Yet huge and menacing as he stood, the figure opposed to him was still more formidable. Juan, the _mozo_ overtopped him by nearly half a head, and was as broad or broader in the shoulder. His body, a dull brown in colour, showed smoother than that of his enemy, the muscles not having been brought out by unremitted exercise. Yet under that bulk of flesh there lay no man might tell how much of awful vigour. The loop of the war club would not slip over his great hand. He caught it in his fingers and made the weapon hum about his head, as some forgotten ancestor of his, tall Navajo, or forgotten cave dweller, may have done before the Spaniard came. The weapon seemed to him like a toy, and he cast his eye about for another more commensurate with his strength, but, seeing none, forgot the want, and in the sheer ignorance of fear which made his bravery, began the fight as though altogether careless of its end. White Calf was before his people, whose chief he was by reason of his personal prowess, and with all the vanity of his kind he exulted in this opportunity of displaying his fitness for his place. Yet in him natural bravery had a qualifying caution, which was here obviously well justified. The Mexican made direct assault, rushing on with battle axe poised as though to end it all with one immediate blow. With guard and parry he was more careless than the wild bull of the Plains, which meets his foe in direct impetuous assault. White Calf was not so rash. He stepped quickly back from the attack, and as the _mozo_ plunged forward from the impulse of his unchecked blow, the Indian swept sternly at him with the full force of his extended arm. The caution of the chief, and the luck of a little thing, each in turn prevented the ending of the combat at its outset. Half falling onward, the Mexican slipped upon a tuft of the hard gray grass and went down headlong. A murmur arose from the Indians, who thought at first that their leader's blow had proved fatal. A sharp call from Curly seemed to bring the Mexican to his feet at once. The Indian lost the half moment which was his own. Again the two engaged, White Calf now seeking to disconcert the Mexican, whom he discovered to be less agile than himself. Darting in and out, jumping rapidly from side to side, and uttering the while the sharp staccato of his war call, he passed about the Mexican, half circling and returning, his eye fixed straight upon the other's, and his war club again and again hurtling dangerously close to his opponents head. One shade more of courage, one touch more of the daring necessary to carry him a single foot closer in, and the victory had been with him, for no human skull could have withstood the impact of a pound of flint impelled by an arm so powerful.
