seeds at 2 are somewhat larger tlian the "Jackson" and the color 

 is nearer a dull red than a dark purple as in the male parent, and 

 the seeds of the cross are more nearly alike in their marking than 

 in the "Jackson," in which there is a decided tendency to produce 

 dark seeds, some of which are shown at 1. The seeds at 3 are uni- 

 formly of a dark red and not at all striped or mottled and are 

 slightly larger than the "Jackson." At 4 the seeds are not far from 

 ^hose of 3 in color in the picture, but show some differences when 

 .-a close comparison is made of the two. The plant was less prolific 

 :and seems to be somewhat nearer the "Burpee," ten seeds of which 

 make the end pile at 5. The one white-seeded crossed plant did 

 not have seeds ready when the picture was made. 



In the next row are shown four crosses of the "Jackson" upon 

 the "Henderson." As the former is the male parent in all the 

 crosses sho'wn in tlie plate, seeds of it are omitted in all except the 

 first row. Here the seeds are generally not as large as when the 

 '■'Burpee" blood is present, but it is evident when this row is fur- 

 ther compared with the one above it that the "Burpee" has not 

 fulfilfe'd the expectations as to the hoped for increase, the size of the 

 crosses. In other words, the "Jackson," as regards size, has a 

 stronger influence upon the progeny than the "Burpee," and again 

 illustrates the familiar result in breeding that it is easier to hold 

 down than to lift up. Upon the other hand, as regards prolificness, 

 the "Burpee" seems to impress its lack of fruitfulness upon the 

 cross, which is only another instance of the greater do^vnward pull. 

 The two ]ilants, seeds of which are shown at 6 and 7, respectively, 

 were quite alike ; in fact, the plants of the whole plot were uniform, 

 as might be expected, for both parents are nearly the same in char- 

 aeteTistics outside of the color of the seed. At 8, the seeds are of a 

 handsome dark purple, uniform^ in all respects and quite different 

 in superior plumpness from the flat and somewhat larger seeds at 4. 

 In this set of crosses there were several white-seeded plants, and 

 the pile at 9 indicates that these "albinos" are decidedly prolific. 

 They are placed in comparison with the "Henderson," the selected 

 seeds of which are shown at 10. 



Tlie third row deals with the crosses of the "Jackson" and 

 "Wood's Prolific." The latter has a plant and seed somewhat 

 between the "Burpee" and "Henderson." The seeds shown at 15 

 indicate this fact, so far as the beans are concerned. The crosses
