The beft of them are of a bright fliining Silver Coiour .' 
The next, fuch as arc of a rufly deep yellow. The worft^ 
fijch as have Gravel and Dirt in thea)^ of a raddor Umber 
Colour, 
In the midft of thefe Stones, are fonietimes found the Shells 
of Cockles, and other fniall fiiell Fifhes^ fmall pieces of the 
Planks of Ships, and pieces of SeacoaL 
Th J brighteft of thefe Stones they ufe for Wheel-IockPiflo!s 
and Fufies, 
In Order to the nmk'mg of Qpptr as ^ they make Beds accor« 
ding as the Ground will permic. Thofe at Debtford^ are 
about an hundred feet lopgj^fifieeofeec broad at the lOp, and 
twelve feet deep, flielving all the way to the bottom. 
They ram ihe Bed very well, firfi: with ftrong Clay, and 
then with the Rubbifh of Chalk, whereby the Liquor, which 
drains out of the Diffolutionof the Scones^is conveighed into a 
Wooden fballow Trough, laid in the middle of fhe Bed^and co- 
vered with a Board ; beiog alfo boarded on all fides, and laid 
lower at one end than the other, whereby the Liquor is con" 
veyed into a Ciftern under the Boy ling Houfe. 
When the Beds are indifFerenrly well dryedj they lay on the 
Stones about two feet thick. 
Thefe Stones will be five or fix years, before they yield any 
Gonfiderable quantity of Liquor; and before that, the Liquor 
they yield is but weak. 
They ripen by the Sun and Rain, Yet experience proves, 
that watering the Stones, a! though with Water prepared by ly- 
ing in the Sun, and poured through very finall holes of a Wa- 
tering-pot, doth retard the work. 
In time thefe Stones turn into a kind of Vitriolick Earth, 
which will fwell and ferment like leavened Dough. 
When the Bed is come to per fed ion, then once in four years, 
they refrefli it, by laying new Stones on the top; 
When they make anew Bed, they take a good quantity of 
the old fermented Earth, and mingle with new Stones, where- 
by the Work is haftned. Thus the old Earth never becomes 
ufelefs. 
The Ciftern before mentioned is made cf ftrong Oaken 
boards, well jiyned and chalked. That at Dehtford v^ 'iW coo^ 
tain fcnu hundred Tuns of Liquor, Great care is to be 
taken,
