A Field of Sugar Beets
The sugar beet has been developed by generations of very careful selection. Careful chemical analyses were made of different beets, and only those having a high sugar content were used as beet parents. By this means it has been found possible to develop races of beets in which the sugar content is more than one-third the total bulk. The abundance of the crop is well illustrated in the picture.
