who made a sign to him by pouring milk into a stream, which after 

 that was called pionn^laipe, i. e. the White Stream, anglicized Fing las. 



Suck [Sue] — The River Suck, in Irish Sue, which makes Suca in 

 the gen. singular and nom. plural ; for we are informed that there were 

 three Suca, which sprang up between the lands of Gal way andEoscom- 

 mon in the time of Eremon. The Three Sues are the one which bears the 

 name at present with its two tributaries — the Sheffin and the Eiver of 

 Clonbrock, in the county of Galway, and in their united form they fall 

 into the Shannon at Shannon Bridge. In a MS. in the Library of the 

 Royal Irish Academy, C. 28, p. 1, the word Succac, which is evi- 

 dently from the same root with Sue or Suca, is explained by a gloss 

 thus : — Succac .1. cpeun no pogluaipce, suecat, i. e. powerful or 

 quick in motion. The word cpeun, powerful or forcible, would be ap- 

 plicable to this river with its impetuous and swift-flowing current. 



Sum [Siuip].— The Suir, the JSTore, and the Barrow. The Suir, 

 in Irish Siuip, Gen. piuipe, is one of the rivers that began to flow in 

 the reign of Irial, son of Eremon, a. m. 3520. The name of this 

 river means a sister ; and probably from this the three rivers here given 

 have been called by several writers The Three Sisters. This river 

 rises in the Devil's Bit Mountain, and unites with the Barrow at 

 Comap na cepi nuipcce, or the Meeting of the Three Waters, about a 

 mile below Waterford. 



Swilly [Suileach].-— The Eiver Swilly falls into Lough Swilly at 

 Letterkenny, in the county of Donegal. In the Annals the name of this 

 river is written Gbainn Suileach, which signifies the Willowy River, 

 from puil, the willow or sally tree, and is the name of the letter S 

 in the Irish alphabet. In the parish of Gartan, and not far from this 

 river, is a lake called Loc beacac, which means the Birch Lake. 



T. 



Toeagh [Copcac]. — The River Toragh, in Irish Copcao, 'which 

 unites with the Eiver Blackwater near Youghal, signifies the fruitful or 

 productive river, probably from the large quantity of fish found in its 

 waters. 



U. 



Uinsion [Umnpion]. — In the time of Eremon the Three Lhnn- 

 piona, or Uinsions, began to flow in the present barony of Tirerroll, in 

 the county of Sligo. The word umnpion is the name of the Ash tree, 

 which in modern Irish is written puifipion and pumnpe6;5, and no 

 doubt but those rivers were named from the Ash tree woods which grew 

 along their banks. These rivers, it is said, are not now traceable, except 

 one of them be the river which runs along the Union Wood, in Irish 

 Coill na h-Un^ion, to the east of Collooney, in which the Ash naturally 

 grows in abundance. There is a river called the River TJinnsion in the 

 barony of Fermoy, county of Cork, and I am informed by Mr. Long 

 that the Ash grows abundantly in the valley along its banks as an indi- 

 genous tree.
