Account of the Gold and Silver Mines of Hungary. 19 
ers, perhaps twenty-four in number, alternately raised by cogs, 
placed spirally round a cylinder which moves behind them, fall 
perpendicularly, and in constant succession, upon the ore so 
placed in the trough. The water passing through the trough car- 
ries with it the particles separated by the operation of the stamp- 
ers on the ore, and, being conducted through a number of small 
winding channels, has time to deposit them before it runs finally 
away; the smallest being suspended till they reach the extremity 
of the canals, whilst the larger are deposited sooner. The whole 
is then easily separated, according to its fineness and weight, and 
is taken to a set of inclined planes, each about ten feet long by 
four broad, having boards set edgeways at their sides. Above 
each is a trough in which the ore is put, and into which a gentle 
stream of water is made to fall, and which passing on carries with 
it the pounded ore, and running softly down the inclined plane, 
over the whole surface of which it is spread, deposits the parti- 
cles equally ; but, being nearly uniform in size, those which are 
left nearest the top are the richest. During the whole time a 
man stands by, and with an instrument of wood, like a rake 
without teeth, gently moves the surface of the last deposited 
matter, that it may thus again be exposed to the action of the 
water, and any of the lighter particles may still make their 
escape. When the quantity collected on these inclined planes 
covers the whole about eight inches deep, it is divided into three 
parts; that which is nearest the top being the richest, that at 
the bottom the poorest. The whole is then removed with 
shovels into three separate heays, and each undergoes the same 
process three times. The different portions are now again sub- 
mitted to the assay: the richest are sometimes found to con- 
tain six or eight loths the centner; and if any is so poor as not 
to contain two, it is carried back to be mixed with the ore un- 
der the stampers, but the richer parcels go to the smelting- 
house. < 
Ores which are sa disguised by clay as to prevent the sorters 
from judging of their value, are previous to their undergoing the 
before-mentioned processes thrown into troughs having grate- 
ings in their bottom of different degrees of fineness. They are 
kept in constant motion by women, who use wooden shovels for 
the purpose, whilst a stream of water running over the ore washe 
the smaller pieces, together with the dirt, through the first 
grating into the next; and so on through ‘several troughs, by 
which the whole become separated according to size, the water 
finally carrying off all the earth and finer particles. But this is 
not suffered to run waste, It is conducted through a long suc- 
cession of canals, where it forms its deposits as in the pochwerk. 
The larger pieces are then returned to the sorters, and classed
