THE FOOD WE EAT.
EXCELLENT DYES EXTRACTED FROM
FOOD PRODUCTS.

Uncle Snm VIII show Specimens Of
White silk Dyed With These Ex.
tracts at the Pan-Americnn-Che
icals and Good Roads.
I \ few years ago the adultcration OF
food became so general as to cause
wide alarm, and Il crusade was insti,
tutcd against the practice which I'M
pcrilcd the health of the nation. Leg
islaturcS were appraised of the dangers
and stringent laws for the suppression
of food adullcration were passed
Great good was accomplished, but the
evil has not yet been entirely wiped
out, and the agitation must continue.
There must be n wider spread of
knowledge regarding the food we eat
before the beginning Of the end of the
practice Of adultcratiOn comes in sight
The importance of the exhibit to be
made in the Division of Chemistry OF
The Department Of Agriculture of the
United States Government at the Pan.
American Exposition can hardly be cs
timatcd. In this exhibit will be show II
pure foods and food adultcrants.
There will be displayed in an attract
i've form the principal typical manufac'
tured foods in a state Of purity. Each
of the exhibits will be accompanied by
analytical data showing the compost
ton and nutritive value of the sample
In connection with these will be illus
trated the principal adultcrated forms
of these foods, accompanied with a
statement showing the nature Of the
adultcrant and the amount thereof con.
tanned in given quantity of food.
The principal adulterants employed
will also be illustrated in bulk with
statements showing their properties
and the dangers Of their indiscriminate
use.
The principal adulterants illustrated
will be preservatives and cOloring mat
tiers, and in connection with cOlOring
matters skeins of white silk will be
shown colorcd with the dyes extracted
from food products This exhibit will
not only be typical Of manufactured
and ndulterated foods, but will also he
educational in showing the character
of these foods and their value as nutri-
ents.
An illustration Of the beet sugar IN.
dustry of the United States will be
given A large map will show by shad-
ed areas the parts Of the country best
suited to the growth Of sugar bects
with high content Of sugar. This
map will also show the locations Of eX,
listing sugar factories as well as the To-
cations Of those which are In process of
building or projected.
The exhibit will consist Of samples of
products from the various factories of
the United States, showing all products
from the perfect beet to refined sugar.
An illustration will also be given Of
the byprOducts used for cattle food and
the various forms in which the refuse
of the beet factories Is employed fol
that purpose.
In conjunction with this exhibit will
he II complete representation of all the
apparatus employed for the analysis
of hrr,s for determining their richness
In sugar and for the control OF the fac,
tory operations.
This rXlihi; VIII be 70 Il certain rX,
tent retrospective, showing the differ
ent FERNS of apparatus which nave
been employed from time to time. 1t
will also contain. however. all the lat
est improvements in forms Of lnbora-
tory apparatus and Appliances for the
study of the sugar beet
Statistics in II convenient tHhulir
form will also be shown representing"
the possibilities Of the industry and It's
present magnitude. Photographs OF all
the leading beet sugar factories will
he exhibited illustrating the methods
of construction, field operations and
factory progress.
There are at the present time 10 beet
sugar factories IN the United States
representing SlIoOO.uoU Of capital. AID
the output Of sugar annually IL about
-OO. 600 tons. worth SlDOOO,UOO.
The third section of tie cAhihlt Of
the Chemistry Division viii he His
trntlvc Of the physical ;,d chemical
constitution of the materials used in
the construction Of reads. The impor.
lance of good roads to the l.ogr"S. If
agriculture IS universally ahnittcd, and
tie Secretary of Agriculture las lately
established in the Division It themts-
try Il Road Material Lahoratrry,
The object of this work is To deter
mine by careful chemical and physical
tests the composition Of the materials
best suited to the manufacture of good
roads. The exhibit will consist of the
road materials en- bloc. together with
the results of artificial attrition. The
fine dust obtained by this process is
nodded into cubes under great pressure
and then subjected to the blows of Il
small hammer until diSintcgratcd The
cubes Of these materials will be cXhIb-
tied. together with the fragments OBJ
tanned by their disaggrcgation under
blows of Il given magnitude The chem
ical composition of these materials is
also carefully studied and will he
shown in appropriate tables.
From all these experiments the CO.
efficient of wear is calculated. thus
showing the utility of the material in
question for the construction of Il ,li-
rable road.
1t is believed that this exhibit will
be unique in character and not only of
great interest to those who believe in
good roads, but also attractive and in
structive to the public at large.
