The brief period from 18RG to 1S38 will, perhaps, In coining nges, bo bet trained for tlio extremely rapid ad vancement made In modern explosives. This epoch-making span of time nny perhaps be further expanded, for the new science Is yet In nn experimental stage. There may bo discoveries In this near future ns remarkable and mo mentous ns those of the past decade and u half. If to, this period will bo doubly rotnembered. Explosives are necessarily destructive, and their devel opment Implies the acquisition of new and terrible power. The application of this science marks the bolder lino be tween nnclent mid modern times. Explosion has been defined as the ex tremely rapid conversion of solid or liquid substances Into ga3 or vapor, occupying many times the volume of the original body. This gas Is further expanded by the heat generated dur ing the transformation. Any sub stance that is capable of undcrglng the above nictnmot phosls Is termed an ex plosive. GK11M OF Tim DISCOVERY. The germ of the science of explosives lay in the accidental discovery of the peculiar properties of saltpeter, which Is found plentifully scatteied In nature tipnn the surface of the plains of In dia and of China. Knowledge of its deflagrating qualities could not well be avoided after the use of tiro upon those vast Asiatic stretches of land, for by means of the chaired embers of wood II res used for cooking, the two most Important ingredients of gunpowder could easily have been brought Into contact with each other. The acci dental dropping of crude saltpeter tip on coals of lire would have been fol lowed by prolonged and accelerated combustion. Without any known facts to rely upon, historians generally agree that In some such way the beginnings ol the hlstoiy of explosives were In augurated. Sulphur was doubtless an efter addition, not necessary to cause CMi'.csIon. tlack powder, from tho time of Its Introduction Into Europe, has always consisted of saltpeter, charcoal and sulphur In various proportions An ex cess of charcoal quickens combustion, an excess of saltpeter slackens It. Tho propulsion force depends chlelly on tho late of combustion and the volume of gas produced, aijlng with tho pio portlons of the mixture. Gunpowder gas litis about 300 times the space occupied by the solid powder. A CENTURY AGO. If the ingredients of black gunpow der have romalne I the same for many ccntuiics It Is not because numeious experiments were not made to improve its composition by adding other mih btaiKe.. In 1784 Baieelo made vailous attemi te to change the composition, and he hud many follow oik Inventors ur? still working nt tl e pioblem. Tho (distinction of modem guns has mnd Imperative some modifications in the foim and enVcls of tho explosive ui-d A slow -binning powder was needed, which would burn in inci easing litioand develop its maximum sttcngth Jint when the hhot toadied the muz-zl- of the gi-n Germany took the In itiative in thlb direction in IS?.', when a slow -1 in nln.T powder was pioduced in thrt country c tiled cocoa powder, be cause in enjor it ic-embled a cake of chocolate. The method of mnnufnc tuie was kept secret, I ut other coun tries pjocuied samples of the powder, analyzed It nnd boon Wined to make a better substitute. This German co coa powder differed from black gun powder malnl.v by changing the pio-portlom- of the Ingredients to 70 per cent, saltpeter, 18 per cent, charcoal and 3 per cent sulphur, nnd by living nn mulerlurnt charcoal, which gave it the peculiar colot. For this blown powder charcoal made from lye itraw was also used. Vnrlous shapes hive been adopted for tho blown powder, now used by all countilcs for heavy ordnance, and ex cellent results have followed the use of hexagonal pilsmatlc grains pierced by small holes tluougli which tho flames pass, burning fiom the center outwaid and constantly evolving more gas till combustion is completed. FOP. J,ARGE GUNS. It Is well known that for many years the imptovement of powdcis for large gunB hn.s not kept pace with the manu facture of the gun Itself. Tho secre tary of tho United States navy two years ago called attention to the diffi culty of ohiulnlng in bufflclent quan tities for actual service a high giado brown powder for large guns, nor was it assured that these povvdei3 would onduio tho test of long storage. It has been found that the efllclency of brown powder varies logulurly with tho weather, requiring 3 per cent, more in midwinter and 3 per cent, less in mid summer than in srilng or nutumn. It Is now quite generally believed by naval and ir.llltaiy experts that gun powder Is rapidly passing uway ns an effective nnd standaid explosive. Oth er modem explosives hnve, during tho past twelve eais, lieen substituted to fruch nn extent that to ictiirn to gun powder seem.! impotsible. Tho substi tutes hive not pased tho pcilods of probation, but changes in firearms have compelled the revolution In explo sives. The invention of rupld-ililng guns made neccssaiy tho use of n smokeless powder. The illle of smaller caliber demanded nn explosive of greater force. Whllo theso experiments were pro gressing In Englnnd, Franco and Ger many, Alfred Nobd formed tho. Idea of reducing tho rate of combustion in his blasting gelatin by Increasing tho peioentage of gun cotton, In order that it might bo used as u substitute for gunpowder. This led to the patent ing of a smokeless powder in 1SSS culled balllstlte, which ho introduced in the Italian army and which wns also edopted by Get many. As now manu factured balllstlte consists of fifty parts soluble nltro cellulose and iifty parts nitroglycerin. Its uso has been dis continued by Germany, but it is still in favor In Iluly. It has been conted Wth graphite to pi event fj-.o exuda tions of the nlttoflyccrln. Two modern explosives nio at the base of all these substances for gun powdergun cotton nnd nitroglycerine. The so-called nltro compounds were first discovered in 1832, when Bracount of Nancy found that statch, wood fib era and similar substances would eas ily yield a combustible substance, which "Samter's" Greatest Clearing Sale of the Season Never were such prices known in the history of this or any other store.

DisrovnitY of ai'N cotton. In 1843 Schnbcln of rtalo discovered thut cDtton could bo cons ei ted into u highly explosive body without alter ing its structure, by treating it with nltito acid. Tho same dlscoeiy was nmde independently the le.ir follow -Ini, b; Hottger of Frankfort-on-the-Miiir.. Both inventors tried to hell tho pccict to tho German union, but tho union would make tho purchase only on condition that tho new explosive possessed an advantage over gun powder. Other nations heard of It, and throughout Kuropo many experiments wcie made with a slew of substituting cun cotton for gunpowder. Nitroplycerlne was discovered In 1S10 by hobrero, professor of chemistry at Turin, but the discovery remained un developed for many yeais. In 1S63 Al fied Nobel, the noted Swedish chemist, Invented dynamite by mixing liquid nilioflycerlne with a highly poious In fuslc nnl ctuth. He also, in 1S78, in- ented gelatin and other explosives for blasting purposes. Dynamite Is iibed for civil and gun cotton for military operations, Numeious other explosives luive appeared in recent years, but most of them have disappeared after a bilcf and unsuccessful tilal, Plata acid has been known for many years, In 1S67 potassium plcrate wus used in America and in Kngland as a charge for bombs. In 1887 the French govern ment introduced picric acid us inelln lt. Austria was tho first country to en gage elaborately In the attempted sub stitution of cun cotton for sunpowder. A factory was elected at Illrtenberg In IS,,", and tho explosive was Intioduced In some special artillery. But It was frund that tho guns were attacked by the gases and that tho high pleasures injured the battels. It was then de cided to use the new explosive only In lilting shells and In toipcdocs. Theio wore two tcrilflc explosions in tho Illr tenberg magazines In 186.' and 1S63, and after the second disaster tho manufae tute of gun cotton ceased In Austria until 1S7S. hi;voi.utionizi:d WArtFAitc. Between the years 1SG4 and 1888 tho initial stages wete completed which weto destined to tevolutlonlze modern watfate. In the former year V. dchultzo nf rotsdam began the nianufactuip of gunpowder fiom nitrated wood. In 1805 Sir Ficdetkk Abel, chemist of the British war department, patentol a ptoeess for putlfylug gun cotton, re ducing it to a lino powder by bcatlu,; maihlncs and then presblug It. That process is now generally used, in 1SSS Vlello, tho celebrated chemist of tho Ftench gunpowder works, discovered a means of making smokeless gunpowder fiom gun cotton dissolved In sulphuric ether mixed with picric ncld. SSIOKULUSS POAVDIUt. Sir Frederick Abel and 1'iofessor James Dewar, members of the English comnilttco on explosives, Invented a smokeless powder consisting of a com bination of the highest nltiated cellu lose with nitroglycerin by dissolving both in ncetone. It was Introduced in to the English service as cordite, for use with small arms nnd guns of all callbi.es. It Is now composed of nit roglycerin, ilfty-cight purts; gun cot ton, thirty-seven parts and mineral Jelly, nvo parts. Cordite piovcs stable under cxttcme conditions arIn;; trom the arctic cold of Canada to the ttop ic.il heat of India, nnd icslsts c.xposuio to moisture of nil kinds. Its effects on the boie of guns Is a serious dlfll culty. It eiodes tho gun to such an, extent ns to suggest Its abandonment. The I'nlted States naval smokeless powder Is a nltio ccllulotc powder con sisting of a mixture of Insoluble nnd solublo nltio cellulose, to which is ad ded the nitrates of barium and potass ium and a small percentage of cal cium carbonate. The proportions for G-lnch lapld-ilie guns are mixed nltro cellulose, eight paits; barium nitrate llfteen parts: potassium nitrate, four parts, nnd calcium carbonate, one part. The I'nlted Stnles war depjitment has been experimenting with vailous .types of smokeless gunpowder, atylng from an c nthe composition of gun cotton nnd no nitroglycerin to nbout -10 per cent nltioglycerln. The "VA" pow der, pioposed for fceislce In the United States for the uso of guns both in tho ni my nnd navy, consists of liiholublo gun cotton nnd iiltioglycerlu, with nn organic subhtanco as a deteirent or ic gulator. Like all smokeless gunpowder It exeits u deleterious effect upon tho bore of guns. 'a WO dJJNli.it Vi ASSES. In geneial, present f.. " less pow der i nro fif two genera, fies: First, Insoluble gun cotton or soluble nltro cotton, alono nr niiNfd with each other or with regulative substances, and, hciond, the nbovo with nltro. glycerin ndded. Smokeless powdeis derived from picric acid and other bubslnnces have been dlscaided. Among the essontlals pt smokeless powdcis are (.mokelessness, stability under varying conditions, safety In lmndllnz ur.d freedom from cases in jurious to guns or Inhalation. There nio none that comply with all these conditions. The combustion of smoke less powder Is usually complete, th l exulting gases buing chiefly cai Louie acid nnd steam. The nbove uns of the new explosives nio to weapons gieatly Impioved, It In Hue , lilch in some foim have been in use for ninny centuries. But tho i evolution wi ought by gun cotton nnd nltioglvcciln In waif.ue has nlso biourbt Into n high degree of efllclency new nnd tcrilble devices of destruction. Mines and toipcdocs were only germs during the; leglme of black gunpowder. The aro now most valuable adjuncts, especially In naval warfaie. and, in tho opinion of bomo expeits, have super bcded, or will boon Fiipeisede, gunnery In iclntlvo Importance. Both torpedoes nnd mines were tlrst used "in naval opeintlons In the war of the icbtlllor, durlrg which struggle twenty eight vessels weie blov n up by mines and ei by totpedoe. Theso de vices, deadly as lhey were at times, wcie usually of the crudest descrip tion. The mines weie often meiely vcodeu biurets lilted with gunpowder and llud by blow-burning funis. No In aver or moie daring naval deed in io lation to mines was perfoimed Ihan the part-age of Admiral Fnrragut's ileet through a. channel in the Mississippi liver known to bo nllvn with mines One ship, the Tecumsch, wns struck, but though desperate odds were against, him, the admiral ran tho gnuiit let fortunately without fuither loss. The cases of tho totpedoes scraped ugaltibt tliu copper bottoms of the ships, and In evvtal inttnitces the prime! s snapped audibly, but no more torpedoes exploded. Dullng the Frfiryco-Prusslan war tho French ileets did not enter Prussian harbors through fear of submarine dnngois The Japanese ileet at Ynlii did not hesitate to ntlick their enemy on tho open rea, but icfialned from following tho vessels up the ilvef. The hidden dangers wete held to be far greater than guns. The only way to ovetcomc the dangci of mines Is to de stioy thorn, ri blow nnd labotlous task for an cnemj. For offenhive opeiatlons In attack Ins Ileets on the open bca the toipedo is lecognlzcd as tho most effectlvo weapon. It Is a mnrvel of mechanical Ingenuity and petl'ecthm. TYPES OF TOltPEDOES, The Whitehead torpedo, the stand ard with most nations nt ptesent, was evolved In ISOt from the brnln of Cap tain I.upuls. nn Austtlan naval ollleer. It has since been gieatly impioved. It Is In appeal mice cigar-shaped, from fourteen to nineteen feet In length and fiom fourteen to nineteen Inches In di ameter at Its thickest point. Tho shell Is made of steel or phosphor-bronze. Within nio thieo compartments. In tho lltst is a heavy chaigo of gun cot ton. Tho second Is tho ulr lecelver, lllled with compressed nlr, while In the thlid nio-tho propelling engines nnd gulldlng mechanism. The Howell tor pedo, Invented by a United States naval ofllcer, Is not unliko tho 'White head In shupe, but Is dilvcn by means of n lly wheel contained In the shell. Besides this typo thete aro locomo tive oi dliiglble torpedoes, which, when llred, aio conti oiled fiom shoto by means of a tine cable, wound up In tho toipedo llko a lepl. The nuvy departments of most na tions have udopted compressed gun cotton both for submarine mines and I for torpedo charges. It 1ms been se lected ns the United States' service ex plosive. Experiments with gun cotum wete begun by Ptofessor Hill at tho United States toipedo station In 1872. Eleven eais ago the Hist gun cotton toipedo outllt was Issued to the I nlted States ship Tienton, the gun cotton being supplied in cyllndilcal disks thieo Inches In diameter and two inches high. The niauufaitutc of gun cotton, nnd of neai ly all nltro. compounds, consists of Immersing the cotton, glycol ino or other mntcilal In a mixture of nitrlo nnd siilphutlc acid for u long time. Tlio explosive body Is then lemoved fiom the spent ueid, washed and treat ed with alkalies till all trace of acidity is lost If n trace of acid remains spontaneous decomposition and often explosion occuis. Care must bo taken that the iiitton is perfectly pure. In the chemical le.iction water In the cel lulose is replaced by nitric acid, or hydiogeu by the nltro ginups. Gun cotton lias u much more powerful ef fect than black powder and burns without leaving any residue. In out waid appearnnce It differs only slightly fiom the ordinary cotton, but Is somo whnt daiker. Is harsher to the touch and gtntes slightly in squeezing. It Is also heavier than cotton. It Is safer to handle than dvnamltc, and ona pound gives in combustion nbout 22, 163 inches of gas and produces the ef fect of fiom four to six pounds of gun powder. Its prepaiatlon for service U a complicated piocess, and It Is made, in vailous shapes for various uses. In toipedoes gun cotton Is detonated by fulminate of mercuiy. which when Ignited by n blow expands to 'about 2, 6Q0 times Its own size. This sudden ex pansion gives a severe blow to the gun cotton nnd detonates It, Fulminate of mercury Is the chemical combination of mercury w 1th alcohol and nitric acid
