The regular activities of the Institute are financed mainly by income derived from members' dues, from advertising in MINING AND METALLURGY, and from the sale of publications to the public. In addition, collateral activities and special projects are financed each year by means of income from endowed funds controlled and administered by the Institute. In the aggregate, the principal sums of these endowments amount to more than $530,000. An active effort is being made to in¬crease the endowment funds of the Institute through a standing committee, of which H. T. Hamilton is chairman, and of which the other members are: W. H. Aldridge, George D. Barron, Cleveland E. Dodge, D. C. Jackling, Henry Krumb and J. V. W. Reynders. This committee feels that there exists a tremendous opportunity for the Institute to be of ever-growing service to the public, to the mineral industries, and to the profession. It welcomes suggestions as to names of men of means who are vitally interested in the mineral industries, and to whom the opportunity to make a contribution or bequest might appeal favorably if presented in the proper light by the committee.

WHEN the need for war work was ended, the late Mrs. Sidney J. Jennings felt that the members of the Woman's Auxiliary, who had worked together so successfully, would profit by having a common permanent aim through scholarship work, financed by annual contributions from the Sections. Under her leadership the Sections responded generously and the educational fund was started. Mrs. Jennings became the first chairman of the executive committee and so remained until her death. It was planned to begin with an award of $500 each year, and to pot aside 25 per cent of all moneys re¬ceived from the Sections to establish an endowed fund. In 1921 the first scholarship of a value of $500 per annum was granted, and an award of the same value has been made regularly every year since. It is called the Subscription Scholarship. The 25 per cent, which is set aside each year and carefully invested, is called the Engineering Education Endowment Fund. Three years ago this fund began to yield around $300 annually and this income has been used each year since to finance a scholarship under that name.

The potash mine of the International Minerals and Chemical Corp. is about 18 miles east of Carlsbad, New Mexico, in sec 1 and 12, T 22 S, R 29 E, N.M.P.M. Potash is produced from two zones in the Salado formation of late Permian age. The lower zone, consisting of a mixture of sylvite (KCl) and halite (NaCl), lies at a depth of about 900 ft, and the upper zone, in which the principal potassium mineral is langbeinite (K2S04.2MgS0d), lies at a depth of about 800 ft. Because of the plastic nature of the material, fractures in the Salado formation are extremely rare and have been noted only on the 800 ft level of the International mine. The open fracture described below is almost unique. Only one other open fracture has been noted, and it was on a working face in the same general area as the one described, but was destroyed before the writer had a chance to examine it. According to J. E. Tong, foreman on the 800 level, this fracture was similar to, but smaller than, the one herein described.

In connection with the paper of Mr. Locke on Gilsonite or Uintahite (Trans., xvi., 162) read at the Salt Lake session of the Utah and Montana meeting, in July, 1887, the following data may be of interest and value. In December, 1887, I received from Mr. William Wagner, Seeretary of the Denver & Rio Grande Railway Co., a box of specimens of an asphaltic mineral from Utah. In the course of the correspondence which followed, I learned that the box had been forwarded by Mr. J. A. McMurtrie, of the firm of McMurtrie & Streeter, railroad contractors, Denver, Col. Mr. McMurtrie was, in 1883, chief engineer of the Denver $ Rio Grande Railway, and the mineral mas first brought to his attention in that year by Mr. Thomas H. Wigglesworth, who was then employed in making preliminary reconnaissances for wagon-roads to be used in constructing the Utah extension (now the Denver, Rio Grande $ Western) of the railway. Mr. Wigglesworth, I understand, was subsequently chief engineer of the Colorado & Utah Midland, and is now again employed by the Rio Grande. He writes substantially as follows concerning this mineral:

ASIDE from the John Fritz Medal, in which the Institute participates through its representation on the John Fritz Medal Board, the Institute itself has four awards it may make annually, as fol¬lows: the Robert W. Hunt Medal and Prize, the J. E. Johnson, Jr., Award, the James Douglas Medal, and the William Lawrence Saun¬ders Medal. ROBERT W. HUNT MEDAL AND PRIZE The partners of Robert W. Hunt established a fund which was presented to the Institute at a fitting ceremony on May 27, 1920, to establish an annual medal and a sum of money to be awarded under the following rules 1. The award shall consist of two prizes: first of a gold medal, second of a sum of money; a certificate to accompany each prize. The money prize shall not be awarded to a member over 40 years of age, but under unusual circum¬stances, both prizes may be allotted to one person provided that he is not over 40 years of age. In general it will be understood that the Committee shall award the money- prize to the younger men, rather than the medal.

The Wheeler Condenser & Engineering Co., of Carteret, N. J., is now building a line of horizontal and vertical shaft centrifugal pumps for general services, as well as for condenser work.. This company has been building centrifugal pumps for over 20 years, most of them being used, however, in connection with condensers. The new line of pumps is suited for all services. A small motor-driven unit for tank or stand pipe operation is shown in Fig. 1. Referring to the sectional illustration (Fig. 2), it will be seen that this pump conforms to the most recent advances in centrifugal pump construction, having a two-part divided casing, with the suction and discharge nozzles in the lower half. The impeller is of the closed double-suction type, protected by labyrinth wearing rings. The shaft is protected from the water by bronze sleeves, which screw on to the shaft and extend clear through into the bearing bracket boxes. Bearings are of the ring-oiled type, and in the outboard bracket, is a ring-oiled thrust bearing, which is a refinement not usually found in double-suction

J. A. Mathews,* Syracuse, N. Y. (written discussion?).-It is interesting to note how frequently we hear of some process that is going to revolutionize the tool-steel business. I don't know why it is, but every one seems to have it in for us poor tool-steel men. About 15 years ago, a good-sized plant was built in Syracuse for the manufacture of cast tools of malleable iron. The promoter of the scheme claimed to have a secret, process that had been given to him by a tramp to whom he gave a lift along a dusty road. The widows and orphans invested liberally in the securities of the company without consulting the men established in the machine-tool business in Syracuse. About two years later, when the sheriff's sale occurred, the secret, which was carried on the books of the company as an asset valued at $2,000,000, brought $15 at auction. A little later another concern started on the theory of replacing scrap high-speed steel with new high-speed steel tools made therefrom. All the tool-steel companies have made a practice of purchasing high-speed

TRACKLESS equipment is being used by the Coplay Cement Manufacturing Co. to develop a folded limestone deposit economically and safely with inexperienced men. Cost and quality of development stone results in a saving when it is used in- stead of outside sources of limestone. This favorable cost has been attained by following a methods development and training program described in this paper. It is expected that further savings in favor of the mined stone will be made when stopes now being prepared are in production. The present equipment will be used for loading from stope draw points. The limestone is blended with quarried cement rock to serve as raw material for Portland cement, first produced in this country by Coplay Cement Manufacturing Co. from a process developed by its president, David 0. Saylor, in 1873. For many years the cement rock alone or with a small amount of added limestone was used for raw materials. Later as specifications were raised and the richer portions of quarries were depleted, limestone from outside sources was required in increasing amounts. In 1925 D. J. Uhle, the general manager, began to prospect company property for limestone.

Most of US, in this hurrying age, take little pains to preserve such records of our doings as will make the work of' our biographers easy. Now and then there is an exception, and Dr. Trippel was one. Methodical in all his habits, he kept diaries and journals comprising his own personal experiences, the details and results of his numerous scientific investigations, and his impressions concerning men and events; and also copies of all his technical essays, published by various societies or periodicals. It is a striking instance of " the irony of fate," that these carefully-preserved materials, which would now have a real historical, as well as biographical value, were totally destroyed by an accidental fire a few years ago. In addition to my own recollections of an acquaintance covering more than thirty years, I am indebted, for the fads upon which this sketch is based, chiefly to Mr. Engene J. Trippel, a son of the deceased, and now Register of the United States Land Office at Tucson, Arizona. Mr. Trippel, however, frankly confesses that his own knowledge of his father's work is, in the absence of written records, imperfect.

Manufacture of lightweight concrete aggregate from common shale is one of the most rapidly growing industries in the field of nonmetallic or industrial minerals. Although expanded shale" has been in use since it was developed by Stephen J. Hayde in 1917, it was not until after World War II that it became a substantial competitor with other aggregates. There are some 70 plants now producing this aggregate in the United States, approximately half of them in states west of the Mississippi River. Expanding plants throughout the U. S. are grouped around major urban centers such as Los Angeles, New York, Chicago, and Denver. Concrete made with expanded shale aggregate combines the desirable features of low weight with relatively high strength, making it especially useful in concrete block, in structural concrete for multi-story buildings and in a variety of specialized concrete products such as prestressed panels and beams, and storage tanks. As the cost of construction continues to rise, lightweight concrete will probably be used in increasing quantities because of its low cost relative to the more traditional construction materials such as wood, brick and steel

W. P. PUTNAM,. Detroit, Mich.-There is one company that is heating these tubes in an upright position by passing electrical energy directly through the tube itself. The lower connection is attached to an indicator, which shows the point at which the steel passes through the critical range At that point the clamps are released and the tube is dropped into a well of oil. This method simplifies the heat treatment of tubes in long lengths. H. J. FRENCH.-I am not entirely familiar with. the method outlined, but it appears to have one serious disadvantage; that is, the length of tubing that is directly connected with the electrical contacts is wasted and must be cut off due to either heavy oxidation or burning. That is a serious difficulty, if true in all cases, and cannot be overcome, inas-much as it is very difficult to draw long tubes of thin wall. Having once obtained a lot of tubes, to cut, say 14 ft. in length, there is often little excess metal available to discard. Am I correct concerning the burning or heavy oxidation of the metal where it comes in contact with the tube.

AFTER the first session which Secretary Marshall had with the Foreign Relations Committee, the members of the press asked what he had said His only comment, in summarizing his two-hour conference was, "The world is in a very critical condition " Undoubtedly he had many different aspects of the world in mind, but I wish to underline today the truth of the statement with reference to the economic field V-E day was 22 months ago, V-J day was 19 months ago The hoped-for world of peace and plenty gives signs of attaining the peace, but the plenty seems tragically remote For great areas in the world, the present level of economic activity is very, very low Men are not working, goods are not being produced, whole areas of activity suffer from economic paralysis We in this country do not fully appreciate the situation because the United States is above prewar levels in economic activity We are the exception The same cannot be said for the world in general There are still large areas where industrial activity is not more than half the prewar level

At a meeting of the Associated Engineers, with Columbia Section in charge, a discussion of the metric system was led by-Mr. F. A. Ross. While the majority of the engineers present favored resolutions seeking compulsory adoption and use of the system at the end of 1924 it was believed the engineers present should not undertake to speak for the entire membership and upon suggestion of Mr. J. B. Fisken the resolutions were laid over to be acted upon at a later meeting. The resolutions are as follows: WHEREAS the Great War has drawn the United States into a permanent and close relationship with the other nations of the world and opened the way to an unlimited foreign trade; and WHEREAS more than-70 per cent. of all nations have discarded their arbitrary standards of weights and measures and have made the use of the decimal, or metric, system obligatory; and WHEREAS the United States still clings to an antiquated, complex, cumbersome, and wholly illogical system of weights and measures, consisting of a duodecimal and fractional arrangement of arbitrary units, instead of definitely determined and correlated units following the decimal system; and

The Minerals Beneficiation Division meets each year at the Annual Meeting of AIME. All members are invited and encouraged to attend. For the information of those who did not attend the meeting in Denver last February, this column presents a summary of the reports given and topics discussed. Technical Committee Coordination Consolidation of technical programs having common interest to MBD and the Extractive Metallurgy Division is proving a considerable success, both on the technical committee level-through the efforts of the MBD-EMD Coordinating Committee-and in special symposia. MBD Chairman, R. S. Shoemaker, noted that J. D. Prater will be serving as Chairman of both the MBD Chemical Processing Committee and the EMD Hydrometallurgy Committee for 1970-71. R. P. Ehrlich commented on the cooperative effort of both divisions in organizing the Copper Metallurgy Symposium held at the Denver Meeting. This effort, he said, was important to the success of the Symposium. H. R. Spedden discussed inter-Division coordination activities on the SME level. The forthcoming MBD-M&E-EMD Joint Lead-Zinc Symposium is yet another example of progress in this direction.
