taken, that the Liquor doth not drain through the Bed?, or 
oucof thcCiftern. Thebeft way to prevent the fame, is to 
divide the Ciftern in the middle by Oaken boards, chalked as 
before; whereby one of thetii may be mended in cafe of a 
defeft. 
The more Rain ''alls, the more, but the weaker, will be the 
Liquor. Thegoodnefs whereof is tryed by weights prepa- 
red for that purpofe. Fourteen peny weight, is Rich, Or 
an Egg being put into the Liquor, the higher it fwims above 
the Liquor, the ftronger it is. Sometimes the Egg will fwim 
near half above the Liquor* 
Within one minute after an Egg is put in, the ambient Li« 
quor will boil and froth; and in three minutes the (hell will 
be quite worne off. 
A drop of this Liquor falling on iheManufaflures of Hemp, 
Flax, or Gotten- Wooll, will prefently burn a hole through it. 
As alfo in Woollen and Leather. 
Out of the aforefaid Ciftern, the Liquor is pumped into a 
Boyler of Lead,about eight feet fquarejcontaining about twelve 
Tuns, which is thus ordered. Firft they lay long pieces of 
Caft Iron, twelve inches fquare, as long as the breadth of the 
Boyler, about twelve inches one from another, and twenty 
four inches above the furface of the fire. Then crofswife 
they lay ordinary flat Iron Barrs, as clofe as they can lye, the 
fides being made up with Brick-work. In the middle of the 
t>atcom of this Boyler is laid a Trough of Lead, wherein they 
put at fir ft a hundred pound weight of old Iron. 
The fewel for boy ling, is N^vp- CaUli Coals. By degrees, 
intheboyling, they put in more Iron' amounting in all to fif- 
teen hundred pound weight in a boyling. As the Liquor waftes 
in boyling,they pump in frefh Liquor into the Boyler. Where- 
by, and by a defeft in ordering the fire, they were w^ont to be 
above twenty days before it was enough. When that is, they 
try, by taking up a rmal! quantity of Liquor, intoaftallow 
Earthen Pan, and obferving how foon it will gather and cruft 
about the fides thereof. 
But now of late by the ingenious contrivance of Sir Nicolas 
Crifp, the Work is much facilitated. For at his Work at 
Debtford, they boy 1 off three Boylers of ordinary Liquor in 
one Week. Which is done, firft by ordering the Furnace
