half past six o'clock
It grew colder and colder as the night advanced , and the gale increased . At three o'clock in the morning the centigrade thermometer was at eighteen degrees below . The cooker was lighted again , and until six o'clock the party huddled wretchedly about it , dozing and waking , shivering continually . Breakfast at half past six o'clock ; under way again an hour later . There was no change in the nature of the ice . Ridge succeeded ridge , hummock followed upon hummock . The wind was going down , but the snow still fell as fine and bewildering as ever .
