A curious appearance was noticeable on various higher parts of the wall: namely, a wart-like eruption, as one would be tempted to call it, being in reality a crop of the soft missiles before mentioned, which, adhering in considerable numbers, and hardening after the usual fashion of papier-mache, formed at last permanent ornaments of the edifice.
The young master's quick eye soon noticed that a particular part of the wall was most favored with these ornamental appendages.

Their position pointed sufficiently clearly to the part of the room they came from.
In fact, there was a nest of young mutineers just there, which must be broken up by a coup d'etat.

This was easily effected by redistributing the seats and arranging the scholars according to classes, so that a mischievous fellow, charged full of the rebellious imponderable, should find himself between two non-conductors, in the shape of small boys of studious habits.

It was managed quietly enough, in such a plausible sort of way that its motive was not thought of.

But its effects were soon felt; and then began a system of correspondence by signs, and the throwing of little scrawls done up in pellets, and announced by preliminary a'h'ms! to call the attention of the distant youth addressed.
