AfterMr。Coxwell’sexperimentsatAldershotin1862themilitaryballoon，asfarasEnglandwasconcerned，remainedinabeyanceforninelongyears，whentheGovernmentappointedaCommissiontoenquireintoitsutility，andtoconductfurtherexperiments。ThemembersofthiscommitteewereColonelNoble，R。E。，SirF。Abel，CaptainLee，R。E。，assistedbyCaptainElsdale，R。E。，andCaptain（nowColonel）Templer。Yetanothernineyears，however，elapsedbeforemuchmorewasheardofthismodernisedmilitaryengine。
ButaboutthebeginningoftheeightiestheGovernmenthadbecomefullyalivetotheimportanceofthesubject，andRoyalEngineersatWoolwichgrewbusywithballoonmanufactureandexperiment。Soon"theskyaroundLondonbecamespeckledwithballoons。"Themethodofmakingso—calledpurehydrogenbypassingsteamoverred—hotironwasfullytested，andforatimegainedfavour。Theapparatus，weighingsomethreetons，wascalculatedtobenotbeyondthecarryingpowersofthreeservicewaggons，whileitwascapableofgeneratingenoughgastoinflatetwoballoonsintwenty—fourhours，asingleinflationholdinggood，underfavourablecircumstances，foralongperiod。AttheBrightonVolunteerReviewof1880，CaptainTempler，withninemen，conductedtheoperationsofacaptivereconnoitringballoon。ThiswasinflatedattheLewesgasworks，andthentowedtwoandahalfmilesacrossariver，arailway，andalineoftelegraphwires，afterwhichitwasletuptoaheightof1，500feet，whence，itwasstated，thatsogoodaviewwasobtainedthat"everymanwasclearlyseen。"Beitremembered，however，thatthecountrywasnottheSouthAfricanveldt，andeverymanwasinthestrikingEnglishuniformofthatdate。
JustatthisjuncturecametheEgyptianWar，anditwillberecalledthatinthebeginningofthatwarballoonswereconspicuousbytheirabsence。Thedifficultiesofreconnaissancewerekeenlyfeltandcommentedon，andamongotherstatementswefindthefollowinginthewarintelligenceoftheTimes:——
"AsthewantofaballoonequipmenthasbeenmentionedinlettersfromEgypt，itmaybestatedthatalltheWarDepartmentballoonsremaininstoreattheRoyalDockyardatWoolwich，buthavebeenrecentlyexaminedandfoundperfectlyserviceable。"AnassertionhadbeenmadetotheeffectthatthenatureofthesandinEgyptwouldimpedethetransportoftheheavymaterialnecessaryforinflation。Atlast，however，theordercameforthedespatchoftheballoonequipmenttothefront，andthoughthisarrivedlongafterTel—el—Kebir，yetitisrecordedthatthefirstascentinrealactiveserviceintheBritishArmytookplaceonthe25thofMarch，1885，atSuakin，andballoonsbecomingregardedasanall—importantpartoftheequipmentofwar，theyweresentoutintheBechuanalandExpeditionunderSirCharlesWarren，thesupplyofgasbeingshippedtoCapeTownincylinders。
Itwasatthisperiodthat，accordingtoMr。Coxwell，LordWolseleymadeascentsathomeinawarballoontoformhisownpersonalopinionoftheircapabilities，and，expressingthisopiniontooneofhisstaff，saidthathadhebeenabletoemployballoonsintheearlierstagesoftheSoudancampaigntheaffairwouldnothavelastedasmanymonthsasitdidyears。Thisstatement，however，shouldbereadinconjunctionwithanotherofthesameofficerinthe"Soldier’sPocketBook，"that"inawindycountryballoonsareuseless。"IntheBoerWartheusefulnessoftheballoonwasfrequentlytested，moreparticularlyduringthesiegeofLadysmith，whenitwasdeemedofgreatvalueindirectingthefireoftheBritishartillery，andagaininBuller’sadvance，wheretheballooniscreditedwithhavinglocateda"death—trap"oftheenemyatSpionKop。Otherall—importantservicewasrenderedatMagersfontein。TheServiceballoonprincipallyusedwasmadeofgoldbeaters’skin，containingabout10，000cubicfeetofhydrogen，whichhadbeenproducedbytheactionofsulphuricacidonzinc，andcompressedinsteelcylinders。Aspecialgasfactorywas，forthepurposeofthecampaign，establishedatCapeTown。
ItisherethatreferencemustbemadetosomeofthespecialworkundertakenbyMr。EricS。Bruce，whichdealtwiththemanagementofcaptiveballoonsunderdifferentconditions，andwithasystemofsignallingthusrenderedfeasible。Mr。Bruce，who，sinceMajorBaden—Powell’sretirementfromtheoffice，hasdevotedhisbestenergiesassecretarytotheadvancementoftheBritishAeronauticalSociety，wastheinventorofthesystemofelectricballoonsignallingwhichhesuppliedtotheBritishGovernment，aswellastotheBelgianandItalianGovernments。Thissystemrequiresbutaverysmallballoon，madeofthreeorfourthicknessesofgoldbeaters’skin，measuringfrom7to10feetindiameter，andneedingonlytwoorthreegascylindersforinflation。Withintheballoon，whichissufficientlytranslucent，areplacedseveralincandescentlampsinmetalliccircuit，withasourceofelectricityontheground。Thissourceofelectricitymayconsistofbatteriesofmoderatesizeoraportablehanddynamo。Inthecircuitisplacedanapparatusformakingandbreakingcontactrapidly，andbyvaryingthedurationoftheflashesintheballoontelegraphicmessagesmaybeeasilytransmitted。Toovercomethedifficultyofunsteadiness，undercircumstancesofroughweather，inthecaptiveballoonwhichcarriedtheglowlamps，Mr。Bruceexperimentedwithguyropes，andgaveamostsuccessfulexhibitionoftheirefficiencybeforemilitaryexpertsatStamfordBridgegrounds，thoughastiffwindwasblowingatthetime。
Itmustbeperfectlyobvious，however，thatacaptiveballooninawindisgreatlyatadisadvantage，andtocounteractthis，attemptshavebeenmadeinthedirectionofacombinationbetweentheballoonandakite。ThisendeavourhasbeenattendedwithsomemeasureofsuccessintheGermanarmy。Mr。
DouglasArchibald，inEngland，wasoneofthefirsttoadvocatethekiteballoon。In1888hecalledattentiontotheunsatisfactorybehaviourofcaptiveballoonsinvariablewinds，droppingwitheverygustandrisingagainwithalull。InproofhedescribedanexpedientofMajorTempler’s，whereanattemptwasbeingmadetooperateaphotographiccamerahoistedbytwotandemkites。"Theballoon，"hewrites，"wentupmajestically，andallseemedverysatisfactoryuntilamileofcablehadbeenrunout，andthewinderlocked。"Itwasthenthattroublesbeganwhichthreatenedthewreckageoftheapparatus，andMr。Archibald，inconsequence，stronglyrecommendedakiteballoonatthattime。Twelveyearslaterthesameableexperimentalist，impressedwiththesplendidworkdonebykitesaloneformeteorologicalpurposesatleast，allowedthathewasquitecontentto"letthekiteballoongoby。"
ButtheGermanschoolofaeronautsweredoingbiggerthingsthanmakingtrialswithkiteballoons。TheGermanSocietyforthePromotionofAerialNavigation，assistedbytheArmyBalloonCorps，werebusyin1888，whenaseriesofimportantascentswerecommenced。UnderthedirectionofDr。Assmann，theenergeticpresidentoftheaeronauticalsocietyabovenamed，captiveascentswerearrangedinconnectionwithfreeascentsformeteorologicalpurposes，anditwasthuspracticabletomakesimultaneousobservationsatdifferentlevels。Theseexperiments，whichwerelargelytakenupontheContinent，ledtoothersofyethigherimportance，inwhichtheunmannedballoontookapart。ButtheContinentalannalsofthisdatecontainoneunhappyrecordofanothernature，therecountingofwhichwill，atleast，breakthemonotonyattendingmereexperimentaldetails。
