mottled and white witli a dark eye. In other words, there are the two 

 parent forms and an intermediate. 



From the mottled seeds a row of sixteen plants was grown during 

 the latter half of the present season, with the following results as to 

 character of seeds, representing the third generation: 



Plant a. Seeds largely black, but somewhat mottled. 



Plant b. Seeds dark, but more mottled than the last. 



Plant c. The same as the last. 



Plant d. Seeds white, with the "eye" larger and darker than "Detroit." 



Plant e. Seeds dark indigo and mottled. 



Plant f. Seeds white with the indigo "eye" very large, covering a third 



of the seed. 



Plant g. Seeds pure black ("Bismarck"). 



Plant h. Seeds white, same as f. 



Plant i. Seeds white, with small dark "eye" ("Detroit"). 



Plant ;'. Seeds dark indigo and mottled. 



Plant k. Seeds almost entirely black, obscurely mottled. 



Plant I. Seeds same as last. 



Plant m. Seeds same as last two. 



Plant n. Seeds white, like i. 



Plant 0. Seeds same as m. 



Plant p. Seeds a pure black. 



A dozen seeds from each of the above plants, with the parents, are 

 shown in Plate YIII. 



This row of sixteen plants gives a record, as shown above, of two 

 pure black, like the male parent ("Bismarck") and two of the 'T)e- 

 troit"' type, ^itli nine that are black (or indigo) mottled and three 

 which vary from the mother type somewhat. Thus, a, h, c, h, I, in 

 and would not be distingui.shed from each other Avhen mixed to- 

 gether, while e and ;' have the black replaced by an indigo. There is 

 a suggestion in this small number of instances thai possibly one- 

 quarter of the plants in this cross will reproduce each plant and one- 

 half the mottled or mixed form. In another row of the same cross 

 the eleven plants gave one black, four dark-eyed and six mottled. 



The next cross is recorded as |;^,,, namely, ''Jones' Stringless" upon 

 "Golden Eye." The male parent is of medium height and productive 

 of straight, rounded, medium length wax pods, maturing early its 

 plain white seeds. The motlier has a larger, broader plant than "131." 

 and bears flat seeds, distinguished by a yellow "eye." The first gener- 

 ation consisted of plants like 131 and the seeds were all mottled, of a
