The thaw began about the middle of May, and towards the close of the month the sledge-parties were forced to wade through the water which flooded the surface of the sea-ice. In June, large portions of land-ice were continually breaking off, and much open water could be descried in the south-east. But it was not until the 10th of July that the ice around the ship broke up. Four days later, boating became practicable, and a voyage was made to the Eskimo village on Clavering Island. It ended in disappointment,--the village having been deserted, and the huts having fallen into ruin. On the 22nd of July, the _Germania_ once more steamed to the northward, to renew the attempt of the preceding year. Her boiler-tubes, however, leaked so seriously, that it was evident the boiler would speedily fail altogether. After some delay it was temporarily patched up; and by following a narrow channel between the loose pack-ice and the firm ice-belt of the coast, she contrived to push forward to the north-east cape of Shannon Island, in lat. 75° 29’ N. Here the ice barrier showed itself compact, solid, and insuperable. The _Germania_, therefore, on the 30th of July, made for the southward, and continued her explorations in that direction. The “Mackenzie Inlet,” which Captain Clavering discovered in 1823, was found to have disappeared; its place being occupied by a low, flat plain, on which herds of reindeer were pasturing. So unaccustomed were they to the sight of man, and so fearless of danger, that five of them were speedily shot. On the 6th of August, the _Germania_ discovered and entered a broad, deep fiord in lat. 73° 13’. It was perfectly free from ice; but a fleet of huge icebergs was sailing out of it with the current. It was soon noticed that the farther they ascended this picturesque sea-arm, the warmer became the temperature of the air and of the surface water. It threw off several branches, and these wound in and out among lofty mountains. Their declivities were washed by cascades, and their ravines filled with glaciers; so that the prospect thus unexpectedly opened up of the interior of Greenland was singularly romantic and impressive. Some of the adventurers ascended a mountain 7000 feet in height; but even from this lofty watch-tower no limit could be discerned to the western or principal arm of the fiord. In about 32° W. long. the mountain-range rose, it was ascertained, to an elevation of 14,000 feet. The _Germania_ penetrated for seventy-two miles into this remarkable inlet, and reached 26° W. long.; but her boiler acting irregularly, and Captain Koldewey being apprehensive of the consequences if it wholly failed, commenced his homeward voyage on the 17th of August. He re-entered the pack-ice at the mouth of the fiord, and was occupied until the 24th in forcing his way through it,--reaching the open, iceless sea in lat. 72° N. and long. 14° W.
