Typical Potato Seed Balls 



The print above shows potato seed balls such as Luther 



B urban k, in his boijhood, found. The potato has become so 



accustomed In 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 connection with the present, 



and grow into potatoes which hark back to the 



long-forgotten traits of old heredity.
