There were two study tables, both long and flanked with benches; over the centre of each hung a lamp; beneath this lamp, on either side the table, sat a teacher; the girls were arranged to the right hand and the left; the eldest and most studious nearest the lamps or tropics; the idlers and little ones towards the north and south poles. Monsieur’s habit was politely to hand a chair to some teacher, generally Zélie St. Pierre, the senior mistress; then to take her vacated seat; and thus avail himself of the full beam of Cancer or Capricorn, which, owing to his near sight, he needed.
