thofe encompafled with one rampart and fofTe, 2. thofe 

 with more than one, and 3. thofe with outworks. The 

 firft clafs like that near Saintfield, and of which I have 

 given a drawing, is the leaft frequent ; the outfide of 

 the rampart is in circumference near two hundred 

 yards, feven in breadth, and the ditch five ; the height 

 in a (loping direction near forty feet. The fecond with 

 more than one inclofure, of which that near Downpa- 

 trick is a juft reprefentation ; this mount takes up a 

 eonfiderable extent, not lefs than three quarters of an 

 Englifh. mile in circumference ; three artificial ramparts 

 furround it, the greateft of which is thirty feet broad. 

 The third kind has generally a fquare fort or redoubt 

 adjoining to the main trench, and fometimes other 

 works, which render them very defenfible, fuch as the 

 mount at Dromore : this mount is fituated at the north- 

 eafl extremity of the town, above the river Lagan, its 

 circumference nearly fix hundred feet, the perpendicular 

 height near fixty feet, the diameter at the fummit fifty- 

 five feet ; the whole furrounded by a rampart and bat- 

 tlement ; the trench, which terminates on a precipice, 

 has two branches embracing a fquare fort of an hundred 

 feet in diameter. From the Lagan to this ancient for- 

 tification is a covered way upon the defcent of the 

 precipice, two hundred and fixty feet in length, feven 

 feet wide, and nine feet deep. All this will more 

 plainly appear by infpecTring the annexed plan, as alfo 

 the remains of a walk towards the fouth, in which di- 

 re&ion are the ruins of a caftle at a fmall diftance.
