this, and the Sesqui- Centennial Exposition
will do great things for American industry,
and especially for industry in Philadelphia.
New hbers are entering into manufacturing
new. oils. such as perilla oil. are on the
market; new feathers. such as tanned kanga-
roo and shark skins new varnishes. made
with tung oil. And this does not by any
means exhaust the list of the new products
which are constantly being introduced
1t may not be amiss to call attention to
some of the things which chemistry has done
for industry since the last great exposition
held in Philadelphia in 1876. Cheap steel,
6y means of the Bessemer and the Siemens-
Martin processes, came in the decade before
1876. while the many alloy steels. such as
tungsten, vanadium, chiane, nickel and
cobalt steel for our exacting modern uses.
came more recently. Cheap aluminium and
radlum We're introduced during this period
but the Welsbach mantes and filaments for
incandescent bulbs are recent
Artificial abrasives for machine work
and grinding and calcium carbide with which
to make acetylene and cyanamide and arti-
fetal graphite are products of the electric
furnace. The fixation of atmospheric nitro
gen by the several methods employed is also
electro chemical, and the manufacture of
, electric storage batteries for our motors etc,
Is also an electro chemical industry and
quite extensively practiced in this city.
lhe making of electrolytic soda and
chlorine is subsidiary operation in paper
mlils as well as self sustaining industries on
n large scale at places like Niagara Falls,
where the electric current is relatively
| cheap.
Artificial silk and the manufacture Of
dyes are not inherently American lines of
manufacture, but their transpanting and
| local growth are logical developments and
should be adequately protected Chiane
tannage of skins and hides is a peculiarly
| fhlladelphia enterprise, and our people
should better appreciate the exact chemical
| and nice mechanical work that is necessary
| to make smoothly glstening kid for shoes
Much work also has been done in rcccn,
years IN making the combustion of gasoline
more effective and. after many failures nnd
fakes, there are genuine assistants for the
economical combustion of gasoline in in
| ternal combustion engines
| 1T would be almost hopeless even to tr,
to give any idea of the progress in the ms,
or the cruder substances or by products tha
| have gradually been utilized, such as boposs.
from the sugarcane. the flax from seed flax
the eyaporated liquor from paper, maxim,
what Is used to tan leather etc There or,
great possibilities for the manufacturers !,
new solvents and cheaper long known solv.
ents that have lately come on the morket
But the manufacturer must investigate nm,
see whether these are cheaper or bette
solvents than the ones he is using for noints
