The sun had disappeared behind the snowy peaks of the Cordilleras; but the beautiful Peruvian sky long retains, through the transparent veil of night, the reflection of his rays; the atmosphere is impregnated with a refreshing coolness, which in these burning latitudes affords freedom of breath; it is the hour in which one can live a European life, and seek without on the verandas some cooling gentle zephyr; it seems as if a metallic roof was then interposed between the sun and the earth, which, retaining the heat and suffering only the light to pass, offers beneath its shelter a reparative repose.
