He started the engine by attaching the wires from the comparatively weak Daniell cells. Slowly it began to move, gaining speed, until finally the very floor shook from the great power and the rapidity of the motion.
It seemed incredible that the small current from the battery should develop such apparent power and I looked at Kennedy in amazement.
"There's a carelessly—or purposely—ill-balanced flywheel, I suspect," whispered Craig to me surreptitiously.
"Yes, but the power," I persisted.
He shook his head. Evidently he was not convinced, but had no theory, yet.
Adele Laidlaw looked at Craig questioningly, as though to read what he thought of it. Before her he betrayed nothing. Now and then she would look earnestly at Creighton. It was evident that she admired him very much, yet there seemed to be something about him that she did not quite understand.
Just then the telephone rang. Creighton stopped his machine and left us for a moment to answer the call, while the engine slowed down and came to rest.
Quickly Kennedy pulled out his watch and pried the crystal off the face. He walked over to a basin and filled the crystal with a few drops of water. Then he set it down on the table.
I looked at it closely. As nearly as I could make out, there seemed to be a slight agitation on the surface of the thin film of water in the glass. Craig smiled quietly to himself and flicked the water into the sink, returning the crystal to his watch.
I did not understand just what it was that Craig was after, but I felt sure that there was some kind of vibration that he had discovered.
