The whole room blazed with light — and not with light alone but with a thousand colours, with all the glories of some painted window; and upon the walls of his room and on the familiar furniture, the glow flamed back and seemed to flow again to its source, the little wooden box. For there upon a bed of soft wool lay the most splendid jewel, — a jewel such as Dyson had never dreamed of, and within it shone the blue of far skies, and the green of the sea by the shore, and the red of the ruby, and the deep violet rays, and in the middle of all it seemed aflame as if a fountain of fire rose up, and fell, and rose again with sparks like stars for drops.
