In Fig". 14, we see a section across the 

 paved floor of the southern corridor or 

 ambulatory of a quadrangle, in an excavation 

 made near "• The Spring." The floor is 7 

 feet 9 inches wide, and the broken-down 

 walls now project only | of an inch above its 

 level. The field, which was in pasture, here 

 sloped from north to south, at an angle 

 of 3° 40'. The nature of the ground on each 

 side of the corridor is shown in the section. 

 It consisted of earth full of stones and other 

 debris, capped with dark vegetable mould 

 which was thicker on the lower or southern 

 than on the northern side. The pavement 

 was nearly level along lines parallel to the 

 side-walls, but had sunk in the middle as 

 much as 7f inches. 



A small room at no great distance from that 

 represented in Fig. 13, had been enlarged by 

 the Roman occupier on the southern side, by 

 an addition of 5 feet 4 inches in breadth. For

 been pulled down, but the foundations of the 

 old wall had been left buried at a little depth
