ition on Stalk.—If all ears in a field are of approximately uniformheight, there is greater probability of complete fertilization of all thegrains of the ears than would be the case if some of the ears were highup on the stalks, while others were comparatively near the ground. Anextremely high ear tends to late maturity, while one very near the groundtends to ripen extra early; hence the stalks on which such ears are bornewill not make, as a general rule, a very large growth. For the ears ina field to be completely fertilized or pollinated, the silks of the earsshould be ready to receive the pollen of the tassels as soon as it is givenoff. On the same plant the silks usually make their appearance in fourto five days after the tassel. The position of ear on the stalk should be at a medium height, fortwo reasons: (1) because the stalk will be less liable to be blown down,as the ears will have less leverage, thereby averting the injury caused by SOME FACTORS IN SUCCESSFUL CORN GROWING.

Shank.—This should be of sufficient size and strength to hold the earwell and in a rather drooping position, so that rain will be shed andhence prevented from running into the ear and causing the grain to rot,,as would often be the case if the ear were held in an upright position,especially if the end of the ear was not covered well by shuck. Shape.—The cylindrical ear (Fig. 15, 3) is the best type, as it is theone that generally yields the highest percentage of grain to cob and thelargest total amount of shelled corn per acre. The rows of kernels shouldrun parallel the full length of the cob, without change in shape or dimi-nution in size, or, if so, but very slightly. If the ears are taperingtowards the tip, there is a suppression of yield, due to one or
