When everything had been said and re-said over and over again, Glenarvan informed Harry Grant about Ayrton. Grant confirmed the quartermaster's confession as far as his disembarkation on the coast of Australia was concerned.

"He is an intelligent, intrepid man," he added, "whose passions have led him astray. May reflection and repentance bring him to a better mind!"

But before Ayrton was transferred, Harry Grant wished to do the honors of his rock to his friends. He invited them to visit his wooden house, and dine with him in Robinson Crusoe fashion.

Glenarvan and his friends accepted the invitation most willingly. Robert and Mary were eagerly longing to see the solitary house where their father had so often wept at the thought of them. A boat was manned, and the Captain and his two children, Lord and Lady Glenarvan, the Major, John Mangles, and Paganel, landed on the shores of the island.

A few hours sufficed to explore the whole domain of Harry Grant. It was in fact the summit of a submarine mountain, a plateau composed of basaltic rocks and volcanic DEBRIS. During the geological epochs of the earth, this mountain had gradually emerged from the depths of the Pacific, through the action of the subterranean fires, but for ages back the volcano had been a peaceful mountain, and the filled-up crater, an island rising out of the liquid plain. Then soil formed. The vegetable kingdom took possession of this new land. Several whalers landed domestic animals there in passing; goats and pigs, which multiplied and ran wild, and the three kingdoms of nature were now displayed on this island, sunk in mid ocean.
