Hadn't we better chuck a stone." Heathcote detached a piece of plaster from the gutter, and pitched it neatly down within an inch of the head of the unsuspecting Pauncefote.
That hero started, and looked first at the stone, then at the sky.
Finally his eyes met Georgie's triumphant face beaming over the parapet, side by side with the rosy countenance of Coote.
It was enough.

In another two minutes the Den knew what was going on, and Georgie and Coote were the heroes of the hour.
Moved by a desire to afford their spectators an entertainment worthy of their applause, they proceeded to make the round of the Quadrangle at a smart, though not always steady, pace; for their attention was so much divided between the gutter before them and the upturned faces below them, that they were once or twice decidedly close on the heels of the luckless Fitch.
Once, when they came to a comparatively broad landing, they varied the entertainment by swarming a little way up the tiles and sliding gracefully down again, regardless of tailors' bills; and when the spectators got tired of that, they treated them to a little horse-play by pelting them with bits of plaster, and finally with Coote's hat.
Even the highest class of entertainment cannot thrill for ever, and after a quarter of an hour of this edifying exhibition, the Den found they had had enough of it, and began to saunter off, much to the amazement of the two performers.
"May as well cut down," said Heathcote, when at length the Quad was deserted, and nothing seemed likely to be gained by remaining.
Coote was quite ready to obey.

He had enjoyed his outing pretty well, but was rather tired of standing with one foot in front of the other, and keeping his eyes on Georgie.
He was nearest to the trap-door and had already crouched through it when Heathcote, perceiving that one of the Den had come back for another look, decided, in the kindness of his heart, to take one last turn round before retiring.
He had accomplished half his journey, and was glancing down rather anxiously to see if the boy was enjoying it, when a second-floor window on the opposite side suddenly opened and Mansfield looked out.
This apparition nearly sent Georgie headlong over the parapet.

He saved himself by dropping on his hands and knees.

He wasn't sure whether the Captain had seen him or not.
