tons of cherry S, now a source OF
annoyance ant e pense 20 canneries,
can be made tt Vi Ia two valuable oils
and also a mea / feeding cattle, ac-
cording to spe Il sts Of tie United
States departm y Of agric lture. In
addition, 1O5.Ol gallons 4 cherry
juice now waste seeding cherries
can be turned iitC esirable Jelly and
strip, or even into alcohol. A saving
OF these valuable by-products from
cherry canning may make possible the
domestic manufacture of substitutes
for almond oil and bitter-almond oil,
now imported, and at the same time
establish new Industry in the cherry
packing districts Of the North Attain
tic, North Central and Western states.
The specialists. however. have not
yet carried their work to point
where they can say that the convert
ing Of this juice and the cherry pits
would be profitable side industry for
The ordinary or smaller cannery. In
cases where q number Of Gamers are
operating within reasonable distance
Of one another, the specialists, how
ever, believe that the waste products
could be sent to a central cooperative
or other plant at small cost and there
utilized to advantage. Studies, how
ever, are being carried on to deter
mine whether means cannot be de-
yised for making these waste products
profitable also when handled on q
small scale.
Some time ago there was similar In
yestigation OF the use Of peach and
apricot pits for making oils and
meal, and a commercial enterprise
has been established in California for
dealing with these products. The de-
partment has published bulletin on
this subject and also one dealing with
the utilization Of raisin seed from
the seeded raisin industry. 1t was
found that many tons Of raisln seed
had considerable fruit adhering to
, them which could readily be turned
into very desirable raisin strip for
, the use OF confeetioners and others.
: After this pulp had been used it was
found that an oil r-oful IN the arts

/. seed, and experiments are under way

. seed could not BG used 10 advantage

|, The following description OF these
, products, and methods which have
been developed for making them, are
taken from professional paper $50,

Fixed oil From Cherry Pits.
1.-THE kernel of the pit, as long has
been known, contains considerable
quantity of oil investigations re-
Gently conducted show that the oily
constituents Of the kernel can be con.
verted into a fixed oil much like al
: mond oil. and a volatile oil practically
identical with oil OF bitter almonds.
= The residue after these oils are ex-
tracted shows on analysis ingredients
. that may make 1t practical cattle
: feed similar to linseedScake,
: "The fixed oil is the most important
by-product Of cherry pits. It has a
golden yellow color and a pleasant
nutlike taste and odor. In character
II is so closely related to imported al
mond oil that II is believed to pos.
sess similar possibilities in the COM
merciaI manufacture OF drugs, oils
: and soap.
'If the pits of all domestic cherries
{ now thrown away at canneries, and
the pits extracted from imported cher
ries, were processed in this way It is
J. estimated that they would yield 800.
600 pounds Of fixed oil. worth in the
neighborhood Of twenty cents .
: pound. The best quality of this fixed
I oil is extracted from the kernels ii
Q hydraulic presses. The shells of thC
pits are first cracked in a mill and The
y uncrushed kernels separated out witt
t sleeves. The oil is then pressed gu
from the meats. In a laboratory ex
& pertinent the kernels yielded p pc
n cent of fixed oil under a pressure o
1850 pounds to the square inch. Oh
e a commercial scale, however, will
g presses equipped for heating the ker
d nels under pressure, it is believed tina
(. 80 per cent or more can be obtained
The oil also can be obtained by grind
r ing the pits and extracting by mean
q of solvents.
Volatile Oil Second Product.
10 The volatile oil, the second product
: remains in the pressed cake after thu
fixed oil has been extracted by pres
sure or by solvents. The volatile OF

the oil was obtained at the rate 0
nearly one pound for every 100 pound

based on the current prices for tn
