East of the Bear Islands heavy sea-ice in pretty compact masses had drifted down towards the coast, but still left an open ice-free channel along the land. Here the higher animal world was exceedingly poor, which, as far as the avi-fauna was concerned, must be in some degree ascribed to the late season of the year. For Wrangel mentions a cliff at the Bear Islands which was covered with numberless birds' nests. He saw besides, on the largest of these islands, traces of the bear, wolf, fox, lemming, and reindeer (Wrangel's _Reise_, i. pp. 304 and 327). Now the surrounding sea was completely deserted. No Polar bear saluted us from the ice-floes, no walruses, and only very few seals were visible. During many watches not a single natatory bird was seen. Only the phalarope was still met with in large numbers, even pretty far out at sea. Perhaps it was then migrating from the north. The lower animal world was more abundant. From the surface of the sea the drag-net brought up various small surface crustacea, inconsiderable in themselves, but important as food for larger animals; and from the sea-bottom were obtained a large number of the same animal forms as from the sound at Svjatoinos, and in addition some beautiful asterids and a multitude of very large beaker sponges. On the 3rd September, after we had sailed past the Bear Islands, the course was shaped right for Cape Chelagskoj. This course, as will be seen by a glance at the map, carried us far from the coast, and thus out of the channel next the land, in which we had hitherto sailed. The ice was heavy and close, although at first so distributed that it was navigable. But with a north wind, which began to blow on the night before the 1st September, the temperature fell below the freezing-point, and the water between the pieces of drift-ice was covered with a very thick crust of ice, and the drift-ice came closer and closer together. It thus became impossible to continue the course which we had taken. We therefore turned towards the land, and at 6 o'clock P.M., after various bends in the ice and a few concussions against the pieces of ice that barred our way, again reached the ice-free channel, eight to twelve kilometres broad, next the land. While we lay a little way in among the drift-ice fields we could see no sign of open water, but it appeared as if the compact ice extended all the way to land, a circumstance which shows how careful the navigator ought to be in expressing an opinion as to the nature of the _pack_ beyond the immediate neighbourhood of the vessel. The temperature of the air, which in the ice-field had sunk to -3 deg., now rose at once to + 4.1 deg., while that of the water rose from -1 deg..2 to +3.5 deg., and its salinity fell from 2.4 to 13 per cent. All showed that we had now come into the current of the Kolyma, which from causes which have been already stated, runs from the mouth of the river along the land in an easterly direction.
