The rule is simply this: Seek Nature's plan 

 and follow it. 



In other words, take a lesson from the bees, 

 and pollenize the flowers somewhat as they do. 

 Bear in mind the essentials of the process, 

 which are the same for every flower. Study the 

 mechanism of each new flower and adapt your 

 precise method to the needs of the individual case. 

 It does not matter just how the pollen reaches the 

 reception stigma, provided it does reach it. 



A very short course of practice will give you 

 the knack of cross-pollenizing, and enable you to 

 enter on a course of experiments that will lead to 

 surprising, fascinating and perhaps far-reaching 

 results — results which may prove to be of time 

 wide and world wide significance. 



— The ferns belong to a conser- 

 vative family; and the penalty 

 of conservatism, whether in 

 plants or in human beings, 

 has always been racial stasis.
