in Thoreau’s Journal:  

Why flee so soon to the theatres, lectures-rooms, and museums of the city? If you will stay here a while, I will promise you strange sights.  You shall walk on water.

All these brooks and rivers and ponds shall be your highway. You shall see the whole earth covered a foot or more deep with purest white crystals in which you slump or over which you glide, and all the trees and stubble glittering in icy armor.
