every mile I advanced I found the atmosphere growing warmer, and the Northern Lights brighter and brighter. There could be no doubt about it; those lights were the cause of the unexpected warmth I encountered; so warm, indeed, did the air become, that I am certain many a man would have turned back for fear of being roasted alive, but I was not to be daunted. Onward I went till I got within less than a mile of one of the biggest fires I ever saw. The effect was grand and beautiful in the extreme. You might suppose yourself looking at a city fifty times as large as London, and every house in it as big as Saint Paul's, and every part of it blazing away at the same time, and even then you would have no conception of the magnificence of the scene which met my view, as I beheld the source of those far-famed Northern Lights, the Aurora Borealis, as the learned people call them. "The flames, you must know, were not of that bright hot colour which issue from a furnace, but were of a delicate pale red, flickering and playing about in the most curious way imaginable, sometimes blazing up to the height of a mile or so, and then sinking down to a few hundred feet. The heat at the distance I was then from it was rather pleasant than oppressive; it had not even melted the snow on the ground, but of course that was so hard frozen, that it would have required a very warm fire to have made any impression on it. Well, as I advanced I began to lick my chops at the thoughts of the hot dinner I intended to enjoy-- for, after all, however philosophical a man may be, his appetite, if he is hungry, must be satisfied before he is fit for anything--when I beheld a number of moving objects, scarcely distinguishable from the snow, encircling the fire. I could not make out at first what they were, but on approaching still nearer, I discovered the truth, though I could scarcely believe my eyes, for there, sitting up on their hams, were countless thousands of polar bears, warming their paws before the aurora borealis. It is a fact as true as anything I have been telling you, and at once fully accounted to my mind for the disappearance of bears from the arctic regions during the winter months, and fully refutes the popular idea, that they sit moping by themselves in caverns, employing their time in sucking their paws. "Not liking the idea of losing my hot dinner, not to speak of the disappointment of not being able to say that I had been chock up to the North Pole, I determined to venture among them." "It wouldn't give you much concern to say you had been there, at all events, even if you hadn't," growled out a voice from one of the hammocks. "Sir!" exclaimed the boatswain very sternly, "I would have you to know that I scorn to exaggerate the truth, or to make an assertion which is not in strict accordance with the facts. If you doubt my words, stop your ears or go to sleep, or I'll shut up altogether."
