"That's the Boldero, all right," affirmed Captain Weston. "I recognize her, even if the name wasn't on her bow. Go right down on the bottom, Tom, and we'll get out the diving suits and make an examination."

The submarine settled to the ocean bed. Tom glanced at the depth gage. It showed over two miles and a half. Would they be able to venture out into water of such enormous pressure in the comparatively frail diving suits, and wrest the gold from the wreck? It was a serious question.

The Advance came to a stop. In front of her loomed the great bulk of the Boldero, vague and shadowy in the flickering gleam of the searchlight. As the gold-seekers looked at her through the bull's-eyes of the conning tower, several great forms emerged from beneath the wreck's bows.

"Deep-water sharks!" exclaimed Captain Weston, "and monsters, too. But they can't bother us. Now to get out the gold!"

Chapter Twenty-Three

Attacked by Sharks

For a few minutes after reaching the wreck, which had so occupied their thoughts for the past weeks, the adventurers did nothing but gaze at it from the ports of the submarine. The appearance of the deep-water sharks gave them no concern, for they did not imagine the ugly creatures would attack them. The treasure-seekers were more engrossed with the problem of getting out the gold.

"How are we going to get at it?" asked Tom, as he looked at the high sides of the sunken ship, which towered well above the comparatively small Advance.

"Why, just go in and get it," suggested Mr. Damon. "Where is gold in a cargo usually kept, Captain Weston? You ought to know, I should think. Bless my pocketbook!"
