foot of the interior slope at s, as wide as you please, say ten 

 feet, digging down to t, v, so as to be well below the old 

 surface line g, l, z, which m your soil will probably only be 

 marked by a little white decayed matter representing the old 

 turf. Whatever is found in the hochj of the rampart, a, m, n, l, 

 and especially on the old surface line a, l, must be of the date 

 of the construction of the camp or earlier ; but things found 

 in the silting of the interior slope, m, g, a, may be of various 

 dates subsequent to the construction of the camp, the age of 

 an object thus found depending upon its proximity to the old 

 foot of the interior slope a. This is- a very important point 

 to notice, as any mistake between the hodij of the rampart 

 and the silting would give an entirely false idea of the date. 



" In like manner the ditch should be dug in spits down 

 from the top. What is found in the upper spit is quite 

 recent ; the second spit older ; and things of the date of the 

 camp will be found only in the bottom spit. 



"It will be found that the point i, marking- the 'present 

 centre of the bottom of the ditch, is always to the outside of 

 the old bottom, k, — perhaps 3 or 4 feet, according to 

 circumstances, but always outside, — more silting having 

 gone fi-om the rampart into the ditch than into the interior. 

 I have had sometimes to dig down as much as 3 feet 

 below G before finding the old surface line. The old surface 

 in this place must have been very uneven at the time the 

 rampart was made." 



Fig. 2, Plate IV., is a section, by Mr. D'Oyley, through 

 the centre of the cutting at Ambresbury Banks, showing the 

 seams in the rampart and ditch, and the position of each 

 object found. As the position of the objects in a vertical 

 plane is all that is necessary to take notice of, everything is 

 projected in this section. Each object as it was found was 

 numbered, put into a small pill-box, ticketed on the spot, 

 and marked on the section. At the conclusion of the exca- 

 vations the entire collection was sent up to me for comparison 

 with similar objects found in the ramparts of other camps. 

 The following were the objects found : — 



No. 1. An outside flint flake with bulb of percussion, and
