Even the horse-cars and omnibuses were scantily patronized, while the poor drivers, muffled to their eyebrows in fur coats and comforters, seemed like dark, grim specters, devoid of life and motion, save for the breath that issued from their mouths and nostrils, and, congealing, formed in frozen globules among their beards.
