The chief was prompt to act upon the suggestion. He and Atkins sprang behind the breastwork, and, before the midshipman could make up his mind what they were going to do, the stones were flying about him in a perfect shower. It would have been utter folly to stand longer upon the bridge in that exposed position, and, without waiting for a second volley, the officer turned and took to his heels.

"Hurrah for Governor Barton and the Crusoe men," shouted Sam. "You needn't talk to us about surrenderin', 'cause we ain't them kind of fellers, as I told you once before to-night. Chuck the bridge into the gully, Atkins."

If the chief imagined that he had disposed of the attacking party, he soon discovered his mistake. They were by no means defeated simply because their commanding officer had been driven from his position on the bridge. They had come there to capture the pirates, and they knew that two of them carried revolvers in their pockets. If the knowledge of that fact was not enough to turn them from their purpose, they were not likely to be frightened away by such missiles as Sam and his man had discharged at them. They were sharp enough to know that the bridge was the key to the enemy's position, and that much depended upon their ability to prevent Atkins from carrying out the governor's order. Stones were plenty on their side of the chasm, and there was also nearly half a bushel of potatoes left of those Sam had used against the mutineers. They were prompt to follow the example set them by the enemy, and, when Will Atkins ran forward to throw the bridge into the chasm, the order to halt, which he disregarded, was enforced by a volley of stones and potatoes that made the path in the vicinity of the bridge so uncomfortable that the Crusoe man was glad to retreat.

"Go on," thundered the governor. "That bridge must come down."

"Well, you can throw it down yourself," retorted Atkins "I ain't in no hurry to be hit by them taters an' rocks."

"Keep away from that bridge," said the midshipman. "Harding, if you and your three friends will act as artillery-men, we'll charge across and capture those fellows—the Crusoe men, I mean. Of course we can't arrest the robbers unless we can take some advantage of them; but we can keep them in here until we can send word to Mr. Grimes, and I don't think they will dare use their revolvers on him. If they find that they are fairly cornered, they won't have the courage to resist an officer of the law."

"But how can we keep them in?" asked Bill.

"Easy enough. If they attempt to come across the bridge we'll pepper them with stones. If they return to their vessel, and go out the other way, we can't help it. That's Harry Green's business. Simmonds," he added, "go down and report to the first lieutenant that we have found the pirates, that the robbers are with them, and that we are preparing to attack them."

The midshipman was almost on the point of adding: "And tell him that he had better send for re-enforcements and keep a bright lookout for the Sweepstakes, for she may try to run by him;" but he did not say it, for he knew that it was no part of his business to instruct his superior officer. Harry was smart enough to attend to all such matters, and Richardson was sure that he would neglect no precautions to insure the capture of all the schooner's crew.

"Now," continued the young officer, when Simmonds had started off to obey the order, "open fire on them, and drive them into the bushes, so that they can't throw at us."
