Art can never match the luxury and superfluity of Nature.

Context

“The trees made an admirable fence to the landscape, skirting the horizon on every side. The single trees and the groves left standing on the interval appeared naturally disposed, though the farmer had consulted only his convenience, for he too falls into the scheme of Nature. Art can never match the luxury and superfluity of Nature. In the former all is seen; it cannot afford concealed wealth, and is niggardly in comparison; but Nature, even when she is scant and thin outwardly, satisfies us still by the assurance of a certain generosity at the roots.” source
