Farther Notes Upon Seeds of the Above-Named Bean Crosses. 



From among the above list of cM'osses of the bush beans four 

 groups are seleeteid for a combination group in Phite XIV. The 

 first pile of each row represents the male parent of the crosses in 

 its respective row, while the last pile is correspondingly the female. 

 Thus, in the first row, the beans at 1 are of the ''Earliest Green 

 Pod" (No. 14 of the recorded list), while the variety crossed upon 

 is represented at 7, namely, the "Bismarck Wax" (102). All of 

 the crosses shown bet^veen the piles 1 and 7 are represented by the 

 fraction 14/102, which, as before explained, indicates that the 

 green-podded sort was used as the male, while the wax variety bore 

 the seeds obtained by the artificial pollination. 



The '"Earliest Green Pod" is a variety with a large, medium 

 early plant, bearing pink flowers, followed by long, flat pods con- 

 taining medium-sized light brown seeds with cur\'ed bands and 

 blotches of pink. The "Bismarck" is an early, medium-sized va- 

 riety with purple flowers, long, flat wax pods that mature black, 

 plump seeds, below mediinn size. The ten seeds of each sort at 

 the ends of the upper row in the plate give relative sizes and some- 

 thing of the color characteristics of the two varieties. 



The seeds of the crosses are arranged somewhat according to the 

 apparent resemblance to the parents, and therefore at 2 the beans 

 approach the form and markings of the male parent (1), but they 

 are much ligliter and longer and more attractive to the eye. At 3 

 the seeds are without markings excepting a distinct brown eye, 

 while the body of the seed is colored an olive tan not altogether 

 ])leasing to the eye and not met with in any of the commercial sorts 

 in the collection. 



The seeds of 4 are coarsely mottled wdtli nearly a seal brown 

 upon a lighter backgroimd, giving a bean that photographs nearly 

 black, but is a mixture of two closely-related browns, and produc- 

 ing a strange-looking seed that in itself is unattractive. Quite in 

 conrrast with the last is the lot at 5, where the amount and dispo- 

 sition of the nuirkings are practically the same as in 4, l)ut the 

 contrasts are strong between the two colors, namely, a dark purple 

 u]M)n light gray, thus producing an attractive bean. The seeds at 

 C) are practically black, as much so as the "Bismarck," near which 

 they are placed in the plate. The two, howev^er, are quickly dis-
