Mr. Edison's carbolic-acid plant was being supplied with the raw
material.

And then it was believed that America could not make dyes to take the
place of those which came from Germany. All the United States, it was
said, would have to wear white stockings. The country just could not
produce the dyes necessary, and the product of the American plants was
inferior. But America could make the same dyes. She is making them.
Right now she is making practically as great a variety as Germany ever
sent over here.

A few miles outside of Philadelphia, at Marcus Hook, on the busy
Delaware river where the ships of the world are being made, the Benzol
Products Company turns out large quantities of aniline oil. The aniline
oil, the essential basis of aniline dyes, is made into tints as fair and
perfect as any the wizards of Germany ever conjured out of their test
tubes.

The tale about America's inability was proved to be a fable. The Marcus
Hook plant is one of three which sprang up when the war began. Others
are the Schoellkopf Aniline and Chemical Works at Buffalo and a third is
the Becker Aniline and Chemical Works at Brooklyn. The three are now
merged into one great operating company and Germany will have some
difficulty in getting back her dye trade when she is ready to again
fight for the world markets.

Moreover, the world-famous duPont Company, which has made powder and
chemicals for all the nations, turned in and purchased the Harrison
Chemical Works in 1917, and besides making "pigments" has entered the
coal tar dye industry. The company made an intensive study of the dyeing
industries--cotton, calico printing, wool, silk, leather, paper, paints,
printing inks, &c., and made plans to meet the requirements of each. The
Harrison plant is but one of the immense group operated by the duPont
Company and it has been famous for the manufacture of white lead and
acids.

A CHEMICAL DISCOVERY.

There is in fact no line in which the chemists of America did not rise
to the emergency and the "romances of the industrial" world are not more
entrancing than are those of the medical and other fields. Chemistry,
for instance, discovered an antitoxin for the deadly gangrene, or gas
bacillus, poisoning of the battlefields. The discovery was made by
research workers in Rockefeller Institute.

It is one of the most important discoveries in medical research as
applied to war, having an even greater bearing on the treatment of war
