Nothing has disturbed the copper- lead-zinc producers in recent years more than smelter tolerances set by some states. What hurt most, copper spokesmen told the Government, was the Government's own erroneous estimates of smelter pollution controls. Government charts indicated that 23 firms smelting copper, lead and zinc may need to invest about $108 million by fiscal 1976 to control stack emissions. The copper industry's independent study, however, indicates that the required controls could cost as much as $550 million to install and $200 million a year to operate.

G. K. BURGESS, ? Washington, D. C.-At the Bureau of Standards it was decided, in order to study the high-aluminum end of these curves, that efforts should be made to prepare pure aluminum, and the promise of getting aluminum, practically free from the two elements that have such great effect in very small quantities, namely, silicon and iron, and which

After a year-long study comparing existing crafts and techniques for ocean exploration with the future needs of oceanologists, the University of Pennsylvania's ocean engineering research team has come up with a system proposal for prolonged deep-sea exploration. Given the assumption that it will be necessary to re-explore our oceans every 25 years or so, engineers from the University's Towne School of Civil and Mechanical Engineering believe the best sys- tem for future ocean exploration would consist of a stable, manned surface ship operating and controlling two types of vehicles-an unmanned untethered craft for broad search missions, and an unmanned, tethered vehicle for detailed work.

The outstanding development in Colorado in 1938 was the completion of the discovery well of the Wilson Crcek structure in Rio Blarlco County, on the western slope in the northwest corner of Colorado. Last year the Transactions (volume 127) carried an account of the discovery of oil in the Morrison sand in the Wilson Creek structure, in the joint test by The Texas Company and The California Company.

TODAY the tractor-drawn carryall scraper has a very important role in the Open Pit div. of Inspiration Consolidated Copper Co. Carryalls have already moved over 3 million tons of material at costs comparable to or lower than for conventional truck and shovel operation, and a major program of scraper stripping and ore production schedules has developed from early isolated scraper applications.

Discovery of a hitherto unsuspected extension of the Vermilion range iron formation in Northern St. Louis County, Minn., has been announced by the director of the State's geological survey, Dr. George M. Schwartz. USGS aeromagnetic maps show that the Vermilion range curves southeast from the Tower-Soudan area into the wilderness between Embarrass and Bear Head Lake. Dr. Schwartz believes that this new information justifies considerable exploration and drilling for iron ore in an area of about 20 sq miles southeast of Soudan. The aerial maps were a result of a three year USGS-Minnesota Geological Survey aerial search for iron formations in a 30,000 sq mile area in northern Minnesota.

It has been the custom, from the earliest time, to grade pig-iron by the appearance of the fracture; and although, since the pneumatic and open-hearth methods of steel-making have come into existence, chemistry has been called to the assistance of the steelmaker in selecting material for his use, the consumers of forge- and more especially of foundry-iron, still rely almost entirely, as they did a hundred years ago, on the appearance of the fracture of the pig to guide them in the choice of iron. To this rule, however, each year sees more exceptions; and there are now many foundry-men

Some of toe magnetic properties of minnesotaite (general formula: Fe3(OH)2Si4O10) were examined. Toe paramagnetic susceptibility values at various temperatures were determined from toe slope of toe magnetizing curve. These values were then compared with toe theoretical values estimated using toe Bohr magneton numbers for toe paramagnetic ions contained in toe missesotaite.

These districts are limited approximately on the north by the railroad from Salisbury to Ashville, and comprises the counties of Alexander, Catawba, Burke, Rutherford, McDowell, Cleveland, Lincoln, Polk and Henderson in North Carolina, and Greenville, Spartanburg, Union and York in South Carolina. The occurrence of monazite at Amelia Court House, in Virginia, belongs evidently to the same geological system, as its distance from the Alleghenies corresponds with that of the above-mentioned districts, and all the stratification runs parallel with those mountains.
