On the 20th April Lieutenant Hobson ascertained that the wandering island was still drifting to the south. All that remained of the ice-wall, that is to say, the southern portion of the icebergs, followed it, but as there were no bench marks, the changes of position could only be estimated by astronomical observations. Hobson took several soundings in different parts of the ground, especially at the foot of Cape Bathurst, and on the shores of the lagoon. He was anxious to ascertain the thickness of the layer of ice supporting the earth and sand, and found that it had not increased during the winter, and that the general level of the island did not appear to have risen higher above that of the sea. The conclusion he drew from these facts was, that no time should be lost in getting away from the fragile island, which would rapidly break up and dissolve in the warmer waters of the Pacific. About the 25th April the bearing of the island was again changed, the whole ice-field had moved round from east to west twelve points, so that Cape Bathurst pointed to the north-west. The last remains of the ice-wall now shut in the northern horizon, so that there could be no doubt that the ice-field was moving freely in the strait, and that it nowhere touched any land. The fatal moment was approaching. Diurnal or nocturnal observations gave the exact position of the island, and consequently of the ice-field. On the 30th of April, both were together drifting across Kotzebue Sound, a large triangular gulf running some distance inland on the American coast, and bounded on the south by Cape Prince of Wales, which might, perhaps, arrest the course of the island if it should deviate in the very least from the middle of the narrow pass. The weather was now pretty fine, and the column of mercury often marked 50° Fahrenheit. The colonists had left off their winter garments some weeks before, and held themselves in constant readiness to leave the island. Thomas Black had already transported his instruments and books into the boat, which was waiting on the beach. A good many provisions had also been embarked and some of the most valuable furs. On the 2d of May a very carefully taken observation showed that Victoria Island had a tendency to drift towards the east, and consequently to reach the American continent. This was fortunate, as they were now out of danger of being taken any farther by the Kamtchatka Current, which, as is well known, runs along the coast of Asia. At last the tide was turning in favour of the colonists! “I think our bad fortune is at last at an end,” observed Sergeant Long to Mrs Barnett, “and that our misfortunes are really over; I don’t suppose there are any more dangers to be feared now.” “I quite agree with you,” replied Mrs Barnett, “and it is very fortunate that we had to give up our journey across the ice-field a few months ago; we ought to be very thankful that it was impassible!”
