Although he no longer suffered much from the attack of the ants, Piper found his every sense painfully alert. Through the opening at the front of the tent he could see the faint, dull glow of the coals, which grew dimmer until it finally faded completely. At irregular intervals the night seemed to breathe with puffs of air which set the leaves rustling as if they were whispering to one another. Off in the woods something stirred, and there was the barely perceptible cracking of a twig, as if it had been broken beneath a soft and stealthy foot.

Imagination was vigorously at work with Piper, and he fancied all sorts of creatures to be prowling about in the vicinity. He was vexed because close at hand his four comrades slept peacefully, while he remained thus exasperatingly wide awake.

Suddenly, far away from the bosom of the lake, came a long, low moaning cry that thrilled the wakeful lad from his toes to the roots of his hair, for there was something weirdly doleful and terrible in that sound. Instantly he thought of the ghost of the dead hermit, which was said to haunt Spirit Island, and his teeth began to chatter a little. Never had he imagined that a night in the woods could be so fraught with awesome and terrible sounds. He was tempted to awaken the others, but knew they would be angered and scoff at him if he did so. Of a sudden he thought of the gun, and, thrusting out his hand, touched the cold barrel of the weapon, which he had placed near by. Grasping it, he seemed to feel his courage returning.

“If anything comes around here it’ll get hurt,” he whispered to himself. “There won’t be any fooling about it, either. I’ll shoot.”

As if applauding this courageous attitude on his part, he heard a sudden clapping sound, which seemed to come rushing toward the tent and cease abruptly.

“Now what was that?” he speculated, sitting up and holding the gun across his knees. “It was something. I’d just like to know.”

Getting out of the blankets, he rose to a crouching position and stepped toward the front of the tent, the gun gripped fast in his fingers. The darkness outside was not nearly as deep as he had thought it would be, and he could plainly perceive the outlines of tree trunks near at hand. Holding his breath, he crouched at the tent opening, gazing one way and another.

A fresh strong breath of air swept over the point, moving the tree tops and picking up a swirl of ashes from the fireplace, so that the last remaining coals were uncovered and fanned into a glow. And then, within ten feet of the fire, close to the trunk of a tree, he saw what appeared to be a black human-like body, above which rose a ghastly white face with two huge burning eyes. Those eyes of fire, seeming to glare upon him, sent cold chills darting along his spine. Immovable as a statue, he crouched, the gun in his hand forgotten for the moment.

Once more from the vague and distant bosom of the lake came that dreadful, doleful cry; and, as if in answer, a hoarse voice, half human yet demon-like, seemed to burst from the creature with the glowing eyes.

Gasping, Piper pushed the catch of the hammerless with his thumb, flung the butt of the gun to his shoulder, levelled the weapon at that black figure with the ghastly face and fiery eyes, and pulled both triggers.
