in Thoreau’s Journal:

White walls of snow rest on the boughs of trees, in height two or three times their thickness. These white irregular arms give the forest a wintry and picturesque look at a distance. The evergreens, especially the pitch pine, often bear large irregular white burdens, agreeably diversified and loopholed by the interstices of the plumes. But it is only when fresh that this snow on the trees is beautiful. Already, before the storm is over, the surface of the snow in the high woods is full of indentations and hollows where some of this burden has fallen.
