The first rhythm that they became used to was the slow swing from dawn to quick dusk. They accepted the pleasures of morning, the bright sun, the whelming sea and sweet air, as a time when play was good and life so full that hope was not necessary and therefore forgotten. Toward noon, as the floods of light fell more nearly to the perpendicular, the stark colors of the morning were smoothed in pearl and opalescence; and the heat--as though the impending sun's height gave it momentum--became a blow that they ducked, running to the shade and lying there, perhaps even sleeping.
