Thus did they continue altering their course until the studding-sails below and aloft were set by both, and the position of the schooners was changed; the Enterprise now being on the starboard instead of the larboard quarter of the Avenger. The relative distance between the two schooners was, however, nearly the same, that is, about three miles and a half from each other; and there was every prospect of a long and weary chase on the part of the Enterprise, who again kept away a point to near the Avenger.
Both vessels were now running to the eastward.
It was about an hour before dark that another sail hove in sight right a-head of the Avenger, and was clearly made out to be a frigate. The pirates were alarmed at this unfortunate circumstance, as there was little doubt but that she would prove a British cruiser; and, if not, they had equally reason to expect that she would assist in their capture. She had evidently perceived the two schooners, and had made all sail, tacking every quarter of an hour so as to keep her relative position. The Enterprise, who had also made out the frigate, to attract her attention, although not within range of the Avenger, commenced firing with her long-gun.
“This is rather awkward,” observed Cain.
“It will be dark in less than an hour,” observed Francisco; “and that is our only chance.”
Cain reflected a minute.
“Get the long-gun ready, my lads! We will return her fire, Francisco, and hoist American colours; that will puzzle the frigate at all events, and the night may do the rest.”
The long-gun of the Avenger was ready.
“I would not fire the long-gun,” observed Francisco, “it will show our force, and will give no reason for our attempt to escape. Now, if we were to fire our broadside-guns, the difference of report between them and the one of large calibre fired by the other schooner would induce them to think that we are an American vessel.”
“Very true,” replied Cain, “and, as America is at peace with all the world, that our antagonist is a pirate. Hold fast the long-gun, there; and unship the starboard ports. See that the ensign blows out clear.”
