by the masons, as though repairs and alterations in the buildings were going on at the very moment of the final catastrophe. Adjoining to this hypocaust, at its north-west corner, is a square room, c, with the herring-bone pavement, exactly like that at _u_ in character and dimensions, which had opened into the room above the hypocaust B, much in the same manner as _u_ opened in the room _v_. Separated from this room by a wall, but apparently without any communication with it, is an interesting staircase D, leading down, to the entrance to a larger and apparently more important series of hypocausts. This staircase descended from a square room, about the same size as the room C, which had a smooth pavement of cement. It is composed of three steps each formed of a large squared stone. A part of the space at the bottom, the north-eastern corner, appears to have been used by the later Roman inhabitants of this building as a receptacle for the sweeping of the floors, and when it was first opened the earth, to the height of about sixteen or eighteen inches from the floor, was filled with all kinds of objects, such as coins, hair-pins, fibulæ, needles in bone, nails, various articles in iron, bronze, and lead, glass, broken pottery, bones of edible animals and birds, stags’ horns, tusks and hoofs of wild boars, oyster shells, in one of which lay the shell of a large nut, &c. A large shaft of a column lay across the steps. The Roman masonry here is very good. To the right hand, towards the south, a rather large arch, turned in Roman bricks, led into the hypocaust E, a doorway in the southern wall of which formed the communication between this hypocaust and the still larger hypocaust F. The latter had supported what must have been a handsome room, which was about fifty feet long, including the semicircular northern end, by thirty-five feet in breadth. When first opened, this hypocaust was in a state of preservation in which such buildings are seldom found in this country. A hundred and twenty columns of bricks were counted, most of them at their original height of rather more than three feet. At the north-eastern corner, the columns supported a small portion of the floor in its original position. It is a mass of cement, eight inches thick, with the upper surface, which no doubt had formed the floor, perfectly smooth. During the time that the Excavation Committee were excluded from the field, all the pillars of this interesting hypocaust were thrown to the ground, and a great part of the bricks which formed the supporting columns were broken to pieces—even the piece of the floor and its supports at the north-east corner were overthrown. A very exact drawing of the latter, however, had been preserved, which served as a pattern for restoring it; and it is to the ingenuity and labour of Dr. Henry Johnson that the public owes the restoration of this hypocaust as far as it was possible to restore it.
