“Mr. Bristow warned us not to come to Colon, general,” spoke up Shirley.

“He did?” exclaimed the general in surprise. “And why, pray?”

“Well, he said it wasn’t safe,” replied Shirley.

“Hm-m-m,” muttered the general, with a smile. “And did he tell you why?”

“No, sir.”

“I thought not,” laughed the general.

“But he told me, general,” put in Mabel.

The others looked at the girl in surprise, but Mabel bore up steadily under their scrutiny.

“What do you mean, Mabel?” demanded Colonel Ashton.

“You remember when he took me aside just before we were set adrift, father?” asked Mabel.
