It seems strange that the plants above-named and many others should

spring only from the dry sand of the dunes, but the apparent riddle

is solved when we know that it is only the sand thus piled up, that

becomes sufficiently warmed in the months of uninterrupted sunshine

for these plants to flourish. Nowhere else throughout the tundra is

this the case. Moor and bog, morass and swamp, even the lakes with

water several yards in depth only form a thin summer covering over

the eternal winter which reigns in the tundra, with destructive as

well as with preserving power. Wherever one tries to penetrate to any

depth in the soil one comes--in most cases scarcely a yard from the

surface--upon ice, or at least on frozen soil, and it is said that one

must dig about a hundred yards before breaking through the ice-crust

of the earth. It is this crust which prevents the higher plants from

vigorous growth, and allows only such to live as are content with

the dry layer of soil which thaws in summer. It is only by digging

that one can know the tundra for what it is: an immeasurable and

unchangeable ice-vault which has endured, and will continue to endure,

for hundreds of thousands of years. That it has thus endured is proved

indisputably by the remains of prehistoric animals embedded in it, and

thus preserved for us. In 1807 Adams dug from the ice of the tundras

the giant mammoth, with whose flesh the dogs of the Yakuts sated their

hunger, although it must have died many thousands of years before,

for the race became extinct in the incalculably distant past. The icy

tundra had faithfully preserved the carcase of this primitive elephant

all through these hundreds of thousands of years.[8]

Many similar animals, and others of a more modern time, are embedded

in the ice, though it is not to be supposed that the tundra was ever

able to sustain a much richer fauna than it has now. Bison and musk-ox

traversed it long after the time of the mammoth; giant-elk and moose

belonged to it once. Now its animal life is as poor and monotonous as

its vegetation--as itself. This holds true, however, only with regard

to species, not to individuals, for the tundra is, at least in summer,

the home of numerous animals.

The year is well advanced before the tundra begins to be visibly

peopled. Of the species which never leave it one sees very little in

winter. The fish which ascend its rivers from the sea are concealed by

the ice; the mammals and birds which winter in it are hidden by the

snow, under which they live, or whose colour they wear. Not until the

snow begins to melt on the southern slopes does the animal life begin

to stir. Hesitatingly the summer visitors make their appearance. The

wolf follows the wild reindeer, the army of summer birds follows the

drifting ice blocks on the streams. Some of the birds remain still

undecided in the regions to the South, behave as if they would breed

there, then suddenly disappear from their resting-place by the way, fly

hastily to the tundra, begin to build directly on their arrival, lay

their eggs, and brood eagerly, as though they wished to make up for

the time gained by their relatives in the South. Their summer life is

compressed into few weeks. They arrive already united, paired for life,

or at least for the summer; their hearts stirred by all-powerful love,

they proceed, singing and rejoicing, to build a nest; unceasingly they

give themselves up to their parental duties, brood, rear, and educate

their young, moult, and migrate abroad again.

[Illustration: Fig. 7.--The White or Arctic Fox (_Canis lagopus_).]

The number of species which may be looked upon as native to the tundra

is small indeed, yet it is much greater than that of those which may

be regarded as characteristic of the region. As the first of these, I

should like to place the Arctic fox. He ranges over the whole extent

of the tundra, and is sure of maintenance and food in the south at

least, where he occurs along with our fox and other allied species.

Like some other creatures he wears the colours of his home, in summer

a rock-coloured dress, in winter a snow-white robe, for the hairs

of his thick fur coat are at first stone-gray or grayish-blue, and

become snow-white in winter.[9] He struggles through life with ups

and downs like other foxes, but his whole character and conduct are

quite different from those of our reynard and his near relatives. One

scarcely does him injustice in describing him as a degenerate member of

a distinguished family, unusually gifted, intelligent, and ingenious.

Of the slyness and ingenuity, the calculating craft, the never-failing

presence of mind of his congeners he evinces hardly any trace. His

disposition is bold and forward, his manner officious, his behaviour

foolish. He may be a bold beggar, an impudent vagabond, but he is

never a cunning thief or robber, weighing all circumstances, and using

all available means to attain his end. Unconcernedly he stares at the

huntsman’s gun; unwarned by the ball, which passes whistling over his

body, he follows his worst enemy; unhesitatingly he forces his way into

the birch-bark hut of the wandering reindeer-herdsmen; without fear he

approaches a man sleeping in the open, to steal the game he has caught,

or even to snap at a naked limb. On one occasion an Arctic fox at which

I had several times fired in vain in the dusk, kept following my steps

like a dog. My old sporting friend, Erik Swenson of Dovrefjeld, relates

that one night a fox nibbled the fur rug on which he lay, and old

Steller vouches for many other pranks which this animal plays, pranks

which every one would declare incredible were they not thoroughly

guaranteed by corroborating observations. An insufficient knowledge of

human beings, so sparsely represented in the tundra, may to some extent

account for the extraordinary behaviour of this fox, but it is not the

only reason. For neither the red fox nor any other mammal of the tundra

behaves with so little caution; not even the lemming approaches him in

this respect.

A strange creature certainly is this last inhabitant of our region

whatever species of his family we consider. He, or at least his tracks,

may be seen everywhere throughout the tundra. The tracks run in all

directions, often through places overgrown by dwarf-birches, narrow,

smooth, neatly-kept paths in the moss, going straight for several

hundred yards, then diverging to right or left, and only returning to

the main path after many circuits. On these we may often see, in great

numbers during a dry summer, a little, short-tailed, hamster-like

animal nimbly pattering along and soon disappearing out of sight. This

is the lemming, a rodent smaller than a rat, but larger than a mouse,

and with brightly but irregularly marked skin, usually brown, yellow,

gray, and black. If we dissect the animal we see, not without surprise,

that it consists almost entirely of skin and viscera. Its bones and

muscles are fine and tender; its viscera, especially the alimentary

and the reproductive organs, are enormously developed. This state of

things explains some phenomena of its life which were long considered

unintelligible: the almost abrupt occurrence of well-nigh unlimited

fertility, and the vast, apparently organized migrations of the animal.

In ordinary circumstances the lemming leads a very comfortable life.

Neither in summer nor in winter has he any anxiety about subsistence.

In winter he devours all sorts of vegetable matter,--moss-tips,

lichen, and bark; in summer he lives in his burrow, in winter in

a warm, thick-walled, softly-lined nest. Danger indeed threatens

from all sides, for not only beasts and birds of prey, but even the

reindeer devour hundreds and thousands of lemmings;[10] nevertheless

they increase steadily and rapidly, until special circumstances arise

when millions, which have come into existence within a few weeks, are

annihilated within a few days. Spring sets in early, and a more than

usually dry summer prevails in the tundra. All the young of the first

litter of the various lemming females thrive, and six weeks later, at

the most, these also multiply. Meantime the parents have brought forth

a second and a third litter, and these in their turn bring forth young.

Within three months the heights and low grounds of the tundra teem with

lemmings, just as our fields do with mice under similar circumstances.

Whichever way we turn, we see the busy little creatures, dozens at a

single glance, thousands in the course of an hour. They run about on

all the paths and roads; driven to extremity, they turn, snarling and

sharpening their teeth, on the defensive even against man, as if their

countless numbers lent to each individual a defiant courage. But the

countless and still-increasing numbers prove their own destruction.

Soon the lean tundra ceases to afford employment enough for their

greedy teeth. Famine threatens, perhaps actually sets in. The anxious

animals crowd together and begin their march. Hundreds join with

hundreds, thousands with other thousands: the troops become swarms, the

swarms armies. They travel in a definite direction, at first following

old tracks, but soon striking out new ones; in unending files--defying

all computation--they hasten onwards; over the cliffs they plunge into

the water. Thousands fall victims to want and hunger; the army behind

streams on over their corpses; hundreds of thousands are drowned in

the water, or are shattered at the foot of the cliffs; the remainder

speed on; other hundreds and thousands fall victims to the voracity of

Arctic and red foxes, wolves and gluttons, rough-legged buzzards and

ravens, owls and skuas which have followed them; the survivors pay no

heed. Where these go, how they end, none can say, but certain it is

that the tundra behind them is as if dead, that a number of years pass

ere the few who have remained behind, and have managed to survive,

slowly multiply, and visibly re-people their native fields.[11]

[Illustration: Fig. 8.--The Reindeer (_Tarandus rangifer_).]

A third animal characteristic of the tundra is the reindeer. Those who

know this deer, in itself by no means beautiful, only in a state of

captivity and slavery, can form no idea of what it is under natural

conditions. Here in the tundra one learns to appreciate the reindeer,

to recognize and value him as a member of a family which he does not

disgrace. He belongs to the tundra, body and soul. Over the immense

glacier and the quivering crust of the unfathomable morass, over

the boulder-heaps and the matted tops of the dwarf-birches or over

the mossy hillocks, over rivers and lakes he runs or swims with his

broad-hoofed, shovel-like, extraordinarily mobile feet, which crackle

at every step. In the deepest snow he uses his foot to dig for food.

He is protected against the deadly cold of the long northern night

by his thick skin, which the arrows of winter cannot pierce, against

the pangs of hunger by the indiscriminateness of his appetite. From

the wolf, which invariably follows close on his heels, he is, in some

measure at least, saved by the acuteness of his senses, by his speed

and endurance. He passes the summer on the clear heights of the tundra,

where, on the slopes just beside the glaciers, the soil, belted over

with reindeer-moss, also brings forth juicy, delicate alpine plants;

in winter he ranges through the low tundra from hill to hill seeking

spots from which the snow has been cleared off by the wind.[12] Shortly

before this, having attained to his full strength and fully grown his

branching antlers, he had in passionate violence engaged in deadly

combat with like-minded rivals as strong as himself until the still

tundra resounded with the clashing of their horns. Now, worn out with

fighting and with love, he ranges peacefully through his territory with

others of his kind, associated in large herds, seeking only to maintain

the struggle with winter. The reindeer is certainly far behind the stag

in beauty and nobility, but when one sees the great herds, unhampered

by the fetters of slavery, on the mountains of their native tundra, in

vivid contrast to the blue of the sky and the whiteness of the snowy

carpet, one must acknowledge that he, too, takes rank among noble wild

beasts, and that he has more power than is usually supposed to quicken

the beating of the sportsman’s heart.

The tundra also possesses many characteristic birds. Whoever has

traversed the northern desert must have met one, at least, of these,

the ptarmigan:

“In summer gay from top to toe,

In winter whiter than the snow”.

I do not allude to the ptarmigan of our mountains, which is here

also restricted to the glacier region, but to the much more abundant

willow-grouse. Wherever the dwarf-birch thrives it is to be found, and

it is always visible, but especially when the silence of night has

fallen upon the tundra, even though the sun be shining overhead. It

never entirely forsakes its haunts, but, at the most, descends from

the heights to the low grounds in winter. It is lively and nimble,

pert and self-possessed, jealous and quarrelsome towards its rivals,

affectionate and devoted towards its mate and young. Its life resembles

that of our partridge, but its general behaviour has a much greater

charm. It is the embodiment of life in the desert. Its challenging

call rings out through the still summer night, and the coveys enliven

the wintry tundra, forsaken by almost all other birds. Its presence

gladdens and charms naturalist and sportsman alike.

During summer the golden plover, which also must be described as a

faithful child of the tundra, is to be met almost everywhere. As the

swift ostrich to the desert, the sand-grouse to the steppes, the

rock-partridge to the mountains, the lark to the corn-fields, so the

golden plover belongs to the tundra. Gay as its dress may be, they are

the colours of the tundra which it wears; its melancholy cry is the

sound most in keeping with this dreary region. Much as we like to see

it in our own country, we greet it without pleasure here, for its cry

uttered day and night makes us as sad as the tundra itself.

With much greater pleasure does one listen to the voice of another

summer guest of the region. I do not refer to the tender melodies

of the blue-throated warbler, which is here one of the commonest of

brooding birds and justly named the “hundred-tongued singer”, nor to

the ringing notes of the fieldfare, which also extends to the tundra,

nor to the short song of the snow bunting, nor to the shrill cries of

the peregrine falcon or the rough-legged buzzard, nor to the exultant

hooting of the sea-eagle or the similar cry of the snowy owl, nor

to the resounding trumpet-call of the musical swan or the plaintive

bugle-like note of the Arctic duck, but to the pairing and love cry of

one or other of the divers--a wild, unregulated, unrestrained, yet

sonorous and tuneful, resonant and ringing northern melody, comparable

to the roar of the surge or to the thunder of a waterfall as it rushes

to the deep. Wherever a lake rich in fish is to be found, with a secret

place in the reeds thick enough to conceal a floating nest, we find

these children of the tundra and the sea, these soberly-joyous fishers

in the calm fresh waters and fearless divers in the northern sea.

Thence they have come to the tundra to brood, and back thither they

will lead their young as soon as these are able, like themselves, to

master the waves. Over the whole extent of the tundra they visit its

waters, but they prefer to the broad inland lakes the little ponds on

the hills along the coast, whence they can daily plunge, with their

wildly jubilant sea song, into the heaving, bountiful ocean, which is

their home.

From the sea come other two birds very characteristic of the tundra.

The eye follows every movement of the robber-gulls with real delight,

of the phalarope with actual rapture. Both breed in the tundra: the

one on open mossy moors, the other on the banks of the most hidden

ponds and pools among the sallows. If other gulls be the “ravens of the

sea” the skuas may well be called the “sea-falcons”. With full justice

do they bear the names of robber and parasitic gulls, for they are

excellent birds of prey when there is no opportunity for parasitism,

and they become parasites when their own hunting has been unsuccessful.

Falcon-like they fly in summer through the tundra, in winter along

the coast regions of the North Sea; they hover over land or sea to

find their prey, then swoop down skilfully and gracefully and seize

without fail the victim they have sighted. But even these capable

hunters do not scruple, under some circumstances, to become bold

beggars. Woe to the gull or other sea-bird which seizes its prey within

sight of a skua! With arrow-like swiftness he follows the fortunate

possessor uttering barking cries, dances, as if playfully, round him

on all sides, cunningly prevents any attempt at flight, resists all

defence, and untiringly and ceaselessly teases him till he gives up

his prize, even though it has to be regurgitated from his crop. The

life and habits of the Arctic skua, its skill and agility, its courage

and impudence, untiring watchfulness and irresistible importunity

are extraordinarily fascinating; even its begging can be excused, so

great are its charms. Yet the phalarope is still more attractive. It

is a shore bird, which unites in itself the qualities of its own order

and those of the swimming birds, living, as it does, partly on land,

partly in the water, even in the sea. Buoyant and agile, surpassing

all other swimming birds in grace of motion, it glides upon the waves;

quickly and nimbly it runs along the shore; with the speed of a snipe

it wings its zigzag flight through the air. Confidently and without

fear it allows itself to be observed quite closely, and in its anxiety

for the safety of its brood usually betrays its own nest, with the

four pear-shaped eggs, however carefully it has been concealed among

the reeds. It is perhaps the most pleasing of all the birds of the

tundra.[13]

[Illustration: Fig. 9.--Skuas, Phalarope, and Golden Plovers.]

Likewise characteristic of the tundra are the birds of prey, or, at

least, their manner of life there is characteristic. For it is only on

the southern boundary of the region or among the heights that there

are trees or rocks on which they can build their eyries, and they are

perforce obliged to brood on the ground. Among the winding branches of

the dwarf-birch is the nest of the marsh-owl, on its crown that of the

rough-legged buzzard; on the bare ground lie the eggs of the snowy-owl

and the peregrine falcon, though the latter chooses a place as near as

possible to the edge of a gully, as though he would deceive himself by

vainly attempting to make up for the lack of heights. That it and all

the others are fully conscious of the insecurity of their nesting-place

is shown by their behaviour on the approach of man. From a distance the

traveller is watched suspiciously and is greeted with loud cries; the

nearer he approaches the greater grows the fear of the anxious parents.

Hitherto they have been circling at a safe distance, about twice as far

as a shot would carry, over the unfamiliar but dreaded enemy; now they

swoop boldly down, and fly so closely past his head that he distinctly

hears the sharp whirr of their wings, sometimes indeed he has reason

to fear that he will be actually attacked. Meanwhile the young birds,

which are visible even from a distance as white balls, bend timidly

down and await the approach of this enemy,--suspected at least, if not

known as such,--sitting so still in their chosen, or perhaps forced

position that one can sketch them without fear of being disturbed by a

single movement--a charming picture!

Many other animals might be enumerated if I thought them necessary

to a picture of the tundra. At least one more is characteristic--the

mosquito. To call it the most important living creature of the tundra

would be scarcely an exaggeration. It enables not a few of the higher

animals, especially birds and fishes, to live; it forces others, like

man, to periodic wanderings; and it is in itself enough to make the

tundra uninhabitable in summer by civilized beings. Its numbers are

beyond all conception; its power conquers man and beast; the torture it

causes beggars description.

It is well known that the eggs of all mosquitoes are laid in the water,

and that the larvæ which creep forth in a few days remain in the water

till their metamorphosis is accomplished. This explains why the tundra

is more favourable than any other region to their development, and to

their occurrence in enormous numbers. As soon as the sun, once more

ascending, has thawed the snow, the ice, and the upper crust of the

earth, the life of the mosquito, latent in winter but not extinguished,

begins to stir again. The larvæ escape from the eggs which have been

buried, but not destroyed, in the frozen mud; in a few days these larvæ

become pupæ, the pupæ become winged insects, and generation follows

generation in quick succession. The heyday of the terrible pests lasts

from before the beginning of the summer solstice until the middle of

August.

During the whole of this time they are present on the heights as in the

low grounds, on the mountains or hills as in the valleys, among the

dwarf-birches and sallow bushes as on the banks of rivers and lakes.

Every grass-stalk, every moss-blade, every twig, every branch, every

little leaf sends forth hundreds and thousands of them all day long.

The mosquitoes of tropical countries, of the forests and marshes of

South America, the interior of Africa, India, and the Sunda islands,

so much dreaded by travellers, swarm only at night; the mosquitoes

of the tundra fly for ten weeks, for six of these actually without

interruption. They form swarms which look like thick black smoke; they

surround, as with a fog, every creature which ventures into their

domains; they fill the air in such numbers that one hardly dares to

breathe; they baffle every attempt to drive them off; they transform

the strongest man into an irresolute weakling, his anger into fear, his

curses into groans.

As soon as the traveller sets foot on the tundra their buzzing is

heard, now like the singing of a tea-kettle, now like the sound of

a vibrating metal rod, and, a few minutes later, he is surrounded

by thousands and thousands. A cloud of them swarms round head and

shoulders, body and limbs, follows his steps, however quickly he moves,

and cannot possibly be dispersed. If he remain standing, the cloud

thickens; if he move on, it draws itself out; if he run as quickly as

possible, it stretches into a long train, but does not remain behind.

If a moderate wind is blowing against them, the insects hasten their

flight to make headway against the current of air; when the wind

is more violent all the members of the swarm strain themselves to

the utmost so as not to lose their victim, and pounce like pricking

hailstones on head and neck. Before he knows, he is covered from head

to foot with mosquitoes. In a dense swarm, blackening gray clothes,

giving dark ones a strange spotted appearance, they settle down and

creep slowly about, looking for an unappropriated spot from which

to suck blood. They creep noiselessly and without being felt to the

unprotected face and neck, the bare hands and the feet covered only

with stockings, and a moment later they slowly sink their sting into

the skin, and pour the irritant poison into the wound. Furiously the

victim beats the blood-sucker to a pulp, but while the chastising

hand still moves, three, four, ten other gnats fasten on it, while

others begin work on the face, neck, and feet, ready to do exactly as

the slain ones had done. For when blood has once flowed, when several

insects have met their death on the same place, all the rest seek out

that very spot, even though the surface becomes gradually covered with

bodies. Specially favourite points of attack are the temples, the

forehead just under the hat-brim, the neck and the wrist, places, in

short, which can be least well protected.
