On the 20th of December, they arrived off Cape Bernouilli, which terminates Lacepede Bay, and yet not a vestige of the BRITANNIA had been discovered. Still this was not surprising, as it was two years since the occurrence of the catastrophe, and the sea might, and indeed must, have scattered and destroyed whatever fragments of the brig had remained. Besides, the natives who scent a wreck as the vultures do a dead body, would have pounced upon it and carried off the smaller DEBRIS. There was no doubt whatever Harry Grant and his companions had been made prisoners the moment the waves threw them on the shore, and been dragged away into the interior of the continent.

But if so, what becomes of Paganel's ingenious hypothesis about the document? viz., that it had been thrown into a river and carried by a current into the sea. That was a plausible enough theory in Patagonia, but not in the part of Australia intersected by the 37th parallel. Besides the Patagonian rivers, the Rio Colorado and the Rio Negro, flow into the sea along deserted solitudes, uninhabited and uninhabitable; while, on the contrary, the principal rivers of Australia--the Murray, the Yarrow, the Torrens, the Darling--all connected with each other, throw themselves into the ocean by well-frequented routes, and their mouths are ports of great activity. What likelihood, consequently, would there be that a fragile bottle would ever find its way along such busy thoroughfares right out into the Indian Ocean?
