A Comparison of the Soot-Fall in Knoxville

A survey of the soot-fall in Knoxville was made during the year 1927 by Martin F. Quinn and Albert H. Cooper while working on their theses et The University of Tennessee. At that time no important effort had been made to decrease the smoke produced in the city. However, in 1928 a Smoke Abatement Bureau was established. After months of active work, chiefly in the industrial plants, it was thought desirable to find out what effect, if any, certain isolated reductions in smoke had had on the general average of soot-fall.

With the object of obtaining this data, a second survey was started February 1, 1929. The results of the two surveys, together with certain related meteorological data for the two periods, are presented on the following pages.
