"Who's there?" demanded Christy Passford, sitting up in his bed, in the middle of the night, in his room on the second floor of his father's palatial mansion on the Hudson, where the young lieutenant was waiting for a passage to the Gulf. There was no answer to his inquiry. "Who's there?" he repeated in a louder tone. All was as still as it ought to be in the middle of the night, and no response came to his second inquiry. The brilliant young officer, who had just passed his eighteenth birthday, knew what it was even better than an older person to pass a whole night on difficult duty, without a wink of sleep, for he had been accustomed to spend a portion of every night in planking the deck on his watch; but at Bonnydale, his quiet home, far removed from the scenes of actual conflict, he was an industrious sleeper, giving his whole attention to his slumbers, as a proper preparation for the stirring scenes in which he was again about to engage.
