It appeared sound, but when the soil was

 lower part was found to be so much decayed 

 that the flints fell apart from their own 

 weight. Here, in the middle of the wall, at 

 a depth of 29 inches beneath the old floor and 

 of 49^ inches beneath the surface of the field, 

 a living worm was found, and the mortar was 

 penetrated by several burrows. 



A second wall was exposed to view for the 

 first time, and an open burrow was seen on 

 its broken summit. By separating the flints 

 this burrow was traced far down in the 

 interior of the wall ; but as some of the flints 

 cohered firmly, the whole mass was disturbed 

 in pulling down the wall, and the burrow 

 could not be traced to the bottom. The 

 foundations of a third wall, which appeared 

 quite sound, lay at a depth of 4 feet beneath 

 one of the floors, and of course at a con- 

 siderably greater depth beneath the level of 

 the ground. A large flint was wrenched out 

 of the wall at about a foot from the base, 

 and this required much force, as the mortar 

 was sound ; but behind the flint in the 

 middle of the wall, the mortar was friable,
