There are three principal roads leading from this city, none of which are adapted to the use of a carriage for more than six or seven miles. The first, leading to the southward, after passing the public gardens and the Lapa, proceeds, for a short distance, along the banks of the bay, commanding a view of its entrance, which is soon interrupted by the Gloria Hill, behind which the road passes, and continues in a parallel line with the Pria Flemingo, which is adorned with several neat houses, many of them occupied by English merchants. The Hon. Mr. Thornton had taken up a temporary residence in one of them. After crossing a small bridge at the Cateta, the road conducts, for about a mile and a half, betwixt luxuriant and verdant hedges, to the beach or Pria of Bota-fogo, which is a fine bay, shut in by picturesque promontories and headlands, leaving only a narrow channel for the ingress and egress of its waters. This beach is edged with some of the neatest and most elegant houses in the vicinity of Rio de Janeiro, many of them occupied by fidalgos, and others by English merchants; one of which, in the possession of Mr. Harrison, exhibits all the beauty, elegance, and comfort of an English villa. Bye-roads lead from hence to the Pria Vermelha, to the royal powder manufactory, and the botanical garden already mentioned. In many parts the Cateta road is in a very bad state of repair, and the holes and hollow places form pools of water after the least fall of rain. The other two roads lead to the north of the city, both branching from the Campo St. Anna, and again communicate in passing Matta Porcas. The first and principal one proceeds from the right of the Campo, and continues for about a mile and a half, to the wooden bridge of St. Diogo, across a marshy flat, which eight or ten years ago was impassable, and is now denominated the Cidade Nova, of which it may in time constitute a portion. The road of the Cidade Nova, being the daily route of the royal family, is kept in pretty good order, as well as the whole road as far as the palace of Christovao, which at Matta Porcas turns to the right, and continues for about two miles along a level, with amphitheatres of various and picturesque mountains in every direction. After crossing the third brook, by a small bridge, the way to the palace turns to the left, when a handsome entrance is discovered, not in unison with the palace, but consisting of a wall and iron palisades, extending about thirty yards on each side of it, without any contiguous lodge or building. From hence the road sweeps to the left, up a gentle acclivity, to the eminence upon which the palace stands, fronted by a square, not embellished with shrubs and grass-plots, but of deep sand, which is entered by the left corner, and not by the grand entrance, composed of the elegant gates, a counterpart of those at Sion House, and sent as a present to his Majesty by the Duke of Northumberland.
