of Water below the furface, and fo waving it to and fro, all 
the lighter and loofer matter is feparaced from the Metal. 
TheFurnaee is fix feet high, four feec wide, and two 
feet thick. Made of Brick ; having a hole in the midft of 
the top eight inches over, growing narrower towards the bot- 
tom of it, where, on the fore part, ic ends in a finall hole, 
environed with a femieircle of Iron to keep the molten Metal 
About the middle of the Back, there is another hole to receive 
the Nofeof a great pair of Bellows, requiring continually the 
ftrengch of two lufty men. 
The night before they begin, Charcoal is kindled in the 
Furnace to Anneal it ; and when it is hot, they throw two or 
three (hovels of Coal, to one of the forementioned ScufF,and fo 
proceed during the whole Work,making^r^^«»? [uper JlratHm 
of one and the other* After eight or ten hours the Metal be- 
gins to run ; and when the Receiver below is pretty full, they 
lade it out with an Iron Ladle, and caft ic into Sows in Cavities 
or Forms made with Aflies. 
They frequently flop the paflTage^hale with Cinders to keep 
in the heat; and when they think a quantity of Metal is mel- 
ted, they unftop the hole to pafs it off. 
If the Stuff be hard to flux^ they throw in feme Jla.g (which 
is the Recrement of Iron) to give it fufion* Their Irons melt 
away apace, wherewith they proak out the Cinders from the 
hole. 
A ftinklng blue fmoak proceeds from the Furnace, and all 
by-ftanders put on the colour of dead men* The workmen 
muft be well lined with OyI,Sack,Strong Beer,and goodViftu- 
als: for the Work continues three days and nights without 
intermifliOD, ufing no other variety, than above faid. 
Alarge Cavity will be made in the Furnace : for the Me- 
tals or the Fire, or b3th together corrode and wear the great- 
eft part of the bricks away. 
To get the Silver from thefe Metals, they now ufeno other 
Art, than that of the iVy?. 
To Refine their Copper from the Litharge, they formerly 
laid their Ingots of Lead and Copper on Loggs of Wood fired, 
which would eafily melt down the Lead or Tinn, and fo leave 
the Copper full of holes wherein the Lead had been lodged. 
But now they commit this work alfo to the TV/?.
