THE ARCTIC HEAVENS: ATMOSPHERIC AND METEORIC PHENOMENA.
Let the reader fancy himself--should he be reading these pages on a
warm summer’s day, the fancy will not be unpleasant!--let the reader
fancy himself on board a well-found, stoutly-built whaling-vessel,
and rapidly approaching the coast of Greenland. But the heavy mist
hangs over the legend-haunted shores, and we can but catch the sound
of the clanging surf as it rolls upon them. All around us spreads the
mist,--dense, impenetrable. What is that before us? The dead white mass
of an iceberg, slowly drifting with the current, and almost upon us
before the look-out man discovered it. But the helm has been sharply
handled; our good ship has put about; and we sail clear of the mighty
pyramid. Fully one hundred and fifty feet high, we can assure you, and
twice as broad at its base. A sudden break in the mist reveals its
radiant spire, with white cloud-wreaths circling and dancing round it
in the sunlight.
And now, as we steadily move forward, the fog is lifted up like a
curtain, and before us, like a scene in a panorama, looms the Greenland
coast in all its austere magnificence: yonder are its broad ice-filled
valleys, its snow-clad ravines, its noble mountains, its iron-bound
range of cliffs, its general aspect of solemn desolation.
Away over the westward sea fly the scattered vapours, disclosing
iceberg after iceberg, like the magical towers in some of Turner’s
pictures. We seem to have been drawn by some irresistible spell into
a world of enchantment, and all the old Norse romance comes back
upon the memory, with its picturesque associations. Yonder lies the
Valhalla of the ancient ocean-rovers; yonder the dazzling city of the
sun-god Freya, one of the most popular of the Scandinavian divinities,
as well he might be; yonder the elfin caves of Alfheim; and Glitner,
with its walls of gold and roofs of silver; and the radiant Gimele,
the home of the blessed; and there, too, towering above the clouds,
the bridge Bifrost, by which the heroes ascended from earth to heaven.
Heimdall, who can see for fully a hundred leagues, as well by night as
by day, stands sentinel upon it, prepared to sound his horn Gjallar, if
intruders should attempt to cross it!
The sea is smooth as glass; not a ripple breaks the wonderful calmness
of its surface. It is midnight, but in this strange Arctic world the
sun still hangs close upon the northern horizon; the icebergs rear
their dazzling crests around, like floating spires, and turrets, and
many-towered minsters; the dark headlands are boldly outlined against
the sky; and sea, and sky, and mountains, and icebergs are suffused
in a wildly beautiful atmosphere of crimson, gold, and purple. The
picture is like a poet’s vision; and so startlingly unreal, that it is
difficult for the unaccustomed spectator to believe it other than an
illusion.
[Illustration: THE MIDNIGHT SUN.]
We adopt the following description from the vivid language of Dr.
Hayes, who displays a keen feeling for the beauties of the Polar world.
The air was warm, he says, almost as a summer’s night at home, and
yet there were the icebergs and the bleak mountains, with which the
fancy, in our own land of green hills and waving woods, can associate
nothing but what is cold and repellent. Bright was the sky, and soft
and strangely inspiring as the skies of Italy. The bergs had wholly
lost their chilly aspect, and, glittering in the blaze of the brilliant
heavens, seemed, in the distance, like masses of burnished metal or
solid flame. Nearer at hand they were huge blocks of Parian marble,
encrusted with colossal gems of pearl and opal. One in particular
exhibited the perfection of grandeur. Its form was not unlike that of
the Coliseum, and it lay so far away that half its height was buried
beneath the line of blood-red waters. The sun, slow moving along its
path of glory, passed behind it, and the old Roman ruin seemed suddenly
to break into flame.
[Illustration: OFF THE COAST OF GREENLAND.]
Nothing, indeed, but the pencil of the artist could depict the
wonderful richness of this combined landscape and seascape. Church, in
his great picture of “The Icebergs,” has grandly exhibited a scene not
unlike that we have attempted to describe.
In the shadows of the bergs the water was a rich green, and nothing
could be more soft and tender than the gradations of colour made by the
sea shoaling on the sloping tongues of some of these floating masses.
The tint increased in intensity where the ice overhung the waters,
and a deep cavern in one of them exhibited the solid colour of the
malachite mingled with the transparency of the emerald, while, in
strange contrast, a broad belt of cobalt blue shot diagonally through
its body.
The enchantment of the scene was heightened by a thousand little
cascades which flashed into the sea from the icebergs, the water being
discharged from basins of melted snow and ice which tranquilly reposed
far up in the hollows of their topmost surface. From other bergs large
boulders were occasionally detached, and these plunged into the water
with a deafening din, while the roll and rush of the ocean resounded
like the music of a solemn dirge through their broken archways.
* * * * *
The contrasts and combinations of colour in the Polar world are,
indeed, among its particular attractions, and of their kind they cannot
be surpassed or imitated even in the gorgeous realms of the Tropics.
The pale azure gleam of the ice, the dazzling whiteness of the snow,
the vivid verdure of the sunlit plains, the deep emerald tints, crossed
with sapphire and ultramarine, of the waters, would in themselves
afford a multiplicity of rich and beautiful effects; but to these we
must add the magical influences of the coruscations of the Arctic
heavens, with the glories of the midnight sun and the wonders of the
Aurora.
[Illustration: MOONLIGHT IN THE POLAR WORLD.]
Even moonlight in the Polar world is unlike moonlight anywhere else; it
has a character all its own,--strange, weird, supernatural. Night after
night the sky will be free from cloud or shadow, and the radiant stars
shine out with a singular intensity, seeming to cut the air like keen
swords. The moonbeams are thrown back with a pale lustre by ice-floe
and glacier and snow-drift, and the only relief to the brightness is
where the dark cliffs throw a shadow over the landscape. Gloriously
beautiful look the snow-clad mountains, as the moonlight pours upon
them its serene splendour, interrupted only by the occasional passage
of a wreath of mist, which is soon transformed into sparkling silver.
The whole scene produces an impression of awe on the mind of the
thoughtful spectator, and he feels as if brought face to face with the
visible presence of another world.
The prolonged winter night is in itself well calculated to affect the
imagination of the European. He reads of it in travels and books of
astronomy; but to know what it _is_, and what it _means_, he
must submit himself to its influence,--he must “winter” in the Polar
Regions. Not to see sunrise and sunset, and the changes they bring with
them, day after day, enlivening, inspiriting, strengthening, is felt
at first as an intolerable burden. The stars shining at all hours with
equal brilliancy, and the lasting darkness which reigns for twenty
days of each winter month when the moon is below the horizon, become a
weariness and a discomfort. The traveller longs for the reappearance
of the moon; and yet before she has run her ten days’ course, he feels
fatigued by the uniform illumination.
But sometimes a relief is supplied by the phenomenon of the Aurora
Borealis. We inhabitants of the United Kingdom know something of the
rare beauty of the “northern lights,” when the heavens kindle with
a mysterious play of colours which reminds us of the strange weird
radiance that occasionally kindles in our dreams; yet these are poor
and trivial when compared with the auroral display. Let us endeavour
to realize it from the glowing description painted by one of the most
eloquent and observant of Arctic explorers.
He was groping his way among the ice-hummocks, in the deep obscurity
of the mid-winter, when suddenly a bright ray darted up from behind
the black cloud which lay low down on the horizon before him. It
lasted but an instant, and, having filled the air with a strange
illumination, it died away, leaving the darkness even greater darkness
than before. Presently an arc of coloured light sprang across the
sky, and the aurora became gradually more fixed. The space enclosed
by the arc was very dark, and was filled with the cloud. The play of
the rays which rose from its gradually brightening border was for some
time very capricious, modifying the burst of flame from what seemed a
conflagration of the heavens to the soft glow of early morn.
Gradually the light grew more and more intense, and from irregular
bursts it settled into an almost steady sheet of splendour. This sheet,
however, was far from uniform, and may best be described as “a flood of
mingling and variously-tinted streaks.”
The exhibition, at first tame and quiet, developed by degrees into
startling brilliancy. The broad dome of night seemed all ablaze. Lurid
fires, fiercer than those which reddened the heavens from burning
Troy, flashed angrily across the zenith. The stars waned before the
marvellous outburst, and seemed to recede further and further from the
Earth; “as when the chariot of the sun, driven by Phaeton, and carried
from its beaten track by the ungovernable steeds, rushed madly through
the skies, parching the world and withering the constellations. The
gentle Andromeda flies trembling from the flame; Perseus, with his
flashing sword and Gorgon shield, retreats in fear; the Pole-Star is
chased from the night; and the Great Bear, faithful sentinel of the
North, quits his guardian watch, following the feeble trail.”
The colour of the light was chiefly red, but this was not permanent,
and every hue mingled in the wonderful display.
Blue and yellow streamers shot athwart the lurid fire; and, sometimes
starting side by side from the wide expanse of the illumined arc,
they melted into each other, and flung a weird glare of green over the
landscape.
[Illustration: THE AURORA BOREALIS.]
Again this green overcame the red; blue and yellow blended with each
other in their swift flight; violet-tinted arrows flashed through a
broad glow of orange, and countless tongues of white flame, formed of
these uniting streams, rushed aloft and clasped the skies. The effect
of the many-coloured lustre upon the surrounding objects was singularly
wonderful. The weird forms of innumerable icebergs, singly and in
clusters, loomed above the sea, and around their summits hovered the
strange gleam, like the fires of Vesuvius over the villas and temples
of Pompeii. All along the white surface of the frozen sea, upon the
mountain-peaks and the lofty cliffs, the light glowed and dimmed
and glowed again, as if the air were filled with graveyard meteors,
flitting wildly above some vast illimitable city of the dead. The scene
was noiseless, yet the senses were deceived, for sounds not of earth or
sea seemed to follow the swift coruscations, and to fall upon the ear
like
“The tread
Of phantoms dread,
With banner, and spear, and flame.”
Though the details, so to speak, are not always the same, the general
character of the aurora changes very slightly, and, from a comparison
of numerous accounts, the gradation of the phenomenon would seem to be
as follows:--
The sky slowly assumes a tint of brown, on which, as on a background,
is soon developed a nebulous segment, bordered by a spacious arc of
dazzling whiteness, which seems incessantly agitated by a tremulous
motion. From this arc an incredible number of shafts and rays of light
leap upwards to the zenith. These luminous columns pass through all
the hues of the rainbow,--from softest violet and intensest sapphire
to green and purple-red. Sometimes the rays issue from the resplendent
arc mingled with darker flashes; sometimes they rise simultaneously at
different points of the horizon, and unite in one broad sea of flame
pervaded by rapid undulations. On other occasions it would seem as if
invisible hands were unfurling fiery dazzling banners, to stream, like
meteors, in the troubled air. A kind of canopy, of soft and tranquil
light, which is known as the _corona_, indicates the close of the
marvellous exhibition; and shortly after its appearance the luminous
rays begin to decrease in splendour, the richly-coloured arcs dissolve
and die out, and soon of all the gorgeous spectacle nothing remains but
a whitish cloudy haze in those parts of the firmament which, but a few
minutes before, blazed with the mysterious fires of the aurora borealis.
[Illustration: THE AURORA BOREALIS--THE CORONA.]
The arc of the aurora is only part of a broad circle of light, which is
elevated considerably above the surface of our globe, and the centre
of which is situated in the vicinity of the Pole. It is not difficult,
therefore, to account for the different aspects under which it is
presented to observers placed at different angles to the focus of the
display. A person some degrees _south_ of the ring necessarily
sees but a very small arc of it towards the north, owing to the
interposition of the earth between him and it; if he stood nearer the
north, the arc would appear larger and higher; if immediately below
it, he would see it apparently traversing the zenith; or if within
the ring, and still further north, he would see it culminating in the
south. It has been supposed that the centre of the ring corresponds
with the magnetic north pole in the island of Boothia Felix.
Generally the phenomenon lasts for several hours, and at times it
will be varied by peculiar features. Now it will seem to present the
hemispherical segment of a colossal wheel; now it will wave and droop
like a rich tapestry of many-coloured light, in a thousand prismatic
folds; and now it exhibits the array of innumerable dazzling streamers,
waving in the dark and intense sky.
The arc varies in elevation, but is seldom more than ninety miles above
the terrestrial surface. Its diameter, however, must be enormous,
for it has been known to extend southward to Italy, and has been
simultaneously visible in Sardinia, Connecticut, and at New Orleans.
According to some authorities, the phenomenon is accompanied by noises
resembling the discharge of fireworks, or the crackling of silk when
one piece is folded over another; but this statement is discredited by
the most trustworthy observers.
Mrs. Somerville’s description is worth quoting, as taking up more
emphatically some points to which we have already alluded:--
The aurora, she says, is decidedly an electrical (or, more strictly
speaking, a magneto-electrical) phenomenon. It generally appears
soon after sunset in the form of a luminous arc stretching more or
less from east to west, the most elevated point being always in the
magnetic meridian of the place of the observer; across the arc the
coruscations are rapid, vivid, and of various colours, darting like
lightning to the zenith, and at the same time flitting laterally with
incessant velocity. The brightness of the rays varies in an instant;
they sometimes surpass the splendour of stars of the first magnitude,
and often exhibit colours of admirable transparency,--blood-red at
the base, emerald-green in the middle, and clear yellow towards
their extremity. Sometimes one, and sometimes a quick succession of
luminous currents run from one end of the arc or bow to the other, so
that the rays rapidly increase in brightness; but it is impossible
to say whether the coruscations themselves are actually affected by
a horizontal motion of translation, or whether the more vivid light
is conveyed from ray to ray. The rays occasionally dart far past the
zenith, vanish, suddenly reappear, and, being joined by others from the
arc, form a magnificent corona or immense dome of light. The segment of
the sky below the arc is quite black, as if formed by dense clouds; yet
M. Struve is said to have seen stars in it, and so it would appear that
the blackness of which several observers speak must be the effect of
contrast. The lower edge of the arc is evenly defined; its upper margin
is fringed by the coruscations, their convergence towards the north,
and that of the arc itself, being probably an effect of perspective.
The aurora exercises a remarkable influence on the magnetic needle,
even in places where the display is not visible. Its vibrations seem
to be slower or quicker according as the auroral light is quiescent or
in motion, and the variations of the compass during the day show that
the aurora is not peculiar to night. It has been ascertained by careful
observations that the disturbances of the magnetic needle and the
auroral displays were simultaneous at Toronto, in Canada, on thirteen
days out of twenty-four, the remaining days having been clouded; and
contemporaneous observations show that in these thirteen days there
were also magnetic disturbances at Prague and Tasmania; so that the
occurrence of auroral phenomena at Toronto on these occasions may be
viewed as a local manifestation connected with magnetic effects, which,
whatever may have been their origin, probably prevailed _on the same
day over the whole surface of the globe_.
Among the _atmospheric_ phenomena of the outer world we are
justified in reckoning the Winds, which are remarkable for their
variability. Their force is considerably diminished when they pass over
a wide surface of ice; sometimes the ice seems even to beat back the
breeze, and turn it in a contrary direction. The warm airs from the
south grow cool as they sweep across the frozen expanse, and give up
their moisture in the form of snow. In a region so bleak and chill it
is not often that clouds are created, the atmospheric vapours being
condensed into snow or hail without passing through any intermediate
condition.
Whirlwinds of frozen snow are formidable enemies to the seaman forced
to traverse the ice on foot, or in a sledge drawn by Eskimo dogs. Dense
showers lash and sting the unfortunate traveller’s face, penetrate his
mouth and nostrils, freeze together his very eyelids, and almost blind
him. His skin assumes a bluish tint, and burns as if scarred by the
keen thongs of a knout.
An optical illusion of frequent occurrence in the Polar Regions makes
objects appear of dimensions much larger than they really possess. A
fox assumes the proportions of a bear; low banks of ice are elevated
into lofty mountains. The eye is fatigued by dwelling upon the horizon
of lands which are never approached. Just as in the sandy deserts of
the Sahara the distances of real objects are apparently diminished, so
the Arctic explorer, misled by the aërial illusion, advances towards a
goal which seems always near at hand, but is never attained.
Another source of error, common both to the Arctic and the Tropical
deserts, is the mirage, a phenomenon of refraction, which represents
as suspended in air the images of remote objects, and thus gives rise
to the most curious illusions and fantastic scenes. Dr. Scoresby one
day perceived in the air the reversed representation of a ship which he
recognized as the _Fame_, commanded by his father. He afterwards
discovered that it had been lying moored in a creek about ten leagues
from the point where the mirage had played with his imagination.
Again, in approaching a field of ice or snow, the traveller invariably
descries a belt of resplendent white immediately above the horizon.
This is known as the “ice-blink,” and it reveals to the Arctic
navigator beforehand the character of the ice he is approaching. At
times, too, a range of icebergs, or of broken masses of ice, will be
reflected in colossal shadows on the sky, with a strange and even weird
effect.
But, after all, the special distinction between the Arctic lands and
the other regions of the globe is their long day and longer night.
Describing an immense spiral curve upon the horizon, the sun gradually
mounts to 30°, the highest point of its course; then, in the same
manner, it returns towards the horizon, and bids farewell to the
wildernesses of the North, slowly passing away behind the veil of a
gloomy and ghastly twilight.
When the navigator, says Captain Parry, finds himself for the first
time buried in the silent shadows of the Arctic night, he cannot
conquer an involuntary emotion of dread; he feels transported out of
the sphere of ordinary, commonplace existence. The deadly and sombre
deserts of the Pole seem like those uncreated voids which Milton has
placed between the realms of life and death. The very animals are
affected by the profound melancholy which saddens the face of Nature.
[Illustration: ATMOSPHERIC PHENOMENON IN THE ARCTIC
REGIONS:--REFLECTION OF ICEBERGS.]
Who can read without emotion the following passages from Dr. Kane’s
Journal?--
“_October 28, Friday._--The moon has reached her greatest northern
declination of about 25° 35’. She is a glorious object; sweeping around
the heavens, at the lowest part of her curve she is still 14° above the
horizon. For eight days she has been making her circuit with nearly
unvarying brightness. It is one of those sparkling nights that bring
back the memory of sleigh-bells and songs and glad communings of hearts
in lands that are far away.
“The weather outside is at 25° below zero.”
A few days later, and the heroic explorer writes:--
“_November 7, Monday._--The darkness is coming on with insidious
steadiness, and its advances can be perceived only by comparing one
day with its fellow of some time back. We still read the thermometer
at noonday without a light, and the black masses of the hills are
plain for about five hours with their glaring patches of snow; but all
the rest is darkness. Lanterns are always on the spar-deck, and the
lard-lamps never extinguished below. The stars of the sixth magnitude
shine out at noonday.
“Our darkness has ninety days to run before we shall get back again
even to the contested twilight of to-day. Altogether, our winter will
have been sunless for one hundred and forty days.”
Here is another significant passage; yet all its significance can
scarcely be appreciated by the dwellers in temperate climes:--
“_November 27, Sunday._--The thermometer was in the neighbourhood
of 40° _below zero_, and the day was too dark to read at noon.”
“_December 15, Thursday._--We have lost the last vestige of our
mid-day twilight. We cannot see print, and hardly paper: the fingers
cannot be counted a foot from the eyes. Noonday and midnight are alike;
and, except a vague glimmer on the sky that seems to define the hill
outlines to the south, we have nothing to tell us that this Arctic
world of ours has a sun.”
On the 11th of January (1854), Dr. Kane’s thermometer stood at 49°
below zero; and on the 20th the range of those at the observatory
was at -64° to -67°. On the 5th of February they began to show an
unexampled temperature. They ranged from 60° to 75° below zero, and one
very admirable instrument on the taffrail of the brig stood at -65°.
The reduced mean of the best spirit-standards gave -67°, or 97° below
the freezing-point of water.
At these temperatures chloric ether became solid, and carefully
prepared chloroform exhibited a granular film or pellicle on its
surface. Spirit of naphtha froze at -54°, and oil of sassafras at -49°.
The oil of winter-green assumes a flocculent appearance at -56°, and
solid at -63° and -65°.
Some further details, borrowed from Dr. Kane’s experiences, will
illustrate still more powerfully the singular atmospheric conditions of
the Arctic winter.
The exhalations from the surface of the body invested any exposed or
partially-clad part with a wreath of vapour. The air had a perceptible
pungency when inspired, but Dr. Kane did not undergo the painful
sensation described by some Siberian travellers. When breathed for any
length of time it imparted a sensation of dryness to the air-passages;
and Dr. Kane observed that all his party, as it were involuntarily,
breathed gradually, and with compressed lips.
It was at noon on the 21st of January that the first glimmer of
returning light became visible, the southern horizon being touched
for a short time with a distinct orange hue. The sun had, perhaps,
afforded them a kind of illumination before, but if so, it was not to
be distinguished from the “cold light of stars.” They had been nearing
the sunshine for thirty-two days, and had just reached that degree of
mitigated darkness which made the extreme midnight of Sir Edward Parry
in lat. 74° 47’.
We have already alluded to the depressing influence exercised by
the prolonged and intense darkness of the Arctic night, and we have
referred to the singular effect it has upon animals. Dr. Kane’s dogs,
though most of them were natives of the Arctic Circle, proved unable
to bear up against it. Most of them died from an anomalous form of
disease, to which the absence of light would seem to have contributed
as much as the extreme cold. This circumstance seems worthy of fuller
notice, and we quote, therefore, Dr. Kane’s observation upon it:--
“_January 20._--This morning at five o’clock--for I am so
afflicted with the _insomnium_ of this eternal night, that I
rise at any time between midnight and noon--I went upon deck. It was
absolutely dark, the cold not permitting a swinging lamp. There was not
a glimmer came to me through the ice-crusted window-panes of the cabin.
While I was feeling my way, half puzzled as to the best method of
steering clear of whatever might be before me, two of my Newfoundland
dogs put their cold noses against my hand, and instantly commenced
the most exuberant antics of satisfaction. It then occurred to me how
very dreary and forlorn must these poor animals be, at atmospheres
+10° in-doors and -50° without,--living in darkness, howling at an
accidental light, as if it reminded them of the moon,--and with
nothing, either of instinct or sensation, to tell them of the passing
hours, or to explain the long-lost daylight.”
The effect of the prolonged darkness upon these animals was most
extraordinary. Every attention was paid to their wants; they were kept
below, tended, fed, cleansed, caressed, and _doctored_; still they
grew worse and worse. Strange to say, their disease was as clearly
_mental_ as in the case of any human being. There was no physical
disorganization; they ate voraciously; they slept soundly, they
retained their strength. But first they were stricken by epilepsy, and
this was followed by true lunacy. They barked frenziedly at nothing;
they walked in straight and curved lines with anxious and unwearying
perseverance. They fawned on the seamen, but without seeming to
appreciate any caresses bestowed upon them; pushing their head against
the friend who noticed them, or oscillating with a strange pantomime of
fear. Their most intelligent actions seemed of an automatic character;
sometimes they clawed at their masters, as if seeking to burrow into
their seal-skins; sometimes they preserved for hours a moody silence,
and then started off howling, as if pursued, and ran to and fro for a
considerable period.
When spring returned Dr. Kane had to mourn the loss of nine splendid
Newfoundland and thirty-five Eskimo dogs; of the whole pack only six
survived, and one of these was unfit for draught.
Having dwelt at some length on the characteristics of the Arctic
winter, we now turn to consider those of the Arctic spring. This
begins in April, but does not exhibit itself in all the freshness of
its beauty until May. The temperature rises daily in the interval; the
winter fall of snow, which has so long shrouded the gaunt hills and
lain upon the valleys, rolls up before the rays of the rising sun;
and the melted snow pours in noisy torrents and flashing cascades
through the rugged ravines and over the dark sides of the lofty cliffs:
everywhere the air resounds with the din of falling waters. Early in
June the traveller sees with delight the signs of returning vegetation.
The willow-stems grow green with the fresh and living sap; mosses,
and poppies, and saxifrages, and the cochlearia, with other hardy
plants, begin to sprout; the welcome whirr of wings is brought upon the
breeze; the cliffs are alive with the little auks; flocks of stately
eider-ducks sail into the creeks and sounds; the graceful terns scream
and dart over the sea; the burgomasters and the gyrfalcons move to and
fro with greater dignity; the long-tailed duck fills the echoes with
its shrill voice; the snipes hover about the fresh-water pools; the
sparrows chirp from rock to rock; long lines of cackling geese sail in
the blue clearness overhead on their way to a remoter north; the walrus
and the seal bask on the ice-floes which have broken up into small
rafts, and drift lazily with the currents; and a fleet of icebergs move
southwards in solemn and stately procession, their spires and towers
flashing and coruscating in the sunlight.
[Illustration: ADVENT OF SPRING IN THE POLAR REGIONS.]
We transcribe a sketch of a spring landscape in the Polar world from
the pages of Dr. Hayes:--
We arrived at the lake, he says, in the midst of a very enlivening
scene. The snow had mainly disappeared from the valley, and, although
no flowers had yet appeared, the early vegetation was covering the
banks with green, and the feeble growths opened their little leaves
almost under the very snow, and stood alive and fresh in the frozen
turf, looking as glad of the spring as their more ambitious cousins of
the warm South. Numerous small herds of reindeer had come down from the
mountains to fatten on this newly budding life. Gushing rivulets and
fantastic waterfalls mingled their pleasant music with the ceaseless
hum of birds, myriads of which sat upon the rocks of the hill-side,
or were perched upon the cliffs, or sailed through the air in swarms
so thick that they seemed like a dark cloud passing before the sun.
These birds were the little auk, a water-fowl not larger than a quail.
The swift flutter of their wings and their constant cry filled the air
with a roar like that of a storm advancing among the forest trees.
The valley was glowing with the sunlight of the early morning, which
streamed in over the glacier, and robed hill, mountain, and plain in
brightness.
Spring passes into summer, and all nature seems endowed with a new
life. The death-like silence, the oppressive darkness, the sense of
fear and despondency, all have passed away; and earth and water echo
with cheerful voices, the landscape is bathed in a glorious radiance,
the human soul is conscious of a sentiment of hope and expectation. The
winter is past and gone; the flowers appear on the earth; the time of
the singing of birds is come. The snow has melted from the hills, and
the streams run with a merry music, and the scanty flora of the far
northern world attains its full development. By day and night the sun
pours forth its invigorating rays, and even the butterfly is encouraged
to sport among the blossoms. The Aurora no longer exhibits its
many-coloured fires, and the sky is as clear and cloudless as in genial
Italy. But this season of life and warmth is of short duration, and
when July has passed the sun begins to sink lower and lower, as if to
visit another world; a shadow gradually steals over the sky; winds blow
fiercely, and bring with them blinding showers of sleet and icicles;
the fountains and the streams cease their pleasant flow; the broad
crust of ice spreads over the imprisoned sea; the snow-mantle rests on
the hill-sides and the valleys; the birds wing their way to the warmer
South; and the Polar world is once more given over to the silence, the
loneliness, and the gloom of the long Arctic night.
Turning our attention now to the “starry heavens,” we observe that
conspicuous among the glorious host is the North Star, which, from
earliest times, has been the friend and guide of the navigator.
The Pole-Star, or Polaris, is the star α in the constellation of
_Ursa Minor_, and is the nearest large star to the north pole
of the celestial equator. We say the “nearest,” because it does not
actually mark the position of the pole, but is about 1° 30’ from it.
Owing, however, to the motion of the pole of the celestial equator
round that of the ecliptic, it will, in about 2000 A.D.,
approach within 28’ of the north pole; but after reaching this point
of approximation it will begin to recede. At the time of Hipparchus it
was 12° distant from it (that is, in 156 B.C.); in 1785, 2°
2’. You may easily find its place in the “stellar firmament,” for a
line drawn between the stars α and β (hence called the “Pointers”) of
the constellation _Ursa Major_, or the Great Bear, and produced in
a northerly direction for about four and a half times its own length,
will almost touch the Pole-Star. Two thousand years this post of
honour, so to speak, was occupied by the star β of _Ursa Major_;
while, in about twelve thousand years, it will be occupied by the star
Vega in _Lyra_, which will be within 5° of the north pole.
The constellation of _Ursa Major_ is always above the horizon of
Europe, and hence it has been an object of curiosity to its inhabitants
from the remotest antiquity. Our readers may easily recognize it by
three stars which form a triangle in its tail, while four more form
a quadrangle in the body of the imaginary bear. In the triangle,
the first star at the tip of the tail is Benetnasch of the second
magnitude; the second, Mizar; and the third, Alioth. In the quadrangle,
the first star at the root of the tail is named Megrez; the second
below it, Phad; the third, in a horizontal direction, Merak; and the
fourth, above the latter, Dubhe, of the first magnitude.
[Illustration: URSA MAJOR AND URSA MINOR.]
In _Ursa Minor_ the only conspicuous star is Polaris, of which we
have recently spoken.
We subjoin a list of the northern constellations, including the names
of those who formed them, the number of their visible stars, and the
names of the most important and conspicuous.

A few remarks in reference to some of these constellations, and the
glorious orbs which they help to indicate to mortal eyes, may fitly
close this chapter.
We have already alluded to _Ursa Major_, which forms one of
the most conspicuous objects of the northern heavens. It has borne
different names, at different times, and among different peoples.
It was the Ἄρκτος μεγάλη of the Greeks; the “Septem triones” of the
Latins. It is known in some parts as David’s Chariot; the Chinese call
it, _Tcheou-pey_.
Night and day this constellation watches above the northern horizon,
revolving, with slow and majestic march, around Polaris, in four
and twenty hours. The quadrangle of stars in the body of the Great
Bear forms the wheels of the chariot; the triangle in its tail, the
chariot-pole. Above the second of the three latter shines the small
star Alcor, also named the Horseman. The Arabs call it Saidak, or “the
Test,” because they use it to try the range and strength of a person’s
vision.
This brilliant northern constellation, composed, with the exception of
δ, of stars of the second magnitude, has frequently been celebrated by
poets. We may paraphrase, for the advantage of our readers, a glowing
apostrophe from the pen of the American Ware:--
With what grand and majestic steps, he says, it moves forward in its
eternal circle, following among the stars its regal way in a slow
and silent splendour! Mighty creation, I salute thee! I love to see
thee wandering in the shining paths like a giant proud of his strong
girdle--severe, indefatigable, resolved--whose feet never lag in the
road which lies before them. Other tribes abandon their nocturnal
course and rest their weary orbs under the waves; but thou, thou
never closest thy burning eyes, and never suspendest thy determined
steps. Forward, ever forward! While systems change, and suns retire,
and worlds fall to sleep and awake again, thou pursuest thy endless
march. The near horizon attempts to check thee, but in vain. A watchful
sentinel, thou never quittest thy age-long duty; but, without allowing
thyself to be surprised by sleep, thou guardest the fixed light of the
universe, and preventest the north from ever forgetting its place.
Seven stars dwell in that shining company; the eye embraces them all
at a single glance; their distances from one another, however, are
not less than the distance of each from Earth. And this again is the
reciprocal distance of the celestial centres or foci. From depths of
heaven, unexplored by thought, the piercing rays dart across the void,
revealing to our senses innumerable worlds and systems. Let us arm
our vision with the telescope, and let us survey the firmament. The
skies open wide; a shower of sparkling fires descends upon our head;
the stars close up their ranks, are condensed in regions so remote
that their swift rays (swifter than aught else in creation) must
travel for centuries before they can reach our Earth. Earth, sun, and
ye constellations, what are ye among this infinite immensity and the
multitude of the Divine works!
If we face towards the Pole-Star, which, as we have seen, preserves
its place in the centre of the northern region of the sky, we have the
south behind us, the east is on our right, the west upon our left. All
the stars revolving round the Pole-Star, from right to left, should be
recognized according to their mutual relations rather than referred
to the cardinal points. On the other side of Polaris, as compared
with the Great Bear, we find another constellation which is easily
recognized. If from the central star δ we carry a line to the Pole, and
then prolong it for an equal distance, we traverse the constellation
of _Cassiopeia_, composed of five stars of the third magnitude,
disposed somewhat like the outer jambs of the letter M. The small star
χ, terminating the square, gives it also the form of a chair. This
group occupies every possible situation in revolving round the Pole,
being at one time above it, at another below, now on the left, and then
on the right; but it is always readily found, because, like _Ursa
Major_, to which it is invariably opposite, it never sets. The
Pole-Star is the axle round which these two constellations revolve.
If we now draw, from the stars α and δ in _Ursa Major_, two
lines meeting at the Pole, and afterwards extend them beyond
_Cassiopeia_, they will abut on the square of _Pegasus_,
which is bounded on one of its sides by a group, or series, of three
stars resembling the triangle in _Ursa Major_. These three belong
to the constellation of _Andromeda_ (α, β, and γ), and themselves
abut on another three-orbed group, that of _Perseus_.
The last star in the square of _Perseus_ is also the first α of
_Andromeda_: the other three are named, Algenib, γ; Markab, α;
and Scheat, β. To the north of _Andromeda_ β, and near a small
star, ν, the Arctic traveller will discern an oblong nebula, which
may be compared to the light of a taper seen through a sheet of horn;
this is the first nebula to which any allusion occurs in the annals
of astronomy. In _Perseus_ α, an orb of great brilliancy, on the
prolonged plane of the three principal stars of _Andromeda_,
shines with steady lustre between two less dazzling spheres, and forms
in conjunction with them a concave arc very easily distinguished.
Of this arc we may avail ourselves as a new point of departure. By
prolonging it in the direction of δ, we come to a very bright star of
the first magnitude, the _Goat_. By forming a right angle to this
prolongation in a southerly direction we come to that glorious mass of
stars, not very frequently above the Polar horizon, the _Pleiads_.
These were held in evil repute among the ancients. Their appearance was
supposed to be ominous of violent storms, and Valerius Flaccus speaks
of them as fatal to ships.
[Illustration: NEBULA IN ANDROMEDA.]
Algol, or Medusa’s Head, known to astronomers as Perseus β, belongs
to the singular class of Variable Stars. Instead of shining with a
constant lustre, like other orbs, it is sometimes very brilliant,
and sometimes very pale; passing, apparently, from the second to the
fourth magnitude. According to Goodricke, its period of variation is 2
days 20 hours 48 minutes. This phenomenal character was first observed
by Maraldi in 1694; but the duration of the change was determined by
Goodricke in 1782. For two days and fourteen hours it continues at
its brightest, and shines a glory in the heavens. Then its lustre
suddenly begins to wane, and in three hours and a half is reduced to
its minimum. Its weakest period, however, does not last more than about
fifteen minutes. It then begins to increase in brightness, and in
three hours and a half more it is restored to its full splendour; thus
passing through its succession of changes in 2 days 20 hours 48 minutes.
This singular periodicity suggested to Goodricke the idea of some
opaque body revolving around the star, and by interposing between it
and the Earth cutting off a portion of its light. Algol is one of the
most interesting of the welcome stars which kindle in the long Arctic
darkness.
The star ζ in _Perseus_, situated above the “stormy Pleiads,” is
double; that is, a binary star. ξ in Ursa Major is also a twin-star;
and so is Polaris, the second and smaller star appearing a mere speck
in comparison with its companion.

These are the principal stars and starry groups in the Circumpolar
Regions of the heavens, on one side; let us now turn our attention to
the other.
For this purpose we must again take the Great Bear as our
starting-point. Prolonging the tail in its curvature, the Arctic
traveller notes, at some distance from it, a star of the first
magnitude, Arcturus, or Boötes α. This star, though without any
authority, was at one time considered the nearest to the Earth of all
the starry host. About 10° to the north-east of it is Mirac, or ε
Boötes; one of the most beautiful objects in the heavens, on account of
the contrasted hues, yellow and azure, of the two stars composing it.
Unfortunately, the twin-orbs cannot be distinctly seen except with a
telescope of two hundred magnifying power.
A small ring of stars to the left of Boötes is appropriately known as
_Corona Borealis_, or the Northern Crown.
The constellation of _Boötes_ forms a pentagon; and the stars
composing it are all of the third magnitude, with the exception of
α, which is of the first. Arcturus, as we have said, was anciently
considered the star nearest to the Earth. It is, at all events,
_one_ of the nearest, and belongs to the small number of those
whose distance our astronomers have succeeded in calculating. It is 61
trillions, 712,000 millions of leagues from our planet; a distance of
which we can form no appreciable conception. Moreover, it is a coloured
star; on examining it through a telescope we see that it is of the same
hue as the “red planet Mars.”
By carrying a line from the Polar Star to Arcturus, and raising
a perpendicular in the middle of this line, opposite to _Ursa
Major_, the observer of the Arctic skies will discover one of the
most luminous orbs of night, _Vega_, or α Lyra, near the Milky
Way. The star β Lyra, or Sheliak, is a variable star, changing from
the third to the fifth magnitude, and accomplishing its variation in 6
days 10 hours and 34 minutes. β and ε Lyra are quadruple systems, each
composed of binary or twin-stars.
The line drawn from Arcturus to Vega cuts the constellation of Hercules.
Between Ursa Major and Ursa Minor may be observed a prolonged series
of small stars, coiling, as it were, in a number of convolutions,
and extending towards Vega: these belong to the constellation of the
_Dragon_.
Such are the principal objects which attract the attention of the
traveller, when contemplating the star-studded firmament of the Arctic
night.
