Mr。Spencer’sopinion,carefullyconsideredandexpressedeighteenmonthsafterwards,willbereadwithrealinterest:——
"ThedistancefromDane’sIslandtothePoleisabout750

ArecordofthedirectionofthewindwasmadeafterAndree’sdeparture,andprovedthattherewasafluctuationindirectionfromS。W。toN。W。,indicatingthatthevoyagersmayhavebeenborneacrosstowardsSiberia。This,however,canbebutsurmise。Allaeronautsofexperienceknowthatitisanexceedinglydifficultmanoeuvretokeepatrailropedraggingonthegroundifitisdesirabletopreventcontactwiththeearthontheonehand,orontheothertoavoidlossofgas。A

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

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