Gradually the horizon widened; scenes and situations in which Archie was still a detached observer, as if looking through a telescope, made themselves visible. He remembered gazing through the bars of the high nursery fire-guard at the joyful glow of the fuel. At the corner of the grate (he remembered this with extreme distinctness), there was a black coal, the edge of which was soft and bubbly. A thin streamer of smoke blew out of it, and from time to time this smoke caught light and flared very satisfactorily. But all that, the joyfulness and the satisfaction, was external to him; it was the coals and the streams of burning gas that were in themselves joyful and satisfactory. That must have been in the winter, and it was in the same winter perhaps that he came home with Blessington and two other children—girls, and larger than himself—whom he grew to believe were his sisters, through a wood of fir-trees between the trunks of which shone a round red ball that resembled the coals in the nursery-grate. He knew—perhaps Blessington, perhaps a sister, perhaps his mother had told him—that it was Christmas Eve, and he saw that when Blessington spoke to him she steamed delightfully at the mouth, as if there had been a hot bath just inside her lips. At her suggestion he found he could do it, too, and his sisters also; whereafter they played hot-baths all the way home. But of the Christmas Day that followed he had no recollection whatever.
His observation became a little less detached; he began to form in his mind an explorer's map of the places where these phenomena occurred, to be dimly aware that he was taking some sort of part in them, and was not a mere spectator, and one summer evening he definitely knew that the day-nursery and the night-nursery and the room beyond where his sisters slept were all part of the red-brick house which he and others inhabited, just as, according to Blessington,
