He reloaded, and, awaiting his opportunity, fired again full at the man's breast. O'Hara's hair nearly lifted the cap from his head, when he saw his foe sitting unharmed, and as scornful as though no bullet could wound him. The bravest man has his weakness, and the greatest weakness of such characters as the man we are dealing with is their superstition. O'Hara verily believed the man at whom he had fired possessed more than mortal attributes, and, far more frightened than he would have been had a score of Shawnees sounded their war-whoop in his ears, he made a low whistle as a signal for Dick and Dernor to come up. In a moment they were beside him, curious to know the cause of his firing.

The next flash of lightning showed three hunters intently staring toward a man who was sitting composedly on a stump, and staring back at them with equal intensity.

"You all seen him, didn't you?" asked Tom, in a whisper. Receiving an affirmative answer, he added:

"Let's all aim square at his breast, and then we'll be sure that one of us at least will hit him. If that doesn't finish him, there's no use of trying."

For the third time, the mysterious being braved the deadly bullets, this time from three separate rifles, and for the third time he was seen sitting, unharmed and contemptuous, upon the stump.

"It's all a waste of powder," said O'Hara. "We might pour a broadside from a brigade into him without making him wink."

"Let's go up and take him," said Dick.

"He'll take us," said O'Hara, who was not ashamed of his fright in such a case as this.

"Fudge! don't be frightened; come along. I'll lead."

Thus strengthened, O'Hara moved on behind the two others. Most assuredly the mysterious personage would have been captured, had not the lightning, which continued to act the part of illuminator, discovered their approach to him. His feet were instantly seen to twinkle in the air, and he whisked off the stump as quick as thought, and disappeared. To make sure, however, the Riflemen passed their hands over the stump, but of course found nothing. The booming of the thunder had been so continuous, that the reports of the rifles had not awakened the settlers, and the three hunters conversed together without fear of disturbance.
