For a full minute Irma was silent as she looked around the vast interior. "I am afraid," she began, "I am afraid that I like it better than St. Peter's. In some way it seems grander."

"You needn't be afraid; older and wiser persons have been heard to say the same thing. A circular building is always impressive, and no interior in the world has finer proportions than this. In some ways it isn't what it once was. The bronze casings of part of the walls one of the popes once stripped off to make cannon for St. Angelo, and in the eighteenth century the beautiful marbles of the attic story above were covered with whitewash, but nothing can destroy the beautiful proportions."

"Don't tell us what they are," urged Aunt Caroline. "It would destroy half the effect to hear what it is in feet and inches."

"There's just one thing Irma ought to know, since she quite scorns a guidebook now. That open aperture in the centre of the dome that looks like a small hole is thirty feet across. It is the only way of lighting the building."

"What do they do when it rains?" asked Irma.

"Why, they let it rain."

"Marion," exclaimed Aunt Caroline, "if you are willing to repeat so aged and infirm a joke as that, you must be feeling better."

Marion glanced toward Irma, but she made no sign as to whether or not she, too, scorned the joke.
