His spoken opinion is that such a journey is not merely difficult but impossible journey in a frail native canoe across one hundred and fifty miles of open and rough sea; although his private opinion is other than that.

"Admiral," says Mendez again, "you know very well that I have risked my life for you and the people before and would do it again.

But there are others who have at least as good a right to this great honour and peril as I have; let me beg of you, therefore, to summon all the company together, make this proposal to them, and see if any one will undertake it.

If not, I will once more risk my life." The proposal being duly made to the assembled crews, every one, as cunning Mendez had thought, declares it impossible; every one hangs back.
