in Thoreau’s Journal:
Go out at 9 AM to see the glaze. It is already half fallen, melting off. The dripping trees and wet falling ice will wet you through like rain in the woods. It is a lively sound, a busy tinkling, the incessant brattling and from time to time rushing, crashing sound of this falling ice, and trees suddenly erecting themselves when relieved of their loads. It is now perfect only on the north sides of woods which the sun has not touched or affected. Looking at a dripping tree between you and the sun, you may see here or there one or another rainbow color, a small brilliant point of light.
