An evidence of the durability of these old Roman structures is furnished in this junction of water from Lake Bracciano by Cardinal Orsini, under authority of Clement X., upon condition that a part of the water should be used to feed a second fountain about to be built in St. Peter's Square atRome, and the rest to be divided between the Apostolic Chamber and the House of Orsini. From the lake the conduit leads to the old Alsietina Aqueduct, in which it flows 20

miles to the city, and it was found to be in so perfect a state when the trial was first made after the restoration, October 13th, 1693, that all the water which entered the old Aqueduct

was discharged at Rome without any loss, after its use had been suspended nearly 1000 years.

Aqueduct of Caserta.

This Aqueduct was built by the order of the King of Naples, Charles III., for conducting water to his residence which he had at Caserta, a town situated about fifteen miles north of Naples.

This Aqueduct was commenced in 1753. It is twentyseven miles long, from the sources which supply it to the gardens of Caserta. The sources are at the base of the mountain called Taburno; the principal one is called Sorgente de la Sfizzo; it is afterwards joined by streams from many other sources, which are in the country called

Airola.

These waters are all joined in one Aqueduct, crossing the river Faenza, upon a bridge of three arches, built in 1753.
