BONES, THEIR VALUE AND USES.
Interesting Facts Obtained From Visit
to Brooklyn sugar Refinery.

A Brooklyn Eagle reporter, who
visited one of the big sugar retineries
in the Eastern district not long ago,
was amazed TO see what an important
part animal char or bone black, plays
in sugar publication. Tons and tons
of the stuff are in constant use, being
burned over and over in huge ovens.
The thought occurred to him that
very few people associated the awful
smells which float over the Manhattan
beach tracks from Barren island with
the white, sweet crystalization which
is in daily use upon their tables. He,
therefore, determined to utilize the
first opportunity he lad to find out
something about bones aud what uses
they are put to. The chance came
one dav last week, when he met down
at Bay Ridge man who had formerly
been foreman OF a bone-boiling estab-
lisMncnt.

care the fresh ones from slaughter
houses and butcher shops, and bone
boilers made special effort to collect
such. The best quality of bones are
shins, thighs and forelegs, and these
are rendered out to free them from fat
and flesh, and sold for manufacturing
purposes. Shins, properly cleaned,
will bring $40 ton, while thighs are
worth $50 ton. Fore legs are cheap
at $50 ton. The makers of knife,
umbrella and parasol handles, collar
buttons, toothbrushes, hairbrushes,
buttons, and all kinds of things in
which bone can be used buy all of these
that they can get. Toothbrushes are
mostly made from thigh bones, while
the bones used for buttons and parasol
handles are, as general thing, shipped
to Europe to be made up. Sheep bones
make excellent fancy parasol handles,
and ivory fans which society bellies SO

one would think. In fact, the leg bone
of a sheep will take finer polish and
is less brittle than that of a cow or
steer"

Where do you get bones?"
''As | have said, we make a busi-
ness of collecting from local establish
ments, but the amount thus obtained
wouldn't keep us going very long, SO
we have them sent in from all over the
country. The western slaughter
houses supply the greatest quantity,
as so much of the cattle-kiliing of the
country is now done out there. Bones
for fertiizing we boil in open kettles,
but those for boneblack are put in
air-tiYht tanks and boiled under pres
sure. for by this process the nitrogen
is eliminated and carbon, the part
wanted, is left"
'.Do YOU get anything else from
bones besides bone black and material
for manufactured"
"Oh, yes; neat's-foot oil is extracted
from the shins and hoofs of cattle, and
the liquor which is left over after boil
ing makes good sizing glue for the
paper manufacturers. The best bears
grease, too, is made from the marrow
of fresh bones"
"Do the ragpickers supply you with
many bones?"
"Of course, we take the stuff they
fish out, but naturally it is of inferior
quality and doesn't begin to compare
with the fresh stock. VIII l have
something with you? Don't mind if
do. About two fingers of pizen will
