When Dick reached the street he saw nothing of Sam.  He looked up and down, and then walked slowly in the direction of Broadway.  On the corner he came to a halt.

“He must be somewhere around,” he mused.  “Perhaps I’d better go back and wait for him.”

“Dick!” The cry came from Sam, as he arrived on a run.  “Did you learn anything?”

“Not much.  But you look excited, Sam.  What’s up?”

“I think I saw Crabtree!”

“You did!  Where?  Why didn’t you collar him?”

“I didn’t get the chance,” returned the youngest Rover, answering the last question first.  “It was on the corner below here.  I was standing in a doorway, watching up and down, when I saw a tall man come along slowly.  He halted at the corner and presently another man came out of the side street and touched him on the arm.  The second man wore a heavy beard and a slouch hat and colored eyeglasses, but I am almost sure it was Josiah Crabtree.”

“Why didn’t you go up and make sure?  You could have pulled the beard from his face—­ if it was false.”

“Just what I thought.  But I decided that first I would listen to what the two men had to say.  When I got closer to the pair I made another discovery.

“What was that.”

“The first man had a pointed chin and the heaviest pair of eyebrows I ever saw.”

“What!” ejaculated Dick, and his mind ran back to the jail at Plankville, and to what had been said about the man who had visited Josiah Crabtree.  And then he thought of the mysterious automobile and its driver.

“Yes, I know what you think, Dick—­ and I think the same—­ that that man was the one who aided Crabtree to escape from jail,” said Sam.

“What did the men say, Sam?”

“I didn’t get a chance to listen.  As I was coming up I saw the first man give the second man some money.  Then the second man looked up and saw me, and shoving the money into his pocket, he dove across the street and into the crowd.  That made me feel sure it was Crabtree, and I ran after him pell-mell.  I followed him for about half a block.  But the crowd was too much for me, and he got away.  I was going to tell a policeman, but then I thought he couldn’t do any more than I could, and I made up my mind I’d wait for you.”

“What became of the other fellow—­ the man with the pointed chin?”

“I don’t know.  He went off somewhere while I was after Crabtree—­ if it was Crabtree,” answered Sam.

“Show me which way Crabtree went,” said Dick, and the brothers walked in the direction the fugitive had taken.  But, though they spent over an hour in looking for the man, not a trace of him could be found.

“Well, this proves one thing anyway,” said Dick, as he and Sam started on the return to the hotel.  “Crabtree is in league with Pelter, Japson & Company.  If he wasn’t, he wouldn’t show himself so close to their offices.”

“Just what I think,” returned his brother.  “And another thing, Dick; I think that man with the pointed chin is in with the brokers, too.”
