2. The belief of past times[11] in such a sea shows how unsatisfactory is the simple to man’s mind, and how old is his tendency to clothe the remote and the uncommon with a garment of the marvellous. What was the open Polar Sea but the “Harz Sea” of the North, or the legendary zone of the ever-sunny Eden of the Hyperboreans, far beyond the land of the Anthropophagi over which was spread an atmosphere veiled in snow, and through which no light could penetrate! Who has ever seen this open Polar Sea? Do the accounts of navigators confirm its existence? Nay—their accounts are rather a series of counter-statements: Hudson, Baffin, Phipps, Tschitschagoff, Buchan, Franklin, Parry, Collinson, Scoresby, M’Clintock, Koldewey, Torell, Nordenskjöld, have all expressed their disbelief in its existence. If some have pretended that they have seen it, how strange it is that they never sailed on it! It has recently been attempted to make the great champion of the Polar question, Dr. Petermann, a supporter of this conception; but in the “Mittheilungen” of this highly meritorious geographer, there are many passages which most emphatically protest against it. His views extend only to an inner Polar Sea navigable under certain circumstances, and every one acquainted with those regions may adopt his point of view, though he refuses to admit the existence of the open Polar Sea. 3. In those centuries when the Natural Sciences were little cultivated, when the theories of the Trade Winds, of Equatorial and Polar sea-currents, were still unknown, and when as yet the processes in the Frozen Ocean had not been submitted to scientific investigation, we cannot be surprised at the preconceptions which were formed concerning its phenomena. In those times all beyond Norway was a chaos of ice-filled darkness; the necessity of a scientific investigation of those wastes was not felt; and down to the time of Sir John Ross, Polar navigators on their return home brought with them no kind of scientific knowledge of Nature in the Arctic regions. To reach India was the main if not the only end they had in view. The instructions which Willoughby, the first Polar navigator, received, give us an insight into the delusions of earlier times. These, for example, warned adventurers against men-eaters who swam naked in the sea, and in the rivers. It was the period of fables long since forgotten. Maldonado, de Fuca, Bernarda, Yelmer, Andrejew, Martinière, and the whale-fishers, brought home tales of passages to India discovered, of new continents, of the ascertained connexion of Novaya Zemlya with the northernmost point of Siberia (Yelmerland) or even with Greenland. Two centuries ago the failure of all attempts at a North-East passage was attributed to Russia’s commercial policy, inasmuch as it had been proved to the satisfaction of all, that the heat was greater in the north, that the seas there ceased to freeze, and that the country was covered with a luxuriant green!
