The production of petroleum in New York state in 1942 amounted to 5,410,000 bbl. This represents an increase over each of the four preceding years, and, with the exception of 1937, is the largest production since the peak of over six million barrels in 1882, shortly after the discovery of oil in Allegany County. The oil industry in New York is virtually stabilized and there has been little or no exploration for new sources of supply in recent years. The boundaries of the present fields were established more than 30 years ago and since then no additional reserves have been found. Deep drilling for natural gas during the past 10 years both within and without the oil fields has failed to find oil in quantity below the present producing sands of Devonian age. Oil Since 1882, the New York fields have produced approximately 140 million barrels of oil. Of this amount, 65 million was produced up to the year 1919 by ordinary pumping methods; that is, without flooding by water or the use of other secondary-recovery methods. In the year 1919, when a law was passed making the use of water-flooding methods legal, the oil production, of the state amounted to only 851,000 bbl. In the 23 years since 1919, there have been produced in the state 75 million barrels, or 10 million more than in the previous 37 years, which included the period of flush production. Price.—On March 26, the price of crude oil was raised from $2.75 to $3.00 per barrel, hut this increase had little or no effect on the number of wells drilled. In the Allegany field, which accounts for three fourths of the state's oil production, 1259 wells were completed in 1942, 7 less than in 1941. The smaller number of wells drilled was not only due to the shortage of labor but also was caused by the fact that in water-flooding territory a definite program for drilling wells is followed, and the flush period of an oil well is not usually reached in time to profit by any given price increase. Daily Production.—All of the oil wells in New York state, some 21,000 in number, are small producers. The average daily oil production is 7/10 bbl. per well. Under good flooding conditions, a maximum production of 5 to 8 bbl, a day is reached about one year after the flood begins to act on the well. In 5 years the daily production usually is less than one barrel. Although most of the oil in New York is produced by flooding, an estimated 2500 old wells produce without flooding. Some of these produce as little as 1/20 bbl. a day and are pumped only at intervals. The small producing Wells are mostly on lands leased to the larger oil companies and later will be included in a flooding program. At present, they are pumped only because the owners of the land insist on the royalty. Government Aid Needed.—Because of its good lubricating qualities, New York oil is one of those for which there is an insistent and growing demand, but even at its present price of $3.00 per barrel, many of the operators are producing at a loss.

THIS is a progress report of an experiment being undertaken in cooperation with the Bethlehem Steel Corp., the Crucible Steel Co., and the Rock Bit Sales and Service Co., involving heat treatment of the shank ends of drill steel. This experiment is being conducted by the U. S. Bureau of Mines in its experimental mine, Mining Research Branch, Bluemont, Va. The purpose of the experiment is to determine the effect of an increase in the time the steel soaks in the furnace during the hardening heat. It has been thought that increasing this time produces a soft zone below the lugs resulting in a metallurgical notch that causes early failure. Each of the steel companies furnished enough 11/4 - in. straight carbon, hollow, round steel to make up 10 sets of drill steel, in each instance the steel bars were from the same heat. These sets of drill steel, consisting of 2-ft, 4-ft, 6-ft, and 8-ft lengths were fabricated by the Rock Bit Sales and Service Co. Special attention was given to the forging of the steel to produce the best rods possible. The heat treatment of all thread ends was identical and followed the best practice. The heat treatment of the shank ends of five sets of steel from each company produced a soft zone 2 to 4 in. in front of the lugs. It was decided that possibly the best way to obtain this effect was not to overlap the hardening heat but to let the steel soak for an additional 30 min before quenching. Therefore the only variable in the test steels is the length of time the shank ends were in the furnace. The remaining drill steel shanks were treated as follows: Heat treatment in pyrometer-controlled furnace at 1550°F. Quenching oil at 105°F to 125°F temperature. Areas for heat treatment were; shanks, 11 in.; threads, 9 in. Time at heat, standard practice, 20 min for 11/4-in. steel. Actual drilling tests were made in greenstone, (a metamorphosed basaltic rock), and in epidosite. Greenstone has a specific gravity of 2.96 and a compressive strength of 44,200 psi. Epidosite has a specific gravity of 3.26 and a compressive strength of 63,100 psi. All drilling tests were made using a 31/2-in. column-mounted, automatic feed drifter, with a controlled air pressure of 90 psi at the throttle. Tungsten-carbide bits of 2 in. diameter were used for all drilling. Contrary to expectations the drill steels that were allowed to soak for the additional 30 min before quenching performed better than the steels that were heat treated according to standard practice. This performance, as shown in Table I, was especially noticeable in the drilling of epidosite. The "longheat" drill steels furnished by Company "A" drilled 154 pct more minutes than the "standard-heat" steel. Expressed in feet, the "long-heat" steel drilled 114.60 ft more before failure than the "standard-heat" steel. The "long-heat" steel furnished by Company "B" drilled 37 pet more minutes or 60.39 ft more before failure than the "standard-heat" drill steel. The effect of the long heat treatment was not as evident when the steels were drilling in greenstone (Table II). In greenstone, the increase in minutes drilled by the "long-heat" steel over the "standard-heat" steel was 47 pet and 1 pet, respectively, for Companies "A" and "B."

The Gulf Coast of southern Louisiana during the year of 1940 was subjected to an extensive exploration and development campaign, as a result of which 16 oil fields and about 38 new producing sands were found. Although this record of discovery appears in keeping with the rate of 1939 actually in amount of new proven reserves, it may fall short of that of the previous year. Only five or six of the discoveries rated as first-class or important fields at the close of the year. The most prominent new fields opened during the year were Neale field in Beaure-gard Parish, the West Cote Blanche field in St. Mary Parish, the Stella field and the West Bay field in Plaquemines Parish, and the Lake Salvador field in St. Charles Parish. There were many important oil-sand discoveries in proven fields, such as in the Bayou Perot field, the Golden Meadows field, the Iowa field, West Lake Verrett field, and the Venice field. During the year, 1047 weUs were drilled in southern Louisiana, of which 768 were completed as oil-producing wells, 17 as gas wells and 262 as dry holes. The Neale field in northwest Beauregard Parish is considered one of the most important discoveries of the year. The f~eld centers around the north half of sec. 26, 'Y.3 S., R.I I W., just north of the town of Neale. It was discovered by the Atlantic Refining Co., using reflection seismograph to locate the structure. Production was found in the second well drilled in the Wilcox sand on the downthrown side of a fault. The structure is known as the "Tepetate" type, being similar to that of the well-known Tepetate field. There were 12 oil wells and 3 dry holes drilled during the year. The Wilcox sand in this field occurs between 8350 and 8400 ft. and averages 30 ft. in thickness. The West Cote Blanche Bay field, in West Cote Blanche Bay, St. Mary Parish, is a 1940 discovery by the Texas Company, credited to reflection seismograph exploration. The oil is from two sands occurring at 3110 to 3140 ft. and from 4950 to 5020 it. Four wells were drilled during the year, three oil wells and one dry hole. The deepest hole drilled reached 9491 ft. without encountering salt or dome material. In Plaquemines Parish, south of New Orleans, the California company has a new field known as the Stella field. The sand was found at a depth of 7485 ft., and 5 ft. of perforations made a well capable of producing 486 bbl. of oil in 24 hr. through a 9.is-in. choke. The oil is 42" gravity. The discovery well was drilled to a total depth of 10,258 ft. and other producing sands were indicated. A good field appears assured, although only one well was completed within the year. The Lake Salvador field, in the center of Lake Salvador, St. Charles Parish, gives promise of being one of the most important discoveries of the year. The discovery well was perforated at 9775 to 9800 ft. making 850 bbl. of 33.7° gravity oil daily through a 1/4-in. choke. Three wells were completed in 1940 but few details have as yet been made available.he Gulf Oil Corporation apparently has a good field in its wildcat discovery in West Bay, Plaquemines Parish.

Discussion of the paper of E.. C. LEE, presented at the St. Louis meeting, October, 1917, and printed in Bulletin-No. 130, October, 1917, pp. 1825 to 1832. H. M. WILSON, Pittsburgh, Pa.-The statement ill the paper of T. T. Read, "Increasing Dividends Through Personnel Work;" that the offering of substantial money rewards for avoidance of accidents is much more effective than mere propaganda or education respecting accident prevention, is a, point fully substantiated in the experience of insurance inspection under workmen's compensation acts. The first year under the Workmen's Compensation Law in Pennsylvania, during which over 2000 mines were tinder the observation and protection of the inspectors of the insurance companies, has resulted in several inspections of each mine, a splendid cooperation .between the operators, the State mine inspectors and the insurance inspectors, and an average reduction in premium rate for insurance from $3.83 to $2.77, a reduction of more than $1 per $100 of payroll, on an average payroll of nearly $100,000,000, In other words, the insurance companies have

Thermal conductivity measurements of intact rock specimens do not reflect the effects of natural rock discontinuities, and large scale insitu tests are location specific and costly. To allow extrapolation of laboratory measurements to rock masses with discontinuities, the effects of discontinuities on rock thermal conductivity were measured using divided-bar techniques. The introduced discontinuities lowered the thermal conductivity in all cases, and conductivity decreased systematically with increasing roughness of the discontinuity. Conductivity increased with increasing pressure on the discontinuity.

The authors are to be complimented on using a novel and potentially helpful technique to analyze the effects of mine roof trusses. However, some criticisms of their application and analysis seem appropriate to further its acceptance. This discussion will deal with the normal structural analysis format covering: 1) material, 2) load, 3) structure, and 4) analysis. It will then briefly review the testing procedures and finally cover miscellaneous items.

IN connection with a research on gallium alloys, a method for the thermal analysis of very low melting alloys was developed, which appeared to be worthy of more than passing interest. As used, the method was suitable for work in the temperature range, — 72° to 250°C. However, with suitable adjustment, the method could be adapted for use over broader temperature ranges. The Rosenhain temperature gradient furnace,' adapted for low-temperature use, was the basis for the method. The gradient was set up in a stainless steel tube. The specimens were lowered through it at a constant rate while time-temperature or inverse rate data were taken. It was essential to maintain careful control of the top and bottom temperatures of the gradient. Also essential was good heat transfer from the walls to the specimen. This was accomplished by a liquid heat-transfer medium.

Study results are presented in which gaseous oxygen was dissolved in the leach liquor at concentrations of the order of 300 ppm. This oxygen-containing solution was injected into portions of a field being operated on a commercial basis with hydrogen peroxide as the oxidant. Comparative results indicate that uranium concentrations and production rates were essentially equivalent with these two oxidants.
