AMPHITHEATRE, in gardening, certain dispositions of trees and shrubs on the sides of hilly places, which, if the hill or rising be naturally of a circular figure, always have the best effect. They are to be formed of overgreens, such as hollies, phillereys, laurustines, bays, and such plants, observing to plant the shortest growing trees in the front, and those which will be the tallest behind, such as pines, firs, cedars of Lebanon, &c.
Amphitheatres are also sometimes formed of slopes on the sides of hills, covered only with turf; and, when well kept, they are a great ornament to large gardens.
