"The stations," the author observes, "appear to have been built before the wall, and, as the necessity of the case required that they should be run up as quickly as possible, a smaller class of stone was allowed to pass muster here than was used in the wall. The workmanship is also of inferior quality. The front of the stones, both of the wall and stations, is roughly 'scrabbled' with the pick. In some parts of the line this tooling takes a definite form; when this is the case, the marking called diamond broaching is most common. Sometimes the stone is scored with wavy lines, or with small

squares, or with nearly upright lines. ... It was not until I had become tolerably familiar with the wall, that my attention was called to this peculiar kind of tooling. ... Cuttings resembling mason's marks occasionally occur. Sometimes they consist

of a single or double stroke, sometimes of a diagonal cross, sometimes a rectangular. The other marks which are here represented are less frequently met with."

"Let not the visitor, however, approach it with expectations too greatly excited. There is very much to admire, but not a great deal to strike the eye at first sight. The altars and sculptured figures which lay in profusion on the ground when Gordon and Stukeley were there, have been removed, but the ruins of the place remain as complete and vast as ever. The city is, in a great measure, covered with its own debris, but the excavations which have recently been made show us that, when they are continued throughout the entire station, the ancient Borcovicus will be the Pompeii of Britain."
