in Thoreau’s Journal:

To-day the trees are white with snow—I mean their stems & branches and have the true wintry look-on the storm-side—not till this has the winter come to the forest.

They look like the small frost work in the path & on the windows now—. especially the oak woods at a distance, & you see better the form which their branches take. That is a picture of winter & now you may put a cottage under them and roof it with snow drifts.— & let the smoke curl up amide the boughs in the morning.
