“Do, too,” whispered Nan, with a defiant shake of her curls; “but please don't interrupt. Go on, Rex.” Rex did not mind these interruptions in the least, as they gave him a chance to look ahead a little.

“'It is ten years,'” he went on, reading slowly, “'since Papa Fairfax and I were here before, and we hardly know this London in the sunshine, for the old London of fog and rain, since we are having wonderfully clear weather. I shall have to wait till we reach home to tell you all about the sights of London. When you are older I shall hope to visit with you all the places where Papa Fairfax and I have been this morning,—Westminster Abbey, and St. Paul's, and the Tower. How you will enjoy the Tower, but in a sad sort of way, because so many sorrowful things have happened there. Last evening we strolled in for a while to see Madame Tussaud's wax figures, naturally looking rather more grimy and dusty than they did ten years ago.

“'And now, Rex, I have several other letters to send off by this same steamer, so this must do for the present. Do not forget to write once a week surely, either to Papa Fairfax or to me.

“'Yours lovingly,

“'Mamma Fairfax.

“That's a nice letter,” said Regie, gazing rather wistfully out to sea.

“Very nice,” said Nan, “but you don't want to go, do you?”

Poor little Nan was blessed with a lively imagination.

I say “poor Nan,” for these lively imaginations play such sorry tricks upon the little folk and big folk who happen to possess them. Nan had but to catch a glimpse of the wistful look in Regie's eyes straightway to make up her mind that he was unhappy and lonely, and would gladly leave them all if he could.

“No, I don't want to go exactly,” answered Rex; “but I guess you'd feel a little queer sometimes if that great ocean were between you and your father and mother.”
