How Everything is utilized by Our Moder
Thrift.

Probably the great slaughter houses
furnish the most familiar illustration
OF the mUdern thrift in the utilization
OF what was formerly considered waste

have been called in. Methods for dying
the refuse and extracting all the greHse
have been developed. he grease goes

The development of the tremendous
aniline color industry is altogether due
to chemical experiment with waste
products. In the dry distillation OF
coal or wood Tor gas, the gas passes
through succession OF washers, which
take out its impurities. These i'm
purities, including ANN ona, carboic
acid, acetic acid, and various nitrop
compounds, were formerly waste, hut
are now separated and used Five Ter
cent Of the coal used In gas MANI
faoture is coal tar, and by experiment,
chemists found that this coal tar,
always regarded as waste residue, CON

dyes.
