It was, in fact, just about that hour--as Don Cornelio could tell by the moon; but the observation did not hinder him from shuddering afresh at the mysterious sounds. From his elevated position he could see afar over both land and water; but no spire of village church or hacienda was visible--nothing but the sombre surface of the lake, the spray of the far-stretching forest, and the desert plains in the distance. The tolling again vibrated upon the air; and Don Cornelio was now convinced that it was from the lake itself, or the enchanted mountain in its midst, that the sounds proceeded. It seemed as if it was a signal, to awaken the Indian divinities from their sleep of ages! The moon was still rising higher in the heavens, and her brilliant beams broadly illumined the lake, even penetrating through the thickly-set stems of the reeds that bordered it. Certain vague noises that had from time to time fallen upon the ear of Don Cornelio, while half slumbering, now that he was awake, were heard more distinctly; and after a little while these sounds became converted into prolonged and dismal howlings, such as he had never before heard in his life. Upon just such another night he had been sorely frightened by the howling of jaguars; but all the tigers in the world could not have produced such a frightful noise as that with which his ears were now assailed. It was a chorus of voices entirely new to him, and that seemed to proceed from the powerful lungs of some gigantic creature hitherto unknown. As thoughts of the supernatural came into his mind, the Captain shivered through his whole frame; and had he not been tied to its branches, he would certainly have fallen from the tree. His horse, standing below, appeared fully to partake of his terror; for after dancing about, and causing the branches to crackle, the animal at length broke away from its fastenings, and, galloping off, joined company with the horses of Costal and Clara that stood nearer the edge of the water. The terrible howlings, combined with the mysterious tolling of the bell, produced upon the mind of Don Cornelio other impressions besides those of mere dread. He began to believe in a supernatural presence; and that the sounds he heard were the voices of those pagan divinities whom Costal had the boldness to invoke. Captain Lantejas was not the only person whom these strange noises had inspired with fear. At little more than gunshot distance from him, and hidden behind the trees, could be seen a number of men closely grouped together, and whispering their fears to one another. It need scarcely be said that they were the domestics of Don Mariano, who had counted with equal terror and astonishment the twelve strokes of the mysterious midnight bell. Their master, too, had heard the tolling, and was vainly endeavouring to account for the singular phenomenon.
