made into coin, fine OF impaired bars
The bullion fund established by Congress
is sufficient to pay down for any deposit
for coinage as soon as the assay value is
known; but bars are usually made from
the same bullion received at the Mint
or, in other words, the depositor gets
back the same bu ion he deposits, but in
fine or unparte bars, with the United
States stamp and value placed thereon.
The process of making coin begins
when then the receiving and weighing
clerk receives and weighs the deposit
and passes it to the Treasurer, who sends
it to the deposit melting room for melting
and assay. The value of the deposit is
thus established and receipted for by the
! Treasurer. The Treasurer (who, by the
way, is the big man of the Mint receipts
| for all bullion and takes receipts from the
| Chiefs of all departments that it passes
| through in its transformation into coin.
| The bullion then passes to the ingot melt
ing room for granulation. This is done
by dropping the molten bullion into cold
water which forms it into irregular small
pieces, the better adapting it to the sub
sequent treatment. These granula-
tions are then passed to the re-
tinery for separation. This process
in short is the dlsolving of the silver, and
destruction of the base metals by boiling
in sulphuric acid for six or eight hours, leav-
ing the gold in tie form of fine yellow
sand. The silver is then precipitated, by
hIinging the solution in come ;tion with
copper, which in time precipitates the
silver in granular form and takes up the
copper. TniS solution is submitted
to further process which precipitates
the copper and makes 1t into blue stone.
After granulation the fine gold and fine
silver is each melted separately, in order
to ascertain their exact nneness, and are |
then melted with the alloy added, and |
run into ingots. The next process the in !
gots are turned over to the coiners de- |
partment taking their legitimate course
in getting there. Here they go through |
all sorts of processes and assume innu-
merable shapes. They are fist passed
through an immense pair of rollers, and
by the way, these rollers are said to have
cost -, 500, and are made to last thous-
and years. The frame that holds them
cannot be broken, and they are of hard
ened steel and will not wear out From
the shape of bars or ingots the metal as
the form of long thin strips, and
the passage throu III the rollers continued
until The strips are nearly as thin as It.
quired for cutting into blanks for coin
They are then cut the proper length.
placed in long copper canisters made tight
with potter clay. These are put in fur
mace and heated all they will bear with
out melting; when taken out they are
cooled in water containing acid. This is
called annealing, and its object is to soft
IN and make more malable, as well as
clean the strips for the next process,
which is passing them through the draw
bench to reduce them to the exact size re-
luired for punching or cutting into I
blanks. This is done by passing the &
strips under a mach ne SO arranged as to {
ut out a round piece of the size required {
or the desired coin. These blanks are i
ent to the adjusting room where each y
,iece is weighed and those too light +
re thrown one side for rernelting, and t
hose too heavy are filed down to
