Larry was now all attention. Following out the instructions of Jay he carefully examined the trousers of the big diver. Yes, there it was; the telltale little pocket on the side of the right leg. Larry edged up closer to get a better look at it. There was a certain bulge to it as though it was well filled.

"Gee, you're a regular Beau Brummel of a diver with your fancy clothes," offered Seymour facetiously as he smiled up into the face of Weddigen.

"What do you mean, fellow?" blurted the latter, turning short to survey the Bridgeford seaman whom he remembered as one of the three he had encountered the day he and Jay had come together just outside Superintendent Brown's office.

"Why, with your pretty little side pockets," prattled Larry with a sickly grin.

With a flourish of the hand he indicated the bulging patch on the side of Weddigen's armor, and before the latter could intervene Larry swept his hand carelessly but unerringly over the pocket, giving it such a thrust that the button slipped through the stout canvas eye-hole. At the same time Weddigen clutched the pocket as though to cover it. But he was too late!

Instantly a half dozen glittering diamonds popped from the aperture and rolled on the deck of the Nemo, sparkling in the morning sun like the jewels of a monarch's crown!

"What do you mean, you big stiff," growled Weddigen in dismay as the treasure that he had filched from the strong box while yet in the wreck of the Dominion was revealed.

"What do I mean? I mean that you're a rascal and a thief," shot back Larry, fully convinced now that the sparklers were part of the loot that had been recovered from the lost British liner.

Immediately there was a great hubbub among the crew as they pounced upon the scattered diamonds, eager to retrieve them before they rolled overboard or were jostled below by the roll of the Nemo.

"You're a big fool and I'll break your face so soon as I get in trim again, that's what I'll do," snorted Weddigen in a rage.
