Bachelors Theses

Abstract

"The chief allegation made by many of the complainants sic in the vicinity of the zinc smelters is that the emanations from the stacks are detrimental to the yield of the crops, especially Sweet Potatoes and Cotton. They claim that on account of the leaves being burned or bleached, the entire plant is poisoned and weakened and the yield is thereby reduced. It was even claimed by some that the presence of the smoke in the atmosphere around the plant has a weakening effect in that it is cumulative, and, while it does not always visibly show, yet the general tone and conditions of the plant are weakened greatly. This contention is quite similar to the theory known as the Invisible Injury Theory"--Introduction, page 1.
