We have not yet begun. to realize the possibilities of automatic machinery, in part because we have not developed the designing brains, and in part because we have not sufficiently simplified industry to make possible the economical use of such machinery. The principle of the Jacquard loom, has scarcely been utilized except in weaving silk and in the player piano. It is the principle of bringing into action the various parts of a machine in accordance with a pattern traced on a steel card by perforations or as on the paper roll of a player piano. This principle gives us a control which can be applied to any kind of machine. It is a' great reserve principle for the future. But even now, with the machinery that we have at command, anyone can cut the number of employees in two, at the same time doubling his output, by installing semi-automatic or automatic machinery. And no one knows how far this process can go on. Cutting down the number of men is not just putting some poor fellows out of a job. It is increasing the number of good jobs by increasing the production per capita to a point where really satisfactory wages can be paid out of it, and this in turn- increases the amount of work required to be done and creates new jobs. Thus, cheapening in- creases the demand.

THE problem of maintaining the mining industry is two-fold; finding new supplies in the face of increasing difficulties, and making such advances in the arts of extraction and preparation as to use supplies of lower grade. Progress in mining and reduction methods and in transportation makes ore today of that which was waste yesterday. These are the fields of the metallurgists and the transportation engineers. The geologists and mining engineers must work together on the problem of ore finding. As the old prospector fades from the scene, men with equal hardihood and patience and equal power to meet the physical obstacles which confront the seeker after ore, must take his place, armed with all that has been learned from human experience about the causes, the controlling conditions, the indications, and hiding places of the metals. Such a seeker is dealing with some of the most complex and obscure of natural phenomena. In nature's laboratory, tremendous forces are at work. Tempera-

THERE are two methods employed in the development of oil pools. The older and dominant method is one in which the primary object is the protection of the underground deposit from drainage through competing wells, and considerations of efficiency of extraction and cost of production are subordinated thereto. The newer and less prevalent method is one in which maximum efficiency and minimum cost are the first objectives and developments to these ends may proceed undisturbed by the exigencies of competitive drainage. The second method has developed mainly in pools under single ownership and the term "unit operation" has come to be applied to this procedure. A single ownership, however, is not essential to the method, for unity of operation may be achieved by agreement under split ownership, or even by a concert of enlightened purpose. There are examples of unit operation where neither the ownership nor the management is a unit, but merely where unity of procedure has been attained, as is the case of the Yates pool. .Throughout this paper unit operation is used in its broad sense without implying sole ownership or single management, although unit operation is more conveniently attained where these conditions are present.

THE Iron and Steel Division and the Institute of Metals Division are laying plans for a rousing meeting the week beginning Sept. 21 in the land of the bean and the cod-at Boston. The two divisions are collaborating with the American Welding Society, the American Society for Steel Treating, and the Iron and Steel Division of the A. S. M. E., to have technical sessions of widespread interest and social affairs that will compare with the best of previous years. In connection with the meetings an exhibition of production and testing equipment, heat-treating equipment, furnaces, welding equipment, and metal products will be held on Commonwealth Pier all week, where those attending may see the latest developments in the field of their own work.

IT IS particularly appropriate that a paper on this subject should be presented in Spanish, before a Spanish speaking audience, and in a South American country, first because of the facts that these countries today have not only the largest copper leaching plant in existence but also present great opportunities for future extension of hydrometallurgy; and second, because of the fact that the first copper made by any wet method was doubtless produced before existing records at the Rio Tinto deposits in present day Spain.

ENGINEERING COUNCIL has passed, not out, but upward! Therefore, its recent wake was conducted by itself as a joyful occasion somewhat in advance of its official demise. Council held its last meeting in Washington, Dec. 16, 1920. Business was transacted with dignified gravity in the forenoon. During the afternoon calls were made upon the chiefs of technical bureaus of the Government: the Chief of Engineers, U. S. Army; Chief of Yards and Docks of the Navy Department; Director of U. S. Reclamation Service; Director of U. S. Geological Survey; Director of Bureau of Mines. The Council pronounced them, each and all, able men and true. But what of the evening? Well, there was a dinner at the Washington Hotel. Twenty-six men gathered around a flower-strewn table-not a casket. As guests, there graced the festive board the hosts of the afternoon calls, and a number of members of the new American Engineering Council. The body about to be apotheosized-otherwise known as Engineering Council-was both jocular and reminiscent. Rewards were bestowed and appreciations expressed. To the man who had for three long years borne the burden of chairmanship and whose financial recklessness made possible the Washington office and the movement for a National Public Works Department, the following "note," duly engrossed and signed, was given, accompanied by "The Song of the Council Crew."

REPUBLIC STEEL'S new iron blast furnace in Alabama, shown on the cover of this issue, is the first to be completed of those authorized by the Government last year when a shortage of scrap became acute. In addition to the furnace, the new equipment includes a new battery of by-product coke ovens, a boiler plant, a generating unit, a 3-mile-long 60-in. water line, a huge gas washer, and precipitators in which the dust from the furnace is washed, separated from the water, and fed back into the furnace as raw material. The new unit is a cylindrical steel giant reaching 130 ft. into the air above the ground level. Because of the high humidity in the deep South, the furnace has been air-conditioned to avoid blowing eighteen tons of water into the furnace daily. Designed by Republic engineers who also had charge of the actual construction, the new furnace incorporates the best in modern blastfurnace practice. Orders to proceed with the construction of the furnace were received Sept. 22, 1941. The engineering crew, which was immediately organized, made more than 1500 drawings. Excavation started the next day, and simultaneously work was begun on demolishing existing buildings and preparing the site. The first concrete was poured Oct. 7 and the first piece of steel swung into place by a giant derrick on Jan. 30, 1942. It began operating May 28. A total of 70,000 cu. yd. of earth was moved and 30,000 cu. yd. of concrete poured.

THE better control of production was made the topic for a special program of the annual meeting of the Institute last February. In the discussion at that meeting it was brought out that in many branches of the mineral industry (as in other industries), there was faulty industrial coordination. Those who were best informed by reason of their intimate connection with coal, copper, oil, iron, lead and zinc, and almost all other of the essential minerals pointed to a condition of chronic over-capacity, to the dissipating use of irreplaceable minerals, to an unstabilized price structure, and to over-stimulatecl production and the destruction of some mineral resources over and above what is thought to be the needs of prudent cur- rent consumption. The discussion went far enough to point out the existence of various problems, and the question then raised was "what can be done by way of self-coordination of industry?" by "production control from within?" or in other words, "how can the mineral industry protect its resources against waste and at the same time protect both the producer and consumer against loss from prices that are too low or too high?"

THE material available for mineralogic study, consisted of drill cores, 2 to 3 in. thick, supplemented by small well cuttings. Such study has added no essential new information regarding the minerals, though the refractive indices, used for determinative purposes, have been determined more accurately than before, permitting the development of a scheme for the rapid identification of these minerals. The essential points brought out by the investigation are two: (1) that certain mineral associations evidently point the way to an understanding of the geologic history and (2) that a definite sequence of mineral formation has taken place so that the original minerals formed have been in part-reacted on producing new compounds and associations; Twenty minerals have been found. The most important are :

SERIOUS consideration was given by the Petroleum Division to a wide variety of subjects, during six busy sessions at the Annual Meeting. Beginning with a joint session on engineering research and production engineering, Tuesday afternoon, conducted by E. A. Stephenson and H. C. Fowler, problems of petroleum technology, domestic and foreign production, proved oil re- serves, economics, and stabilization were mooied almost without interruption until nearly everyone was "talked out,' and the meeting was adjourned at the end of the annual Petroleum Division dinner, late Thursday night.

SIR HENRY CORT HAROLD CARPENTER, great-great-grandson of Henry Cort, famous as the initiator of iron puddling some 150 years ago, carries on the tradition of an illustrious name. Newest of those elected to the Institute's roster of Honorary Members, Sir Harold is distinguished for his achievements in the field of metallurgy as an investigator, teacher, administrator, organizer, and director of research. His interests in research have been in both the ferrous and non-ferrous fields. His name is particularly honored in its association with the establishment of fundamental con¬stants and of critical ranges of iron and iron alloys, and with original and fundamental studies of the preparation and properties of metal single crystals.

THERE is a need for men well trained in geo- physical prospecting. Although the number of geophysicists required by the industry in the future cannot be expected to be very great, there will always be a demand for courses on the subject. A number of educational institutions are, therefore, interested in providing instruction in geophysical prospecting. Some institutions will be satisfied with courses in general geophysical prospecting designed to give the geologist fundamental concepts on the comparative merits of the methods and the interpretation of the results. Other institutions will want to give special instructions in theory, field procedure, and interpretation of any or all geophysical methods. In giving such special courses a number of problems will be faced, and it seems to me that such difficulties are easier to overcome in an engineering institution than in a university. A knowledge of basic engineering subjects, such as required of all students in an engineering school, seems to be the best foundation upon

IT is assumed that the word "college" for the present purpose signifies technical school or technical department of a college or university. About ten or fifteen years ago, and more recently in some instances the contact between the technical school and the industry, as represented by the operating companies, was very limited. The school made no effort to place its graduates in the industry and the graduate's first position was obtained by his own or his friends' efforts; the friend often was a professor. The industries, or the operating companies, seemingly had little interest in the training of the technical graduates they employed or in seeking to discover their personal characteristics and fitness for the work. In the public mind there was little relation between technical training and industry. Such training was in the field of education; industry was in the field of business; and the interrelationship was not a matter of common knowledge or concern.

T HE smelting industry in Utah is represented by four plants: The Midvale of the United States Smelting, Refining & Mini.ng Co., the Murray of the American Smelting and Refining Co., the Garfield of the same company and the Tooele of the Inter- na.tiona1 Smelting Co. The first two are lead smelters, the Garfield plant is a copper smelter while the last named embraces both a lead and copper smelter. A total daily smelting capacity of over 10,000 tons is represented, of which 4000 tons is lead smelting capacity. With the exception of Tooele, forty miles distant, all of these smelters are within twenty miles of Salt Lake City. Pyrometallurgical operations in this district are con- fined entirely to the production of unrefined bullion, which is shipped east to the various refineries of the respective companies. The smelting industry in this state had its beginning away back in the latter days of the Civil War, many years before the completion of the trans-continental railroad. Ox teams were still bringing their companies of better fixed Mormon emigrants across the plains to the valley of the Great Salt Lake and those in lesser circumstances were still pushing their hand- carts over the same roads to the temporary abode

THE great work of Gorgas in stamping out yellow fever in Panama during the construction of the Canal was one of the chief factors contributing to the ultimate accomplishment of the task, two previous attempts having failed largely through the demoralization of workers by epidemics of contagious diseases. Mining camps, rapidly constructed during the boom days of the rushes to new fields, have been frequent sufferers from typhoid when, as so often used to be the case, little or no attention was given to bacterial examination of the water supply or to the method used for disposing of the sewage.

THE-Institute of Metals Division opened on Tuesday afternoon with Wheeler P. Davey as chairman and G. E. Edmunds as vice-chairman. Four papers were on the program, two being of a fundamental character. A paper on "Internal Surface in Minerals and Metals," by R. S. Dean and J. Roster, was presented by the latter; C. H. Gottschalk discussed coercive forces in powders. In answer to a question by the chairman. The author stated that he had not investigated [he temperature coefficient of resistance. A paper on "Recrystallization and Grain Growth in Cold Worked Polycrystalline Metals," by L. W. Eastwood, Arthur E. Bousu, 'and C. T. Eddy, was presented by Mr. Eastwood. A. great many quantitative data were given, with little reference to the theory. Theoretical considerations were discussed by Dr. Gottschalk, and C. A. Edwards of the University College of Wales, contributed very interesting comment on the relationship of size and critical strain. Dr. Edwards discussed the necessity of considering strain with time and temperature.

THE time of the Section delegates was economized this year by providing the section reports in mimeo- graphed form, together with the reports of the officers and committees of the Institute, for their consideration on arrival. The meeting was called for Thursday forenoon and despite a certain amount of oratory managed to get through before all the luncheon was gone. In all, nine section delegates and one from the Iron and Steel Division attended and took part. One delegate, who had come many miles, got lost in the complication of the program and failed to attend. Six appointed dele- gates failed to attend and two sections neglected to make appointments.
