Note 23 — Chapter II
Reading edition
The line of mounds now marking in places the position of the city-wall is formed, oddly enough, by the core of the mud-brick portion, which still stands above the level of the surrounding soil. The far stronger outer wall has completely disappeared, for its fine burnt-bricks have tempted plunderers in search of building material. It is only after excavation that the lower courses of its foundation are detected when still in place. It is possible that deep excavation may settle the position of the whole line of walls, even where no trace of them now remains upon the surface.
