The attitude of Philip St H. Harrison, of Merevale's House, towards his fellow-man was outwardly one of genial and even sympathetic toleration. Did his form-master intimate that his conduct was not _his_ idea of what Young England's conduct should be, P. St H. Harrison agreed cheerfully with every word he said, warmly approved his intention of laying the matter before the Headmaster, and accepted his punishment with the air of a waiter booking an order for a chump chop and fried potatoes. But the next day there would be a squeaking desk in the form-room, just to show the master that he had not been forgotten. Or, again, did the captain of his side at football speak rudely to him on the subject of kicking the ball through in the scrum, Harrison would smile gently, and at the earliest opportunity tread heavily on the captain's toe. In short, he was a youth who made a practice of taking very good care of himself. Yet he had his failures. The affair of Graham's mackintosh was one of them, and it affords an excellent example of the truth of the proverb that a cobbler should stick to his last. Harrison's _forte_ was diplomacy. When he forsook the arts of the diplomatist for those of the brigand, he naturally went wrong. And the manner of these things was thus. Tony Graham was a prefect in Merevale's, and part of his duties was to look after the dormitory of which Harrison was one of the ornaments. It was a dormitory that required a good deal of keeping in order. Such choice spirits as Braithwaite of the Upper Fourth, and Mace, who was rapidly driving the master of the Lower Fifth into a premature grave, needed a firm hand. Indeed, they generally needed not only a firm hand, but a firm hand grasping a serviceable walking-stick. Add to these Harrison himself, and others of a similar calibre, and it will be seen that Graham's post was no sinecure. It was Harrison's custom to throw off his mask at night with his other garments, and appear in his true character of an abandoned villain, willing to stick at nothing as long as he could do it strictly incog. In this capacity he had come into constant contact with Graham. Even in the dark it is occasionally possible for a prefect to tell where a noise comes from. And if the said prefect has been harassed six days in the week by a noise, and locates it suddenly on the seventh, it is wont to be bad for the producer and patentee of same.
