They had an excellent passage, and Mirpah bore up bravely. Some time after leaving Guernsey, an English steamer bound for the Islands passed them a few hundred yards to leeward. The clean-shaven young gentleman in black was watching the stranger keenly through his glass when an expression of surprise burst from his lips. "What is it, James? What is it that you see, my boy?" asked Mr. Van Loal.

"On yonder boat I see an old acquaintance of yours and mine."

The old man took the glass and scanned the passing ship, the passengers of which were scanning the Southampton boat eagerly in return, and had their faces turned full towards it. The old man laid down the glass after a minute's silent observation.

"James," he said in a solemn tone, "unless my eyes deceive me greatly, the mulatto, Cleon, is on board yonder ship."

"You are right, father. Cleon _is_ on board that ship. He was not killed, then, after all, in his encounter with Captain Ducie."

"Such a fellow as that takes a deal of killing. On one point we may be pretty sure: that by some means or other he has discovered Captain Ducie's whereabouts and is now on his track."

"Wants his revenge, perhaps."

"Wants to recover the Great Mogul Diamond, mayhap."

Madgin Junior laughed. "He will hardly succeed in doing that, father. Mr. Van Loal has been in the field before him."
