is only pra&ifed in Ruffia, Sweden , and other 
Northern Countries, where it has been lately dif- 
clofed by one Lundmarck , who tells us he had 
often made it himfelf, in the manner he now de- 
feribes. This Account is contained in an acade- 
mical DiiTertation upon this Subjed at Aboe in 
Sweden , and was communicated to me by Dr. 
Linneus , Profoffor of Botany at Upfal , as a genu- 
ine Account of this Art 5 which I think has hi- 
therto been generally unknown. 
This Author tells us, “ They have many large 
“ Woods of Beech in Smoland , and other Parts of 
“ Sweden , in want of which they take Alder: Of 
<c thefe they are allowed to ufe only the old and 
<£ decaying Trees for this Purpofe, which they cut to 
“ Pieces, and pile in a Heap, to burn them to Afhes, 
<c upon the Ground, by a flow Fire. They carefully 
ci feparate thefe Afhes from the Dirt or Coals in them, 
<c which they call raking them 5 after which they col- 
tC led them in Baskets of Bark, to carry them to a Hut 
u built in the Woods for this Purpofe. This they con- 
a tinue to do till they have a fufficient Quantity of 
<c thefe Afhes. Then their whole Art follows 3 for 
u which they choofe a convenient Place, and make 
“ a Paftc of thefe Afhes with Water, by a little at 
“ a time, in the fame manner, and with the fame 
“ Inftruments, as Morter is commonly made of 
tc Clay or Lime. When this is done, they lay a 
“ Row of green Pine or Fir-Logs on the Ground, 
“ which they plafler over with this Pafte of Afhes : 
“ Over this they lay another Layer of the fame ftrait 
“ Logs of Wood, tranfverfely or acrofs the others, 
which they plafler over with the Alhes in the fame 
“ manner.
