T HE 121st meeting of the Institute held in New York City, February 16 to 19, 1920, was a great success despite vicissitudes of weather of unusual severity. On account of tremendous snowstorms, only two members of the Canadian contingent arrived, and several of our members from the west arrived thirty hours late. Two weeks prior to the meeting, the heaviest snowstorm in 34 years wrecked the surface transportation in New York; and it was only by special dispensation that arrangements were effected, with the New York Street Cleaning Department to clear away 39th street in front of this building so that vehicles could reach the curb. The total registration of members and guests was 1138.

The urban environment presents special challenges for the design and construction of earth retention systems. Complications arising from difficult subsurface conditions are compounded by the presence of urban infrastructure and existing and prior construction. The proximity of adjacent structures as well as intense prior use can cause special concerns including the potential for archeological artifacts or contaminated ground or ground water. Utilities and structures may be particularly vulnerable to the effects of ground movement, dewatering and vibrations. Difficulty of access, congestion and limited work areas may severely restrict means and methods of construction. Dewatering may be limited or prohibited because of concerns for disposal of clean or contaminated water, depletion of aquifers, drawing of contaminants to the site or dewatering induced settlements.

M Y DUTIES, as a member of the Department of Franco-American War Cooperation of the French High Commission were to study the copper and brass industries of America from the mining of the various non-ferrous metals to the semi-finished, or finished materials. In the pursuit of these studies, it was my privilege to visit a number of industries and organizations in different parts of the country. I first visited most of the Eastern copper refineries that were supplying the Allies with vast amounts of metal. These works are producing their material by the multiple or the series process, although the first method predominates. But, regardless of the process employed all the plants attain an exceptionally high standard of quality in their production. One of the points that particularly attracted attention was the manner in which improvements could be traced from the older worlds to the more recent ones. The impression was that, thanks to a spirit of broad-minded cooperation between the principals of the companies and frequent exchanges of views between members of the staffs, all persons interested benefitted by the experience thus gained, to the advantage of the community at large.

It becomes my pleasant duty to call the meeting to order. This is our fiftieth regular meeting. And the session we are opening today, I am sure: will be as interesting and informative as those in the past. These gatherings present a fruitful opportunity for an exchange of experiences and ideas that will aid all of us in our work in the various segments within the coal industry. Walter Johnson and his Program Committee have arranged a wonderful program for us; Walter, due to his standing in the industry and his large acquaintanceship with the leaders of the industry, has really gone to town in bringing outstanding speakers and personalities to deliberate with us in our proceedings. A lot of things have happened since we last met; in the operating end, and in safety we have made marvellous headway, but we have slipped badly in the marketing end. However, I am sure the messages and discussion you will hear will point out ways and means of overcoming at least some of our difficulties. Before we get on with the program, I want to thank our hard working Secretary, Fred Whiteside, who, by the way, is a charter member of the Institute and has attended every one of the fifty meetings we have held; and the various committees who have been meeting for the past several months and who have arranged this fine program you are to hear. I hope all of you enjoy the convention; the business as well as the social sessions.

"It now becomes my privilege and duty to call to order this fifty-first meeting of the Rocky Mountain Coal Mining Institute. "I bid you a hearty welcome and I know by your attendance at these meetings you will gain a great deal of valuable information, as well as have a wonderful time. "We have been very ably represented by Mr. John H. Emrick as General Chairman, assisted by our good friend Mr. Fred W. Whiteside, our secretary and treasurer. I know they have worked very hard in selecting the various committees, who in turn - by the looks of our program have gone all out to prepare material that should be of great interest to us. I trust we will be attentive to the subjects presented and freely enter into the discussions, also relating our problems and experiences. I am sure this will prove both profitable and beneficial to all present. "The main purpose of these conventions is to become acquainted with each other, renew old acquaintances, talk over our problems, and have a little fun and relaxation from our every day routine. "Let us not forget the manufacturers, the distributors, the operators, or the press because it is through their splendid support that this organization is successful. "Since our last meeting we have gained many new members, whom we especially welcome. We are sorry to have lost a few. I am mindful, at this time, of two very good members from my home state who have passed away, Walter Wetzel, a former president of this institute, and Lee Alger, at the time of his death, Vice-President from Utah. We also lost very recently our assistant Secretary-Treasurer, Everret Davis. These men contributed a great deal to the institute and the coal industry in general. I am sure they are greatly missed by all who knew them."

"Guests and Members of the Rocky Mountain Coal Mining Institute: "It gives me a great deal of pleasure to call the Fifty-Second regular meeting to order this morning. "I think that you will agree with me that we have an excellent program planned for the next three days, comprising various interesting and educational subjects by authors of prominence, which will be of keen interest to all of us in the coal industry. "The Program Committee, chairmanned by John Peperakis, has done an excellent job in securing this very splendid talent for our convention. "I would like to say a word as to the, condition of the coal industry in our part of the country as well as elsewhere. I believe we can look at it with more optimism than in the past several years, particularly in the state of Colorado, with which I am more familiar. "Annual coal production in Colorado gradually dropped from around 12 million tons during the years of World War I to as low as 8 million tons during the last war, and to less than 3 million tons in the year of 1954. We believe that it touched bottom that year, as in 1955 the state production went up again to nearly 3,400,000 tons, equivalent to an increase of 15%. As you know, the national increase in bituminous coal production for the year of 1955 was roughly 2000 over 1954. "The national increase for the first two months of 1956 over the same period of 1955 is approximately 2100. Colorado's production is running around 1000 over the comparable period of last year, and the 5 states represented by our Institute came up with a nice increase in 1955 over 1954 of 1000. "Figures on the increase so, far in 1956 for this group of states are not readily available, but I fully believe that. our industry locally, as well as nationally, is now starting out on a steady rise despite the fanfare of nuclear energy and its more glamorous competitor, solar energy. Many authorities tell us that real competition from these sources is a long way off and that the atomic energy program will consume far more coal than is displaced by nuclear power. "I do not mean to infer that we coal people are out of the woods by a long way' so far as holding and regaining markets, for our coal. The captive operators, which are well represented here, have not lost their market for coking coal, since coke is still a necessary

Gentlemen: I'm glad to see the crowd that's here this morning, glad to renew acquaintances with many old friends, and if you'll look at the program you'll see a heading there which states that as President I have the honor and pleasure to be here to address the membership of this meeting of the Rocky Mountain Coal Mining Institute, this being the 49th regular meeting. The tentative schedule of this gathering lists on the program the "President's Address," and I want to assure you that this will not be an address or a lengthy speech. It's said that a good speaker is one who arises to the occasion and then promptly sits clown, so please be at ease for I intend to sit clown very soon. There are other men here who have spent time writing and preparing papers on subjects that are to come up for discussion at this meeting, which will be, I'm sure, more interesting than what I have to say this morning; so again I'll say, we'll get this part of the program under way promptly.

MR. MANLEY: Gentlemen, I have been asked to open this meeting in the absence of Mr. Shields. the President of the Rocky Mountain Coal Mining Institute, who is away on other business. We have here from him this morning a telegram addressed to the Secretary of the Institute, Mr. Whiteside. The telegram is from Mr. Shields; it reads: "IT IS WITH PLEASURE THAT THE COAL INDUSTRY OF UTAH WELCOMES THE INSTITUTE TO SALT LAKE CITY. WE APPRECIATE THE OPPORTUNITY OF -BEING YOUR HOST AND HOPE THAT YOU WILL ENJOY THE SPLENDID PROGRAM THAT HAS BEEN PRE¬PARED FOR YOU. IT IS WITH KEEN REGRET AND MUCH PERSONAL DISAPPOINTMENT THAT MATTERS OF GRAVE CONCERN TO THE INDUSTRY PREVENT ME FROM BEING PRESENT BUT I AM. SURE THAT UNDER THE ABLE DIRECTION OF THE OTHER OFFICERS AND MEMBERS THAT THE MEETING WILL PROCEED WITH CUSTOMARY DISPATCH. PLEASE MAY I TAKE THIS OPPORTUNITY TO EXPRESS MY GRATEFUL AC, KNOWLEDGMENT TO MRS. BUR, BIDGE AND TO MESSRS. MANLEY, CLARK,. PARMLEY, WEBBER, AND THEIR COMMITTEES WHO HAVE DEVOTED LONG HOURS IN ARRANGING YOUR PROGRAM. I EXTEND GREETINGS AND BEST' WISHES FOR A MOST SUCCESSFUL SESSION. "PAUL L. SHIELDS, "President." '

THIS meeting was held in the new home of the Institute, the United Engineering Society Building, 29 West 39th Street, New York City, directly following the Dedication ceremonies. The first session was held in the large Auditorium, Thursday, April 18. The meeting was called to order by Mr. John Hays Hammond, President of the Council, who said Before taking up the reading and discussion of papers, I will call upon Dr. Rossiter W. Raymond, the oldest living past-President of the Institute, who has been in harness almost continuously for thirty-six years, and who has contributed more than any one else to bring this society to its present great success and to establish the reputation of the American mining engineer the world over, for a few words supplementary to those which were uttered to engineers generally, during the sessions of yesterday and the day before. ADDRESS BY R. W. RAYMOND. The generally accepted Darwinian doctrine of the survival of the fittest is sometimes illustrated by persons who are supposed to be the fittest because they have simply survived. I fear that I come under that category. Almost all of my contemporaries in the early history of this Institute have passed away. Only one or two of the original founders remain, and I may fairly say that scarcely any remain who were active at that : time in shaping the organization and the future career of the Institute. In May, 1871, I was thirty-one years old. Next week I shall be sixty-seven years old. All the intervening years have been devoted to the service of this Institute almost continuously, either as President or Vice-President or Secretary. You may easily imagine, therefore, with what pleasure I greet you on this occasion. I am not here to extend to you the welcome of the City - of
