 IT. growing corn, the two principal ele- ments are heat and moisture and, owing to the fact that the south has the heat over period twice as long as the north, it behooves the south to secure the necessary moisture for the proper culti- NdIioi Ol CO1li MT IodCUH 6Apldu1S HOW the south can get this moisture needed for the growing of corn by certain meth ods of blowing and preparation of the ground, which already have been tested and proved to be the most successful methods of growing bumper corn crop.
 BETTER METHODS

Just as soon as the south learns to do these things properly, it can beat the north in growing corn, according to the belief of MT Bacon i The moving pictures shown in connec- tior with MT. Racons lecture shows the examination and sprouting of corn in soil packed in glass containers, the tiny blades of corn shooting out of the seed to the surface and the roots and tendrils working down into the soil, while the camera recorded each tiny movement.
