An attempt was made during the summer of 1930 to check results claimed by Christofleau, Vincent, and others relating to the effect of atmospheric electricity on the growth of plants. The results were negative. During the course of these experiments, it was found that, except during the very driest part of the summer, the fair weather current was upward, a result which directly contradicts the work of other investigators in other parts of the world. No accurate comparison could be made with Simpson's value or the total currant between earth and air on account of the type of apparatus used.
