 CHAPTER XX. IN THE OFFING. ICTORIA Island was now floating in the widest part of Behring Sea, six hundred miles from the nearest of the Aleutian Islands, and two hundred miles from the nearest land, which was on the east. Supposing no accident happened, it would be three weeks at least before this southern boundary of Behring Sea could be reached. Could the island last so long ? Might it not burst open at any moment, subject as it was even now to the constant action of tepid water, the mean temperature of which was more than 60° Fahren- heit? Lieutenant Hobso u pressed on the construction of the raft as rapidly as possible, and the lower framework was already floating on the lagoon. Mac-Nab wished to make it as strong as possible, for it would have a considerable distance to go to reach the Aleutian Islands, unless they were fortunate enough to meet with a whaler. No important alteration had lately taken place in the general con- figuration of the island. Reconaissances were taken every day, but great caution was necessary, as a fracture of the ground might at any moment cut off the explorers from the rest of the party. The wide gulf near Cape Michael, which the winter had closed, had reopened gradually, and now ran a mile inland, as far as the dried- up bed of the little river. It was probable that it was soon to extend to the bed itself, which was of course of little thickness, having been hollowed out by the stream. Should it do so, the whole district between Cape Michael and Port Barnett, bounded on the west by the river bed, would disappear — that is to say, the colonists would lose a good many square miles of their domain. On this account Hobson warned every one not to wander far, as a rough sea would be enough to bring about the dreaded catastrophe. Soundings were, however, taken in several places with a view to ascertaining where the ice was thickest, and it was found that, near Cape Bathurst, not only was the layer of earth and sand of greater •
