These facts were very curious, and they increased Wrangell's desire to penetrate to the unknown northern districts; but the truth of all the rumours was not verified until our own day.

Between 1820 and 1824 Wrangell made four expeditions in sledges from the mouth of the Kolyma, which he made his headquarters, first exploring the coast to Cape Tchelagskoi, and enduring thirty-five degrees of cold; and in his second trip trying how far he could go across the ice, an experiment resulting in a journey of 400 miles from the land. In the third year (1822), Wrangell started in March with a view to verifying the report of a native who said he had seen land in the offing. He now came to an icefield, on which he advanced safely for a long distance, when it began to be less compact and was soon not solid enough to bear many sledges, so two small ones were selected, on which were packed a wherry, some planks, and some tools. The explorer then ventured on some melting ice which broke under his feet.

"Two small sledges were selected."

"At the outset," says Wrangell, "I had to make way for seven wersts across a bed of brine; further on appeared a surface furrowed with great crevasses, which we could only succeed in clearing by the help of our planks. I noticed in this part several small mounds of ice in such a liquefying condition that the slightest touch would suffice to break it and convert the mound into a round slough. The ice upon which we were travelling was without consistency, was but a foot in thickness, and—what was more—was riddled with holes.... I could only compare the appearance of the sea, at this stage, to an immense morass; and indeed the muddy water which issued from these thousands of crevasses, opening up in every direction, the melting snow mixed with earth and sand, those little mounds whence numerous streamlets were issuing,—all these combined to make the illusion perfect."

Wrangell had advanced some 140 miles, and it was the open sea or the polynia—as he calls vast expanses of water—north of Siberia, the outskirts of which he had reached, the same in fact as that already sighted by Leontjew in 1764, and Hedenstroem in 1810.

On his fourth voyage Wrangell and his small party of followers started from Cape Yakan, the nearest point to the Arctic regions, and, after passing Cape Tchelagskoi, made for the north; but a violent storm broke up the ice, there only three feet thick, and involved the explorers in the greatest danger. Now dragged across some large unbroken slab, now wet to the waist on a moving plank, sometimes above and sometimes under water, or moored to a block serving as a ferryboat, which the swimming dogs dragged along, they at last succeeded in crossing the shifting reverberating ice and regaining the land, owing their life to the strength and agility of their teams of dogs alone. Thus closed the last attempt made to reach the districts north of Siberia.

The Arctic calotte1 was meanwhile being attacked from the other side with equal energy and yet more perseverance. It will be remembered with what untiring enthusiasm the famous north-west passage had been sought. No sooner had the peace of 1815 necessitated the disarmament of numerous English vessels and set free their officers on half-pay, than the Admiralty, unwilling to let experienced seamen rust in idleness, sought for them some employment. It was under these circumstances that the search for the north-west passage was resumed.

The Alexander, 252 tons, and the Isabel, 385, under command of the experienced officers, John Ross and Lieutenant Parry, with James Ross, Back, and Belcher, who were to win honour in Arctic explorations amongst their subordinates, were sent by the Government to explore Baffin's Bay and set sail on the 18th April. After touching at the Shetland Islands, and seeking in vain for the submerged land seen by Bass in N. lat. 57° 28', the explorers came on the 26th May to the first ice, and on the 2nd June surveyed the western coast of Greenland, hitherto very imperfectly laid down in maps, finding it greatly encumbered by ice. Indeed the governor of the Dutch settlement of Whale Island told them that the severity of the winter months had been steadily increasing during the eleven years of his residence in the country.
