"Frankly, Merriwell, the chap I was chasing looked like Morton Agnew! I was in Mason & Fettig's, five or six blocks above, when some one came into the other room and passed a counterfeit ten-dollar bill on the proprietor. He discovered it while the fellow was going through the door, and gave a call. I ran to the door and saw the rascal—not well, you know, but a side glance—not much more than a flash—and I thought he was Agnew. Of course, I couldn't swear to it. I may have been mistaken. But to satisfy myself, I jumped into that automobile and gave chase. He saw I was pursuing him and he sprang into a cab. I was determined to overhaul the scamp and satisfy myself on that one point. Perhaps I ought not to mention the name, as I am so uncertain, and I shall not mention it to any one else."

Dunstan Kirk, the athletic and capable captain of the baseball-team, had come to admire and trust Frank Merriwell. He had seen enough to know that Frank could be trusted in any way and in any place.

"What do you think of it?" he asked.

"That there is no chance now of discovering whether your suspicions were true or false. Unless"—hesitatingly—"you should cause Agnew's arrest, and have him taken before the man who was cheated. Or you might tell the man your suspicions, and let him act in the matter."

"I am not certain enough!" said Kirk. "It's too bad he got away! The motorman couldn't have been in his pay?"

"If so, he has received his pay!" said Merry meaningly. "He went out of that seat on his head and struck hard. I think the motorman simply found the hansom unmanageable, for some reason. Those carriages take freaks at times."

"And your opinion about Agnew?"

"He isn't too good to do such a thing, and I have had reason to believe lately that he is hard up. He used to hold himself up by his winnings at cards, but he has cheated so outrageously and boldly that the students fight pretty shy of him."

"We're just wasting our time, I'm afraid!" Kirk grumbled, as the cab rattled on down the street.

"Hold on!" said Merriwell, looking through the window. "There is your green-liveried driver and your bay horse!"
