THE SEMI-WEEKLY TRIBUNE, NORTH PLATTE, NEBRASKA. Rqhiinq ilie Deadly Sea mie and I miamw: Human ingenuity has been taxed the limit in developing these instru ments of destruction and finding means to overcome them 0?l mnny months nftcr tho out break of tlio wnr obroad tho sub marine mine mus n close second to tlio torpedo In achieving tho do Htructlon of alt kinds of shipping. Thereafter tho mine fell Honiowhnt behind, not bccauHO It lacked power to do hnrm, but for two 4 other rensons first, tho wholcsomo dread Inspired by tho prescribed mined areas and next bocauso of tho various expedients adopted by tho belligerents to neutralize thofio subaqueous weapons. Even so, the mine Is playing u big part in marine warfare, and wo shall havo to count with It and against It now thnt wo have Joined forces with tho entente allies. It Is a mnttor of record that tho Germans got tho Jump on tho British by their prompt and oven daring employment of tho submarino mine. With in n very short tlmo nfter tho declaration of war Teuton mlno planters were operating on tho Eng lish and Scottish coasts nnd were busily engaged In sowing theso weapons at tho very entrance of enemy ports nnd rivers. For this purposo It was rather easy then to hnvo recourse to North sea Ashing crafi that had nil tho outward complexion of Tnnoconco; Indeed, for weeks theso boats went about their work well nigh unsuspected. It was only when British battlo craft wero mysteriously damnged and sunk that tho British authorities nwokened to their peril. Even ttyen tho belief prevailed that the damago was mqre or less a matter of sheer chance ' chanco In tho nnturo of n friendly defense mlno that had got adrift. Then tho next explanation was that n particularly daring U-boat commnndor had managed to got within striking distance, nnd finally It dawned upon tho British const patrol that enemy mines wero being freely planted right under their vory nosos. Every fishing boat was then an object of sus picion, nnd prompt Investigation proved In n great many cases thnt thero was nmplo warrant for this attitude. Neutral trawlers became moro nnd moro infrequent In certain of tho waters contiguous to tho north nnd east coasts of Scotland and Eng land, nnd for a tlmo tho mlno mouaco was held pretty well In hand. ' Tho resourceful Teutons, howovor, wero not checkmated, nnd It was only n question of tlmo be fore they dovoloped n method with which to offset tho vtgilnnco of tho British constal patrol. Then tho Gorman submnrlno mlno layers got to work, How many of theso tho kaiser's experts havo built nnd sent to their fields of scrvlco iu tho wntcrs of tho North oca especially, Is not known. It Is safo to. say too many of them hnvo boon built nnd dis patched upon their missions nnd tho general char acter of them nil is probably much akin to that of tho U-O-5, which was cuptured and taken Into a British port. By chance n British destroyer discovered tho U-O-fi on tho Burfnco nnd In distress at soma point along tho east const. When summoned by mega phone to surrender tho crew of tho submarine mustered on deck nnd held up their hands In token of submission, but curiously beforo n relief boat could bo sent to them they Jumped ovcrbonrd. f Tho couso of their action was soon explained. Another member of tho submarine's complement suddenly appeared upon deck nnd throw himself Into tho water and nlmost Immediately afterward thoro wero n number of violent explosions within tho U-0-C. Tho Inst man had exploded bombs which blow holes In tho craft. But for prompt action on tho part of n British sublleutonnnt, who, protected by a gns mnsk, went dnuntlessly down Into tho Injured U-boat, tho mlno planter would hnvo filled nnd gono to tho bottom In water too deep for her recovory. , As It was, sho represented a despernto task for lier would-be- salvors and It was neccssnry to so roX"couplo of mines within tho boat that had boon set freo by tho explosions beforo it was snfo to tow tho submnrlno Into harbor nnd to dork her. Upon, examination this now order of sub mnrlno was found to bo charged or laden with n dozen powerful contnet mines housed In six vor tical wells passing directly from deck to bottom of tho crnft. Each woN held two mines, ono on top of tho other, nnd both woro Sept In their plnccs by lock ing devices which could bo released from within (ho submarine, Tho controlling stntlon for this operation was found to bo In tho conning tower, so thnt tho commander of tho boat with only her periscopes nbovo water could Beo Just whero to sow his weapons. In this way tho Germans havo been able upon mnny occasions to approach certain sections of the waters about tho British Isles nnd to plant there mines thnt havo accomplished tho destruc tive work cut out for them. How many ships liayo been sent to tho bottom by mines sown by boats of this sort Is, of course, a mntter of con jecture, but thero can bo no doubt that submarino mine planters nro nctlvely employed todny. Ono thing nbout them thnt makes them of spe cial Merest, oven concern, to us Is thnt thero Is noUilng to prevent their operating In n similar manner upon our Atlantic coast, What Is to pro vent n submarino somewhat after the order of tho Deutschlnnd from being equipped for work of this nnturo? Instead Qf carrying some hundreds of tons of commercial freight she cpuld Just as easily Vldo that weight among mines, mlno-plnnt- - 'tS .41. Ing apparatus and an Increased supply of fuel nnd food which would mnko It possible for her to per form her service for longer periods and over wider zones of action. Tho wholo subject of submnrlno mines, offensive and defensive, and tho subaqueous protection against enemy submarines Is ono with which our naval nnd military authorities are deeply engaged. It Is safo to sny that we are going to sco some re markablo developments, and largely becauso our allies are going to give us tho benefit of their own experience so thnt native Ingenuity can start to Improve upon tho fruits of the labors of others. Indeed, our subaqueous defenses must of necessity bo of tho best types possible because of the extent of our seaboard and "tho comparatively limited number of vessels thnt tho navy has for patrol work. Tho recent presidential order prescribing de fenso zones nt tho approaches of certain ports and waterways had to do with tho army's part pri marily In this matter oC subaqueous safeguards. Tho mlno fields controlled by tho military authori ties, those of tho Const Artillery corps, are ns n rule protected by observotlon mines or electric contnet mines that nro mado active or lnnctlvo by tho oporatlon of a switch. That Is to say, the vita lizing current comes from n central station ashore, and neither of theso types of mines will explode unless tho electric current reaches them by way of n submerged cnblp. In tho case of tho contnet mlno with tho current turned on tho mlno will explodo when bumped and tilted over to a prescribed nnglo. Tho obser vation mine, on tho other hand, does not hnvo to be touched by tho enemy craft, but Is subject to tho will of nn observer on shore. Observation mlnos nro planted In groups nnd nro Inid out In definite checkerboard nrcas, and ench group Is set off separately and simultane ously, Tho observer, by means of range marks -or benrlngs, knows Just when tho approaching foo renches any ono of theso squares, and accordingly tho ono within which the enemy lies at tho mo ment determines tho group of mines to bo deto nated. Tho contnet mlno, ns may enslly bo understood, does Its work whero nn observer might fnll, after dark, and for that reason the electric current Is turned on with set of sun nnd tho wholo nrea so sown becomes Instnntly n menned to friend or foo. H Is quite likely thnt observation mines wero employed by tho Turks nt tho Dardanelles, nnd thercforo by npproachtng from under water It was possible for tho British submnrlno B-31 to dlvo beneath five rows of mines, probably shoving their cables aside and tilting tho weapons, and then pushing on so thnt sho could rlso to the sur faco nnd torpedo tho Turkish battleship afessu dlyeh, which was stationed to guard thnt very mlno field. Had those mines been of tho contnet sort, tho displacement of their cables would probably havo caused their detonation nnd likewise tho destruc tion of the B-ll. Other British submarines suc ceeded In passing submerged through thoso Turk ish defenses, the enemy observers being unnblo to see tho underwater boats. It was tho exploits of tho submarines nt tho Dardanelles thnt disclosed to tho British tho weak spot In their own mlno defenses nnd led u short while afterward to tho development of other protecllvo agencies In deal ing with tho German underwater boats. Unquestionably tho most speetncular part- of submarino mining Is that In which tho weapons aro resorted to In open waters, especially In thoso offshore ureas whero a defense of thnt sort Is not ordinarily employed. Tho Itnllans were tho plo neers In this order of subnqueous warfare, and they developed tho art In penco to such a point thnt other nations realized thnt tho mlno was no longer limited In Its potential usefulness either to the defenso of a port or for blockndlng the ships In nn enemy harbor. The Italians showed that tho submnrlno mines could he used offensively, so to speak, If planted secretly and placed whero by strategy tho unsus pecting foo could bo lured over and Into them. Tho Jupnneso during their war with Bussla made good use of what tho Italians had taught them, nnd when tho present conflict began Germany was fully propnred to carry the practlco still fur ther. German mine lnyors wero ready and numerous on August 1 three years ngo; and as wo now know the kaiser's navy lost no time In mining tho murine nppronehes to tho fatherland. Not only that, but those craft, In various guises, planted mines over wide areas In the North sen and In tho waters of (he British Isles. Tho Haguo convention of 1007 among other things provided that "It Is forbidden to lay nn chnrod automatic contact mines which do not become harmless ns soon ns they havo broken loose from their moorings;" nd It was also prescribed (lT-or-CKDENARV -t People f HA8 DUTY OF PROTECTING SOLDIERS Drink nnd Immorality have been tho bane of the soldiers' camps In all countries. At times ns mnny ns one fourth of tho enrollment havo been In tho clutch of one or tho other. In Europe, during tho present wnr, tho ravages of disease nnd the effects of Inebriety have been so extensive nt times that tho most stringent rcguln tlons havo been established. But In tho mnln tho measures adopted havo been repressive and curative nfter tho fact. The attack on tho enmp evils was not begun until their inroads made notion imperative. In the United States tho problem of camp evils Is to bo attacked In a way and on a scale nover undertaken In the world before. Greatest empha sis Is to be placed on prevention, on effective action before the fact, in stead of after it. To achieve this, to evolve a new kind of soldiers' train ing camp, Is the task of the newly nn- polntcd federal commission on training camp activities, with Raymond B. Fos dlck at Its head. Already this work has begun, with tho opening of the train ing enmps for the preliminary officers' training corps. Immediately around tho camps will bo zones, according to the plans of tho commission, to bar out Infections nnd alcoholic excess, but tho aim will be, In following out the later principles of phychology, to withdraw, so far ns possible, the nttcntlon of the soldier from the rigid restrictions of the zones by the orgnnlzcd presentation of better means of recreation and enjoyment. at that time WCMW that no unnnchor- Of C&ZfTMrJZmi7- cd mines should bo used which would bo dungeroust moro thun an hour nfter they had been dropped Into tho sen. Tho mines In question are self-contained contact mines that arc not controlled from any shore or observing stntlon nnd nro well-nigh Instantly men acing when cast overboard. Just beforo tho war the Germans, with their usual technical cunnings, developed a naval of fense nnd defense mine which could be used clthev In a fixed position or bo planted hantlly la water traversed-by enemy shipping. This mlno is tho typo which has done such destructive work nnd Is designed to be fired by nn electric battery placed Inside of the mine, this battery being Inactive un til tho mine has been submerged nnd then struck by n pnssjng craft. A development of tho contnet mine which the Germans have at times employed successfully Is ono surmounted by n dummy or decoy periscope. Tho object of this ruse Is to invito ramming on the pnrt of a patrolling vessel or even a mer chantman when the deceived navigator believes that the- chance Is good for sending n U-boat to tho bottom. Of course n vessel attempting to rnm that dummy periscope Is sure to strike tho con tact mlnolind cause It to explode, the result being disastrous to the ramming craft. This luro has not worked so well latterly bo cause tho observer Is able In n few moments to establish tlio'fnct that tho pcrlscopo Is statlonnry, and tho work of getting the underlying mine out of the wny is left to tho fairly safe process of sweeping trawlers linked together by a loop oj! wlro rope doing tho work. In order to denl with both tho submarine tor pedo bont nnd the submnrlno mine planter the British admiralty has had recourse to defenso nets of n novel character. Theso have "been very well described by Rear Admiral William S. Sims. According to this authority: V "Wo did not find out for a long tlmo what thoso nets are like and I think It Is necessary that it should be understood In order to renllzo tho great danger submarines run In tho presenco of light surface craft. "The net is a very light one, mado of little wire rope, probably not as big ns a lead pencil, prob ably not moro than a quarter of an Inch In diame ter. Tho meshes of tho not nro 12 to 15 feet square. On top of this net nro floats nnd on the bottom nro little weights. "Tho moment this net 'unbeknownst to tho submnrlno commander, of cours(! Is In tho water In front of him, tho floats keep the net on the surface and tho weights keep tho bottom down, and if ho runs Into It his bow goes into ono of tho meshes nnd tho net falls back around hlra, and It mny foul his propeller or may not "The net Is 800 or 400 yards long, and ns tho submarine proceeds tho floats will trail on tho surface, so that even if ho dives deeper he leaves theso on tho surface nnd his trail Is plain and thero Is no dllllculty then. In capturing him. Ho knows when he runs Into a net that his capture Is prae tlcally certain. If ho goes down 200 feet tho floats of tho not are still on the surfnee." Theso nets aro used In two ways, either passive ly ut chosen points In guarded waters or they are dropped overboard by patrolling vessels thnt dis cover n submerged submnrlno In motion. It is a fact that oven though u submarine bo running totally submerged 20 or 30 feet down, It still entities a disturbance nt tho surface, not n wake In the usunl sense of 'the term, but a typo of wave which Is easily distinguished from the regu lar surface waves, tind this phenomenon Is readily discernible from tho brlago of a ship or from a hydroplane. To return to the submarino mine. We hnvo so far considered only thnt so-called offensive typo which can bo anchored In fairly smooth wnters such as prevail extensively In tho North sen, but now let us tako up that kind which can bo dropped ovorbonrd In much deeper water. This sort Is capable of being planted from a speedy ship seemingly bent upon escaping from her pursuers nnd her strategy consists In Inviting chnso while dropping theso stumbL'ngblocks right In tho path of her oncoming enemies. Generally tho ship hitting weapons of this sort does so bow on, and that part of a vessel Is the least vital section. A craft may. hnvo her. how blown off nnd yet bo nblc to make n haven, and besides tho damage may po susccptlblo of speedy repair. Our mines, on tho bther hand, have a de layed action, nnd uf tor belnjf hit by the stem of a craft roil sternwnru intontnct with her hot torn for some distance before they explodo. In this way tho blow, when tho mlno docs burst. strikes some vital area urn! tho dnmnge Is well nigh certain to be fatal. New York Sun. MASTER OF TRANSPORTATION iium urn mi iihwimiwihiimiii Samuel M. Fclton, president of the Chicago Great Western railway, has been selected to take charge of ar rangements for sending the regiments of American railroad men to France. Mr. Felton some time ngo wns ap pointed adviser to the chief of army engineers in relation to railroad af fulrs. As such, it wns said, he will bo In charge of arrangements for sending the American railroad men abroad. It Is understood that Mr. Feltou will not necessarily nccompany the forces. The plan Is to send 10,000 skilled men to operate and maintain tho French roads behind tho battle lines. They need reconstruction and expert Qperatlon, for which tho French mili tary forces cannot spure their own men. Regarding theso plans Mr. Fel ton declined to make any extended statement. "Thero is nothing more that can be said, and nothing thnt will be said. It is to tho interest of all concerned that no details be printed." One report hnd it that Mr. Feltou had been appointed by the council of nntlonul defense. That Is Incorrect. He was aiding the government beforo the council of national defense came Into existence. He was selected by the secretary of war when the Mexican troublo started as adviser to the army engineers in transportation and railroading. GIVES SERVICE TO RED CROSS Robert S. Lovett, chairman of tlio board of the Union .Pacific railroad, has volunteered "the whole of his time during the war to any work to which ho might be assigned," by tho American Red Cross. In a letter to Henry P. Davison, chairman of the war council of the Red Cross, Mr. Lov ett said ho was "too old to go to the front," but wns anxious to do his "bit" in whatever manner lie could be made useful. Accordingly, Mr. Dnvlson asked him to come to Washington for a con ference preliminary to the formation of a committee to prevent duplication nnd waste In all activities of relief and alleviation resulting from tho wnr. Ho also was asked to accept ttie chair manship of this committee. Others requested to Join Mr. Lov ett at tho conference in Washington, nccordlng to Mr. Davison, are Rt. Rev. Charles H. Brent, Protestant Episco pal bishop of tho Philippines; A. D. Hoderpyl of Grand Rapids, Mich.; George Wharton Pepper of Philadelphia; Edward D. Butler of Chicago, and John F. Moors of Boston. "It is singularly In keeping with tho stupendous things which the Red Cross Is already being called upon to do, and Is planning to do, not only to relieving sufferings, but to help win tills wnr, that big men of affairs like Mr. Lovett should feel It to bo worth their while to plnce themselves thus un reservedly nt tho nation's service," said Mr. Dnvlson. HIS TASK TO TRAIN OFFICERS Without nny thought of even sug gesting a comparison that might bo odious to -the thoroughly trained ofll cers of the United States regular army and with full appreciation of tho fact that threo months of drill and In struction can never produce the re sults of four years of hard work In what Joffro has called the greatest military school In tho world, It may still be sold thot the country now has 10 new military schools working full blnst for tho manufacture of person nel to officer tho great nrmy that will bo evolved out of the selectlvo drafts by the end of tho summer. They might bo called new West Points to tho extent that tho officers of tho army who have planned them, nnd who are managing them, uro determined that tho spirit of these great camps shnll bo the spirit of tho academy on tho Hudson. 41 Til nnv nttimin qunlltles of these young men in the training camps," said Brig. Gen. H P McCain, adjutant general of tho army, "we must remember that the 40000 enrolled were selected from 200,000 who applied for enrollment. And this very carefully selected raw material Is to bo subjected to the severe test of threo months of experience and Instruction to the tune of something over 47 hours of hnrd work a weck,wltu nil the work and all the leisure under Rtrir uiiUtury dlclpllue." irKl
