He now saw a chance of evening matters up with the coon.

Unconscious of his danger, the diminutive darky went from one oil-cup to another, with the oil-can in his hand, filling them up.

As he was passing the dynamo behind which Barney crouched, the Celt passed a copper wire around his ankle and rapidly bound it there.

On went Pomp a few paces and paused at a point to be oiled.

The moment he touched the metal lid of the cup to open it, an electric shock flew through him that made him spring in the air.

“Ouch! Fo’ de lan’s sake!” he yelled. “Wha’ dat?”

He shook his fingers, glared at the oil-cup, and then pondered.

The wire Barney fastened to his leg was secured to one pole of the dynamo, and the Irishman had another wire from the other pole to the metal floor.

As the machinery was bolted to the floor, the moment Pomp touched any of the metal work, a complete circuit was made with his body, and a terrific shock was the result.

The Irishman chuckled over the success of his plan.
