"I think so."

In a short time Tom, the captain, Mr. Sharp and Mr. Damon were attired in the diving suits, Mr. Swift not caring to venture into such a great depth of water. Besides, it was necessary for at least one person to remain in the submarine to operate the diving chamber.

Walking slowly along the bottom of the sea the four gold-seekers approached the wreck. They looked on all sides for a sight of the sharks, but the monster fish seemed to have deserted that part of the ocean. Tom was the first to reach the now disrupted steamer. He found he could easily climb up, for boxes and barrels from the cargo holds were scattered all about by the explosion. Captain Weston soon joined the lad. The sailor motioned Tom to follow him, and being more familiar with ocean craft the captain was permitted to take the lead. He headed aft, seeking to locate the captain's cabin. Nor was he long in finding it. He motioned for the others to enter, that the combined illumination of the lamps in their helmets would make the place bright enough so a search could be made for the gold. Tom suddenly seized the arm of the captain, and pointed to one corner of the cabin. There stood a small safe, and at the sight of it Captain Weston moved toward it. The door was not locked, probably having been left open when the ship was deserted. Swinging it back the interior was revealed.

It was empty. There was no gold bullion in it.

There was no mistaking the dejected air of Captain Weston. The others shared his feelings, but though they all felt like voicing their disappointment, not a word could be spoken. Mr. Sharp, by vigorous motions, indicated to his companions to seek further.

They did so, spending all the rest of the day in the wreck, save for a short interval for dinner. But no gold rewarded their search.

Tom, late that afternoon, wandered away from the others, and found himself in the captain's cabin again, with the empty safe showing dimly in the water that was all about.

"Hang it all!" thought the lad, "we've had all our trouble for nothing! They must have taken the gold with them."

Idly he raised his steel bar, and struck it against the partition back of the safe. To his astonishment the partition seemed to fall inward, revealing a secret compartment. The lad leaned forward to bring the light for his helmet to play on the recess. He saw a number of boxes, piled one upon the other. He had accidentally touched a hidden spring and opened a secret receptacle. But what did it contain?

Tom reached in and tried to lift one of the boxes. He found it beyond his strength. Trembling from excitement, he went in search of the others. He found them delving in the after part of the wreck, but by motions our hero caused them to follow him. Captain Weston showed the excitement he felt as soon as he caught sight of the boxes. He and Mr. Sharp lifted one out, and placed it on the cabin floor. They pried off the top with their bars.
