By two o'clock the topsails of the brigantine could be again made out from the deck. She was still working along shore, and was on their port bow. "Another three hours and we shall be alongside of her," the skipper said; "and if I am not mistaken we shall come out ahead of her." "There is one advantage in the course we are taking, Hawkins. Viewing us, as she will, pretty nearly end on till we get nearly abreast of her, she won't be able to make out our rig clearly." By four o'clock they were within five miles of the brigantine. The wind then freshened, and laying her course as she did, while the brigantine was obliged to make frequent tacks, the Osprey ran down fast towards her. "They must have their eyes on us by this time," the captain said. "Though they cannot be sure that it is the Osprey, they can see that she is a yawl of over a hundred tons, and as they cannot doubt that we are chasing them, they won't be long in guessing who we are. Shall we get the arms up, sir?" "Yes, you may as well do so. The muskets can be loaded and laid by the bulwarks, but they are not to be touched until I give the order. No doubt they also are armed. I am anxious not to fire a shot if it can be helped, and once alongside we are strong enough to overpower them with our cutlasses only. With the five blacks we are now double their strength, and even Carthew may see the uselessness of offering any resistance." They ran down until they were within a mile of the shore, not being now more than a beam off the brigantine. Two female figures had some time before been made out on her deck, but they had now disappeared. It was evident that the Osprey was being closely watched by those on board the brigantine. Presently two or three men were seen to run aft. "They are going to tack again, sir. If they do they will come right out to us." Frank made no reply, but stood with his glass fixed on the brigantine. Suddenly he exclaimed: "Round with her, Hawkins!" "Up with your helm, Andrews. Hard up, man!" the skipper shouted, as he himself ran to slack out the main sheet. Four men ran aft to assist him. "That will do," he said, as she fell off fast from the wind. "Now, then, gather in the main sheet, ready for a jibe. Slack off the starboard runner; a couple of hands aft and get the square sail out of the locker. "Mr. Purvis, get the yard across her, lower her down ready for the sail, and see that the braces and guys are all right. "Now in with the sheet, lads, handsomely. That will do, that is it. Over she goes. Slack out the sheet steadily." "She is round, too," Frank said, as the boom went off nearly square. "We have gained, and she is not more than half a mile away." The manoeuvre had, in fact, brought the yachts nearer to each other. Both had their booms over to starboard. "Quick with that square sail," Frank shouted. "She is drawing away from us fast."
