as if at length he really felt himself in his element.

"Oh, Massa Bacra!" roared out Sambo, as soon as he could recover from
his astonishment enough to speak, "Oh, Senor! he white man neber go to
swim! Oh, de tiburon! he berry bad bite, come de shark; he hab berry big

eye in the direction in which the negro pointed; and, well skilled in
all the appearances of the water, under which he could see almost as
