The four different modes, more or less practiced for subdividing slag (that is, producing slag sand), are the following: 1. Crushing the slag from the lump in Blake's crusher, by edge runners or other suitable means. 2. Blowing water, steam, cold or hot air, into the stream of viscous slag whilst it runs from the furnace. So treated, the slag takes

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 outstanding 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

BRITISH success in extracting significant quantities of germanium from gas works flue dusts has been one of the prime forces in promoting similar research in the United States. Pittsburgh Consolidation Coal Co. and Pennsylvania Coal & Coke Co. are two of the larger U. S. firms with germanium from flue dust research programs. British interest in germanium started in 1933 when V. M. Goldschmidt reported that some coals from the Yard Seam of Northumberland and Durham contained 30 to 50 ppm of germanium.

IN the worldwide search of buried orebodies and for entirely new areas of mineralization, geo-chemistry is taking on an increasingly important role. Indeed, geochemistry itself is splitting into various specialties-hydrogeochemistry, pedogeo-chemistry, and biogeochemistry. This article primarily relates to developments in these fields in British Columbia, but many of the remarks are applicable to the whole continent.

EUGENE WESLEY SHAW, ? Washington, D. C.- (Written discussion?).-Paraffin earth is of especial interest because of the apparent difficulty of determining its chemical nature. I have submitted specimens to three chemists at different times with suggestions as to special tests that might he made. The results are indicated in the following reports:

Wildcat drilling operations in Montana during 1933 did not yield any discoveries of oil or gas that were of major importance. There was comparatively little drilling in the older proven fields, as most of the interest was centered in the Cut Bank field, where 44 wells were completed. The total number of wells completed in the state during the year was 79, of which 62 were productive of either oil or gas.

Long pipelines handling suspended solids find wide use throughout the mining industry. In phosphate, iron ore, and clay mining; in hydraulic stripping of overburden; in tailing disposal; and in transferring concentrates between plants pipeline transport may prove cheapest material handling method. One drawback is necessity for providing attendance at booster stations, both for control and for protection of pumping equipment from sudden surges and failures. Thiele Kaolin Co. in Georgia has come up with an installation where instrumentation does this job automatically, efficiently, and economically.

There is an ongoing need for the abstracting and coding of new information in the energy and environmental studies field for addition to the BIRS system. There are approximately 3000 bibliographic entries coded into the BIRS system. The bibliographic retrieval system was designed to be run by the general data management System 2000. The information system with entries of coal research, land reclamation and other energy and environmental studies is up and on line. As more entries are coded they are loaded into the system.

IKE'S amiable expression and apparent sincerity impressed AIME members as did the theme of his talk. Cautioning against the gradually increasing power of the federal government, he said: . . . "freedom as we know it is in no greater danger from without than it is from our own lack of understanding of this creeping paralysis from within." Next February, it will be three years since he uttered these words at Annual Meeting welcoming ceremonies, but the theme was oft repeated in his winning campaign. This brush with the exalted, brief though it was, makes Washington look friendlier to many AIME members than it has for years.
