Fig. 3 gives the curve representing the variation in number 

 of peas, to the pod. Two pods in each 100 at the average had 

 no peas, while one in 100 had 8 and one had 9. The average 

 was 3.46, but the typical pod contained 4 peas, — distinctly 

 more than the average. 



Turning once more to the requirements of the practical plant 

 breeder, we, see that he would wish to grow the largest num- 

 ber of peas to the pod, as well as the largest number of pods 

 to the vine ; and the question arises immediately, whether 

 these two qualities are compatible. Do the vines bearing the 

 largest number of pods bear also the largest number of peas to 

 the pod? or are the pods with the largest number of peas borne 

 on the vines having relatively few pods?
