"Probably," said Mr. George; "either with marble, or some other harder stone."
After ascending some distance, Rollo, who went forward, came out upon the landing which led to a range of corridors in the second story, as it were. There were several of these corridors, running side by side, all along the building. On one side, you could pass through arches, and come out to the platforms where the seats had originally been arranged, and where you could look down upon the arena. The seats themselves were all gone, and in their places nothing was left but sloping platforms, all gone to ruin, and covered now with grass, and weeds, and tall bramble bushes. On the other side, you could go out to the outer wall, and look down through immense arched openings, to the ground below.[5]
"Take care, Rollo," said Mr. George; "don't go too near."
"You may go as near as you think it is safe," said Rollo, "and I will keep back an inch from where you go."
"That's right," said Mr. George. "There is great pleasure and satisfaction in going into dangerous places with such a sensible boy as you."
After rambling about among the arches and corridors of the second story for some time, Mr. George and Rollo mounted to a story above. They found ruins of staircases in great numbers, so that there were a great many different places where they could go up. Mr. George allowed Rollo to go about wherever he pleased, knowing that he would keep at a safe distance from all places where there was danger of falling.
From time to time, they met other parties of visitors rambling about the ruins. If these persons were French or German, they generally bowed to Rollo and Mr. George as they passed, and greeted them with a pleasant smile, as if of recognition. If, on the other hand, they were English, they passed directly by, looking straight forward, as if they did not see them at all.
Whenever Rollo came to a new staircase, he wished to ascend it, being seemingly desirous of getting up as high as he could. Mr. George made no objection to this. Indeed, he allowed Rollo to choose the way, and to go where he pleased. He himself followed, walking slowly, in a musing manner, filled, apparently, with wondering admiration, and contemplating the stupendous magnitude of the ruin.
"Uncle George," said Rollo, "if I had my pressing book here, I would gather some of these plants and press them, to carry home."
Mr. George did not answer. He was standing in an advanced position, where he had an uninterrupted survey of the whole interior of the Coliseum; and he was endeavoring to picture to his imagination the scene which must have been presented to view when the vast amphitheatre was filled with spectators.
