"Oh. I don't know."

"Well, I will wager that he does not. More than that, I'll venture that Hartwick, wherever he may be, cherishes a fierce desire for revenge, and longs for the day when he will be able to get back at Frank. Merry will hear from that chap again."

And there the subject was dropped.

Frank enjoyed the ride upon Nemo's back, for the horse seemed intelligent and something of a comrade. The boy talked to his mount as if the animal could understand every word he uttered.

He had ridden beyond the limits of the city before he noticed that Nemo was limping the least bit.

"What's the matter, old fellow?" asked Frank, with concern. "Have you hurt yourself some way?"

Nemo shook his head. It almost seemed that the animal was answering the question in the negative.

"You must have stepped on a stone," Merriwell declared. "Why, you are really beginning to limp in earnest!"

Frank immediately dismounted, after having decided it was Nemo's left hind leg or foot that was lame.
