"The nobility and frankness of his character," Don Mariano would say, "is enough to set aside all suspicion of his perfidy. His silence may be explained by the events through which he has been involuntarily borne, and by the political relationships that surround him." Gertrudis smiled sadly at the words of her father, but her heart was not the less torn with grief. In this unpleasant state of mind they passed three days, while journeying from Oajaca to the borders of the lake Ostuta. On the route they had met with no particular adventures nor encountered any obstacle; though from rumours that reached them from time to time--of the sanguinary deeds perpetrated by the ferocious Arroyo--they could not help experiencing a certain amount of apprehension. It was on the third evening of the journey that they reached the Ostuta river and had halted upon its banks at the spot already described. During the night Don Mariano, rendered uneasy by hearing certain confused noises in the adjoining forest, had despatched one of the trustiest of his servants in the direction of the crossing, with directions to reconnoitre the place. Two hours afterwards the domestic returned, with the report, that, near the ford he had seen numerous fires blazing along the bank of the river and on both sides of the ford. These could be no other than the fires of Arroyo's camp: since they had heard several times along their route, that the brigand was encamped at the crossing of the Ostuta. The servant added, that in returning from his reconnaissance he was under the belief that some one had followed him, as dogging his steps through the forest. It was for this reason that Don Mariano had caused the fires of his bivouac to be extinguished, and had so suddenly taken his departure from the place. By going some distance down the river, and making the circuit of the lake into which it flowed, the servant of Don Mariano believed he could find a crossing, by which they might reach the hacienda of San Carlos on a different road. Although this detour would make their journey nearly one day longer, it would still be preferable to falling into the company of Arroyo and his brigands. Among all the places in America, sacred to the worship of the native races, perhaps none enjoys a greater celebrity than the lake of Ostuta, and the mountain which rises up out of the bosom of its waters. The mountain is called Monopostiac, or the _Cerro encantado_ (enchanted hill). It has long been the locale of Indian tradition; and the singularly lugubrious aspect of the lake and its surrounding scenery would seem to justify the legendary stories of which it has been made the scene. It was to the borders of this lake, that the necessity of seeking his own and his daughter's safety, was now conducting Don Mariano de Silva.
