Xm.] SEED -PRODUCTION VS. AMELIORATION. 255 



lation to the extent of departure. Let us compare the 

 Cherry and the Mikado. The fruit of the Mikado is 

 about fifty times heavier than that of the Cherry, yet 

 the seed -production is only three times as great. If 

 similar comparisons are made between the Cherry and 

 other varieties, we shall find other degrees of dissim- 

 ilarity between development in number of seeds and 

 size and weight of fruit. In other words, seed -pro- 

 duction in all fruits which fall under this third cap- 

 tion is an incidental variation, the same as form, 

 color, size, flavor, texture and other characters are.
