At that moment the hulk of the sunken ship loomed before him, but in spite of his eagerness for the treasure Phil’s feet lagged. If only he could find the gold first—then, calling himself all sorts of names he started forward again, making the best speed he could toward the wreck.

“Don’t be a fool,” he said, briskly. “The fellows on the Sea Rover have been dead long enough not to mind my company. Their stolen money isn’t doing anyone any good here at the bottom of the sea.”

As he clambered to the slanting deck of the vessel it seemed to him that the oxygen in the tank was becoming exhausted but he soon discovered that it was only his excitement that caused his labored breathing.

As he stood balancing on the slippery deck he took in with a quick glance the work that the dynamite had done. No need to worry about the hatch now! The whole upper deck had been torn to shreds and the interior of the vessel yawned toward him, a dark gaping hole.

With a feeling of one who is venturing into the unknown, Phil strove to pierce the gloom in the depths of that strange vessel. What did the blackness hide from him?

CHAPTER XVII
AN UNCANNY EXPERIENCE

Slowly, almost reluctantly, Phil lowered himself through the jagged aperture that had once been the deck of the ship. Without knowing what might be beneath him he let go his hold and dropped.

He landed heavily and, hampered by the suit, stretched himself full length on what he supposed to be the floor of the cabin. Flounderingly he got to his feet, the headlights throwing a weird radiance about him.

He looked about him and found, as he had supposed, that he was in a fairly good-sized cabin, probably that of the captain of the pirate ship. This would hardly be the place to look for the treasure but, deciding to overlook no chances, Phil prepared to make a thorough survey of the place.

It was a gruesome business, feeling about in that dark cabin, not knowing what awful thing the headlights might rest upon. But, on the other hand, suppose they should reveal a chest, containing a fortune of untold riches!
