This YEAR BOOK, which is sent to every member, contains the roster of officers and the principal standing committees, brief summaries of the proceedings of the Annual Meeting and of the regional and divisional meetings, abstracts of papers published during-the-year, and a classified list of TECHNICAL PUBLICATIONS and CONTRIBUTIONS, as well as an index of all material published by the Institute in 1935 in these separate forms, in TRANSACTIONS and In MINING AND METALLURGY, the monthly magazine. The two volumes published for the Seeley W. Mudd Memorial Fund are also represented by many items in the index. The necrology, which has appeared in the YEAR BOOK for two years past, will be pub¬lished in the. DIRECTORY, in the spring of 1936. Four volumes, 114 through 117, of the TRANSACTIONS are 1935 publications,-the subjects being, in the order named, Petroleum Development and Technology, Mining Geology, Iron and Steel, Founding and Metallography of Nonferrous Metals (Institute of Metals Division). The Mine Plant volume, which was authorized for publication by the Rocky Mountain Fund, and which was offered as an alternative to a TRANSACTIONS volume, was unavoidably delayed. It will, however, be published as a 1935 volume, and will be distributed as early as possible in 1936. The sixth volume in the A.I.M.E. Series, published under the auspices of the Seeley W. Mudd Memorial Fund, is Coal through the Ages, by. Howard N. Eavenson; the seventh, Modern Uses of Nonferrous Metals,. which has twenty-two authors and was edited by Dr. C. H. Mathewson. Also, it was necessary in 1935 to have a second printing of the first Rocky Mountain Fund volumes, published in 1933-The Porphyry Coppers, and .Ore Deposits of the Western States (Lindgren Volume). The papers for the Iron and Steel and Institute of Metals Divisions have been issued as TECHNICAL PUBLICATIONS distributed under the binding Of METALS TECHNOLOGY in the months of January, February, April, June, August, September, October, December. This plan of distribution will be continued in 1936 for these two groups.

I take pleasure in transmitting herewith "Petroleum Development and Technology in 1927," in which we have attempted to set out in a series of 40 papers with attendant discussions the advances made in Production Engineering and Refinery Engineering during the year. The volume also contains a digest of round table discussions on Petroleum Engineering Research problems and Petroleum Engineering Education. In addition to the above we set out in 16 papers a review of production of each producing area of the United States and of the more important foreign countries, together with a review of the world's production and forecasts for 1928. We also include 8 papers on the Economics of the oil industry. The papers and discussions included herein represent the contributions of more than 200 engineers, including the foremost in each line. These papers were presented at technical sessions held in Fort Worth in October, 1927, and at the annual meeting in New York in February, 1928. We desire to express our thanks and appreciation to all those who have contributed to this volume. As in previous years, we have attempted to emphasize the value of both written and impromptu discussions. -We have made a practice of returning all impromptu discussions to the authors for correction and amplification, and because of this practice we feel that the discussions contained herein are in very presentable and readable form. It was decided by the nominat,ing committee when meeting for thc purpose of nominating officers for 1928 to eliminate the vice-chairrnanship for Transportation Engineering, as that branch of the industry seemed to come more naturally under the activities of the American Petroleum Institute. It was also decided by this committee to institute a new vice-chairmanship for Petroleum Engineering Research. Wc have had heretofore round table discussions on engineering research, but through the newly created vice-chairmanship, to which Mr. L. C. Uren was elected, we expect to have more comprehensive sessions on engineering research than heretofort.

THE present note is intended as an addition to my previous communication on the volumetric determination of manganese, read at the Roanoke meeting," it having been suggested that the circumstances under which my experiments had been conducted, were essentially different from those met with in the analysis of irons. The method used in these experiments is the same in all its details as that described in the paper referred to. I have made seven experiments in all: two of these were in duplicate on half a gramme of a sample of spiegel dissolved in hydrochloric acid; one was on the same amount of spiegel with the addition of 25 C.C. of a standard solution of potassium permanganate; one was on the same amount of spiegel with the addition of 35 C.C. permanganate and much organic matter, viz., one drop of castor-oil, two or three drops of coal-tar benzol arid of gasolene (petroleum), about ten of alcohol, portions of starch and of sugar about the size of a small pea, and about half an inch of a common match cut into shavings. This organic matter was added to the manganese solution after the hydrochloric acid had been replaced by nitric, and the solution was heated until the wood-shavings had disappeared. The fifth experiment was made by dissolving half a gramme of spiegel alone in nitric acid; the sixth by dissolving half a gramme of spiegel in nitric acid with the addition of 25 C.C. potassium permanganate, some oxalic acid, half an inch of a match, one filter-paper 7 cm. in diameter, and two drops each of castor-oil and turpentine; and the seventh experiment by dissolving half a gramme of spiegel in hydrochloric acid and adding 35 C.C. permanganate, without however taking the precaution to evaporate off all the excess of hydrochloric acid. Under these circumstances, one would expect that if organic matter exercises any influence on the determination, it would be plainly evident in the results obtained. But the accompanying table of results

Operators concerned with the destruction of their piping by acid mine waters will be interested in the method by which this problem was solved at the Cardiff mine of the Homer group. Rubber lined, or acid resisting metal pipes were found too expensive. Casting concrete lining in pipe would have required a minimum thickness of one inch, thus excessively reducing the pipe's diameter, as well as taking twenty four hours per length of pipe. The Naylor Pipe Co. of Chicago, having experimented with centrifugal lining of pipe with concrete, provided information which eventually solved the problem. An experimental plant was constructed as shown, and the following procedure developed : (1) Kerosene is used to remove the interior oil coating of new pipe. Closed with blank flanges, the pipe is revolved for eight minutes at varying speeds. Stopping and starting the motor achieves a good washing action. The kerosene is then drained off, and similar washing action with caustic soda removes any excess. Swabbing in done with burlap fastened to a 1/2-in. pipe.

Since the development of dispersion-hardenable lead-antimony alloys' in the laboratories of the Western Electric Co., Inc., studies have been made of the effect of various third constituents on these alloys.2 This paper covers a study of the effect of small amounts of arsenic. This element is important since it occurs as an impurity in many commercial antimonial leads and the results obtained are particularly interesting as indicating a class of addition agents which exert a stabilizing effect on dispersion-hardened alloys. Experimental In order to study the effect of increasing amounts of arsenic, a series of alloys were made up containing 1 per cent. antimony, and arsenic varying from 0. to 0.10 per cent., the balance Doe Run lead (99.997 per cent. lead). The alloys were cast into bars 1 1/2 in. wide by 3/4 in. thick and cold-rolled to about 1/8 in- thickness. Three samples of each composition were annealed 1 hr. at 225" C. and quenched in water. One set was aged at room temperature, one at 50" C., and the third at 100" C., the

Construction of new large refineries was small in 1937, but extensive modernization and expansion of existing plants were made, bearing out the observation of the Bureau of Mines that the trend is strongly toward fewer and larger refineries. Building the first large combination skimming and cracking unit of 20,000-bbl. capacity was a startling achievement four or five years ago, but it has been exceeded many times since, and at least four units with a capacity of 30,000 bbl. or more were contracted for during 1937, as well as many other units of smaller but still substantial capacity. Installation of polymerization plants for producing high-antiknock blending naphthas from refinery gases progressed at an accelerated rate in refineries affording sufficient raw gas to make the use of the process profitable. The total productive capacity of polymerization units built and contracted for in the United States is now about 25,000 bbl., equivalent to the gasoline production from approximately 55,000 bbl. of crude oil a day. Octane Fuels Also utilizing refinery gases—the butylene fractions in particular—the plants for manufacture of iso-octane increased in number to such an extent that the combined capacities will enable the air forces of the United States shortly to go entirely to the use of 100-octane fuel, indications being that the Army will reach that position in 1938, with the Navy not far behind. Commercial air-lines are expected to take advantage of the greater power of high-antiknock fuels to gain the increased power and increased pay loads possible with their use. Work done on producing fuels with octanes beyond the 100 point has recently been reported, and their production can be expected, although at high cost, when the economics of the situation justifies and engines capable of utilizing them efficiently are available. In the field of motor fuels, important work was reported to the A.P.I. at its annual meeting, on the effect of altitude on antiknock requirements

I. N. KNAPP, Ardmore, Pa. (written discussion*).-The possibility of storing natural gas in the sands f exhausted gas pools might be, in many cases, a, good engineering proposition, but it cannot be considered a practical business proposition tinder the usual competitive leasing and operating conditions that exist in the natural-gas business. Under the usual conditions of diversified land ownership and leasing with all lack of cooperation, various operators drill into the same pool or reservoir and drain out the gas under each other's land. To attempt to use for storage purposes the depleted sands f any one pool having such various competing ownerships would be highly impractical, considered from operating and business standpoints, unless there was cooperation with the interests owning adjacent wells and leases or the purchase f the same. Also, it would be very difficult to find out whether all old or abandoned wells in any pool had been properly, plugged and thus prevent the waste of gas brought from a distance for storage. Another objection to Mr. Panyity's proposition is the probability that no lease made in the past contemplated the use of a gas sand for storage purposes. Very likely, then, the operator would have a lawsuit on his hands for the unlawful use of a lease if he attempted the storage f such gas without first obtaining additional lease rights. In some instances salt water could not be pumped from a gas well in the customary way of pumping oil wells on account of the deposition of salt in the pump valves or in the working barrel or tubing. Very ingenious compressed air jets have been devised and arranged with suitable piping to blow out such salt-water accumulations. In many pools it would be impracticable to drill a water pocket below a gas sand, as suggested, since such deeper drilling would probably. intensify water troubles.

No exact demarcation can be made between producfion engineering and engineering research projects which interest production engineers because the results of today's engineering research make possible many of the applied production engineering methods of tomorrow. A corollary of the development of fundamental research is that so-called practical research becomes necessary. Assuming engineering research to include all subjects related to oil and gas production on which knowledge is being increased through experimentation and through analyses of data obtained from both the laboratory and the field, a review of the work of 1932 shows that the fundamental concepts of at least three major problems have become better understood—bottom-hole pressures, solubility of gas in oil, and fluid movement—and that the established data on the relationships of oil and gas have been applied to obtain more efficient and more economic production of both. Engineers no longer are concerned primarily with the initial development of devices for obtaining the pressures at the bottom of wells. Advancement in the technique of obtaining reliable pressure readings in wells has been rapid. One of the first public suggestions regarding apparatus for obtaining precise information at the bottom of oil wells was made before the Petroleum Division of the A.I.M.E. in 1928. Even during the early development stages in East Texas, reservoir pressures were estimated from well-head observations. Soon, however, a number of proved devices and methods were available, and today bottom-hole pressures in many fields are being recorded and studied as an essential part of the production programs. The research now turns to interpretations of data, obtained with these devices, in terms of reservoir energy and to the development of methods whereby the oil and gas will be withdrawn in accordance with rational and equitable programs based on oil-gas-energy relationships. The term ((bottom-hole pressures" should not be interpreted as indicating the full scope of all research on this problem. By using pressure (and temperature) data obtained in related vertical-flow studies,

Have your name and address on the first page of your manuscript. Typewritten manuscript is preferred, but is not essential. If you have the manuscript typewritten, have it double spaced and written on one side of the page only; send two copies to us if convenient; only one copy of the illustrations is desired. In typewritten manuscript, formulas are better inserted by hand. Keep a copy of your manuscript in case of loss in the mail. ILLUSTRATIONS.-Photographs reproduce best when printed on glossy paper. Solio is one of the best varieties. A good print is preferable to a negative. Blueprints, drawings, or pen or pencil sketches can be used for line engravings, but care should be exercised to make them legible and clear, especially in the case of blueprints. Tracings or photographs of drawings are preferable to blueprints. Rough sketches can be used, if necessary. Photographs should be sent flat, not rolled. Do not put reference letters or other marks on photographs; if such letters or marks are necessary, fasten a piece of tracing paper to the top edge, trace a rough outline of the picture upon it and then place all letters, etc. on the tracing paper lithe exact position you wish them to appear. Restrict the number of micrographs as much as possible on account of the considerable expense involved. Standard magnifications for non-ferrous metals and alloys are recommended as follows: 10, 25, 50, 75, 100, 150, 250, 500, 750, 1000, 1500. Micrographs should be trimmed to 2 1/4 X 2 1/4 in. (six micrographs to a plate), or, if larger, up to 3 1/2 X 4 in. (two to a plate). The smaller size should be adopted if consistent with adequate representation of the subject. With each micrograph should be attached an explanatory title, together with the actual magnification, etching medium, treatment, etc., indicating what the author intends to show.

Discussion of the paper of Frederic P. Dewey, presented at the Cleveland Meeting, October, 1912, and printed in Bulletin -No. 70, October, 1912, pp. 1075 to 1101. EDWARD KELLER, Perth Amboy, N. J. (communication to the Secretary *) :-Mr. Dewey, in his paper, offers a liberal addition of new data to those already to be found in the technical literature on this subject. However, now as before, the work issuing from the U. S. mints and assay-offices conveys the impression that systematic sampling in those institutions is more or less a secondary consideration, the chief attention being given to the principle of producing approximately homogeneous bars; recourse being taken to remelting or refining the bullion. This practice has been definitely rejected in the realm of copper-bullion sampling, for the reason that in such operations there are always unaccounted losses. Does not the same objection hold true for gold-bullions; although, perhaps,in a lesser degree ? Differences of opinion would seem justified on the following statements made by Mr. Dewey: 1. "Only two classes of alloys can form homogeneous bars-those that are solid solutions, and the eutectics."

The objective of the mission was basically to study the utilization of engineers and engineering technicians and their interrelationship in the Soviet Union. Beginning with their graduation from the engineering institutes and technicums, we hoped to learn how the graduates started out in industry, what their training on the job was, what sort of work they did, and how they worked themselves up within their profession. However, it turned out that, as our host was the Ministry of Higher and Secondary Education, most of our visits were to educational establishments. Our itinerary covered Moscow, Leningrad, Kharkov, Rostov, Baku, and Tashkent, with a side trip to Samarkand. In all, we visited 13 technical institutes, three technicums, and five industrial plants or enterprises, as they are called there. Our trip was one of only four weeks. Our observations were limited by the few cities and enterprises we were permitted to visit. Nevertheless, we did come back with some definite impressions and conclusions which we feel should be of interest to engineers, educators, and those concerned with the relative economic and technical power of the USSR and the U.S.

Pollution control will be of utmost importance in the 1970's. In this area, the mineral process engineer has a special competence to understand and remedy many pollution situations. There is an old adage that goes, "Build a better mouse- trap and the world will beat a path to your door." Would that it were so, but the reality of the situation is such that, just as a supplier must sell his machine, a professional man must sell his competence. It is a sad but true fact that mineral processing engineers have not done a very good job in selling their extensive competence in the control of a broad range of pollution problems. Recently one of our students visited a paper pulp mill where he was shown a foam fractionator used to remove paper pulp fibers from plant discharge waters. "Foam fractionator hell, that's a flotation cell!'' was his comment. Ah so, it would appear that large numbers of technical people consider themselves experts on "foam fractionation" Or is it that we have been very remiss in demonstrating the usefulness of our equipment and processes and our professional competence to solve, these pollution problems?

The Long Island Lighting Co. has operated an extensive monitoring system for over three years. Nearly 900,000 separate pieces of information have been recorded for a land area of some 600 sq miles, 15 miles north to south by 40 miles east to west. The data are composed of about a half million sulfur dioxide measurements at various locations, 290,000 of which were by the West-Gaeke method, about 160,000 pieces of weather data, and 220,000 measurements of sulfur dioxide as emitted from each of the power plant stacks on the system, all measured on an hourly basis and stored on computor cards and tapes. The computor has been programmed to collate stack emissions, weather information, and ground level sulfur dioxide measurements. The analysis shows that emissions from tall stacks do, indeed, contribute very little to ground level sulfur dioxide. For example, LILCO shows that its Northport plant contributes less than 2 ppb, hourly annual average. They also state that the plant converted to 100% natural gas or shut down, would reduce ground level sulfur dioxide by no more than 2 ppb.

THE equilibrium y phase in Cu-Be alloys forms by discontinuous precipitation, the new phase nucleating at the grain boundaries and growing into grains on both sides of the boundary. When the alloy is aged above 500°C, however, growth may take place into only one of the grains.1'2 In A1-Ag alloys it is known that the precipitate has the same orientation as the grain in which no growth takes place.3, 4 This was confirmed in the present investigation on a Cu-Be alloy. A Cu-1.79 wt pct Be alloy was solution-treated at 810°C for 2+ hr, quenched into water at O°C, and aged at 600°C for 1 hr in a salt bath. The specimen was thinned by chemical polishing and electropolishing at room temperature in a solution of H3PO4 saturated with CrOs. The foil produced was examined in a JEM 150 electron microscope operating at 150 kv. Fig. 1 shows precipitates growing on only one side of the grain boundary. The black platelike precipitates were identified as the y phase. Electron dif-

MICROCRACKS are often introduced into commercial metals during fabrication processes such as swaging, cold rolling, deep drawing, and welding. These microcracks act as strain concentrators and may be capable of causing premature catastrophic failure of a component or weld. The present investigation was undertaken to determine whether high-temperature annealing treatments may be capable of reducing or negating the detrimental effects of such existing microcracks. Internal microcracks, ranging from 0.1 to 0.85 mm in length and averaging 0.23 mm, were introduced into polycrystalline Fe-3 pct Si tensile specimens (0.155 mm grain size) by the cathodic charging of hydrogen.1'2 The typical appearance of such microcracks and their associated strain patterns (made visible by the technique of dislocation etch pitting3) is shown in Fig. 1. The stress fields of the dislocation loops formed during plastic relaxation stabilize the microcracks so that, when the internal hydrogen pressure is removed: the microcracks stay open, rather than disappear as perfectly elastic cracks would be expected to do.' As shown in Fig. 2, such stopped microcracks cause a 36 pct decrease in the macroscopic cleavage fracture strength at -196°C.

. S. W. PARR, * Urbana, Ill. (written discussion ? ).-Multiplication of argument is unnecessary to establish the desirability of coking coals at low temperatures, that is to say, below 1200° F. The value of the semi-coke thus produced would doubtless go far toward solving the problem of smoke prevention, and suggests the possibility of the substitution of a smokeless fuel for anthracite and so-called smokeless coals. Whether such coke would have any value as metallurgical coke is a question which cannot be answered for lack of any experimental data in the use of such material. Of course interest is accentuated, at the present time, in the amount and character of the tars, which promise greatly to exceed in values the products obtainable from. the high-temperature process. The difficulties encountered in adapting the principles of low-temperature carbonization to industrial methods are well nigh insurmountable. Briefly stated, there is involved the heating of the center of a mass of non-conducting material by the external application of heat. It is a well established fact that the center of the mass of coal in a standard
