A CoRN-FiELD Experiment, 1906 
Precautions preliminary to a large field experiment having been 
thus taken, and injury to the seed thus guarded against, the way was 
open to a practical test of the most promising of these repellents, to be 
made by planting parts of the same field with corn treated with each 
of them, leaving other parts untreated as a check.
