where the production of the plants is likely to be influenced by 
irregularity of stand and by inequalities in germination, soil, and 
growing conditions. The purpose of the present investigation was 
to study the reaction of these types under conditions that provided a 
wide range in the environment, obtained in this case by altering the 
spacing of the plants. The results should indicate their comparative 
values.

LOCATION AND PLAN OF THE EXPERIMENTS. 
The experiments were located at Clarksdale, Miss., at Waco and 
San Antonio, Tex., and at the Arlington Experiment Farm, Rosslyn, 
Va. 
The plan of th<3 experiments was to grow both types of corn at 
different spacings to determine which would show the greater adapta- 
bility, judged by its yield. In the experiments conducted in Missis-
