A full account of the wonderful Arizona meeting will be published in the December Bulletin. For the strenuous, interesting, and altogether happy week, we express our hearty thanks to those marvels of energy and thoughtfulness, the members of the local committees in Texas, New Mexico and Arizona. In this number we publish the discussion resulting from the technical session on "Flotation." Because of the timeliness of the subject, this session's discussion was transcribed first and sent to the contributors, and, thanks to their promptness in revising, we are able to print it in this issue.

Birmingham - A City With a Future COURTING new industries is the time honored duty of the chambers of commerce; but Birmingham, until recently, has done its courting without the benefit of troubadors. This is all changed now for the iron and steel industry is singing an enticing song about steel priorities for new industries from Birmingham's own mills. Along with the increasing industrialization of Birmingham there has been a marked influx of industry into the Southeast and neighboring areas in the south central states which augurs well for business in Birmingham. This important stronghold of the foundry industry (consuming 95 pct of Birmingham's merchant pig iron in 1950) has been the source of important announcements about additions to steel ingot capacity. The virtual abolition of basing point pricing gives the Birmingham iron and steel industry an advantage in the South's new markets. This means more business for Birmingham, but the problem of raw materials supplies is posed.

Joseph G. Butler, Jr., who represented this Institute on the American Industrial Commission to France, has presented a report to the Chairman of the Commission regarding the steel industry of France in war time. In this report Mr. Butler calls attention to the fact that only a few steel works were visited and that he thinks it probable that there are many plants in France more up-to-date than these. He noticed especially in the plants visited a dearth of labor-saving devices and not very great attention to the safety of the employees. He also noticed that the whole of the iron and steel interests in France are being used at the present time by the Government for war purposes, and he was told on good authority that the production has doubled since May, 1915. When the war is over, it is thought that France can send large quantities of iron ore from Algeria to the United States and take in return American coal to France, an interchange which would doubtless be of mutual advantage. In Mr. Butler's opinion the shortage of coal in France may be overcome to some extent by the use of water-power and by electrical processes for steel manufacture, and lie believes when the war ends France will be able to compete with other countries in exports of general iron and steel products, this trade being facilitated by the port improvements at Bordeaux and Marseilles. The French labor situation is much better than that in the United States from the standpoint of labor unions, but the wages are less and many women are now being employed to do men's work. This has a tendency to keep wages low, but is probably a war expedient only. The cooperation among manufacturers in France is at a high level and both local and national organizations exist for the discussion and voicing of trade problems. The national body which is a combination of the individual organizations is the Comite des Forges de France and it is an interesting fact that many of the members of this body are office holders under the Government, or heads of Government Committees which are organized to look after the very business in, which the individuals are engaged.

The Engineering Council met on October 11 in the rooms of the American Society of Mechanical Engineers, Engineering Societies Building, New York. The Rules Committee submitted a draft of rules for the admission of other societies to the Council and progress was made in their consideration. The Committee on Public Affairs reported on a number of requests that the Council support pending or proposed legislation. Remedial laws intended to promote hydro-electric development were favored and Council voted to offer its cooperation to the United States Chamber of Commerce which is interesting itself in this matter. A movement to coordinate, unify and strengthen the work of various engineering committees cooperating with the federal authorities at Washington was favorably considered. Messrs. H. W. Buck and Charles. Whiting Baker were appointed Council conferees. CALVERT TOWNLEY, Secretary.

EDUCATION is a business; and, if the consumer is satisfied with the product, no one has any grounds for complaint. "Pretty well satisfied" about slims up the attitude of the mining industry toward the young graduates presently entering the field. Yet, with amazing regularity the controversy over the five-year curriculum recurs in educational circles. The educational mills grind out their products, some higher grade than others, depending on individual proclivity. The cycle continues almost without interruption. Arthur Taggart, however, takes his bowie knife to some of the sturdiest limbs of the tree of knowledge in his article on engineering education on page 770 of this issue. As all who know him might suspect, the pruning is not restrained. With one swing of the knife, such practically-labeled courses as Mine Design are stricken from the tree and transplanted to the field of Graduate Education. Emphasis on the basic sciences and the study of man through courses in history, economics, and literature are recommended to constitute an undergraduate curriculum. Such courses show the least depreciation and therefore give the student the most for his money. Partial justification for this dramatic departure from tradition is explained by the increasing number of companies giving training courses. Why make the student pay for what he can get paid for learning after graduation, the author argues. Other leading educators espouse this doctrine. Dean S. C. Hollister of Cornell, for the Committee on Adequacy and Standards of Engineering Education, recommended to ECPD in 1951 that emphasis be placed on the basic sciences. "Sifting back through the curriculum, it seems clear that instruction in the basic sciences, if taught in a manner such that knowledge of them makes available working tools, contributes the most sustaining part of the curriculum", reported the committee. Note that he would utilize practical problems from the fields of engineering in teaching the sciences. In our opinion the important thing to learn in college is how to think the engineering approach. Recitation on traditional solutions of classic problems sharpens the memory, not the ingenuity of the student. The engineering schools of the nation recognize the advantage of great emphasis on fundamentals, and the inclusion of cultural courses in the curriculum. However, industry presently requires graduates to have a substantial knowledge of the tools of the trade upon graduation. This means that the colleges are forced to pare to the bone to encompass the required studies in the time allotted. In addition, there is the limitation of student money. College educators also claim that entering freshmen are often improperly prepared in such subjects as writing and mathematics. These considerations make it difficult for the critic of the engineering graduate to make any headway with the educators. Actually with the mounting problems imposed by lower grade and more complex ores, a new breed of engineers is needed. The impetus for this new product must come from industry. If there was a concerted effort from industry for an improved type of engineer, the colleges would modify their aims to meet the demand for the kind of individual desired.

In most mineral enterprises, what is the progress, and shift in responsibilities, as the young engineer advances in the corporation? You are all familiar with the normal pattern-in mine production from level boss, to shift boss, to superintendent to manager; in milling from test engineer, to shift boss, to foreman, to superintendent and then manager; in engineering from surveying on to Chief Engineer; and all then aspire to the corporation presidency. Note the shift-from purely technical jobs, say in the first five to ten years in the profession, to administrative positions for 30 to 40 years. What is the average preparation given to mineral engineering students, who can look forward to about 30 years of administrative work? From the catalogs of 21 institutions, offering 36 curricula of four years length, in mining and/or metallurgy, requiring the equivalent of about 150 to 160 semesterhours for graduation, the following results were obtained: Average number of semester hours of economics, 3 hr. Range of requirements, 0 to 8 hr. Thirteen curricula do not require any economics. Accounting and business law, average: 1 semester hr, 26 curricula do not require business law or accounting.

PERHAPS, back in the early eighties, the fates were advised that the world had need of a determined man, yet one who could always inspire teamwork; at any rate on Dec. 20, 1881, Louis Shattuck Cates was born to Edwin Wallace and Emily Allen (Johnson) Cates, in Boston. To his friends he has always seemed a little more determined than anyone else they knew-yet his capacity for organization and enlisting friendly co-operation from all with whom he became associated has perhaps been his greatest asset. His will and imagination set the goal, but his friendliness and qualities of leadership brought results. He was born just nine years after the great Morenci mine was opened by Robert Metcalf and his associates. Educated in the public schools of Boston, Mr. Cates was graduated from Boston High School, and since at that time Boston was headquarters for many of the great mining enterprises and promotions in the country, he chose Massachusetts Institute of Technology as the college which would best prepare him to succeed in the mining industry. He was granted a Degree of S.B. from "Tech" in 1902, but already his getting-along-with-people talent had won him honors. He was class president in his junior year, and "First Marshal" at graduation.

THE four different modes, more or less practiced for subdividing slag (that is, producing slag sand), are the following : 1. Crushing the slag from the lump in Blake's crusher, by edge runners or other suitable means. 2. Blowing water, steam, cold or hot air, into the stream of viscous slag whilst it runs from the furnace. So treated, the slag takes
