An Experiment in Corn
The ear of corn shown at the left is one which, on an ordinary corn plant, was allowed to take its course. The other ear is one which was covered with a paper bag at the time when the pollen was flying. The strands of silk thus being protected from pollen, the kernels beneath did not mature. It will be seen from this that the breezes are as necessary to the corn plant as the bees and birds are to the flowers.
