But he could detect nothing except a faint sweet lemony scent, rather agreeable than otherwise, which evidently emanated from the bushes budding in the sunshine. He was on the point of resuming his promenade, when a blackbird close by burst into song, and, looking up, Mr. Nilson saw at a distance of perhaps five yards a little tree, in the heart of whose branches the bird was perched. He stood staring curiously at this tree, recognising it for that which he had noticed from his window. It was covered with young blossoms, pink and white, and little bright green leaves both round and spiky; and on all this blossom and these leaves the sunlight glistened. Mr. Nilson smiled; the little tree was so alive and pretty! And instead of passing on, he stayed there smiling at the tree.The Japanese Quince  (1910) by John Galsworthy
