Hithertq, we have supposed only fibrous-rooted herbaceous plants to be planted in the beds; but, if bulbs are mixed with these, the bulbs may be allowed to remain after the fibrous-rooted flowers have been removed: because they will thrive with much less light and air than the fibrous-rooted plants; and because they spring up and grow with great rapidity; flower early in the season, before the leaves of the deciduous trees have expanded so as to shade them; and, when they have done flowering, they fade speedily, and their foliage, when removed, leaves no trace of the plants behind, and, consequently, causes no unsightliness on the surface of the ground throughout the summer. Besides, there arc certain kinds of bulbs, such as the scillas, some kinds of hyacinths, the snowdrop, and the narcissuses, which thrive better under a slight degree of shade than when fully exposed to the atmosphere. Bulbs, therefore, may be planted among groups of trees and shrubs, and in close shady places in suburban gardens, where fibrous-rooted flowering plants are inadmissible.

In the borders under the side fences, in this design, flowers of all kinds may be cultivated, during the entire existence of the garden; because, being unmixed with shrubs, except those which are trained against the fences, they would be freely exposed to the light and air, and might be taken up and replanted, and the soil renewed at pleasure.
