in Thoreau’s Journal:

No sooner has the ice of Walden melted than the wind begins to play in dark ripples over the face of the virgin water. It is affecting to see Nature so tender, however, old, and wearing none of the wrinkles of age. Ice dissolved is the next moment as perfect water as if it had been melted a million years. To see that which was lately so hard and immovable now so soft and impressible. What if our moods could dissolve thus completely? It is like a flush of life on a cheek that was dead. It seems as if it must rejoice in its own newly acquired fluidity, as it affects the beholder with joy. Often the March winds have no chance to ripple its face at all.
