occupying the middle row of watcli glasses from left to right. The 

 parents of each are placed with the male above and the female 

 beloAv the cross. For exam])le, the first cross (sIioaati at 1) is that 

 of "First of All" (14) ui»n the "Black-Eved Marrowfat" (5). 

 The seeds of the parents are alike in being buff (light tan) colored, 

 but with the latter much larger, less wrinkled, and having a ehar- 

 acteristio dark eye, giving the name to the variety. In the cross 

 sho^\Ti above the latter the seeds are nearly midway in size between 

 tlie two parents, but they all have tlie eye-marking of the mother 

 parent. 



In the next cross the male jDarent, "Thomas Laxton" (31) has a 

 quite large and very much wrinkled seed, frequently retaining a 

 greenish color, while the mother is the "First of All" (14), as 

 named in the last cross, and has a medium-sized, often nearly 

 smooth, seed. The seeds of the cross are midway in size of the 

 two parents, and show (2) some seeds fully wrinkled, like the 

 "Laxton," while others are smooth, as in the "First of All," 



The "Admiral" (40) upon the "French Canner" (41) com- 

 bines two varieties representing two widely different types. In 

 the former the seeds are large and extremely wrinkled and of a 

 dull greeaaish buff color. The "French Canner" has small, spheri- 

 cal, typioally smooth seeds that are nearly flesh colored. The dif- 

 ferences in the plants of these two sorts are as great as here shown 

 at 3 between the seeds. The cross is near the mother in size of 

 seeds, three-quarters of which are smooth, somewhat larger than 

 the "Canner," but greenish like the "Admiral." It is interesting 

 to note that the wrinkled are larger than the smooth ones. A pod 

 is shown with the five seeds in plate, the second one from the base 

 being larger than the other and dimpled. 



At 4 is shown the seeds from a plant that grew from a pea ob- 

 tained by breeding the "French Canner" (41) upon the "Ameri- 

 can Wonder" (4). Here, again, the two parents represent the two 

 classes shown in the last cross but with the "Canner" in this case 

 as the mother. The results are nearly the same, for the small, 

 spherical, smooth pea seems to reduce the size to nearly that of its 

 own, the wrinkled ones being somewhat larger as sho-\vn in the 

 sample and also by the dimpled seed in the opened pod. The 

 seeds from one of the first generation plants were classified as fol- 

 lows :
