His principal amusement was roller-skating in the play-room. Dormy had not taken to it in the same way—the greater part of his time was spent with the rabbits and guinea-pigs, where Nat, when he himself had had skating enough, was pretty sure to find him.

I suppose it is with being the eldest sister that it always seems my fate to receive the confidences of the rest of the family, and it was about this time, a fortnight or so after his arrival, that it began to strike me that Nat looked as if he had something on his mind.

"He is sure to tell me what it is, sooner or later," I said to myself. "Probably he has left some small debts behind him at school—only he did not look worried or anxious when he first came home."

The confidence was given. One afternoon Nat followed me into the library, where I was going to write some letters, and said he wanted to speak to me. I put my paper aside and waited.

"Leila," he began, "you must promise not to laugh at me."

This was not what I expected.

"Laugh at you—no, certainly not," I replied, "especially if you are in any trouble. And I have thought you were looking worried, Nat."

"Well, yes," he said, "I don't know if there is anything coming over me—I feel quite well, but—Leila," he broke off, "do you believe in ghosts?"

I started.

"Has any one——" I was beginning rashly, but the boy interrupted me.
