by-products of the sugar industry in
the present situation of possible
scarcity of stock feed is contained in
an article in the June number of The
Hawaiian Planters Record, which was
devoted exclusively to the food con
servation campaign. The article Is
written by L. ID. Larsen, head agricul.
turalist at the planters experiment
station, and is in part as follows: Ill,
By L. d. Larsen &
In the following outline we attempt
TO enumerate some possible uses TO
which the various by1produets of the
sugar industry may be put and to
point out the possibilities of each. We
do not try to Indicate the most prom.
Using or TO figure cut the most remuner-
alive. The practical application of
each remains 70 be worked out. We
believe, however, that there are posi-
bilities involved which should be con
sidered at time like this. When con-
servation has become necessity
throughout the world, are we utilizing
the by-products of our industry to the
best advantagei
Potnsh From Molasses
The potash alone contained in the
amounts to about 800 tons The
be approximately $2,550,0 900, or under
normal conditions $4,000. Under
normal conditions we import each year
about 800 tons Of potash for fertih.
zer. The potash in our molasses, there
fore, is three hundred tons in excess
OF our annual importations of this ma

extent of nitrogen and phosphoric
acid. III.
y In manufacturing potash from mo.
lasses an additional value may be OBJ
tanned in the form of fuel either direct
or as alcohol. .."..
Alcohol Prom Molrsses ..."r
One ton of molasses will produce
sixty gallons of alcohol, now worth ap-
proximately thirty-six dollars, or sixty
cents per gallon. Under normal con
ditions its value would be 1880, or
thirty-three cents per gallon. Used as
o substitute for gasoline il would be
worth twelve dollars, or twenty cents
per gallon. When properly handled
alcohol is equivalent gallon for gallon
to gasoline. Ns.~ 4
The residual potash left over from
the manufacture of alcohol from one
ton of molasses is eighty pounds. AT
the present market price this would
be worth twenty dollars Under nor
NAL conditions it's value would be
four dollars. ,F."
Fuel From Molasses ~.
i The fuel value of our annual output
Of molaBses is equivalent to q, 500 tons
of coal. "A
y The fuel valve Of one ton of molasses
is 1850 calories This is equivalent to
one ton of bagasse or one-ffth ton of
coal,
The potash contained in one ton of
molasses which could be recovered on
burning is sixty four pounds eighty
per cent recovery. This is worth at
the present market price sixteen dol
lars, or twenty-five cents per pound.
Under normal conditions IL would be
worth 1920, or five cents per pound.
Feed Value Of Molasses
The feed value of our annual output
of mOlasses corresponds to $685. tohs
Of corn. o.. -."
According to feeding experts on the
mainland, the value of molasses for
feeding purposes as compared with
corn meal varies between seventy.fye
and one hundred per cent. On this basis
molnsses at the present time would be
worth from sixty TO eighty dollars
per ton for stock feed. In 1905 Lind
say, feding expert in Massachusetts,
placed the feed value Of cane mOlasses
at $3.50. ..-.at ~
Cane Top Hay ". Il
Cane tops when shredded and cured
produee a hay which is readily eaten
by mules or other stock. Some diff
Guilty. has been experienced in obtain
ing h suitable shredder for cane tops,
but this has been overcome by the
advent of the Searby shredder. If
run at q moderate speed il shreds the
cane tops into strips which are suitable
for feeding, If run at q high speed
the material becomes rather fine for
satisfactory handling.
The food ingredients in the cane tops
from one acre amount TO 1859 pounds
of dry matter, so pounds of digestible
protein, $50 pounds of carbohydrates,
and 30 pounds of fat. -.
The annual importations of hay into
these Islands amounts TO 1921 tons.
The available cane tops amount to-,
$4,000 tons, which, made into hay,
would be 1l2,50O tons. On the drier
plantations, where curing would be /
possible, the annual production Of cane !
tops would be 1922 tons, which !
would produce 50,37S tons of hay. i
