28 Mr. Weaver on the Geological Relations of the South of Ireland. 



(43.) The Kenmare limestone field (§ 23.) extends from west to east, through the following 

 properties, opposite to which are placed the indications of metals observed in each respectively. 



TOWNLAND*. PROPRIETOR. INDICATIONS. 



Reens Mr. Langford. Galena, copper pyrites, and blue and green car- 



bonates of copper, with calcareous spar. 



Dunkerrin Dr. Thos. Taylor. Galena. 



Tibburid Rev. Mr. Mahony. 1 Iron ochre, galena, and iron pyrites, with cal- 



GurtamuUin Ditto. J careous spar. 



Kenmare town Marq. of Lansdowne. Galena with calcareous spar. 



Killowen Ditto. Galena, blende, iron pyrites, and iron ochre, 



with quartz and calcareous spar. 



Gurtagass & Cleady , Trinity College, Dublin. None observed. 



West Cahir Marq. of Lansdowne. Iron ochre, blende, galena, iron pyrites, and 



green carbonate of copper, with calc. spar. 



East Cahir Ditto. None observed. 



Clontua Mr. J. Dillon Croker. Galena, blende, iron pyrites, yellow, grey, and 



purple sulphurets of copper, with blue and 

 green carbonates, and calcareous spar. 



Ardtully Proper Ditto. Iron ochre, and copper pyrites, with calc. spar. 



Kilpadder Mr. Townsend Orpen. Copper pyrites, with calcareous spar. 



In the slate, adjoining the limestone on the north, are also the following indications. 



In East Cahir Compact indurated oxide of iron. 



In Clontua Green carbonate, grey and purple sulphurets 



of copper, and indurated oxide of iron. 



The above-mentioned metalliferous indications appeared for the most part of a confined, local 

 character, bespeaking no permanent extension ; yet, some seeming to deserve research by actual 

 working, trials were made in Killowen in separate places to the respective depths of 42, 33, and 

 15 feet; in West Cahir to the depths of 45, 46, and 25 feet ; and in Ardtully Proper to the 

 depth of 15 feet. But in all these cases, however promising the appearances at the surface, the 

 mineral deposits proved discontinuous, dividing and contracting so as finally to disappear, and 

 thus penetrating the rock only to a small extent either in length or depth ; yet in their position 

 they were always nearly parallel to the range and dip of the bed in which they were included. 



The same results clearly followed the researches of former adventurers, made on the lands of 

 Reens and Kilpadder, extending only a few fathoms in depth. The most extensive of the old 

 trials were made in Clontua in the form of four open-casts, respectively GO, 80, 28, and 10 fathoms 

 in length, two being on the same range, and two parallel to each other. The deepest did not ex- 

 ceed 6 or 7 fathoms in depth, while none of the others penetrated beyond 10 feet. In these trials, 

 as in others already mentioned, were chiefly found layers of calcareous spar of uncertain continuity, 

 and bearing ore more or less sparingly. 



Researches were also made in the slate, north of the limestone, in East Cahir and in Clontua. In 

 tlie former, the old adventurers had made an extensive open-cast and sunk some pits ; but no 

 ore appeared at the surface beside indurated oxide of iron. Workings, more recently instituted,
