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.

The treatment of unaltered western phosphate ores by both wet and dry methods is discussed. The objective of the beneficiation is to produce salable Phosphate rock ( 31% P205), with an economic recovery of P205.

Geophysical exploration for engineering purposes is conducted to decrease the risk in encountering site uncertainties. Such studies are needed in construction of underground facilities. Current responsibilities, opportunities and challenges for those with geophysical expertise are defined. These include: replacing the squiggly line format, developing verification sites for method evaluations, applying knowledge engineering and assuming responsibility for crucial national problems involving rock mechanics expertise.

The 1938 production for all of Rumania amounted to 48.984.200 bbl., as compared with 53.239.500 bbl. in 1937. which represents a drop of 4.255.300 bbl., or 8 per cent. Of the various fields. there are only two major increases in production—Baicoi-Tintea with 3.092.400 bbl. And

Phosphate deposits in Florida are a possible source of byproduct uranium. In this paper, the distribution of uranium in several recently mined areas is described. Flowsheets are established for several mines describing how the uranium becomes distributed during the beneficiation of the phosphate matrix.

The most notable development in oil and gas operations in Montana during 1938 were extensions to the Kevin-Sunburst and Cut Bank fields. No new fields were discovered, although about 20 widely scattered wildcat wells were operated. Within or adjacent to proved fields about 100 wells were drilled, resulting in 81 oil wells and 14 gas wells. In general, production activities were below those of 1937, largely because of market conditions. Markets for crude were improved late in the year by construction of refinerirs at Pocatello, Idaho, Spokane, Washington and Cut Bank; and also by price concessions. However, demand was much

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.

So, beyond and above the immediate and tangible ends of membership, ever-present and evident, selfish and generous alike; beyond and yet at the root of that genuine affection for our association which is so strong in many of us, there lies earnest sympathy with the ultimate and essential purpose of its being—that to which as a nucleus all other purposes are but contributory—which is, to

Extended discussions, by inviting attention to problems affecting the conservation of natural resources, have encouraged investigations as to their sufficiency, with the general result that the more thorough the examination, the less cause appears for anxiety as to the exhaustion or serious depletion of these resources.
