that something could be done about it. By reestablishing a proper soil balance he actually grew crops that contained an ample amount of the desired minerals. This was incredible. It was contrary to the books and it upset everything connected with diet practice. The scoffers began to pay attention to him. Recently the Southern Medical Association, realizing the hopelessness of trying to remedy nutritional deficiencies without positive factors to work with, recommended a careful study to determine the real mineral content of foodstuffs and the variations due to soil depletion in different locations. These progressive medical men are awake to the importance of prevention. Dr. Northern went even further and proved that crops grown in a properly mineralized soil were bigger and better; that seeds germinated quicker, grew more rapidly and made larger plants; that trees were healthier and put on more fruit of better quality. By increasing the mineral content of citrus fruit he likewise improved its texture, its appearance and its flavor. He experimented with a variety of growing things, and in every case the story was the same. By mineralizing the feed at poultry farms, he got more and better eggs; by balancing pasture soils, he produced richer milk. Persistently he hammered home to farmers, to doctors, and to the general public the thought that life depends upon the minerals. REENTER DR.
