The North Central Texas district, as known to the oil fraternity, is the area producing from sands and limes of Pennsylvanian age, roughly embracing the territory lying between Fort Worth and Abilene in an east-west line, and between the Red River and the Llano Mountains in a north-south line. The history of oil development in North Central Texas during the year 1927 is briefly reviewed in the following paragraphs. Brown County New discoveries and development in Brown County centered mainly around the Fry pool, located in the west central portion of the county. Important discoveries for the year were: Shoupe No. 1 John Byler, discovery well of the Byler pool, located 2 miles south of the Fry pool which camc in early in February, 1927, at 1262 ft. for 90 bbl. in the Fry sand of upper Strawn (Pennsylvanian) age. Rosenfield No. 1 P. Davis, discovery well of the Smith-Ellis pool located 1 1/2 miles northeast of the Fry pool, came in March 7, in the Fry sand from 1277 to 1279 ft. for 30 bbl. initial. Pandem Oil Corpn. No. 1 Mrs. T. Hutton, located 1 mile east of the Smith-Ellis pool, came in in December in the Fry sand from 1119 to 1130 ft. for 45 barrels. The Fry pool passed its daily production peak of 25,000 bbl. during the first part of June, and declined to a daily production of 5100 hhl. by the close of the year. The oil recovery from the Fry pool up to Jan. 1, 1928, slightly exceeded 4,000,000 bbl., averaging 4700 bbl. to the acre. over the entire pool. The Smith-Ellis pool passed its daily production peak of 5300 bbl. in Octohcr, 1927, and dropped to 3600 bbl. by the close of the year. The possibilities of the Byler pool will be unknown until the area is fully drilled up. In the Blake pool, production passed 2,500,-000 bbl. for the year. The per acre recovery in this pool up to lkc. 31, averaged slightly over 5000 barrels.

Downtime cannot be tolerated on electric shovels whose cost may approach or exceed $400,000 each. The same may be said for larger-variety off-highway trucks which require an operational expenditure upwards of $50 per hour. One company, for instance, in order to ensure a more continuous operation, has specified centralized lubrication for all of its new equipment. In wet or dry weather, the mining of asbestos can place undue strains on machinery and other equipment. When the mineral is dry, its dusty, loose fibers work their way into crevices, and when wet, the glutinous asbestos may adhere to axles, gears and other wear components. Such conditions are multiplied during the extreme cold winters of eastern Canada. It is more difficult to lubricate and maintain equipment, and erosiveness becomes more punishing to wear parts. Resultant breakdowns rapidly drain off profits.

Lineament and fracture analysis have enjoyed a resurgence of interest over the last several years, particularly since the advent of the Landsat series of Earth resources satellites. Some applications for lineament analysis include mineral, petroleum and ground- water exploration, engineering studies such as highway routing, mine roof stability, dam and power plant siting and general tectonic studies. The needs of each study may be different, but the general problem of large masses of data is common to all. Methods for efficient handling of the information and some statistical methods for its evaluation are discussed. These include comparing the lengths of the fracture population against known distributions, trend surface analysis of fracture lengths and number per unit area and multivariate analysis of rose diagrams. Examples are shown in an experimental program for predicting the presence of reef structures, areas of potential petroleum production.

Radiation grafting of ion exchange structures contains ion exchange groups but may consist of neutral groups. High energy grafting of monomers on to polymers has-been known since 1950 (1.2); manufacture on an industrial level was-begun in 1970.(3) Proper choice of substrate and monomer will produce various ion exchange membranes with differing physico and chemical properties. Grafting a selected monomer to the proper polymer will provide selective ion exchange with assured chemical protection of the substrate. Ion exchange systems utilizing radiation grafted structures to polymers have been fabricated to "capture" gold from drag-out and rinse water and silver from cyanide rinse water. Other ion exchange systems can feasibly be produced to remove other precious metals. Rotating Cathode Technology is used to recover the metals from their concentrated eluating solutions as pure metal foil.

In May, 1878, I had the honor of presenting to the Institute, at the Chattanooga meeting, some observations upon the heat of the Comstock Lode, and since then the subject has attracted some attention and criticism, in the course of which, L have observed errors of apprehension which I beg leave to correct now. Mr. John Arthur Phillips discussed it before the Geological Society, his paper being printed in the Quarterly Journal for August, 1879." His criticism is based upon that part of my paper in which I quote a number of analyses of the mine waters, to illustrate the fact that the heat does not come from the oxidation of pyrite. I pointed out that these waters contain only an insignificant proportion of sulphuric acid, and not enough to account for even one per cent. Of

All of the production for Ecuador during 1940 came from the Santa Elena Peninsula, Province of Guayas; the major portion coming from the Ancon field, which is controlled mostly by Anglo-Ecuadorian Oilfields, Ltd. A small amount was produced from the shallow pumpers and pozos, or oil pits, at Cautivo-Achallan, Carolina, Santa Paula, Concepcion, El Tambo and Mina Tigre. Considerable exploration was carried on in the country during 1940 and numerous concessions were in force, as shown by the accompanyiag map. Anglo-Saxon continued its exploratory work in the Oriente by surface geological methods and some geophysical surveys. It is understood that this concern did considerable airplane mapping. International Petroleum, on its large concessions between the Andes and Pacific Coast, did considerable surface work as well as some geophysical. No exploratory test wells were drilled by either of these

The petition for the formation of a Tulsa Section was granted. The final budget for the year 1917, and the tentative budget for the year 1918, were adopted. The Secretary was instructed to continue to send the Bulletin to all members whose dues have been remitted on account of their being in the war service, but to hold the Transactions and send them on request to the address furnished for the purpose. The issues of the Bulletin were presented to the Federal Fuel Administration, at its request, with the compliments of the Institute. Fifty-nine Members, five Associates, and fifteen Junior Members were elected. The resignation of one member was accepted. The clues of four members who are on active duty at the front were remitted. An extension of time for the payment of clues was granted to four members, upon request.

The 114th (New York) Meeting of the Institute will be held in the third week of February, 1917. The Committee on Papers and Publica- tions has set Dec. 1,1916, as the closing date for the receipt of manuscripts intended for this meeting. Manuscripts must be received by the Secretary on or before this date. If they are sent through members of the technical committees they must be sent to those committees enough in advance of the time to be forwarded and in the hands of the Secretary by the time specified. While Dec. 1, 1916, is the final closing date, it is a great advantage to get papers in as much before that time as possible as it enables them to be submitted in proof form to their authors. Papers received on or before

Before Capitol Hill hearings, primary metal producers are often called "concentrated industries" because there are relatively few companies in each category and most of them are large corporations. Capitol Hill still looks on large companies as inherently wrong, but there are about as many arguments one way as the other. Encourage Imports? Now comes Assistant Attorney General for Antitrust Richard W. McLaren to say that imports of metals and other basic materials should be encouraged to create competition for the concentrated industries here at home. Cloakroom analysts are wondering how this ties in with President Nixon's cabinet task force studying the copper price structure. This is chaired by Dr. Hendrik Houthakker, a member of the White House Council of Economic Advisers who has also indicated that the use of imports to pull down prices may be one way to create less inflation.

An understanding of the nature of yield zones surrounding coal mine excavations is fundamental to the design of mine support systems. Various methods have been designed for investigation of underground rock masses and an extensometric technique, the Magnetic Rod Extensometer, has been developed to overcome inherent design limitations in existing equipment of this type. This paper refers to the prototype form of the extensometer and details changes designed to overcome a variety of drawbacks indicated by routine use of the equipment. The principal change has been one of manual to computerised data acquisition and presentation in the laboratory phase of the system. This has dramatically reduced the time taken to process underground measurements and produce numerical and graphical results. The revised Magnetic Rod Extensometer represents an integrated instrumentation system that combines speed and accuracy in all areas of data handling.

The smelter is often considered the flywheel of the copper industry. No other unit can produce such a uniform product from so many starting materials. Direct-smelting ore, concentrate, precipitate, refinery slag, and scrap in almost any combination can be processed into blister or anode copper. Copper smelting practice has advanced little in the last century. It is still basically matte smelting, although the source of matte has changed from the blast furnace to the reverberatory furnace because of changes in smelter feed, and the Great Falls converter has been replaced by the Peirce-Smith converter. This lack of progress has continued because the economic forces required to produce change have not been of sufficient magnitude. Traditionally, the smelting, operation has required only about 10% of the total cost of producing copper from its ores and this minor cost item has not warranted change until recently.

THE Leadville tunnel, a Bureau of Mines project designed to unseal Colorado's rich but flooded lead, zinc, and manganese mines, is still being advanced, although the work is encountering severe difficulties. Work on the tunnel, begun in 1943, was dropped for lack of funds in 1945, and started again last September. The tunnel is one of the nation's toughest mining jobs. Fifty firms and individuals, who were asked to bid on the job of continuing be- yond the 6600-ft mark, didn't even answer. The work was finally taken over by the Utah Construction Co. of Salt Lake City. Since last September, the face has been moved 1000 ft closer to the flooded Leadville district mines, and to the hoped-for length of 17.300 ft. Some apparent success has already been noted, with an unusual decline in the water level in some major mine shafts reported this winter.
