Fletcher had barely time to proceed thus far with his speech when an alarming interruption occurred, which put an immediate stop to his further utterance. Nearly at the top of the end wall there had formerly been a ventilator; this, for one reason or another, had been removed, and in the brickwork an open space about a foot square had been left. A hissing noise was suddenly heard outside, and the next moment a stream of water shot through the aperture, and descended in a perfect deluge on the heads of the company.

The fact was that Maxton, ever a reckless young villain, had discovered a hose fixed to one of the mains close to the building, and had immediately seized upon it as an instrument wherewith to wreak vengeance on his companions for having turned him out of the meeting.

Words cannot describe the uproar and confusion which followed. As one man the whole assembly made for the door, but only to find it fastened on the outside. The water flew all over the small building, drenching every one in turn. Some howled, some laughed, and only Bibbs had sufficient presence of mind to creep under the sink, which afforded a certain amount of shelter from the falling flood.

The deluge ceased as suddenly as it had begun, and an instant later the door was flung open, and the figure of a Sixth Form boy was seen barring the exit.

"Now, then," he demanded, "what are you youngsters making this awful row for? I've a jolly good mind to take all your names."

There was a moment's silence. Then Fletcher's voice was heard exclaiming,—

"Oh! it's only old 'Thirsty;' he's all right."

"Here, not so fast," answered the prefect, blocking up the doorway as some boys tried to escape; "what are you chaps doing in here? I thought you'd been told to keep out."

The originator of the meeting pushed his way through the crowd, and taking hold of the big fellow's arm in a familiar manner, said,—

"Oh, it's all right, 'Thirsty,' old chap. We just came inside, and some one squirted water all over us, and that's why we shouted. But we won't do it again."
