except in the Irpn and Mundick tlm^ Is but little. 
The beft Ore is that which is in Sparks; and next to 
this, that which hath bright Sfarr in it. 
As for the Working of the Ore, 'tis thus performed : 
The Scones beaten as before, are brought toaMill call'd 
the Stamping-Mill 3 which goeth by Water, with fuch 
Stampers asPaper-Miils have. The Stones are fo difpofed, 
as that, by degrees, they are waflied into a Lattm hox with 
holes, into which the Stampers fall: by which means they 
are beaten pretty fmall , and by the Water continually paf- 
fing through the Box, the Ore, through its weight, falls clofe 
by the Mill, and the parts not Metalline, which they call 
Gaufalty, are wafbed away by the Water. And thus the 
firfl: feparation is made^ 
Then rbey take that which falls clofe by the Mill, and fo 
difpofeit in the faid Mill, that the Water may once more 
drive it, to make a better feparation of the Caufaf ty. 
Next, they dry it in a Furnace on Iron-p!ate$, and then 
grind it very fine in a Crafing-Mill, with Stones common in 
the Hills of that Countrey* 
After this they re-wafli it, as before , and then dry it a 
littlejand carry it laft of all thus fitted to the Furnace,caird 
by them a Blowing-Houfe, and there melt and caft it^ 
There fwims on the Metal^when it runs out of the Furnace, 
a Scum, which they call Drofs ; much like to Sclag or Drofs 
of Iron^ which being melted down with freCb Ore, runneth 
intoMetraU 
The Caufalty they throw in heaps upon Banks, which in 
fix or feven years they fetch over again,and make worth their 
labour* But they obferve, that in lefs time it will not afford 
Metal worth the painsj and at theprefent noneatalU
