Along with the rotge we find among the ice far out at sea flocks of alkor (looms, or Brünnich's guillemots), and the nearer we come to the coast, the more do these increase in number, especially if the cliffs along the shore offer to this species of sea-fowl—the most common of the Polar lands—convenient hatching places. For this purpose are chosen the faces of cliffs which rise perpendicularly out of the sea, but yet by ledges and uneven places afford room for the hatching fowl. On the guillemot-fells proper, eggs lie beside eggs in close rows from the crown of the cliff to near the sea level, and the whole fell is also closely covered with seafowl, which besides in flocks of thousands and thousands fly to and from the cliffs, filling the air with their exceedingly unpleasant scream. The eggs are laid, without trace of a nest, on the rock, which is either bare or only covered with old birds' dung, so closely packed together, that in 1858 from a ledge of small extent, which I reached by means of a rope from the top of the fell, I collected more than half a barrel-full of eggs. Each bird has but one very large egg, grey pricked with brown, of very variable size and form. After it has been sat upon for some time, it is covered with a thick layer of birds' dung, and in this way the hunters are accustomed to distinguish uneatable eggs from fresh.
If a shot be fired at a "loomery," the fowl fly away in thousands from their hatching places, without the number of those that are not frightened away being apparently diminished. The clumsy and short-winged birds, when they cast themselves out of their places, fall down at first a good way before they get "sufficient air" under their wings to be able to fly. Before this takes place, many plump down into the water, sometimes even into the boat which may be rowed along the foot of the fell.
An unceasing, unpleasant cackling noise indicates that a continual gossip goes on in the "loomery"; and that the unanimity there is not great, is proved by the passionate screams which are heard now and then. A bird squeezes forward in order to get a place on a ledge of rock already packed full, a couple of others quarrel about the ownership of an egg which has been laid on a corner of the rock only a few inches broad, and which now during the dispute is precipitated into the abyss. By the beginning of July most of the eggs are uneatable. I have seen the young of the size of a rotge accompany their mothers in the middle of August. The loom breeds on Walden Island and the north coast of North-East land, accordingly far north of 80°. I found the largest "loomeries" on Spitzbergen south of Lomme Bay in Hinloopen Strait, at the southern entrance to Van Meyen Bay in Bell Sound, and at Alkornet in Ice Fjord. In respect to the large number of fowl, however, only the first of these can compete with the south shore of Besimannaja Bay (72° 54' N.L.) and with the part of Novaya Zemlya that lies immediately to the south of this bay. The eggs of the loom are palatable, and the flesh is excellent, though not quite free from the flavour of train oil. In any case it tastes much better than that of the eider.
Along with the rotge and the loom two nearly allied species of birds, lunnefogeln, the Arctic puffin (Mormon arcticus, L.) and tejsten or tobis-grisslan, the black guillemot (Uria grylle, L.) are to be seen among the drift-ice. I do not know any puffin-fells on Spitzbergen. The bird appears to breed there only in small numbers, though it is still found on the most northerly part of the island. On Novaya Zemlya, too, it occurs rather sparingly. The black guillemot, on the other hand, is found everywhere, though never collected in large flocks, along the shores of Spitzbergen, and Novaya Zemlya, even as far north as Parry Island in 80° 40' N.L., where in 1861 I saw several of their nests. These are placed near the summits of steep cliffs along the shore. The black guillemots often swim out together in pairs in the fjords. Their flesh has about the same taste as Brünnich's guillemot, but is tougher and of inferior quality; the eggs, on the other hand, are excellent.
The sea fowl mentioned above are never met with inland. They never settle on a grassy sward or on a level sandy beach. The steep fowl-fell sides, the sea, ground-ice, pieces of drift-ice and small stones rising above the water, form their habitat. They swim with great skill both on, and under the water. The black guillemots and rotges fly swiftly and well; Brünnich's guillemots, on the contrary, heavily and ill. The latter therefore do not perhaps remove in winter farther from their hatching places than to the nearest open water, and it is probable that colonies of Brünnich's guillemots are not located at places where the sea freezes completely even far out from the coast. On this perhaps depends the scarcity of Brünnich's guillemot in the Kara Sea.
While sailing in the Arctic Ocean, vessels are nearly always attended by two kinds of gulls, the greedy stormaosen or borgmaesteren, glaucous gull (Larus glaucus, Brünn.), and the gracefully formed, swiftly flying kryckian or tretaoiga maosen, kittiwake (Larus tridactylus, L.), and if the hunter lies to at an ice-floe to flense upon it a seal which has been shot, it is not long till a large number of snow-white birds with dark blue bills and black legs settle down in the neighbourhood in order that they may get a portion of the spoil. They belong to the third kind of gull common in the north, ismaosen, the ivory gull (Larus eburneus, Gmel.).
