Continuing their course, in a few moments they were able to make out her hull against the white background of the beach, and then the two cabin windows in her stern. Through these, lights were shining, that in two broad bands were flung far over the surface of the water. In the darkness, the vessel might have been likened to some gigantic whale that had risen a moment, and was bending its huge eyes to reconnoitre the surface of the sea. "We must change our course," muttered Costal. "If the canoe gets under that light, some sentry on the quarterdeck may see us. We must make a detour, and approach from the other side." In saying this the Indian shifted the rudder, and turned the head of the craft into a new direction, while the rowers still continued to ply their muffled oars. The sharks turned at the same time, and kept on after the canoe, as could be told by the luminous traces left by their viscous bodies in passing through the water. Beyond, the surface was sparkling with phosphoric points, as if the sky, now covered with a uniform drapery of dark clouds, had dropped its starry mantle upon the sea. At intervals there came a slight puff of wind, and the water curling under it glanced more luminously; while an occasional flash of lightning announced that the clouds above were charged with electricity. In all these signs Costal recognised the precursors of a storm. The canoe had now passed far out of sight of the barges, and was circling around, to get upon the other side of the schooner--still followed by five of the shining monsters of the deep. Both Costal and the Captain believed themselves too far distant from the schooner to be seen by any one aboard when all at once a brilliant light enveloped the Spanish vessel, revealing her whole outlines from stem to stern. Those in the canoe had just time to perceive that it was the blaze of a cannon, when the report followed, and the hissing of a ball was heard. Almost on the instant the little craft received a terrible shock; and, in the midst of a cloud of spray thrown around it, the two rowers were seen tumbling over the side and sinking below the surface of the water. Two of the sharks disappeared at the same moment! Costal, seated in the stern, at once perceived that the canoe no longer obeyed the rudder; and Lantejas, who was more amidships, saw to his horror that the vessel was sinking at the forward part, where she had been struck by the ball. "_Por los infiernos_! an unlucky shot!" cried Costal. "What will be the result?" anxiously demanded Lantejas. "Why, a very simple thing: the bullet has crushed in the bow of the craft, and she will go down head foremost, I suppose." "_Por Dios_! we are lost then!" cried Don Cornelio in a voice of terror. "Not so sure of that yet," calmly returned Costal, at the same time rising and stepping forward in the canoe. "Keep your place!" whispered he to Lantejas, "and don't lose sight of me."
