"We will test the Cardite in this small motor first," said Mr. Roumann,
as he pointed to a machine in the projectile used for winding a cable
around a windlass when there was necessity for hauling the _Annihilator_
about, without sending it into the air.
Into the receptacle of the motor, the German professor placed some of
the wonderful red substance he had secured from Mars. Then he closed
the heavy metal box that held it, and, looking about to see if all was
in readiness, he motioned to those watching him that he was about to
shift the lever that would start the motor.
"If it works as well as I hope it will," he said, "it ought to pull the
projectile slowly across the shop--a task that would be impossible in a
motor of this size, if operated by electricity, gasoline, or any other
force at present in use. And, if this small motor will do that, I know
the large ones will send us through space to the moon. All ready, now."
Slowly the professor shoved over the lever, while Jack, Mark and the
others watched him carefully.
