Two minutes later the square sail was hoisted, and the foot boomed out on the port side. Every eye was now fixed on the brigantine, but to their disappointment they saw that she was still, though very much more slowly, drawing ahead. "That is just what I feared," Frank said, in a tone of deep vexation. "With those big yards I was certain that she would leave us when running ahead before the wind. However, there is no fear of our leaving her. What are we doing now? Seven knots?" "About that, sir, and she is doing a knot better." "What do you think that she will do now, Hawkins?" "I don't see what she has got to do, sir. If she were to get five miles ahead of us, and then haul her wind, she would know that she could not go away from us, for we should be to windward; and we are evidently a good bit faster than she is when we are both close hauled. The only other thing that I can see for her to do is to run straight on to Port au Prince. At the rate we are going now she would be in soon after daylight tomorrow. We should be seven or eight miles astern of her, and he might think that we should not venture to board her there." "I don't think that he would rely on that, Hawkins. Now that he knows who we are, he will guess that we shall stick at nothing. What I am afraid of is that he will lower a boat and row Miss Greendale and her maid ashore. He might do it either there, or, what would be much more likely, row ashore to some quiet place during the night, take his friend and two or three of his men with him, and leave the rest to sail her to Port au Prince." "I don't think that the wind is going to hold," the skipper said, looking astern. "I reckon that it will drop, as it generally does, at sunset. It is not blowing so hard now as it did just before we wore round." In half an hour, indeed, it fell so light that the Osprey was standing through the water only at three and a half knots an hour. The light wind suited the Phantom, with her great sail spread. She had now increased her lead to a mile and a half, and was evidently leaving them fast. "There is only one thing to be done, George. We must board them in boats." "I am ready, Major; but it will be a rather risky business." Frank looked at him in surprise. "I don't mean for us, sir," George said, with a smile, "but for Miss Greendale. You may be sure that those fellows will fight hard, and as we come up behind we shall get it hot. Now, sir, if anything happens to you, you must remember that the Osprey will be as good as useless towards helping her. You as her owner might be able to justify what we are doing, but if you were gone there would be no one to take the lead. Carthew would only have to sail into Port au Prince and denounce us as pirates. I hear from the pilot that these niggers have got some armed ships, and they might sink us as soon as we came into the harbour, and then there would be an end to any chance of Miss Greendale getting her liberty."
