A visit to its source I found to be a most interesting excursion. I was accompanied to it by two friends. We directed our course to the village of Matta Cavallos, passing underneath the double arcade, the superior one having forty-two arches, and which conducts the water from the Therezian hill across a valley close to the city. We called upon Mr. Langsdorffe, the Russian consul, and proceeded from his house up a gradual ascent, covered with almost impervious woods, and, after crossing a deep glen, gained the terrace, which is formed by excavation along the sides of mountains and precipices for nearly four miles. As far as two white pillars, opening into the Orange Valley, a distance of about three miles, the terrace has been recently repaired, and forms of itself a very fine promenade. Upon its inner side the range of aqueduct is erected, which is nearly eight feet high, consisting of two walls, a yard from each other, which space is arched over, and encloses the small stream of water that flows rapidly along a channel hewn out of stone. As far as the pillars it has been recently enlivened by white-washing, and at certain distances small apertures are left, for the purpose of ventilation. In some places, small iron gates are introduced into the wall, to admit of the occasional entrance of persons within it; those gates are locked, and an opening is left at the bottom large enough to receive the arm. There is likewise a bason, cut out of the stone, to supply the passers-by with water, which has rather a peculiar flavour. The eye is delighted with the succession of beautiful scenery which the walk presents, and rambles in undiminished rapture at every point, over the varied and romantic objects which sportive nature has here produced. Precipices above, and accumulated alpines shut in the view to the south and west. Winding glens below, formed by smaller elevations; here and there houses seen almost embosomed in the woody ravines; the valley of Engenho Velho, sprinkled with white houses, which is also the site of the palace of St. Christovao; the city and bay, surrounded with their amphitheatres of mountains; the high soaring masses near the pass to the Tejuca; the towering piles of the Organ range, and others of varied appearance to the right, edging the distant horizon, together form a grand totality, a most animated and animating picture, extending far to the north and east, harmonizing the feelings, and lifting the mind into a profound and pleasing train of wonder and adoration of the all-powerful being who has ordained these noble diversities of nature, over which his creative hand has thrown the graceful and cheerful covering of verdant trees and shrubs, swarming in wild profusion, the hand of man having in few places contributed its aid.
