It was now light twenty-four hours a day; the sun disappeared only briefly near midnight, leaving prolonged, magnificent twilight. Often during this period, the phenomenon of an “ice shower”, caused by the moisture in the air freezing and settling to earth, lent a fairyland atmosphere to the scene. Millions of delicate crystals, frequently thin and needlelike in shape, descended in sparkling beauty through the twilight air.
