1this is laid as much pure lead ore as the
heap can bear; then the charcoal is
kindled, and when the wind blows, it fans the fire so that the ore is smelted.
In this wise the lead, trickling down from the heap, flows on to the level and
forms broad thin slabs. A few hundred pounds of lead ore are kept at hand,
which, if things go well, are scattered over the heap. These broad slabs are
impure and are laid upon dry wood which in turn is placed on green wood
laid over a large crucible, and the former having been kindled, the lead is
re-melted.

The Poles use a hearth of bricks four feet high, sloping on both sides and
plastered with lute. On the upper level part of the hearth large pieces of
wood are piled, and on these is placed small wood with lute put in between;
over the top are laid wood shavings, and upon these again pure lead ore
covered with large pieces of wood. When these are kindled, the ore melts and
plastered with lute. On the upper level part of the hearth large pieces of
