Kinahan — On frisk Marbles and Limestones. 435 



Wakefield, or Black Quarry (Castlebar). — Dark- grey or blackish, 

 of the Calp type ; very coarse ; can be scabbled, but not fine- 

 worked ; very large blocks can be raised. 



Moneen. One mile from Castlebar. — Bluish-grey; fairly easy 

 to work ; was used when building the gaol and infantry barracks. 



Crossmolina.— Dark- grey to blackish; compact; dense; earthy. 

 It is quarried near Rosserk Abbey, which was partly built of it. 

 Wilkinson points out that it is not a stone to be recommended, as 

 it is brittle, and liable to break off when in work, which, he points 

 out, can be seen in the windows and doorways of the Fitzgibbons' 

 Castle, a few miles north of Castlebar, where a similar stone was 

 used. 



Ballina. — In this neighbourhood the stone is very similar to 

 that of Crossmolina. 



Moyne. Seven miles from Ballina. — Dull- grey; has an irre- 

 gular fracture, but can be worked in any direction, and can be 

 procured in very large blocks. A superior stone for any cut- stone 

 purposes. It occupies a considerable area between Rosserk and 

 Killala, the latter town being built on it ; it also occurs at Moyne 

 Abbey. The durability of the stone and its excellent qualities are 

 exhibited in the Hound Tower of Killala, the Abbey of Moyne, 

 and the cut-stone in Rosserk Abbey. This stone was also used in 

 the mansion of the Knox-Gores, near Ballina, and for cut-stone in 

 the Roman Catholic cathedral. 



Excellent lime is made from the Carboniferous limestone ; also 

 from boulders in the Drift. A Silurian limestone near Toorma- 

 keady is said to be hydraulic. Near Cong there is a clay which, 

 if mixed with lime, makes it hydraulic ; used extensively at Cong 

 in the river works, and at Lord Ardilaun's fountain. 



Meath. 



Carboniferous limestone occupies the principal part of the 

 county, but it is divided into north and south districts by a tract of 

 arenaceous and slate rocks. The stones in the southern district 

 partake very much of the Calpy nature of the rocks in the Co. 

 Dublin, while very superior stones are procured in the northern 

 division, the quarries of Ardbreccan and Rosscastle, or Cashel, being 

 extensively known ; also the neighbouring quay of Crossagh.
