"No, sir. It's all chance work, this sailing to the north. We must search where we can. It's of no use to say we'll go here or there; we must go where the ice will let us." "Exactly; and take what walrus and seal we can on the way. Have you ever touched at Jan Mayen?" "No, and never could get near enough to the island for fog and ice." "But you've heard a good deal about the place?" "Yes; I've heard that it's a land of high mountains, and that there's a volcano at one end. Let's see, there's a kind of seal there, too, that is very abundant; but the place is rarely touched at, being famous for fogs, currents, and ice--all enemies to navigation." "Well, we will see if we cannot have better luck, and try to get there in fine weather," said Captain Marsham. "What do you say, doctor?" "That it will be a treat to land there. Besides, we may find our friends." The doctor walked forward, and Steve followed, with the idea of landing upon an unexplored coast growing in its fascination; and as the naturalist leaned over the bows to peer down into the clear water, the lad edged up alongside. "Hullo, Steve! what are you thinking about?" saluted him. "Volcanoes." "Warm subject. Well, what about them?" "I was wondering why it was that these burning mountains are always found up in very cold regions among the ice and snow." "But are they?" "Oh yes," said Steve confidently. "There's Hecla in Iceland, and this one Mr Lowe talked about, and Captain Marsham says he saw a tremendous one amongst the ice toward the South Pole." "Indeed!" said the doctor sarcastically. "That makes three. What about the scores of others dotted about the earth in the hottest countries? Your theory will not hold water, my lad. But what's that man going aloft for? We can't be anywhere near land." This remark was occasioned by one of the men climbing the shrouds of the main-mast, making his way to the top, and then, as they watched him, climbing higher to the main topgallant crosstrees, where he stopped for some little time making an examination before descending. "Gone up to see if the ropes are safe," said Steve at last. But this soon proved to be a very lame conclusion, for the other three Norsemen and a sour-looking Scotchman, with a little brown mark at the corner of one lip, were busy getting something up out of the hold. The something resolved itself into a big tub about five feet in height, and narrow, while it was made higher by an iron framework or ring rising another six inches above the open top, and held projecting like a rail by means of stout bars attached to a hoop.
