That night the darky retired at his usual hour. It had been his first watch and it was past midnight when he turned in.
Barney was on duty for the rest of the night. The Celt waited until all was quiet and he was assured that Pomp was sound asleep.
Then he crept down into the cabin.
He brought from the dynamo-room the two long coils of invisible wire. These were fastened to screws connected with the dynamos.
Reaching down, Barney slipped a small end of the wire into each shoe of the darky’s. This he fastened in such a way that it could not be easily removed, and yet would not interfere with putting the shoes on.
He made a complete circuit, and then turned on the current.
Now was the time for the fun to begin.
It was a peculiarity of Pomp’s that when suddenly awakened his first move was to don his shoes.
He would not more have thought of leaving his bunk without his shoes on than of flying to the moon.
So Barney had the wires well laid. He made sure that everything was all ready.
