is thus heated, they caft Water upon it, to make it rend, and 
then dig it up with Mattocks. This done, they break it into fraal- 
ler pieces, and put it into Iron-pots, of the fliape reprefented by 
Figure Cs the mouth of the one going into the other. Thefethey

blew flame, fcarce di ;rnable in the day time. This being con- 
fumed , leaveth a blew uuft behind it w^hich the Workmen ob- 
ferve, and mark with woodden pins. This they dig up, and carry 
into the Work-houfe , and put it into great Tubs of Water^where 
it infufeth 24. hours or more. The Water they afterward boyl in 
Kettles , as we do Saltpeter, and put it into cooling Tubs,, 
wherein they place croffe Sticks^ and on them the Vitriol h&QXis^ 
as Sugar-candy doth. 
The Water , that remains after the extradion of jihe Vitrioh 
they mix with an eight part of Urin and the Lees of Wood- 
aflies , which is again boyled very ftrong , and being fet to cool in 
Tubbs , crolTeSticks are likewife placed , and thereon the Allum

In the Water^ w^hich remains afterthe y^i7/^;^, is found aSedi- 
ment , which being feparated from the Water , is put into an 
Oven , . and Wood laid upon it and fired , till it become red,which 
makes th^ Minium y wherewith they paint their Houfes; and make 
plaifter.
