2. (Charterhouse).—An interval in the middle of each of the three terms of the school year; it was instituted so that there might be no leaving at odd times. It lasts from noon on Saturday to 6.45 P.M. on the following Monday. Formerly Upper School had a going-out Saturday every week, and the Under School one every other week, and leave lasted from noon on Saturday till Sunday evening chapel. Also at Harrow a similar term of leave.

Extra, subs. (Harrow).—1. Extra school on Tuesdays, when those SENT (q.v.) copy out Latin grammar for two hours and a half: an extreme punishment.

2. (Harrow).—An extra day’s BOY (q.v.): given to those who CUT (q.v.) when “on boy.”

3. (Charterhouse).—Extra school: it lasts from 2 to 4 every Wednesday afternoon. The ways of procuring admission to it are various: to neglect a REP (q.v.) or a “construe,” to be late for anything, to make a noise in the cubicles, to come into school in slippers, or any misdemeanour leads to a boy being “down for EXTRA.” The entries are kept in ... The Black Book. Extra school is for offences committed during the first part of the week. There is also Extra drill on Saturdays in Scholars’ Court, which lasts half the time of Extra school, and which is much more disliked, for offences committed between a Thursday and a Saturday.

Extra Drill, subs. (The Leys).—Imposed by way of punishment.
