Mr. Shepard's paper was unfortunately delivered extemperaneously so no record is at hand. He spoke most interestingly and at length on the oil shales of Colorado, giving his opinion as to the ultimate outcome of the oil shale industry. He explained his idea that it would be built up of comparatively small plants, each of which would make the crudes, or more exactly would roughly divide the crude into its fractions, piping or shipping the fractions to a Central Refinery, using the residue for fertilizer, as it runs very high in fertilizer salts. He recommended that this plan be taken up by Coal Producers, that they consider the possibility of breaking up coal and selling its more refined products in place of selling raw coal. He spoke at length of the various outlets for products of distillation. Mr. McDermott gave a very interesting talk later on work that is being done in the Northern Colorado field along these lines. Mr. McDermott mentioned the strange fact that coaly materials such as mother of coal appeared to give just as good or better results under distillation than did lignite coal. Messrs. Randall, Howe, Goddard, Danford, and Nash added interesting data covering the use of pulverized fuel, and this data will be collected and offered to the Institute later in the form of a paper. Mr. Young spoke of the use of powdered coal in small units for small plants, mentioning the system now being offered by an Eastern Iron Works for small heating plants.

Our next speaker this afternoon is a good friend of mine of some years. I must introduce him by way of a little story. Now Harris Sherman, many of you know because he was really in charge of everything to do with the mining industry in the State of Colorado for a good many years. Some of you may know that before he became part of Governor, Lamm's first cabinet as Director of Department of Natural Resources, he was an attorney for the Environmental Defense Fund and that caused me considerable panic as I think it might have caused some of you. I have observed Hams from the time he stepped into that office until he retired from that office to go into private practice as the senior partner of Arnold & Porter's Denver office, one of the , nation's most prestigious law firms. Hams is a Colorado native. He's lived here all of his life. He's a graduate of Columbia Law School for his law degree and a graduate of Colorado College down at the Springs for his BA. He has served in state government, but I thought it might be appropriate, since he is no longer in state government, if we used Harris, today, to tell us from a former state official's perspective what the image is of the coal industry from the seat he held in Governor Lamm's cabinet for a good many years. He has been the recipient of a number of honors that I think you should know about including Phi Beta Kappa and

The Sixtieth Regular Meeting of the Rocky Mountain Coal Mining Institute convening at the Stanley Hotel in Estes Park, Colorado, was declared in session at 10:10 a.m. by Past President Mike Zakotnik, Jr., General Superintendent, The Kemmerer Coal Company, Frontier, Wyoming. Mike introduced Claude P. Heiner, President, Minerals and Development Corporation, Salt Lake City, Utah; and President of the Rocky Mountain Coal Mining Institute. President's Address Members of the Rocky Mountain Coal Min- ing Institute, guests, visitors and friends: I feel this is a distinct honor to talk to you on the occasion of this 60th regular meeting of the Institute. I once assumed this would be the Institute's 60th birthday, but later found that the first meeting was held in the State Capitol at Denver on November 12, 1912, at which time a comparatively small group of operators duly organized the Institute; a Mr. Weitzel of Colorado Fuel & Iron Company was then elected president and our late and dearly remembered Fred W. Whiteside, whose wife Gussie now carries Fred's work forward, was elected secretary. From Fred's records, early meetings were held semi-annually at rather irregular intervals, so that this 60th meeting is approximately the 52nd birthday of the organization and I am number 44 to serve as president. This latter development, I am sure, was conjured up last year by certain members at Glenwood Springs when I was absent. Anyway, I am honored and trust 'that these sessions will be both interesting and instructive in helping us on our way in the coal business.

The Thirty-sixth, Regular Meeting of the Rocky Mountain Coal Mining Institute was called to order at the Shirley-Savoy Hotel, Denver, Colorado, Thursday, June 23, 1938, at 11:15 o'clock a.m., by Thomas Allen, Vice-President for Colorado, who announced that owing to the serious illness of Fritz Nyman's father, Mr. Nyman would be unable to attend the convention. Vice-President Allen welcomed the convention as a representative of Governor Ammons. Owing to the overlapping of a previous engagement, Mayor Benjamin F. Stapleton regretfully arrived too late to welcome the gathering in behalf of the City of Denver. Vice-President Allen selected Mr. F. W. Whiteside to preside at the morning session. On motion made, seconded and carried, the reading of the minutes of the Thirty-fifth Regular Meeting was dispensed with, inasmuch as they are printed in the proceedings. Chairman Whiteside suggested that the appointment of the personnel for the Committee on Resolutions, Nominating, Membership and Auditing be deferred until later in the meeting, and on motion made by Mr. Oliver, duly seconded and carried, this suggestion was adopted.

The question of disposition of the slack and dust so troublesome to coal mine operators of the West has been divided by your committee chairman into three heads, viz: The preparation and transportation of fine and powdered coal. The developments along the line of low heat carbonization. The uses to which fine and pulverized coal have been put. The development of low heat carbonization has been assigned to me. This is really not a part of the subject but as it has a most important bearing on the future use of coal, I presume the chairman thought best to include it. An English committee on smoke abatement makes the statement that the burning of raw coal is "dirty, wasteful and unscientific". I will go a step further and characterize it as an "economic crime." It has been predicted by eminent scientific men that eventually no raw coal will be burned for heat or power purposes. All this will take time, experimentation and large expenditure, but it will surely come. The question of disposition of slack and dust so troublesome to coal and utilization of its by-products has been retarded by the abundance and cheapness of the raw coal, and by the abundance of suitable coking coals for metallurgical purposes. But necessity is surely, if slowly, demanding that the enormous waste ensuing from the burning of raw coal for heat and power must cease. For instance, smoke abatement investigations in Manchester, England, showed that the increased cost of household washing was about $1,250,000 per year due to smoke and soot. It is estimated that in London 200 tons of soot and smoke particles are suspended in the atmosphere over that city during dense fogs and that much more than this is emitted from the chimneys each winter day during the forenoon. As an example of what benefits a smokeless fuel gives, it is cited that in the mill town of Shaw, England, the burning of smokeless fuels in the factories has reduced the so-called fogs by about 80%. Necessity, caused by the war led Germany into the field of low tem¬perature carbonization because of the shortage of motor fuel and lubricating

The importance of properly bonded rail joints has received the attention of The National Research Council, whose committee will investigate several methods now used and determine the merits of each as applied to street railways. The results of this investigation should be appreciated no less by the mining industry. Literature on the subject of bonding mine tracks agrees, as a rule, "that the work is poorly done." With present day facilities there is little excuse for inadequate track conductivity, and a job well done must be maintained in order to realize results. Many years ago The Union Pacific Coal Company installed their first haulage locomotive, and at that time used the channel pin bond for joining the rails. The system utilized 500 volts and the, relatively small current for a large amount of power, undoubtedly, contributed to the success of the system. The bonding of both rails was considered imperative in those days, while now the bonding of one, rail is considered sufficient in most instances. The recent installations utilizing 250 volts and correspondingly heavier currents required a more effective method of joining the rails for use as an electrical conductor. The company has used the arc-weld bond since its introduction in 1919. The art of electric welding found great favor for various methods of doing the work. The first arc-weld bonds were placed on the outside of they ball of the rail, but the bonds were ill-adapted to rails lighter than sixty pounds per yard, and the results were that grooved locomotive wheels or derailed cars removed the bonds. Familiarity with the process of electric welding brought forth numerous schemes for joining the rails. In one, instance the rails and splice-plates were welded together and with excellent results for a short time. Track movement and vibration finally broke the welds and the method was dis¬carded. Another scheme consisted of placing a channel pin over each end of an annealed copper wire about twenty inches long. The idea was to develop some way of using short lengths of scrap wire. The pin and wire were then welded to the base of the rail. Numerous joints made in this way are still intact, but successful welds were so exceptional that the practice was abandoned. Some of these bonds were welded to the web of the rail, with the result that practically all rails broke at the weld; however, this is our only record of broken rails with arc-welded bonds. At one time a quantity of No. 2 bare iron wire wasp available and was tried as a bond and proved very satisfactory. Two or three strands twenty inches long were used and were welded to the base of the rail. The method was cheap and effective and of some merit for light rails on temporary track. The use of iron wire was criticized because it did not give a balanced circuit; that is, one having equal carrying capacity for trolley and track circuits; and I am of the opinion that this is not always necessary. The total length of bond that is in circuit is so small that it contributes very little additional resistance to the complete circuit consisting of trolley wire, rails and bonds.

Your Chairman and the Program Committee have limited the time allotted to me, and so, with your permission, I will omit the preliminaries, and wade right into my subject. I believe I am safe in taking for granted that you are all agreed that electricity is the most feasible means of transmitting the power used in coal mining. If you are not, then the papers read before the Association in previous years have failed of their object. If you are so convinced, the only question is as to the choice between alternating and direct current, and the voltage. Fundamentally, this is primarily a matter of dollars and cents. With the sole exception of your trolley locomotives, there is no part of your equipment that cannot be operated as well on alternating as on direct current. With your pay rolls at their present high level and the efficiency of the labor you employ at the stage it now occupies, I believe you will agree, first, that everything possible must be done to increase the tons of coal produced per man employed; and, second, that ample power at all times must be available at every machine so that every one of your men can really get out a day's work without any avoidable delay. Speaking Electrically, all this means is a machine instead of a man wherever it is possible for a machine to do a man's work, and full voltage at the machine always, so that there can be no excuse for the work not being done promptly and efficiently-and dependably. The real reason for the selection of one kind of current or the other can best be understood by considering the formula which determines the size of wire required for transmitting electrical energy. The size of the copper required, and, consequently; its weight and cost, depends upon four factors: 1. The amount of energy or power to be transmitted. 2. The distance to be covered. 3. The percentage of loss allowed. 4. The voltage at the receiving end of the line. These factors enter into the problem to different extents, and, briefly, the size of wire depends directly upon the amount of power and the distance transmitted, and inversely upon the percentage of loss allowed and the square of the voltage. From this it will be seen that, with the amount of power and the distance fixed, if the loss is to be cut in two, the wire must be doubled with a given voltage, while if the loss remains constant and the voltage is doubled, the wire may be cut in four; that is, reduced 75 per cent in weight and cost. Now, standard motors are designed and recommended by their builders to run within a range of 10 per cent under voltage to 10 per cent above voltage - 440-volt motor, then, should preferably not be operated on less than 400 volts

The twenty-eighth regular meeting of the Rocky Mountain Coal Mining Institute, which was held jointly with the Utah Section of the American Institute of Mining and Metallurgical Engineers, was called to order at eleven o'clock A. M., Monday, March 11, 1929, President Otto Herres presiding. Introductory remarks were made by John M. Boutwell, Chairman of the Utah Section of the American Institute of Mining and Metallurgical Engineers, who outlined the intent and purpose of the joint meeting, and its co-operative program. He spoke of the in- creased recognition being given to men in the engineering profession by the public, which has recently been manifested by the election of President Hoover, an engineer of outstanding ability, and the re-election of Governor Dern to the Governorship of the State of Utah. He then introduced Governor Dern, a fellow member, to make the address of welcome. Governor Dern assured the meeting a hearty welcome. He spoke of Utah as one of the important mining states of the Union, particularly in metal mining; the magnitude of Utah as a coal mining state being limited only by its market; of the enormous coal resources of Utah, and the problems of the coal mining industry.

PRESIDENT LITTLEJOHN: Before we open the discussion on the Utah mining laws, I want to bring out what I consider a slight misunderstanding on some of the things that I said this forenoon relative to our comparison of accidents. I did not mean to infer that we, as mine officials, are satisfied we have done the best we can to eliminate the accidents, when I was talking about a four-to- one comparison. I do not want any- one to get the idea in their heads that I do not think we are doing all we can. There is not any of us who can state that, even if we better these figures. It is the general understanding that these figures are based upon ratios per thousand man shifts and not upon the tonnage basis that we use. If it were based upon a tonnage basis, I think the figures would be pretty nearly reversed, for we are producing from two to four tons more per man than they do in Great Britain. The discussion will now be continued as I said this morning. There is a gentleman in the audience here that is as guilty of making these laws as I was, and I am quite sure when speaking he will confine himself to the subject of Utah Mining Laws and the prospective results. Before Mr. Monay starts with his paper, I want it understood that this discussion must be finished by 2:30 for the reason that we have still quite a lot of business before us this afternoon.

The Hiawatha pitmouth is located at the head of the middle fork of Miller creek, at an altitude of approximately 8,100 feet. The coal is lowered to the tipple down a gravity tram two miles long, in 16 car trips which carry about 60 tons net. The average running time of the trip is about nine minutes. At the bottom of the tram there are two tracks for the loads and two for the empties. The trip, after being cut off the rope, is dropped by gravity onto a feeder, where the cars are uncoupled and fed one at a. time across the pitcar scales and into the dump. The dump is of the full revolution type, friction driven. On passing out of the dump the cars are returned by a kickback onto the empty car haul. They are caught at the bottom by a brake which consists of a pair of steel squeeze blocks operated by heavy springs. The empties are elevated to the double tracks, where the trips are made up. The feeder, scales, dump and empty car haul are all built on the solid ground of the hillside instead of being incorporated in one structure with the screening plant. The coal is dumped into a small hopper with a capacity of about 15 tons, whence it is fed by a reciprocating feeder onto a scraper conveyor which takes the coal over to the screening plant, a distance of 120 feet. This conveyor is 48 inches wide and travels at 120 feet per minute. The screen itself is interesting. It is of the Marcus Horizontal type.
