Bullock granites, but not as durable. At first it is superior as to 

 colour ; but when wheathered, it is much the same in that respect as 

 the others. On account of its ready dressing and of its being 

 worked at the quarries by the native workmen more cheaply than 

 it or any stone could be when carted to the buildings in course 

 of erection, it has been largely used in Dublin. " Probably 

 a better evidence of the difference in working quality, and of the 

 value of the facility of conversion, as compared with the cost of 

 carriage, could not be adduced than the station-house and offices at 

 Kingstown, of the Dublin and Kingstown Railway, which, although 

 built on the solid granite rock, are constructed with stone brought 

 from near Blessington — a distance of twenty miles." {Wilkinson.) 

 These granites have been already specially referred to. 



In other places in this neighbourhood small quarries have been 

 opened, and good stones procured ; all, however, have gone into 

 the market under the name of " Blessington granite," and none of 

 the workings have been extensive enough to have received a special 

 name ; it is, therefore, only necessary to state that in this locality 

 good stone could be procured in other places if quarries were 

 opened. Elsewhere, in the tract of the granite of the " Leinster 

 type," the quarries that have been wrought in different places 

 seem to have been only for local use, or some special purpose, as 

 the stone from these is not known in the general market. 



Ballynaclash, S.W. of Eathdrum, a dyke of fine elvan ; at one 

 time worked for paving-setts, for which it ought to be suitable, if 

 the quarry was continued in depth. 



Car rick, south of Rathdrum {Aughrim type), " Fitzwilliam 

 quarry." Grrey, even-grained, but containing more or less marca- 

 site, which causes discolouration, was extensively quarried during 

 the construction of the railway from Dublin to Wicklow. 



''Aughrim, close, fine, and easy to work, used with Grlencullen 

 granite, for sills, steps, and other dressings in the Arklow and 

 Kilmichael (Co. Wexford) 0. Gr. stations; and with Carlow granite 

 in those at Curracloe and Rosslare, both in Co. Wexford. The 

 Carlow granite is a good variety, soft and close, hard and coarse, 

 good and bad colour." (J. W. Mellon.) Extensively used on the 

 railway between Killiney and Kingstown ; also on the " Loop 

 Line," Dublin. 



Tinnakilly, north-east of Aughrim, worked in different places. In
