 CHAPTER XXIL FIVE MONTHS MORE. VIOLENT earthquake had shaken Cape Bathurst. Such convulsions were probably frequent in this volcanic region, and the connection between them and eruptions was once more demonstrated. Hobson well understood the significance of what had occurred, and waited in anxious suspense. He knew that the earth might open and swallow up the little colony ; but only one shock was felt, and that was rather a rebound than a vertical upheaval, which made the house lean over towards the lake, and burst open its walls. Immediately after this one shock, the ground again became firm and motionless. The house, although damaged, was still habitable ; the breaches in the walls were quickly repaired, and the pipes of the chimneys were patched together again somehow. Fortunately the wounds the soldiers had received in their struggle with the bears were slight, and merely required dressing. Two miserable days ensued, during which the woodwork of the beds and the planks of the partition walls were burnt, and the most pressing repairs executed by Mac-Nab and his men. The piles, well driven into the earth, had not yielded ; but it was evident that the earthquake had caused a sinking of the level of the coast on which the fort was built, which might seriously compromise the safety of the building. Hobson was most anxious to ascertain the extent of the alteration of elevation, but the pitiless cold prevented him from venturing outside. But at last there were symptoms of an approaching change in the weather. The stars shone with rather less brilliancy, and on the 11th January the barometer fell slightly; hazy vapours floated in the air, the condensation of which would raise the temperature ; and on the 12th January the wind veered to the south-west, and snow fell at irregular intervals.
