Thus passed the whole of December, rain and intermittent falls of snow succeeded each other, the temperature meanwhile varying from 26° to 34° Fahrenheit. The consumption of fuel was moderate, although there was no need to economise it, the reserves being considerable. It was otherwise with the oil, upon which they depended for light, for the stock was getting so low that the Lieutenant could at last only allow the lamps to be lit for a few hours every day. He tried using reindeer fat for lighting the house, but the smell of it was so unbearable that every one preferred being in the dark. All work had of course to be given up for the time, and very tedious did the long dark hours appear. Some Auroræ Borealis and two or three lunar halos appeared at full moon, and Thomas Black might now have minutely observed all these phenomenon, and have made precise calculations on their intensity, their coloration, connection with the electric state of the atmosphere, and their influence upon the magnetic needle, &c. But the astronomer did not even leave his room. His spirit was completely crushed. On the 30th December the light of the moon revealed a long circular line of icebergs shutting in the horizon on the north and east of Victoria Island. This was the ice-wall, the frozen masses of which were piled up to a height of some three or four hundred feet. Two-thirds of the island were hemmed in by this mighty barrier, and it seemed probable that the blockade would become yet more complete. The sky was clear for the first week of January. The new year, 1861, opened with very cold weather, and the column of mercury fell to 8° Fahrenheit. It was the lowest temperature that had yet been experienced in this singular winter, although it was anything but low for such a high latitude. The Lieutenant felt it his duty once more to take the latitude and longitude of the island by means of stellar observations, and found that its position had not changed at all. About this time, in spite of all their economy, the oil seemed likely to fail altogether. The sun would not appear above the horizon before early in February, so that there was a month to wait, during which there was a danger of the colonists having to remain in complete darkness. Thanks to the young Esquimaux, however, a fresh supply of oil for the lamps was obtained. On the 3rd January Kalumah walked to Cape Bathurst to examine the state of the ice. All along the south of the island the ice-field was very compact, the icicles of which it was composed were more firmly welded together, there were no liquid spaces between them, and the surface of the floe, though rough, was perfectly firm everywhere. This was no doubt caused by the pressure of the chain of icebergs on the horizon, which drove the ice towards the north, and squeezed it against the island.
