"If you find fairyland, it ought to be while the heather moon shines," I told him. "But I shan't have much time to help you look for it, because in five days you'll be leaving me with mother, and travelling on alone. You must search for the key to the rainbow wherever you go; because, you know, it might be anywhere, and the light of the heather moon would show it gleaming in the grass, or under a flower, or even in the middle of the road before your eyes."

He looked at me in an odd, almost wistful way, and I couldn't look away from him, though I wanted to, for it was as if he were reading my inmost Me—using my eyes for windows, of which I couldn't draw the curtains.

"It was the knight who opened it!" I interrupted him. "But did you really go near to the border?"

"The border of fairyland."

"Oh! I meant Scotland. But, after all, to me it seems much the same thing. Doesn't it to you?"

"I haven't thought of it so for a good many years," he said. "Yet it might be——"
