Read it through once

In the morning, however, as soon as it was light, I went upon deck and found all the sailors busy on one side of the vessel, apparently talking to someone in the sea. It was, in fact, a sledge, like that we had seen before, which had drifted towards us in the night on a large fragment of ice. Only one dog remained alive; but there was a human being within it whom the sailors were persuading to enter the vessel. He was not, as the other traveller seemed to be, a savage inhabitant of some undiscovered island, but a European. When I appeared on deck the master said, “Here is our captain, and he will not allow you to perish on the open sea.”
