On the 16th it blew a strong gale from the northward, accompanied by such a constant snowdrift, that, although the weather was quite clear overhead, the boathouse at the distance of three or four hundred yards could scarcely be seen from the ships. On such occasions no person was permitted on any account to leave the ships. Indeed, when this snowdrift occurred, as it frequently did in the winter, with a hard gale and the thermometer very low, I believe that no human being could have remained alive after an hour's exposure to it. In order, therefore, to secure a communication between the two ships, a distance not exceeding half a cable's length, as well as from the ships to the house on shore, a line was kept extended, as a guide from one to the other. The meridian, altitude of the sun was observed this day by an artificial horizon, which I noticed from the circumstance of its being the last time we had an opportunity of observing it for about four months.
On the 26th the sun afforded us sufficient light or writing and reading in my cabin, the stern-windows exactly facing the south, from half past nine till half past two; for the rest of the four-and-twenty hours, we lived, of course, by candle-light. Nothing could exceed the beauty of the sky to the southeast and southwest at sunrise and sunset about this period: near the horizon there was generally a rich bluish purple and a bright arch of deep red above, the one mingling imperceptibly with the other.
It now became rather a painful experiment to touch any metallic substance in the open air with the naked hand; the feeling produced by it exactly resembling that occasioned by the opposite extreme of intense heat, and taking off the skin from the part affected. We found it necessary, therefore, to use great caution in handling our sextants and other instruments, particularly the eye-pieces of telescopes, which, if suffered to touch the face, occasioned an intense burning pain; but this was easily remedied by covering them over with soft leather. Another effect, with regard to the use of instruments, began to appear about this time. Whenever any instrument which had been some time exposed to the atmosphere, so as to be cooled down to the same temperature, was suddenly brought below into the cabins, the vapour was instantly condensed all around it, so as to give the instrument the appearance of smoking, and the glasses were covered almost instantly with a thin coating of ice, the removal of which required great caution, to prevent the risk of injuring them, until it had gradually thawed, as they acquired the temperature of the cabin. When a candle was placed in a certain direction from the instrument with respect to the observer, a number of very minute spiculæ of snow were also seen sparkling around the instrument, at the distance of two or three inches from it, occasioned, as we supposed, by the cold atmosphere produced by the low temperature of the instrument almost instantaneously congealing into that form the vapour which floated in its immediate neighbourhood.
The 4th of November being the last day that the sun would, independently of the effects of refraction, be seen above our horizon till the 8th of February, an interval of ninety-six days, it was a matter of considerable regret to us that the weather about this time was not sufficiently clear to allow us to see and make observations on the disappearance of that luminary, in order that something might be attempted towards determining the amount of the atmospheric refraction at a low temperature. But though we were not permitted to take a last farewell, for at least three months, of that cheering orb, "of this great world both eye and soul," we nevertheless felt that this day constituted an important and memorable epoch in our voyage. We had some time before set about the preparations for our winter's amusements; and the theatre being ready, we opened on the 5th November, with the representation of Miss in her Teens, which afforded to the men such a fund of amusement as fully to justify the expectations we had formed of the utility of theatrical entertainments under our present circumstances, and to determine me to follow them up at stated periods. I found, indeed, that even the occupation of fitting up the theatre and taking it to pieces again, which employed a number of the men for a day or two before and after each performance, was a matter of no little importance, when the immediate duties of the ship appeared by no means sufficient for that purpose; for I dreaded the want of employment as one of the worst evils that was likely to befall us.
About the time of the sun's leaving us, the wolves began to approach the ships more boldly, howling most piteously on the beach near us, sometimes for hours together, and on one or two occasions coming alongside the ships, when everything was quiet at night; but we seldom saw more than one or two together, and therefore could form no idea of their number. These animals were always very shy of coming near our people; and though evidently suffering much from hunger, never attempted to attack any of them. The white foxes used also to visit the ships at night, and one of these was caught in a trap set under the Griper's bows. The uneasiness displayed by this beautiful little animal during the time of his confinement, whenever he heard the howling of a wolf near the ships, impressed us with the opinion that the latter is in the habit of hunting the fox as his prey.
The temperature of the atmosphere having about this time become considerably lower than before, the cracking of the timbers was very frequent and loud for a time; but generally ceased altogether in an hour or two after this fall had taken place in the thermometer, and did not occur again at the same temperature during the winter. The wind blowing fresh from the northward, with a heavy snowdrift, made the ship very cold below; so that the breath and other vapour accumulated during the night in the bed places and upon the beams, and then immediately froze; hence it often occupied all hands for two or three hours during the day to scrape the ice away, in order to prevent the bedding from becoming wet by the increase of temperature occasioned by the fires. It was therefore found necessary to keep some of the fires in between decks at night, when the thermometer was below -15° or -20° in the open air, especially when the wind was high. To assist in keeping the lower decks warm, as well as to retard, in some slight degree, the formation of ice immediately in contact with the ships' bends, we banked the snow up against their sides as high as the main chains; and canvass screens were nailed round all the hatchways on the lower deck.
The stars of the second magnitude in Ursa Major were just perceptible to the naked eye a little after noon this day, and the Aurora Borealis appeared faintly in the southwest at night. About this time our medical gentlemen began to remark the extreme difficulty with which sores of every kind healed; a circumstance that rendered it the more necessary to be cautious in exposing the men to frostbites, lest the long inactivity and want of exercise during the cure of sores, in other respects trifling, should produce serious effects upon the general health of the patients.
During the following fortnight we were chiefly occupied in observing various phenomena in the heavens, the vivid coruscations of the Aurora Borealis, the falling of meteors, and in taking lunar distances; but the difficulty of making observations in this climate is inconceivably great; on one occasion the mercury of the artificial horizon froze into a solid mass.
About this part of the winter we began to experience a more serious inconvenience from the bursting of the lemon-juice bottles by frost, the whole contents being frequently frozen into a solid mass, except a small portion of highly concentrated acid in the centre, which in most instances was found to have leaked out, so that when the ice was thawed it was little better than water. This evil increased to a very alarming degree in the course of the winter: some cases being opened in which more than two thirds of the lemon-juice was thus destroyed, and the remainder rendered nearly inefficient.
It was at first supposed that this accident might have been prevented by not quite filling the bottles, but it was afterward found that the corks flying out did not save them from breaking. We observed that the greatest damage was done in those cases which were stowed nearest to the ship's side, and we therefore removed all the rest amidships; a precaution which, had it been sooner known and adopted, would probably have prevented at least a part of the mischief. The vinegar also became frozen in the casks in the same manner, and lost a great deal of its acidity when thawed. This circumstance conferred an additional value on a few gallons of very highly concentrated vinegar, which had been sent out on trial upon this and the preceding voyage, and which, when mixed with six or seven times its own quantity of water, was sufficiently acid for every purpose. This vinegar, when exposed to the temperature of 25° below zero, congealed only into a consistence like that of the thickest honey, but was never sufficiently hard to break any vessel which contained it. There can be no doubt, therefore, that on this account, as well as to save stowage, this kind of vinegar should exclusively be used in these regions; and for similar reasons of still greater importance, the lemon-juice should be concentrated.
