upon which they lay Wood , and fet it on fire. When the Stone 
is thus heated , they call Water upon it , to make it rend , and 
then digit up with Mattocks. This done, they break it into fmal- 
ler pieces, and put it into Iron-pots, of the fhape represented by 
Figure C 5 the mouth of the one going into the other. Thefe they 
place , th tone in the Oven upon an Iron fork Hoping, fo that, 
the Stone being melted , it may run into the other , which Hands 
at the mouth of the Oven , fupported upon an Iron. The fe 
running of the Stone is Sulphur. 
The remainder of the burned Stone is carry ’d out , and laid upon 
a high Hill , where it lies expofed to the Sun and Air for the fpace 
of two years § and then taketh fire of itfelf, calling forth a thin 
blew flame, fcarce difcernabde in the day time. This being con- 
fumed, leaveth a blew duft behind it $ which 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 2 4. hours or more. The Water they afterward boy 1 in 
Kettles , as we do Saltpeter , and put it into cooling Tubs , 
' wherein they place croffe Sticks , and on them the Vitriol fallens, 
as Sugar-candy doth. 
The Water , that remains after the extraction of th t -Vitriol, 
they mix with an eight part of Urin and the Lees of. Wood- 
afhes , which is again boyled very ftrong , and being fet to cool in 
Tubbs, crofleSticks are likewife placed, and thereon the A Hum 
fallens. 
In the Water, which remains after the A Hum , is found a Sedi- 
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 the Minium , wherewith they paint their Houfes ; andmake 
plaifter. 
So far this Defection 5 Which gave occafion to a curious per- 
fon to call to mind, That there was a kind of Stone inth z North 
of England , yielding the fame fubftances , except Minium..
