A full stomach conduces to inaction, and the cub lay in the cave, sleeping against his mother’s side. He was aroused by her snarling. Never had he heard her snarl so terribly. Possibly in her whole life it was the most terrible snarl she ever gave. There was reason for it, and none knew it better than she. A lynx’s lair is not despoiled with impunity. In the full glare of the afternoon light, crouching in the entrance of the cave, the cub saw the lynx-mother. The hair rippled up along his back at the sight. Here was fear, and it did not require his instinct to tell him of it. And if sight alone were not sufficient, the cry of rage the intruder gave, beginning with a snarl and rushing abruptly upward into a hoarse screech, was convincing enough in itself.
