13. AURORA SEEN IN GREENLAND.
But of all the magnificent spectacles that relieve the monotonous gloom of the Arctic winter, there is none to equal the magical beauty of the Aurora. Night covers the snow-clad earth; the stars glimmer feebly through the haze which so frequently dims their brilliancy in the high latitudes, when suddenly a broad and clear bow of light spans the horizon in the direction where it is traversed by the magnetic meridian. This bow sometimes remains for several hours, heaving or waving to and fro, before it sends forth streams of light ascending to the zenith. Sometimes these flashes proceed from the bow of light alone; at others they simultaneously shoot forth from many opposite parts of the horizon, and form a vast sea of fire whose brilliant waves are continually changing their position. Finally they all unite in a magnificent crown or copula of light, with the appearance of which the phenomenon attains its highest degree of splendor. The brilliancy of the streams, which are commonly red at their base, green in the middle, and light yellow toward the zenith, increases, while at the same time they dart with greater vivacity through the skies. The colors are wonderfully transparent, the red approaching to a clear blood-red, the green to a pale emerald tint. On turning from the flaming firmament to the earth, this also is seen to glow with a magical light. The dark sea, black as jet, forms a striking contrast to the white snow-plain or the distant ice-mountain; all the outlines tremble as if they belonged to the unreal world of dreams. The imposing silence of the night heightens the charms of the magnificent spectacle.
But gradually the crown fades, the bow of light dissolves, the streams become shorter, less frequent, and less vivid; and finally the gloom of winter once more descends upon the northern desert.

The reindeer may well be called the camel of the northern wastes, for it is a no less valuable companion to the Laplander or to the Samojede than the “ship of the desert” to the wandering Bedouin. It is the only member of the numerous deer family that has been domesticated by man; but though undoubtedly the most useful, it is by no means the most comely of its race. Its clear, dark eye has, indeed, a beautiful expression, but it has neither the noble proportions of the stag nor the grace of the roebuck, and its thick square-formed body is far from being a model of elegance. Its legs are short and thick, its feet broad, but extremely well adapted for walking over the snow or on a swampy ground. The front hoofs, which are capable of great lateral expansion, curve upward, while the two secondary ones behind (which are but slightly developed in the fallow deer and other members of the family) are considerably prolonged: a structure which, by giving the animal a broader base to stand upon, prevents it from sinking too deeply into the snow or the morass. Had the foot of the reindeer been formed like that of our stag, it would have been as unable to drag the Laplander’s sledge with such velocity over the yielding snow-fields as the camel would be to perform his long marches through the desert without the broad elastic sole-pad on which he firmly paces the unstable sands.
The short legs and broad feet of the reindeer likewise enable it to swim with greater ease—a power of no small importance in countries abounding in rivers and lakes, and where the scarcity of food renders perpetual migrations necessary. When the reindeer walks or merely moves, a remarkable clattering sound is heard to some distance, about the cause of which naturalists and travellers by no means agree. Most probably it results from the great length of the two digits of the cloven hoof, which when the animal sets its foot upon the ground separate widely, and when it again raises its hoof suddenly clap against each other.
A long mane of a dirty white color hangs from the neck of the reindeer. In summer the body is brown above and white beneath; in winter, long-haired and white. Its antlers are very different from those of the stag, having broad palmated summits, and branching back to the length of three or four feet. Their weight is frequently very considerable—twenty or twenty-five pounds; and it is remarkable that both sexes have horns, while in all other members of the deer race the males alone are in possession of this ornament or weapon.
