"We won't let 'em board," said the captain. "Thank God, we've a good deal more'n a hundred men now. I guess Keller'll warn 'em how strong we are. That may hold 'em back."

It was a schooner wind, and the Noank was going along, but she was not travelling so fast as were the vigorously pulled boats. It was a lesson in sea warfare to watch them and see how perfect was their discipline and the oar-training of their crews.

"That's the reason," remarked Captain Avery, "why England rules the sea. We'll have a navy, some day, and we'll beat 'em at their own teachin's."

The rescued prisoners had been having a hard time of it in the hold of the Bermuda trader, and they were beginning to feel desperate now at what seemed a prospect of being once more captured by the enemy. They went to the guns, and they armed themselves like men who were about to fight for their very lives. There was one piece that they were not allowed to touch, however, for Up-na-tan himself was behind the pivot-gun. He and Groot, in consultation, seemed to be carefully calculating the now rapidly diminishing distance between the schooner and the British boat-line.

This reached the Sinclair speedily, and its delay there was only long enough for reports and explanations.

"That's her armament, is it?" the lieutenant in command had said to Keller. "Stronger than I expected, but we can take her. Forward, all! She won't think of resisting us. Give her a gun to heave to!"

The longboat in which he stood carried a snub-nosed six-pounder, and its gunners at once blazed away. They had the range well, and their shot went skipping along only a few fathoms aft of the Noank's stern.

"Father," exclaimed Vine, "it won't do to let that work go on. We might be crippled."

"Give it to 'em, Up-na-tan!" shouted the captain. "Men! We won't be taken! We'll fight this fight out!"'

Loud cheers answered him, but it was Groot, the pirate, who was now sighting the long eighteen, and he proved to be a capital marksman.
