in Thoreau’s Journal:
….Now, as after a freshet in cold weather, the ice which had formed around and frozen to the trees and bushes along the shore, settling, draws them down to the ground or water, after breaking them extensively. It reminds you of an alligator or other evil genius of the river pulling the trees and bushes, which had come to drink, into the water. If a maple or alder is unfortunate enough to slip its lower limbs into the freshet, dallying with it, their fate is sealed, for the water freezing that night takes fast hold of them like a vise, and when the water runs out from beneath an irresistible weight brings them down to the ground and holds them there. Only the spring will soften the heart of the relentless monster when commonly it is too late.
