Upper part of stigma, showing the delicate hairs that cover it. Enlarged. (Original.) unites with the egg cell, which has been formed within the ovule. This constitutes the act of fertilization. But one grain is required for the fertilization of each ovule. The fertilized ovule immediately begins to grow and together with the surrounding ovary, forms the kernel of corn. The silks at the butt of the ear are the first to appear and the first, as a rule, to be pollinated. The mid- dle kernels are next. The com- plete fertilization of the tip kernels of the ear depends upon the continuance of good weather and the late tasseling of other nearby stalks in the same field. Warm, balmy weather, with a slight breeze, is ideal for the transfer of corn pollen. Dashing rains at this season of tne year wash the pollen from the tassel, and a moist atmosphere pre- vents the grains from floating about. The developing kernel is fed from within the cob by a single fibro-vascular bundle which ex- tends directly to the stalk. This duct, in its course through the cob, passes between the soft white cellular pith and the woody portion and enters a passage-way through this woody portion to the base of the kernels. The Dracts about the base of the ovary become the colored chafif of the ma- tured Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustra
