"Yes, but Monsieur," persisted Jack, "I saw some one uncommonly like you going the other way, towards Laxted Cove."

"Ah, Monsieur Jack, ve have a proverb, 'In the dark all cats are gray.' Dat you see some vun, it is certain; but me—no, Monsieur Jack, how can it? I vas composing my poem—over dere."

CHAPTER VI

SIGNALS

In the course of the morning Jack received from a carrier a note summoning him to rejoin his ship at once. His cousins were sorry to bid him good-by, and, though he was eager enough to return to his duty, he was so much interested in the strange things that had happened since his arrival at Bastable Grange that he would have liked very well to remain a few days longer and try to unravel the mystery by which he seemed to be surrounded. Before leaving he took Arthur aside for a moment.

"Look here, youngster," he said, "keep your eye on De Fronsac. If he tries to pump out of you what we saw last night, tell him we saw a boat putting out to sea and wondered whether the smugglers were at work. Don't say a word about the man we saw put on board. Don't let him think we suspect him. And it will be as well to take a note of the days when he reels off poetry."

"All right.—I say!"

"Well?"

"His poetry is fearful rubbish, isn't it?"

"Never made any myself, but I fancy I could do as well as he. Good-by. Remember what I said."
