Bored in their own homes, these young fellows found little or no distraction elsewhere in the city; and as, in the language of that region, "youth must shed its cuticle" they sowed their wild oats at the expense of the town itself.
It was difficult to carry on such operations in open day, lest the perpetrators should be recognized; for the cup of their misdemeanors once filled, they were liable to be arraigned at their next peccadillo before the police courts; and they therefore judiciously selected the night time for the performance of their mischievous pranks.

Thus it was that among the traces of divers lost civilizations, a vestige of the spirit of drollery that characterized the manners of antiquity burst into a final flame.
The young men amused themselves very much as Charles IX.

amused himself with his courtiers, or Henry V.of England and his companions, or as in former times young men were wont to amuse themselves in the provinces.

They called themselves the "Knights of Idleness." During the day these young scamps were youthful saints; they all pretended to extreme quietness; and, in fact, they habitually slept late after the nights on which they had been playing their malicious pranks.
