They had unmoored the pinnace, and were on their way to Shark's Island.

"You are about to announce to your sons their departure?" said Willis, inquiringly.

"Yes; but my heart almost fails me."

"The iron must be struck while it is hot. Will you commission me to whisper a few words in their ear?"

"Thanks, Willis; but what right have I to expect courage from them, if I exhibit weakness myself? No, my friend, I may shed tears in your presence, but not before them."

"A man ought never to allow his feelings to get the better of his courage," said Willis, in whose eyes, however, the dust was evidently playing sad havoc.

"These boys have almost never been absent from me. I have watched them grow up from infancy to adolescence, and from adolescence to manhood; they have always been dutiful and obedient, and with gratitude I have blessed them every night of their lives. But stern are the decrees of Fate; I must command them to depart from me—perhaps for ever!"

"There are evils that lead to good," said Willis, "even though these evils be the Straits of Magellan or the storms of the Indian Ocean."

Here the pinnace reached the offing of Shark's Island, where Fritz and Jack, leaning on the battery, watched the progress of the boat.

"Do you observe how downcast my father looks?" said Fritz.
