“I may be mistaken,” replied Jim, “but I don’t believe I am. In any case the morning will determine. I am for going ashore then, and will investigate.”

Watches were set for the night, and for each interval of two hours one of the boys was on duty. Tom was on deck during the darkest period between two and four, and shortly before the latter hour he noted at a distance, although he could not see the ship, the noise of machinery, and felt sure that a newcomer had entered the harbor.

None were surprised at early dawn to observe the Sea Eagle riding quietly at anchor well toward the inner shore of the harbor, and some two and one-half miles distant.

Alongside of the Sea Eagle was a boat of nondescript appearance, the one they had seen the night before, and it was evident that the masters of the two ships had business of importance in hand.

“By Jove, old fellow,” cried Berwick, addressing Jim, “you were right after all. It is her, all right. We had better be getting ready.”

“Better go fully armed,” advised the professor. “You know that they are a pretty tough lot.”

“Tough enough,” agreed Berwick, “but I think we can take care of ourselves. I am not afraid to tackle anyone except that fiend of a Mexican. He is so little and slippery that I never feel quite safe when he is around.”
