"That divides the Upper and Lower Classes," was the prompt reply of Mrs. Pitt, whose stock of knowledge seemed endless. "At one time, a curtain was hung over that bar. Don't you know the story which is told in the 'Spectator Papers,' about the boy who accidentally tore a hole in this curtain? He was a timid little fellow, and was terrified at the thought of the punishment which he felt sure would be his. One of his classmates came to the rescue, saying that he would take the blame upon himself, which he did. It was years later, when the timid boy had become a great judge, that the Civil War broke out, and he and his friend took opposite sides. The kind man who had saved his friend from punishment was a Royalist, and was captured and imprisoned at Exeter, where the other man happened to come at the same time, with the Circuit Court. At the moment when nothing remained but to sentence the 'rebels,' the judge recognized his friend, and by making a very hurried trip to London, he was able to secure a pardon from Cromwell, and thus succeeded in saving the man's life." "That was fine!" said John. "He did pay him back after all, didn't he? I thought he wasn't going to." "Now, we will just look into the Chapter House and the old Jerusalem Chamber, before we go," said Mrs. Pitt, as they left the school. The Chapter House is a beautiful, eight-sided room, dating from the thirteenth century. Here the business of the monastery was always conducted, and at the meetings which came every week, the monks were allowed to speak freely, and to make complaints, if they wished. Here also the monks were punished. "They used to whip them against that central pillar, there," the guard explained. "Here sat the abbot, opposite the door, and the monks sat on benches ranged around the room. Parliament met here for many years, too, its last session in this room being on the day that the great King Hal died." The Chapter House has been restored now, and the windows are of modern stained-glass. In the cases are preserved some valuable documents, the oldest being a grant of land, made by King Offa, in 785. To reach the Jerusalem Chamber, it is necessary to go through a part of the cloisters, and into the court of the Deanery. On one side is the old abbot's refectory, or dining-hall, where the Westminster school-boys now dine. John went boldly up the steps and entered. After a few minutes, he came running out again, exclaiming:
