“There’s no time for questions, Captain Harmon. Leave it all to me.”

“All right, Mr. Reade.”

By Harmon’s orders five of The Vigilants joined Frank Reade.

He led them aboard the steam wagon. Then he closed the door and seized the reins which connected with the throttle.

The Steam Man gave a shriek loud enough to perforate the ear drums of any one in the vicinity.

The monster with fiery eyes and all flame and smoke, with clanking thunderous tread plunging into the midst of the foe, was an apparition well to be feared.

Right into the midst of the savages the Steam Man ran.
