Safety considerations apply from two perspectives in conducting shaft inspections for production and service hoists. The first is to conduct the task more effectively while minimizing the possibility that shaft deterioration may go undetected. The second is to increase security and efficiency of the inspection team in fulfilling its duties.

WHEN asked a few weeks ago if we wished to visit the Coors plant at Golden, Colo., we agreed with alacrity being well acquainted with the high quality of Coors beer and having heard that the company was most liberal about sampling privileges. Instead of a brewery, we found ourselves in a pottery, the Coors Porcelain Co., owned and operated by the firm of beer fame. Our apparent disappointment was dispelled as the wonders of the porcelain products were unfolded.

Longhole sublevel stopes excavate ore with which the production geologist has only remote contact; therefore, predicting grade and tonnage from such a stope can be a problem. However, the longholes themselves yield data that can be used to improve those predictions. Here, a radial distribution method of weighting sample data is discussed, which is useful in forecasting grade and tonnage from certain longhole sublevel stopes.

Successful preliminary experiments at the University of North Carolina indicate that computers can provide speedy, accurate identification of the mineral content of rock samples. In just two minutes, the University's Univac 1105 computer solves the complex equations that would often require more than four hours using conventional methods. In addition, the computer is frequently spotting minerals that a geologist might miss simply because he wasn't looking for them.

EVERY mould, of whatever kind it may be, must have an entrance appropriate to the material if it is wished to fill its inner space with bronze or other metal. It is likewise necessary that it have vents, that is, air holes, for there is nothing that is not full of air even though it be called empty. Now, molten bronze is a material that has an immediate effect because of its heaviness, and because it is as hot as fire or even hotter,
