Attheendof48hourshisvesselwouldseemtohavebeenstillwellupandgoingstrong。TheonlyotherpreviousvoyagethathadindurationoftravelapproachedthisrecordwasthatmadebyM。Mallet,in1892,andmaintainedfor36hours。NextwemaymentionthatofM。Herve,in1886,occupying241/2hours,whichfeat,however,wasalmostequalledbythegreatLeipzigballoonin1897,which,witheightpeopleinthecar,remainedupfor241/4hours,anddidnottouchearthtill1,032mileshadbeentraversed。

Intheautumnof1898theaeronauticalworldwasinterestedtohearthatayoungBrazilian,M。SantosDumont,hadcompletedasomewhatnoveldirigibleballoon,cylindricalinshape,withconicalends,83feetlongby12feetindiameter,holding6,500cubicfeetofgas,andhavingasmallcompensatingballoonof880cubicfeetcapacity。Foranetwassubstitutedasimplecontrivance,consistingoftwosidepockets,runningthelengthoftheballoon,andcontainingbattensofwood,towhichwereaffixedthesuspensioncords,bandsbeingalsosewnovertheupperpartoftheballoonconnectingthetwopockets。

Theinventorascendedinthisballoon,inflatedwithpurehydrogen,fromtheJardind’Acclimatation,Paris,andcircledseveraltimesroundthelargecaptiveballoonintheGardens,afterwhich,movingtowardstheBoisdeBoulogne,hemadeseveralsweepsof100yardsradius。Thenthepumpofthecompensatorcausedtheenginetostop,andthemachine,partiallycollapsing,felltotheground。SantosDumontwassomewhatshaken,butannouncedhisintentionofmakingothertrials。Inthisboldandsuccessfulattempttherewasclearindicationofafreshphaseintheconstructionoftheairship,consistinginthehappyadoptionofthemoderntypeofpetroleummotor。Twootherhyingmachineswereheardofaboutthisdate,onebyProfessorGiampietre,ofPavia,cigar—shaped,drivenbyscrews,andriggedwithmastsandsails。Theother,whichhadbeenconstructedandtestedinstrictprivacy,wastheinventionofaFrenchengineer,M。Ader,andwasimaginedtoimitatetheessentialstructureofabird。Twosteammotorsof20—horsepowersuppliedthepower。Itwasstartedbybeingrunonthegroundonsmallwheelsattachedtoit,anditwasclaimedthatbeforeabreakdownoccurredthemachinehadactuallyraiseditselfintotheair。 OfSantosDumonttheworldwaspresentlytoknowmore,andthesamemustbesaidofanotherinventor,Dr。Barton,ofBeckenham,whoshortlycompletedanairshipmodelcarryingaeroplanesandoperatedbyclockwork。Inanearlyexperimentthismodeltravelledfourmilesintwenty—threeminutes。 Butanotherairship,atrueleviathan,hadbeengrowingintostatelyandgracefulproportionsontheshoresoftheBodenzeeinWurtemberg,andwasalreadyontheeveofcompletion。CountZeppelin,alieut。—generalintheGermanArmy,whohadseenserviceintheFranco—GermanWar,hadforsomeyearsdevotedhisfortuneandenergytothepracticalstudyofaerialnavigation,andhadprosecutedexperimentsonalargescale。 Eventually,havingformedacompanywithalargecapital,hewasenabledtoconstructanairshipwhichinsizehasbeencomparedtoaBritishman—of—war。Cigar—shaped,itslengthwasnolessthan420feet,anddiameter40feet,whileitsweightamountedtonomorethan7,250lbs。Theframework,whichforlightnesshadbeenmadeofaluminium,was,withtheobjectofpreventingallthegascollectingatoneendofitselongatedform,subdividedintoseventeencompartments,eachofthesecompartmentscontainingacompletelyfittedgasballoon,madeofoiledcottonandmarvellouslygastight。Asteeringapparatuswasplacedbothforeandaft,andatasafedistancebelowthemainstructurewerefixed,alsoforwardandaft,onaluminiumplatforms,twoDaimlermotorenginesof16—horsepower,workingaluminiumpropellersoffourbladesattherateof1,000revolutionsaminute。Finally,firmlyattachedtotheinnerframeworkbyrodsofaluminium,weretwocarsofthesamemetal,furnishedwithbufferspringstobreaktheforceofafall。Thetrialtripwasnotmadetillthesummerfollowing——June,1900——and,inthemeanwhile,experimentshadgoneforwardwithanothermodeofflight,terminating,unhappily,inthedeathofoneofthemostexpertandingeniousofmechanicalaeronauts。 Mr。PercyS。Pilcher,nowthirty—threeyearsofage,havingreceivedhisearlytrainingintheNavy,retiredfromtheServicetobecomeacivilengineer,andhadbeenforsometimeapartnerinthefirmofWilsonandPilcher。Forfourorfiveyearshehadbeenexperimentinginsoaringflight,usingaLilienthalmachine,whichheimprovedtosuithisownmethods。

ThisautumndiedGastonTissandier,attheageoffifty—six;

ThegreattrainoftheNovembermeteors,knownastheLeonids,whichatregularperiodsofthirty—threeyearshadinthepastencounteredtheearth’satmosphere,wasdue,andover—due。Thecauseofthis,andoftheirfinallyeludingobservation,needonlybeverybrieflytouchedonhere。Theactualmeteorictrainisknowntotravelinanelongatedellipse,thefarendofwhichliesneartheconfinesofthesolarsystem,whileatapointnearthehitherendtheearth’sorbitrunsslantinglyathwartit,forming,asitwere,alevelcrossingcommontothetwoorbits,theearthtakingsomefiveorsixhoursintransit。

Theshower,whichwaswellseenin1866,wasprettyconfidentlyexpectedin1899,andtoguardagainstthemischanceofcloudyweather,itwasarrangedthatthewritershould,onbehalfoftheTimesnewspaper,makeanascentontherightnighttosecureobservations。Moreover,itwasarrangedthatheshouldhave,aschiefassistant,hisowndaughter,anenthusiasticladyaeronaut,whohadalsotakenpartinpreviousastronomicalwork。

Thissettledthematterfromtheastronomicalside,buttherewastheaeronauticalsidealsotobeconsidered。Aballoonof56,000cubicfeetcapacitywasthelargestavailablefortheoccasion,andanightascentwiththreepassengersandinstrumentswouldneedplentyofliftingpowertomeetchanceemergencies。Thusitseemedthatapossibledelayofforty—eighthoursmightentailagreaterleakageofgasthancouldbeafforded。 Theleakagemightbeexpectedchieflytooccuratthevalveintheheadoftheballoon,itbeingextremelydifficulttorenderanyformofmechanicalvalvegastight,howevercarefullyitsjointsbestoppedwithluting。Onthisaccount,therefore,itwasdeterminedthattheballoonshouldbefittedwithwhatisknownasasolidorrendingvalve,consistingsimplyofballoonfabrictiedhardandfastovertheentireupperoutlet,afterthefashionofajampotcover。Theoutletitselfwasagapingholeofover2feetacross;butbythetimeitscoveringhadbeencarefullyvarnishedoverallleakagewassufficientlyprevented,theonedrawbacktothismethodbeingthefactthattheliberationofgasnowadmittedofnoregulation。Pullingthevalvelinewouldsimplymeanopeningtheentirewideaperture,whichcouldinnowaybeclosedagain。

Butthechillinessdidnotlastforlong。Aheightof1,500
