But nearly on a level with the base of the pier, on the east side, a pavement extends from the pier to the Haram wall; and on this pavement rest the fallen voussoirs of the arch. Below the pavement is a mass of debris, and in the bottom of the space is an aqueduct cut in the rock nearly 12 feet deep, arched over, but with the roof crushed in at one place by the voussoirs of a more ancient arch.
Following the aqueduct to the south we presently come to a pool or cistern, 16 feet in diameter; and beyond this the channel turns the corner of the Haram and ends to-day in a drain. Following the aqueduct to the north it brings us to another pool, and presently to a third, this third one being partly underneath the wall of the Haram. The channel was evidently intended to supply the city with pure water, for after the debris had accumulated, shafts were made from the pavement before spoken of, to allow of buckets being let down.
The chief explorers, Warren and Conder, whose matured opinion is given in the Jerusalem volume of the Memoirs, find "no grounds for supposing that the roadway over Robinson's Arch led up to the Upper City, either by steps or by a bridge; it was probably one of the suburban entrances spoken of by Josephus. There may have been other arches in continuation of Robinson's Arch, but there is no indication of this existing on the ground."
Proceeding from Robinson's Arch up the valley, we come to the Gate of the Chain, a chief entrance to the Haram. The street running westward from it is the Street of the Chain, and would bring us, with one little elbow, into David Street, whence we go straight to the Jaffa Gate But in front of the Gate of the Chain it is found that the Street of the Chain passes over a fine arch (now called Wilson's Arch) 42 feet in span, like Robinson's Arch lower down. From an old book, called "La Citez de Jherusalem," we learn that the street coming south from the Damascus
