AMONG electrical manufacturers, interest in the outlook for copper supplies has not diminished despite signs of a healthier market following price decontrol. Reason: Electrical utility industry output is expected to grow at an average annual rate of 6 pct for the next 15 years. A more graphic description of the growth ahead is given in the Eighth Quarterly Report of the Director of Defense Mobilization as follows: "Power generating capability, which amounted to 63 million kw at the time of Korea, now stands at more than 81 million. The established goal for installed capability at the end of 1955 is 116 million kw. Orders already on the books of power equipment manufacturers, if fulfilled on schedule, will bring installed capability to over 123 million kw by the end of 1956-and more orders for equipment are yet to come." These statistics portend an impressive requirement for copper, not only for power plants and distribution lines themselves but for the multitude of industry and domestic end-uses.

The Stanrock mine of Stanrock Uranium Mines Ltd. is located on Quirke Lake in the Elliot Lake area of northern Ontario, about 25 miles north of Lake Huron. The property was developed and brought into production at a rate of 3000 tons of ore per day during the uranium boom of the mid-1950's. The mine workings are from 1200 to 2100 ft below sea level. Mining was done by the room-and-pillar method with 65 to 80% extraction. The plant is located at an elevation of 1400 ft above sea level. The orebodies are conglomeratic beds, 6 to 40 ft in thickness and dipping 5º to 40º. The ore is a quartz pebble conglomerate with a pyritized sericitic matrix. The ore minerals are brannerite, frequently intergrown with anatase or rutile, uraninite, and some monazite and minor coffinite and thucolite. Sulfides constitute 5 to 10% of the ore as pyrite with minor amounts of pyrrhotite, chalcopyrite and galena.

For many years the water pressure test has been used as a normal procedure to investigate the hydraulic characteristics of rock masses and discontinuities. Although the test has given evidence of problematic areas, the nature of flow and the so called equivalent permeability are seldom seriously affected by the testing tecnique. In order to improve the information on these points the Instituto de Pesquisas Tecnológicas de São Paulo - IPT, has developed an extensive program at laboratory and field research on the hydraulics at rock fractures. This paper summarizes the main items related to this research. Is shows that with only small improvements on field tests and some support of laboratory conductivity tests on natural rock joints it is possible to obtain a better understanding of the nature of flow in fractures, improve flow predictions and estimate the opening and hydraulic conductivity, as well as the transmissivity of natural joints or rock discontinuities.

Upon nomination of the President, _the following Committee on Membership was appointed: Karl Eilers, Chairman, Arthur. S. Dwight, Lewis W. Francis, Louis D. Huntoon, Arthur L. Walker. The following resolution was then unanimously passed: WHEREAS, the integrity and life of this nation is dependent upon its ability to successfully defend itself against foreign aggression and attack, and WHEREAS, it is necessary that the nation he properly prepared to the end that our untrained patriotic volunteers he not uselessly slaughtered and our country disgraced and defeated, be it therefore RESOLVED: That the Board of Directors of the American Institute of Mining Engineers believe that compulsory universal military training should be at once instituted and that adequate, complete and immediate preparedness, should he provided. BE IT FURTHER RESOLVED: That, we believe that thorough and complete preparedness in the army, the navy and the industries of the country is vital; anything less is unsatisfactory and inefficient and may result in disaster to the nation.

During the past 20 years the Westinghouse Electric & Manufacturing Co. and the General Electric Co. have collected a valuable library of some 9000 volumes on electricity. The collection was intended especially for use in patent searches and is particularly rich in patent material. Files of all the principal patents relating to electric light acid power issued by America, England, France and Germany, are present, together with copies of the patents owned or controlled by the two companies. Another feature, and one of unusual value, is a series of volumes containing the records of the important adjudicated patent cases of these companies and their predecessors during the past 25 years, and forming a storehouse of electrical history. There are also files of about 100 electrical periodicals. It is a pleasure to announce that this collection has now been presented by the owners to the Engineering Societies Library. This gift, which was arranged through Mr. Charles A. Terry, Vice-president, Westinghouse Electric & Manufacturing Co., and Mr. Charles Neave, Counsel,
