Try as Tom did to get a glimpse of the mysterious passengers he was unsuccessful. He spent many hours in a night, and early morning vigil, only to have to do his sleeping next day, and it resulted in nothing.

"I guess they want to get on Mexican soil before any one sees their faces," spoke Ned, and Tom was inclined to agree with his chum.

They awoke one morning to find the sea tempestuous. The ship tossed and rolled amid the billows, and the captain said they had run into the tail end of a gulf hurricane.

"Two days more and we'll be in port," he added, "and I'm sorry the voyage had to be marred even by this blow."

For it did blow, and, though it was not a dangerous storm, yet many passengers kept below.

"I'm afraid this settles it," remarked Tom that night, when the ship was still pitching and tossing. "They won't come out now, and this is likely to keep up until we get to port. Well, I can't help it."

But fate was on the verge of aiding Tom in an unexpected way. Nearly every one turned in early that night for it was no pleasure to sit in the saloons, and to lie in one's berth made it easier to stand the rolling of the vessel.

Tom and Ned, together with Mr. Damon, had fallen into slumber in spite of the storm, when, just as eight bells announced midnight there was a sudden jar throughout the whole ship.

The Maderia quivered from stem to stern, seemed to hesitate a moment as though she had been brought to a sudden stop, and then plowed on, only to bring up against some obstruction again, with that same sickening jar throughout her length.

"Bless my soul! What's that?" cried Mr. Damon, springing from his berth.
