Tyke had been enjoying himself hugely from the start. He had utterly cast aside all thoughts of the business he had left behind him, and when Drew sometimes referred to it he refused to listen. The sea air and the delight of being once more in the surroundings of his early days had proved a tonic. His leg mended with magical rapidity, and by the time they had been ten days at sea he cast aside his crutches and managed to get about with the aid of a cane. Almost every moment of the day and evening when he was not at meals, he spent on deck, exchanging yarns with Captain Hamilton, studying the set of the sails, or gazing on the boundless expanse of sea and sky.

The weather so far had been perfect, and the schooner had slipped along steadily and rapidly, most of the time carrying her full complement of canvas. The captain thought that in about two or three days more they would be in the vicinity of Martinique. Once there, to the westward of that island, they would cruise about until the cay shaped like the hump of a whale should appear on the horizon.

But despite the good weather, there had been for some time past a shadow on the face of the captain which betrayed uneasiness. The young people, absorbed in their own affairs, had not noticed it, but Tyke's shrewd eyes had seen that all was not well, and one day when the captain dropped into a chair beside him, he broached the subject without ceremony.

"What's troubling you, Cap'n Rufe?" he asked. "Out with it and git it off your chest."

"Oh, nothing special," replied the captain evasively.

"Yes there is," retorted Tyke. "You can't fool me. So let's have it."

"Well, to tell you the truth," said Captain Hamilton, "I don't quite like the actions of the crew."

"No more do I," said Tyke calmly.

"Have you noticed it too?"

"I've still got a pair of pretty good eyes in my head. But heave ahead."
