1603. Various other sub-arrangements or compartments of this nature may be contrived, as for creeping plants, climbing natives of particular countries, succulents, bulbs, &c.; and the association of plants in this way by strong natural and artificial (alluding to their use) affinities, is well calculated to facilitate both their culture and study. The most complete arrangements of this kind are to be found in the Paris, Dublin Society's, and Glasgow Gardens. The size and shape of these sub-arrangements will, of course, be various, which will add greatly to the interest of the walks. They will, in general, be most advantageously placed round the outskirts of the garden, within the marginal plantation, and should be separated by different sorts of rustic walls, or mounds of rockwork, hedges, thickets of evergreens, and other means. They should all be connected by a walk so constructed that a general spectator may see each scene without being obliged to enter minutely into it; and that, while none can escape the botanist, he may have an easy opportunity of entering minutely into each or any of them.
