"Now, Mr. Turnbull, get the two guns right aft, so as to fire over the taffrail. We must see if we cannot knock some of her spars away. As soon as you have moved the guns let all hands, except those serving them, go forward and lie down there. The weight of the guns will put her rather by the stern, and I don't want to let that fellow come any nearer to us. She is in her best trim now."

As soon as the guns were ready they opened fire. The brigantine answered with her bow-chaser, but, as she was obliged to yaw each time she brought it to bear, she presently ceased firing.

"We are gaining on her, sir," Lippincott said, as he watched the pirate through his glass.

"Yes, and sailing fully a point nearer to the wind than she does. Get a stay-sail fastened to a rope, and drop it over close to the bow. I don't want to run away from her. If she found that we were too fast for her she would give up the chase, and go back to the prize. I want her to gain just enough to encourage her to keep on. She is a fast craft, but we are faster. We shall be able to manage her, providing she does not knock away any of our spars."

The start the schooner had made had at first widened the distance between them, and there was now a mile and a quarter of water separating them. The brigantine was hulled several times and her sails pierced, but her spars were still intact. She was permitted to gain until she was little more than half a mile astern, but the schooner had weathered on her, and was now nearly half a mile to windward.

"If we had an open sea on this side instead of the land," Turnbull said, "and were to cut away that sail, they would not see us again."

"No; they must have come to the same conclusion. As it is, they no doubt think that our clawing out to windward is of no advantage to us. Now, get another gun over to the larboard side. It is lucky that there is a spare port there. We must make an effort to knock one of his spars out, or he may cripple us." For by this time the brigantine had again opened fire. "Let the three best shots we have got lay the guns on her mainmast. Tell them to train them rather high, so that if they miss the mark they may cut one of the halyards, which will give us all the start we want."

The guns were run into their position on the broadside. "Don't hurry over it," Nat said; "let each fire as his gun comes to bear." There was a crash and a cry as he spoke; a ball had gone through the Arrow from side to side, tearing jagged holes through her bulwarks, one of the sailors being struck to the deck by a splinter. No one spoke, every eye being fixed on the guns. These were fired almost together. There was a pause for a second or two, and then a burst of cheering as the gaff of the great mainsail of the brigantine was seen to collapse.

"It is hit close to the jaws," Turnbull, whose glass was levelled on the pirates, exclaimed.

"Cut away that sail in the water!" Nat shouted. "Up with your helm, men, and bring her round. That is right," he went on as the schooner came up into the wind and payed off on the other tack. "Now, slack away her sheets!"
