aining bunks for sleeping, the middle
one was a combined dining room and kitchen, the cooking being done on an
electric stove, and the rear room was for storage.

In it water and provisions, arms and ammunition, tools and many other
useful articles were to be stowed.

There were two compartments--one under the sleeping room floor in which
stood the mechanism for running the Terror, and the other beneath the
store room floor, in which stood a small powerful dynamo which operated
automatically by a spring clockwork.

All the room lamps and the search-light derived their current from the
dynamo, while it worked the motor, and that in turn operated the driving
wheel machinery.

"It don't require a skilled electrician to see how the Terror operates."
said Jack, as he showed the sheriff the interior, "for I have based her
construction upon the simplest known principles."

"Oh, I can readily see how she ought to work."

"I'll give you an example," said Jack, seating himself behind the
steering wheel and pulling a lever.

That set the clockwork in motion, it spun the dynamo armature, a current
was generated, flashed into the motor, the shaft operated the machinery,
and the Terror rolled ahead.

When she reached the end of the room he reversed the lever and she
backed to the other wall.

He then ran her around the room in a circle, steering by the wheel, and
attained a tremendous velocity; he put on the brakes and she stopped
within a few feet, and he turned a switch that caused the search-light
and lamps in her to glow.

By the time he finished the sheriff was wild with admiration of the
extraordinary vehicle.

"For what purpose did you build her? he asked Jack, when they finished
maneuvering her, and alighted.

"Just for fun, I have plenty of money and leisure, and a strong liking
for building these electrical inventions."

"But why did you say she could catch Jesse James' horse Siroc?"

"Simply because I have made up my mind to do so?"

"What! Go to Missouri in pursuit of the James Boys?" asked Timberlake,
as he took up Jack's remark.

"Yes, sir. I or the bank have lost five thousand dollars by a mean trick
the bandit king played on me, and I mean to recover it."

"League yourself with the State Government against the outlaws, and you
may not only recover the stolen money, but you stand a mighty good
chance of winning the standing reward of five thousand dollars for the
arrest and conviction of the James
