The sixty-fifth Congress created a commission on classification and standardization of wages of Government employees consisting of three members of the Senate and three ex-members of the House of Representatives: The Chairman of the National Service Committee has been notified orally by the Vice-chairman that when said Commission reaches the consideration of engineers' salaries in the Government service, request will be made for assistance of Engineering Council. As it is probable that this request will be received prior to the June meeting of Council, it is recommended that action be authorized concerning the appointment of a suitable committee of Council to undertake this work.

MINING men in general- are a roving lot but not so Selwyn G. Blaylock. Immediately after graduation from McGill in 1899 he went to the Trail smelter and he is there today though he spent three or four years of his early professional life at other British Columbia mining centers. Either he sensed the great possibilities of the company of which he is now vice-president and general manager, or it sensed his; more probably both. Certainly the association was a happy and fortunate one.

ONE of the most important fields of investigation at the Diamond Research Laboratory in Johannesburg is concerned with improvements in metallurgical practices for the diamond mining companies, with particular reference to increased recoveries of the smaller industrial stones. Considerable work has been done on the possible application of flotation processes to the diamond industry.

As a part of a USBM-ASARCO cooperative rock-burst research program, a burstprone stope pillar at the Galena mine was successfully destressed. Destressing was accomplished by blasting a single line of long holes in the footwall of the vein. As a result of destressing, the pillar was fractured and softened; hence it yielded, releasing a large amount of stored elastic strain energy nonviolently. In addition, the high stress in the pillar was shifted out around the stope walls and in the sandfill. Both broad-band microseismic monitoring and seismic velocity surveys were used to evaluate the destressing test. The mechanics of destressing were determined by finite element computer model studies of destressing. Results of the field destressing test agreed remarkably well with the predicted results from the computer model.

Pyrite, pyrrhotite, chalcopyrite, and sphalerite from deposits distributed within the Piedmont and Blue Ridge provinces of North Carolina and adjacent areas were examined by atomic absorption spectrophotometry for cobalt, nickel, manganese, lead, tin, chromium, molybdenum, and gold. The ore samples were also examined petrographically. Cobalt and nickel, in general, enter pyrite and pyrrhotite rather than chalcopyrite and sphalerite. Manganese generally enters sphalerite rather than the other phases where an alternative is possible. The presence of tin in sulfide minerals was noted in a group of deposits east of the known occurrences of tin oxide (cassiterite) in the Kings Mountain belt, which may indicate the presence of a more extensive tin belt in the southeastern Piedmont than was previously recognized. Pyrrhotite from a group of four deposits in Jackson and Clay Counties, North Carolina, differs from pyrrhotite from other Ducktown-type deposits in having cobalt/ nickel ratios less than one, finer grain sizes, and colloform texture. These differences suggest that that this group of deposits has had a history different from that of the other Ducktown-type deposits studied. No significant conclusions could be made based on the distribution of lead, chromium, molybdenum, or gold.

The efforts of petroleum production engineers during the past year have largely concentrated upon ways and means of reducing operating investments and expenses in order that the industry may survive a period of low crude oil prices. Major progress was made in outlining and solving the technical problems pertinent to unit operation in order that executives and legal staffs may actually arrange operating contracts to effect unit operation. Consequent savings in development and operating costs, accompanied by increased recovery, will thus be obtained. Well spacing has received considerable constructive thought and study, from which practical results are assured in the near future. The control of edge and bottom waters has advanced in technique through the engineering work done in Yates, Hobbs and East Texas, and there is evidence of greater cooperative efforts between engineers to increase recovery from pools by mutual gas conservation. The use of pressure control by surface and bottom-hole chokes has become general practice to reduce gas-oil ratios. The study of bottom-hole pressures has led to new conceptions of proper utilization of reservoir energy and maintenance of pressure by natural means. Pressure gradients of flowing wells have been measured in practice and strides made to develop workable formulas for the flow of oil and gas mixtures through vertical pipes. The information thus obtained will permit the intelligent design of flow tubing combinations. Gas-lit and repressuring advancements have been few, due to overproduction from naturally flowing wells. Satisfactory unloading valves for gas-lift wells have been developed and consistent progress made in gas-lift displacement pumps. The necessity for producing wells at high rates of flow while producing large quantities of sand has resulted in radical changes in Christmas tree and separator designs for the Oklahoma City pool. The opening of wells to obtain potential production for proration purposes has been eliminated in the Yates and Hobbs pools by the application of engineering principles.

The Occupational Safety and Health Act of 1970, although providing no precise definitions of safe and healthful working conditions, specifies mandatory duties, and methods and procedures -- "to assure so far as possible every working man and woman in the nation safe and healthful working conditions." The dynamics of the workplace ad the dynamics of this coextensive Act both spring from the same source. Both require at any given time an application of the then con- temporaneous highest state of the art. Both are flexible, ongoing, adaptive, changing; both advance by a blending of experience and research.

THE Hog Mountain mine is a pyritic-gold property in the north central part of Tallapoosa County, Alabama, at an elevation of 800 ft. in the southern Appalachian region. It is 13 miles by a good secondary road from Alexander City, a station on the Central of Georgia Railroad. Since its discovery in 1839, the mine has been worked intermittently. The records of past operations are few and are scattered over a long period of time; however, available information indicates a production of approxi-mately 12,000 oz. of gold prior to the present company's activities, which started in 1933. Additional 7844 oz. has been produced under the direc-tion of the present management. The ore from stopes has averaged 0.200 oz. gold per ton; the ore from development, 0.136 oz. gold per ton. Silver, copper, iron and sulphur are also present but to date are of minor importance. The grade of ore in comparatively narrow veins makes necessary extreme vigilance in the methods of mining.

Many months ago, the ME staff began thinking about what to put on the February cover of the Centennial Commemorative issue. We have considered photographs of mines, equipment, symbolic artwork and various collages. Our theme is "the next 100 years in mining" and the cover ideally should convey a related message or idea. All of us are convinced that there are many exciting technical changes that will be coming. But even so, we decided that, in our opinion, the engineer is the most vital factor. For this reason we chose to put a man on the cover of this issue. At first it was going to be the face of a man with whom each member could conceivably identify himself. It was one of the Bobs on our staff (we have four) who came up with the thought that since it's the future we are talking about, we should have a young man's or a student's face. Of course we firmed up our idea at the ninth hour, and it was too late to canvass the mining schools. However, by a stroke of luck, we were rapping with a group of University of Arizona students on the terrace of the Pioneer Hotel on December 7, 1970, and met Dave Bolles.

The Glidden Co., a newcomer to the mining industry, will be putting on stream its Lakehurst mine and concentrator this spring. Ilmenite-bearing placer sands will be mined and concentrated in a spanking new combination gravity, magnetic and high-tension separation plant. Glidden, well known as a paint, chemical and food manufacturer, consumes titanium dioxide as pigment in its paint business. The commodity is produced at the company's Adrian D. Joyce Works in Baltimore from ilmenite purchased in India and Australia, The Lakehurst operation, handily located in Ocean County, N. J., will dampen any deficiencies in quantity or price which might occur from foreign suppliers. This objective is no overnight concoction of The Glidden Co., because the move at Lakehurst was preceded by an attempt to start up in Florida. That project was abandoned when it was found that the titanium dioxide values were largely in rutile-a mineral which does not lend itself readily to the digestion process of the Baltimore chemical plant.
