Enniscorthy — Ordovieian. — The work- 

 ings here appear to have been ancient, 

 as nearly all traces of them are 

 obliterated. 



Gorey — Ordovieian. — These accumula- 

 tions are in" part 'of the nature of 

 • beds. At and in the neighbourhood 

 of Ballynastragh portions of a bed or 

 beds of purple slate are highly ferri- 

 ferous [limonite). Near Courtown 

 the same ore occurs as strings or 

 veins in the rocks, while northward 

 of Bally money Fishery there are 

 lenticular beds of poor chalybeate. 



Blessington (Glenasplinkeen) ■ 



morphic Ordovieian. — Limonite, hema- 

 tite, and manganese ; worked a little. 



Shillelagh — Metamorphic Ordovieian. — 

 Limonite. Some trial made on the 

 vein about 1875. Iron ore is said to] 

 have been raised in this locality in 

 Bacon's and Chamney's time (16th[_ 

 and 17th century) ; but the sites_of 

 their works are now unrecorded. 



North of . . — Metamorphic Ordovieian. 

 — A ramp of limonite partaking of 

 the nature of hog-iron-ore; for the 

 most part at the surface, or only under 

 a thin drift : in places it is copper- 

 stained. No traces [of old or recent 

 works in connexion with it are appa- 

 rent. 



Eathdrum — A rather extensive ferrife- 

 rous conglomerate on Metamorphic 

 Ordovieian (?). Unsuccessfully open 

 casts were made in part of it (1875), 

 to try and find its source. 



Woodenbridge, Carysfokt Mines — 

 Metamorphic Ordovieian. — Limonite : 

 the backs of copper and sulphur- 

 ore lodes. Very ancient working 

 appears to have existed here ; while 

 in recent years some tons of ores 

 have been raised at Moneyteigue. 



Arklow — Metamorphic Ordovieian. — 

 A large ferriferous mass, somewhat 

 like that at Mucklagh. No trials 

 have been made to seek for its 

 source.
