At about a hundred paces off, burning torches were moving about, whilst reports of guns and shouts were heard.

The explorers replied, and were soon joined by Sergeant Long and others, amongst them Thomas Black, whose anxiety as to the fate of his friends had at last roused him from his torpor. The poor fellows left on the island had been in a terrible state of uneasiness, thinking that Hobson and his party had lost their way. They were right, but what was it that had made them think so?

Twenty-four hours before, the immense ice-field and the island had turned half round, and in consequence of this displacement they were no longer on the west, but on the east of the ice-wall!

CHAPTER XVI

THE BREAK-UP OF THE ICE

Two hours later all had returned to Fort Hope, and the next day the sun for the first time shone upon that part of the coast which was formerly on the west of the island. Kalumah, to whom this phenomenon was familiar, had been right, and if the sun had not been the guilty party neither had the compass!

The position of Victoria Island with regard to the cardinal points was again completely changed. Since it had broken loose from the mainland the island-and not only the island, but the vast ice field in which it was enclosed-had turned half round. This displacement proved that the ice-field was not connected with the continent, and that the thaw would soon set in.

"Well, Lieutenant," said Mrs. Barnett, "this change of front is certainly in our favour. Cape Bathurst and Fort Hope are now turned towards the north-east, in other words towards the point nearest to the continent, and the ice-wall, through which our boat could only have made its way by a difficult and dangerous passage, is no longer between us and America. And so all is for the best, is it not?" added Mrs. Barnett with a smile.

"Indeed it is," replied Hobson, who fully realised all that was involved in this change of the position of Victoria Island.
