in Thoreau’s Journal:

It is a very beautiful and spotless snow now, it having just ceased falling.  You are struck by its peculiar tractlessness, as if it were a thick white blanket just spread. As it were, each snow-flake lies as it first fell, or there is a regular gradation from the denser bottom up to the surface which is perfectly light, and as it were fringed with the last flakes that fell.
