Giants and Dwarfs 



These cactus seedlings show amazing variation. Though 

 grown from the same lot af seeds, some of them are mere pig- 

 mies, while others rise to proportions that, by contrast, are colossal. 

 The child is father to the man; and the big children of this 

 lot of seedlings will make big mature plants, while 

 the little ones will always be dwarfs.
