The note was brief, but to the point. It said:

However, this is a digression. Let us return for the last time to Arthur Robinson's three divisions of youthful humanity. Class A he found extraordinarily dull. They required little instruction and no supervision; in fact, they were self-educators of the most automatic type. Class B were a perpetual weariness to the flesh. They gave no trouble, but their apathy was appalling. However, a certain amount of entertainment could be extracted from studying their

methods of evading work or supplying themselves with refreshment. There was the ingenious device of Master Jobling, for instance. Mr. Robinson noted that this youth was in the habit, during lecture-time, of sitting with his elbows resting on his desk and his chin buried in his hands, his mouth, or a corner thereof, being covered by his fingers. His attitude was one of rapt attention, and his eyes were fixed unwinkingly upon the lecturer. Such virtue, coming from Master Jobling, roused unworthy suspicions in the breast of Arthur Robinson. He observed that although the youth's attitude was one of rigid immobility, his facial muscles were agitated from time to time by a slight convulsive movement. Accordingly, one day, he stepped swiftly across the room, and taking Master Jobling by the hair, demanded an explanation. It was forthcoming immediately, in the form of a long thin indiarubber tube, of the baby's-bottle variety; one end of which was held between Master Jobling's teeth, while the other communicated, via his right sleeve, with a bottle of ginger-beer secreted somewhere in the recesses of his person. From this reservoir he had been refreshing himself from time to time by a process of suction.

Mr. Robinson, who believed in making the punishment fit the crime, purchased a baby's "soother" from the chemist's, and condemned Jobling to put it to its rightful use during every school-hour for the rest of the week. He was only allowed to remove it from his lips in order to answer a question.

Class C, the professional malefactors, Mr. Robinson found extremely attractive. They appeared to possess all the character and quite half the brains of the form. But this is a permanent characteristic of the malefactor, and is most discouraging to the virtuous.

Once, early in his career, Robinson was badly caught. On entering his form-room one winter evening, when darkness had fallen and the gas was ablaze, his eye fell upon the great plate-glass window which filled the south wall of the room. Form-room windows are not usually supplied with blinds, and this window stood black and opaque against the darkness of night. Right in the centre of the glass was a great white star, which radiated out in all directions in a series of splintered cracks.

Mr. Robinson knew well what had happened. Some one had hurled a stone inkpot against the window. Only last week he had had occasion
