what manner it has fince defcended, we have no 

 information. 



On a bank not far diflant, there w&s formerly a 

 Britilli fortrefs called Caftell Cymmer, The Cajile of 

 the Confiux. This was demolifheti about the year 

 1 1 13, not long after its erection, by the fons of 

 Cadwgan ap Bleddyn, on fome difagreement with 

 the founder j and it is fuppofed to have never been 

 r-ebuilt *. 



Returning from the abbey to the road, I croffed 

 the bridge at Llanelltid, and proceeded along the 

 vale leading towards Tanybwlch. The firfl v/aterfall 

 the guide brought me to was 



Rhaiadr Du, 



The Black Cataract. This, as I have before faid, is 

 m the grounds of W. A. Madocks, efq. at Dolme- 

 lynllyn, whence it is often called the Dobnely7i!lyn 

 Fall. — The water foams, with a thundering noife, 

 down two rocks about fixty feet high. The fcene 

 has a fmgular appearance from the black adjacent 

 and uncouth rocks being in many places covered 

 with a pure white lichen. The trees on one fide of 

 the ftream had been lately cut down, but the lively 

 and varied green and brown tints of the other were 

 beautifully contrafted with the almoU jet black rocks
