Abstract
The author observed that Phaseolus seedlings grown under glass bell jars which were closed off by water were two or three times as long as those seedlings which were grown under jars without the water closure. It was suspected that coal gas or other impurities were causing these results. Thus, experiments were performed to determine if indeed coal gas was affecting plant growth. Results indicated that coal gas has an inhibiting effect on the growth and length of the seedlings, but it also promotes the growth in thickness. Shortening and thickening was proportional to the concentration of the coal gas and the time of exposure. Mercury vapors were found to produce similar differences in height and thickness of seedlings as coal gas, but they are at the same time lethal to the plants.
