tained seeds that resembled the "Scarlet Eunner" in being marked 

 Avith red, but of much smaller size. It is not likely that this hybrid 

 will prove of value as an edible bean, but it adds another color to the 

 flowers of a thrifty, almost ever-blooming ornamental vine. 



The efforts to cross the lima with the bush beans have been con- 

 tinued without results. 



Notes upon Bean Crosses. 



During the year four crosses of bush beans have been carried forward 

 to their third generation, namely — first, "Bismarck" (102) upon "De- 

 troit Wax" (113); second, "Jones' Stringless" (131) upon "Golden 

 Eye" (130) ; third, "Davis' Kidney" (111) upon "Bismarck" (102) ; 

 fourth, "Early Mohawk" (31) upon "Silver Bush" (38), and many 

 crosses were carried through the second generation. 



The first of the five crosses is expressed in the record-book by the 



102 



fraction J13 — that is, the male ("Bismarck") is one of the black wax 



type, while the mother is of the golden wax group ; the former is black- 

 seeded and the latter is chiefly white, with a large, irregular brown 

 "eye." On account of the color of their seeds the black wax beans 

 are not as desirable as those with white seeds. While there may be no 

 distinct difference in texture or flavor, the dark seeds give a discolor- 

 ation to the pods, when cooked, that is not pleasing to the eye. 



As there is no noticeable immediate influence (xenia) observed in 

 these crosses, the first generation begins with seeds that are, so far as 

 appearances go, the same as those of the mother plant. For example, 

 the seed of the cross of "Bismarck" upon "Detroit Wax" is of medium 

 size and white, with a large, brown eye, like the mother, and shows 

 none of the black of the male parent. The plants of this first gener- 

 ation were medium tall, resembling the male parent ("Bismarck"), 

 maturing early its long, straight pods. The seeds were dark mottled 

 and of medium size, and were the beginning of the second generation 

 of the cross. These plants showed much variation in size, some being 

 quite tall and others short, while the flowers ranged from purple, like 

 the "Bismarck," to white, as found in the "Detroit," and the pods 

 varied from long in the male parent to short in the mother. At ma- 

 turity three types of seeds were found, namely, plain black, dark
