security, beyond the precaution of filling up the cavities with the solid material which had been previously removed. The fact that the plan as we now view it, refers only to the foundations, presents a difficulty with which it is impossible to contend successfully; there is no accounting for the purpose intended by the introduction of several of the walls—they are all bound together in so complicated a manner that no distinction can possibly be made between those designed merely as ties for security, and others provided to support the principal weight of the superstructure.
This baffles conjecture as to the order of the principal rooms; their position, facing the east, admits of no doubt, and it would not be difficult to arrange a plan to suit these remains, however unsafe it might be to attempt a description of what we may suppose the house to have been when perfect.
The floors of several of the lower range of apartments remain in a tolerably perfect condition, and, judging from the appearance of the ground during the recent excavation, accumulation has carried it above their level, whereas at the time of building, these basement floors were above the surrounding ground. The external walls are 2 feet 8 inches and 2 feet 6 inches in thickness, and not many of the cross walls are of less substance. They are uniformly composed of flint and chalk, well compacted and laid in courses, the external angles being formed of brick of the usual dimensions: this material occurs in layers in other places, but was not generally used underground except to give firmness to the angles, and in these positions the quantities were not sparingly applied, as may be seen by reference to the annexed figure. The floors of the rooms were mostly overlaid with composition of light colour, but two, opening to each other, one towards the south, 12 feet 10 inches by 11 feet in the wing, the other 26 feet 2 inches by 9 feet 2 inches on the west side, were finished in a superior manner, having had a kind of skirting formed of concrete and finished with cement, the floors being laid with the collected fragments of tessellated pavements and freestone, bound together with gravel and lime, and forming an even and solid floor, the strength of which has not been materially impaired by the damp which has proved so destructive to a portion of the materials of the walls. It should be observed that as soon as the foundations were constructed, the inside surface of the walls throughout were coated with plaster—a coarse composition of broken brick and lime, and then the hollows filled with rubbish to a level height, and covered with the floors composed in the manner described. The principal hypocaust has a double line of brick pillars remaining, five courses high, near the north wall, which is pierced with two flues in a vertical direction, 12 inches in width, but its perfect form is not seen. Attached to the west wall and extending in nearly parallel lines, are four distinct walls of flint, indicating that this part, at least, required a preparation of greater strength than that afforded by brick piers 7 inches square. These walls were added at the time of some alteration in the building over, as the plaster appears on the boundary wall in places where these flue walls have been destroyed—they are 2 feet 6 inches, 2 feet 4 inches, and 2 feet 3 inches in thickness, 10 inches apart; and attached to one, is a brick pier, the recommencement of the usual mode of construction beyond the point where the necessity for the stone-work ceased.
