 The nearer we approached the fcene of bufinefs, the more penetrating was the fume of 

 thefulphur; but we had very foon too many objefts of attention to regard this incon- 

 venience The mountain is about a mile in length, and is the property of Lord Uxbrid<.e 

 and the Rev. JVIr. Hughes, and the fortunate difcovery of the copper took place a little 

 more than thirty years ago; thus converting a piece of ground, originally of very little value 

 into one of the mod profitable eftates in the kingdom. ' 



The fubftance of the mountain being ore, the work is carried on in a very different manner 

 from the cuftom of other mines : here are, comparatively, few fliafts or levels, the greater 

 part being quarried out, fo as to leave .a vaft excavation open to the day. There are two 

 of thcfe quarries or mines, which are worked by tw.o different companies : the firff goes bv 

 the name of the Mona Mine, and is the fole property of Lord Uxbridge ; the o^her cnlled 

 the Parys Mine is (liared between the_ Earl and Mr. Hughes. The view down this fteep 

 and extenfive hollow is fingularly flriking. The fides are chiefly of a deep yellow or dufky 

 flacc colour, ftreaked however here and there, by fine vefns of blue or green fiiooting 

 acrofs the cavern, mniglcd with feams of greyifi, yellow. The bottom of L pit is bv ,"! 

 means regular, but exhibits large and deep burrows in various parts, where a richer vein h s 

 been followed in preference to the reft. Every corner of this vaft excavation refounds wiih 

 the noife of pickaxes and hammers : the edges are lined with workmen drawing up the ore
