The old lady had always been proud of the great rose-tree in her garden, and was fond of telling how it had grown from a cutting she had brought years before from Italy, when she was first married. She and her husband had been travelling back in their carriage from Rome (it was before the time of railways) and on a bad piece of road south of Siena they had broken down, and had been forced to pass the night in a little house by the road-side. The accommodation was wretched of course; she had spent a sleepless night, and rising early had stood, wrapped up, at her window, with the cool air blowing on her face, to watch the dawn. She could still, after all these years, remember the blue mountains with the bright moon above them, and how a far-off town on one of the peaks had gradually grown whiter and whiter, till the moon faded, the mountains were touched with the pink of the rising sun, and suddenly the town was lit as by an illumination, one window after another catching and reflecting the sun’s beam, till at last the whole little city twinkled and sparkled up in the sky like a nest of stars.
