At first Harry could not understand how a religious woman like Mrs. Bickersteth could countenance and keep such a flagrant bully, since what he heard at odd times must be heard morning after morning by some member of the household. The explanation dawned upon him by degrees. Scrafton had been there so many years that he had gained an almost complete ascendency over every adult in the establishment. The one instance in which Harry knew Mrs. Bickersteth to stand firm was that of his own continuance in the school. The one member of the Bickersteth family whom he ever heard breathe a syllable against Scrafton was the good-hearted, golden-haired Baby. Harry once met her face to face on the stairs when a roaring and a thumping and a sobbing were going on behind that terrible closed door. Harry looked at her grimly. Miss Bickersteth reddened to the roots of her yellow hair. "It does sound dreadful," she admitted. "But--but Mr. Scrafton's kinder than you think; he sounds worse than he is. And he teaches them so well; and--and he has been here so many years!" Harry thought there was a catch in her voice as she brushed past him; for one thump had sounded louder than the rest; and first a slate had fallen, and then a boy. Indeed it was a common thing to hear the boys whispering that so-and-so had been knocked down that day. But the fiend was clever enough to keep his fist for their bodies, his flat hand for their faces; the wretched little victims were never actually disfigured. That he was a clever teacher Harry did not doubt. With quick receptive material he was probably something more, and there were one or two boys whom that baleful face, that ready hand, and that roaring voice did not instantly daze and stupefy, and who were consequently getting on remarkably well under Mr. Scrafton. With his repulsive personality, and his more repulsive practices, the man had yet a touch of genius. He wrote the boys' names in their Latin Grammars in the most perfect and beautiful copperplate hand that Harry had ever seen. And those quicker boys would show him sums worked out by no recognised rule, but with half the figures expended in the "key": for Scrafton had a shorter and better rule of his own for every rule in arithmetic.
