If, however, you would see this wonderful gorge to perfection, you must go down into it and find your way to the little path which skirts the stream along a portion of its course. First, descend to the foot of the rock, where the river rushes out of the ravine with a mighty leap, forming a cascade some four hundred feet in height, and you are at once overwhelmed by the grandeur of the scene, and all the poetry in your nature is stirred. From this point you may proceed for some distance along the water-side above the fall. Below you roars the foaming cataract, thundering downward and filling the whole air with its white spray. Above, on either side, are lofty, precipitous rocks, the crests of which are crowned by buildings. This is the town as seen from beneath. No wonder it is called "the City in the Air." As you advance the chasm narrows. You must walk with caution, stepping lightly from rock to rock, till presently you come in sight of a lofty arch, which, spanning the river from side to side, forms a gigantic natural bridge joining the opposite sides of the gorge. Nothing in Nature ever moved me more than the first view of that magnificent arch. With something of the proportions of a cathedral roof it rises above you in massive grandeur, showing beyond, through the opening, a line of sky, and then another cavern-like arch. We could not penetrate farther, and no daylight issued from this second opening. It looked like the mysterious entrance into an underground world, the portal of Hades, and in the excitement produced by the novelty of the scene our surprise could scarcely have been increased had some of the shades from the realms of darkness glided out from amid the gloom, or if Charon's boat had appeared to row us over the ferry. Overhead the hawks and eagles circled round, and with hoarse cries appeared to express their anger at the intrusion of man into these wilds sacred to them. Altogether, the scene is full of strange, awe-inspiring beauty. In the Alps and elsewhere we have, perhaps, beheld grander scenery, but never more impressive. The town of Constantine has not much to commend it as a place of residence. It is neither clean nor well built, while sights and smells the reverse of agreeable are constantly distressing the optic and olfactory nerves. And yet there are perhaps few places where an artist could find more charming subjects for his pencil--curious bits of architecture mingling with Nature in its most beautiful and grandest aspects, fine touches of brilliant color, and quaint winding streets and bazaars,--everywhere the picturesque. Filth and confusion, indeed, but still it is the very confusion that an artist loves.
