The Mystery of Cleverly (Esprios Classics) - George Barton - Bog

"It was a custom which, originating down east, had spread to the little town in New Jersey. The method was quite simple. After the Christmas holidays the big boys put their heads together and decided on a plan of campaign. When all of the details had been arranged, it was decided to put them into execution at the first regular session of the new year. The forenoon passed off as quietly as any other day, the boys looking very sober and extremely attentive to their studies, and keeping unusual order. The moment the schoolmaster left the house for his dinner and the smaller children were started homeward, the doors and windows were suddenly and securely locked, and the older pupils proceeded to spend the afternoon in play and hilarity."
