The impression of coolness considered so desirable in a garden, is not produced by planting trees too densely and crowding the area with many objects, but by a few masses of foliage judiciously arranged. There must be a total absence of litter and untidiness. Large open spaces partly overgrown with moss and kept cleanly swept should occupy the background, stretches of white sand or gravel being spread in the foreground. Even in the gardens attached to Tea Rooms, where rustic dilapidation is particularly affected, the most scrupulous cleanliness is exacted, an important distinction being always observed between natural decay and litter.
