conclusion as Speschnew in demonstrating that his plants were predominantly free from

In a different type of experiment that was verified at the Hatch Experiment Station in
Amherst, MA 12 , Professor Warner of the Agricultural College of Massachusetts in 1897
replicated the results of European researchers and discovered some new results of his own.

to see if electricity would be a useful form of treatment. He sowed head lettuce over two

The following chart show the results of that experiment.

Interestingly enough, Warner found that the largest heads of lettuce were the ones over the
heads began to be affected by the mildew. This conclusion was the same as Fischer's, with
