“Ah!”

“By Gad, it annoys me when I think of it,” continued Rex, feeling, by force of memory, once more the adventurer of fashion. “With the resources I had, too. Oh, a miserable failure! The days and nights I've spent walking about looking for Richard Devine, and never catching a glimpse of him. The old man gave me his son's portrait, with full particulars of his early life, and I suppose I carried that ivory gimcrack in my breast for nearly three months, pulling it out to refresh my memory every half-hour. By Gad, if the young gentleman was anything like his picture, I could have sworn to him if I'd met him in Timbuctoo.”

“Do you think you'd know him again?” asked Rufus Dawes in a low voice, turning away his head.

There may have been something in the attitude in which the speaker had put himself that awakened memory, or perhaps the subdued eagerness of the tone, contrasting so strangely with the comparative inconsequence of the theme, that caused John Rex's brain to perform one of those feats of automatic synthesis at which we afterwards wonder. The profligate son—the likeness to the portrait—the mystery of Dawes's life! These were the links of a galvanic chain. He closed the circuit, and a vivid flash revealed to him—THE MAN.

Warder Troke, coming up, put his hand on Rex's shoulder. “Dawes,” he said, “you're wanted at the yard”; and then, seeing his mistake, added with a grin, “Curse you two; you're so much alike one can't tell t'other from which.”

Rufus Dawes walked off moodily; but John Rex's evil face turned pale, and a strange hope made his heart leap. “Gad, Troke's right; we are alike. I'll not press him to escape any more.”

CHAPTER XXIII. RUNNING THE GAUNTLET.

The Pretty Mary—as ugly and evil-smelling a tub as ever pitched under a southerly burster—had been lying on and off Cape Surville for nearly three weeks. Captain Blunt was getting wearied. He made strenuous efforts to find the oyster-beds of which he was ostensibly in search, but no success attended his efforts. In vain did he take boat and pull into every cove and nook between the Hippolyte Reef and Schouten's Island. In vain did he run the Pretty Mary as near to the rugged cliffs as he dared to take her, and make perpetual expeditions to the shore. In vain did he—in his eagerness for the interests of Mrs. Purfoy—clamber up the rocks, and spend hours in solitary soundings in Blackman's Bay. He never found an oyster. “If I don't find something in three or four days more,” said he to his mate, “I shall go back again. It's too dangerous cruising here.”
