"You see," he continued, addressing himself to the others, "Desolation Island is in 50 degrees south latitude and 70 degrees east longitude. As I make out, More's course led him over about ten degrees of longitude in a southwest course. That course depended altogether upon the ocean currents. Now there is a great antarctic drift-current, which flows round the Cape of Good Hope and divides there, one half flowing past the east coast of Africa and the other setting across the Indian Ocean. Then it unites with a current which flows round the south of Van Dieman's Land, which also divides, and the southernmost current is supposed to cross the Pacific until it strikes Cape Horn, around which it flows, dividing as before. Now my theory is, that south of Desolation Island--I don't know how far--there is a great current setting toward the South Pole, and running southwest through degrees of longitude 60, 50, 40, 30, 20, 10, east of Greenwich; and finally sweeping on, it would reach More's volcanoes at a point which I should judge to be about 80 degrees south latitude and 10 degrees west longitude. There it passes between the volcanoes and bursts through the vast mountain barrier by a subterranean way, which has been formed for it in past ages by some primeval convulsion of nature. After this it probably sweeps around the great South Polar ocean, and emerges at the opposite side, not far from the volcanoes Erebus and Terror." Here the doctor paused, and looked around with some self-complacency. "Oh," said Melick, "if you take that tone, you have us all at your mercy. I know no more about the geography of the antarctic circle than I do of the moon. I simply criticize from a literary point of view, and I don't like his underground cavern with the stream running through it. It sounds like one of the voyages of Sinbad the Sailor. Nor do I like his description; he evidently is writing for effect. Besides, his style is vicious; it is too stilted. Finally, he has recourse to the stale device of a sea-serpent." "A sea-serpent!" repeated the doctor. "Well, for my part I feel by no means inclined to sneer at a sea-serpent. Its existence cannot be proved, yet it cannot be pooh-poohed. Every schoolboy knows that the waters of the sea were once filled with monsters more tremendous than the greatest sea-serpent that has ever been imagined. The plesiosaurus, with its snakelike head, if it existed now, would be called a sea-serpent. Some of these so-called fossil animals may have their representatives still living in the remoter parts of the world. Think of the recently discovered ornithorhynchus of Australia!" "If you please, I'd really much rather not," said Melick with a gesture of despair. "I haven't the honor of the gentleman's acquaintance." "Well, what do you think of his notice of the sun, and the long light, and his low position on the horizon?"
