 pice, a piece about five feet high, and feve- 

 ral yards long ; the facing is of regularly 

 Cut free ftones, but I meafured none q£ 

 them above thirteen inches long and fevea' 

 broad ; the mortar in the facing is quite 

 gone, but much of it remains in the mid-

 entrenchment, thrown up for the fame pur-

 in that Hate : It is foft at firfl, but hardens
