“The parent of light and life everywhere,” says Dr. Hayes, “he is the same within these solitudes. The germ awaits him here as in the Orient; but there it rests only through the short hours of a summer night, while here it reposes for months under a sheet of snows. But after a while the bright sun will tear this sheet asunder, and will tumble it in gushing fountains to the sea, and will kiss the cold earth, and give it warmth and life; and the flowers will bud and bloom, and will turn their tiny faces smilingly and gratefully up to him, as he wanders over these ancient hills in the long summer. The very glaciers will weep tears of joy at his coming. The ice will loose its iron grip upon the waters, and will let the wild waves play in freedom. The reindeer will skip gleefully over the mountains to welcome his return, and will look longingly to him for the green pastures. The sea-fowls, knowing that he will give them a resting-place for their feet on the rocky islands, will come to seek the moss-beds which he spreads for their nests; and the sparrows will come on his life-giving rays, and will sing their love-songs through the endless day.” With the sun return the Arctic birds, and before we quit the realm of waters we propose to glance at a few of those which frequent the cliffs and shores during the brief Polar summer. Among the first-comers is the dove-kie or black guillemot (_Uria grylle_), which migrates to the temperate climates on the approach of winter, visiting Labrador, Norway, Scotland, and even descending as far south as Yorkshire. In fact, we know of no better place where to observe its habits than along the immense range of perpendicular cliffs stretching from Flamborough Head to Filey Bay. Here, on the bare ledges of this colossal ocean-wall, the guillemot lays its eggs, but without the protection of a nest; some of them parallel with the edge of the shelf, others nearly so, and others with their blunt and sharp ends indiscriminately pointing to the sea. They are not affixed to the rock by any glutinous matter, or any foreign substance whatever. You may see as many as nine or ten, or sometimes twelve, old guillemots in a line, so near to each other that their wings almost touch. The eggs vary greatly in size and shape and colour. Some are large, others small; some exceedingly sharp at one end, others rotund and globular. It is said that, if undisturbed, the guillemot never lays more than one egg; but if that be taken away, she will lay another, and so on. But Audubon asserts that he has seen these birds sitting on as many as three eggs at a time. [Illustration: SEA-BIRDS IN THE POLAR REGIONS.]
