5^ Mr Stanley ""s Memoir on a Cave at Cefn in DenbigsMre, 



it is interesting to the lover of science, from the circunistajices 

 I have endeavoured to detail, 1 shall add a few directions which 

 may be found useful. I have mentioned the bluff ofGalltfaenan 

 as forming a striking feature in the pleasure grounds of Col. Sa- 

 lusbury, on the crest of which has been erected a summer 

 house, connnanding in front a bird"'s eye view of the whole val- 

 ley through which the river Elwy runs, affording at the same 

 time on the left, a partial view of the narrow gorge confining 

 the brook Meirchion, and on the right, the progress of their 

 streams through the aperture supposed to have been formed by 

 the removal of a continued line of rock, connecting this with the 

 opposite cliff of Cefn. From this point, the main opening of 

 the upper cave is not seen, being concealed by the projecting 

 portion of the chff, by the base of which, the road passes the 

 perforated rock forming the lower cave ; but the aperture alluded 

 to as communicating by subterraneous channels with the main 

 vault of the upper cave, appears immediately in front. These 

 features are represented in Fig. 2. of Plate I. 



From Galltfaenan, the real distance, as the crow flies, cannot 

 much exceed a quarter of a mile; but on account of the river inter- 

 vening, which is not at all times fordable, it is necessary to take 

 a circuitous route, either by returning to the main road from St 

 Asaph, down a very steep carriage-road, or by descending a wind- 

 ing path cut by Col. Salusbury, leading to the foot of his cliff 

 near to the mouth of the subterraneous stream, alluded to in note 

 p. 49, which bursts up with a plentiful supply of water, not cer- 

 tainly equal in degree, but similar in other respects, to the reap- 

 pearance of the river Mole near Dovedale in Derbyshire. This 

 path leads to a small bridge called Trap-bridge, over the brook 

 Meirchion, on the high road above mentioned, which runs parallel 

 to the Elwy, and immediately opposite to the west front of the 

 Cefn cliffs, commanding an admirable view of the whole line of 

 stratification, as well as the apertures of the upper and lower 

 caves. The river is crossed at the small village of Pont Newydd, 

 so named from its bridge built by Inigo Jones, whose fa- 

 mily it is said came originally from this neighbourhood. This 

 road, after crossing the bridge, diverges to the right and left, 

 the latter leading towards the great turnpike-road from St As- 

 aph to Abergele, while the other branch turns toward>s the lower
