Quotation by Henry David Thoreau

One wonders if, by its patient study by rocks and sandy capes, it has wrested the whole of her secret from Nature yet. What a rich experience it must have gained, standing on one leg and looking out from its dull eye so long on sunshine and rain, moon and stars! What could it tell of stagnant pools and reeds and dank night-fogs! It would be worth the while to look closely into the eye which has been open and seeing at such hours, and in such solitudes its dull, yellowish, greenish eye. Methinks my own soul must be a bright invisible green.
