To avoid the risk of water-logging, the burnt brick facing of the bath was backed by a layer of bitumen, and beyond this again was a thickness of puddled clay between two brick walls. Presumably the floor as well as the walls was so treated, but it is impossible to test this point without destroying a portion of the pavement, whose excellent state of preservation deprecates any damage being done to it. Despite these ingenious precautions, a small amount of subsidence has actually occurred, though not apparently destroying the water-tightness of the bath.
