At one period--and not a very distant one either--savans, and, amongst others, the French philosopher St. Pierre, believed icebergs to be the accumulated snow and ice of ages, which, forming at the poles, detached themselves from the parent mass: this, as they then thought, had no reference to the existence of land or water. Such an hypothesis for some time gave rise to ingenious and startling theories as to the effect which an incessant accumulation of ice would have on the globe itself; and St. Pierre hinted at the possibility of the huge cupolas of ice, which, as he believed, towered aloft in the cold heavens of the poles, suddenly launching towards the equator, melting, and bringing about a second deluge. Had the immortal Cook been aware of the certainty of land being close to him, when, in the Antarctic regions, he found himself amongst no less than one hundred and eighty-six icebergs in December, 1773; he who, from the deck of a collier, had risen to be the Columbus of England, might have then plucked the laurel which Sir James Ross so gallantly won in the discovery of the circumpolar continent of Queen Victoria's Land. On every side of the southern pole, on every meridian of the great South Sea, the seaman meets icebergs. Not so in the north. In the 360 degrees of longitude, which intersects the parallel of 70 degrees north (about which parallel the coasts of America, Europe, and Asia will be found to lie), icebergs are only found over an extent of some 55 degrees of longitude, and this is immediately in and about Greenland and Baffin's Bay. In fact, for 1375 miles of longitude we have icebergs, and then for 7635 geographical miles none are met with. This interesting fact is, in my opinion, most cheering, and points strongly to the possibility that no extensive land exists about our northern pole,--a supposition which is borne out by the fact, that the vast ice-fields off Spitzbergen show no symptoms of ever having been in contact with land or gravel. Of course, the more firmly we can bring ourselves to believe in the existence of an ocean road leading to Behring's Straits, the better heart we shall feel in searching the various tortuous channels and different islands with which, doubtless, Franklin's route has been beset. It was not, therefore, without deep interest that I passed the boundary which Nature had set in the west to the existence of icebergs, and endeavoured to form a correct idea of the cause of such a phenomenon.
