The Power of Environment
These are typical ears of corn received from a number of middle western experiment stations. They show the wide range of variation due simply to environment and selection. There is the closest similarity as to general form, the arrangement of kernels, etc. But the marked variation in size is noteworthy. Consider the difference in weight between a thousand ears of the largest and a thousand of the smallest here shown. The difference would be notable indeed as measured in dollars and cents-and the moral for the practical corn-grower is obvious.
