elfln architects are making their plans, it will be 

 possible to re-assort the materials (in building a 

 large nmnber of new structures that we call off- 

 spring of the second generation) j making some 

 combinations that will include two smooth- 

 stemmed factors and two white-fruit factors, and 

 thus giving us a certain number of seedlings of 

 this second generation that will have smooth stems 

 and will bear white berries — ^which chances, per- 

 haps, to be what the crude human experimenter 

 is seeking. 



The Architects on Strike 



But now let us attend to a case in which a more 

 complex hybridization was made; that, let us say, 

 in which the pollen of an apple was brought to 

 the pistil of a dewberry. 



Now we must call attention to a feature that 

 we have ignored heretofore — the segregation of 

 body plasm and germ plasm at an early stage of 

 the union. 



The coming together of the two germ plasms 

 gives a stimulus to growth. The berry develops, 

 and a drupe is formed that is like a dewberry be- 

 cause the body plasm of the dewberry is acting as 

 carrier. That is to say, the dewberry is the pistil- 

 late parent. 



The elfin architects in a single ovule get to- 

 gether. They separate out the body plasm, and,
