it may be clearly seen that one of the most rapidly increasing items in mining operations is the cost of the timber alone, to say nothing of the cost of installation. Consequently, any practical means that may be used to lengthen the life of mine timber will greatly tend to decrease mining costs and result in important economies in operation. The four principal agents by which mine timbers are destroyed are, decay, insect attack, fire and mechanical abrasion. Decay and insect attack are credited with more than 50 per cent of the total amount of timber destroyed in the mines. Numerous methods may be used to conserve mine timbers, such as better selection, preparation, storage and segregation. It frequently happens that good timber goes into places where poor timber would do as well, and timber of inferior quality is sent into places where only the best grade should be used. However, the most effective method of conservation is by treatment with some standard preservative to prevent decay. Some of. the benefits to be noted from the use of preserved timbers are; the reduction in operating costs by decrease in timber purchases; cuts down interference with mining operations due to timber failures on main haulageways; prevents excessive falling of roof in entries by maintaining timber in sound condition; conserves timber supplies and makes possible the utilization of inferior woods; reduces the danger of mine accidents; improves mine ventilation; lessens fire hazard. Our experience thus far with preservatives, while not of a sufficient period of time to establish just what length of life we may obtain from timber so treated, results obtained during the past four years indicate that the intelligent use of preservatives will effect sufficient economies in mine timber costs to justify the expenditures made for this purpose. MR. BAKER (Concluding): Now, if there are any questions you gentlemen would like to ask about our particular operations, I will attempt to answer them. J. H. EMRICK (Sullivan Machinery Company, Denver, Colo.) ; I was wondering how much penetration you get. MR. BAKER: We get between one-sixteenth and one-eighth of an inch; it is a dipping process. With pressure treatment you get-a greater absorption; that is, better than one-sixteenth of an inch. As long as there is no mechanical abrasion, it seems to serve the purpose. MR. EMRICK: Does that apply to the condition of the timber before it is treated? If it is perfectly dry, will it absorb more treatment than if it is partly green? MR. BAKER: Certainly; one of the things we do is to have it thoroughly seasoned before it is put into the preservative. We put some green timber into the mine once, and the fungus went after it right away. MR. EMRICK: What was the difference in the depth reached by the preservative? MR. BAKER: It hardly penetrated at all when it was green. It has to be sound and well seasoned. MR. EMRICK: How long was the timber dipped or treated? MR. BAKER: According to the seasoning. If it was well seasoned, it was left in the hot bath for an hour; if not so well seasoned, it was left for about a couple of hours. C. M. BILLINGTON (General Superintendent, Rocky Mountain Fuel Company, Lafayette, Colo.): Have you found it necessary to treat timber that has been charred? MR. BAKER: No. However, I suppose it has the sane effect; in lots of places they char timber for the purpose of treatment. MR. BILLINGTON: Have you ever tried lime and salt? MR. BAKER: No, this is the only thing we have tried, the creosote and the Aczol; the Aczol is a foreign product. WM. LITTLEJOHN: Which I is preferable, the Aczol or the creosote? MR. BAKER: I couldn't say as to that. MR. LITTLEJOHN: Have you had any tests as to the value of either? MR. BAKER: We have had some of the Aczol timbers in service for a little over four years; we have had some creosote timbers in service

At the meetings of this Institute held two years ago, there was presented a very comprehensive paper on the subject of shearing coal. It was well prepared and contained data based upon actual test and experiment. The conclusions reached showed that where the shearing cuts and tests were made and conducted [ ] there was no advantage but a disadvantage from having sheared the coal. In presenting my ideas on the subject of this paper to you, I do not mean to take issue with the author who addressed you two years ago but only to report the advantages which have recently been secured from shearing coal. All of this goes to prove again the well known fact that what one mine's conditions will permit another's will not. A number of years ago, when most of the coal produced was shot from the solid and when the "good, old" pick miner?s pay was based on the amount of lump coal he loaded out of his room, he was frequently seen putting in a vertical cut in the face as deep as he could do so with his pick. This man was the best ac- [ ] quainted with the peculiarities of the coal and, no doubt, saw that his pocketbook would be fattened more if he put forth the extra effort to make this vertical cut. Fortunately he was well repaid, and his employer loo, on account of the greater percentage of lump produced. Coal cutting machines of various types were then introduced to help along still more the cause of lump coal and, since the natural way to

We all deplore the high accident rate of our coal mines, but when brought to task we immediately attempt to appease our conscience by calling attention to the high tonnage rate per fatality in American coal mines as compared to European mines, losing sight of the fact that the accident rate per hours of exposure has shown no improvement during the past twenty years. Measuring our accidents in terms of hours of exposure, not in terms of production, is the only correct method. Certainly it can be of only scant satisfaction to the miner to know that his chances of getting killed this year are as great, or perhaps greater, than last year, but the tonnage rate per fatality will have gone up. We cannot help asking ourselves why it is the other major industries, almost without exception, have made wonderful strides toward reducing accidents, while coal mining stands alone as the one major industry in which no improvement has been made. It certainly cannot be charged entirely to the increased use of machinery and the increased productivity per man employed, as the other industries likewise, or to an even greater extent, have increased the use of machinery and the production per man.

Safety, from the Latin word "Salvus" -Safe. 1. The condition or state of being safe; freedom from danger or hazard, exemption from hurt, injury, or loss. 2. Freedom from whatever exposes one to danger or from liability to cause, danger, or harm; safeness: hence, the quality of making safe or secure, or of giving confidence, justifying trust, insuring against harm or loss. (From Webster.) The meaning of the word "Safety" by Webster is very explicit, clear, and plain. It is not obscure or imperceptible. What man, woman or child is not familiar with this word? A mere word by itself, but indifference to its significance means the difference between life, death, permanent or partial disability, or injury. There is no question about a safety program being expensive. It is-it produces no commodity-but when properly organized and with a definite goal in view it will pay 'a dividend by increasing the efficiency of the human worker.

One of the most dreaded things which mining men sometimes have to contend with is underground mine fires, which are both dangerous and expensive. In the Reliance mines we have had considerable trouble with mine fires. We have at the present time five different fire zones, three of these zones give us considerable trouble and the other two have not given any trouble since they have been walled off. Fire Zone No. 1 comprises No. 2, 3 and 4 South Entries, about 50 acres are enclosed in this zone. Fire Zone No. 2 comprises the main drift entry from the mouth to the Old Boundary Plane and extends to the crop line, about 10 acres are enclosed in this zone. Fire Zone No. 3 comprises 1 and 2 North Entries from the main slope to the Old Boundary Plane, a distance of about 1,200 feet, about 15 acres are enclosed in this zone. Fire Zone No. 4 comprises 11/2 and 2 North Entries, a distance of 1,100 feet between New Slope and Old Boundary Plane, about 15 acres are enclosed in this zone. Fire Zone No. 5 comprises the inside end of No. 11/2 and 2 North Entries and 3 North Entry from the New Slope to 30 room, a distance of about 2,600 feet along No. 3 North Entry, about 20 acres are enclosed in this zone. The first mine fire started in No. 2 South Entry in No. 1 zone in 1914. Inside of No. 7 room on the high side of the entry, there was a soft piece of coal. There were no rooms driven in this coal and one day a fire was discovered in the solid pillar on the high side of the entry, work was started at once to load out this fire. and several places was driven into the pillar and cribs built where the coal was taken out, but this method proved a failure and a sand pack was put up along the entry between the track and the high rib. This consisted of timber set about 3 feet from the rib and 2-inch boards put behind the timber and sand or adobe put in between the boards and the ribs, and this method gave very good results except that it required close watching as the sand would settle and let the smoke out between the roof and the sand. Fire broke out in No. 3 South Entry in No. 1 zone in the summer of 1919. We sealed this fire off by building 36 fire stoppings, which also enclosed the fire in No. 2 South Entry and we have never had any trouble with fires in this zone since it was walled off. The fire started in No. 2 -zone in 1919 and has been very active ever since. When this fire was first discovered we built new stoppings in front of the old one in the room necks; we also opened up some of the room necks and loaded out part of the burning coal and rock but this did not help any, the fire, would burn out around the stoppings also burn along the roof between the top coal and the roof sometimes nearly across the entry. Several holes were drilled from the surface to the fire area and flushing the fire was tried but this was also a:\, failure, the rock above the coal was so hot that the mud would dry in the hole and fill it. In 1921 we started to take down the top coal along this entry, timber the entry and put 2-inch boards behind the timber and fill in between the coal and the boards with sand or adobe. We have at present over 1,000 feet of this work done and it has given us better results than any other method that we have tried. As the coal burns out behind the timber the weight breaks the timber and it is necessary to renew some of it. Fire broke out in No. 1 North Entry in No. 3 zone in 1922. There was a stopping in this entry that had been put in when the entry was finished some few years before. The fire burned around the stopping on the low rib of the entry, we built another stopping in front of the old one taking down the top coal and extending it up to the roof also digging in both ribs and setting the stoppings into the coal about 18 inches. This fire did not cause any trouble until June, 1924, when we discovered this fire was very active on the inside

Those who remember the years of patient effort and the slow results obtained in the first introduction of electrical coal cutters and locomotives will, I think, admit that mechanical loading of coal is unquestionably being established at a much more rapid rate than any previous application of machinery to reduce manual labor in mines. There are many operators who consider the progress of the loaders today as slow, but considering the number of years it took to thoroughly establish electrical coal cutters and locomotives, and comparing it with the short time that the mechanical loader has been on the market, and the results that have been obtained today, they will admit, I think, that the progress of the latter is much more rapid. It is about 35 years since the advent of the electrical coal cutter and electric locomotive. Their use has brought about these improved conditions, increased tonnage per mine and other features, which are of assistance to the installation of mechanical loaders. The management and the technical staff in practically all of the American mines are trained in the use of electrical machinery and understand its operation, care and maintenance. . There is frequently, a surplus of electrical power and wiring available to take care of the small requirements of the electrical loader. The mechanical loader, therefore, starts today with the ground prepared for it. Those manufacturing companies who have had years of experience in the design and construction of mining machinery, know in a large measure what to incorporate in their designs to make the parts of the new type of machine effectively strong and to operate with efficiency under the severe conditions encountered in mining service. All these advantages greatly assist the success of a new type of machine such as the mechanical loader. In spite of these advantages, however, there are bound to be some failures. All new types of loaders have to be developed. We hear of some that are a success and some that are set aside. The field of application of each type and its limitations first must be determined by actual operation. The earlier loaders had to be changed and improved in design as weaknesses developed. Not all of the new types of coal loaders have been built by mining machinery manufacturers of long experience, and the lack of experience in this line is responsible for some of the early failures. The coal mining company staffs and also those of the loader companies had to learn what the operating factors were that made mechanical loading a success. The difference in results obtained by loaders in different properties under similar physical conditions indicates that the mine management is a very large, if not the major factor, affecting the efficiency of mechanical loading. Many articles have been written on the question of loading. The subject has been quite fully discussed at recent coal meetings and in the technical press. It is not always as easy or simple a matter to form conclusions as may first appear as to one's own particular loading problem. Mechanical loading is a comparatively new art, and many companies while claiming that loaders are quite successful, do not have an accurate line on the actual saving they are affecting. Many of them have only a few of the factors taken into account in their costs. Many loaders have been generally bought without very careful consideration given to all details and except where extremely favorable conditions prevail, failure resulted. When contemplating the installation of mechanical loading, one naturally desires to select the type of loader that will, fit his mining conditions. The things
