October 27th. -- The ground this morning is white with a thin covering of snow. The foliage has still some variety of hue. The dome of Taconic looks dark, and seems to have no snow on it, though I don't understand how that can be. I saw, a moment ago, on the lake, a very singular spectacle. There is a high north-west wind ruffling the lake s surface, and making it blue, lead-coloured, or bright, in stripes or at intervals; but what I saw was a boiling up of foam, which began at the right bank of the lake, and passed quite across it; and the mist flew before it, like the cloud out of a steam-engine. A fierce and narrow blast of wind must have ploughed the water in a straight line, from side to side of the lake. As fast as it went on, the foam subsided behind it, so that it looked somewhat like a sea-serpent, or other monster, swimming very rapidly.
