When the navigator has gone a little further north and come to an ice-bestrewed sea, the swell ceases at once, the wind is hushed and the sea becomes bright as a mirror, rising and sinking with a slow gentle heaving. Flocks of little auks (_Mergulus alle_, L.) Bruennich's guillemots (_Uria Bruennichii_, Sabine), and black guillemots (_Uria grylle_, L.) now swarm in the air and swim among the ice floes. The _alke-kung_ (little auk), also called the "sea king," or rotge, occurs only sparingly off the southern part of Novaya Zemlya, and does not, so far as I know, breed there. The situation of the land is too southerly, the accumulations of stones along the sides of the mountains too inconsiderable, for the thriving of this little bird. But on Spitzbergen it occurs in incredible numbers, and breeds in the talus, 100 to 200 metres high, which frost and weathering have formed at several places on the steep slopes of the coast mountain sides; for instance, at Horn Sound, at Magdalena Bay, on the Norways (near 80 deg. N.L.), and other places. These stone heaps form the palace of the rotge, richer in rooms and halls than any other in the wide round world. If one climbs up among the stones, he sees at intervals actual clouds of fowl suddenly emerge from the ground either to swarm round in the air or else to fly out to sea, and at the same time those that remain make their presence underground known by an unceasing cackling and din, resembling, according to Friedrich Martens, the noise of a crowd of quarrelling women. Should this sound be stilled for a few moments, one need only attempt in some opening among the stones to imitate their cry (according to Martens: _rott-tet-tet-tet-tet_) to get immediately eager and sustained replies from all sides. The fowl circling in the air soon settle again on the stones of the mountain slopes, where, squabbling and fighting, they pack themselves so close together that from fifteen to thirty of them may be killed by a single shot. A portion of the flock now flies up again, others seek their safety like rats in concealment among the blocks of stone. But they soon creep out again, in order, as if by agreement, to fly out to sea and search for their food, which consists of crustacea and vermes. The rotge dives with ease. Its single blueish-white egg is laid on the bare ground without a nest, so deep down among the stones that it is only with difficulty that it can be got at. In the talus of the mountains north of Horn Sound I found on the 18th June, 1858, two eggs of this bird lying directly on the layer of ice between the stones. Probably the hatching season had not then begun. Where the main body of these flocks of birds passes the winter, is unknown,[62] but they return to the north early--sometimes too early. Thus in 1873 at the end of April I saw a large number of rotges frozen to death on the ice in the north part of Hinloopen Strait. When cooked the rotge tastes
