The first mate promised obedience; and the second mate having been also cautioned to hug the land, and not to use their small supply of spirits for any other purpose than that of lighting the lamp, except in cases of the most urgent need, they set off with three hearty cheers, which were returned by Captain Guy and those who remained with him in the ship. All the able and effective men were sent on these expeditions; those who remained behind were all more or less affected with scurvy, except the captain himself, whose energetic nature seemed invulnerable, and whose flow of spirits never failed. Indeed, it is probable that to this hearty and vigorous temperament, under God, he owed his immunity from disease; for, since provisions began to fail, he along with all his officers had fared precisely like the men--the few delicacies they possessed having been reserved for the sick. Unfortunately, their stock of lime-juice was now getting low, and the crew had to be put on short allowance. As this acid is an excellent anti-scorbutic, or preventive of scurvy, as well as a cure, its rapid diminution was viewed with much concern by all on board. The long-continued absence of the sun, too, now began to tell more severely than ever on men and dogs. On the very day the expeditions took their departure one of the latter, which had been left behind on account of illness, was attacked with a strange disease, of which several of the team eventually died before the winter came to an end. It was seized with spasms, and, after a few wild paroxysms, lapsed into a lethargic state. In this condition the animal functions went on apparently as well as usual, the appetite continued not only good but voracious. The disease was clearly mental. It barked furiously at nothing, and walked in straight or curved lines perseveringly; or, at other times, it remained for hours in moody silence, and then started off howling as if pursued. In thirty-six hours after the first attack the poor animal died, and was buried in the snow on Store Island. This was the first death that had occurred on board, and although it was only a dog, and not one of the favourites, its loss cast a gloom over the crew for several days. It was the first blow of the fell destroyer in the midst of their little community, which could ill spare the life even of one of the lower animals, and they felt as if the point of the wedge had now been entered, and might be driven farther home ere long.
