Kinahan — On Irish Marbles and Limestones. 421 



Tjiocks, it is suitable for massive work. From this were obtained the 

 large cap-stones for the pillars of the Boyne Viaduct. They were 

 tilso extensively used in the construction of the Lighthouse on 

 Jlockabill. 



Donnybrook and Miltown. — Here formerly were extensive quar- 

 ries, principally in the river and to the eastward of it, but now 

 they are very little worked. Dark-grey to blackish, earthy ; 

 suited for foundations and rubble- work, but not for cut-stone. It 

 was, in a great measure, the use of the Donnybrook Calp in 

 repairing the streets that got for Dublin the soubriquet of " dear, 

 dirty Dublin." 



Eathgar. — From pale to dark-grey and blackish ; from thick- 

 bedded to good flags. This quarry was once extensively worked. 

 The ordinary stones were good for rubble-work, and the flags of a 

 very fair quality. The best beds, being nearly equal to the 

 il Carlow flags," were extensively used. 



Kimmage and Crumlin. — The stones in these quarries are more 

 or less similar to those at Donnybrook, Miltown, and Rathgar. 

 These supply to a great exteut the rough and foundation stones 

 now required in Dublin. 



Ballymacauly and C oilier stoivn. — On the Royal Canal, between 

 Leixlip and Lucan. From these quarries were taken the stones to 

 build the Dublin Custom-house docks. Formerly very exten- 

 sively quarried. 



Lime from the Calp is, in general, dark-coloured and inferior, 

 some beds being, however, very good. A great deal of the lime- 

 stone used in Dublin for lime is brought from the neighbourhood of 

 Slane, Co. Kildare. 



At the present time the limestone which appears to be most 

 approved of by the Dublin builders is the Ballinasloe, Co. Gralway, 

 stone, which can be seen in the Hibernian and Munster (Head- 

 office) Banks ; next to it the Tullamore, King's County, the latter 

 being much in request for monumental purposes, and was used in 

 the monument at (rlasnevin to the late Under-Secretary, Mr. 

 Burke. The Ardbraccan stone, Co. Meath, although it has a 

 good appearance when finished, is soft, and does not keep its 

 colour ; and with it is classed the Ross Castle stone, Co. Meath ; 

 but the stone from the neighbouring quarry at Crossagh, although 

 coarser, is more favourably thought of. The Milverton stone, near
