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. The cub felt the prod of the life that was in him, and stood up and snarled valiantly by his mother’s side. But she thrust him ignominiously away and behind her. Because of the low-roofed entrance the lynx could not leap in, and when she made a crawling rush of it the she-wolf sprang upon her and pinned her down. The cub saw little of the battle. There was a tremendous snarling and spitting and screeching. The two animals threshed about, the lynx ripping and tearing with her claws and using her teeth as well, while the she-wolf used her teeth alone. Once, the cub sprang in and sank his teeth into the hind leg of the lynx. He clung on, growling savagely. Though he did not know it, by the weight of his body he clogged the action of the leg and thereby saved his mother much damage. A change in the battle crushed him under both their bodies and wrenched loose his hold. The next moment the two mothers separated, and, before they rushed together again, the lynx lashed out at the cub with a huge fore-paw that ripped his shoulder open to the bone and sent him hurtling sidewise against the wall. Then was added to the uproar the cub’s shrill yelp of pain and fright. But the fight lasted so long that he had time to cry himself out and to experience a second burst of courage; and the end of the battle found him again clinging to a hind-leg and furiously growling between his teeth. The lynx was dead. But the she-wolf was very weak and sick. At first she caressed the cub and licked his wounded shoulder; but the blood she had lost had taken with it her strength, and for all of a day and a night she lay by her dead foe’s side, without movement, scarcely breathing. For a week she never left the cave, except for water, and then her movements were slow and painful. At the end of that time the lynx was devoured, while the she-wolf’s wounds had healed sufficiently to permit her to take the meat-trail again.
