THE POLAR NIGHT. 121 Every one was eager to get out, the confinement had lasted long enough. The door could not be opened, and all had to get through the •window, and clear away the fresh accumulation of snow ; this time, however, it was no soft mass they had to remove, but compact blocks of ice, which required pick axes to break them up. It took about half-an-hour to clear a passage, and then every one in the fort, except Mrs Mac-Nab, who was not yet up, hastened into the interior court, glad once more to be able to walk about. The cold was still intense, but the wind having gone down it was possible to endure it, although great care was necessary to escape serious consequences on leaving the heated rooms for the open air, the difference between the temperature inside and outside being some fifty-four degrees. It was eight o'clock in the morning. Myriads of brilliant con- stellations studded the sky, and at the zenith shone the Pole star.

The roof of the house alone appeared above the white mass, the surface of which had been worn smooth by the action of the wind ; of the palisade nothing was visible but the top of the stakes, and the least nimble of the wild animals they dreaded could easily have climbed over them. But what was to be done % It was no use to think of clearing away a mass of frozen snow ten feet thick, extending over so large an extent of ground. All they could attempt would be to dig away the ice inside the enceinte, so as to form a kind of moat, the counterscarp of which would protect the palisade. But alas the winter was only beginning, and a fresh tempest might at any time fill in the ditch a few hours. Whilst the Lieutenant was examining the works, which could no
