“Yes, indeed, dear child,” M. Zermatt replied. “As soon as we saw the canoes making for Deliverance Bay, we took refuge on Shark’s Island, thinking that we might be able to defend ourselves here against an attack by them.”

“Papa,” said Frank, “the savages know now that you are on this island.”

“Yes, they do,” M. Zermatt answered, “but thank God, they have not succeeded in landing here yet, and our old flag is still flying!”

The following is a very brief summary of what had happened since the time at which the first part of this narrative ended.

On the return of the dry season, after the expeditions which resulted in the discovery of the Montrose River, a reconnaissance was carried out as far as the range of mountains, where Mr. Wolston, Ernest and Jack planted the British flag on the summit of Jean Zermatt peak. That happened some ten or twelve days before the boat arrived on the southern coast of the island, and if the expedition had been carried beyond the range they might have met Captain Gould at Turtle Bay. But Mr. Wolston and the two brothers had not ventured across the desert plateau.

The newcomers were told how Jack, carried away by his wild desire to capture a young elephant, had fallen into the midst of savages, who made him prisoner. After escaping from them, he had brought back the grave news of their presence on the island.

Thoroughly alarmed, the Zermatts and Wolstons made plans in anticipation of an attack upon Rock Castle, and maintained a watch day and night.

For three months, however, nothing happened. The savages did not appear. It seemed that they had finally left the island.

But there was matter of new anxiety in the fact that the Unicorn, due to arrive in September or October, made no appearance off New Switzerland. In vain did Jack go many times to the top of Prospect Hill to look out for the return of the corvette. On each occasion he had to come back to Rock Castle without having seen her.

It should be mentioned here that the ship observed by Mr. Wolston, Ernest, and Jack from the summit of Jean Zermatt peak was no other than the Flag, as could be proved by comparison of dates. Yes, it was the three-master which had fallen into the hands of Robert Borupt. After approaching the island, she had sailed to the Pacific Ocean, through the Sunda Seas, never to be heard of again.
