are at some distance from the river. It is much cut up by ravines, and is quite 

 uneven. 



The main body of the work is situated upon a very beautiful level, somewhat 

 ascending to the east. The wings are on equally beautiful levels, except that they 

 are broken at two or three points by ravines. 



The principal work is an exact rectangle, eight hundred feet square. The walls 

 are about twelve feet high, by thirty-five or forty feet base, except on the east, 

 where advantage is taken of the rise of ground, so as to elevate them about fifty 

 feet above the centre of the area. This feature is exhibited in the section a b. 



The hollow way between the south-eastern wall and the terrace Bank beyond 

 seems artificial, — at any rate, it has been modified by art. The gateway on this side 

 is entered by a slightly elevated causeway. At the southern angle is a bastion, pro- 

 bably natural but adapted by art, which commands the hollow way or ditch. The wall 

 at this part is distinctly marked, but not more than three feet high. On the south- 

 western side is a sort of runway, resembling a ditch, which loses itself in a deep 

 gully towards the river. It is undoubtedly wholly or in part artificial. There are 

 no traces of ditches elsewhere about the work. A narrow gateway thirty feet 

 wide opens in the middle of each side, and at the northern and western angles, as 

 repi'esented in the plan. 



The most singular features of this structure are its outworks, which consist of 

 parallel walls leading to the north-east and south-west. They are exactly parallel 

 to the sides of the main work, and are each two thousand one hundred feet long. 

 Some measurements make them of unequal lengths ; but after a careful calculation of 

 the space occupied by the interrupting ravines, they are found to be very nearly, 

 not exactly, of the same length. 



The parallel to the south-west has its outer wall in line with the north-western 

 wall of the main work, and starts at thirty feet distance from the same. It is broken 

 by a deep ravine near its extremity, which is probably four or five hundred feet 

 wide. Crossing the ravine, the walls, traces of which are seen on the declivity, 

 continue to some distance, and then curve on a radius of one hundred feet, leaving 

 a narrow gateway eight feet wide in the centre. Converging walls start from the 

 point of curve, but lose themselves after running three hundred feet, without meet- 

 ing. Just beyond and a little to the right, on the plain, are two clay mounds, also 

 a small circle one hundred feet in diameter, the walls of which are two feet high. 



The parallel to the north-east starts from the centre (nearly) of the main work, 

 and is similar to the one already described, save that it is not terminated by 

 converging walls, and has no mounds beyond. It is interrupted by two ravines, 

 the walls running to their very edges. The left wall of the parallel bends to a 

 right angle as it approaches the main work. 



To the left of tliis parallel, four hundred and fifty feet from a point eight hundred 

 feet distant from the main work, on a high peninsula or headland, is a singular 

 redoubt, an enlarged view of which is given in the supplementary plan N. To 

 the left of it is the bank of the second bottom, fifty feet high, and very steep. To 

 the right is the hollow of a small stream with steep banks. The embankment of 

 this work is heavy, and the ditch deep and wide, and interior to the wall. From
