THE IRVON. THE LLYNVI. THE TAF. 113 



THE IRVON. 



The least known (to Englishmen) of the Welsh 

 rivers, are by far the most worthy of name and 

 acquaintance. The Irvon is, probably, as little 

 familiar to the summer visiters of Wales as any 

 foreign stream not commercial, yet in its course of 

 about twenty-five miles, ere it falls into the Uske 

 near Builth, few routes conduct us through so 

 many charming scenes. Every mile of this course 

 is such as Walton would have deemed worthy of 

 commemoration by a song. The Irvon, receiving 

 the Chwernwy, theDylas orDulas,and other streams 

 from the north, forms the channel through which are 

 poured nearly all the superfluous waters of that part 

 of the county lying northward of the Eppynt Hills, 

 and joins the Wye a little above the town of Builth, 

 after a course of about twenty miles. 



THE LLYNVI 



Has its source above Savaddan Lake, and flows 

 into the Wye near Pipton Chapel. 



THE TAF 



Is formed by two streams, called Taf Vawr, and 

 Taf Bechan, which descend turbulently and precipi- 

 tously from the beacons of Brecknockshire, over 

 limestone precipices, and unite on the southern 

 border of the county near Merthyr Tidvil. Good 

 at some distance from Merthyr> in the spring of the 

 year.
