Among the other streets which have been widened is the Rua Uruguayana, which starts at the custom house and cuts across the city at right angles to the Avenida Central. It is a broad street for a Latin city, but is not so wide as the other. The Avenida do Mangue is a picturesque street, with its quadruple line of stately palms which run its entire length of a mile or more. Rio is the home of the royal palm, and you see them all over the city. The trees are round and smooth and almost as symmetrical as if cut by a sculptor. No avenue of marble columns can equal these furnished by nature. The Canal do Mangue runs through the centre of the Mangue and there are four driveways along it, two on either side of the canal, as it is very broad. Leaving the palms and following the canal, the avenue makes a broad sweep and leads out to the new docks which are being constructed at great expense. Immense warehouses have been built and great cranes erected, but they are not in use, because it is necessary to dredge a channel before the ocean-going vessels of deep draught can reach the docks. Work is progressing, however, and it will not be long until it will no longer be necessary for vessels to anchor out in the open, and for both passengers and freight to be brought ashore either in launches or row boats. Thus will one of the annoyances as well as one of the big items of expense at this port be eliminated. Along the line of warehouses, and parallel with the harbour line, an avenue has been laid out that is more than three hundred feet in width. This gives abundant room for railroad tracks, tram tracks and driveways for both wagons and pleasure vehicles.
