"A triplane!" repeated Tom. "Yes—it is—and it's the airship of Andy Foger! Our rivals are on our track!"

He continued to gaze upward as the triplane shot forward, the noise of the motor being plainly heard. Then, with howls of fear, the Indians turned and fled. The rival airship had vanquished them.
