1 being compleated, the fmelters take from the 

 c huts a ladle-full of hot flags, pour them in on the 



* brand, fee upright in the road : and the wood 

 4 generally burning down in a night's time, the 



* ore, if left to itfelf, will continue burnino- for 



* eight, nine, or ten weeks. There is much ful- 



* phur procured at prefent from the Rammelsberg 



* ores, of which the old workers knew little or no- 



* thing, and much more may flill be obtained, by 



* proper management. 



c For inftance, thus the covers of the roafts be- 

 c ing, as is faid, burnt down, they become foft 



* by the great degree of heat *, and then, with a 

 c piece of timber, they are ftuck full of round 

 « holes, for the fulphur, which retires into them, 



* to be ladedout with iron ladles. The vitriol- 



* fmall andittrnel here employed, mould feem to 



* promote*' the caking of the covers, to prevent 



* the more eafy evaporation of the fulphur.' 



Inftead of the above holes, they now make 

 certain fmkings, or pits, about two feet in diame- 

 ter, by a foot and a half deep, which are ftruck 

 firm with vitriol- fmall, and (land afunder the length 

 of one diameter. Now, fhe road burning from 

 below upwards, the fulphur retires into thefe pits, 

 out of which it is laded with iron ladles into moift- 

 ened tubs. It would require no fining, did not 

 fomeof the vitriol-fmall drop into it in the lading, 

 and thus taint the fulphur. The firft fining is per- 

 formed in iron coppers, wherein the fulphur melts ; 

 and after the coarfe, impure parts are funk to the 

 bottom, it is cad in moulds \ what thus remains 

 behind, is in the fecond fining treated like the crude 

 fulphur.
