Coal is the basic necessity of our present-day civilization, and those engaged in the industry, whether miner, day-man, pit boss, tipple boss, superintendent, salesman or operator, have a direct responsibility to the public at large. Our country is blessed with a great supply of Bituminous coal, upon which it must largely depend for its industrial prosperity. Anthracite coal, in its relation to our economic situation, is a small factor, as its ratio of production to Bituminous coal is only about one-sixth. However, within the last ten years, electricity and oil have largely displaced the use of coal in industry, so that the use of Bituminous coal is decreasing, relatively, and the potential production of Bituminous coal has largely increased since the war. High wage scales and high freight rates make the delivered price of coal to the consumer so out of proportion to the cost of electricity and oil -and strikes make the supply of coal so uncertain-that industry is rapidly turning to electricity and oil. The energy in a ton of coal can be transported, by electric current, a distance of 250 miles for 78% of what it costs to ship the coal in bulk, by rail, in the East-and, for about 60% of what it costs in our section of the country. The use of fuel oil, distillate and gasoline, in industry, has increased by leaps and bounds. Especially was this noticeable during the strike this year, as the large packing plants in Kansas City, Omaha and Sioux City (that formerly used nothing but coal) are now practically all using oil. This also supplies to other industrial plants throughout our territory in Texas, Oklahoma, Kansas and Nebraska. Many railroads are using oil, as are also the smelters, cement plants, etc., etc. Ten years ago, 100% of the threshing in the state of Kansas was done with coal-today not over 25% of it is done through that means-and so it goes all along the line. The use of our coal is being yearly more restricted in industry. In the case of domestic consumption, the circle is also ever decreasing.' In small towns and on farms, kerosene, gasoline and wood are largely utilized for cooking. For the past four years, along any country road, it is a common occurrence to hear a buzz-saw cutting old fence posts or timbers taken from creek bottoms. Many thousands of tons of coal are displaced each year through the use of corn and cobs. In larger towns, gas plants have been installed, and many housewives use gas-in communities contiguous to natural gas, that is used for industrial and domestic purposes. The time has gone when industrial and domestic consumers or dealers are satisfied to buy anything that is black-competition among the coal-producing states is keen, and will become more so. Eastern and southern fields are turning out splendidly prepared coals of high quality, and with their lower freight rates to competitive territory, will entirely nullify the use. of our Western coal unless-

MR. CHAIRMAN AND GENTLEMEN: To be invited to address the members of The Rocky Mountain Coal Mining Institute on a particular subject is an honor I sincerely appreciate. The subject of this paper is, ?The Advantages of Having Such Men as the Fireboss Under State, Rather Than Corporation Jurisdiction." On the fireboss, primarily, depends the safety of the mine. When all the rest of the mine workers are still comfortably sleeping in the wee small hours of the morning the fireboss steals noiselessly away, from his bed to take up his daily task, a tour of inspection. He enters the mine, he inspects alone they workings that will be filled with men whose safety is in his keeping. Loyal to his fellow men and responsibilities of his position; he seeks for danger in every place, on every road and travelingway; going over caves, through dangerous places where none of the others are expected or allowed to go alone. How many of us give a thought to these dangers and the faithful work that this guardian performs for our safety. After the fireboss has made this round of inspection, he reports all the dangerous places to the foreman and enters them in the book; he is supposed to have performed his duties; he has no authority to enforce his recommendations. He has found a number of rooms that have not been timebered as they should be for the safety of the digger; he has told the diggers to they timber, up better for their own safety; he has kicked to the foreman about these same places. These conditions. continue until there is an accident. The fireboss reports, broken crossbars or bad roof on a roadway or some other danger to the foreman, but the foreman does not have it fixed, making, excuses, as he cannot put any one on that work today; or that it will stand until some idle day, and that is the way things go until the fireboss gets so he wonders what good he really is, is it any wonder it is hard to get good men to take this position of fireboss? The remainder of the shift the fireboss is used as a general roust-about, having to do such, work as building stoppings, help the timberman or track layers, pull rails out of danger in pillars, a trapper is off and he is told to trap that day, when the mine is idle he is laid off to cut expenses. That is the way the fireboss is treated. The fireboss is not merely a merely a necessity to be lightly regarded but a factor whose authority should be unquestioned. The fireboss has made his district and knows just what conditions the workings are in, and sees lots of dangers that the foreman does not. In the morn-

Briefly, the machine consists of a steel frame mounted on roller bearing wheels and axles, an electric motor, a fully enclosed speed reduction gear unit, a specially designed centrifugal pump driven through a friction clutch and silent chain, a mixture tank and agitators, and all necessary operating and control mechanism. The wheels are mounted on solid roller bearings made of special roller bearing steel, and are cast with deep chilled threads. The axles are of high carbon axle steel. A General Electric Company motor, of special design to exclude dirt and moisture, is used. It has an unusual overload capacity and a maximum torque at starting speed. Special arrangement can be also made for storage battery operation. The motor drives from one end, through a flexible coupling, to the speed reduction unit, and from the opposite end, through a similar coupling, to the pump clutch. The design of the flexible couplings is such that the drive is reversible. The speed reduction gears are enclosed in an oil and dust proof housing. All spur gears, as well as the main drive clutch, are made of steel forgings, with accurately cut teeth. An aluminum bronze worm wheel and special heat treated alloy steel worm provide the speed reduction for the traction drive. The worm shaft is mounted on Hyatt roller bearings and the thrust is taken in each direction by ball thrust bearings. The main drive shafts are of special alloy steel and operate in Hyatt roller bearings. The slow speed shafts run in extra large bronze bushings. Ample and constant lubrication is provided by splash from the gears running in oil. The Mudite pump is of special de- sign. A renewable wearing plate protects the pump casing from the natural wear of the mixture. The open runner is mounted on an extra large shaft which runs in a Hyatt roller bearing on the pump end and in Timken roller bearings on the outboard end. A special cage prevents water and grit from reaching the pump bearing. All thrust from the runner is taken on the Tim- ken bearings and these bearings also provide for the accurate and easy adjustment of the runner. The pump is driven by a silent chain, which operates on cut steel sprockets, from a friction clutch. The clutch is designed to secure long wearing qualities with minimum attention and its adjustment is easily effected. It is mounted on Hyatt roller bearings and the clutch drive shaft also runs in the same type of bearings. The pump discharges through a nozzle, which is adjustable, and controlled by the operator. The mixture tank is of approximately 650 gallons capacity. It is provided with a mixing well constructed of perforated plate screen to prevent large hard particles from getting into the valve or pump. The tank is filled through an opening in the top directly into the mixing well. On a shaft running longitudinally through the tank are arms so arranged that the mixture is thoroughly mixed and kept in continuous circulation from end to end. This shaft is driven from the speed reduction unit by a steel roller chain operating on cut sprockets. The traction drive is taken from the worm wheel shaft through steel roller chains of extra large size that run on cut steel split sprockets on both axles. An idler sprocket provides for easy chain adjustment. The axles are mounted in solid roller bearings in fully-enclosed dust proof housings, which support the frame through coil springs. These springs eliminate twisting strains on the frame on account of track irregularities and also relieve the working mechanism from road shocks. The speed reduction from the motor to the wheels is such that it gives an operating speed of approximately ninety to one hundred thirty feet per minute. The brakes are of the conventional shoe type and engage the wheels on both axles. They are operated by a hand wheel conveniently located and
