“Every night,” Regie promised, solemnly.

“Not every night, Rex,” said Mr. Fairfax. “That will not be necessary, because you see we shall spend a week in London, and another whole week in Berlin, and two weeks perhaps in Paris.”

“Shall you?” asked Regie, ruefully.

“Why, to be sure; have you any objections, Rex?”

“Oh, I thought you'd keep going and going until you got back again. I shall not like to think of you as stopping so long anywhere.”

“We shall come home just as soon,” laughed Mr. Fairfax, giving that little adopted boy of his the most genuine sort of a fatherly hug.

All too soon it was nine o'clock, and time for the children to go to bed.

Mrs. Fairfax went up herself with Regie. Sister Julia had been up before her and lighted the candle, and laid Regie's night-dress out on the bed.

“You will try not to give Mrs. Murray any trouble, won't you, dear?” said Mrs. Fairfax, helping Regie to undress.

“Yes, I will, Mamma Fairfax,” Regie answered, with a little quiver in his voice.
