OUR 78th Annual Meeting was, technically and attendance-wise, one of the greatest to date. No one who came to New York's Hotel Statler had time to hear all 266 papers, or to attend all 70 sessions and 27 committee meetings, or to shake the hands of the more than 3000 engineers, educators, students and executives who attended-but no one was lost in the crowd. For crowds always dwindle down to groups of two and three and four, and those are the little sessions which make our meetings well worth attending. Herewith four pages of photographic highlights and sidelights on the February gathering.

RECORDING that the latest annual meeting was the largest and most successful ever held has be-come almost a habit, but when, as this year, the registration on the first day exceeded any other first day by two hundred, the annual dinner attracted nearly 1200, as compared with 750 at the previous largest one, and the number of technical sessions was larger than ever before, there seems no escape from so regarding it. In spite of the third day being a legal holiday (Washington's Birthday) no slackening, in attendance and interest was noted, and throughout the four days the greatest problem was to find enough meeting rooms and chairs to provide for the sessions, of which as many as twelve were in progress at one time. Solution of the problem would not have been possible (since the Engi-neering Societies building, was designed to provide only three general meeting rooms) except that a part of the eighth floor happened to be temporarily vacant. As these extra rooms will not be available next year, it may become necessary to adopt measures to keep the annual meeting down to the limit of facilities for handling it. The meeting opened on Monday with simultaneous sessions on iron and steel, geophysical prospecting, mine ventilation, non-metallic minerals, and milling, methods. The first four, which were continued after the usual recess for lunch, are reported in more detail elsewhere.

A LARGE attendance at the annual dinner of the Institute, to be held this year on Tuesday eve-ning of convention week, is already assured. Presentation of the Douglas, Hunt and Saunders medals will attract unusual attention since not only in Blaylock, Mathews and Hoover the Institute will be honoring men who have made notable contributions to the advance-ment of their profession, but as to one of them each person as he passes down the reception line will be won-dering whether in renewing acquaintance with our past-president and present Secretary of Commerce, he is not greeting the next president of the United States. Elsewhere in this issue accounts of the professional careers of these three men appear as also of the two younger men, Charles H. Herty, Jr., and P. H. Royster, who are to receive the Robert W. Hunt and the J. E. Johnson awards. Institute honors go for technical achievement, but the Institute will be proud and happy if the nation should later confirm its own judgment by placing larger responsibilities on one of its members. The medals are to be presented at the annual dinner following the President's reception and preceding the dance. There will be no. other speeches and since the occasion falls on Carnival Night a particularly gay evening is anticipated. The event will be at the Wal-dorf as usual, and members are urged to return prompt-ly the reservation cards sent them by mail. Other entertainment features will include a Smoker, Monday evening at 8.15, held at Mecca Temple and in charge of a new committee with Fred Kay of the Petro-leum Division as chairman. He promises that vocal music will not be allowed to interrupt conversation. Lunch will be served each day on the Fifth Floor of the Engineering Societies Building, and ten special luncheons and dinners have been arranged for particu-lar committees and groups as shown by the detailed program. The Woman's Auxiliary has laid out a gen-erous program including luncheons, teas, a theater party on the night the men folks go to the Smoker, visits to museums and, not the least important, a round of the leading shops. The Excursion Committee is arranging for an excur-sion sure to be of interest. The American Smelting and Refining Co. has opened its great Perth Amboy plant to the Institute, and on Thursday, Feb. 23, a party will be taken to it by bus traveling through the Holland Tunnel en route. Full opportunity will be afforded those interested to see the workings of the ventilation system of that great public work. If a sufficient number indicate interest, arrangements will be made for group excursions to other plants in the vicinity of the city.

THE twenty-second annual meeting of the Canadian Mining Institute was held at the King Edward Hotel, Toronto, on Mar. 8, 9, and 10, and was followed on the 11th by an all-day excursion to the International Nickel Refinery at Port Colborne. The meeting was very well attended and dealt with some of the most important matters, both technical and economic, that have ever come before the Canadian Institute. The question of licensing engineers is before the Canadian members as it is before our own in this country and the attitude of the mining engineers across the border is like that of the American mining engineers, opposed to the licensing of the mining. engineer, however they may feel toward the licensing of other branches of the engineering profession. It was well pointed out that such a law, had it been in existence in the last decade or two, would probably have prevented the rapid development of Canada's mines. Whereas one civil engineer can run a line of survey as well as another, perhaps, it is only a question in his case of whether he can or cannot survey. In the case of a mining engineer employed by a man with capital to invest in a development project, unless the man with the money has confidence in the judgment of his engineer the fact that he is a professional man would carry little weight in inducing a large investment toward the development of Canada's resources. It was also pointed out that although the Institute as a whole had not passed on the matter, it would probably be opposed to legislation aiming only for self-interest, but would be heartily in accord with legislation which could be shown to be for the service of the community at large.

The annual meeting of the Woman's Auxiliary was held on February 19, at 10 a. m. The president, Mrs. Sidney Jennings, said in her greeting "it is a matter of congratulation that during the past year when the demands upon women for work of all kinds has been so large our membership has grown from the 50 enrolled at the first meeting a year ago to over 300 today. Some women, when. asked to join the organization, say that they are doing so much work in other ways that they have no time for work in a new organization, but the director for Canada struck the right note in her report when she told us of the splendid work the wives of mining engineers are doing in Canada, as individuals and as leaders and members of various organizations doing patriotic work. We do not want to divert such women from the work they are now doing, but we do want them to enroll as members of the Woman's Auxiliary and let us know what they are doing, that they play give inspiration to others." Reports were made by the directors of the following sections: Canada, Chicago, Colorado, Columbia, New York, Puget Sound and St. Louis, in some of which sections excellent progress has been made in food conservation, foreign war relief, including the adoption of fatherless French children, and in work for our own engineering regiments. These reports were read, accepted, and placed on file. The reports of the corresponding secretary, of the recording secretary, and of the treasurer, were read, accepted, and placed on file. Various amendments to the Constitution were proposed and accepted, and copies of the Constitution, as amended, will be mailed to all the members of the Woman's Auxiliary.

THE most successful and largest meeting of the Auxiliary to the A. I. M. E. was held this year. Great praise is due Mrs. Arthur S. Dwight, the acting chairman of the Ladies' Committee in the ab-sence of Mrs. Barron, and the other members of her committee for the able way in which they planned and carried out a varied and interesting program. Miss Margaret Callow, chairman of the Junior Committee, with her co-workers, made the days delightful for the Junior members, as well as visiting daughters. Under the leadership of Mrs. Jenkins, the registration of the ladies proceeded smoothly Monday morning. At the Mrs. Jenkins became ill with pneumonia on the second day of the meeting and was taken from the dinner to a hospital where she died the following Sunday. Born in Kansas City fifty years ago, she was an active and valued member of the Auxiliary in which she had long represented the Puget Sound Section. Mr. and Mrs. Jenkins, the latter treasurer of the Utah Consolidated Copper Co., had previously lived at McGill, Nev., where they are well known. She leaves a son and a daughter. luncheon on the fifth floor, Mrs. DeGolyer and Mrs. Church arranged a delightful hour, when greeting visit-ing friends proved more. interesting than food. Mrs. Bain efficiently ushered the ladies through the after-noon's program, seeing that they all found the buses on time. The first stop was at the Cloisters, where the quaint carvings and the faint odor of incense trans-ported all the visitors to the Middle Ages. That atmos-phere still clung, as we all looked at the marvelous collection of old Chinese jade, at the Metropolitan Museum, which was the next stop. The buses then took us to the MacDowell Club, where Mrs. Dwight gave a charming welcome, in the absence of the hostess, Mrs. Barron. The program, by Mr. and Mrs. Hardesty John¬son, was such a delight that repeated calls induced the artists to graciously respond with an encore. Then Mrs. Coster and Mrs. Sharpless assisted Mrs. Dwight in serving tea, about the glowing fireplace. In the evening the theater-goers guided by Mrs. Jordan were thrilled by "Interference.:" A detailed account of the annual meeting, in many ways the most interesting the Auxiliary has had, will be published later. This held the attention. of the mem-bers both morning and afternoon, on Tuesday. The absence of the President, Mrs. Barron, was much re-gretted, and the letter and the cablegram with her cor-dial greetings were much appreciated. Miss Stone ably presided in the place of Mrs. Barron, and graciously welcomed the incoming President, Mrs. Hoover. Her well-worded speech, accepting the office, was received with much enthusiasm. The visiting members were especially pleased with her description of herself as a "peripatetic-president." promising to visit the various sections as she crossed the continent on her frequent trips to California. An inspiring report was read from each section, and most particularly pleasing was a greet-ing brought by Mrs. Bateman of Toronto, from our sister organization in Canada. The sections are surely to be congratulated on their splendid work, not only for their own members, but also in sending clothing and other aids to the needy, as Mrs. Reynders directed, and in supporting libraries under the leadership of Mrs. Huntoon. The important work of the Educational Com-mittee, with its presentation of scholarships to various deserving young men, has been most efficiently carried on by Mrs. Jennings. Mrs. Jordan has inspired many to help in Braille, and Mrs. Eilers has extended the hos-pitality of the Auxiliary to many. The Washington Section is leading a movement to extend the privileges of Girl Scouting to the girls in lonely mining camps. The officers of the past year received flowers and grate-ful appreciation, and the incoming officers received a warm welcome. Very delightful features of the after-noon were the speech by the President of the A. I. M. E. for the coming year, Dr. George Otis Smith, and when a visiting member rose to say how much all the visiting members had enjoyed the Auxiliary's hospitality. The banquet and dance at the Waldorf were the most brilliant the Auxiliary has attended. Nearly twelve hundred were there to enjoy the festivity and to hear the speeches given, as Mr. Hoover and the other re-cipients accepted their medals and awards. The young people, the future supporters of the A. I. M. E. and the Auxiliary, enjoyed more hilarious tables in the bal-conies, and all enjoyed the dancing later.

IF the observation of our British friends is true that Americans put new records in bigness above everything else then the 150th meeting of the Institute was not the grand success it seemed to be. Just why the attendance slumped a little this year is anyone's guess, but the favourite explanation seemed to be that half the country is planning to come to the New York World's Fair this summer and that two trips from the hinterland to the me- tropolis, with another to San Francisco of course, can hardly be justified with the present condition of the stock market and the prices of the products of our mines. Certainly, some were pre- vented from coming too by the epidemic of respiratory afflictions that was rampant in February. Unfortunately. several succumbed after they had reached New York.

May 219t, 1872. THE Institute assembled in the rooms of the Geographical Society at the Cooper Union, Tuesday evening at 8 P.M. President Raymond called the meeting to order, and introduced Mr. Abram S. Hewitt, who welcomed the Institute to New York. President Raymond, in behalf of the Institute, replied. The President then read the following report of the Council for the past year. The Council respectfully report that the American Institute of Mining Engineers has held four meetings-at Wilkes-Barre, Bethlehem, Troy, and Philadelphia, respectively-all of which have been well attended, and socially and professionally most successful. The proceedings of these meetings having been published in the Engineering and Mining Journal, and sent to all members and associates, are sufficiently well known. Forty-four papers, by twenty-six authors, have been read. These papers embrace s wide range of subjects, and prove the practical character of the proceedings of the Institute. The finances are in a satisfactory condition. By the report of the Treasurer it appears that $1290.10 have been received, $519.90 expended, and that $770.20 now remains in the treasury exclusive of fees for 1872. This fund, it is hoped, will be so increased by voluntary subscriptions as to enable us before long to issue s volume of our most important transactions in a permanent form. The Council has made a favorable arrangement with the Scientific Publishing Company, publishing the Engineering and Mining Journal, by which that journal became the organ of the Institute for the first publication of the proceedings, papers, and notices to members. This arrangement it is proposed to continue through the present year unless the Institute shall otherwise direct. It is not intended to supersede the publication of an annual or occasional volume, but to maintain an interest in the Institute, and to serve the convenience of members while our funds do not permit s more ambitious publication.

THE opening session was held on Tuesday evening, February 17th, in the house of the American Society of Civil Engineers. The President of the Institute, Mr. E. B. Coxe, after a few introductory remarks, congratulating the members on the general prosperity in all the branches of the professions and manufactures represented by the Institute, called on Mr. E. F. Loiseau, of Philadelphia, for the first paper, On the Successful Manufacture of Compressed Fuel at Port Richmond, Philadelphia. Professor Prime called attention to the fact that the work of the United States Testing Board had been left unfinished at a point when valuable results had just been reached, and offered the following resolutions: WHEREAS, The American Institute of Mining Engineers has seen with regret that the work of the United States Testing Board has been suspended through the lack of an appropriation by Congress, which appropriation dues not seem likely to be renewed, and WHEREAS, It seems most important to the vital interests of our iron and steel manufactures that the experiments commenced by the United States Testing Board should be carried to successful completion ; Resolved, That a committee of three be appointed, to act with a like, committee to he appointed by the American Society of Civil Engineers, to carry out to completion the work commenced by the United States Testing Board. Resolved, That the American Society of Civil Engineers be requested to cooperate with this society by the appointment of a like committee. Resolved, That the committee have authority to request, in the name of the American Institute of Mining Engineers, contributions to a fund to be devoted to the completion of the experiments aforesaid. Resolved, That the Council of this Institute be authorized, whenever requested by the committee so appointed, to petition Congress for the free use of the testing machine at the United States Arsenal at Watertown. Resolved, That a committee be appointed by the President, to select the afore-said committee of experts. Resolved, That the President of the Institute have authority to fill any vacancies which may occur in the committee. The resolutions were unanimously adopted, and President Coxe appointed the following committee in accordance with the resolutions : Messrs. A. L. Holley, James Park, Jr., and J. F. Holloway. The President also appointed Messrs. Heinrich, Mickley, and Spils-

LOCAL COMMITTEE OF ARRANGEMENTS. Major J. W. Powell, Chairman; F. P. Dewey. Secretary; S. F. Emmons, A. S. Hewitt, J. P- Hilgard, Charles Knap, and F. W. Taylor. THE opening session was held in the hall of the new National Museum, on Tuesday evening, February 21st. President Metcalf introduced General W. T. Sherman, one of the Regents of the Smithsonian Institution, who read the following address: ADDRESS OF GENERAL SHERMAN. MR. PRESIDENT AND GENTLEMEN : I have been invited to meet you here this evening to extend to you the cordial greeting of the regents of the Smithsonian Institution, and to assure you that they are most happy to have it in their power to place at your disposal this beautiful hall, dedicated to science and art. This National Museum is the property of the United States, of which the regents of the Smithsonian are simply the custodians, and the board has delegated to its secretary, Professor Baird, the right to extend its use to the National Academy of Sciences and like kindred societies, among which we are glad to class the Institute of Mining Engineers. It is eminently fit that you should meet here at this, the nation's capital, under a roof partly your own, devoted to natural sciences, and in the shadow of the Smithsonian, founded for the exclusive purpose of collecting and diffusing knowledge among men. Of all the workers employed on earth no single class seem to me more worthy the respect of their fellows than those who seek beneath the surface for the useful minerals and metals which contribute so largely to the wealth and comfort of mankind. In no branch of human industry does intelligence come so immediately in contact with labor. To the mining engineer chemistry, mineralogy, and geology are as reading, writing, and arithmetic to the merchant;

THE Institute assembled in the Court-House, on Tuesday evening, May 22d, and was called to order by Vice-President E. B. Coxe. After announcement by the Local Committee of the programme for excursions, the Secretary read the following annual report of the Council The Council, in presenting to the Institute its annual report, has to record a most eventful year in the history of the Institute. Three meetings, as usual, have been held, two in Philadelphia and one in New York. At the Philadelphia meetings in June and October, there were present many distinguished foreign engineers, some of whom contributed communications to the Institute, and took part in its discussions. Sixty-seven papers have, in all, been presented to the Institute, which will be published in the fifth volume of Transactions. There has been an accession to the membership of 1 honorary member, 11 foreign members, and 162 members and associates; -8 have resigned, 6 have died, and 30 have been dropped from the roll, after due notification, for non-payment of dues. The membership now comprises 5 honorary members, 60 foreign members, and 644 members and associates, in all 699. As worthy of especial mention in the work of the year are the Discussions on Technical Education in connection with the American Society of Civil Engineers, and the report of the-International Committee appointed by the Institute to consider the nomenclature of iron and steel. The Discussions on Technical Education have been published in a separate volume, and comprise a valuable and suggestive collection of the views of practical engineers and educators. The report of the International Committee, composed of Messrs. Akerman, of Sweden; Bell, of England; Tunner, of Austria; Gruner, of France; Wedding, of Prussia; and Holley and Egleston, of the United States, has received the careful attention of engineers and metallurgists of all countries, and has met . with very general acceptance. Of the work of the Centennial Committee in Philadelphia the members are generally familiar, from personal experience, and from the detailed report of the committee at the last meeting of the Institute. But the record of the service rendered by this committee would he incomplete without mention of the numerous letters of thanks and formal expressions of obligations received by the Institute from individuals, societies, and governments abroad. The wise and generous spirit in which the work of the committee was planned, and the laborious and self-sacrificing manner in which it was carried out, call for emphatic expressions of thanks from the Institute. The gifts of Centennial exhibits to the Institute, largely as testimonials for services rendered, has necessitated the appointment of a Museum Committee for

THE stage is set for the 1930 Annual Meeting. It will take place in the Engineering Societies Building. Feb. 17, 18, 19 and 20, and an unusual pro- gram of technical papers, symposia, lectures and addresses, interspersed with luncheons, dinners, excursions and worthwhile entertainment for the four days has been arranged. The curtain rises on Monday morning and the first act is by the entire company-registration. Then the meeting hits its stride, for there are ten technical sessions on Monday, and the range of subjects includes most of the Institute membership. The Committee on Coal and Coal Products, which is about to become the Coal Division, presents a symposium of a dozen or more papers on Coal Classification, concluding its afternoon session with several papers on general subjects. At its luncheon between sessions, C. E. Bockus, president of the National Coal Association, will be the honored guest. Papers of theoretical character will be discussed at the morning session of the Committee on Geophysical Prospecting; at its afternoon session there will be presented summaries of results obtained at various properties by methods described at previous meetings of this group and permanently recorded in "Geophysical Prospecting," published by the Institute early in 1929. Members of the Petroleum Division should not overlook the paper by Theodor Zuschlag, on this Committee's program. It is entitled, "Oil Structure Mapping by the Sundberg Method." Members of the Iron and Steel and Institute of Metals divisions will find it profitable to attend the session on Engineering Education on Monday afternoon. E. A. Holbrook has arranged a program of ten-minute talks on Metallurgical Education which are designed to get down to "brass tacks." and the practical man may, in discussion, contribute as well as learn. At 5 p. m. Thomas T. Read will lecture+ at Columbia University, on "Recent Progress in Economics of the Mineral Industries."

The annual mine planning process is one of the most important tactical/operational steps towards achieving strategic goals. These tactical plans are part of a very comprehensive Mineral Resource Management process, with the natural sequel to planning being execution. The execution of an underground hard rock mine plan is a multi-project environment that comprises many development-construction-equipping-stoping single project paths, which are referred to as ?stoping paths?. The uncertainty that typifies execution of projects comes in the form of untimely disruptions to constituent tasks and/or project paths. Annual mining plans also include quantified objectives for occupational health and safety, production, quality, cost, employee morale, environment, and corporate social investment. Such objectives make for a highly complex environment that management must contend with?complex in the sense that all the paths and objectives have interdependent constraints. Furthermore, at the time of this paper, Sections54*and 55**of the MHSA*** put the onus on management to ensure legislative adherence. It stands to reason that planning estimates allow excess capacity?buffers?that cushions the impact of untimely disruptions. This paper concerns the fact that despite all the buffers allowed for, time, scope, and budget creeps impact on mine planning and threaten its successful execution. As a consequence, the paper deals with buffer management, the essence of Critical Chain Project Management (CCPM). Effective buffer management provided strategic (executive level) updates without losing the tactical/operational detail necessary for job card creation, especially where professional skills and experience are in short supply. Indicative bottom-line results showed CCPM to be highly effective.
