Thoreau writes in his journal:
The change from foul weather to  fair, from dark, sluggish hours to serene, elastic ones,  is a memorable crisis which all things proclaim. The change from foulness to serenity is instantaneous. Suddenly an influx of light, though it was late, filled my  room. I looked out and saw that the pond was already calm and full of hope as on a summer evening, though  the ice was dissolved but yesterday. There seemed to  be some intelligence in the pond which responded to the unseen serenity in a distant horizon. I heard a robin  in the distance, the first I had heard this spring, repeating the assurance. The green pitch [pine] suddenly looked brighter and more erect, as if now entirely washed and cleansed by the rain. I knew it would not rain any more. A serene summer-evening sky seemed  darkly reflected in the pond, though the clear sky was nowhere visible overhead. It was no longer the end of a season, but the beginning. (Journal, 1:400)
