"The next march was to be Bartlett's last, and he let himself out to do his best. The going was fairly good, but the weather was thick. There was a strong northerly wind blowing full in our faces, bitter and insistent, and the temperature was in the minus thirties. But this northerly wind, though hard to struggle against, was better than an easterly or westerly one, either of which would have set us adrift in open water, while, as it was, the wind was closing up every lead behind us and thus making things easier for Bartlett's supporting party on its return. True, the wind pressure was forcing to the south the ice over which we traveled, and thus losing us miles of distance; but the advantage of frozen leads was more than compensation for this loss." - Robert E. Peary in The North Pole, published in 1910
