"This man was called Ayrton. He was, in fact, the boatswain's mate of the _Britannia_, as his papers showed. But, separated from Captain Grant at the moment when the ship struck upon the rocks, he had till then believed that the captain with all his crew had perished, and that he, Ayrton, was the sole survivor of the _Britannia_. "'Only,' added he, 'it was not on the west coast, but on the east coast of Australia that the vessel was lost; and if Captain Grant is still living, as his document indicates, he is a prisoner among the natives, and it is on the other coast that he must be looked for.' "This man spoke in a frank voice and with a confident look; his words could not be doubted. The Irishman, in whose service he had been for more than a year, answered for his trustworthiness. Lord Glenarvan, therefore, believed in the fidelity of this man, and, by his advice, resolved to cross Australia, following the thirty-seventh parallel. Lord Glenarvan, his wife, the two children, the major, the Frenchman, Captain Mangles, and a few sailors composed the little band under the command of Ayrton, whilst the _Duncan_, under charge of the mate, Tom Austin, proceeded to Melbourne, there to await Lord Glenarvan's instructions. "They set out on the 23rd of December, 1854. "It is time to say that Ayrton was a traitor. He was, indeed, the boatswain's mate of the _Britannia_; but, after some dispute with his captain, he had endeavoured to incite the crew to mutiny and seize the ship, and Captain Grant had landed him, on the 8th of April, 1852, on the west coast of Australia, and then sailed, leaving him there, as was only just. "Therefore this wretched man knew nothing of the wreck of the _Britannia_; he had just heard of it from Glenarvan's account. Since his abandonment, he had become, under the name of Ben Joyce, the leader of the escaped convicts; and if he boldly maintained that the wreck had taken place on the east coast, and led Lord Glenarvan to proceed in that direction, it was that he hoped to separate him from his ship, seize the _Duncan_, and make the yacht a pirate in the Pacific." Here the stranger stopped for a moment. His voice trembled, but he continued,-- "The expedition set out and proceeded across Australia. It was inevitably unfortunate, since Ayrton, or Ben Joyce, as he may be called, guided it, sometimes preceded, sometimes followed by his band of convicts, who had been told what they had to do.
