WORK OF settlnH UP inc chemlcai
exhibit OF the National Research
Council will be begun this afternoon
in the lobby OF the Hotel dupont
and It Is anticipated that the dis
play will be ready for public view
by this evening.
Judging from the size and number
OF the boxes and crates containing
II, the exhibit will be quite elsbor-
ate. The principal feature is a topo-
graphic model. complete in every
detail OF an idealized group Of chem
ical manufacturing plants. The outer
portion OF the model shows the
plants and equipment required for
the production Of some Of the more
important crude materials which
are required by the chemical indus
tries. This includes models Of sui
phur wells. a sulphuric acid plant;
a coal mine with the usual equip
ment for sorting and handling coal.
by-product coke oven with stills
and storage tanks for the various
crude products obtained from coal
tar; a hydro-electric power plant
which supplies electric power
10 a plant for the production Of
nitric acid from atmospheric nitro
gen and also to an electrolytic
chlorine plant from which caustic
soda and chlorine are produced by
the electrolytic decomposition OF
salt; and salt wells which provide
salt fol the chlorine plant
The above group OF plants sur
rounds what may be called the heart
Of the chemical industry. that is. the
plants which produce the intermedi-
ate and finished chemical products.
The group Of buildings representing
the production Of the intermediate
chemicals are situated near the CEN
/ ter OF the model. Radiating from
the intermediate chemical plant are
four separate groups Of factory
buildings. one group represents an
industry for the manufacture OF
dyes; another for explosives: another
/ for pharmaceuticals and medicinals,
and another for var gases All OF
! these four industries use the same
chemical intermediates for the pro-

dyes. war gases. medicinals, or ex

The exhibit will show what tn
chemist has done and may do 10
the American people in war an'
peace.
Invitations have been sent out t.
educational institutions, clubs, or
ganizations. societies and othe
bodies announcing that the exhibi
is open to the public free Of charge
The exhibit shows most interest

poison gases such as chlorine. phos

high explosives. drugs, perfumes
and other synthetic ingredients. al
made from this great industry.

output OF German monopolies.
