It was, then, with a feeling of no small concern, that the pirate heard the lookout shout on the afternoon referred to, "Sail ho!"

"Where away?"

"On the lea beam."

The course of the frigate was at once changed, and she ran down towards the strange sail.

"A schooner, sir," observed the second lieutenant to Mr. Mulroy.

"It looks marvelously like the Foam, alias the Avenger," observed the latter. "Beat to quarters. If this rascally pirate has indeed been thrown in our way again, we will give him a warm reception. Why, the villain has actually altered his course, and is standing towards us."

"Don't you think it is just possible," suggested Henry Stuart, "that Gascoyne may have captured the vessel from his mate, and now comes to meet us as a friend?"

"I don't know that," said Mulroy, in an excited tone; for he could not easily forget the rough usage his vessel had received at the hands of the bold pirate. "I don't know that. No doubt Gascoyne's mate was against him; but the greater part of the crew were evidently in his favor, else why the secret manner in which he was deprived of his command? No, no. Depend upon it, the villain has got hold of his schooner and will keep it. By a fortunate chance we have again met; I will see to it that we do not part without a close acquaintance. Yet why he should throw himself into my very arms in this way, puzzles me. Ha! I see his big gun amidships. It is uncovered. No doubt he counts on his superior sailing powers, and means to give us a shot and show us his heels. Well, we shall see."

"There goes his flag," observed the second lieutenant.

"What! eh! It's the Union Jack!" exclaimed Mulroy.
