"What was it?" asked Russ, preparing to make a note.
The machinist gave it to him.
"Now if we can only trace it!" exclaimed the young inventor.
"I guess I can help you out, friend," broke in their own taxicab chauffeur. "I've got a list of all the cabs in New York, and the companies that run them." Rapidly he consulted a notebook, and soon had the desired information. The office of the company was not far away, and Russ and the girls were soon speeding toward it. What the next move was to be no one could say.
The manager remembered the call that had come in. Two men had come with a messenger boy to engage a cab to go to the address of the machine shop.
"And who were the two men?" asked Russ.
The manager described one whom Ruth and Alice had no difficulty in recognizing as Simp Wolley.
"The other man was shorter and not so well dressed," the cab manager went on.
"Bud Brisket!" exclaimed Russ. "I know him. Now the question is: Where did they take my model?"
"There I'm afraid I can't help you," said the manager.
