The hair went straight on his shoulders and along his spine. His blood, running cold an instant before from fear, made a great leap in his veins. A picture came in his dark mind: the chase for a deer when the moon had set, the stir of a living thing that broke twigs in the thickets, and the leap he had made. There had been blood, that night,--the wildness and the madness and the exultation of the kill. Of course there had been terror first, but the terror had soon departed and left something lying warm and still in the thickets. It was the same game that walked his trail in front--game that died easily and yet, in a vague way he did not understand, the noblest game of all. It was living flesh, to tear with talon and fang. All his training, all the instincts imbued in him by a thousand generations of cougars who knew this greatest fear, were simply obliterated by the sudden violence of his hunting-madness. He had tasted this blood once, and it could never be forgotten. The flame leaped in his eyes. And then he began the stalk. A cougar, trying to creep silently on its game, does not move quickly. It simply steals, as a serpent steals through the grass. Whisperfoot stalked for a period of five minutes, to learn that the prey was farther away from him at every step. He trotted forward until he came close, and again he stalked. Again he found, after a few minutes of silent creeping through the thickets, that he had lost distance. Evidently this game did not feed slowly, like the deer. It was to be a chase then. Again he trotted within one hundred feet of the girl. Three times more he tried to stalk before he finally gave it up altogether. This game was like the porcupine,--simply to be chased down and taken. As in the case of all animals that hunt their game by overtaking it, there was no longer any occasion for going silently. The thing to do was to come close and spring from the trail behind. Though the fear was mostly gone, the cougar retained enough of that caution that most wild animals exhibit when hunting a new game so that he didn't attempt to strike Snowbird down at once. But as the chase went on, his passion grew upon him. Ever he crept nearer. And at last he sprang full into the thickets beside her. At that instant she had shot for the first time. Because the light had left his eyes before she could find aim, both shots had been clean misses. And terrible as the reports were, he was too engrossed in the chase to be frightened away by mere sound. This was the cry the man-pack always made,--these sudden, startling sounds in the silence. But he felt no pain. He crouched a moment, shivering. Then he bounded on again. The third shot was a miss too: in fact, there had been no chance for a hit. A sound in the darkness is as unreliable a target as can possibly be imagined. And it didn't frighten him as much as the others.
