“And if you had, you wouldn’t tell us, eh?”

“I’m not going to answer questions,” said Nic. “But mind this: if you find him, I won’t have him shot down.”

“Then he mustn’t shoot at us, sir,” said the man, smiling, “so you’d better send him word if you know where he is. Forward!” he cried, and the party trotted toward the Wattles, but turned off a little over half-way there, and to Nic’s horror he felt that they had hit upon the place where he and the convict parted that night just as the storm came on.
