THE West Indies are the summits of a submerged, mountain chain, the continuation of which must be sought in the mountains of central Honduras. In Haiti, the chain divides, one branch passing through Jamaica and the other through Cuba, the Cayman Islands, and the Misteriosa bank. Suess divides the West Indies into three zones: The first zone is entirely of volcanic origin and includes many recent volcanic cones. It includes the arcùate string of islands, which extends from Saba and St. Kitts to the Grenadines and Grenada. The western half of Guadeloupe belongs to this group. The second zone consists of a geanticline, of which the sedimentary rocks range from the Jurassic to the Quaternary, but consist chiefly of Lower Tertiary sediments. In the west it is broad, including the whole of the Greater Antilles; but in the east it is restricted to a narrow belt, which includes the Virgin Islands (except Anegada), Anguilla, St. Bartholomew, Antigua, the eastern part of Guadeloupe and part of Barbados. The islands that compose the third zone are flat and low. Like the second, this zone is broad in the west and narrow in the east; it includes the Bahamas, Anegada, Sombrero, Barbuda, and part of Barbados. Geologically, Florida and the plain of Yucatan may be regarded as belonging to it. Trinidad and Tobago, though-geographically adjacent to the Lesser Antilles, are geologically a detached part of the South American continent. The crystalline complexes of northern Trinidad and of Barbados are a continuation, en echelon, of the crystalline axis of the promontory of Paria. The folded Cretaceous and Tertiary of the central and southern parts of Trinidad represent a continuation of the folded sediments of the Paria district of Venezuela.

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.

ONE of the most unusual features in connection with the strike of the union coal miners in the bituminous fields, now in its sixth week, is that the public interest seems to have completely died out. There is nothing on the front page and very little on any other page of the daily newspapers in connection with the strike. The United Mine Workers' officials must be rather disappointed to find that the only way in which they are being featured in the papers at present is in the reports of the trial for treason that is going on in Charlestown, West Va., against the local leaders of that organization for their responsibility in connection with the attack of the miners' army last summer against the non-union mines of Logan and Mingo Counties. Recent reports state that there are 13,000 cars of coal standing on the sidings at union mines for which no billing has yet been found. The output of the non-union mines has been gradually increasing but has never reached the maximum that they are capable of producing, owing to their inability to obtain enough orders to make it possible to run full operating time. The, present output is estimated at, 4,500,000 tons a week. It is possible, with a full car supply and full demand, to bring this output up to approximately 6,000,000 tons per week, and it is very doubtful whether, at this season of the year when probably there is less consumption of coal than, at any other season, the requirements of the country are greater than the 6,000,000 tons which the non-union mines are capable of producing. It would appear, therefore, that there is no immediate prospect of any settlement of the bituminous strike, and there is certainly no reason why the operators of the union mines should show any anxiety to begin operations as long as they have unbilled coal standing on their sidings.

A CANVASS of the various institutions known or suspected to be giving courses dealing with petroleum and gas revealed the courses listed in the accompanying table, which includes a summary of the number of class hours, as a whole, of the courses listed. It will be observed that the situation is grati-fying. Courses are presented in different institutions in the main geographic sections of the country, so that students have no difficulty in obtaining education in this field. The committee believes that the courses that are offered in many institutions are so inadequate in amount as to make it unwise for students who have not had additional work to consider themselves trained in this field. We strongly urge the few schools now presenting the most adequate courses to develop these more fully, bringing their work up at least to 300 hours, and let other schools concentrate their energies in other fields.

COLOMBIA has an almost ideal situation with respect to the world's markets, being only a short distance from the Panama canal and the West Indies. The sailing distance from its Caribbean ports to New York is less than that from Tampico. Geographically, Colombia consists of three systems of broad mountain ranges separated by two long narrow valleys. The Cauca River valley separates the Western or Coastal range from the Central range. On the west side of the Coastal range are the Atrato and San Juan Rivers. The Central and Eastern ranges are separated by the Magdalena River valley. In the department of Santander the Eastern range divides, one branch continuing northward as the Cordillera of Perija, the other turning eastward across Venezuela as the Cordillera of Merida. Between these ranges is the great basin occupied by Lake Maracaibo. These valleys consist mainly of long narrow reëntrants or tongues of Tertiary sediments between the older rocks of the mountain ranges. The late Miocene and younger sediments seem to have been deposited in separated basins, but the Cretaceous and possibly some earlier Tertiary strata were laid down more or less continuously over a great part of .Colombia and Venezuela. These strata were subsequently folded into the present ranges. The deposition of the Cretaceous and of some of the Tertiary was in a great sea, the main land mass being in Brazil, with land probably along some of the cores of the present mountain systems. The sediments, except the Lower Cretaceous, vary markedly in character and thickness. An illustration is seen in the massive series of non-marine conglomerates and sandstones of the upper Magdalena River valley, near Honda, which are almost wholly wanting in the coastal sections where marine sediments prevail. The oldest rocks bearing on the search for oil are the black carbonaceous and bituminous shales, limestones, and cherts of the upper part of the Lower Cretaceous. These probably are the main source of oil in both Colombia and Venezuela. They include thick bodies of true "oil shale. Above the carbonaceous and bituminous beds, lies a series of many thousand feet of clastic sediments. The most noticeable and easily recognizable formation among these clastic sediments is the "coal-bearing series," which may be either upper Cretaceous or Eocene. The

THE bases of the work by the committee whereof I am chairman were (1) the abolition of extra-lateral rights and (2) the preservation of the maximum of the existing laws. The matter of extra-lateral rights had been under prolonged discussion among mining men and up to the time when our com-mittee began its work (in 1917) the expression of opinion in every way whereby it could be made known -and those ways were extensive-was only a little short of being unanimous that extralateral rights ought to be abolished. I have not observed important evidence indicating a change of opinion on the subject since 1917. ABOLITION OF DISCOVERY LOGICAL Now, when it be decided that extralateral rights ought to be abolished, there can not be merely a simple change to that effect, but it is found that consequential changes are necessary all the way through the existing laws. Abolition of extralateral rights implies abolition of discovery as a prerequisite to location, for otherwise there would be no legal means for locating claims on the dip of a vein. Quite apart from this consideration, abolition of discovery as a prerequisite to location is supported by other good reasons. Among these are the occurrence of orebodies with no exposure on the surface and which often are hidden at great depth. A prospector who has reason to suspect the occurrence of such an orebody must have legal means for the location of a claim within which to explore, and obviously he may. not be able to make any discovery on the surface sufficient to locate and hold legally such a claim under the terms of the law as it stands at present. As a matter of fact, discovery as a prerequisite to location was abolished by common consent many years ago, not only for the reasons that I have given here-inbefore but also for others. It is highly desirable to revise the mining law in this respect, so that it will conform to the conditions of practice and not require people to perjure themselves in making locations, even if it be for praiseworthy purposes.

IN OPENING the symposium under the auspices of the Petroleum and Gas Committee of the American Institute of Mining and Metallurgical Engineers, I wish to call to your attention the following, among other subjects, which it is hoped may receive proper attention: 1. The recording of as accurate an appraisal of the oil possibilities of the various countries as is possible, with information as to the immediate availability of their supply. 2. The development of further support for the move-ment to bring about active cooperation among Ameri-can oil companies in their foreign exploration and development work. 3. The furtherance of the efforts of the industry in securing governmental assistance in foreign oil develop-ment: (a) along the lines of a modification of our domestic oil policy, so that we can go to foreign coun-tries and consistently ask fair treatment as to royalties and bonuses; (b) by a closer cooperation between the State and Commerce Departments and the oil industry. 4. The calling of attention to the unjustifiably drastic action of the price-fixing group of the oil industry during the last year or so, with the hope that it will use gentler methods in the future. None of these subjects are new, and some of them have been discussed before various organizations for years. Our justification for again bringing them forward is the hope that by everlastingly harping on them the industry, the Government, and the people who shape the destinies of this country may some time, some how, realize their importance and take effective constructive action.

THE wage rates and working conditions in the anthracite. region of Pennsylvania have been governed for nearly 20 years by the award of the Anthracite Coal Strike Commission, appointed Oct. 16, 1902, by President Roosevelt. The report of this com-mission, made in March, 1903, was accepted and, with eight modifications made at various dates, has had .almost the force of law, and has kept this great indus-trial region free from strikes for almost a generation. In 1920, President Wilson appointed an Anthracite Coal Commission, and its report, accepted Aug. 30, 1920, governed wage conditions to April 1, 1922. Actually, the agreements have been for terms of two to four years, and lately, in 1916 and 1920, the employ-ees have continued at work pending the negotiation of new agreements which were made retroactive, and which have all been modifications of the original 1903 award. With the expiration, April 1, 1922, of the 1920 award approaching, Mr. Lewis, president, of the United Mine Workers of America, addressed a letter, on Feb. 20, to the operators, suggesting a meeting on March 15; this date was accepted by the latter, with the notation that the time was short. At the meeting, the Mine Workers presented 19 demands, and advised that if a satisfactory agreement was not reached by April 1.a suspension of mining would occur, contrary to the practice since 1916 of continuing work with a retro-active adjustment.

LEASING the Teapot dome to the Mammoth Oil Co. is the culminating anticlimax of the "conserva-tion movement." It is just the touch required to make a full fiasco of the whole affair. If the revered wielder of the "Big Stick" were still with us, we could hear it fall harder than it did on Ballinger. Of all the oil reserves set aside by presidential decree, there was only one which certainly could con-serve much oil for the future. This was Naval Reserve No. 3, on the Teapot dome, Wyoming. After secret negotiations, carefully guarded from the press and from the knowledge of other oil men, we are suddenly informed that this last and only known chance to save much oil for future naval needs has been given away for early development.

MAY began with a general strike of the bituminous and anthracite coal miners in the United States in progress, while in Great Britain about three quarters of a million workers became idle by a lockout, caused by a dispute respecting the question of the rights of management in their shops. The employers opened their shops on May 3 to men wishing to resume work, but few availed themselves of the opportunity. Up to this time the statistics had been showing a little increase in the rate of employment in Great Britain and business conditions were considered to be improving. From Russia came reports that the results of the famine had not been so bad as had been prophesied, which is not to say that they were not grievous. In prognostications such things are habitually overesti-mated. Seeding for the new crop has now begun in Russia, with hopes for better results than last year. However, the general economic situation in Russia steadily becomes worse. We had advices during May to the effect that the Soviet Government had decided to abolish the gold ruble even as a theoretical calculating unit and substitute a "goods index." This idea would be somewhat on the lines of Professor Fisher for stablizing the dollar, and there may be a chance to see how it will work in practice. There was a contradictory report from Russia, however, that it had been decided to revert to the gold basis. This is the more plausible report, for if there be anything to be deduced from economic theory and history the present paper rubles will completely collapse and return to gold basis will ensue simply because the people will refuse to sell their goods on anything else. The civil war in China came to a head during the first week in May when General Wu-Pei-fu crushed the forces of General Chang Tso-lin around Pekin. The victor declared his intention to be to reunite the North and the South and in course of time to arrange for a constitutional convention. We probably do not under-stand the conditions in China, but recent events do not appear to have solved the grave difficulties there, though they may be a step toward it. However, the immediate outlook does not appear good, General Chang having retired to the north and declared the secession of Manchuria and Mongolia.

THE submission of carefully prepared estimates of the oil reserves of the United States calls for no apology or explanation. In this country, petroleum is a rapidly wasting asset and an occasional appraisal of the amount remaining in the ground is a simple business procedure to safe-guard the general welfare and the prosperity of the republic. The rumored danger of failure, in the near future, of the foreign supply on which we depend in constantly increasing amounts makes the immediate review of our available reserves the more imperative. The Director of the U. S. Geological Survey, in March, 1921, requested the American Association of Petroleum Geologists to cooperate in the preparation of new estimates of the oil remaining in the ground. With the members of this cooperative committee, state geologists, regional geologists, consulting specialists, and geologists and engineers attached to many companies worked both independently and through sub-committees. The reports for districts, counties, fields, etc., after review by local or state committees, were discussed by the joint cooperative committee in conferences that, in some instances, were attended by the original compilers of estimates for the states or smaller areas. Finally the data were reviewed and the figures revised by the joint cooperative committee, so that the totals given in Table 1 represent the opinion of the committee, which was composed of F. W. DeWolf, W. E. Wrather, Roswell H. Johnson, Wallace A. Pratt, Alexander W. McCoy, Carl H. Beal, C. T. Lupton, G. C. Matson, K. C. Heald, W. T. Thom, Jr., A. E. Fath, Kirtley F. Mather, R. C.

IT IS universal practice for corporations, at the end of the fiscal period, to call in a firm of chartered accountants to audit the books. The effect of this is to put an independent organization's seal of approval on the accounting of the business done by the management. Their report lets the stockholders know that the accounts rendered truly present the results of the year's business. This is as it should be; the average stockholder has no personal contact or even acquaintance with the managers of his enterprise and the approval of their stewardship by an indepen-dent agent is very desirable for maintaining confidence in their honesty and ability. But such an examination deals only with what may be called the arithmetic of the business; even the most elaborate audit, as the practice is at present, goes no further than to verify the items of the inventory. In other words, while checking up the entries showing the transaction's of the year and certifying to the correct-ness of the items of the balance sheet, such a report gives the stockholder no idea of the ability with which his affairs have been managed. If the profit and loss balance is satisfactory, as certified by the public accountants, he assumes that the management has been able; where it is not, he turns to the president's report and usually finds an explanation. Such an explanation never takes the form of admission of mis-takes in business judgment or of bad technical manage-ment. It could hardly be expected that it would. The stockholder is generally furnished, therefore, with a certificate of the honesty of his management, but never one of its ability. He does not worry about the latter as long as dividends come in; when they cease, his action generally finds expression in replacing the management. In other words, so long as profits are realized, he assumes the management to be good, even though its success is a matter beyond its control and better management would make larger profits. When there is no profit, the stockholders have no means of knowing whether it is due to conditions beyond the control of the management, as the annual report is sure to allege, or whether, by better management, profit is possible. Here is where the technical audit comes in.

FIVE of the geologic horizons that yield oil in other parts of the world are represented in Brazil; namely, the Devonian, Carboniferous, Permian, Cretaceous, and Tertiary. Thus far, the first two have shown no, evidences of being oil bearing within Brazilian territory. Not enough exploring has been done to permit trustworthy comparisons of the relative importance of the Permian, Cretaceous, and Tertiary as oil-bearing horizons in this country. The most important, indeed almost the only, information available relates to the locations of the areas and to the structural features of the several horizons. The theories regarding the physical conditions under which these rocks were laid down, however, I regard of the utmost importance. PERMIAN Rocks of Permian age cover an enormous area in Brazil, extending from Rio Grande do Sul to Maranhão on the north, and to Matto Grosso on the west. These Permian rocks in many places are known to include oil-bearing shales and in some locations contain small veins of gilsonite. The geologic map of Brazil shows that the Permian area is widely distributed, but there is considerable doubt about 'the origin of some of the rocks:. Some of the lower Permian beds in southern Brazil contain marine fossils, but in Minas no fossils have as yet been found in them, and in Bahia, at only one locality have a few Permian plants been found. Indications of oil have been found in the states of São-Paulo, Paraná, and elsewhere farther south, but wells drilled in the Permian of São Paulo near the Morro do Bofete did not find oil. One well has been started, by the Brazilian government, in the Permian of Paraná near Marechal Mallet, close to latitude 26° south, but thus far oil has not been found.

THIS paper gives the results of an investigation of the specific resistance and temperature coefficient of the electrical resistance of nickel and its important alloy, monel metal. For most of the pure metals, the temperature coefficient of resistance is approximately 0.0004 per degree centigrade at 2.0° C. Nickel and iron, however, are exceptions. This property is important as it gives us good material for the construction of thermometers and other instruments involving electrical control. A summary of information on this subject has been published by the Bureau of Standards.1 The present experiments antedate this publication by several years and as the information obtained is not contained in it, the results of the experiments are published as additional information. ELECTRICAL PROPERTIES OF PURE NICKEL It is generally conceded that the lowest values for electrical resistance are obtained in the purest metal. In the case of nickel, the best material obtainable is electrolytic nickel, which contains approximately. 99.80 per cent. nickel, 0.15 per cent. iron, and 0.05 per cent. copper. Any cobalt that may be present is included in the nickel figure. If the electrolytic sheet has been deposited without intermission, it is possible to cut a section from the sheet and roll it into wire without melting. By this means a nickel wire may be obtained that is uncontaminated by any of the impurities always taken up by nickel during melting.

IN CONSIDERING the question of mining methods the possible rate of production deserves much more attention than it often receives. Hoover's theorem that, in order to show the greatest profit, an orebody should be worked out in the shortest practicable time, should be better known. The author recently' obtained detailed statements of costs from iron-mine superintendents of the Lake Superior district. In discussing these, the effect of rate of mining on cost of production was considered and detailed estimates were made. The methods by which these estimates were made and the way in which they were presented are here described to illustrate the importance of this factor in mining operations. The saving due to lower costs is not the only factor that should be considered. The greater profit per ton is of much importance but of equal importance are the greater profit per ton that will be made on a greater number of tons per year, and the fact that the total profit will be received in a shorter; period. This last makes a great difference in the present value of a property, by shortening the period of discount on future profits. Another item of importance to those operating a number of mines is that the tonnage needed to supply the market can be obtained most profitably by operating the smallest number of mines that will supply the amount required when each is worked to maximum capacity. In the Lake Superior iron district there are many grades of ore, and the requirements for each are known. If the demand for a certain grade can be supplied from mines now operating, the development and mining of a new orebody of the same grade must result in lower rates of production and lower profits to all mines producing this grade. If a company is mining the same grade of ore from three mines when it can supply its needs by operating only two, by operating only two it can obtain the greatest profit. Royalty rates, lease terms, and other considerations modify this general statement, but if all three properties

MARCH 31, 1922, undoubtedly will be long remembered as the ending of an important epoch in the coal-mining industry. On that date, contracts fixing the wages and terms of employ-ment at all anthracite mines and at approximately 60 per cent. of the bituminous mines of the country expired. For the past two years, the consuming public has been complaining bitterly against continued high cost of coal. Coal operators employing union labor have felt obligated to carry out contracts entered -into under the direction of the Bituminous Wage Commission appointed by President Wilson, and in order to do this, they have sacrificed millions of tons of business to non-union mines, and millions of dollars in wages that would have been distributed throughout unionized districts have been diverted to the non-union miners, many of whom never obtained the peak wages granted by the Bituminous Commission and others of whom accepted reductions early in 1921. Heretofore, wage contracts have overlapped as to expiration dates in different districts and renewals have had to take into consideration the competitive balance; the present situation is unique in that practi-cally every contract in the country expired on March 31, and the questions now confronting those responsible for the operation. of the coal mines of the country are: 1. Shall the operators that have heretofore employed union labor endeavor to continue contractual relations with United Mine Workers of America? 2. Shall they undertake to operate their mines with non-union labor? 3. Shall they encourage and endeavor to work out some plan of regulation or arbitration by a Government commission such as President Roosevelt appointed to settle the anthracite strike in 1902? 4. Shall the country give consideration to the demand of the miners that the coal-mining industry be "nationalized?"
