(Read at the Wilkes-Barre Meeting, May, 1877.) IN vol. 33 of the Proceedings of the Institution of Civil Engineers, London (part 2, for 1870-71), may be found a statement of the cost of two blast furnaces, together with a somewhat detailed description. The attempt will be made in this note to restate these items of cost, so that the information may be rendered perhaps more accessible to our members than in its present place of record, and also in order that the items may be more intelligibly compared among themselves, or with similar items in other cases.

Chan and Goodman (1983) presented a procedure for simulating joint traces and identifying key blocks on an excavation. This paper defines six measures of support requirements that characterize the number and dimensions of key blocks, taking into account the frictional properties of joints and actions of support systems. When correlated with case histories, these measures of support requirements can help in choosing an optimal design for shallow excavations in discontinuous hard rocks.

JOULE-THOMSON coefficients for two natural gases were determined at pressures up to 600 lb. per sq. in. throughout the temperature interval between 70° and 310°F. From these primary data and available information relating to the isobaric heat capacities of the components at infinite volume, the heat capacities of these gases were computed throughout the above-mentioned range of pressures and temperatures. The enthalpies of the gases were computed as a function of state and the results compared with values obtained by several methods of prediction currently available. The results are presented in graphical and tabular form.

At the Pennsylvania Steel Works, Steelton, Pa., a series of trials has been made with oil as fuel in steel-heating and open-hearth steel-furnaces with the following results : First Trial.—Hot 14-inch ingots, six to a charge, were heated in two Siemens' heating furnaces in the blooming mill, the oil being put in first in March, 1888. The oil used had been partly refined, so that the paraffine and some of the naphtha were removed. During a run of six weeks the consumption of oil was about 61/2 gallons per ton of blooms, including the oil required to keep the furnace hot over Sunday.

Longwall methods to mine coal in the United States provide the potential advantages of greatly increased productivity, improved safety, and a higher percent recovery. However, use of longwall systems during the past 10 years has increased much more slowly than was anticipated. This paper discusses some of the problems inhibiting the increased use of longwall systems and a proposed research program to address one of the most critical problem areas.

Curious petroleum, mining and metallurgical engineers together with oceanographers, geologists, geophysicists and those in related disciplines, some 11,500 of them, poured into the Albert Thomas Convention Center in Houston, Tex. to see, and learn. This year's successful Conference, held April 22-24 featured a technical offering of 145 papers presented at 28 sessions. In addition, a total of 500 exhibits were provided by 260 companies.

The 38 companies listed below are those substantially engaged in the mining of metals, non- metals, or coal which appeared among the country's top 500 (on the basis of sales volume) listed in the July 1966 issue of Fortune. General Motors, with $20.7 billion in sales, heads the entire list, and a prominent member of the mining industry, Island Creek Coal, occupies the 500th spot with sales of $109.6 million. The lists of "industry medians" following mining's "Top 38" reveal how well the mining industry fared in 1965 in various salient categories of business performance.

The October meeting of the Mining and Geological Society, Lehigh University, was held in the Eckley B. Coxe Mining Laboratory, and was called to order at 8:15 p. m., by President R. L. McCann. After the reading of the minutes of the previous meeting, a short business session was held, for the purpose of electing a Vice-President to succeed G. S. Borden, who has left college. Nominees for the office were: H. J. Sloman, P. S. Justice, L. Sargeant. Dr. F. F. Hintze, of the Geology Department, was elected a member of the Advisory Committee, which now consists of the President-

In order to isolate the effect of an element on some property of an alloy, the effect of the other alloying elements must be elimi-nated, either by reducing their quantity to the extent that they may be neglected or by determining the specitic effect of each. The success of Grossmannl in calculating hardenability from chemical composition by means of factors suggested such a
