Typical Potato Seed Balls 
The print above shows potato seed balls such as Luther 
Burbank, in his boyhood, found. The potato has become so 
accustomed to being reproduced by the division of its tuber that seed 
balls are now a rarity. And, while the tuber produces 
potatoes true to type, the seed balls, the rarer they 
become, seem to lose all conneclion with the present, 
and grow inlo potaloes which hark back to the 
long-forgotten traits of old heredity.
