“I will do so,” agreed Randall. “I suppose it is as good as settled that we are out of here without further effort?”
“Don’t be so sure.”
“Oh, you never fail. If I had half your resource and inventive faculty I would be a king among men.”
“Pshaw!” said Frank, testily. “Don’t talk nonsense!”
Over the ice-heap the young inventor went with the wires. Then he brought out small dynamite cartridges and placed one at the end of each wire. It was now that Randall clearly saw his purpose.
“Will not the explosion injure the machine?” he asked.
“It is not sufficient in quantity,” replied Frank. “If it was in a mass it might, but such small charges will only shake the ice to powder. Once we can clear it away from the wheels we are all right.”
However, the voyagers watched Frank’s work with some anxiety as well as interest. After awhile it was completed.
Then the young inventor connected the wires with the dynamos. A touch of the electric button and the charge was off.
There was quite a sharp explosion.
