"'A Scotchman like yourself, my lord,' replied the man; 'I am one of Captain Grant's crew—one of the castaways of the Britannia.'
"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.
"Meanwhile the Duncan had been sent to Melbourne for repairs. It was necessary, then, to get Lord Glenarvan to order her to leave Melbourne and go to the east coast of Australia, where it would be easy to seize her. After having led the expedition near enough to the coast, in the midst of vast forests with no resources, Ayrton obtained a letter, which he was charged to carry to the mate of the Duncan—a letter which ordered the yacht to repair immediately to the east coast, to Twofold Bay, that is to say, a few days' journey from the place where the expedition had stopped. It was there that Ayrton had agreed to meet his accomplices, and two days after gaining possession of the letter, he arrived at Melbourne.
