THE SNOWBALL CULTI- 

 VATED AND WILD 



The upper cluster of flowers is the 

 one which is grown for its ball of white 

 flowers. The snowball flowers below 

 are wild, such as grow in the woods. 

 The wild snowball, it will be seen, uses 

 the flowers to attract messengers of 

 pollination to the reproductive mecha- 

 nism which the outside flowers encircle. 

 The upper snowball, however, has lost 

 its power of reproduction by seed, and 

 advertises to us, instead, to perpetuate 

 its race.
