"In the first place, Jesse James owns a horse named Siroc which is unequaled in speed and intelligence by any horse in the world that I know of, and he can easily outfoot the fleetest animal that ever chased him."
"Well," asked Jack, "suppose an electric overland engine were to chase that remarkable quadruped, don't you think he might be overtaken? The engine I refer to can run at the rate of fifty miles an hour over rough ground."
"Any engine could last longer than a horse, and such a machine as you mention could outspeed that horse. But, of course, such an engine is an utter impossibility."
"You are mistaken," said Jack, quietly.
"How so?" asked Timberlake, with a puzzled look.
"Because I have got such an engine."
"You have?"
"Just finished building it."
"And it runs by electricity?"
"Entirely so."
