306 THE FUR COUNTRY, Behring Sea had already changed from blue to green, as the great navigator Hudson observed they always do on the approach of icebergs, so that a catastrophe might be expected at any moment. Hobson determined to do his best to avert the coming misfortune, and ordered a raft to be constructed which would carry the whole colony, and might be guided to the continent somehow or other. There was every chance of meeting vessels now that the whaling season had commenced, and Mac-Nab was commissioned to make a large solid raft which would float when Victoria Island was engulfed. But first of all, it was necessary to construct some shelter for the homeless inhabitants of the island. The simple plan appeared to be to dig out the old barracks, which had been built on to the prin- cipal house, and the walls of which were still standing. Every one set to work with a hearty good-will, and in a few days a shelter was provided from the inclemencies of the fickle weather. Search was also made in the ruins of the large house, and a good many articles of more or less value were saved from the sub- merged rooms — tools, arms, furniture, the air pumps, and the air vessel, &c. On the 13th May all hope of drifting on to the island of St Lawrence had to be abandoned. When the bearings were taken, it was found that they were passing at a considerable distance to the east of that island ; and, as Hobson was well aware, currents do not run against natural obstacles, but turn them, so that little hope could be entertained of thus making the land. It is true the network of islands in the Catherine Archipelago, scattered over several degrees of latitude, might stop the island if it ever got so far. But, as we have before stated, that was not probable, although it was advancing at great speed.; for this speed must decrease considerably when the ice- wall which was driving it along should be broken away or dissolved, unprotected as it was from the heat of the sun by any covering of earth or sand. Lieutenant Hobson, ^Mrs Barnett, Sergeant Long, and the head carpenter often discussed these matters, and came to the conclusion that the island could certainly never reach the Aleutian group with so many chances against it. On the 14th May, Mac-Nab and his men commenced the con- struction of a huge raft. It had to be as high as possible above the water, to prevent the waves from breaking over it, so that it was really a formidable undertaking. The blacksmith, Rae, had fortu-
