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 rif 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 ti[) kernels of the ear depends upon the continuance of good weather and the late tasseling of other nearjjy stalks in the same field. Warm, balmy weather, with a slight l^reeze, 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 fibrorvascular 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 chaff of the ma- tured Please note that these images
