One day Mr. Hanbury thoughtlessly came by an unexpected route, and was at the door-handle before Pip realised that he was near. Consequently Pip was thrown heavily on to his back with a contused eye; and after listening throughout the hour to facetious remarks from Ham about Sister Anne and Horatius Cocles, endured the further indignity of being kicked by a select committee of the Lower Shell, who afterwards deposed him from his high office, and appointed Mumford in his stead. Pip's services, however, were speedily requisitioned again, for Mumford proved but a broken reed. He was by nature deliberate in his movements, and the form were more than once taken by surprise owing to their watchman's remissness at the keyhole. His last performance, that which brought Pip back to office, was of such an exceptional nature, and took the fancy of the school to such an extent, that it is to this day preserved among the unwritten archives of Grandwich, bracketed equal with the occasion on which Plumbley minor walked into the French classroom whistling, with a bandbox containing a nest of field-mice under his arm, only to discover, after liberating the mice, that the Head was sitting in the French master's place. Mumford one day stood crouching at his keyhole. All around him surged the Lower Shell, busily employed in obliterating the traces of a brief but sanguinary combat between Jenkins and MacFarlane. The fight had arisen over some small matter of an international character, and after four spirited rounds it was decided that honours so far were equally divided, and that the final round had better be postponed until the interval before dinner. The form accordingly settled down in their places, and with a passing admonition to Mumford to persevere in his vigil, betook themselves to conversation until Ham should be pleased to put in an appearance. As that tyrant had not yet appeared at the far end of the corridor outside, Mumford decided that this was a good opportunity for retiring for a brief moment from his post to his locker, for purposes of refreshment. But fortune was against him. Mr. Hanbury had been out to see the ground-man on some cricket business, and consequently came up to his classroom by that abominable "alternative route." He entered the room quietly, and after walking to his desk was on the point of reprimanding Mumford, whose head was buried in his locker, for being out of his seat, when his words were arrested by the somewhat eccentric behaviour of that remarkable youth. Mumford left his locker, and having thrust a biscuit into his cheek, walked across the room to the door, where he bent down and applied his eye to the keyhole. The form sat spellbound; and Mr. Hanbury was too astonished to break the silence. Meanwhile the infatuated Mumford, having finished his biscuit, proceeded to describe to his classmates the movements of the enemy outside.
