“It is my foot,” explained Juarez. “I expect I strained it when I fell. I can hardly walk.”

“Hardly!” exclaimed the professor when he examined Juarez’s foot. “It’s a wonder you walked at all. You have a dislocation. And your head, too?”

“Never mind that,” cried Juarez. “Never mind anything. We want to get after the pirates.”

“All in good time, Juarez,” replied the professor. “The first thing to do is to get you into shape again, for we shall need your help. Here, Tom, you get a hold of this leg. Hold it steady, now, ready.” With a little click the bone slipped back into place when the professor gave a pull and a little twist to the foot, but although Juarez’s face went white, he did not utter a sound.

“Now,” commanded the professor, “see if you can get some cold water, Jo, and Tom, you find something for a bandage. You’ll find some sail cloth among the stuff we brought in the boat.”

Tom was off in a second to return presently with a strip of cloth as Jo came up with his cap full of water. Tearing the material into strips and dipping them into the water, the professor soon had both Juarez’s head and foot bandaged in a way that gave him comparative relief.

“Now,” said the professor, “tell us about Jim.”

Whereupon Juarez told briefly of his journey that afternoon, and how, when trying to observe the approach of some strangers, he had fallen, and then he repeated the conversation he had overheard, and told how he had tried to get back to the shore in time to warn Jim of the impending danger. All listened intently and Tom could not avoid an occasional interruption to express his opinion of the steward.

“The villain!” cried Tom between his teeth, in a tone that boded ill for the man.
