertainty of remunerative results impaired confidence. History shows that these changes occur in all mining countries and are inseparable from this branch of industry.

No uneasiness need be felt as to a decrease in the source of supply. After many years of travel over the mining regions, I feel justified in asserting that our mineral resources are practically without limit. Explorations made by competent parties during the past year in many parts of the mineral region hitherto unknown demonstrate the fact that the area of the mineral deposit is much larger than was ever before supposed. It is safe to assume that of the claims already recorded in the settled parts of the country, and known to be valuable, not more than one in a hundred is being worked; and of those worked perhaps not more than one in fifty pays anything over expenses, owing to mismanagement, inefficient systems of reducing the ores, want of capital, cost of transportation, and other causes susceptible of remedy. In many districts of Nevada silver ores of less value than $100 a ton cannot be worked by mill process so as to pay expenses; and there are districts in Idaho and Montana where gold-bearing ores will not justify working unless they yield from $40 to $50 per ton.

With such wealth of treasure lying dormant, it cannot be doubted that, by the increased facilities for transportation and access to the mines soon to be furnished by the Pacific railroad and its proposed branches, and the experience in the treatment of ores, and the scientific knowledge to be acquired in a national school of mines adequate to the necessities of the mining population, the yield must eventually increase.

The adventurous Americans who take the lead in the development of these frontier regions are generally energetic and intelligent, but prone to extravagance and reckless speculations. No country in the world can show such wasteful systems of mining as prevail

At a moderate calculation, there has been an unnecessary loss of precious metals since the discovery of our mines of more than $300,000,000, scarcely a fraction of which can ever be recovered. This is a serious consideration. The question arises whether it is not the duty of government to prevent, as far as may be consistent with individual rights, this waste of a common heritage, in which not only ourselves but our posterity are interested.

The miner has a right to the product of his labor, but has he a right to deprive others of the benefits to be derived from the treasures of the earth, placed there for the common good? The precious metals are of an imperishable nature, evidently designed to pass beyond the reach of the discoverer and to subserve purposes of human convenience for generations. Our children have an interest in them which we cannot with propriety disregard.

The bill to establish a national school of mines, introduced in the Senate, at the beginning of the present session of Congress, by Mr. Stewart of Nevada, is designed to remedy this evil. Similar schools have been established in various parts of Europe, and the best evidence of their utility is the fact that we are indebted to them for nearly all the knowledge we possess on the subject of mining and metallurgy. Our mines and mills are practically managed by foreign

in ours.
