 also in Monaglogh and Coolbawn.

A collection of papers appearing in the Sci. Proc. Roy. Dublin Soc., from March 

 1886 onward. Three counties in which tin is said to be found: 



1. County Dublin, Dalkey, at Kingstown with lead and zinc in granite. Only place 

 in Ireland that it is known in a lode. Rumored at Kilcrohane (Sheep Head) County 

 Cork, but not authenticated. 



2. County Kerry, Lough Leane, Killarney. Questionably. 



3. County Wicklow, Goldmine River, Woodenbridge, in gravels with gold and mag- 

 netic sand. Suggests possibility of finding tin lodes at last place.

Trans. Inst. Mg. Eng., Vol. 26, 1908, London and Newcastle-upon-Tyne, pp. 279-280, 

 286. 



Tin ore in the Ovoca district, County Wicklow, has not been found in place. 

 Thinks it may occur in copper-bearing veins in the district and that copper may give 

 way to tin in depth. Treats shortly of old bronze, showing that tin was known in 

 Ireland long ago. 



Only localities where tin is known are Dalkey, County Dublin, and the Goldmine 

 Valley, County Wicklow. Said to have been found near the lakes of Killarney, 

 County Kerry. 



H. J. Seymour is quoted as crediting minute crystals of cassiterite to the Mourne 

 Mountains.

States that in the Croghan Kinshelagh area, County Wicklow, Ireland, " the black 

 sand is composed mainly of magnetite, ilmenite, hematite and iron pyrite, but 

 cassiterite, galena, wolframite, molybdenite, gold, copper-pyrite and oxides of man- 

 ganese also occur in the sand. The late Mr. W. Mallet records having obtained from 

 a washing of 150 pounds, no less than 3% pounds of stream tin, in all sizes from 

 small grains up to pebbles ^ inch in diameter and of the variety known as wood-tin."

Tin in County Wicklow, Ireland, " Should this mineral be found in the mass of 

 sand in a quantity at all approaching that in which it existed in the specimen 

 examined, it would probably richly repay the labor and expense of collection and 

 smelting. The fact of the existence of tinstone in such considerable quantity in these 

 auriferous streams, would seem to indicate the probable existence somewhere in the 

 surrounding district of masses of ore, and possibly forming the continuation of those 

 vast deposits of Cornwall."
