This man, as far as it was possible for me to assure myself of it by a hasty glance at him, appeared to belong to the white race; he was about thirty-five or forty years of age; his energetic features, animated by his rapid journey, and by emotion, were handsome, regular, stamped with a certain nobility, and uncommon boldness; his figure was rather below the middle height, but well made; his large shoulders denoted great vigour; he wore the costume of the gauchos of the Banda Oriental, a costume that I had myself adopted--a maroon jacket, a white waistcoat, a sky blue chirapa, white calzoncillos with fringe, under blue cloth trousers, a poncho thrown over the left shoulder, a knife sheathed in the girdle of the chirapa behind his back, a red Phrygian bonnet, slouched over the forehead, and allowing to escape ringlets of thick black hair, which fell in disorder on his shoulders. Suddenly the man threw himself backward, put his knee to the ground, and shouldered his gun. Ten horsemen started up, as if by enchantment, emerging with extreme rapidity from the grass which, up to that time, had concealed them from my view, and precipitated themselves, brandishing their long lances, flourishing their terrible bolas above their heads, and howling with fury, as they looked towards the spot where the gaucho was in ambush. These horsemen were Indiæ bravos. CHAPTER II. THE GAUCHO. The Indians stopped within gunshot of the spot where the gaucho and I were concealed; they appeared to be consulting amongst themselves before commencing the attack. These Indians, thus grouped, formed in the midst of the arid desert, of which they were the veritable kings, a most singular and at the same time a most picturesque tableau, with their noble and animated gestures, their tall and elegant figures, their well-proportioned limbs, and their ferocious appearance. Half-clothed with ponchos in rags, and with pieces of frazada, fastened by leathern strings round their bodies, they brandished their long lances, garnished with iron blades, and ornamented near the points with tufts of ostrich feathers. Their chief, still young, had great black eyes veiled by long black eyelashes; his high cheekbones, surrounded by a mass of sleek and flowing hair, fastened on the forehead by a narrow band of red wool; his mouth, large and furnished with brilliant white teeth, which contrasted with the red hue of his skin, impressed on his physiognomy the stamp of remarkable vigour and intelligence. Although he knew that he was but a little distance from the spot where the gaucho was in ambuscade, and that consequently he was exposed to the danger of being struck by a ball, nevertheless, openly exposing himself to the attack of his enemy, he affected a carelessness and a contempt for the peril by which he was threatened, which was not wanting in grandeur. After a tolerably long discussion, the chief urged his horse forward, and advanced without hesitation towards the rock.
