No dew; no dewy cobwebs. The sky looks mist-like, not clear blue. An aurora fading into a general saffron color. At length the redness travels over, partly from east to west, before sunrise, and there is little color in the east. There is no name for the evening red corresponding to aurora. It is the blushing foam about the prow of the sun’s boat, and at eve the same in its wake.
