in Thoreau’s Journal:
Loring’s Pond beautifully frozen. (This is the first skating.)
So polished the surface, I took many parts of it for water. It was waved or watered with a slight dust, nevertheless. Cracked into large squares, like the faces of a reflector, it was so exquisitely polished that the sky and dun-colored scudding clouds, with mother-o’-pearl tints, were reflected in it as in the calmest water. I slid over it with a little misgiving, mistaking the ice before me for water. Still the ruby-crowned birds about.
