The opposition is all kinds. There are extremists. There are quiet, sensible sounding folk who can twist numbers and facts to make their point. But they are all out to shut you down! Some of them are genuinely concerned about miners' impact on the environment. Others are just anti- society, anti-big business - small is beautiful - live naturally. The opportunity for them to make those statements on television was provided by us, the Uranium Public Affairs Task Force, as part of a media tour of the State of Idaho in May. We fielded four representatives of the industry and got 25 hours of television coverage, 22 hours of radio coverage, and print coverage by every paper in Idaho. The tour included several debates, and these clips are from two of them. Our folks creamed them! This one was so upset that he ran off the set while his mike was still plugged in, trailing studio equipment behind him. But we don't always have the opportunity to rebut them. They are making these statements all the time, everywhere they can. They have learned their trade well. They use the hearing process like A1 Hirt uses the trumpet. If the process of intervention should shut us down or prevent us from getting a license, so much to the good. But even if it doesn't - they win - for it causes delay - delay costs money and so does complying with regulation. If they can make us uneconomic, and that's not too hard to do these days, they have won. Regulation restricts the decision process. Any time the decision process IS restricted, you face the possible loss of a more economic alternative. They are out to pile every regulation on you they can and every delay they can. Initiatives! They came after us - the uranium industry - in South Dakota and Montana last year. They won in Montana. We tried to reverse it in the legislature, but they were too frightened of public reaction to do it. They did put it on the ballot for reversal in November of '82. That puts it squarely up to us to influence the public so we can win a campaign. There will be more initiatives, and at local levels as well as at state. We must join together and win! The public generally supports the continued operation of nuclear power plants. They about split on whether to build more. But they strongly support regulating the industry more stringently. Every survey reflects concern about safety and the desire for the government to take responsibility and regulate. You and I know that regulation nearly always adds cost, and only sometimes increases safety. We need to influence the creation of regulation. We need to accept responsible regulation and fight that which is counter-productive. To win in hearings, to win initiatives, to win in getting responsible regulation, we need public support. We need an informed, understanding, and supportive public. To accomplish this, we need two kinds of efforts. The first is to reach the people at the local level with local representatives of our industry. Informal conversations at church, PTA, cocktail parties, whatever. Presentations to Kiwanis Clubs, League of Women Voters, church groups - wherever we can. Facts, information in printed form, to these same local audiences with the credibility of the local sources. The second is to reach mass audiences through the media. Positive media. This can be done by advertising, but it is very expensive. We have to look to influencing the reporters and editors to get more balanced and accurate reporting. We need to get free time - interviews, debates, letters to the editors, etc. The Uranium Public Affairs Task Force was created last year to provide tools for you to use to reach these audiences (it is affiliated with the Atomic Industrial Forum). Twenty-two companies provided money and man- power. A consultant, Denver Research Group, was retained to produce materials. In this Phase I effort, we first researched what issues were of greatest concern and what were felt to be the greatest needs in materials. We determined that we did not have the funds to go out and do the job for the industry, so we decided to develop tools for the Industry to go out and do the job for itself. From the research, we determined what tools we should develop for you to use. We first developed a set of the quest- ions most likely to be asked of you and the issues most likely to be thrown up to you. We have developed a loose-leaf notebook. Each page contains one of those questions or issues, a short verbatim response that you can use, a short discussion of the subject, and references you can cite or research for further information. It is organized by subject: tailings, water radiation, etc. This book is an extremely handy tool for anyone in the industry. Each uranium location should have at least one.

E. V. Crane.*—I want to ask Dr. Goetzel concerning the control of atmosphere in heating and pressing. Was the heating and pressing done in the die, or were the two kept separate there? C. G. Goetzel.—The setup used for this investigation implied heating the die to the temperature at which the work was to proceed, introducing a preformed compact into the hot die. The atmosphere was supplied through an annular chamber from which it passed through two holes into the die cavity. E. V. CRane.—The compact was not preheated? C. G. Goetzel.—The compact was not preheated. Tee Chairman.—In the course of recent studies on the effect of time of heating upon the tensile strength and hardness, I have observed that there is often a maximum in tensile strength and hardness reached before complete homogenization has been attained. The magnitude of each mechanical Property changes rapidly with time in the early stages of sintering, the more so as temperature increases. For these reasons it seems that the comparison of values obtained by heating for the same time at a series of temperatures may be deceptive. Not only may those heated at higher temperatures give higher tensile readings, but the reverse may be true if the maximum in the tensile strength versus time curve has been passed. A better basis for comparison would be that of equal degree of diffusion. C' " Goetzel.—Thank you, Professor Rhines, for this interesting contribution. I would like to add here that I have noticed a similar effect with straight copper. There is, of course, the possibility that this maximum in hardness and tensile strength may be caused by work-hardening.

A GEOLOGIST --one versed in geology, the science which treats of the history of the earth and its life, especially as recorded in the rocks; that is Webster's definition. William Embry Wrather-one of the country's foremost geologists who heads the U. S. Geological Survey; this is the 1948 President of the Institute. He has studied the geology of areas on the face of the earth as far-flung as Texas and the Balkans, and now heads the world's largest staff of geologists. Vital statistics on Dr. Wrather would show his place of birth as Brandenburg, Ky., the year 1883. He will celebrate his threescore and five years of full living the twentieth of this month. As is usual in biographical sketches of this nature, the formative years of youth, and in many ways the most important years of one's life (since professional tendencies as well as many important personal decisions are evidenced before the teens are left behind) are passed over with the mere fact noted that a degree was earned at such and such educational institution. And so we note that Dr. Wrather received his Ph.B. degree at the University of Chicago in 1907, and followed up that degree with two years of graduate study.

The Commissioner of Education has issued a call for a public conference on business training for engineers and engineering training for students of business. This conference, national in scope and character fully representative of all interests, will be held in Washington, D. C. on June 23 and 24. Educational institutions, commercial organizations, and educational and engineering societies will be given an opportunity to state their views. Engineers, educators and business men will be invited to discuss the following major topics: Business Training for the Engineer; Engineering Training for Commercial Enterprises; Significance of the. War Experience for Engineering Education; Training of the Engineer for Foreign Projects. This conference has been called on behalf of the Conference Committee on Commercial Engineering. This Committee is composed of administrative professors in engineering and commerce from several of the large educational institutions and representatives from the American Institute of Mining and Metallurgical Engineers, Society for the Promotion of Engineering Education, The American Society of Civil Engineers, American Institute of Electrical Engineers, American Society .of Mechanical Engineers, and a committee f fifteen on Educational Preparation for Foreign Service.

When the suggestion was made by Major General Leonard Wood that the Institute assist in the formation of a National Reserve Corps of - Engineers, Dr. Drinker's name occurred first to the Board of Directors as the man who would be most capable of carrying out the proposed plan. Dr. Drinker has long been associated with work in connection with military training and is at present the Chairman of the Governing Committee on Military Training Camps Association which is having such important results at Plattsburg and other places in this country. As Chairman of the Institute's Committee on National Reserve Corps of Engineers, Dr. Drinker was a member of the Joint Conference Committee of the National Engineering Societies .on. this subject., He was an earnest worker in the movement, which, has finally resulted in definite legislation by Congress; whereby a Reserve Corps of Engineers is authorized in the new Army Bill which became effective July 1, 1916. Notice of the results of the work was sent to all the members of the National Engineering Societies early in July, and the and the Department of the United States has recently issued a circular which has been sent to all the members of the National Engineering: Societies, as well, as to many other engineers, outlining, the line, whereby engineers may enroll themselves in the Officers Reserve Corps. Dr. Drinker has, therefore, fulfilled the mission which he undertook when assuming the Chairmanship of the Institute's Committee. He now asks the permission of the Board of Directors to withdraw as Chairman and has requested that he be replaced in this position by Mr. Arthur S. Dwight, in; the belief that the Chairmanship of the Institute's Committee and, membership on the Joint Committee should be vested in a man ,located in New York City, for the better carrying put of the important work now before the Joint Committee. We are happy to say that Dr. Drinker has consented to remain a member of the Institute's Committee; but the completion of the first phase of his work; as,Chairman, should not be allowed, to pass without an expression of appreciation on behalf of the Institute for his services.

We might say that for the metallurgist time "ambles withal," for the mining engineer time "trots withal," and for the geologist, time "gallops withal." And anyone for whom time "stands still withal" does not belong in the mining community today! In this bicentennial year of the United States of America we sense the mystery of time and we feel the pulse of history, especially in our own profession. What was mining like 200 years ago? What is it like today? What will it be like 200 years in the future?

The Freeport Sulphur Co. built a portable crusher in 1944 that solved a problem that none of the crusher manufacturing companies contacted were able to do. Two of these crushers have now been in service for 6 years, giving satisfactory service in handling a million tons per year, and having a capacity of over 2000 long tons per 8-hr shift. These machines reduce ton size blocks of sulphur to 12 in. and also feed the conveyor system at the rate of 350 long tons per hr per machine.

Some statements have already been made to the Institute in reference to the cost of other departments of the above-named works, and some details have been given in tabular form.* For the purpose of the present paper it may be sufficient to say that this converting works is made up of three buildings, a cupolahouse, an engine-house, and a converting-house. The machinery and fixtures comprise two blowing-engines, two pressure-pumps, two five-ton converters, five hydraulic cranes, three pig-iron cupolas, four spiegel cupolas, two lifts for the cupolas, together with the usual arrangements of smaller parts. Every effort was made in the construction to combine efficiency of operation with durability, and the general course of the operation of the works during two and a half years seems to warrant the belief that the large outlay has been fully justified. * In the accompanying tabular statement all items on vouchers less than ten dollars, and all freight items have been omitted.

H. S. COE, St. Louis, MO. (written discussion *)-I feel much gratified that Mr. Mishler has confirmed those principles of slime settlement expressed by Mr. Clevenger and myself. I wish to state that, when we wrote the article referred to by. Mr. Mishler we had not seen his earlier article in which he gave a formula to be applied to the settling rate off feed pulp for determining thickener area required at El Tigre. It has been my experience that in cyanide work the settling area required is determined by the settling rate of the feed pulp for perhaps 20 per cent. of all of the ores to be encountered. For the other ores, the area required is greater than that indicated by the settling rate of the feed and corre-sponds to the settlement of a somewhat thicker free-settling pulp. Mr. Mishler, in his paper, has thoroughly outlined a set of tests for determining thickener capacity, which, if carefully carried out, should be entirely reliable, provided allowance is made for changes in the mill feed from time to time. Two features of his paper, I, believe; need comment. In speaking of the time required for slime to flocculate after being fed, Mr. Mishler quite properly states that the actual settling rate for the feed pulp can-not be that of completely flocculated pulp because of this time lost in flocculation. It seems to me, however, that this feature cannot be of very great importance, for the following reason: The upper zones of pulp in a thickener may be, and often are, as thin as the feed pulp. If, therefore, the feed be introduced at sufficient depth below the pulp surface to prevent agitation at the surface, there will be ample time for it to become flocculated before it becomes the surface layer, and it, will
