A cry of alarm escaped his lips.
Several of the bandits had gone up on the gallery above the Terror, and were pushing over a huge rock that rested there.
Just as Jack looked up it fell.
The rock must have weighed a ton.
It came down directly toward the roof of the Terror.
Jack gave the starting lever a sudden jerk, and the stage suddenly darted ahead.
She was too late to escape injury, though.
With a sickening crush the rock struck the rear end of the roof, crushing it like an egg shell, and going down on the platform, it carried it and the steps away.
A howl of joy escaped the James Boys.
They thought the terror was destroyed.
