The two sources from which we naturally seek instruction in this matter are, the practice of planters and landscape-gardeners hitherto; and the mode in which trees, shrubs, and flowers are distributed in nature. Till within the last two or three centuries,

All the woods of a place were formed of two or three kinds of trees, planted in rows or in masses, in the geometrical style, which we need not here describe; and the flowers were placed in a compartment near the bouse, walled or hedged round.
