AGfelCUtfURS. 75 



jwoaches this country from Shrewsbury, a line of highly Improvement 

 elevated ground presents itself to his view, extending from 

 near the Severn to the neighbourhood of Wrexham. This 

 ground once formed the ^rampart of Wales, though now 

 cultivation in several of its parts is softening the roughness 

 of its aspect. 



The continuity of the line of hills is broken by two prin<* 

 cipai valleys; the larger is that of Llangollen, through 

 which the Dee flows : the other is watered by the stream of 

 the Ceiriog. One part of the Bron-y-garth enclosure looks 

 over the last-mentioned valley, and has a northern aspect; 

 the other looks to the east, over the plains of Shropshire. 



Lime is found in every part of the line which divides the 

 mountains from the plains, on the frontier of North Wales. 

 The beds of lime-stone in some places lie on sand-stone, 

 and in other places are found below it. In others again the 

 lime-stone is near the bottom of a hill, sand-stone occupies 

 the middle space, and lime-stone is again found upon the 

 summit. 



In some respects the sand-stone works well, and is of a 

 Superior quality, as the aqueducts over the Dee at Pontey- 

 syllty, and that over the Ceiriog at Chirk, sufficiently prove. 

 The sand-stone in the quarries, which furnished materials 

 for building these aqueducts, is perhaps equal in beauty and 

 durability to Bath or Portland stone ; and the lime-stone, 

 at least in one quarry near Oswestry, becomes a beautiful 

 black marble. In the lands, spoken of below, the lime- 

 Stone supplied me with .manure, and the sand-stone forms 

 the larger portion of my fences. 



The paper, which accompanies this letter, is drawn up 

 fri haste, because it was only very lately that I deter- 

 mined to be a candidate for the notice of your honourable 

 Society. But all the parfs are faithfully and accurately 

 stated. 



I am, Sir, 

 Your most obedient Servant, 

 RICHARD PHILLIPS.
