But Pomp, chancing to glance up the mountain side, saw a thrilling sight.
High up above their position was a mighty bowlder of many tons weight.
And back of it he saw the forms of several men.
They were trying hard to start the huge bowlder from its place. Their purpose was quite plain.
The bowlder started on its career down the mountain, unless swerved in its course, would strike the Steam Man.
If struck by the tremendous weight little would be left of the machine.
“Golly sakes, Marse Frank!” cried Pomp, in utter horror. “Jus’ yo’ see dat trick of de greasers.”
Frank did see it and for a moment was overwhelmed with horror.
Then he acted quickly.
“Give them a shot, boys!” he cried to Barney and Pomp, as he sprung to the dasher of the wagon.
