B-9-6 and B-9-10, where the former are nearly round and the 

 latter flat as Limas and adhere closely to the "Scarlet Runner" 

 parent. In the lowest row, B-12, the color is the most unlike 

 visible character, for it ranges from a solid dark brown (nearly 

 black) and solid blue through mottled browns and greys to seeds 

 that pass for a dirty white with a brown "eye." 



It is seen from a study of the offspring from the ten sets of 

 plants that there is a showing of white in B-2, B-3, B-4, B-9 

 and B-12, or a full half, and a total of 18 plants with solid white 

 seeds and several that carried very little color of any sort. 



It is not the purpose here to account for this absence of color 

 in the seeds of hybrids, the parents of which were far from 

 white, but it may be said in passing that any color possibly may 

 hide the character that, otherwise, might produce a white seed. 

 Thus, in sweet corns, it is established that black or yellow grains 

 may carry "white" blood that, in the next generation, will show 

 itself when both parent germs are free from the color character. 

 The "Scarlet Runner" has a white-seeded strain, and the seed 

 used for the hybrids in question may have contained more or less 

 of this white character, obscured by the mottled purple of the 

 normal seeds. In like manner the light brown seeds of the 

 "Tennessee" may have carried the same "tendency" to produce 

 white; one or both of which suppositions would be enough to 

 account for the white-seeded plants met with. There may be 

 another principle in breeding that is at work here. 



"Scarlet Runner-China Red Eye" Hybrid (63/9). 



The hybrid above mentioned is now in the first generation 

 after the blend, and the seeds from the nineteen plants are repre- 

 sented by the formula B-i, B-2, etc. Ten of the plants were 

 early in fruiting, one medium early, two medium late, four late 

 and two unrecorded, fifteen being of the bush type and four run- 

 ning or wide-spreading. In color of blossom the range was 

 from white, (the largest number) through pale stripes, pink to 

 salmon and purple. The pods were quite variable, upon some 

 plants being short and flat, others long and curved, with or with-
