Mr. Vissac's study is very elaborate and complete and gives a clear idea both of phenomena occurring during operation of the feldspar jigs and results ob- tained by some of them in Europe. I have no intention of going into a complete discussion, but I would like to give a few comments about these results already

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.

ALMOST all the hazards productive of accidents are present in churn drill operation-exposed electrical cables, open machinery, moving parts located overhead, exposure to weather, and movement of heavy machinery-all are part of the job. But, a check list of danger spots and full use of countermeasures will produce maximum safety here, as on any other operation.

ISOMETRICAL drawing and clinographic projection are generally preferred to perspective drawings for representation of small objects or complicated mechanisms, as they present to the eye a sufficiently accurate picture of the object, while they possess great advantages over perspective in the simplicity and rapidity of execution, and the facility they give for taking measurements directly from the drawings.

Booz-Allen & Hamilton management consultants has recently completed a comprehensive study of Brazil's minerals and metals sectors for 40 leading international and Brazilian companies. The 220-page study describes the activities and Investments under way in 25 key commodities and assesses the current state of Brazil's economy, the impact on domestic minerals and metals industries, and government minerals policies.

Feeders and Grizzlies are links of the utmost importance in the chain of milling operations, but, hitherto, the close analysis granted to other equipment has been withheld from these machines. The development of. the self-clearing drop-bar feature, the result of many years' practical study of the problem, has made possible a machine which will

I HAVE striven to demonstrate to you as well as possible the method of bringing the metals of your ores to their ultimate perfection. But one cannot always do with gold that is found in the ores what is done with the other metals, for gold is not always accompanied by fine silver nor is it

EUGENE McAULIFFE, * St. Louis, Mo.-The method employed by the Engineer's Committee in arriving at a proper selling price for coal and coke represents hard painstaking effort based on a thoroughly scientific foundation; and the United States Fuel Administration can well point with pride to the work of this committee. The results so obtained placed

AS the available remaining properties of iron ore reserves on the Mesabi Range are opened up for mining, the various properties located under lake beds are brought nearer an active status. The actual physical problems involved in stripping these properties do not act as a deterrent so much as the legal and political problems that are encountered.

Through the remainder of this century, world consumption of fluorine per ton of primary aluminum produced will continue to be substantially reduced. Growth of the primary industry will offset some of the unit consumption, but demand for new fluorine sources will decline sharply. Continued application of dry fume scrubbing system will be the most significant factor in reducing demand.

RICHARD ore mine of the Colorado Fuel & Iron Corp. is an underground magnetite operation located in northern New Jersey approximately four miles northeast of the town of Dover, and 40 miles west of New York City. The mine is situated on the southeastern flank of one of the many gneissic ridges having a northeast-southwest trend

The effects of capital, operating and debt cost variations on project performance criteria are examined using a theoretical model and an actual case history. On an after-tax basis, financial measurements are found to be most sensitive to operating cost changes, somewhat sensitive to reasonable changes in capital costs and relatively insensitive to interest rate fluctuations.

CARL ZAPFFE, Brainerd, Minn. (communication to the Secretary*).¬Unless one has actually directed explorations for iron ore, it is doubtful whether the importance of Mr. Wolff's paper, the value of the information contained, and the large amount of detail work involved in what is set forth can be fully appreciated. It is indeed rare to get such a com-
