"There," said the tall Scotchman who attended them about the place, "is the room where Rizzio was murdered, in the presence of Mary." They were told that a certain stain in the floor was the blood of the hapless man. [Illustration: MARY STUART.] "We must ask Master Lewis to tell us the whole story," said Wyllys. They next visited St. Giles, the scene of the preaching of Knox, the Martyrs' Monument, and Knox's grave. "We must have an evening meeting of the Club in Edinburgh," said Wyllys Wynn, when the party with Master Lewis were at tea. "To-night?" asked Frank. "I would wait until after we have been to Abbotsford," said Master Lewis. "Then I would have a meeting in the parlor, and let each one tell some story associated with the most interesting object he has seen." [Illustration: MURDER OF RIZZIO.] The next day Master Lewis and the tourists, except George and Leander, who preferred remaining in the city, took the train for Melrose, stopped at Melrose Station, and rode to Abbotsford, the reputed haunt of Thomas the Rhymer, and the residence of Walter Scott. They were met at the entrance of the gray mansion by a tall Scotchman, and were taken from the magnificent entrance hall, about forty feet in length, to the dining-room, which has a wonderful black-oak roof, and is the place where Sir Walter died. Gazing from the window on the beautiful landscape for the last time, he said to Lockhart, "Bring me a book." "What book?" "There is but one book." They were next shown the library, a repository of some twenty thousand books and of presents from most eminent persons, among them a silver urn from Lord Byron and two arm-chairs from the Pope. Our tourists next visited the ruin of Melrose Abbey, and found it less interesting than its historic associations. Late evening found them again in Edinburgh. "What time of the evening do you think it is?" asked Master Lewis of the boys as they entered the hotel. "Seven o'clock," said Tommy Toby. "After nine o'clock," said Master Lewis. The Castle still stood in the damask light of the twilight, like a dark picture on an illuminated curtain. "The summer days in these Northern regions are as long as they are beautiful," said Master Lewis. CHAPTER VI. STORY TELLING IN EDINBURGH. Story of Queen Mary and Rizzio.--Story of the Black Douglas.--Story of a Glasgow Factory Boy.--The Castle by Moonlight. The following day was to be the last the party were to spend in the beautiful city of Edinburgh. In the evening the Class met as by appointment, and, at the suggestion of Wyllys Wynn, Master Lewis was asked to conduct the exercises of the section of the Club. "I thank you," he said, "for this kind confidence, and I think we may congratulate ourselves on the success of our journey thus far. I will begin our conversation by asking Wyllys Wynn what is the most interesting place he has seen in Scotland."
