 forms a passage of dbout 360 feet in length, leading 

 by a gradual descent to the low grounds, where it 

 probably at the time of its construction reached the 

 tnargin of the river. Its walls commence at sixty 

 feet from the ramparts of the fort, and increase ia 

 elevation as the way descends towards the river; 

 and the bottom is crowned, in the centre, in the man-

 walls of the fort, at the different corners, are elevat- 

 ed squares, some of which are 188 feet long, and 132 

 broad, and nine feet high, level on the summit, and 

 nearly perpendicular at the sides. Circular mounds 

 are also seen, thirty feet in diameter, and, five in 

 height. 



Towards the south-east is a smaller fort, contain-

 defended with circular mounds. 



On the outside of the smaller fort, is a mound, in

 which strike the beholder with astonishment. Its
