But there was one trial in White Fang’s life—Collie. She never gave him a moment’s peace. She was not so amenable to the law as he. She defied all efforts of the master to make her become friends with White Fang. Ever in his ears was sounding her sharp and nervous snarl. She had never forgiven him the chicken-killing episode, and persistently held to the belief that his intentions were bad. She found him guilty before the act, and treated him accordingly. She became a pest to him, like a policeman following him around the stable and the hounds, and, if he even so much as glanced curiously at a pigeon or chicken, bursting into an outcry of indignation and wrath. His favourite way of ignoring her was to lie down, with his head on his fore-paws, and pretend sleep. This always dumfounded and silenced her. With the exception of Collie, all things went well with White Fang. He had learned control and poise, and he knew the law. He achieved a staidness, and calmness, and philosophic tolerance. He no longer lived in a hostile environment. Danger and hurt and death did not lurk everywhere about him. In time, the unknown, as a thing of terror and menace ever impending, faded away. Life was soft and easy. It flowed along smoothly, and neither fear nor foe lurked by the way. He missed the snow without being aware of it. “An unduly long summer,” would have been his thought had he thought about it; as it was, he merely missed the snow in a vague, subconscious way. In the same fashion, especially in the heat of summer when he suffered from the sun, he experienced faint longings for the Northland. Their only effect upon him, however, was to make him uneasy and restless without his knowing what was the matter. White Fang had never been very demonstrative. Beyond his snuggling and the throwing of a crooning note into his love-growl, he had no way of expressing his love. Yet it was given him to discover a third way. He had always been susceptible to the laughter of the gods. Laughter had affected him with madness, made him frantic with rage. But he did not have it in him to be angry with the love-master, and when that god elected to laugh at him in a good-natured, bantering way, he was nonplussed. He could feel the pricking and stinging of the old anger as it strove to rise up in him, but it strove against love. He could not be angry; yet he had to do something. At first he was dignified, and the master laughed the harder. Then he tried to be more dignified, and the master laughed harder than before. In the end, the master laughed him out of his dignity. His jaws slightly parted, his lips lifted a little, and a quizzical expression that was more love than humour came into his eyes. He had learned to laugh.
