Fig. 3 gives the curve representing the variation in number 

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

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

 was 3.4(5, l)ut the typical pod contained 4 peas, — distinctly 

 more than the average. 



Fig. 3. 



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?
