up to late years being on those then known, or on branches from 

 them. 



These lodes seem all to have been in the region of the junction 

 between the Grranyte and Schist, in the first being more or less rich, 

 in the latter in general poor or nearly valueless ; while in a few 

 places at the contact there were good bunches of ore. In Grlendas- 

 san, associated with the galenite, were cerusite, sphalerite, and pyro- 

 morphite, the lead ores (galenite and cerusite) giving eight to ten 

 ounces of silver to the ton. Of the numerous veins the largest 

 was that called the Camaderry lode. In late years, on account of 

 the low price of lead, the works gradually slackened off till 1880, 

 when they came to a stand still. 



The lead veins in Grlendalough were remarkable, being asso- 

 ciated with chalybite (carbonate of iron), the latter in one place 

 being eight feet wide. The workings on these lodes have been 

 discontinued for years, the lead veins being too small to pay at the 

 low prices for lead. 



In Grlenmalure there are numerous small lodes, or strings of 

 lead, all of which have been more or less explored. The only 

 mine that gave returns was that at Ballinaf unshogue, to the east 

 of the River Avonbeg. This, when in full work, was stopped, the 

 lease having expired, and excessive terms, it is said, being asked 

 for a renewal. The ores in the lode were galenite, barytes, 

 sphalerite, and specks of chalcopyrite. 



To the west of the Avonbeg, at Baravore, there are appear- 

 ances of a good lode ; but only partially explored. Here barytes 

 was in quantity, and of very good quality. In Clonkeen with 

 the le&d there was chalybite. 



Westward of Glenmalure, at the North Prison, Lugnaquilla, 

 is a lode of lead, very favourably reported on by the late Henry 

 Robinson ; but it is very difficult of access. Lead also occurs 

 to the southward of Lugnaquilla, at the waterfall, northward of 

 the Aghavannagh Barracks. 



Eastward of Grlenmalure lead is recorded, at Cullintra Park 

 and at Loughs Dan and Tay, &c. Lewis states the lode at Lough 

 Dan is worked out. 



The localities for the gold and tin found in this county are 

 given in the Lists, Part I. In connexion with a " gold digging "
