Famous quotes containing the word forest:

    A lady with whom I was riding in the forest said to me that the woods always seemed to her to wait, as if the genii who inhabit them suspend their deeds until the wayfarer had passed onward; a thought which poetry has celebrated in the dance of the fairies, which breaks off on the approach of human feet.
    Ralph Waldo Emerson (1803–1882)
