face, while the joints were so perfect that it was nearly impossible 

 to insert the blade of a knife between them. 



Minnard. Seven miles from Dingle. — Red ; very fine ; a good 

 colour ; very durable ; can be raised in large blocks ; was used for 

 ashlars and face- work in the Roman Catholic church, Dingle. 



Mr. Deane also mentions " a green stone in the Dingle dis- 

 trict, used for building purposes." 



Ventry. — Yellowish-brown ; compact ; not heavy ; easily 

 worked. 



Killamey. — Dark-grey ; very silicious ; slightly granular. 



Batty carberry (Iveragh). — Purplish-grey; very silicious ; slightly 

 micaceous. 



Devonian and Carboniferous. — These vary from coarse conglo- 

 merates to a fine-grained sandstone or grit. They are often flaggy, 

 and for the most part are reddish, purplish, or yellowish in colour. 

 In general they are durable, and many of them can be raised in 

 blocks of greater or less dimensions, being eminently suitable for 

 rough work, such as piers, bridges, and foundations. They are 

 also capable of producing good, sound, fine work, as exemplified in 

 the ancient structures. Rattoo Round Tower, in the Kerry Head 

 district, appears to have been built from a hard quartzose sand- 

 stone, procured in the vicinity ; and it displays a cut-stone band 

 round the doorway in good preservation. 



In Derryquin Castle, which is principally built of the slate 

 rock of the locality, some of the quoins are, to quote Wilkinson, 

 " of a grey-coloured sandstone resembling pumice-stone, which is 

 soft, and works in any direction, but hardens and becomes very 

 durable on exposure. It is found in a long, narrow vein, adjoining 

 the red sandstone, and occurs near the coast, continuing inland 

 towards the Staigue fort." 



Poulawaddra Wood. Three miles from Tralee. — Red ; soft ; 

 fair- working ; Lord Kenmare's castle, Killamey ; new Railway 

 Station, and various houses in Tralee. 



Tonenane. Three miles from Tralee. — Similar stone to that at 

 Poulawaddra ; used in both of the Roman Catholic Churches, 

 Tralee, and other smaller structures. 



There are other smaller quarries in Slieve Mish besides those 

 mentioned. Mr. W. H. Deane, County Surveyor, considers the
