In a moment a scream was heard down the valley, and all eyes were instantly turned that way.
An exclamation of horror burst from the lips of the two hunters and the four young sportsmen.
They saw the Aërial Demon coming up the valley toward them!
The women uttered a little scream, while Rainbolt burst into a hearty laugh, then he placed the horn to his lips and blew another blast.
At this juncture the Aërial Demon was directly over the camp, and as the blast of the horn pealed out, the horrid creature ceased its flight and settled down, down into the very midst of the excited group.
A cry of surprise, followed by a ringing laugh, pealed from every lip.
The mystery of the Aërial Demon was explained, and the two hunters and four young sportsmen felt no little ashamed of their fears of such a harmless, but after all, a rather mysterious contrivance of Rodger Rainbolt.
Let us analyze the Aërial Demon, the terror of the Indians:
First, it received its motive power of Echo, the eagle.
Second, its great arms, that beat and buffeted the air, were the eagle’s wings, and the screams that it uttered were Echo’s screams.
