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.

PRESIDENT LITTLEJOHN: The paper of Mr. Emrick will now be open for discussion for about twenty minutes. The meeting is now open for discussion. MR. EMRICK: There is some question that may have occurred to you at different times, that is how are you going to tell when the bits are properly made? A fairly good rule to go by is when the used bits come out of the mine, if half of them are bent and half of them are broken, the average is pretty good MR. GEO. B. PRYDE (Union Pacific Coal Company): I would like to ask Mr. Emrick if he has any figures as to the saving of Dower with the different styles of its. MR. EMRICK: I suppose you mean chisel point bits and pick point bits? MR. PRYDE: Yes. MR. EMRICK: So far as I have been able to learn, the only reason why chisel point bits are used is to prevent coring that might be done by the cutter chain. The pick point bit, of course, is the proper thing to use. It can be used when the position of the cutter links in the cutter chain is right. I do not know of any figures which give power consumption ratings on the use of pick point and chisel point bits, but there are tests and ratings, etc., which have been taken- which have been tested as against different bits, which have been given proper clearances against bits not having been given proper clearances, and they will run,-in their saving in power, they will run 20 to 25 per cent. MR. A. C. WATTS (Chief Engineer, Utah Fuel Company) : I would like to ask Mr. Emrick if he has any record showing the saving in power on using the alloy steel chisel bits. I know that several experiments have been made; I do not recall the figures now, but we had a very decided saving in power. MR. EMRICK: I haven't any of the records. Do you think that is because of the steel that has been used? MR. WATTS: Well, they were all sharpened by the same man and used in the same machine, and at the same shop. I do not know the composition. It is "Red Star" Vanadium that I had in mind. MR. EMRICK: I have not seen any records. Some companies are using the tool steel bits because they stand up a little bit better. MR. BENEDICT SHUBART (Secretary) : I was going to ask Mr. Emrick about that question. There is one company that does not recommend tempering the bits. They recommend using not exactly self-hardening steel, but one that is bard enough without quenching-they use 80-90-point car- bon but about a 70-point manganese, not exactly self-hardening steel, but they do not temper this at all. Will Mr. Emrick state if a steel of that kind could be worked in the bit sharpening machine that his company makes, as it

GREETING Hail! Hail! the Coal Miner, Damn the operator, damn the operator, Hail! Hail to mining coal We'll tell 'em how to run the mines. Oh, we'll send out a questionnaire And we'll quiz 'em, we will razz 'em for fair, We'll ask about the profits and order them to stop it Tell the world we're going to stop right there. Hail! Hail! etc. NASH AND PRYDE Tune, "Gallagher and Shean" There are two mining men, the best I've ever spied, One is Mister Harry Nash, the other Mister Pryde. When these two fellows meet it surely is a treat, The things they do, and the things they say, And the funny way they greet. Say, Mister Harry Nash, Oh, Mister Harry Nash, Tell me what's on your mind this evening, Mr. Pryde; I have heard an awful lot of that steep coal mine you got, And I wondered if some one had up and lied. Oh, Mr. Pryde, Oh, Mister Pryde, It's so steep it seems to lie upon its side. If it were steeper than it is, it would put us out of biz, Absolutely, Mister Harry Nash, positively, Mr. Pryde. Oh, Mister Harry Nash, Oh, Mister Harry Nash, Somebody said that at this new mine you've begun 'Fore you mined a lump of coal, had to burrow like a mole, And of rock you dug out many a million ton. Oh, Mister Pryde, Oh, Mister Pryde, I hate to think of all the dough I supplied. I believe the Moffat Tunnel bore won't cost a single dollar more I don't think so Mister Harry Nash, I agree with Mister Pryde. PARTING Tune, "Leave Me With a Smile" Though a sea of strikes and low price squabbles, Follow us the while; Once a year we gather just to show them whether We still wear-a smile; Rocky music coal still packs a barrel full Of timely fun sans guile, Rocky Mountain Institute can follow such And smile its yearly smile.

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.
