The following method of plumbing a shaft, suggested itself to me as practicable and at the same time more accurate than the methods commonly employed. It consists in obtaining a longer base by suspending the plumblines from the extreme corners, lengthwise of the shaft, and repro-

In a recent publication in the SME Transactions of September, 1975, Volume 258, entitled "Potential for Further Lowering Sulfur in Intensively Cleaned Coal at Mines", the writer discussed: (1) technical findings useful for the management of reserves to further lower sulfur in intensively cleaned coal, and (2) a future coal preparation plant concept for the intensive cleaning of sulfur. The purpose of this technical note is to ( I ) illustrate the nomographs that can be formed when recovery is phased in with previous work, (2) make note of the powerful potential for predicting future cleaning performance in unmined areas, and (3) discuss resulting mathematical interrelationships.

AS in former years, Pechelbronn, in Alsace, was the most important producer in 1936, with 484,453 bbl., of which 283,151 from drilling and 201,302 from mining showed a slight increase in comparison with the preceding year. Gabian, in France and Tliouanet, in Algeria, are nearly exhausted. At Gabian, four wells drilled in intermittent exploitation produced during the year 2893 bbl. Four wildcats, one of which is producing, constituted all the activity in research on French territory. In Morocco, some wildcats have been drilled in search for new fields and exploratory drilling has been done in Tselfat and in Djebel Bou Draa in known fields, but the results have been inconsiderable. In Tunisia there was a gas outburst in Kebir 1, which is the first practical result obtained. In Madagascar, the Andrafiavelo region has been left and a new region has been tried in Folakara with the Tsimororo. In French Equatorial Africa, one drilling is in progress.

For many years large mining companies were able to finance nearly all of their capital requirements from internally generated funds. However, during the last decade, funds needed for capital expenditures, dividends, and scheduled debt retirement have grown faster than cash flow. As a result the minerals industry has had to rely increasingly on other sources of funds. Getting the capital for new mining projects is a challenge, particularly for smaller companies. New methods of financing and new variations to old methods have been developed and more are needed. Commercial banks are short-term lenders. By policy their loans are limited to low risk loans-those made solely on the borrower's general credit, and secured loans where cash flow is sufficient to provide repayment within a comparatively short term. To maintain liquidity, banks prefer to make loans of less than seven years' term. If a longer loan is needed an insurance company or pension trust may take the long-term part.

AMONG electrical manufacturers, interest in the outlook for copper supplies has not diminished despite signs of a healthier market following price decontrol. Reason: Electrical utility industry output is expected to grow at an average annual rate of 6 pct for the next 15 years. A more graphic description of the growth ahead is given in the Eighth Quarterly Report of the Director of Defense Mobilization as follows: "Power generating capability, which amounted to 63 million kw at the time of Korea, now stands at more than 81 million. The established goal for installed capability at the end of 1955 is 116 million kw. Orders already on the books of power equipment manufacturers, if fulfilled on schedule, will bring installed capability to over 123 million kw by the end of 1956-and more orders for equipment are yet to come." These statistics portend an impressive requirement for copper, not only for power plants and distribution lines themselves but for the multitude of industry and domestic end-uses.

The total production of crude oil in Canada showed only a small improvement in 1936 over 1935, but developments of great importance took place in Alberta on the west flank of the Turner Valley field in the foothills southwest of Calgary. These have led to renewed activity in drilling such as has not been experienced for many years, and undoubtedly this will result in a very considerable increase in the oil production during 1937.

J. W. RICHARDS*(South Bethlehem; Pa.).-The brass industry would find it very profitable to subsidize researches on the purely scientific determination of the thermophysical properties of the brasses. The data we need most in connection with the brasses are the vapor tension of the zinc from the brasses at different temperatures, the heat of combination of zinc With copper to form different kinds of brasses, and the latent heat of fusion of these brasses at the melting temperature.

After an absence of over two years, the writer returned to Leadville in March, 1890. The change which had taken place in the conditions of smelting during so short a time seemed almost incredible. Lead-carbonates had been still further replaced by refractory sulphides, and clean dry ores had been crowded out, to a large extent, by magnesian " fines."
