The world is wide. No two days are alike, nor even two hours, neither were there ever two leaves of a tree alike since the creation of all the world; and the genuine productions of art, like those of nature, are all distinct from each other.

The landscape painter must walk in the fields with a humble mind. No arrogant man was ever permitted to see Nature in all her beauty.

Nature is the fountain's head, the source from whence all originality must spring.
