Not a week before—and then the Agency had been officially at peace—a Mexican packer had been shot down by an arrow from some unseen bow, within a thousand yards of the post, in broad daylight. The Indians, caking their bodies with clay, and binding sage or grass upon their heads, could writhe unseen almost within arm's reach. But Felipa was not afraid. Straight for the river bottom she made, passing amid the dump-heaps, where a fire of brush was still smouldering, filling the air with pungent smoke, where old cans and bottles shone in the starlight, and two polecats, pretty white and black little creatures, their bushy tails erect, sniffed with their sharp noses as they walked stupidly along. Their bite meant hydrophobia, but though one came blindly toward her, she barely moved aside. Her skirt brushed it, and it made a low, whining, mean sound.

Down by the river a coyote scudded across her path as she made her way through the willows, and when he was well beyond, rose up on his hind legs and looked after her. At the water's edge she stopped and glanced across to the opposite bank. The restlessness was going, and she meant to return now, before she should be missed—if indeed she were not missed already, as was very probable. Yet still she waited, her hands clasped in front of her, looking down at the stream. Farther out, in the middle, a ripple flashed. But where she stood among the bushes, it was very dark. The water made no sound, there was not a breath of air, yet suddenly there was a murmur, a rustle.

Felipa's revolver was in her hand, and cocked and pointed straight between two eyes that shone out of the blackness. And so, for an appreciable time, she stood. Then a long arm came feeling out; but because she was looking along the sight into the face at the very end of the muzzle, she failed to see it. When it closed fast about her waist, she gave a quick gasp and fired. But the bullet, instead of going straight through the forehead beneath the head band, as she had meant it to do, ploughed down. The grasp on the body relaxed for an instant; the next it had tightened, and a branch had struck the pistol from her hand.

And now it was a struggle of sheer force and agility. She managed to whip out the knife from her belt and to strike time and time again through sinewy flesh, to the bone. The only noise was the dragging of their feet on the sand, the cracking of the willows and the swishing of the blade. It was savage against savage, two vicious, fearless beasts.

The Apache in Felipa was full awake now, awake in the bliss of killing, the frenzy of fight, and awake too, in the instinct which told her how, with a deep-drawn breath, a contraction, a sudden drop and writhing, she would be free of the arms of steel. And she was free, but not to turn and run—to lunge forward, once and again, her breath hissing between her clenched, bared teeth.

The buck fell back before her fury, but she followed him thrusting and slashing. Yet it might not, even then, have ended well for her, had there not come from somewhere overhead the sound most dreaded as an omen of harm by all Apaches—the hoot of an owl. The Indian gave a low cry of dismay and turned and darted in among the bushes.

She stood alone, with the sticky, wet knife in her hand, catching her breath, coming out of the madness. Then she stooped, and pushing the branches aside felt about for her pistol. It lay at the root of a tree, and when she had picked it up and put it back in the holster, there occurred to her for the first time the thought that the shot in the dead stillness must have roused the camp. And now she was sincerely frightened. If she were found here, it would be more than disagreeable for Landor. They must not find her. She started at a swift, long-limbed run, making a wide detour, to avoid the sentries, bending low, and flying silently among the bushes and across the shadowy sands.

She could hear voices confusedly, men hurriedly calling and hallooing as she neared the back of the officers' line and crept into her tent. The door was barely closed when there came a knock, and the voice of the striker asking if she had heard the shot across the river.

"Yes," she said, "I heard it. But I was not frightened. What was it?" He did not know, he said, and she sent him back to the barracks.

Then she lit a lamp and took off her blood-stained gown. There was blood, too, on the knife and its case. She cleaned them as best she could and looked into the chamber of her revolver with a contemplative smile on the lips that less than half an hour before had been curled back from her sharp teeth like those of a fighting wolf. She wondered how badly the buck had been hurt.
