Sometimes the ravines, rivers, cataracts, and sea-arms are passed by huge bridges of the natural rocks, perforated by the sea, or opened by man to render navigation possible. Sometimes bridges miles in length are thrown across a great cataract or immense chasm where the rocks have been relentlessly torn asunder by the lightning and other electrical disturbances.

All the large bridges are covered with houses and gardens, which at a distance seem air-suspended cities, hanging without support over rivers, cataracts, large cities, and aggregations of houses.

Everything conducive to health is attended to: the supply of water to every part of the city is unlimited, and in each house, whether of rich or poor, is a bath, for sea and for fresh water.

We have "violet streams," which run for miles over beds of violets white and blue. The water of these is preserved in tanks erected at the end of the streams, trenches being cut to assist the flow. It has a delicious flavour, and is used for various beverages, but not for culinary purposes, since, when mixed with certain things, it turns black and loses its fragrance.

Trees, plants, and flowers perfume the air with their fragrance; whilst birds of endless variety and richest plumage have their nests in the tall and wide-spreading trees of varied-coloured foliage and fill the air with their music. In the trees are placed artificial nests to entice the birds; these invite others, which build their nests spontaneously. The trees are large, their branches and rich foliage spread themselves in graceful lines to a long distance on every side and afford pleasing shade, their gauzy leaves subduing the light and producing the effect of soft rainbow tints. The trees also emit perfume.

The music of the birds harmonizes with the refreshing sounds of the running waters, cascades, and fountains; and that the effect on the mind of these beautiful harmonies may not be disturbed, the wheels of our chariots as well as the horses' hoofs are bound with a peculiar hide which, besides possessing great toughness and durability, has the property of deadening sound. Thus none but the most agreeable sounds reach the ear, whilst the senses are charmed with aromatic odours and the eye is pleased with beauty of every kind.

Arched galleries and passages through the hills and mountains, partly perforated by the sea or electric fire, and enlarged by the industry of man, have a subdued light and make an impression of another kind, the red light in these perforated roads answering to the red shade of the outer world. These galleries and openings in the rocks are used to shorten distances from one side of a mountain to another.

The whole city is full of animation. The illuminated sky, the variegated plumage of the birds, the moving myriads of human beings, clad in rich costumes of divers colours; horses, elephants, camels, and camelopards, richly caparisoned; carriages gorgeously decorated, the golden domes of the houses, the many-coloured rocks reflecting themselves in the waters and in the brilliant skies, with their own aerial peaks and mountains brilliant and bright with our powerful sunlight—all these combine to produce a gorgeous spectacle. Moreover, the constantly recurring undulations and tortuousness of the ground are so great that it is difficult to proceed for a few minutes without meeting an entire change of scenery, as though one had reached a new city.

At one moment are seen mountain peaks rising almost perpendicularly to the skies in varying height, then a little turn brings the spectator on forests of houses, with ornamental gilded domes and hives of human beings.

Overhanging rock and mountain-forms of varied colours, the skies now scarcely seen, now reflecting their gorgeous tints in the sparkling rivers, cascades, and upheaving masses of water, these and much more form a picture of which words of fire would fail to convey a sufficient idea to those accustomed to the sober, though beautifully subdued tints of your skies.
