shouted the elder Rover, and shook his fist at the fellow in the street.
"Dick, did it hurt you?" asked Dora, anxiously.
"Oh, it burst my little finger a trifle, that's all," was the reply. The finger smarted quite some, but Dick did not want to show it.
"We ought to go back and punch his head," was Sam's comment.
"Wonder if they'll try that game on the other auto," said Fred, as he arose to look back.
He saw the street rough throw a lighted firecracker at the other machine. It landed on the floor of the tonneau, but like a flash Tom was after it. The fun-loving Rover held it up, took aim, and sent it straight at the fellow who had first launched it. Bang! went the firecracker, right close to the rough's left ear. He set up a howl of pain, for he had been burnt enough to make it smart well.
"There, he's paid back," said Fred, and then the two automobiles passed on, leaving the roughs in the distance.
