CHAPTER XVIII. THE POLAR NIGHT, 'HE long night was ushered in by a violent storm. The cold r^ was perhaps a little less severe, but the air was very damp, and, in spite of every precaution, the humidity penetrated into the house, and the condensers, which were emptied every morn- ing, contained several pounds of ice.
