14 STATISTICAL SURVEY 



feen as a ftep to the communion-table of the church 

 of Hilliborough; it is twenty-one feet in length, and 

 two in breadth. 



Slates are raifed in the following places ; from 

 Bangor to Ballywalter, of a great fize, and excellent 

 metal, rather heavy, but which ftand the weather very 

 well; alfo in the parifh of Doomarah, not far from 

 HilHborough, at Annahilt, and near Ballynahinch. 

 Thefe quarries all produce flates when funk to a 

 proper depth, which, if they do not equal thofe im- 

 ported from Wales in lightnefs and colour, exceed 

 them very much in hardnefs and durability. Befides 

 thofe above mentioned, there are numerous quarries of 

 this ufeful material in other parts of the county, which 

 require nothing |iore than to be worked with fkill and 

 honefty, to fupply the wants of the circumjacent 

 country in that neceflary article; but where, from 

 want of (kill, the blocks are not raifed of a proper 

 fize, and the flates, from want of honefty, are broken 

 to encreafe the number, we need not be furprifed that 

 thefe quarries do not fucceed. 



Limeftone is not very general ; very large blocks of 

 a yellow kind are in great abundance near Cultra, on 

 the jfhore of Carrickfergus bay ; likewife at Carthefpie, 

 on the fliore of Strangford lough, near Comber, there 

 is a reddifti coloured granular limeftone, very hard and 

 fparkling; but the great, and probably inexhauflible 

 magazine of this moft ufeful foflil, is found in the vici- 

 nity
