in Thoreau’s Journal:

This clear, cold, Novemberish light is inspiriting. Some twigs which are bare, and weeds, begin to glitter with the hoary light. The very edge or outline of a tawny or russet hill has this hoary light on it. Your thoughts sparkle like the water surface and the downy twigs. From the shore you look back on the silver-plated river.

The weeds are dressed in their frost jackets, naked down to their close-fitting downy or flannel shirts. Like athletes they challenge the winter, these bare twigs. This cold refines and condenses us. Our spirits are strong, like that pint of cider in the middle of a frozen barrel.
