The long series of interesting voyages which have been made to the Arctic regions during the present century were commenced in 1818, after a considerable period of inaction and apathy had existed in regard to northern exploration. The renewal of these attempts was not brought about by accident or caprice, but was due to a great change, which had been noted by many whalers and navigators. Sir John Barrow, one of the most consistent and persistent advocates of Arctic exploration, as well as one of the most intelligent writers of his day, says: “The event alluded to was the disappearance of the whole, or greater part, of the vast barrier of ice which for a long period of time—perhaps for centuries—was supposed to have maintained its firm-rooted position on the eastern coast of Old Greenland, and its reappearance in a more southerly latitude, where it was met with, as was attested by various persons worthy of credit, in the years 1815, 1816, and 1817, by ships coming from the East Indies and America, by others going to Halifax and Newfoundland, and in different parts of the Atlantic, as far down as the 40th parallel of latitude.” Large islands of ice had impeded some voyagers for days together; icebergs miles in extent, and from one to two hundred feet high, had been reported. A vessel had been beset for eleven days on the coast of Labrador in floes of ice mixed with icebergs, many of which had huge rocks, gravel, soil, and wood upon them. In short, there was so much testimony from various sources to the vast break-up which had occurred that it created a great deal of attention among scientific men and navigators. It was perfectly understood whence the larger part of this ice must be derived. Scoresby the younger, in a letter to Sir Joseph Banks, recorded the fact that some 18,000 square miles of the surface of the Greenland seas included between the parallels of 74° and 80° were known to be void of ice, and that this immense change had been effected within two years. Intelligence received at Copenhagen in 1816 from Iceland indicated that the ice had broken loose from the opposite coast of Greenland, and floated away to the southward, after surrounding the shores of Iceland and filling all the creeks and bays of that island. This was repeated in 1817. [Illustration: SIR JOHN ROSS.] The public notice taken of the above facts led to two expeditions being ordered, the first of which, under Commander (afterwards Sir) John Ross, was remarkable for the number of officers who accompanied it, and who, later, acquired distinction in the Arctic explorations of this century. Parry, J. C. Ross (the commander’s nephew), Sabine (long President of the Royal Society, and a most distinguished _savan_), then a captain of the Royal Artillery, Hoppner, and others, were among the number. The ships employed were the _Isabella_ and _Alexander_, and the commander’s instructions were to attempt the north-west passage by the western route.
