tion of the east wall at all points, because a Mohammedan cemetery covers the ground, and excavation among the graves is forbidden. It was only by sinking shafts at a distance from the wall, and employing a method of laborious tunnelling, that the depth of the foundations could be ascertained. Warren's work hereabout has been pronounced by Sir Charles Wilson to be without a parallel in the history of excavation. "In one shaft alone no less than 600 feet run of shaft and gallery was excavated."
If we might only explore freely within this cemetery Warren is confident that we should come upon those huge stones—20 cubits long and 6 cubits thick—which Solomon laid down on this side when he built the temple (Josephus, Ant. xx. 9,7). One would suppose that the present north-east angle, added by Herod, was of much later date than the south-eastern; yet here again "Phœnician" masons' marks are found. Masons' marks, however, may have a tendency to remain the same through many ages. It is a curious fact that the red paint with which they were put on has "run" in one instance, while still wet, and the trickling is upwards as the stone stands in the wall. This shows that the marking was done before the stone was placed, and very likely at the quarry.
North of the Haram enclosure.—The excavations just referred to were sufficient to show that a deep valley once existed to the north of the Temple, as described by Josephus, in "Antiquities" xiv. 4, 2 and "Wars" i. 7, 3, where he states that Pompey found it a difficult business to fill it up. This valley commences to the north of the city wall, passes down west of the Church of St Anne, and runs into the Kedron, past the Sanctuary wall, at a distance of 145 feet south of the north-east angle. The great reservoir, called the Birket Israil, which extends along the northern side of the Sanctuary for 360 feet, lies across this valley. It is 126 feet wide and 80 feet deep. The west
