It is not that the Arctic night makes a heavy demand on our physical faculties. Against its rigour man is able to defend himself; but it is less easy to provide against its strain on the moral and intellectual faculties. The darkness which clothes Nature for so long a period reveals to the senses of the European explorer what is virtually a new world, and the senses do not well adapt themselves to that world. The cheering influences of the rising sun, which invite to labour; the soothing influences of the evening twilight, which beguile to rest; that quick change from day to night, and night to day, which so lightens the burden of existence in our temperate clime to mind and soul and body, kindling the hope and renewing the courage,--all these are wanting in the Polar world, and man suffers and languishes accordingly. The grandeur of Nature, says Dr. Hayes, ceases to give delight to the dulled sympathies, and the heart longs continually for new associations, new hopes, new objects, new sources of interest and pleasure. The solitude is so dark and drear as to oppress the understanding; the imagination is haunted by the desolation which everywhere prevails; and the silence is so absolute as to become a terror. The lover of Nature will, of course, find much that is attractive in the Arctic night; in the mysterious coruscations of the aurora, in the flow of the moonlight over the hills and icebergs, in the keen clearness of the starlight, in the sublimity of the mountains and the glaciers, in the awful wildness of the storms; but it must be owned that they speak a language which is rough, rugged, and severe. All things seem built up on a colossal scale in the Arctic world. Colossal are those dark and tempest-beaten cliffs which oppose their grim rampart to the ceaseless roll and rush of the ice-clad waters. Colossal are those mountain-peaks which raise their crests, white with unnumbered winters, into the very heavens. Colossal are those huge ice-rivers, those glaciers, which, born long ago in the depths of the far-off valleys, have gradually moved their ponderous masses down to the ocean’s brink. Colossal are those floating islands of ice, which, outrivalling the puny architecture of man, his temples, palaces, and pyramids, drift away into the wide waste of waters, as if abandoned by the Hand that called them into existence. Colossal is that vast sheet of frozen, frosty snow, shimmering with a crystalline lustre, which covers the icy plains for countless leagues, and stretches away, perhaps, to the very border of the sea that is supposed to encircle the unattained Pole.
