to support this theory. Hasn't our learned Doctor any to tell us?" he added, half ironically.
"Oh, yes!" said Clawbonny, with a good-humored air of complacency, "I could tell you this, which may interest you, that whales which have been wounded in Davis's Straits have been captured subsequently on the coast of Tartary with the European harpoon still sticking in their sides."
"And since they have neither doubled Cape Horn nor the Cape of Good Hope, they must have got round North America. That is proof positive, Doctor."
"If you're not convinced yet, my good Shandon, I can bring forward other facts, such as the drift-wood which so abounds in Davis's Straits—larches, and aspens, and tropical substances. Now, we know that this South current would prevent this drift-wood from entering; if it comes out there, it must have got in by Behring's Straits, for there is no other way."
"I am quite satisfied, Doctor; one couldn't be long incredulous with you."
"Look out!" exclaimed Johnson; "here comes something quite à propos to our conversation. I see a jolly-sized log of wood floating there, and I propose we fish it up, with our chief officer's leave, and ask what country it comes from."
Shandon agreed, and soon after the log was hauled up on board, though with considerable difficulty. It was a trunk of mahogany, worm-eaten to the very center, which accounted for its floating.
"Here's a triumphant proof," exclaimed the Doctor, enthusiastically. "Since it cannot have been carried into Davis's Straits by the Atlantic currents, and since it cannot have been driven into the Polar basin by any of the North American rivers, seeing that it grew just below the Equator, it is evident it comes in a direct line from Behring's Straits. Besides, look at the worms. They belong to a species peculiar to the tropics. Listen, I'll tell you the whole history of this log. It was carried into the Pacific Ocean by some river, from the Isthmus of Panama or Guatemala. From thence it was borne along by the current into Behring's Straits, and driven out into the Polar Sea. I should assign rather a recent date to its departure, for it is neither old
