“You’ll have to,” said practical Flo, “unless you leave one at Naples or Gibraltar.”

“I wish you were going to Naples with us.”

“I wish so too, Patty; but mother has written us to come home, and we really must go. But it has been a lovely pleasure trip with you, and I’m sure we’ll meet again.”

“Of course we shall. You surely must come to New York. Snippy can bring you, can’t she?”

“Yes, indeed; Snippy could take me to the North Pole, if we decided to go.”

“Well, see that she brings you to New York first. And now good-by, Flo, dearie. Write to me soon and often. Good-by, Snippy.”

“Good-by, Miss Patty.”

And then everybody said good-by to everybody else, and the travellers took the train, and Patty waved to Flo from the window, and called good-by again, and then they started, and the Fairfields were once more by themselves.

“You’ll be dull, Patsy,” said her father, “with only your own relatives to entertain you.”
