[Illustration: BEAKER SPONGES. From the sea off the mouth of the Kolyma. ] [Illustration: LIGHTHOUSE ISLAND. After a drawing by O. Nordquist. ] The Bear Islands lying off the mouth of the Kolyma are, for the most part, formed of a plutonic rock, whose upper part has weathered away, leaving gigantic isolated pillars. Four such pillars have given to the easternmost of the islands the name Lighthouse Island (Fyrpelaroen). Similar ruin-like formations are found not only on Cape Baranov, which lies right opposite, but also at a great number of other places in that portion of the north coast of Siberia which lies farther to the east. Generally these cliff-ruins are collected together over considerable areas in groups or regular rows. They have thus, when seen from the sea, so bewildering a resemblance to the ruins of a gigantic city which had once been surrounded by strong walls and been full of temples and splendid buildings, that one is almost tempted to see in them memorials of the exploits of a Tamerlane or a Chingis Khan, up here in the high north. The north side of the hill-tops was powdered with new-fallen snow, but the rest of the land was clear of snow. The distance between the south point of Ljachoff's Island and the Bear Islands is 360'. This distance we had traversed in three days, having thus made 120' in the twenty-four hours, or 5' per hour. If we consider the time lost in dredging, sounding, and determining the temperature and salinity of the water, and the caution which the navigator must observe during a voyage in quite unknown waters, this speed shows that during this part of our voyage we were hindered by ice only to a slight extent. Cape Baranov was passed on the night before the 5th September, the mouth of Chaun Bay on the night before the 6th September, and Cape Chelagskoj was reached on the 6th at 4 o'clock P.M. The distance in a right line between this headland and the Bear Islands is 180'. In consequence of the many _detours_ in the ice we had required 2-1/2 days to traverse this distance, which corresponds to 72' per day, or 3' per hour, a speed which in a voyage in unknown, and for the most part ice-bestrewed waters, must yet be considered very satisfactory. But after this our progress began to be much slower. At midnight the sun was already 12 deg. to 13 degree below the horizon, and the nights were now so dark that at that time of day we were compelled to lie still anchored to some large ground-ice. A farther loss of time was caused by the dense fog which often prevailed by day, and which in the unknown shallow water next the land compelled Captain Palander to advance with extreme caution. The navigation along the north coast of Asia began to get somewhat monotonous. Even the most zealous Polar traveller may tire at last of mere ice, shallow water and fog; and mere fog, shallow water and ice.
