October.—Our present winter arrangements so closely resembled, in general, those before adopted, that a fresh description of them here would prove little more than a repetition of that already contained in the narratives of our former voyages. On each succeeding occasion, however, some improvements were made which, for the benefit of those hereafter engaged in similar enterprises, it may be proper to record. For all those whose lot it may be to succeed us, sooner or later, in these inhospitable regions, may be assured that it is only by rigid and unremitted attention to these and numberless other “little things” that they can hope to enjoy the good state of health which, under the Divine blessing, it has always been our happiness, in so extraordinary a degree, to experience.
In the description I shall offer of the appearances of nature, and of the various occurrences, during this winter, I know not how I can do better than pursue a method similar to that heretofore practised, by confining myself rather to the pointing out of any difference observed in them now and formerly, than by entering on a fresh description of the actual phenomena. To those who read, as well as to those who describe, the account of a winter passed in these regions can no longer be expected to afford the interest of novelty it once possessed; more especially in a station already delineated with tolerable geographical precision on our maps, and thus, as it were, brought near to our firesides at home. Independently, indeed, of this circumstance, it is hard to conceive any one thing more like another than two winters passed in the higher latitudes of the Polar regions, except when variety happens to be afforded by intercourse with some other branch of “the whole family of man.” Winter after winter, nature here assumes an aspect so much alike, that cursory observation can scarcely detect a single feature of variety. The winter of more temperate climates, and even in some of no slight severity, is occasionally diversified by a thaw, which at once gives variety and comparative cheerfulness to the prospect. But here, when once the earth is covered, all is dreary, monotonous whiteness—not merely for days or weeks, but for more than half a year together. Whichever way the eye is turned, it meets a picture calculated to impress upon the mind an idea of inanimate stillness, of that motionless torpor with which our feelings have nothing congenial; of anything, in short, but life. In the very silence there is a deadness with which a human spectator appears out of keeping. The presence of man seems an intrusion on the dreary solitude of this wintry desert, which even its native animals have for awhile forsaken.
As this general description of the aspect of nature would suit alike each winter we have passed in the ice, so also, with very little variation, might our limited catalogue of occurrences and adventures serve equally for any one of those seasons. Creatures of circumstance, we act and feel as we did before on every like occasion, and as others will probably do after us in the same situation. Whatever difference time or events may have wrought in individual feelings, and however different the occupations which those feelings may have suggested, they are not such as, without impertinence, can be intruded upon others; with these “the stranger intermeddleth not.” I am persuaded, therefore, that I shall be excused in sparing the dulness of another winter’s diary, and confining myself exclusively to those facts which appear to possess any scientific interest, to the few incidents which did diversify our confinement, and to such remarks as may contribute to the health and comfort of any future sojourners in these dreary regions.
It may well be supposed that, in this climate, the principal desideratum which art is called upon to furnish for the promotion of health, is warmth, as well in the external air as in the inhabited apartments. Exposure to a cold atmosphere, when the body is well clothed, produces no bad effect whatever beyond a frost-bitten cheek, nose, or finger. As for any injury to healthy lungs from the breathing of cold air, or from sudden changes from this into a warm atmosphere, or vice versâ, it may with much confidence be asserted that, with due attention to external clothing, there is nothing in this respect to be apprehended. This inference, at least, would appear legitimate, from the fact that our crews, consisting of one hundred and twenty persons, have for four winters been constantly undergoing, for months together, a change of from eighty to a hundred degrees of temperature, in the space of time required for opening two doors (perhaps less than half a minute), without incurring any pulmonary complaints at all. Nor is a covering for the mouth at all necessary under these circumstances, though to most persons very conducive to comfort; for some individuals, from extreme dislike to the condensation and freezing of the breath about the “comforter” generally used for this purpose, have never worn any such defence for the mouth; and this without the slightest injurious effect or uncomfortable feeling beyond that of a cold face, which becomes comparatively trifling by habit.
In speaking of the external clothing sufficient for health in this climate, it must be confessed that, in severe exposure, quite a load of woollen clothes, even of the best quality, is insufficient to retain a comfortable degree of warmth; a strong breeze carrying it off so rapidly that the sensation is that of the cold piercing through the body. A jacket made very long, like those called by seamen “pea-jackets,” and lined with fur throughout, would be more effectual than twice the weight of woollen clothes, and is indeed almost weather-proof. For the prevention of lumbago, to which our seamen are especially liable, from their well-known habit of leaving their loins imperfectly clothed, every man should be strictly obliged to wear, under his outer clothes, a canvas belt a foot broad, lined with flannel, and having straps to go over the shoulder.
It is certain, however, that no precautions in clothing are sufficient to maintain health during a Polar winter, without a due degree of warmth in the apartments we inhabit. Most persons are apt to associate with the idea of warmth, something like the comfort derived from a good fire on a winter’s evening at home; but in these regions the case is inconceivably different: here it is not simple comfort, but health, and therefore ultimately life, that depends upon it. The want of a constant supply of warmth is here immediately followed by a condensation of all the moisture, whether from the breath, victuals, or other sources, into abundant drops of water, very rapidly forming on all the coldest parts of the deck. A still lower temperature modifies, and perhaps improves the annoyance by converting it into ice, which again an occasional increase of warmth dissolves into water. Nor is this the amount of the evil, though it is the only visible part of it; for not only is a moist atmosphere thus incessantly kept up, but it is rendered stagnant also by the want of that ventilation which warmth alone can furnish. With an apartment in this state, the men’s clothes and bedding are continually in a moist and unwholesome condition, generating a deleterious air, which there is no circulation to carry off; and whenever these circumstances combine for any length of time together, so surely may the scurvy, to say nothing of other diseases, be confidently expected to exhibit itself.
With a strong conviction of these facts, arising from the extreme anxiety with which I have been accustomed to watch every minute circumstance connected with the health of our people, it may be conceived how highly I must appreciate any means that can be devised to counteract effects so pernicious. Such means have been completely furnished by Mr. Sylvester’s warming apparatus—a contrivance of which I scarcely know how to express my admiration in adequate terms. The alteration adopted on this voyage, of placing this stove in the very bottom of the hold, produced not only the effect naturally to be expected from it, of increasing the rapidity of the current of warm air, and thus carrying it to all the officers’ cabins with less loss of heat in its passage; but was also accompanied by an advantage scarcely less important, which had not been anticipated. This was the perfect and uniform warmth maintained during the winter in both cable-tiers, which, when cleared of all the stores, gave us another habitable deck, on which more than one-third of the men’s hammocks were berthed, thus affording to the ships’ companies, during seven or eight months of the year, the indescribable comfort of nearly twice the space for their beds, and twice the volume of air to breathe in. It need scarcely be added, how conducive to wholesome ventilation, and to the prevention of moisture below, such an arrangement proved; suffice it to say, that we have never before been so free from moisture, and that I cannot but chiefly attribute to this apparatus the unprecedented good state of health we enjoyed during this winter.
Every attention was, as usual, paid to the occupation and diversion of the men’s minds, as well as to the regularity of their bodily exercise. Our former amusements being almost worn threadbare, it required some ingenuity to devise any plan that should possess the charm of novelty to recommend it. This purpose was completely answered, however, by a proposal of Captain Hoppner, to attempt a masquerade, in which officers and men should alike take part, but which, without imposing any restraint whatever, would leave every one to their own choice, whether to join in this diversion or not. It is impossible that any idea could have proved more happy or more exactly suited to our situation. Admirably dressed characters of various descriptions readily took their parts, and many of these were supported with a degree of spirit and genuine humour which would not have disgraced a more refined assembly; while the latter might not have disdained, and would not have been disgraced by copying the good order, decorum, and inoffensive cheerfulness which our humble masquerades presented. It does especial credit to the dispositions and good sense of our men that, though all the officers entered fully into the spirit of these amusements, which took place once a month alternately on board each ship, no instance occurred of anything that could interfere with the regular discipline, or at all weaken the respect of the men towards their superiors. Ours were masquerades without licentiousness—carnivals without excess.
But an occupation not less assiduously pursued, and of infinitely more eventual benefit, was furnished by the re-establishment of our schools, under the voluntary superintendence of my friend Mr. Hooper in the Hecla, and of Mr. Mogg in the Fury. By the judicious zeal of Mr. Hooper, the Hecla’s school was made subservient, not merely to the improvement of the men in reading and writing (in which, however, their progress was surprisingly great), but also to the cultivation of that religious feeling which so essentially improves the character of a seaman, by furnishing the highest motives for increased attention to every other duty. Nor was the benefit confined to the eighteen or twenty individuals whose want of scholarship brought them to the school-table, but extended itself to the rest of the ship’s company, making the whole lower-deck such a scene of quiet, rational occupation as I never before witnessed on board a ship. And I do not speak lightly, when I express my thorough persuasion that to the moral effects thus produced upon the minds of the men were owing, in a very high degree, the constant yet sober cheerfulness, the uninterrupted good order, and even, in some measure, the extraordinary state of health which prevailed among us during this winter.
Immediately after the ships were finally secured, we erected the observatory on shore, and commenced our arrangements for the various observations to which our attention was to be directed during the winter. The interest of these, especially of such as related to magnetism, increased so much as we proceeded, that the neighbourhood of the observatory assumed ere long almost the appearance of a scattered village, the number of detached houses, having various needles set up in them, soon amounting to seven or eight.
The extreme facility with which sounds are heard at a considerable distance in severely cold weather has often been a subject of remark; but a circumstance occurred at Port Bowen which deserves to be noticed, as affording a sort of measure of this facility, or at least conveying to others some definite idea of the fact. Lieutenant Foster, having occasion to send a man from the observatory to the opposite shore of the harbour, a measured distance of 6696 feet, or about one statute mile and two-tenths, in order to fix a meridian mark, had placed a second person half-way between to repeat his directions; but he found, on trial, that this precaution was unnecessary, as he could without difficulty keep up a conversation with the man at the distant station. The thermometer was at this time −18°, the barometer 30.14 inches, and the weather nearly calm, and quite clear and serene.
The meteorological phenomena observed during this winter, like most of its other occurrences, differed so little in character from those noticed on the former voyages, as to render a separate description of each wholly unnecessary.
This winter certainly afforded but few brilliant displays of the Aurora. The following notice includes all that appear to me to require a separate description.
Late on the night of the 21st of December the phenomenon appeared partially, and with a variable light, in different parts of the southern sky for several hours. At seven on the following morning it became more brilliant and stationary, describing a well-defined arch, extending from the E.S.E. horizon to that at W.N.W., and passing through the zenith. A very faint arch was also visible on each side of this, appearing to diverge from the same points in the horizon, and separating to twenty degrees distance in the zenith. It remained thus for twenty minutes, when the coruscations from each arch met, and after a short but brilliant display of light, gradually died away. Early on the morning of the 15th of January, 1825, the Aurora broke out to the southward, and continued variable for three hours, between a N.W. and S.E. bearing. From three to four o’clock the whole horizon, from south to west, was brilliantly illuminated, the light being continuous almost throughout the whole extent, and reaching several degrees in height. Very bright vertical rays were constantly shooting upwards from the general mass. At half-past five it again became so brilliant as to attract particular notice, describing two arches passing in an east and west direction, very near the zenith, with bright coruscations issuing from it; but the whole gradually disappeared with the returning dawn. At dusk the same evening, the Aurora again appeared in the southern quarter, and continued visible nearly the whole night, but without any remarkable feature.
About midnight on the 27th of January, this phenomenon broke out in a single compact mass of brilliant yellow light, situated about a S.E. bearing, and appearing only a short distance above the land. This mass of light, notwithstanding its general continuity, sometimes appeared to be evidently composed of numerous pencils of rays, compressed, as it were, laterally into one, its limits both to the right and left being well defined and nearly vertical. The light, though very bright at all times, varied almost constantly in intensity, and this had the appearance (not an uncommon one in the Aurora) of being produced by one volume of light overlaying another, just as we see the darkness and density of smoke increased by cloud rolling over cloud. While Lieutenants Sherer and Ross, and myself, were admiring the extreme beauty of this phenomenon from the observatory, we all simultaneously uttered an exclamation of surprise at seeing a bright ray of the Aurora shoot suddenly downward from the general mass of light, and between us and the land, which was there distant only three thousand yards. Had I witnessed this phenomenon by myself, I should have been disposed to receive with caution the evidence even of my own senses, as to this last fact; but the appearance conveying precisely the same idea to three individuals at once, all intently engaged in looking towards the spot, I have no doubt that the ray of light actually passed within that distance of us.
About one o’clock on the morning of the 23rd of February, the Aurora again appeared over the hills in a south direction, presenting a brilliant mass of light, very similar to that just described. The rolling motion of the light laterally was here also very striking, as well as the increase of its intensity thus occasioned. The light occupied horizontally about a point of the compass, and extended in height scarcely a degree above the land, which seemed, however, to conceal from us a part of the phenomenon. It was always evident enough that the most attenuated light of the Aurora sensibly dimmed the stars, like a thin veil drawn over them. We frequently listened for any sound proceeding from this phenomenon, but never heard any. Our variation-needles, which were extremely light, suspended in the most delicate manner, and from the weak directive energy susceptible of being acted upon by a very slight disturbing force, were never in a single instance sensibly affected by the Aurora, which could scarcely fail to have been observed at some time or other, had any such disturbance taken place, the needles being visited every hour for several months, and oftener, when anything occurred to make it desirable.
The meteors called Falling-stars were much more frequent during this winter than we ever before saw them, and particularly during the month of December. On the 8th, at a quarter past seven in the evening, a particularly large and brilliant meteor of this kind fell in the S.S.W., the weather being very fine and clear overhead, but hazy near the horizon. On the following day, between four and five P.M., another very brilliant one was observed in the north, falling from an altitude of about thirty-five degrees till lost behind the land; the weather was at this time clear and serene, and no remarkable change took place. On the 12th, no less than five meteors of this kind were observed in a quarter of an hour, and as these were attended with some remarkable circumstances, I shall here give the account furnished me by Mr. Ross, who with Mr. Bell observed these phenomena. “From seven to nine P.M. the wind suddenly increased from a moderate breeze to a strong gale from the southward. At ten it began to moderate a little; the haze, which had for several hours obscured every star, gradually sinking towards the horizon, and by eleven o’clock the whole atmosphere was extremely clear above the altitude of five or six degrees. The thermometer also fell from −5° to −9° as the haze cleared away. At a quarter past eleven my attention was directed by Mr. Bell to some meteors which he observed, and in less than a quarter of an hour five were seen. The two first, noticed only by Mr. Bell, fell in quick succession, probably not more than two minutes apart. The third appeared about eight minutes after these, and exceeded in brilliancy any of the surrounding stars. It took a direction from near β Tauri, and passing slowly towards the Pleiades, left behind it sparks like the tail of a rocket, these being visible for a few seconds after the meteor appeared to break, which it did close to the Pleiades. The fourth meteor made its appearance very near the same place as the last, and about five minutes after it. Taking the course of those seen by Mr. Bell, it passed to the eastward, and disappeared half way between β Tauri and Gemini. The fifth of these meteors was seen to the eastward, passing through a space of about five degrees from north to south parallel to the horizon, and moving along the upper part of the cloud of haze which still extended to the altitude of five or six degrees. It was more dim than the rest, and of a red colour like Aldebaran. The third of these meteors was the only one that left a tail behind it, as above described. There was a faint appearance of the Aurora to the westward near the horizon.
On the 14th of December several very bright meteors were observed to fall between the hours of five and six in the evening, at which time the wind freshened from the N.W. by N. in a very remarkable manner. On this occasion, as well as on the 12th of December, there appeared to be an evident coincidence between the occurrence of the meteors and the changes of the weather at the time.
Particular attention was paid to the changes in the barometer during this winter, to which much encouragement was given by the excellence of the instruments with which we were now furnished. The times of register at sea had been three and nine, A.M. and P.M.; those hours having been recommended as the most proper for detecting any horary oscillations of the mercurial column. When we were fixed for the winter, and our attention could be more exclusively devoted to scientific objects, the register was extended to four and ten, and subsequently to five and eleven o’clock. The most rigid attention to the observation and correction of the column, during several months, discovered an oscillation amounting only to ten thousandth-parts of an inch. The times of the maximum and minimum altitude appear, however, decidedly to lean to four and ten o’clock, and to follow a law directly the reverse, as to time, of that found to obtain in temperate climates, the column being highest at four, and lowest at ten o’clock, both A.M. and P.M.
The barometer did not appear to indicate beforehand the changes of the weather with any degree of certainty. Indeed the remark that we had always before made, that alterations in the mercurial column more frequently accompany than precede the visible changes of weather in these regions, was equally true of our present experience; but on one or two occasions hard gales of considerable duration occurred without the barometer falling at all below the mean altitude of the column in these regions, or even rose steadily during the continuance of the gale. During one week of almost constant blowing weather, and two days of very violent gales from the eastward, in the month of April, the barometer remained considerably above thirty inches the whole time. It is necessary for me here to remark that the unusual proportion of easterly winds registered in our journals during this winter must, in my opinion, be attributed to the local situation of our winter-quarters, which alone appears to me sufficient to account for the anomaly. The lands on each side of Port Bowen, running nearly east and west, and rising to a height of six to nine hundred feet above the sea, with deep and broad ravines intersecting the country in almost every direction, may be supposed to have had considerable influence on the direction of the wind. In confirmation of this supposition, indeed, it was usually noticed that the easterly winds were with us attended with clear weather, while the contrary obtained with almost every breeze from the west and north-west, thus reversing in this respect also the usual order of things. It was moreover observed that the clouds were frequently coming from the north-west, when the wind in Port Bowen was easterly. I must, however, except the gales we experienced from the eastward, which were probably strong enough to overcome any local deflection to which a light breeze would be subject; and indeed these were always accompanied with overcast weather and a high thermometer. After the middle of October the gales of wind were very few till towards the middle of April, when we experienced more blowing weather than during the whole winter.
