It came without warning. Alcatraz turned with the speed of a whiplash curling and drove straight at the place where his master leaned. Marianne's cry of alarm was not needed. Cordova had already started, but even so he barely escaped. The chestnut on braced legs skidded to the fence, his teeth snapping short inches from the back of his master. His failure maddened Alcatraz. He reminded Marianne of the antics of a cat when in her play with the mouse she tosses her victim a little too far away and wheels to find her prospective meal disappearing down a hole. In exactly similar wise the stallion went around the corral in a whirl of dust, rearing, lashing out with hind legs and striking with fore, catching imaginary things in his teeth and shaking them to pieces. When the fury diminished he began to glide up and down the fence, and there was something so feline in the grace of those long steps and the intentness with which the brute watched Cordova that the girl remembered a new-brought tiger in the zoo. Also, rage had poured him full of such strength that through the dust cloud she caught again glimpses of that first perfection. He came at last to a stop, but he faced his owner with a look of steady hate. The latter returned the gaze with interest, stroking his face and snarling: "Once more, red devil, eh? Once more you miss? Bah! But I, I shall not miss!" It was not as one will talk to a dumb beast, for there was no mistaking the vicious earnestness of Cordova, and now the girl made out that he was caressing a long, white scar which ran from his temple across the cheekbone. Marianne glanced away, embarrassed, as people are when another reveals a dark and hidden portion of his character. "You see?" said Cordova, "you would not be happy in the corral with him, eh?" He rolled a cigarette with smiling lips as he spoke, but all the time his black eyes burned at the chestnut. He seemed to Marianne half child and half old man, and both parts of him were evil now that she could guess the whole story. Cordova campaigned through the country, racing his horse at fairs or for side bets. For two reasons he kept the animal systematically undernourished: one was that he was thereby able to get better odds; the other was that only on a weakened Alcatraz would he trust himself. At this she did not wonder for never had she seen such almost human viciousness of temper in a dumb beast. "As for running, señorita," continued Cordova, "sometimes he does very well--yes, very well. But when he is dull the spurs are nothing to him." He indicated a criss-crossing of scars on the flank of the stallion and Marianne, biting her lips, realized that she must leave at once if she wished to avoid showing her contempt, and her anger.
