Report of the Americanization Society, New York Section During the past two months the Americanization Committee has held social meetings of various kinds for foreign-born women, as a preliminary to future effort along the lines of Americanization work. At the same time, a thorough investigation was made as to the work being done in New York by organizations devoted to this interest. The committee will be very glad to help any other committees being formed, in mining centers, with advice and information that has been gathered together as to classes and meetings of all kinds best suited to the needs of a foreign-born population. The work has been so extensively taken up in New York that for the present it would seem to be, for this committee, the most profitable and interesting work to continue the social meetings and to undertake the care of one or more immigrant families, to be friend and adviser in joy and sorrow, work and play, and in this way do some fundamental Americanization work. Respectfully submitted, LAURA G. BURGER, Chairman.

ONE of the interesting features connected with the great continental uplift, which formed the table land of Mexico, is the great depth to which oxidation and secondary enrichment of orebOdies occurred. This table land lies at altitudes ranging from 4000 to. 7000 ft. (1219 to 2133 m.) above sea level. Several cases could be cited of oxidized zones in copper and lead mines which reached depths of upward of 1500 ft. (457 m.) below the surface, and it is universally admitted that the oxidized zone in a mine is limited by the permanent water level. FIG. 1. Mexico, however, like many other countries in which deserts occur, is visited at rare intervals by tremendous floods, which sometimes cause variable water levels over long periods. The following cases bear out the idea, and lead to interesting conclusions of commercial value. My paper demonstrates that carbonates of ores may occur below water level and sulphides above, and I will endeavor to explain the causes of the phenomena in certain specific instances.

Typical System of Workings THE general system of workings at the Utah-Apex is similar to that found in many of the western metalliferous mines. There is a vertical three-compartment shaft extending to the surface, from which the various levels have been driven to the orebodies. The 1000-ft. (305-m.) level, about ¾ mile long, was driven as a haulage and drain adit. Geology The formation is a flat north-dipping series of alternating limestone and quartzite beds. Extensive north-south faulting and-fissuring have taken place, resulting in the formation of large replacement orebodies in the crushed zones in the limestone. The orebodies are irregular in shape and size, but follow closely the trend of the mineralizing fissures. The ore consists of galena, pyrite, sphalerite and small values in silver and gold. Large masses of non-commercial pyrite are frequently found in or adjacent' to the orebodies, and more or less pyrite is found for some distance in the walls of the orebodies. Lenticular bodies of a black pyritic shale also occur in the zones where extensive faulting has taken place.

The fifth convention of the National Foreign Trade Council was held in Cincinnati, Apr. 18, 19 and 20. More than one thousand accepted delegates were registered, the American Institute of Mining Engineers being represented by W. L. Saunders and W. N. Thayer. The convention was called to order Thursday morning, Apr. 18, in the convention hall of the Hotel Gibson; by the Chairman, Mr. James .A. Farrel, president of the U. S. Steel Corporation, and was in continuous session for two clays, several group sessions being held simultaneously. The convention adjourned Saturday morning after receiving the report of the central committee. The dominant themes of the convention were: First, "Win the War" and second, "Establish Foreign Trade on a. Firmer Basis." The discussions included textiles, lumber, chemicals, automobiles, finance, and agriculture, and also those things in which mining engineers are particularly interested, metals, oil, and coal. The report of the central committee, which was adopted, recommended the stimulation' of production of all materials required for war purposes; the subordination of all trade that will not impose new and heavy penalties on our adversaries; the maintenance of such foreign trade as will support national credit and supply materials required for military and naval purposes; the continued interchange so far as possible of merchandise and products between the United States and. Latin-America, Asia and Oceania; the immediate increase of tonnage in the north Atlantic; the cheerful and whole-hearted cooperation of importers

John R. Lucas was born Apr. 15, 1866, at St. Louis, Mo. From his 19th year until his death on his 51st birthday anniversary, he was engaged in the mining industry, in which, however, he made his beginning and achieved his progress after a somewhat unusual fashion. Presumably without previous training as a mining engineer, he became in April, 1885, and remained until the end of 1892, bookkeeper of the Granite Metal Mining Co. at its St. Louis office. Then for a year he served as bookkeeper of the same company at its mine in Montana. This official of a mining company is at the very heart of its operations; and if he possesses ambition and intelligence, may learn the business thoroughly. It is not surprising, therefore, that Mr. Lucas, being that kind of man, assumed, in 1894, a position with the Hope Mining Co., another St. Louis corporation operating in Montana, which he retained for eight years, serving not only in the office, but becoming also successively mill foreman and assayer. This varied practical experience prepared him for important administrative functions. From April, 1902, he was for many years the business agent of the Goodhope Mining Co. In 1903, he became also the assistant superintendent of the Granite Bi-metallic Consolidated Mining Co., and subsequently its superintendent-a position which he retained until his health failed at the end of 1916. In addition to the other Granite Bi-metallic properties, he had charge of the sapphire mines in the west fork of Rock Creek, Mont., the Basin Gulch placer mines, the claims of the former Hope Co., etc., all of which he managed with skill, integrity and recognized business ability.

J. B. MCGRAW, New York, N. Y. (written discussion*).-In Mr. Burke Baker's description of the process of the American Briquet Co., he speaks only of the attractive features, but every process which uses a compound or emulsified binder has certain undesirable features which must be considered. In making an emulsion, the success of which depends upon the introduction of the various ingredients at certain fixed temperatures and the complete intermixing of a soluble solution with an oil which has absolutely no affinity for it, considerable difficulty is found in keeping the various factors in strict accordance with the formula. To serve its purpose properly or, in other words, to be right for easy mixing with the coal, it should be of a certain predetermined density. Among the controlling factors of this ate the proportion of moisture contained and the temperature of the oil when introduced. If the latter is higher than intended, a greater proportion of moisture will be evaporated than is proper, and if the oil is not sufficiently hot the process of emulsification is retarded. These various factors can be controlled with more or less certainty where working in a laboratory or in a small experimental way, but when it is attempted on a large commercial scale, certain obstacles not otherwise apparent are likely to be encountered.

I. INTRODUCTION VOLCANIC origin. was among the first of the theories advanced to account for the occurrence of the salt domes of the Gulf coastal plain, northern Louisiana., and eastern Texas, and it is still being re-stated in various forms by the most recent contributors to our knowledge of the geology of such deposits. Argument has been largely by analogy and attention has repeatedly been called to the Mexican oil fields, particularly those of the Tampico-Tuxpam region, because of the occurrence of oil in close proximity to volcanic plugs in those fields, an occurrence supposed to have some resemblance to the common occurrence of oil in the salt domes of the United States. The author, having spent several months of the past year in a general study of salt domes and in a detailed study of certain domes in the United States, and having been acquainted for some time with the exploration of similar domes in the Isthmus of Tehuantepec region, Mexico, and with the general geology of the Tampico-Tuxpam region, Mexico, has reviewed the various theories of volcanic origin for salt domes which have been advanced to the present time. The purpose of this paper is to present such review and to discuss the supposed Mexican analogy.

The German Kaiser is employing the keenest engineering talent of his own and allied empires in his attempt to defeat the world. American employers are paying engineers such attractive salaries that voluntary enlistments of high class technical men in the United-States Army, are below requirements. This deficiency is also probably due in part to the lack of proper information concerning the engineering branch of the service. Few civilians know that it is possible for them to perform in the Engineering Corps almost exactly the same kind of work as that in which they are now engaged. The best results in any organization are obtained only when the energy of every man in it is concentrated along the line for which he is best suited by natural ability, education, and training. It. is more important to have the right man in the right place in our Army, where lives of men are at stake, than it is in any business enterprise. The First Replace meat Regiment of Engineers was organized at Washington Barracks, D. C., on Dec. 14, 1917, with the express idea of accomplishing this. end. Its specific, purpose is to keep all engineering units of the Army at full enlistment strength during the period of this war. This regiment has not only the responsibility of finding men to fill depleted ranks, but it must also fit them to step into the work of trained, efficient and disciplined soldiers. The preliminary work of the recruit is first a thorough training in military drill, for the engineer soldier must be prepared to lay down his shovel and take up his rifle at any time. Infantry drills gradually give way to engineer work and more specific technical training. The. engineer soldiers must know how to tie knots and lashings, to build spar and truss bridges, to construct revetments, dig trenches, place wire entanglements, construct machine-gun emplacements, build pontoon bridges, and to construct roads: They must, also know the methods of demolition, sapping, and mining. Specialized training in lithography, zincography, surveying, mapping, photography, carpentry, blacksmithing, electricity, and machinery, are also given to those qualified for further training in any of these branches. Engineers are called upon to perform such a wide range of work that practically every man with any technical training or mechanical ability can find a place in this organization. Every male citizen in the United States who is physically fit, and between the ages of 18 and 21, and 31 and 40, is eligible to join the regiment by voluntary enlistment.

GEORGE S. RICE (written discussion *).-An interesting and important question arose during the coal famine of last winter as to whether the development of new mines should be discouraged on account of the need of labor for the necessary construction and development work at a time of scarcity of labor, more especially as there was an apparent overcapacity of existing mines. The question was referred to the author for his comments, which led to the study of the statistics. The essential results of this study are indicated on the accompanying chart, which illustrates, among other things, the increase in production or consumption, and the estimated maximum production capacity of the bituminous and sub-bituminous mines of the United States. The curves shown are based on data published in the "Mineral Resources" of the United States Geological Survey, and cover the period from 1900 to 1916 inclusive. The following curves have been drawn from the data secured: 1. Average number of days that the mines worked. 2. Yearly total production of bituminous and sub-bituminous mines. 2a. Yearly production of machine-mined coal. 3. Average annual production, equivalent to consumption, for a period of 17 years. 4. Number of coal mine employees each year. 5. Estimated capacity of mines, on basis of 300 working clays in the year. 6. Estimated drop in capacity if no new mines are opened. Considering these curves and the data from which they were constructed: It will be noted that the average number of days the miners worked varied from 193 in 1908 to 234 in 1900, the average being 217. The causes for so many idle days out of the possible total number of working days in the year are well known, namely: (a) Lack of business; (b) lack of cars. Taking the country as a whole, (a) is the important factor, which might otherwise be expressed as being an excess of productive capacity. The yearly production of the mines, which is practically synonymous with consumption, has shown a steady increase, with a few set-backs. An average line has been struck which indicates that the average annual increase of production has been 18 million short tons (16,330,000 metric tons).

THE great activity with which the oil resources of the northern Cantons of the State of Veracruz have been developed has largely resulted from the great success obtained by the important explorations carried out since 1902 in the Ebano district in the North, and several years later near Tuxpam, in the South. It must not be thought that these successes were quickly obtained, since the preliminary studies by good experts, the acquisition of what were thought to be the most promising coast lands, the extensive clearing thereof, and finally the number of unsuccessful drillings at great depth, signified an original outlay of some ten's of millions of dollars before finding commercial oil. The discovery of oil in industrial quantities at Cerro de la Pez, Ebano district, and the famous Dos Bocas gusher some years later, which was burned, once and for all made famous the Veracruz coast, where today is concentrated the Mexican output of mineral oil. In .1917, this production was nearly 50,000,000 bbl. It is well known that this output represents only a fraction of what the wells in actual production can furnish, because with adequate means of transportation and storage, the present extraction could be somewhat over 300,000,000 bbl. a year. These enormous potential oil resources of the Veracruz coast proceed from a relatively small number of wells, scattered over a few oil fields, separated from each other by large unexplored areas, wherein may be found other favorable fields which, in time, will undoubtedly become just as great centers of oil production. Experts who know our Gulf Coast believe that lands with commercial oil resources lie not only between the Panuco amid Tuxpan Rivers, but that indications are that the oil zone of Mexico, with more or less interruption, takes in the coast zone from Northern Tamaulipas to the foot of the Sierra Madre of Chiapas, and the banks of the Usumacinta River. This generalization is not merely the outcome of optimism, but is the result of the persistency with which one finds, throughout this Gulf Coast, the most usual characteristics upon which we depend for recognizing oil-bearing lands.
