"Five or ten years," said Mr. George.

"O uncle George!" exclaimed Rollo; "I have seen as much of them as I want to see already."

"You have not seen one of them yet," said Mr. George.

"Not seen one of them!" repeated Rollo.

"No, not one of them," replied Mr. George.

"I don't know what you mean by that," said Rollo.

"I'll show you what I mean some time or other," said Mr. George, "when you are in one of the galleries with me."

"I should like to have you," said Rollo; "but now I really want to know when you are going to be ready to go on towards Naples. I'd rather see Mount Vesuvius than all the paintings in the world, especially if there is a good blazing eruption coming out of it, and plenty of red-hot stones."

"The first question to be settled," said Mr. George, "is, how we shall go."
