 human senses cannot fathom are represented by 

 factors that obviously cannot blend. 



So, after studying the matter over and 

 wrangling about it till their heads ache, the elfin 

 builders give up the thing as a bad job. 



Their germ factors lie in separate piles unas- 

 sembled and incapable of being assembled; and 

 the result is that no provision will be made for 

 fruit in the future plant. In other words the 

 plant will be sterile, and that particular double 

 stream of germ plasm will cease to be per-

 It may be left to the reader's imagination to make
