years 1882 and 1883 nine factories for
making dye from coal-tar were estab-
l;shed il this country. The business
fourished until the tariff act abolished
the specific duty and took away the
profits, then half of the factories went
out of business. Others kept along as
best they could, but were unable to
compete with foreign labor. In 1874
Germany produced $1,000 worth Of AMI
line, 1878 $4,000 and in 1882 S72, 500
worth of dye. This is only one Of the
many products of coal-tar, which is,

| tories number about 10. 900 women and
several thousand men and children.
The industry originated in Nantes,
France, in 1884, and the best brands in
the world still come from there. Spain
and Portugal send outa cheaper grade.
