A SERIES of awards for men and women in indus-try who by their inventions, heroisms, vision, and powers of mediation are contributing daily to the life and well-being of America in a substantial way, will be given by the Harmon Foundation. The series, to be known as "Awards to Honor Men in Industry," consists of two cash prizes, $1,000 and $500 each, accompanied by a gold and silver medal respectively, and 100 bronze medals. No one above the rank of foreman will be eligible. Because of the diversity of .American indus-try, the Foundation is planning to confine its awards during the first year to the following branches of man-ufacturing: automotive, building, electrical, metal and textiles, including clothing. The Harmon Foundation invites the general public, newspapers, organizations and employees to bring to its attention such persons as they may deem worthy of the award.

At the meeting of the Institute, held at Roanoke, Va., in June, 1883, I gave some facts in relation to charcoal pig iron of unusual strength, made from our carbonate ore taken from the mine at Amenia, N. Y. My object in again bringing the subject to the attention of the Institute, is to obtain, if possible, the solution of a prohlem in connection therewith. Our furnace is of the old type, stone stack 32 feet high by 9 feet 2 inches at top of bosh; bosh about 67O pitch; stone hearth; three tuyeres of 31/4-inch opening; fuel, a mixture of hard and soft coal; blast about & to # pound pressure, and heated to 400' to 600° Fahr. by iron pipe oven on top of stack. The analysis of the roasted carbonate ore, as before given to the Institute, is as follows:

Alan Stanley (Titanium Dioxide Analysis of Maclntyre Ore by Specific Gravity, P. 971) is currently head of the General Metallurgical Group of the National Lead Co. He has been with National Lead since 1946, after serving with the USAAF as a first lieutenant of engineers during World War II. A native New Yorker, he graduated from Virginia Polytechnic Institute in 1942 with a Bachelor of Science in Chemical Engineering. Since joining National Lead he has been a flotation supervisor, in the high tension pilot plant, and done sinter testing. He is an AIME member and presented one other paper before the Institute, Sintering Characteristics of Minus 65 and 20 Mesh Magnetite. Stanley plays the piano in his leisure moments.

WHEN a wire rod of iron or of steel is immersed in a hot. solution of common salt, allowed to remain long enough to bring the metal to the temperature of the brine, and withdrawn, the surface of the rod is irregularly covered with a deposit of crystals of salt. These crystals adhere to the cod with great firmness, in consequence, doubtless, of a thin film of ferric hydrate, which is formed between them and the rod as the water dries tiff. The rod can now be re¬duced, by successive passes through a dic or draw-plate, without any

IT has been reported that both berylliumL and zirconium&apos; developed the same basic textures during rolling at temperatures up to 1475 °F as at room temperature, differing only by an increase in the spread of basal planes toward the transverse direction as the temperature of deformation was increased. Iodide titanium&apos;&apos; rolled at 1050°F has a texture similar to the cold-rolled texture, {000l}, 25° to 30" from the rolling plane toward the transverse direction, <1010>, Rolling iodide titanium at 1450°F produced a more random condition with the basal planes parallel to the rolling plane and no direction strongly aligned with the rolling direction.

H. L. Burghoff.*—I have a question, Dr. Smith. A number of the alloys you mentioned contain lead, which, of course, is present as discrcte particles. At what level of concentration does lead begin to play an important part in determining these elevated-temperature characteristics ? A. J. Smith.—That is a difficult question to answer because of the complicating features of the alloys that arc lead free. I do not know of any work done on the subject. But for comparison, 85-5-5-5 has about the same characteristics at, say 450°F. as 88-10-2, which is lead free or contains at most 0.30 per cent. Both 85-5-5-5 and 88-10-2 precipitate delta. The specification limit of usage is 406°F., temperature of saturated steam at

The solid inclusion cell for absolute in situ stress measurement has been found to give reliable results in coal. The cell is described briefly, along with the methods of installing, overcoring and taking readings in underground coal mines. The validity of the cell performance is demonstrated by reference to the stress-relief curves obtained during overcoring and a three-dimensional B.I.E.M. analysis of the installation to test for stress anomalies deriving from the geometry of the overcoring groove-borehole-cell arrangement. Case studies of two stress measurement projects using the cell are presented for coal mines in New South Wales, Australia.

In 1964, mining education in the United States will celebrate a 100th anniversary-that of the founding of our first school of mines at Columbia University. Prior to that, curricula leading to degrees in mining and metallurgical engineering were offered in 1853 by the Polytechnic College of Pennsylvania in Philadelphia. But the New World&apos;s earliest achievements in mining and metallurgical education were those of the Spanish in what is now Mexico. American metallurgy probably goes back to Father Jose de Acosta, who in 1590 described the metallurgy of silver and mercury in the New World.&apos; The Spanish priest and metallurgist Don Alvaro Alonso Barba Toscano (1569-1662), in his hook The Art of Metals, published in 1640, stated a need for a school of mining and metallurgical education in the New World. (The latest translation of this book was made by R. E. Douglas and E. P. Mathewson and published by J. Wiley & Sons, New York, in 1923.)

The University of Illinois, by Prof. H. H. Stock, professor of mining engineering, sent out to its mining students a long letter urging them to attend a Chicago meeting of the Institute. It stated that the University Council authorized the remission of the registration fee for sophomore, junior and senior mining engineers who would attend the meetings and present a written account of the sessions and excursions attended. Young engineers are rarely flushed at the beginning of their careers but if they ever expect to amount to anything at the end of 10-years-they are going to regret that they have not long been a member of the Insti-tute. So that the slogan "Do it now" is snore than particularly appli-cable in their cases and nothing will better indicate to them the scope of the Institute&apos;s work and the advantages which they are to get from mem-bership than attendance at one of the big meetings of the Institute and the preparation of a written report on the sessions and excursions attended to be returned to the University.

In aqueous solution, an oxide surface is considered to consist of positively charged surface sites, MOH, neutral surface sites MOH, and negatively charged surface sites MO-. From the mass action law, equations for the distribution of these sites have been derived in terms of the hydrogen ion concentration in solution and the point of zero charge of the oxide. Experiments on the flotation of futile were carried out with sulfonates and amines which are collectors that physisorb, and with oleate, which is a collector that chemisorbs. Flotation response was found to correlate with the site distribution model. A similar correlation was found with published data on iron oxide potation.

Fracture tests were conducted on subsize specimens of Charcoal granite to demonstrate that the extent of the nonlinear region at the crack tip can be significant. The model of the fracture process considers an effective crack length as a traction free portion plus a process zone where closing stresses act; this zone is identified by microcracking and interlocking. A singularity is allowed at the effective crack tip. The effective stress intensity factor is the superposition of the stress intensities due to the effective crack and the process zone. By assuming that the closing stress is a linear function, it is shown that a process zone length of approximately one-third the effective crack is needed to match the compliance-determined crack length.

The discovery of oil in the Powder Wash stricture in northwestern Colorado late in the fall of 1936 is the most important development in Colorado since oil was first discovered in the Moffat dome in the same county in 1923. The Powder Wash structure gives promise of developing into an oil and gas field of major proportions and is of particular interest because the oil was found in Tertiary rocks of Eocene age, which heretofore had been productive in the Rocky Mountain region of gas only, and very few of the many structures of this kind have been tested because it was believed that oil production probably would be confined to rocks of Cretaceous age only, and these were, in most instances, at excessive drilling depths. Powder Wash is one of a series of small domes in the belt of folds and faults on the south side of the large but shallow depression known as

Some months ago I heard from a party of returned tourists an amusing story of a Chinese laundryman in the National Park who had included in his cabin a hot spring, of which he was accustomed to avail himself in his business, and who, on one occasion, having thrown a lot of linen into this spring to soak overnight, had added a piece of soap to facilitate the process, and had been considerably surprised when, stimulated by this soap, the spring had suddenly become a geyser and wrecked his establishment. The story went on to say that the practice of "soaping" geysers to make them, active had become general, but had been forbidden by the authorities.

Albert Ludwig Serlo was born February 14, 1824, at Crossen-on-the-Oder. After completing his school-studies and his training as a mining official, he received in 1851 an appointment as Royal Manager of salt-works (Salinenfactor) and member of the Administratioll of Salines at Konigsborn, near Unna, Westphalia. The issue of new regulations for the training of higher State officials in the Department of Mining, Metallurgy and Salines, led him to pass in 1856 a special examination for the rank of Assessor, in consequence of which he was called to Berlin, to serve for a few months as an assistant in the Ministry of Commerce, which had charge of mining, etc. In the same year he became Bergmeister and member of the mining administration at Bochum, Westphalia, and in 1858 Oberbergrath and member of the provincial administration, called the Oberbergamt, having its headquarters located at Dortmund. In 1861 he was appointed Director and head of the newly-reorganized mining

For the producer of industrial rocks and minerals, marketing is often the only means of survival. His material must be sold. There is little of the impersonal force of the market regulating supply and demand. No commodity exchanges facilitate his efforts to dispose of the material he produces, and the success or failure of his business depends primarily on prompt and correct response to market needs and requirements. This response is particularly vital where materials of low unit value must be shipped to distant consumers owing to a relative rarity of suitable deposits. The advantage of positive response to change can best be illustrated by hypothetical cases showing how problems can be turned into opportunity through marketing ingenuity. Three such cases dealing with materials of unit values in the range of $5 to $100 per ton are outlined below.

Many of the proposed techniques for calculating the reliability of rock slopes utilize Monte Carlo simulation. Monte Carlo approaches are attractive because they provide means of solving probabilistic problems with deterministic algorithms. One disadvantage shared by all simulation-based stability analyses is that they assume all the random variables are independently distributed. The paper focuses on the independence assumption and examines the effect of correlation on the probability of failure. In particular it considers the influence of possible (albeit hypothetical) correlation between joint attitudes [(8)] and joint friction angles [($)]. The study indicates that neglecting correlation can introduce significant errors into the reliability computations. With a modest positive correlation between [8] and [$] the error can lead to a 100% overestimate of the probability of failure.

Can the mining industry in the United States accept the change and challenge of the "Now Generation" of an entirely new high-performance automated transportation system? Advanced transportation systems for the mining industry can be defined as those which lend themselves to automation and meet definite performance and cost objectives. The term automation shall mean that control of transportation system is accomplished by a closed loop electronic circuit which, when started on command, will continue to cycle as programmed until such time as an intelligent feed-back causes the system to shut down.

In the technical literature of 1965 and 1966, there were several papers about future power for mining and construction equipment. Most of these papers made the same predictions: •More power •Better reliability and durability •Ease of service and maintenance •Operating economy •The possibility of future environmental concern •The entrance of the gas turbine In the five years that have since passed, some of the 1965-66 predictions have at least partially come true, while others have not been fully realized. Actually the list still appears sound today. Priorities may have changed and details may be different, but the main points cover the requirements for future prime movers quite well.
