ecclesiastical establishment ; it is mentioned by the Four Masters, at 

 1323, and called Cluain-da-rath, the meadow of the two raths ; and 

 there is a townland of the same name in the parish of Tisrara, Eoscom- 

 mon. Near Crossmolina is a townland called Glendavoolagh, the glen 

 of the two boolies, or dairy places. 



The parish of Donagh, in Monaghan, takes its name from an old 

 church, the ruins of which are still to be seen near the village of 

 Glasslough ; it is mentioned twice by the Pour Masters, and its full 

 name, as written by them, isDomhnach-maighe-da-chlaoine, the church 

 of the plain of the two slopes. Dromdaleague, the name of a village 

 and parish in Cork, signifies the ridge of the two stones ; and Dadreen 

 in Mayo, is the two dreens, or sloe-bushes. 



Several places derive their names from two plains : thus Damma, 

 the name of two townlands in Kilkenny, is simply Da-mhagh, two 

 plains ; Eosdama, in the parish of Grange, same county, the wood of the 

 two plains. That part of the King's County now occupied by the 

 baronies of Warrenstown and Coolestown, was anciently called Tuath- 

 da-mhaighe, the district of the two plains, by which name it is 

 frequently mentioned in the Annals, and which is sometimes anglicised 

 Tethmoy ; the remarkable hill of Drumcaw, giving name to a townland 

 in this locality, was anciently called Druim-da-mhaighe, from the same 

 district. We find Glendavagh, the glen of the two plains, in the parish 

 of Aghaloo, Tyrone. 



The valley of Glendalough, in "Wicklow, takes its name from the 

 two lakes, so well known to tourists ; it is called in Irish authorities 

 Gleann-da-locha, which the author of the Life of St Kevin translates 

 Yallis duorum stagnorum. In the parish of Kildysert, Clare, there is an 

 island called, from its shape, Inishdadroum, the island of the two drums, 

 or backs ; the same form has given name to Inishdavar, in the parish of 

 Derryvullan, Fermanagh ; to Cornadarum, Fermanagh, the round hill of 

 the two ridges ; and to Corradeverrid, in Cavan, the hill of the two 

 caps ; Tuam, in Galway, is called in the Annals, Tuaim-da-ghualann, the 

 tumulus of the two shoulders, evidently from the shape of the ancient 

 sepulchral mound from which the place has its name. 



Desertcreat, a townland giving name to a parish in Tyrone, is men- 

 tioned by the Four Masters as the scene of a battle between the O'Neills 

 and the O'Donnells, in A. D. 1281, and it is called by them Diseart-da- 

 chrioch, the desert or hermitage of the two territories ; they mention 

 also a place called Magh- da- chairneach, the plain of the two earns; Magh 

 da-gabhal, the plain of the two forks ; Ailiun-da-bernach, the island of 

 the two gaps ; Magh-da-Chainneach, the plain of the two Cainneachs

 mentioned in the Annals. 



There is a townland in the parish of Eossinver, Leitrim, called Lis- 

 darush, the fort of the two promontories ; and on the side of Hungry
