But,erethis,anumberofsomewhatsimilarexperiments,onbehalfoftheFrenchGovernment,hadbeenentereduponbyCaptainsRenardandKrebsatChalais—Meudon。Theirballoonmaybedescribedasfish—shaped,165feetlong,and27。5feetinprincipaldiameter。Itwasoperatedbyanelectricmotor,whichwascapableofdrivingascrewoflargedimensionsatforty—eightrevolutionsperminute。Atitsfirsttrial,inAugust,1884,indeadcalm,itattainedavelocityofovertwelvemilesperhour,travellingsometwoandahalfmilesinaforwarddirection,when,byapplicationoftherudderandjudiciousmanagement,itwasmanoeuvredhomewards,andpracticallybroughttoearthatthepointofdeparture。

Aboutthisperiod,thatisin1883,andreallypriortotheMeudonexperiments,therewereotherattemptsataeriallocomotionnottobealtogetherpassedover,whichweremadealsoinFrance,butfinancedbyEnglishmoney。TheexperimentswereperformedbyMr。F。A。Gower,who,writingtoProfessorTyndall,claimstohavesucceededin"drivingalargeballoonfairlyagainstthewindbysteampower。"AmelancholyinterestwillalwaysbelongtothesetrialsfromthefactthatMr。Gowerwassubsequentlyblownouttoseawithhisballoon,leavingnotracebehind。

ButCaptainBurnabyisassociatednotablywiththeadventuroussideofballooning,themostfamousofhisaerialexploitsbeing,perhaps,thatofcrossingtheEnglishChannelalonefromDoveronMarch23rd,1882。Outwardly,hemadepresenceofsailingtoParisbyskytodinetherethatevening;inwardly,hehaddeterminedtostartsimplywithawindwhichbidfairforacross—Channeltrip,andtotakewhateverchancesitmightbringhim。
