•■ a - •. - -LONDON, September 18.. ■•.'-A- message- received by.Reuter states .that the balloon in which Dr Andree left for the North Pole was sighted -at Yeniseisk, in :SibeHa/on September 14.
Ina letter to a Swedish new3pap|r, Dp*:, Nil. Ekholm, who accompanied Herr Andida toSpitzbergeh last year with-the fntehtionr of taking part in his aerial offers :Bome remarks on the of the expedition'based on the full - - Herr AndieVs accent on June 11.;- Herr Ekholm declined to go this year- because that the impermeability, of the. balloon was unsatisfactory. lii his letter he points out that from the day ..the** balloon -wasfjully inflated it lost fifty-one cubic metres of-gas every twenty-four hours, representing diminution in;barrying capacity.of fifty-six kilograms per dayv This, he says, shows that the imperviottsness of the balloon had not been essentially increased since.last year. Besides "this daily; ; escape, various circumstances led tol a; certain loss of gas in the ascent .itself, necessitating a corresponding sacrifice of ballast. ; After making allowance for these Ibsses of gas, and taking into consideration the fact that in the ascent part of^the tfereTostyana that the balloon at once rose.to a height 6f 15,000 ft to 25,0OQft—which was more i. had been reckoned upon-rDr Ekholm conies to tbe following conclusions-.—Thei longest time for which the" balloon would", remain in the air would be from-tVenty-two to twehty-four days, and leas if mountains exceeding the height attained at the start had to be crossed. As the duration of the" projected vovage niaj-be estimated in ordinary conditions as regards wind at twenty-four days, remarkable good fortune would be necessary for success. ?
