did not ask for any
thing. He did not speak a word."

"And what did he do after you gave him the cake?" asked Rosie.

"He looked up a moment to see if I was going to give him any more," said
Rollo, "and then he walked away."

CHAPTER XI.

AN EXCURSION.

"Uncle George," said Rollo one morning, while he and Mr. George were
eating their breakfast in the dining room, or, as they call it in
Europe, the _salle a manger_, of the hotel, "how much longer are you
going to be in studying out those things in the museum?"

"Why?" asked Mr. George. "Does your comfort or enjoyment depend in any
way on the decision of that question?"

"Only we want you to go about with us, somewhere," said Rollo.

"Why, you don't need me to go about with you," said Mr. George.
"Contrive some sort of excursion yourself, and take the ladies out and
amuse them. You might take them out to see Pozzuoli and the Solfatara.
Besides, you would be doing me a great service if you would go."

"How?" asked Rollo.

"Why, I shall want to go by and by myself," said Mr. George, "and I
don't want to have any trouble in finding the way. But you like finding

Serapis, half under water, and the great amphitheatre, and the
Solfatara, which is the crater of a volcano almost extinct. All these
things lie pretty near together along the shores of the bay to the
westward of Naples, and you can go and see them in one afternoon, they
say. If you go first, you will find out all about the excursion, and
what we do about guides and custodians at the different places; and
then, when I get ready, you can go again and take me, and I shall not
have any trouble about it."

"Just give me a list of all those places," said Rollo, eagerly.

As he spoke he handed Mr. George a pencil and a piece of paper, which he
took out of his pocket. Mr. George wrote down the list, and Rollo,
taking it, went up to Mrs. Gray's room.

Rollo proposed the plan to Mrs. Gray of making the excursion which Mr.
George had indicated, and she was very much pleased with it.

"We'll study it all out in the guide books this evening," said Rollo,
"and then to-morrow we will go."

Mrs. Gray approved of this plan, and so Rol
