Such bridges are not only useful, in so far as they serve for the purpose of communication, but they have value as objects enriching the landscape, more especially when seen from the walks which may be at a lower level. It is im- proper to cover the roof of such bridges with gravel, as it is both out of character, and it lays an unnecessary load upon them, which their construction is not suited to carry. § 5.—RILLS, RIVULETS, AND CASCADES. In this style, artificial rills, rivulets, and cascades, may be introduced: if they exist naturally, even to a limited extent, they may be extended; or if the situation is naturally favourable to their introduc- tion artificially, happy effects may be produced; but they must be natural to the scene—and such scenes, says the author of "Observations on Modern Gardening," "commonly require every accompaniment which can be procured for them. Mere rocks, unless they are peculiarly adapted to certain impressions, may surprise, but can hardly please.
