A minute later, a large star-spangled flag was majestically fluttering at the stern of the brig. At the appearance of the United States colours, so audaciously hoisted, a shout of fury was raised aboard the Mexican corvette, which was taken up by the crowd assembled at the point, though it was impossible to tell, owing to the distance, whether they were shouts of joy or anger.

In the meanwhile the sun was beginning to rise, the morning was growing apace, and there must be an end to the affair, especially as the corvette, confiding in her strength, and now almost within gunshot, would not fail to open fire on the American vessel. Strange to say, the garrisons of the fort and the battery, as the Captain had foreseen, had allowed the brig to double the point without trying to stop it, which it would have been most easy for them to do, owing to the crossfire.

The Captain gave his lieutenant a sign to come to him, and bending down to his ear, whispered something in it.

"Eh, eh!" the lieutenant said with a hearty laugh, "That is an idea! By Jove! We may have some fun."

And, without saying another word, he proceeded forwards. On reaching the swivel gun he had it unlashed and carefully loaded, adding a ball and a grape shot to the ordinary charge. Bending over the sight he seized the screw placed under the breech, then making a sign to the men who stood on either side with handspikes, he began laying the gun slowly and with the utmost precaution, scrupulously calculating the distance that separated the two ships, and the deviation caused by the rolling. At length, when he believed he had attained the desired result, he seized the lanyard, fell back, and made a signal to the Captain, who was impatiently awaiting the termination of his proceedings.

"Attention!" the latter shouted; "Stand by, all."

There was a moment of supreme expectation.

"Is all clear?"

"Yes," the lieutenant replied.

"Ready about," the Captain ordered; "down with the helm! Ease off the jib sheets! Sheet home top sails! Sheet home lower sails! Haul the bowlines taut!"
