When several creatures, men or animals, have worked together to overcome something offering resistance and have at last succeeded, there follows often a pause, as though they felt the propriety of paying respect to the adversary who has put up so good a fight. The great tree falls, splitting, cracking, rushing down in leaves to the final, shuddering blow along the ground. Then the foresters are silent, and do not at once sit down. After hours, the deep snowdrift has been cleared and the lorry is ready to take the men home out of the cold. But they stand a while, leaning on their spades and only nodding unsmilingly as the car-drivers go through, waving their thanks.
