“Never you mind, my boy. The clever magician waits till he has everything in order before he performs his trick.”

“Ben’s got something up his sleeve,” put in Tom. “I can always tell when he talks in that grand way. But there’s no use trying to make him tell us, Dave. The way to make an oyster talk is to pay no attention to it.”

Ben said nothing, though the temptation was great as the Argo reached the northern end of the island, where high rocks came down to the water.

Tuckerman admitted these were cliffs, but there were a number of them, and how was he to tell which was the one they wanted? They sailed slowly along, watching the shore and speculating as to what the message in the desk referred. And while the other three talked Ben sat silent, trying to picture what had happened to James Sampson there more than a century before.

Ben had a good imagination, and it led him to see Sampson as a servant of Sir Peter Cotterell, a faithful serving-man, who always did what his master told him. When the men of Barmouth threatened to take Sir Peter’s treasure the old Tory gave some of his most valuable possessions to Sampson, and the latter carried them to this end of the island where he had a small boat that should carry him to the mainland. When he reached the shore, however, he saw other Barmouth men patrolling the coast in their own boats and so his escape that way was cut off. With quick wit he hid the treasures in a cleft of the rock and blocked up the hiding-place. Ben could see it all, even to Sir Peter, in knee-breeches and wig, commending James Sampson when the man returned and related what he had done. “Good and faithful servant,” said Sir Peter; “the rascals are outwitted again!” And doubtless Sir Peter took Sampson into the dining-room and poured him out a glass of rum. Ben wasn’t sure about that; it might not have been rum; but rum sounded well, it smacked of old-time adventure. Yes, probably it was rum; and Sampson had wiped his mouth with the sleeve of his jacket and laughed with his master at the thought of the men of Barmouth sitting out there in their boats, like so many cats waiting outside a mouse-hole.

“Come out of it, Ben! Wake up!”

Ben looked up with a start. Tom was laughing at him. “Where are you, Benjie? A million miles away!”

“No,” answered Ben, “I was listening to Sir Peter talking to a man you don’t any of you know anything about.”

“Your precious mahogany man?” asked Tom. “Don’t tell me you learned something more about him while you were up at the house.”

“He means the man with the big feet,” said David. “Did you find his prints in the house?”
