the mode of construction, nor of the cost of this noble work, nor given any hint of the

quantity of water brought into the city by it. The supply of this aqueduct is derived from the mountains of Cintra. Its course is

between 8 and 9 miles, and it terminates in the city, in a Chateau d'Eau or Castellum, whence the waters are distributed to numerous fountains. Lisbon is built upon the slope of a hill, over the top of which, the waters of the aqueduct are introduced.

Lofty, therefore, as are the houses, there is head enough to carry a supply up to the attics, yet here, as in Rome, not a pipe, as is believed, is laid to any house in the city a corps ;

of water carriers, of Spanish descent, and from their province of Gallicia, taking the name of Gallegos, effect the distribution of the bountiful outpouring of this noble aqueduct, and are to be seen at all hours of the day, toiling up the stone stairways of the loftiest houses, bearing on their head or shoulders, an earthen vase, containing almost a barrel of water. With this grandest of modern European aqueducts, we terminate our notice of such constructions in the Old World, and turn to America, where, earlier than is recorded, aqueducts have existed.

aboriginal inhabitants of that portion of America, now constituting the United States, * Murphy's Travels in Portugal, 4to ed., p. 183.
