THE discovery of petroleum in Pennsylvania in 1859 marked the birth of an industry of paramount importance. Spreading from - Oil Creek, this remarkable industry may be said to have embraced the earth in a little more than half a century. Those who made the discovery little realized its deep significance or far reaching influence on our national life. For over sixty years, during which time this nation has created and developed the oil industry to a high state of efficiency and' carried its activities to all parts of the world, we have' at all times been the leaders in the production of crude oil and in the development of its technology. During the unprecedented growth and expanse of the oil industry there has been an increasing dependency of our basic industries on, petroleum, until at present it has become essential to our national existence. To meet the ever increasing demand for petroleum and its products, we have explored, at one time or another, for their oil possibilities, practically all parts of the sedimentary rock area in the United States. Furthermore, detailed surface and, in many places, subsurface studies have been made of all the promising regions; over 640,000 jewells have 'been drilled for. oil since the beginning of the industry; $12,000,000,000 have been spent in this work; seventeen major fields exceeding 100,000 bbl. daily production and more than a thousand minor pools have been opened up, and 8,000,000,000 bbl. 'of oil have been produced, or an amount nearly equal to the estimated future reserves of the United States made in 1921.

AMONG the members of the Institute there are thirty-three who have been members for a half- century or-more Some time ago a professor of psychology made a careful study of a group of unusually brilliant children to determine whether there was any truth in the general belief that a brilliant mind is usually to be found in a physically sub-normal body. He definitely proved the exact opposite and it is now known that children who are above the average in mental capacity are also above the average in physical health and strength.

AT bottom of this page is a photograph recently taken by a student-John E. Stewart-of the most northerly situated college in the world, the Alaska Agricultural College and School of Mines. It is situated at College, near Fairbanks, Alaska, approximately on the 65th parallel of latitude, and therefore just south of the Arctic Circle. It is farther north than Hudson Bay, and in about the same latitude as southern Greenland.

Continued discussion of the paper of R. W. Raymond, presented at the Cleveland meeting, October, 1912, and printed in Bulletin. No. 70, October, 1912, pp. 1111 to 1122. See also discussion printed in Bulletin No. 74, February, 1913, pp. 319 to 329. R. B. BRINSMADE, Puebla, Puebla., Mexico (communication to the Secretary *) :-Though I heartily approve of several minor points emphasized by Dr. Raymond (such as the general desirability of local administration, rather than Federal, and the evils inseparable from the Federal Apex Law), I feel obliged to dissent from his four final propositions. As Dr. G. 0. Smith has already discussed these propositions from the standpoint of the experience of other countries, I shall base my criticism upon certain general economic principles, which will be grouped under the following five topics: 1. The dual theory of property. 2. The essential factors in fixing prices. 3. The relation of land ownership to the distribution of wealth. 4. The relation of land ownership to speculation and development. 5. The relation of land ownership to the political power. I shall give here only a brief outline of these topics, as they are fully treated in the standard treatises on political economy.1

(Cleveland Meeting, October, 1912.) UNDER the names of Conservation, Social Justice, the New Nationalism, and Progressive Democracy, many earnest reformers are calling for a new system of Federal government to replace the one which they ascribe to our fathers, and declare to have been outgrown. They are proposing the lease by the United States of certain natural resources on the public domain, for the profit of the U. S. Treasury, instead of the sale of such resources to private citizens or associations of citizens. In the present paper, I shall try to show that this notion is neither new nor good. It is clear that the United States is owner, as well as sovereign, of public lands acquired through conquest or purchase from other nations, as it was owner of the public lands expressly ceded to it by the original thirteen States. Its policy with regard to such lands involves, therefore, two entirely distinct questions: What shall it do as owner ? and, What shall it do as sovereign ? The latter question, it must be confessed, has played but a small part in our history. All the prerogatives of sovereignty which were not explicitly conferred upon the Federal government by the original States were retained by them. The ownership or control of precious or other metals or minerals in the earth, for instance, was thus reserved to the several sovereign States. New York, South Carolina, and other States have passed laws on this subject, without regard to Federal authority. As new States have been successively admitted to the Union, the tacitly accepted theory has been,. that they thereby acquired all the reserved rights of the original States. These newer States largely outnumber the first. thirteen; and it is inconceivable that they would submit to any deprivation of sovereignty based on historical grounds. One of them-Texas-came into the Union by its own voluntary

FREDERICK WORTHEN BRADLEY, the newly elected president of the Institute, may be said to be the prototype of the men who have built up the great mining industry of the West. He was born in Nevada County, Cal., on Feb. 21, 1863, and studied mining at the University of California from 1882 to 1884, as a member of the Class of 1885. He was in contact with the mining industry from his earliest years and in his reminiscences which we published last month, he told of meeting Thomas Mein and H. C. Perkins in 1877. Beginning as assayer and roustabout at the Eagle Bird mine, in Nevada county, Mr. Bradley was a deputy mineral surveyor in 1886 and 1887 and superintendent of the Spanish mine from 1885 to 1890. There he made a record of mining gold ore at 65 cents per ton that was not only astounding in that day when modern large scale mining had not yet been developed but is still a mark to shoot at. As a result he was called in 1890 to be assistant manager of the Bunker Hill and Sullivan and was made manager in 1893. In 1897, he was elected to the presidency of the company, a position he still holds. H. C. Perkins and D. O. Mills, the largest stockholders in the Bunker Hill and Sullivan Co. took over the Tacoma smelter in 1898, feeding it with concentrate from the Coeur d'Alene and Douglas Island mines but also doing a gen-era1 smelting business. Mr. Bradley was put in as president of the Smelting company, and held that position until the plant was sold to the American Smelting Securities Co. in 1905.

PROSPECTING for new deposits is a part of the ordinary routine business of the petroleum industry to an extent that is not true for any other mineral industry. The health of the industry depends upon whether we are successful or unsuccessful. How many know what it costs to find oil today and what it has cost in the past? Very few, I will wager. The industry is not well informed upon this extremely important point. We cannot deal in averages for lack of information. Does it cost more or less than previously? Prospect wells are increasingly deeper and, since the introduction of the core drill, prospecting techniques have required increasingly expensive field oper-

UNDER the stimulus of war psychology the American public has grown confused and jittery in its thinking on the subject of this nation's petroleum resources. This confusion arises from the failure of the average citizen, and even of many leaders in government, in our armed forces, and in the petroleum industry itself, to distinguish between our proved reserves of petroleum in the several oil-producing states and the total petroleum re- sources available to this nation. Leaders and public alike examine the accepted estimates of our proved reserves and thoughtlessly conclude that these estimates represent the total of our petroleum resources. Our fears are aggravated if we turn to the statistics on oil-finding and observe that the discovery of new reserves has waned decidedly in recent years. This confusion is dangerous because, under its influence, ill - considered policies spring up and flourish, choking out the most valuable fruits of the long experience of the American petroleum industry.

EDWIN LUDLOW, president of the American Institute of Mining and Metallurgical Engineers for the year beginning Feb. 15, 1921, is a well-known figure in the state that was the birthplace of the Institute-Pennsylvania-although he was born and educated in New York and is again one of its residents, after years of active work in the field. Mr. Ludlow was born at Oakdale, Long Island, and was graduated from the School of Mines at Columbia University with the class of 1879. After graduation, he became a civilian worker with the U. S. Engineer Corps under General William Ludlow, his brother, and for two years did river and harbor surveying along the New Jersey coast.

ENGINEERING is in essence quantitative, and the engineer must deal with exact figures when he plans and, constructs. Engineering truths are not best expressed by adjectives, yet my wish, today, is not to attempt a quantitative measure of the dominant position of the mineral industry of the United States in the existing scheme of material things, but rather to seek a clualitative appraisal of what mining and metallurgical engineers are doing to promote and make secure our , national progress. Statistics help when we wish to gage material prosperity, but they fail when we desire to determine what share the engineers have in adding to the happiness and welfare of our people

AT the Annual Meeting of the A.1.M.E. last February, Cornelius F. Kelley, chairman of the Anaconda Copper Mining Co., was presented with the Charles F. Rand Memorial Medal for "conspicuous success as administrative head of great enter- prises engaged in the production of nonferrous metals at home and abroad; for inspiring leadership of an organization that has trained able engineers for service wherever ores are mined and metals are recovered; and for enhancing the prestige of metal mining in the financial and industrial world." Mr. Kelley's acceptance speech follows: I am not unmindful of the fact that the distinction is not to be considered a personal one, but that by the language of the citation itself it is rather a recognition of the service that has been performed by the many trained men of an industrial organization that in the arts of mining and metallurgy and in the fabrication of metal products has performed a distinct service to the industry and to mankind. In that spirit, the award is accepted, and on behalf of the organization I represent and myself, I thank you and assure you that the honor is deeply appreciated.

THE Cassidy Colliery operated by the Granby Consolidated Mining, Smelting & Power Co., Ltd., is situated about 9 miles in a southerly direction from the city of Nanaimo on Vancouver Island. The coal seam worked, which is called the Douglas bed, outcrops in the western part of the property, clipping easteyrl, and is opened by a slope 7 by 14 ft. in the clear, and is timbered by 12 to 14-in. framed sets of timber, 4 ft. center to center. A separate manway provides for a traveling road and at the same time forms an intake airway. The general average of the dip of the seam at Cassidy is 18°, and varies in thickness from 1 to 25 ft., averaging about 8 ft. The main slopes follow straight down the dip a distance of 4545 ft. At the bottom of the main slope two rock tunnels were driven a distance of 1500 ft. to the south, cutting through a fault, and opening up an area in the same seam which is known as No. 7 South Section. The coal is found in this section at a vertical depth of 1560 ft., and is very soft and friable. The immediate roof is a strong, sandy shale overlain by massive sandstone while the floor is a light-colored shale, hard when freshly exposed. It does not soften materially oil exposure. In the folding of the coal measures a great thrust caused a movement along the coal seam as indicated by the slickensided nature of the coal. The floor has buckled and this has rolled and squeezed the coal-so that with rare exceptions it shows no normal bedding but curved slip planes, which frequently start at right angles to the floor, curving upward and then in the direction of the dip. As such planes are slickensided it is probable that there is a coating of clay which is more or less impervious to gas.

DEPLETION of anthracite resources in Lackawanna County, Pennsylvania, has forced the recovery of coal tracts formerly considered unminable. Chief among these are the large areas of outcrop coal lying on a heavy pitch on the mountain sides, abandoned thirty or forty years ago as too costly and too hazardous to mine. The old companies, in many instances, stopped their chambers 80 or 100 ft. hack from the actual outcrop, and then dropped back another 100 ft. before starting to rob the pillars, thus leaving large areas of coal. Recovery of this coal naturally leads to mining hazards not encountered years ago. The first step is to sink a slope from the surface with the pitch of the vein, and then drive counters across the pitch as close to the robbed area as proper protection for the lower side of the -counter will permit. Next, the old chambers are advanced or new ones driven in the solid, as the conditions require. As these chambers approach the outcrop the real safety work begins-that of preventing the miner from being buried or locked in by an avalanche of mud.

In the examination of an undeveloped prospect a decision must be arrived at from an inspection of the outcrops and the exposures in a few shallow pits. Prospects that are offered for sale rarely expose any important quantity of good ore, work having usually been stopped when the immediate exploration no longer yielded favorable results. It should be borne in mind, furthermore, that a great majority of prospects have been examined many times, and if of conspicuous promise, would have been acquired-for development. In most cases the problem for the engineer, therefore, is to discover the traces of a valuable mineralization that has disappeared through solution, or the conditions that indicate the possibility, or probability, of underlying secondary enrichments. The available data being meager, every feature should be the subject of careful study-the condition of the outcrop, the structural relationships, the associations of minerals, the alterations of wall rocks, the chances for underlying enrichments, and so forth, as well as the actual assay value of the material exposed. It is frequently advisable to spend the time and money necessary to have trenches dug at various significant points along a promising outcrop; such exposures, even if the depth attained is slight, often disclose conditions that are not apparent at the actual surface, as for example, the existence of soft minerals and the distribution of the various minerals through the mass of the deposit. Trenches also permit samples to be taken from points that were not accessible during former examinations. Strong, persistent outcrops of uniform width may be taken to indicate the probable size and character of the underlying vein,

COMMENTING on the report of the latest Royal Commission for India, the September, 1926, issue of the National City Bank's monthly letter states, among other things, that "The decision of the Royal Commission is against the proposal for a gold coinage, but in favor of placing the silver coins and paper currency now redeemable in silver on a gold basis." Also, it quotes the following from the Royal Commission's report: The essence of the proposal * * * * * is that the ordinary medium of circulation in India should remain as at present the currency note and the silver rupee, and that the stability of the currency in terms of gold should be secured by making the currency directly convertible into gold for all purposes, but the gold should not circulate as money. It must not circulate at first, and it need not circulate ever. In this connection it may be stated that during the last one hundred and fifty years or so unsuccessful attempts have been made by the governments of different nations of the world to devise a plan or plans by which gold and silver could be used concurrently for money purposes and, particularly, as standard money; such, for example, as bimetallism, which, of course, is impracticable. But, since none of such plans has been adopted generally it is logical to conclude that their proponents did not shape them so as to conform to the basic principle of standard money, or else political issues were deemed to be dominant, or, perhaps, it was partly due to each.

UNDER the name of the Russian Far East we understand the territory occupied by the Amur, Maritime, Sakhalin and Kamchatka Provinces, the total area of which is about 918,000 square miles. The mining industry took its first step in the Russian Far East in the second half of the 19th century, and until the end of this century was restricted to gold placer mining. In the last years of the 19th century, the extraction of coal and lignite was begun, and in 1910-11 the exploitation of silver-lead-zinc mines. The conditions of the Far Eastern mining industry during the last few years may be outlined by the following figures. Annual production of gold mines was about 54,000 lb., valued at $13,000,000. During the period of 1910-15 a considerable increase of placer-gold mining by mechanical processes took place; in 1910, by means of dredging and excavators, 500 lb.. of gold were obtained; in 1914, 2740 pounds. Annual output of coal; lignite and. silver-lead-zinc ores was: 1911 1920 Bituminous and semi-anthracite coal, long tons 270,000 316,000 Lignite, long tons 66,000 205,000 Silver-lead-zinc ores, long tons 28,400 94,500 In other branches of mining in the Far East, only the quarrying of building stone and clay may be men-tioned, the total yearly output amounting to about $500,000 in value. The principal gold mines are in the Amur Province, in the systems of the Zeia and Bureia rivers, and in Kamchatka Province, near the town of Okhotsk. The above-mentioned tonnage of coal and lignite was extracted from the mines in the Maritime Province, near Vladivostok. The only silver-lead-zinc mine worked was that of Tetiukhe, near the Tetiukhe Bay, 240 miles northeast of Vladivostok. The ores of this mine were exported to Germany, Belgium, and Japan, partly raw, partly calcined.

During the past year, a number of significant events have occurred in the nuclear industry. These include a surge in nuclear power plant orders, delays in nu- clear plant licensing and construction, increased environmental concern and the new Atomic Energy Commission nuclear fuel policy. These events, particularly the AEC stockpile release policy, have lead us to take this opportunity to update National Nuclear Corp.'s (NNC) appraisal of the outlook for the U.S. uranium industry.

Tunneling is at the threshold of a new era. An exciting new technology is becoming available. And, supplying the increasing quantities of minerals required by a growing and socially advancing world population, together with providing the subsurface facilities attendant to the rapid urbanization of the more developed countries of the world, will require underground excavation during the next decades on a scale that would have seemed fantastic a few years ago. It is estimated that world mineral consumption will increase fivefold by the year 2000. Projections for the United States indicate that domestic consumption of nonfuel minerals may increase two to three times by the end of the century. Meeting these requirements will entail opening up many new underground mines, even if present trends toward surface mining continue. And, at least in the United States, new factors that are becoming increasingly important may modify these trends. We are depleting our shallow easy- to-find and easy-to-mine mineral deposits; and, if we are to avoid becoming dangerously dependent on imports, we must turn more and more toward deeper deposits that are not amenable to surface mining. Growing public concern with environmental quality is apparently leading toward increasingly stringent regulation of surface mining which also will tend to make underground mining economically more attractive. The world market for underground construction is also growing rapidly. The most conservative projections indicate that in the United States alone more than $7.0 billion will be spent on excavation for underground facilities during the next ten years. And these estimates do not include any of the bold, imaginative new applications for underground excavation that have been proposed, such as extensive underground power transmission, the Chicago Deep Tunnel plan, and the Northeast Corridor Transportation project. There can be little doubt then that the market for tunnels for conventional applications is increasing rapidly and that the trend will continue. It
