manufacture. Only about one third Of
the American output of this oil is mo.
cured from cod livc,s.
From September until March The
livcis arc fat aud in the best condition
A buckctful Of livcrs will then weld
about six quarts of oil. Only four
quarts Of this, however, can be made
suitable Tor medicinal purposes; the re-
naming two quarts is of an inferior
quality and is used by curriers'.
From March to juno the livcrs arc
thin and inferior, and will yield only
one half as much oil. Cod liver oil for
medicinal purposes must be made from
livcrs OF fish that have not been dead
over As hours. Fishing vessels on their
long trips to the banks save the fish
livcrs in hogshcnds and sell them to thc
oil manufacturers for 30 cents pcr
buckctiul. From these livcrs an info.
Fior quality OF oil is made that is used
by tanners.
Up TO about fifteen years ago the
most primitive means were used for oh.
tanning oil from livcrs. The results
we're very unsatisfactory, and tho best
portion oil the livcrs was wasted. The
old method was TO expose the livers to
the action of the sun until the oil wa,
dried out. Only small pcrccn tasc of
oil was thus secured, and tho residue
was thrown away as useless. Now
every portion Of the liver is used. Tho
hc'hod Is to put the livcrs into a large
iin-lincd vat having a coil of perforated
steam pipes at the bottom A pressure
81 thirty pounds of steam i, put on the
poi'er' and the steam escaping through
The pcrforations in the pipes saturatcs
the livcrs with hot steam and thus tries
out the oil. In half an hour after
steam is turned On all tho oil that can
he procured by trying. out will have
arisen to the surface. The livcrs, now
termed "blubbcr," will have sunk to
The bottom Of tho vat. The oil is bai,ed
I'll and put into barrels to cool and set
tie, after which it is refined By beinr nj
lowed to freeze till it is of the con-
slstcncy of thick musl, when it is nut

pressed out in a heavy iron press. The
oil that is pressed through tho drilling
is considered rclinod and after being
put up in new barrels OF forty five gal.
ons each is sold to the wholesale
druggists for abcu: thirty six cents per
gallon. From these il passes TO the re-
all druggists, who sell it for s! or 50
per gallon. Running the oil through
charcoal and sand has been tried as a
'ciinlnS process, but it was found TO bc
vastly inferior TO the freezing and press
ng process. Refined cod liver OIL,
when subjected 10 the same temperature
1t which the crude oil was frozen, will

The bubbcr left in the bottom Of the
vat after the trying out is allowed to
work and fcrmcnt for forty eight hours,
md is then pressed. After the pressure
las continued for fourteen hours all tic
oil is secured that remains in the blub-
Der; it is inferior oil Of which there arc
six grades. 1t is worth about twenty.

curriers' in dressing, tanning and color

Tic best quality of cod liver oil
comes from Norway. Il is much clearer
md whittier than the American oil. II

Ions each. enclosed in wooden barrels
The claim is made that no livers except
those of the Goldfish are used in its
manufacture, but American manulac-
Iurers strongly suspect that it owes its
remarkable clcnrness to lis having been
mixed with seal oil. Twenty dollars
per gallon is considered low price for
This oil, and it sometimes goes as high
rs SIS. America is the largest buyer of
Norwegian oil.
Cod liver oil has long been recognized
IS valuable remedial agent, but it i
not generally known that sometimes
when the oil fails to effect cure tho
steam arising from tho frying out watts
will succeed.
