The caravan advanced along the road from Santa Fé to the United States, at a speed unusual under such circumstances. A military system was affected which was imposing, and, indeed, indispensable in these regions, infested not merely by numerous bands of predatory Indians, but also traversed by the pirates of the prairie, more dangerous bandits still, who were driven by their enemies beyond the pale of the law, and who, ambushed at the turnings of roads or in broken rocks, attacked the caravans as they passed, and pitilessly massacred the travellers, after plundering them of all they possessed.
About twenty yards ahead of the caravan rode four men, with their rifles on their thigh, preceded by the guide, who formed the extreme vanguard. Next came the main body, composed of six well-armed peons, watching the mules and baggage, under the immediate orders of the chief of the caravan. Lastly, the capataz rode about thirty paces in the rear, having under his orders four resolute men armed to the teeth.
Thus arranged to face any event, the caravan enjoyed a relative security, for it was not very probable that the white or red pillagers, who were doubtless watching it, would dare to attack in open day seventeen resolute and trained men. At night the horse thieves, who glide silently in the darkness during the sleep of the travellers, and carry off horses and baggage, were more formidable.
Still, either through accident, or the prudential measures employed by the chief of the caravan, since they had left Santa Fé, that is to say for more than a month, the Mexicans had not seen an Indian, or been alarmed. They had journeyed—apparently at least—with as much tranquillity as if, instead of being in the heart of the Rocky Mountains, they were moving along the roads in, the interior of Sonora. This security, however, while augmenting their confidence, had not caused their prudential measures to be neglected; and their chief, whom this unusual leniency on the part of the villains who prowl about these countries alarmed, redoubled his vigilance and precautions to avoid a surprise and a collision with the plunderers.
The discovery, made on the previous day by the guide, of an Indian Crow trail—the most determined thieves in these mountains—added to his apprehensions; for he did not hide from himself that, if he were compelled to fight, in spite of the courage and discipline of his peons, the odds would be against him, when fighting men thoroughly acquainted with the country, and who would only attack him with numbers sufficient to crush his band, however desperate the resistance offered might be.
When he left the camp, the chief of the caravan, suffering perhaps from a gloomy foreboding, spurred his horse and joined the Indian, who, as we said, was marching alone in front, examining the bushes, and apparently performing all the duties of an experienced guide. Curumilla, though he heard the hurried paces of the Mexican's horse, did not turn round, but continued trotting along carelessly on the sorry mule allotted to him for this expedition.
When the chief of the caravan joined him and brought his horse alongside the Indian, instead of speaking to him, he attentively examined him for some minutes, trying to pierce the mask of stoicism spread over the guide's features, and to read his thoughts. But, after a rather lengthened period, the Mexican was constrained to recognize the inutility of his efforts, and to confess to himself the impossibility of guessing the intentions of this man, for whom, in spite of the service he had rendered the caravan, he felt an instinctive aversion, and whom he would like to force, at all risks, to make a frank explanation.
"Indian," he said to him in Spanish, "I wish to speak with you for a few moments on an important subject, so be good enough to put off your usual silence for awhile and answer, like an honest man, the questions I propose asking you."
Curumilla bowed respectfully.
"You engaged with me, at Santa Fé, to lead me, for the sum of four ounces, of which you received one half in advance, to lead me, I say, safely to the frontiers of Upper Mexico. Since you have been in my service I must allow that I have only had reason to praise the prudence in which you have performed your duties; but we are at this moment in the heart of the Rocky Mountains, that is to say, we have reached the most dangerous part of our long journey. Two days ago you lifted the trail of Crow Indians, very formidable enemies of caravans, and I want to consult with you as to the means to employ to foil the snares in which these Indians will try to catch us, and to know what measures you intend to employ to avoid a meeting with them; in a word, I want to know your plan of action."
