“The old wall, on its being repaired, was carried up of the same thickness to eight or nine feet in height; or if higher, there was no more of that work now standing. All this was apparently additional, and of a make later than the other part underneath it, which was levelled and brought to a plane for the raising of this new work upon it. The outside, or that towards the suburbs, was faced with a coarse sort of stone, not compiled with any great care or skill, nor disposed into a regular method; but on the inside there appeared more marks of workmanship and art. At the bottom were five layers composed of flint and free stone; though they were not so in all parts, yet in some the squares were near equal, about five inches diameter, and ranged in a quincunx order. Over these were a layer of brick, then of hewn free stone, and so alternately brick and stone to the top. These bricks, of which there were four courses, were of the shape of those now in use, but much larger, being near eleven inches in length, five in breadth, and somewhat above two and a half in thickness. There was not one of the Roman bricks above mentioned in all this part, nor was the mortar here near so hard, as in that below; but from the description may be easily collected, that this part when first made, with so various and orderly a disposition of the materials, flint, stone, and brick, could not but carry a very handsome aspect. Whether this was done at the expence of the Barons in the reign of King John; or of the citizens in the reign of King Henry III. or of King Richard II. or at what other time, I cannot take upon me to ascertain, from accounts so defective and obscure as are those which at this day remain of this affair. “Upon the additional work now described, was raised a wall wholly of brick, only that it terminating in battlements, these were topped with copings of stone. It was two feet four inches in thickness, and somewhat above eight feet in height. The bricks of these were of the same module and size with those of the part underneath, How long they have been in use is uncertain.” _Woodward’s Roman Antiquities, and Present State of London._
