Little opportunity was given White Fang to see all this. Hardly had the carriage entered the grounds, when he was set upon by a sheep-dog, bright-eyed, sharp-muzzled, righteously indignant and angry. It was between him and the master, cutting him off. White Fang snarled no warning, but his hair bristled as he made his silent and deadly rush. This rush was never completed. He halted with awkward abruptness, with stiff fore-legs bracing himself against his momentum, almost sitting down on his haunches, so desirous was he of avoiding contact with the dog he was in the act of attacking. It was a female, and the law of his kind thrust a barrier between. For him to attack her would require nothing less than a violation of his instinct. But with the sheep-dog it was otherwise. Being a female, she possessed no such instinct. On the other hand, being a sheep-dog, her instinctive fear of the Wild, and especially of the wolf, was unusually keen. White Fang was to her a wolf, the hereditary marauder who had preyed upon her flocks from the time sheep were first herded and guarded by some dim ancestor of hers. And so, as he abandoned his rush at her and braced himself to avoid the contact, she sprang upon him. He snarled involuntarily as he felt her teeth in his shoulder, but beyond this made no offer to hurt her. He backed away, stiff-legged with self-consciousness, and tried to go around her. He dodged this way and that, and curved and turned, but to no purpose. She remained always between him and the way he wanted to go. “Here, Collie!” called the strange man in the carriage. Weedon Scott laughed. “Never mind, father. It is good discipline. White Fang will have to learn many things, and it’s just as well that he begins now. He’ll adjust himself all right.” The carriage drove on, and still Collie blocked White Fang’s way. He tried to outrun her by leaving the drive and circling across the lawn but she ran on the inner and smaller circle, and was always there, facing him with her two rows of gleaming teeth. Back he circled, across the drive to the other lawn, and again she headed him off. The carriage was bearing the master away. White Fang caught glimpses of it disappearing amongst the trees. The situation was desperate. He essayed another circle. She followed, running swiftly. And then, suddenly, he turned upon her. It was his old fighting trick. Shoulder to shoulder, he struck her squarely. Not only was she overthrown. So fast had she been running that she rolled along, now on her back, now on her side, as she struggled to stop, clawing gravel with her feet and crying shrilly her hurt pride and indignation.
