Nature teaches more than she preaches. There are no sermons in stones. It is easier to get a spark out of a stone than a moral.
Nature will bear the closest inspection. She invites us to lay our eye level with her smallest leaf, and take an insect view of its plain.
Henry David Thoreau
Nature, to be commanded, must be obeyed.
Never measure the height of a mountain until you have reached the top. Then you will see how low it was.
Nothing is more memorable than a smell. One scent can be unexpected, momentary and fleeting, yet conjure up a childhood summer beside a lake in the mountains.
