The diagram as a whole shows the variation 

 at different parts of the ear, the butt being to 

 the left and the tip to the right. 



Thus far we have given the results of ex- 

 periments in all of which the seed was pro-

Fig. 10. — Illustratiug the product from larere and small seeds 

 of com. Data for the curves were obtained by weighing the 

 kernels on each ear of the product by fifties from base to tip. 

 The heaviest lot of fifty came not far from the base. These 

 maxima were averaged and marked "M," and the next fifties 

 right and left in succession were averaged in the same way. 

 Figures along the bottom of the diagram show position of 

 each fifty seeds, and along the side the average weight in 

 grams. The position of the ear of corn above corresponds to 

 the curves.

 give larger returns than the small seeds. It 

 would be natural to suppose that if the small
