When they have landed a good quantity of this Cala- 
mine, which is done by winding it up in Buckets from 
their Works, they carry it away to the places where 
they walh, clean or bud die it, as their Term is, which 
they perform after this manner. They enclofe a fmali 
piece of Ground with Boards or Turfs, through which a 
clear Stream of Water runs ; within this Enclofure they 
Ihovel their Calamine with the reft; or the impure and 
earthy parts and thefe impure and earthy parts the 
running Water which comes in at one end of the En- 
clofure carries away at the other end, and leaves the 
Lead, and the Calamine, and the other heavier {tony 
and fparry parts behind ; and for the better cleanfmg or 
huddling the Calamine while it is in this Enclofure, they 
often turn it, that (6 the Water paffing through may 
wafli it the better ; When they have thus waflied it 
with this running Stream as clean as they can, having 
rak'd up the bigger parts both of the Lead and the 
Calamine, they afterwards put the (mailer parts, that 
they may loft none of their Ore, into Sieves made of 
ftrong Wire at the bottom ; and thefe Sieves, with the 
Calamine, Lead, and the Remainder of the earthy, fpar- 
ry and flony parts which the Water could not waffa a- 
way, they often dip and ftiake up and down in a great 
Tub of Water, by which ftaking of the Sieves, the 
parts of the Lead which is mixt amongft the Calamine 
fink or pitch down to the bottom of the Sieves, as be- 
ing heavieft; the parts of the Calamine in the middle, 
and the other fparry, ftony and traftiy parts rife up to 
the top, which as they rife, they skim off, and throw 
among the reft of the Rubbiih, and then they take off 
the Calamine, and after that the Lead. When they 
have thus cleanfed the Calamine as well as they can, it 
being not yet clean enough, they are forc'd to fpread it 
upon a Board, and fb pick out with their hands the traih 
and (tones that remain. I cannot tell whether you will
