Ifthree stalks is too great a number, one or more canbe pulled out early in the season, and the field thinnedto the number desired. Breeding Field—The field for the highly-bredcorn must necessarily be small. This is true because.

Onthe other hand, a small field will allow all possibleintensive selection. A good sized field for this pur-pose is about an acre. This must be so located as toprevent mixing. As the pollen from corn will float BREEDING AND SELECTION 65 about in the atmosphere for at least a quarter of amile, or farther, it can be seen that this breeding platmust either be located far away from other cornfieldsor protected in some way.
