A NOTED Prospector Passes-Stories of the grizzled old prospector that discovered what turned out to be a famous and highly profitable mine, only to die in poverty through the shenanigans of "the Interests," are legion. It is pleasant, therefore, to be able to report that the discoverer of one of Canada's most famous mines was more fortunate.

The Lake Superior Mining Institute, Ishpeming, Mich. A. J. Yungbluth, Secretary. An Annual Volume of Proceedings, carrying papers presented during the year, has been published since 1S83, with the exception of the years 1S97, 1899, 1907, 1916, 1918, 1919, 1920, 1921, 1924 and 1927. No meetings were held during those years and conse-

THERE is always a difficulty in assigning limits to the scope of a science or art, and among the difficulties of that kind besetting practical or stratigraphical geology is that of determining what kinds of natural objects shall be considered as the goals of its search. The term mineral, in its broader sense, includes every solid, liquid, or

Arkansas' nonmetalliferous deposits are of many different types. The principal types briefly described in this paper are: clays, shales and slates; silica deposits; limestone and dolomite; barite; gypsum; celestite; nepheline syenite; greensand; phosphate; vermiculite; fuller's earth; bentonite; diamonds; sand and gravel. The future development of these deposits is expected to effect profoundly the industrial development of the state.

Eight different oil zones have been identified and produced at Santa Fe Springs, of which three or four are in turn divided into two or three parts. These zones, from top to bottom, are the Foix, Bell, Meyer, Nordstrom, Buckbee, O'Connell, Clark and Hathaway, or third Clark. While there has been some difference of opinion over this nomenclature with reference to the different zones referred to as Clark, it has no particular bearing on the water problems. Each of these oil zones has had waters of varying salinity associated with it, either within or at the bottom of the zone. Table 1 is a tabulation of the zones, their maximum thicknesses, salinity and heads of various waters. Surface waters are fresh, and of high head, giving artesian flow in some instances.

Wabush Mines is the largest single supplier of iron ore to the Canadian steel industry, with 42% of its 6 million tpy of iron ore production going to the company's two Canadian owners-The Steel Co. of Canada and Dominion Foundries and Steel Ltd. Six other companies hold interests in Wabush Iron Co. Ltd. These are Lykes-Youngstown, Inland Steel Co., Intrerlake Steel Corp., Wheeling-Pittsburgh Steel Co., Finsider of Italy and Pickands Mather & Co. Field work on Wabush began in mid-1957 when a long-range program of economic, geologic, and metallurgical investigations started. This work was followed in 1959 by the construction of a temporary camp and a 700-tpd pilot plant. At the same time, work was also started on a 38-mi railway connection to Ross Bay, Newfoundland.

Under the designations "industrial talc" and "soapstone" are included earth materials of widely different chemical and mineral compositions. Talc, the mineral, is a hydrous magnesium silicate, with a suggested theoretical formula H2Mg3(SiO3)4 or H2O.3MgO.4SiO2, which postulates 63.5 pct SiO2, 31.7 pct MgO, and 4.8 pct H20.18 Single grains or leaves of talc, however, seem to have variations in water content that range from 3.5 pct to more than 7 pct, as well as slight differences in the proportions of MgO and Si02.20 Most of the industrial talcs produced in the United States do not approach the composition given above (see Table 1), but are essen- [ ]

In Table 47, tonnages shown before 1869 are estimated. After that time they are partly estimated from the total tonnage handled by the Allegheny Valley Railroad from four counties, of which this was one. Several reports to state authorities give a few figures, all probably very low, as is shown by the return in 1880 to the Secretary of Internal Affairs. [ ]

During the year 1942 there were 66 wildcats drilling in Mississippi. One cored in oil sand, the Macro Drilling Company's Longbell No. I in Clarke County, but as yet it has not succeeded in recovering the oil. These drillings broughi to light five salt domes, two of which had heavy oil showing; one drilled by the Magnolia Petroleum Co. in Warren County, and

This paper records over twenty years' experience with the use of the Rheolaveur system in the United States, showing its ability to meet changing conditions caused by the dirtier mine output of present-day mechanical mining methods. Data are given on size ranges handled, number and capacity of units installed, maintenance experience, and operating results on two-product and three-product separations.

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.

IN an effort to obtain a better understanding of sintering in the presence of a liquid phase, it was decided to study the rate of capillary rise of a relatively low melting liquid metal in a higher melting metal powder compact. By assuming that the metal powder compact consists of a great number of parallel capillary tubes and that the flow of liquid

Robert Annan is an Englishman who started his brilliant mining career in Arizona, yet achieved the pinnacle of success in his native land when he became chairman of The Consolidated Gold Fields of South Africa. This story of his life, prepared in collaboration with the late Henry Carlisle, continues this fascinating biographical series of important personalities in the mining industry.

Results of a laboratory investigation of some sintering variables are presented. The effect on physical properties of mix component variation and rate of cooling of the sinter is illustrated by crush and tumbler test results and data of reducibility tests and microscopic examination of sinters are shown. The results of using solid additions in the mix to improve bed permeability are given.
