"I will leave you with the wounded here, doctor, with four of my men to help you. We are so littered up that we could hardly work the guns, and as you see, three of them were dismounted by the explosion; besides, the prize alongside would hamper us, therefore I will take the rest of the men on board the brigantine."

"I think that will be a very good plan, my lad," the doctor replied. "I quite agree with you, that with the spars and wreckage on one side and the prize on the other, you are practically helpless."

The men were at once set to work bringing up powder cartridges from the magazine; grape and round-shot they would find on board the brigantine.

In ten minutes the guns of that craft were reloaded. The two bodies of men from the batteries had by this time reached the storehouses. Not a shot had been fired, but a minute later there was a loud word of command, followed by a fierce yell, and in a moment both parties were engaged, a heavy fire being opened upon them from every spot of vantage on the hillside in front of them.

"Now, my lads, give them a dose of grape!" Nat shouted. "I expect they are two to one to our fellows still. Train them carefully."

Gun after gun sent showers of grape among the hidden foe, who were for the most part lying behind the cactus hedges of the gardens that surrounded the huts. The three forward guns assisted Mr. Hill's party, while the others aided that commanded by Needham. Although but four men to a gun, the sailors worked so hard that the pieces were discharged as rapidly as if they had been manned by a full complement, and their effect was visible in the diminution of the enemy's fire, and by the line of smoke gradually mounting the hill, showing that the pirates were falling back, while the cheers of the sailors and marines as they pressed steadily upwards, rapidly plying their muskets, rose louder and louder. Near the upper edge of the cleared ground the pirates made a stand, but the fire of the guns proved too much for them, and they took to the forest. Presently a sailor ran down to the shore.

"The first lieutenant says, sir, will you please continue your fire into the forest. He is going to cut down all the hedges and fire the huts, so that they will have to pass over open ground if they attack again."

"Tell Mr. Hill I will do so," Nat shouted back.

It was not long after the fire had been turned in that direction before the puffs of smoke that darted out from the edge of the forest ceased altogether. The sailors could now be seen slashing away with their cutlasses at the lines of cactus hedge, while the huts that still stood were speedily in flames. Numbers of women and children now came down to the shore, where they were placed in charge of six of the marines and a non-commissioned officer. A quarter of an hour later, while Nat was watching what was going on on shore, one of the men touched him.

"Look, sir, they are going down to the batteries!"
