“They didn’t do nothing,” declared the driver. “It was me who came near running into them.”

“Hang it!” burst from Merriwell. “I don’t care about that! I want you to follow them!”

“What for?” asked the driver.

“Because I tell you to, you stupid blockhead!” Frank almost roared. “It will be worth ten dollars to you if you keep them in sight.”

“I will do it or kill my horses!” declared the man.

The other cab had obtained quite a start while Frank was urging the driver to start in pursuit.

“It’s a hot toime we’re in fer, me b’y,” said Barney.

“It’s a hot chase I propose to give them,” came determinedly from Merriwell’s lips. “Fortune has favored us, and now we must not let them get away.”

“Pwhat do yez mane to do afther ye catch thim?”

“Don’t know now. I’ll be able to tell better when we catch them.”
