They carried the wounded man below, to be placed in Madeline's roomy cabin. Mr. Cumberford was not a surgeon, but there was no one aboard who knew more of surgery than he and so he went to Mason's side at once.

Ganza had struck the man with a knife of the stiletto type, the narrow blade of which had penetrated his side just above the hip joint. Mr. Cumberford's "first aid" outfit, which the captain was able to supply, enabled him to stop the bleeding, but he was unable to tell how serious the injury might prove. The man was in considerable pain, which Cumberford partially relieved with a hypodermic injection of morphine.

During this interesting period no one gave a thought to the escaped Mexican, but when nothing more could be done for his patient Cumberford left the girls to watch over him and walked into the cabin, where he found Mrs. Tupper sobbing as if in great grief while her husband sat in his favorite despairing attitude, his head bowed on his arms.

"What's wrong?" demanded Cumberford, in surprise.

"Wrong!" cried Tupper, lifting his head; "why, at any moment may come the crash of the explosion that will send us all to eternity. We—we can't escape it. It's inevitable!"

Cumberford looked at his watch.

"It's a quarter to twelve," he said. "The explosion was due at eleven."

"But the Mexican brigand—the pirate chief—the——"

"He has escaped, so there'll be no explosion at all. I believe he threatened to fire the ship; but he won't do that. Ganza's sole ambition is to capture this boat, so he can sail away from his countrymen, escape imprisonment, and perhaps become a really-truly pirate. Interesting, isn't it? Forget the explosion, Tupper; if you must worry, worry about our real danger."

"What is that, sir? What is our real danger?" cried Madeline's uncle, springing to his feet in a new access of terror.
