“ manner: Thus they continue to cre& a Pile of 
ic thcfc Logs of Wood, by Layer upon Layer, and 
<£ plaftering each with their Pafte of A flics, till they 
“ are all expended ; when their Pile is often as 
“ high as a Houfe. This Pile they fet on fire with 
“ dry Wood, and burn it as vehemently as they 
“ can ; increafing the Fire from time to time, till 
“ the Afhes begin to be red-hot, and run in the 
“ Fire. Then they overfet their Pile with Poles, 
<£ as quickly as they can; and while the Afhes are 
“ hill hot and melting, they beat and clap them, 
“ with large round flexible Sticks made on pur- 
<£ pofe, fo as to incruft: the Logs of Wood with the 
“ Afhes ; by which the Afhes concrete into a folid

All the Pot-afti we have from Ruffla, Sweden P 
and 'Dantzick is exa&iy like what our Author here 
deferibes, and feems to be made in this manner. It 
is, however, generally obferved, that the Ruffian is 
the beft of thefe, on account of the greater Quan- 
tity of Salt in it. Now if, in the preceding Procefs, 
we make our Pafte of the Afhes with Lye, inftead 
of Water, it is plain the Pot-afh will be impregnated 
with more Salt, and make all the Difference there 
is between thefe Sorts of Pot-afh. This then is 
likely to be the Pra&ice in Ruffin \ where their
