Salt from Sea wa,,r

~-ONS
salt from sea water, or brine. In calling our aten-
ton to the extract our friend says that too little suit to
MEAT hoens deoompoion and adds that this is fact
not generaiy known" We do not feel disposed to dis
pne frieuds assertion in the prt misses n fact we
are rather inclined believe that be is correct Under
the head of Marine Soh, the Cycof lis in speaking
OF the process of manufacturing salt from sea water
says:
Inc most convenient works for the manufacture of
SAT- are constructed in the following The saltern
erected at some convenient place the shore it is
long and low building, consisting of parts called
The Tor ehoCse and tire other the Farmhouse, boiling
house. The forehouse ceive the fuel and cover

nace, and the pan boiler in which made And
IN some places they have pans each end of the
building and the fuel place for the workmen are in the
middle The furnace opens into the house by two
mouths and from these is carried wall to prevent the
ashes from flying to the salt pans and in this
communication between the houses The body the
furnace consists of two char hers divided anoth
er by brick work called tie mid feather, which from
broad base terminates in high edge nigh top
furnace, and by of short pillars of cast-iron fixed
upon it, supports the saltpan The pans oblong and
shallow, the common measure being fifteen feet length,
twelve feet in BREADTH and inches in depth they
are commonly made of plates Of wrought iron joined
geber with nails, and the joints filed strong cement;
and the bottom of the pan prevented bending down,
changing its by hooks fastened strong bars
which placed across it. Sometimes the sides, which
alwa covered with liquid exposed to the air. are
made Of lead, iron being liable to be roded.
Between the sides of the pan and the walls of the boiling
house there walk, five feet broad where the
kmen stand draw the salt. The wood,
