At Rock Spring s No . 8 Mine, I suggest that you go into these recommendations that we double up in some of those entries, as hlr. Weichel is under the impression that we can do that and reduce our costs to some extent . I am sending these reports to you, as &. McAuliffe told lir. Weichel in nzy- office Saturday that we would not discuss any of the operating problems until his examination was completed, and then vie would get together some time before he goes back and go mrer the recommendations .

In the No. 8 Mine, the seam varies in thickness from 5 to 8½ feet, and is mostly mined by shaking conveyors and Duckbill loading heads, al.though there are a fev, pit car loaders and chain conveyors operating. I have no comments to make on No. 11 Road section, where there are five places working, and old men are being employed. This section was in excellent condition, and under the supervision of a very capable and careful man. The older face employes are giving a good performance, \ 1 all things considered. ~, \\ • - ,.J' j J ' The r.est.. of:-...the production comes from .se¥en entries driven'Y l / ( ~ o; west?) off No. 8 Slope, and a little production from the finishing up of the No. 1 Plane section. In al.l but one case on No. 8 Plane, namely Entry No. 20, but two places are working on a road, and I wish, at this time, to draw your attention to the distances that the haulage locomotives in each case an.1st travel to reach the working places: rio. 20 Road N'o. 21 Road No. 22 Road t!o. 23 Joad No. 24 Road No. 25 Road ?Jo. 26 Road 'l 3;200 feet 1§600 feet 2,300 feet 3,200 feet 3,500 feet 4,000 feet 3,800 feet :fZ I 5 places 2 places 2 places 2 places 2 places 2 places 2 places '), I/ �- 2 - In each of the above cases, with the exception of gangway No. 20, the haulage locomotive is working only about two thirds capacity. In order to reduce costs, I have two suggestions to make. The first is that Entrie s Nos. 25 and 26 be stopped, and one of each of the four units be placed on Entries Nos. 21, 2?, 23, and 24. This would eliminate two Unit Foremen, four Motormen, and two locomotives, and maintain the same production. At No. 4 Mine, three places on an entry are ,·,orking very successfully, and it is the feeling of Superintendent Overy that three places on an entry woulci be practicable and possible in No. 8 Mine. The second suggestion is to add one working place to each of ;,._ ~ ' ..the entries excepting No. 20, which would mean an increase of six working L. places. Assuming that a fair performance per shift would be twenty-five cars, this would give you an additional three hundred cars, or 750 tons per two shifts, with, of course, the additional costs of the unit crews. / You can readily see what an increase of 790 tons per day would mean in reducing your fixed charges, namely, main haul transportation, supervision inside and outside, company men, clerical and general expense. I have checked vii.th the Superintendent, and am advised that the main-haul transportat,ion system is ~ple ;/> take cai;e of~ ~is ..._ increase per shift. I - e.-l I ~) c,..._, ,,l , .c.. I • ,t..L..,, --•-.AJ.-1/ I am, however, not,. acquainted with the...'dumpliig , ti. 1- v~- L,-; ~e, / / .,,.t... , ... cai)a.Ci.t:r--of-the tipple; which necessarily must be studied out. I I would recommend the second suggestion, namely that of increasing production, and §1.18gest that one additional place at a time be started in each entry, carefully watching the effect on the main- line transportation and the car supply to thatb'-~"/ i:oe1, so that additional . J- �\ - 3 places ~~uld not reduce the present producer performance. In driving the three rooms on an entry, they should be so timed that as the robbing place finishes , a solid place is prepared f or starting, and the middle place has reached its limit and started back, when the third outside place is half- way advanced in first mining. I wish also to draw to your attention the excellent condition of t his mine as to cleanliness, upkeep of equipment, and general performance of evecy workman, whether company man or face worker . I t r aveled the entire length of the main haulage system in the mantrip, and the track condition is perfect. I honestly feel that all wor kmen in this mine, as well as in No , 4 Hine, are giving the best day ' s per formance they possibly can. �Your :'rcsiJcnt, ! :c,\uliffe. has e.dvised we he is desirous of incrcasin3 ?:..~o.i:.:ct:!..c."! ~.l1cre possible from all of t.he :nines \':ith t he feet, c?.nd is r.1ost.l:, Lcl..:.1e6. oy :::haking conveyors and Di.:.ckbill 101:.cling heads, cl.thou::.1.1 ti;e1--e .::re ~ fe·.: ~it car lo:iders c::1:.l chain conveyors operatin::;.

McAuliffe, has advised me he is desirous of increasing production where possible from all of the mines with the exception of Hanna, where you are limited for a market for this fuel . In the No. 8 Mine, the seam varies in thiclmess from 5 to 8½ feet, and is mostly mined by sha.'ldns conveyors and Duckbill loading heads, although there are a. fe\-; pit car loaders and chain conveyors operating. I have no comments to make on No. 11 Road section, wnere there are five places worldng, and old men are being employed. l This section vras in e~cellent condition, and under the supervision I of a very capable and careful man. The older face employes are giving a good performance, all things considered. The main production comes from eight entries driven and being driven north off No. 8 Slope, and a little production from the finishing up of the No. l Plane section. In all but one case on No . 8 Plane, namely Entry No. 20, but two places are world.ng on a road, and I wish, at this time, to draw your attention to the distances that the haulage locomo- tives in each case must travel to reach the working places: ----- J �- No. 20 Road No. 21 Road No. 22 Road No. 23 Road No. 24 Road No. 25 Road No. 26 Road No. 27 Road 2 - 3,200 feet 1,600 feet 2,300 feet 3,200 feet 3,500 feet 4,000 feet 3,800 feet 500 feet 5 places 2 places 2 places 2 places 2 places 2 places 2 places 2 places In each of the above cases, with the exception of gangway No. 20, the haulage locomotive is working only about two thirds capacity. In order to reduce costs, I have two suggestions to make. The first i s that Entries Nos. 25 and 26 be stopped, and one of each of the four units be placed on Entries Nos. 21, 22, 23, and 24. This would eliminate two Unit Foremen, four Motormen, and two locomotives, and maintain t-he same production. At No. 4 Mine, three places on an entry are working very successfully, and it is the feeling of Superintendent Overy that three places on an entry would be practicable and possible in No. 8 Mine. The second suggestion is to add one working place to each of six entries excepting No. 20, ,vhich would mean an increase of six v1orking places. Assuming that a fair performance per shift would be tl'Tenty-five cars, this would give you an additional three hundred cars, or 750 tons per two shifts, \'fith, of course, the additional costs of the unit crews, You can readily see what an increase of 750 tons per da,y would mean in reducing your fixed charges, namely, main-haul .. ,- �/ // - 3 - transportation, supervision inside and outside, company men, clerical and general expense . I have checlced with the Superintendent, and am advised that the main-haul t ransportation system is ample to take care of this increase of 375 tons per shift. I have checked the dumping ti.tn.e required at the tipple. and find that 650 to 700 tons can be dumped in seven h0urs . I would recommend the second suggestion, namely that of increasing production, and suggest that one additional. place at a time be started in each entry, carefully watching the effect on the main-line t ransportation and the car supply to that entry, so that additional places ,.,.ould not reduce the present producer performance. In driving the three rooms on an entr-.1, they should be so timed that as the rabbi!'~ place finishes, a solid place is prepared for starting~ and the middle place has reached its limit and started back, ,·,hen the third outside place is half-wa;r advanced in fir st mining. I wish also to draw to your attention the excellent condition of this mine as to cleanliness, upkeep of equipment, and general performance of every worlanan, whether company man or face worker. I traveled the entire length of the main haulage system. in the mantrip, and the track condition is perfect. I honestly �r '. - 4 - f eel that all ,·,orkmen in this mine, as well as those in No . 4 Mine, are gi ving the best day 1 s performance they possibly can. , , ~ t I l I I.

The original seam of coal is approximately 35 feet in thickness, of which four feet is left for roof support, as the overlying strata break up very quickly when exposed to the air. Four to five feet of I /!I bottom, laminated, poor grade coal is not mineable, and is left down for protection against the possible heaving of the bottom shale. You have in progress a plan of rearranging your mining scheme which will considerably change the present transportation system, v/.Z by taking the coal to the surface by way of L Plane instead of the long underground hauls to the present main slope. This is an excellent lay- out, and should be speeded .along to completion. The new plan, however, does not eliminate the necessity of driving numerous inside planes in order to mine out the coal by room methods across the pitch. I have been informed that a large Capital investment was made for the purchase of eight Joy loading ma.chines, and naturally this expenditure should be justified. many years, It has, therefore, been the plan, over to mine the coal under the present system which, without any question of doubt, is the best possible method if loading is to be done entirely by means of the Joy loading equipment. It is true that a comparison of Producer Performances shows the Joy loader to be greatly superior to the Duckbill and shaker conveyor I �- 2 - method, but these comparisons are based on statements submitted to the management which show the average performance. An average performance represents a number of poor performances thrown in with a number of excellent performances, so that, out of the total, we have a fair performance. To illustrate m,y thought, I would refer you to two concrete examples which I have encount ered in my visits to the Hanna Mine and to the Rock Springs No. 4 lli..ne. At Hanna mine in the J Plane section, where pioneer mining is being done by Joy loader and undercutting equipment, the vein being mined measured 8½ feet high, and the room approximately 28 feet wide. The comparative place at the Rock Springs No. 4 Mine is Unit No. 39 , Entry No.~, vthere the vein being mined is 8½ feet in thickness, and the room approximately 23 feet wide . ·/ At Hanna 44 cars were loaded in seven hours, and..ei-ght men were employed, making a total of 176 tons, or approximately 20 tons per man shift. No extraordinary work of any kind was done at Hanna except the moving in and out of the Joy loader and the undercutting of the coal. The coal vras blasted by firing four holes at once in the bottom bench and three holes at once in the top bench, making two firing operations. At Rock Springs No. 4 lline, the room was driven up an approximatel~ 10-degree pitch for a distance of 168 feet, and four men produced 50 cars, or a total of about 75 tons, showing approximately 19 tons per man shift. In this room, in addition to producing this tonnage, the men carried from the1entry and stood 8 posts and two -l--~~r1t' �- 3 crossbars, and put one pan extension in the shaker. The coal was also undercut, but the blasting was done by firing seven holes one at a time, making seven distinct operations. In my judgment at least one fourth of the time worked by the crew in Rock Springs No. 4 Mine was spent in work which was not necessary in the Hanna Mine, so that from a viewpoint of actual face performance, the Rock Springs No . 4 lli.ne greatly exceeds the Hanna Mine. ~ o/- To -show further v1hatl\.comparisons mean, in the Rock Springs No . 4 Mine, very difficult pillar extracting conditions are encountered, such as the condition found in No. 9 Road, and which presents itself l in every road in this _mine, namely, the removal of the entry stumps or chain pillars left in between the haulage entries and the ventilating entries . This coal must be hand loaded into a shaker chute, as it is impossibl e to make a good recovery with either a Duckbill or Joy loader in such a condition. The result is that three men, v{orking very hard, loaded only twenty cars, or thirty tons, shovdng a performance of 10 tons per man shift. \'/hen we compute the average figure, we add the 10- tons- per- shift pl ace to the 19-tons- per-shift place, and divide by 2, giving an average ·producer perfor mance of 14½ tons. I have always tried to follow the practice of comparing good condit ions and bad conditions in-sep~rate-mine& separately, in order t o arrive at a fair conclusion. ~ time in the Hanna lli.ne was l imited, but I have made a very caref ul study of the mine map, and, after having the Engineer make a careful check of the coal mined, I find that you are making a recovery [ I· fI l �-~-----~-------- - 4 of but approximately 24 per cent of the original coal in place. Of course, it will be understood that an add.itional recovery will be :!re~ ;;;;- /\ the reserve pillars are mined, and the top coal in the entries taken down, but this will also be the case in the proposed method of mining by rooms up the pitch. After seeing the operations of the Joy loaders and the shaker conveyors with Duckbills, I am thoroughly convinced that a study should be made of changing the pr esent system of mining, that is, that the chamber rooms should be driven up the pitch instead of across the pitch. -a.ad~ Ai-series of parallel development entries should be ~4.~.,..,..._;h.~ driven across the pitch, being laid ou7\ so that the rooms would be approximately three hundred feet in length, and leaving a fifty-foot r barrier pillar between the room faces and the haulage entry abover anci,,tha.t'°1ese rooms should be mined by means of shaking conveyors and Duckbill loaders in the same method as the mining is at present being -:!-,. done, that is, mining nine feet of the bottom bench, and then the~top • nD ;.; 'f!.pC:r<'Tf.. bencn', in two distinet,. operations. I am attaching hereto a print showing the suggested plan of mining, and recommend that two places G\,C.. ~ ~ be driven off No. 2 North Entry from L Plane'\in an area adjacent to the Monolith Portland llidwest Company's property, and that this test be under the constant supervision of an impartial. official, -rhis official ,#w--.,__"J d_ 4'0 keep a running report of all conditions encountered, especially material and car supply, and the calibre of the workmen engaged in ,~ driving these rooms: From my observations and inquiry, I have found no place where an actual comparison has been made between the two mechanical units in question covering identical mining conditions ' I �7 l_· - - - - 5 that is, the completion of an entire chamber room covering all benches of coal, In making this test, I would recommend that the rooms be driven 28 feet wide and the pillars 35 feet wide, as it is generally conceded that a pillar running lengthwise ~ the pitch is twice as strong as the same size pillar running lengthwise across the pitch. If this plan of mining proves practical from a cost and~ ~ producer standpoint, I would suggest that the change-over be gradually made, and a portion of the present Joy loaders be used for entry development and the opening.of chamber rooms. The thought I have had in mind of driving these rooms is to <:- ' ~ lay them out in groups of -s4¼ rooms to a panel, and then leave a solid pillar forty feet in thickness for the entire length of the ) room, so that, in case of the necessity of sealing off an area only I two seals, one across the haulage entry and one across the ventilating entry, would be necessary. I Further to the above plan, I wo~d ;uggesythat a double entry be driven from L Plane toward the Monolith PortlaJ Midwest Company's - / I properly above the block wher e the above test /i's to be made, until the barrier is reached. / I-11ould- sug.g-.est-tlliMl f hat two rooms be driven 25 I feet in width, leaving a 55-foot pillar, and, after the room coal has , been completed, that a test be made of driving a 15- foot-wide place in the bottom bench only up through the center of the pillar to the limit , and then r etreat on both sides and with whatever top coal may fall . This pr~ctice is simil.ar to a practice being carried on in the Mammoth Vein, Cranberry Colliery, at Hazelton, Pennsylvania, where the seam is approximately 24 feet m thickness. I �6 I am thoroughly acquainted with the fact that there is a possible fire hazard in the removing of pillars in this field, but, with the plan of mining suggested, a quick seal can easily be established in order to smother out any possible fire. If the above first-mentioned plan is practical and feasible, the economic results would be as follows: 1. An increase of approximately 20 per cent in recovecyj 2. The pillars lengthwise of the pitch will greatly diminish )<..- the present sloughing off of the pillars across the pitch, as the tendency at present is for the pillars to tip, and it will give better roof support. 3. Approximately tv10 thirds of the track work now necessary will be eliminated. 4. The correction of the accumulation of road-bed dust now found in the present rool'.:lS, as the Duckbills can practically sweep a place clean. ~ -' The complete recovery of the four feet_;Jf good coal now left in order that the Joy loaders may work on a level base. 6. The opportunity for a concentration of production. Considering a fair performance of 30 cars per shaker unit, it would take but nine working rooms, plus three sets of development entries, to maintain the present output of 700 cars per two shifts. This could be ma.de possible by having three rooms working on each of three development entries, all tributarJ to L Plane, with quick and vecy economical transportation. I l �- 7 7. In mining up the pitch, the smooths in the seam could be fully maintained across the room instead of cutting through several layer s, as i s now being done by mining across the pitch, necessitating the const ant trimming of the weathering exposed smooths, or parting...-a.., 8. The elimination of very expensive hoist and electrical. wiring installations through the elimination of driving numerous planes. 9. A better control of the ventilation system, reducing the number of stoppings to be built . Conclusion: I I do not in any manner wish to criticize the l management in its present system of mining, as I feel it is an excellent plan, and the only good one for using the Joy loaders, and I am offering my ovm suggestions solely for the purpose of trying to be helpful in r educing costs and making a better recovery of the original. coal. An incr ease of 20 per cent in recovery would greatly reduce the development j cost per ton. I would welcome the viewpoint of any of your practical Superintendents covering my recommendations. I would suggest, however, if a test is to be made with the Duckbill and shaker conveyor, that the I l I work be done on one shift, either day or night, under the constant supervisi on of one impartial official.

The second sugg0stion is to add one ~-r orldng placa t o each of s:bt entries excepting !,!o . 20, v,nich v;ould r.iea.n an increase of six working places. Assuming tha.'v a fair pei~:ro:emence per shift nould be t wenty-five cars, this would give you an a.dd:l.tional tlu~cc hundrad cars, or 750 tons per two shifts, t·.rith' of course, th0 additional costs of the unit ore\'ts. You can r ecdily see uhZlt a,."'l i11crease of 750 tons par "ixed charges, namol.y' main-haul day would mean in reducing y our .i. �- 11 transportation, supervision inside and outside, compal'\Y' men, clerical and gener al expense. I ho.ve checkecl with thG Superintendent ~ and nm advised that the main-haul tra'1spor t ation system is ample t o t nke care of this increa se of 375 t ons per shift .

I I have just talked with the Blue Network people and it is quite evident that they would not feel ju·s tified in 11 picking up 11 our meeting twice for a national hookup.

If the broadcast is a factor in Mr. Jeffers' possible attendance at the luncheon meeting I am afraid that is out unless perhaps an arrangement could be made through the local station in St. Louis whereby a few of the nearby stations might be covered. I am suggesting this possibility to Mr. Weigel on the telephone today, I am also suggesting to Mr. Weigel, who has sent me a proof of the program, that Mr. Jeffers' name remain on the program, that no subject be given for his remarks, and that in addition to his title as President of the Railroad Company, mention be made of his title as Rubber Administrator for the Uar Production Board.

A general discussion vras carried on as to procedure, practice, and policy of the Institute, the session continuin.3 until noon. Many questions CD.me up fol" discussion, and all delet!.:.tes were requosted to give fiveminu·i:.e talks on the problems of the 8cctions , handing in a typewritten memo of sarc.e. the firs"t session, at \·1hich Br. Euzene t\cAuliffc A good deal of the time was taken u9 on .t~onda;y mornine by Colonel Arthur V. llcDermott , director of 3clective Service for t he City of New York, who di scussed t he policy of the selective service organization as applying to engineering students and young en6ineers, and particularly t.he question of deferment . Colone l ::cDer;n.ott stated t hat all men necessary in tho na.r effort engaged in essential industries r;ho cannot be replaced because of u shortage of 9roporly trained. men, whose induction into the militariJ service ,-.ould result in a loss of production, 11ould receive deferment. He stated there v:as a serious shortage of en~ineers, and consequently engineers 3!1d engineer inL; students had been generally deferred by the local boards. However, he \'./arned thn.t in the future the Ar i,vf 1 ~ need of engineers even more than in the essential industries migM. elimirrn.te t his deferment. The q_uosticn ,1a.s r D.ised c.s to r1hether engineers' talents ,,ere r;ast.ed ,·then they were drafte d. 'The Colonel stated that the .~.rw::r exv.ntlnes the ability, history , o.nd buck3r ound or every~ inducted into the service, nn<l places them ,·1he::r0 t hey uill be of most use to their country. Some of the :.:c~bers ·.-,ere i nclined to dispute this, stating ~hat e;icamina.t ions were often conducted by subordinate officers totcl.ly iiithout knowl ed.<;e of engineering abilities and how they could be put to profitable use. 1:r. Jay A. Carpenter, delee ate from rJeva.da., stated thac- the local boards in 1'?e\·~1a. v:ere overzealous in takine young engineers for se1"Vice in the 1~enks. Ho a.s!ced tho.t Colonel !!cDermott come out to 3eno and eh'i)l ain Selective Service aims to the local group . Colonel ·1:0D0rmott adr:iitted tha.t no doubt because o:!' overzealousness mistakes nere m.ndc, but these, he thought, could be corrected. The discussion ,,2s oost interesting. T~1c seconJ sessi on ,,as ce.11.ed to order at 3:15 p .n . on L:ondey, and l o.Gtcd until 5:15 p .m. A.B. Kinzel, Ch:drmen of' the Papers nnd Publications Committee of the Institute, discussed the activities of that Co.::.~nittee. Hr. Sumsn ·su~~ested t h;\t more papers of an elementn.ry nature be printed, and there was some comple.int about delays in the notifications that papers had been accepted. Chair.man Suman e.v.pla11;ed this was a rather involved opsration, and that, ,·;hen o. pnpcr was vn-itten, it ~1ns sent to a comr:rl.ttae 1'Jho wont into the subject matter of the paper �,,. - 3 - most carefully. If this conlrl'ittee could not fulbr o.11ree it was sent ~ f " u ' 10: • urther reading and editinz by different members throughout the Um.ted States, and this, also, took a great deal of time, May I say, p::lrsonally, that anyone v,'ho \'Trites a paper for the Institute may be c.7sured that, while the paper will receive c:.ll'cful consideration, it r;ill also be subjected to the most minute scrutiny and discussion by co:nr,rl.ttee members bef'orc it is even accepted, nnd o. e reo.t rauny papers, \'ihile accepted for reading at t he Institute mectinBs, are not published . Some discussion er?sued rTith regard to the ,10:rk of student c;uidance, that is guidunce of student en3ineers, and it was pointed out that this ad.vice i s a.vailuble if requested. There ·\·,e.s some discussion as to a method of instituting a cam9oign to increase the endowment funds of the Institute in order that the activities might be enlarged, and it rrns thought the.t large endowcents were necessar,J so that t he Institute could carry on its services to members in times of depression when income from dues and adver tisin$ l ags. llr. Parsons e},._-plnined the purpose ;md nature of the various endowment funds, From this infomiation, a nd the in.formation Hr. 1lc.Auliffe has given me, I am sure that the funds of the Institute are looked after in the most neticulous vray, I!lru1Y men £;ivinf, their entire time to t he investmints of the Institute, and giving as close attention to the finances as they do to their personal business, all this done ,.iithout any cost to the organization. It developed that there were about 10,000 members of the Institute, ::md the o.ttcndnnce at these sessions waD very l or ae. :'.'h ile a good iuany people thought that the ettendance would lo.s this year, it devclooad thut the uttendance \"Ins a little better than it tra.r; a yea."(' ago, so that the o.tt,cndo.nce, interest, and financial affairs of the Institute ure in excellent shape at the present ti.!r.e. This sesnion ilaS carried into an evening .c.eeting . Some members ,;;ere somct1hat critical of the parent organization, inasnuch as they seer.iad to thin.~ it should allocate funds for the social activities, but this mo.nifestly cannot be done, ,,hen consideration is ~i ven to the nn.ny nctivities of the Institute, .and the expenses incident thereto .

There i78N t ,·10 of those meetings Going on at t.no same ti.rae , �6 so I attended the one on the use of Diesel locomotives underaround. Dr •. L. E. Young, encl lJr. Philip B. Bucky were Chairman and A;sociate Cl_1e.l.I'i!'1an, rcsp7ctively. This nns a statement o:f the operation of . diesel locomotives underground in tunneling oper:itions for the water ~;1ue,uuct. in th: State of rlew. Yorl{. The presentation was made by Fred . 0 •· t~ef~l, Chief Eneineer of the Contractor, and a. statement of the 1..estr..1.ct:1.ons imposed was made by :Jilliam D.

I think for the particular case in nind, thJ.t is, the driving of these tunnels, p1"0bably the diesen is n GOOd forn of haular.e, but I am convinced that the sto.r age- battery locomotives could have e iv0n comparable, if not bettor, service. Thera ,•;er0 trro shafts, one nbout l,l►oo feet d.cep and one about 300 foot, these tunnels being driven fro~ the foot of these shufts, t he shafts being used for the taki.ne of material and men into the t.unnel::i, o.nd for ventilation. The ~oint mde by those iµvinz the pnper-s and the discussions in fl!.vor ol' the loconotives ,·:ns t.hat, on nccount of the e;as met ·.dth in these tunnels, thcs0 loconotives rcc;,uire the company to keep excellent sources or ventilation, and that the r esale value of tho diesel loco:,10tives ,;;:,s very nuch mor0 t han th:.i.t of the electric locomotives, also that the accidents from diesel loco:notives r,ero much less than ;:ith the elcct,ric locomotives. This comria.rison t;as not an cqltltabJ.c one G.5 they dici. not stu-c.e hou inony miles the electric loco.:-::iotives trnvele<l or hoi·: many t7ere in uso in the United States, and ho,·: very- fen, compnrntiwly, of the diesel locomotives ,'Tere in use. 'l'he Lubor 1;:ien .!'ether prided t,hc.."'ll.Solves on the very ri,sid regulations they im:1osed upon the contractor resa.rd:i.ng inspection ond operation. The Bu<"eau of t unes enzincers merely stated that they considered the diesels perfectly safe if they were operated under the restrictions imposed by the Dop:,.rtment of Labor of the Sto.te of rlevt York. Dr. Carpenter, in discussing the diesels, stn.ted. that he could see no necessitJr for putting another t ype of l ocomotive, such as a diesel loconotive, to do ·,1ork ,mich an electric locomotive could do just as m,ll, und the roeuJ.ations imposed by the State of tJe,·1 York looked very much like a second edition of the Ten Cornmandmcmts, "Thou she.lt not 'i'hou shalt not - 11 all the nay through, and he thou..::;h'i:. men ·:;oultl not, r:ithout close supervie:i on, obey all those restrictions. I cl.so talked to !\fr,, Youne :fo.fety Engineer for the contractor, at one of t,he luncheons, and he told ~ that the first t~·: o years in puttin3 in the· diesels they �II 7 hn.tl <:- crreut deal of difficulty in oporatin•7 them. They l"equirecl much r~p~~r ,~·e rk, mm.~e <:lcse inopcction, chun~~ ti of lubricants, cleaninc 0 118 snubber rnruu.folcls, etc ., in order to insure good operation. . . In ~he afternoon of 'l'uesdcy, they had a pc.per on an investiga~~?ll o! b::i.turnnou~ coal dust suppression, tho pe.per dealing largely i::i.:th different met.hods of supplyin!,; vmte1• at t.he ,~-orkin3 faces for the cutter bar::;, for spray-lnt; the conl .

Son.e of the plans see.racd rather r.,rWtive. Soll',eonc asked the q1lcstion Yihy they did not put pipes in' tho mines, and they made the rotort thet it \'lao .till.Ch too expensive. I :·;as not impresaed by this . paper, c.s lt seemed they were going to a. great <leo.l of exoense to furnish a totally inadequate supply of i'ratcr at the \/orkin6 f aces· to control the dust. The paper also discussec.l. to so.:ie eJ....-tent t he use of chcr.ri.co.ls for ·c.his purpo~e, but the general consensuc seer.!<..-'<t to be this r:a.s c:uitc an expenoive nothod of controlling <lust: but raieht he justified ·.•:her e nater nas s carce, and th,:i.t sec:r.ted to be the ca se in most of the imtancoc which this Pc!.!JCI· cited.

I think L:r . llcl<enna gave a very good picture of the operation of shuttle cars, but he :::tressed the fact that much dust was made by their operation. In ta.lkin.~ regarding ventilation, he stressed very stron~ly doors on panels·, .-ihich are, of course, quite applicable to this method of workin3.

(Assorted if desired.) �SELECTED BIBLIOGRAPHY of ENGINEERING SUBJECTS Foreword This Selected Bibliography of Engineering Subjects has been prepared primarily for those who wish to continue study in engineering and allied fields and perhaps start building their own private librar ies. In prepar ing it, more than one hundred teachers of technical subjects and professional engineers wer e consulted, and the final selections are, of necessity, a compromise between several recommendations. Originally it was planned to make separate lists of elementary, intermediate, and advanced books in the various branches of engineering, but this proved to be impracticable. The Bibliography represents, therefore, a list of books mostly of college grade, with annotations to indicate the nature and depth of subject matter. I t is published in five sections and will undergo revsion from time to rime in order to improve the present lists and co include notable future publications. Section I Mathematics, Mechanics, and Physics Section II Aeronautical and Civil Engineering Section III Chemical and Industrial Engineering Section IV Electrical and Mechanical Engineering Section V Metallurgical and Mining Engineering There is little need to emphasize to young engineers the desirability o f reading continuously the current publications of their professional societies and other techrucal journals in addition to their fundamental studies.
