Frank started and turned pale. He knew that this information, like that concerning Ned and the lieutenant, might be false, but he was anxious just the same.

“What peril is he in?” he asked, and the other smiled to think he had struck fire at last.

“Well, it seems that he is accumulating proof against the men who are said to be planning to destroy the big canal, over yonder, and is getting on the wrong track. The men he is about to accuse of complicity in the plot are justly indignant, and are preparing to dynamite his building in case any copy concerning them is sent to the composing room.”

“You seem to be conversant with the affairs of these men,” Frank suggested, with a frown. “Are you one of the men who sneaked into our home and chloroformed father and stole my necklace?”

“I heard something about that,” the Colonel said, “and wondered at it. However, we are not discussing past incidents. What I desire you to do is to communicate with your father, in the cipher you sometimes use in your correspondence, and inform him of what I have just told you. Say to him that he is mistaken in the men, and that his building will be destroyed if he attempts to publish the alleged facts he has on hand.”

“I think,” Frank said, “that I can trust his good judgment. He can take care of himself.”

“Then you refuse to send the message?”

“I certainly do.”

“You seem to be a fat, healthy sort of a boy,” laughed the other, changing the subject, apparently, with a suddenness which astonished the boy.

“I have no cause to complain,” Frank said.
