“Evaporated nothing!” explained John angrily. “The car is gone. I don’t know what George and the fellows will say. We have lost two cars now instead of one. I don’t understand how it could have been taken away without our knowing it.”

“That isn’t nearly so important,” suggested the tramp, “as the fact that it is gone. There isn’t any car here.”
