Had there been food, love-making and fighting would have gone on apace, and the pack-formation would have been broken up. But the situation of the pack was desperate. It was lean with long-standing hunger. It ran below its ordinary speed. At the rear limped the weak members, the very young and the very old. At the front were the strongest. Yet all were more like skeletons than full-bodied wolves. Nevertheless, with the exception of the ones that limped, the movements of the animals were effortless and tireless. Their stringy muscles seemed founts of inexhaustible energy. Behind every steel-like contraction of a muscle, lay another steel-like contraction, and another, and another, apparently without end. They ran many miles that day. They ran through the night. And the next day found them still running. They were running over the surface of a world frozen and dead. No life stirred. They alone moved through the vast inertness. They alone were alive, and they sought for other things that were alive in order that they might devour them and continue to live. They crossed low divides and ranged a dozen small streams in a lower-lying country before their quest was rewarded. Then they came upon moose. It was a big bull they first found. Here was meat and life, and it was guarded by no mysterious fires nor flying missiles of flame. Splay hoofs and palmated antlers they knew, and they flung their customary patience and caution to the wind. It was a brief fight and fierce. The big bull was beset on every side. He ripped them open or split their skulls with shrewdly driven blows of his great hoofs. He crushed them and broke them on his large horns. He stamped them into the snow under him in the wallowing struggle. But he was foredoomed, and he went down with the she-wolf tearing savagely at his throat, and with other teeth fixed everywhere upon him, devouring him alive, before ever his last struggles ceased or his last damage had been wrought. There was food in plenty. The bull weighed over eight hundred pounds—fully twenty pounds of meat per mouth for the forty-odd wolves of the pack. But if they could fast prodigiously, they could feed prodigiously, and soon a few scattered bones were all that remained of the splendid live brute that had faced the pack a few hours before. There was now much resting and sleeping. With full stomachs, bickering and quarrelling began among the younger males, and this continued through the few days that followed before the breaking-up of the pack. The famine was over. The wolves were now in the country of game, and though they still hunted in pack, they hunted more cautiously, cutting out heavy cows or crippled old bulls from the small moose-herds they ran across.
