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 at some 

 little distance 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

 old wall had been left buried at a little depth
