The Howe Memorial Lecture, in memory of Henry Marion Howe, Past President of the Institute, was authorized in April, 1923, as an annual address to be delivered by invitation under the auspices of the Institute by an individual of recognized and out- standing attainment in the science and practice of iron and steel metallurgy or metallography, chosen by the Board of Directors upon recommendation of the Iron and Steel Division. The following were the Howe lectures and lecturers for the years indicated: 1924 What is Steel? By Albert Sauveur.

The control of dusts and fumes of submicron size is involved in many process industries. This paper presents in tabular form the quantitative data from a number of metallurgical operations and discusses allowable discharge in terms of effluent-weight ratio. Typical installations for recovery of stack effluents are cited.

A fast, easy, and inexpensive method of determining the consolidation of overburden in surface mining operations through seismic analysis has been developed. The method involves use of a refraction seismograph which measures overall consolidation of subsurface materials, including such factors as rock hardness, stratification or lamination, fracturing or jointing, and the degree of weathering or decomposition. It also is possible to determine the thickness of various layers of subsurface materials to depths exceeding 100 ft.

Oil production in South Arkansas in 1936, estimated to have totaled 10,654,940 bbl., showed a decline of 484,400 bbl., or a little more than 4 per cent from 1935. There are no proration restrictions, as practically all wells reached the pumping stage years ago. Although a new shallow field was discovered in Nevada County, and a deep producing horizon

For the benefit of those of our members who are considerable holders of securities, but owing to their isolated situations are not in close touch with the metropolitan market and current quotations, we are publishing two very interesting graphs, showing the course of the bond and stock markets in New York over a long period. These graphs are furnished through the courtesy of the financial department of the New York Tribune.

Data about production are practically non-existent before 1860. The Census of 1840 reported a small amount, and a number of small mines were opened in the forties, all of the coal being used locally, or hauled to consumers in wagons. Tonnages shown in Table 72 are estimated from those for which authority is given. Railroads reported coal tonnages carried in the state in 1878 and subsequent years for years ending June 30th;, it is not stated that the tonnage originated in the state. Considering this fact, and the considerable amounts used locally, the tonnages given in Table 72 are certainly not larger than the actual amounts produced.

(Under this heading will be published notes sent to the Secretary of the Institute by members or other persons.) The governing body of the Imperial College of Technology, London, S. W. (Royal School of Mines), will shortly proceed to the appointment of a Professor of Metallurgy. This important Chair has been filled in the past by such eminent metallurgists as John Percy, Sir William C. Roberts-Austen, and others. Inquiry has been received at the office of the Institute for an engineer to examine a mica, deposit in one of the New England States. The position of converter blower at. a side-blow Bessemer steel casting plant is vacant.

A roof bolting theory and structural model are presented which explain the success of most roof bolting installations as the creation of a competent roof bolt reinforced rock arch within the immediate roof rock overlying an underground opening. Likewise, the failure of some bolted mine roofs can be explained as a failure to create a structually competent rock arch by roof bolting.

We have devised a multivariate statistical model useful to interpret data from exploration geochemistry and also pertinent for the analysis of data from petrology, paleontology, and other geological fields. The model is applied to several simulated cases in order to compare anomaly recognition by inspection and by quadratic regression.

The Glenharold mine is a multiple seam dragline operation where many different stripping methods are employed. This paper describes the production operations of over-burden removal, coal loading, and haulage. Emphasis is placed on the methods used to uncover fie seam using draglines, scrapers, and a small shovel.

Most lead-zinc mines worldwide have moved to further mechanized techniques to boost productivity, improve safety, and lower costs. The mining session, chaired by S. C. Fall, NL. Industries, and C. J. Beattie, Callahan Mining Co., reviewed mining methods at five operations in the US, Australia, Peru, and Japan. Where massive sulfide-type and irregular ore bodies are encountered, resourceful operators have modified and varied the mining method with the localized ore zones. In all cases, mechanization of operations has registered gains in productivity.
