He forded the Rio Bermejo, and speedily disappeared amongst the tall grasses that bordered the opposite bank.
As soon as the unknown had assured himself of the lepero's departure, he began to calculate the time by the enormously lengthened shadows of the trees; and, after looking about him attentively, gave a whistle, sharp and prolonged, which, although restrained, was nevertheless repeated by all the echoes of the river, so powerful was its tone.
At the end of a few seconds a distant neighing made itself audible, followed almost immediately after by the sound of precipitate galloping, resembling the rolling of distant thunder.
Little by little the sound grew nearer, the branches crashed, the underwood was violently dashed aside, and the unknown's mustang made his appearance on the skirt of a wood at a little distance.
When there, the noble animal paused, snuffed the air vigorously, turning his head and neck in all directions; then starting off, with a thousand capers he made the best of his way, till he halted before his master, and gazed upon him with eyes full of intelligence.
The latter patted him gently, talking to him in a caressing voice; then, having made quite sure that the lepero was gone, and that he was assuredly alone, he readjusted the trappings of his horse, which had become slightly disordered, vaulted into the saddle and in his turn departed.
But instead of continuing to follow the course of the Rio Bermejo, he turned his back upon it, and rode in the direction of the mountains.
The bearing of the unknown had undergone a complete change; it was no longer the man whom we formerly presented to our readers, half asleep, swaying in the saddle, and leaving his horse to wander at leisure. No; now he held himself firm and upright on his mustang, with limbs closely pressing its flanks; his face was overcast with dark shades of thought; his glances wandered about as if they would pierce the mysteries of the thick forest with which he was surrounded; with head slightly bent forward, he listened with strained attention to the most trifling noise; and his rifle, placed across the saddlebow, had the lock exactly under his right hand, in such a fashion that he could fire instantaneously, if circumstances required.
One might have said, so suddenly had the man changed, that the strange scene to which we have just introduced our reader was for him only one of those thousand accidents, without consequences, to which his desert life exposed him, but that now he was preparing to battle with dangers which might really prove serious.
