The Arctic Ocean encircles with a belt of eternal ice the desert confines of Siberia and North America-the uttermost limits of the Old and New worlds, separated by the narrow, channel, known as Behring's Straits. The last days of September have arrived. The equinox has brought with it darkness and Northern storms, and night will quickly close the short and dismal polar day. The sky of a dull and leaden blue is faintly lighted by a sun without warmth, whose white disk, scarcely seen above the horizon, pales before the dazzling, brilliancy of the snow that covers, as far as the eyes can reach, the boundless steppes.
