dismissed them, and was conversing with Don Tadeo, when the door was thrown open, and a man entered. On seeing him, they uttered a general cry of joy and astonishment. It was Curumilla!

"At last!" Louis and Don Tadeo exclaimed.

"I am here!" the Ulmen replied, sorrowfully.

As the poor Indian seemed quite exhausted with fatigue and want of food, they made him sit down. In spite of all his Indian stoicism, Curumilla literally seized the food as soon as it appeared, and devoured it greedily.

As soon as the keenness of his appetite was a little abated, Curumilla related the full details of all that had happened since his departure from the camp, the manner in which he had delivered the young lady, and how, an hour after, she had been recaptured by her enemies. When he quitted Doña Rosario the brave Indian had only kept at a sufficient distance from her to avoid being himself taken by her ravishers.

Don Tadeo and the count warmly thanked him.

"I have done nothing yet," he said, "since all must be begun again; and now," he added, "it will be more difficult, for they will be on their guard."

"Tomorrow," Don Tadeo replied, warmly, "we will set out all together on the track."

"Yes," the chief said, "I am aware you are to depart tomorrow."

The three men looked at each other with astonishment; they could not understand how the news of their movements should be known.

"There are no secrets for Aucas, when they wish to know them," the chief said with a smile.

"It is impossible!" Don Gregorio exclaimed angrily.

"Let my brother listen," the chief replied quietly. "Tomorrow, at sunrise, a detachment of a thousand white soldiers will leave Valdivia to conduct the prisoner Bustamente to Santiago. Is it not so?"

"Yes," Don Gregorio replied, "I must admit that what you say is correct."

"Well," said the Ulmen smiling, "I cannot deny that the man who gave me these details had no suspicion that I overheard him."

"Explain yourself, chief, I implore you!" Don Tadeo cried; "we are upon burning coals."

"I have told you that I followed Antinahuel's party; I must add that occasionally I got before them. The day before yesterday, at sunrise, the Black Stag, who was left with Antinahuel's warriors during his absence, was on the prairie of the treaties, and as soon as he saw his chief, galloped to meet him. As I had no doubt that these two men, during their conference, would allow some words to escape that might afterwards be of service to me, I drew as close to them as possible, and that is the way they placed me in possession of their projects."

"Of their projects?" Don Gregorio asked, "are they mad enough, then, to think of attacking us?"

"The pale woman has made Antinahuel swear to deliver her friend, who is a prisoner."

"Well! and what then?"

"Antinahuel will deliver him."

"Ay, ay!" said Don Gregorio, "but that project is more easily formed than executed, chief."

"The soldiers are obliged to traverse the Canyon del Rio Seco."

"No doubt they are."

"It is there that Antinahuel will attack the palefaces with his mosotones."

"Sangre de Cristo!" Don Gregorio exclaimed, "What is to be done?"

"The escort will be defeated," Don Tadeo observed.

Curumilla remained silent.

"Perhaps not!" said the count: "I know the chief; he is not the man to cause his friends embarrassment without having the means of showing them how to avoid the peril he reveals to them."

"Unfortunately," Don Tadeo replied, "there exists no other passage but that cursed defile; it must absolutely be cleared, and five hundred resolute men might not there only hold a whole army in check, but cut it to pieces."

"That may be all very true," the young man replied persistently; "but I repeat what I have said—the chief is a skilful warrior, his mind is fertile in resources."

Curumilla smiled and nodded.

"I was sure of it!" Louis cried. "Now then, chief, speak out! Do you not know a means of enabling us to avoid this dangerous passage?"

"I will not certify that," the Ulmen replied; "but if my brothers the palefaces will consent to allow me to act, I will undertake to foil the plans of Antinahuel and his companions."

"Speak! speak, chief!" the count exclaimed, vehemently; "explain to us the plan you have formed; these caballeros rely entirely upon you."

"Yes," Don Tadeo replied, "we are listening to you anxiously, chief."

"But," Curumilla resumed, "my brothers must act with caution. I require to be left absolute master."

"You have my word, Ulmen," said Don Gregorio; "we will only act as you command us."

"Good!" said the chief; "let my brothers listen."

And without more delay he detailed to them the plan he had formed, and which, as might be expected, obtained the general assent. Don Tadeo and the count entered enthusiastically into it, promising themselves the happiest results. By the time the last measures were agreed to and all was arranged the night was far advanced, and the four speakers stood in need of some repose. Curumilla in particular, having slept but little for several days, was literally sinking with fatigue. Louis alone appeared to require no repair for his strength. But prudence demanded that a few hours should be given to sleep, and, in spite of the counts remonstrances, they separated.

The young man, forced to submit to the reasons of the experienced men who surrounded him, retired with a very bad grace, promising himself in petto not to let his friends forget the hour fixed upon for their departure.

Louis felt it was impossible to follow their example, and impatience and love—those two tyrants of youth—heated his brain, he ascended to the roof of the palace, and with his eyes fixed upon the lofty mountains, whose dark shadows were thrown across the horizon, he gave all his thoughts to the fair Rosario.

Louis, abandoning himself to delightful thoughts, thus dreamed through the night, and did not think of descending till the stars successively disappeared in the depths of the heavens, and a pale whiteness began to tinge the horizon. In that climate this announced the speedy approach of day.

CHAPTER VIII.

EL CANYON DEL RIO SECO.

At about ten leagues from San Miguel de la Frontera, a miserable town peopled by some twenty or thirty Huiliche shepherds, on the road to Arauca, the land rises rapidly, and suddenly forms an imposing wall of granite, the summit of which is covered with virgin forests of firs and oaks, impenetrable to the sun. A passage of twenty yards at most, is opened by nature through this wall. Its length is more than a mile, forming a crowd of capricious, inextricable windings, which appear constantly to turn back upon themselves. On each side of this formidable defile, the ground, covered with trees and underwood, stage above stage, is capable, in case of need, of offering impregnable intrenchments to those who defend the passage.

This place is named El Canyon del Rio Seco, a name common in America, because not only has vegetation long since covered the face of this wall with an emerald carpet, but it is evident that in remote periods a channel by which the waters of the upper plateaus of the Andes, overflowing, either in consequence of an earthquake or some natural inundation, pour down to the plain—had violently and naturally cut itself a passage to the sea.

Antinahuel, followed closely by the Linda, who wished to see everything for herself, visited the posts, gave short and precise instructions to the Ulmens, and then regained the bivouac he had chosen, and which formed the advanced guard of the ambuscade.

"Now, what are we going to do?" Doña Maria asked.

"Wait," he replied.

And folding himself in his poncho, he laid down on the ground and closed his eyes.

On their side, the Spaniards had set out a little before daybreak. They
