"Big Feet! Big Feet! I see um Big Feet, Master!"

The next moment he threw himself from the rapidly moving locomotive. He might have been killed easily enough. But fortunately he landed feet first in the drift beside the rails, and remained upright as he slid down into the ditch.

Tom, glancing ahead again, saw the flash of a man in a checked Mackinaw running up through the open wood and away from the right of way. He could not be sure of Andy O'Malley's figure at that distance; but he could be pretty confident of Koku's identification.

And then, with a shock that gripped and almost paralyzed his mind, Tom saw again the switch ahead of the pilot of the Hercules 0001. The switch was open, and at the speed the electric locomotive had attained, if she did not jump the rails, it seemed scarcely possible that she could be stopped before hitting the bumper at the end of the siding!

Chapter XXII

A Desperate Chase

These moments were fraught with peril, and not alone peril to the huge machine that Tom Swift had built, but peril to those who remained in the cab of the electric locomotive, as her forward trucks struck the open switch.

There was a mighty jerk that brought a shout from Ned Newton's lips and a grunt from Mr. Damon. Tom clung to his swivel-seat, staring ahead.

The pilot of the electric locomotive shot over on the siding; the forward trucks followed, then the great drivers. The whole locomotive swerved into the siding, but for several breathless seconds Tom was not at all sure that the monster would not jump the rails and head into the ditch!
