They were living in this "selfishness for two" which, while moving mankind from our optic centre, diminishes its defects and makes it appear more beautiful. Satisfied by their mutual affection, everything in nature and humanity sang a perpetual hymn of happiness and love. Often in the evening they walked along the banks of the Seine, dreamily contemplating the effects of light and shade which make the sky of Paris so exquisite at twilight, when the silhouettes of towers and buildings are thrown out against the luminous background in the west. Piles of rose-colored and purple clouds, illuminated by the distant reflection of the sea over which the vanished sun is still shining, give our skies a character of their own, not like that of Naples, bathed in the west by the Mediterranean mirror, but surpassing Venice perhaps, whose illumination is pale and eastern. It might chance that, their steps having led them to the old island of the Cité, they would stroll along the river bank, passing in sight of Notre Dame and the old Châtelet, whose dark outlines might still be seen against the dimly lighted sky. Sometimes, often indeed, enticed by the brilliance of the setting sun and by the fresh green of the country, they went along the _quais_, out beyond the ramparts of the great city, and strayed as far as the solitudes of Boulogne or Billancourt, shut in between the dusky hills of Meudon and Saint-Cloud. They were contemplating Nature; they forgot the noisy city lost behind them; and walking with the same step, forming but one being, they received the same impressions, thought the same thoughts, and by their silence spoke the same language. The stream flowed on at their feet, the noises of the day were dying away, the first stars were peeping out. Icléa liked to tell George their names as they appeared. [Illustration] March and April often offer Paris mild evenings, on which the first warm breezes, forerunners of spring, greet us. Orion's brilliant stars, the dazzling Sirius, the Twins, Castor and Pollux glitter in the immense sky; the Pleiades sink towards the western horizon; but Arcturus and Boötes, shepherd of the celestial flocks, return, and a few hours later white and resplendent Vega rises on the eastern horizon, soon followed by the Milky Way. Arcturus with its golden rays is always the first star to be recognized, from its piercing brilliancy and from its position in the prolongation of the tail of the Great Bear. Sometimes the lunar crescent was hanging in the western sky, and the young girl gazed admiringly, like Ruth by Boaz' side, at "that golden sickle in the field of stars." The stars surround the earth, the earth is in the sky. Spero and his companion realized this, and perhaps no other couple on any other celestial earth lived on more intimate terms than they with the sky and infinity.
