Notes, with EncraTinca, of "Crystal "Wax" Crosioa. 



The "Crystal Wax/' with its attractive, pale silvery-green^ 

 fleshy pods, produced in profusion, and, bearing small white seed^ 

 promises to be one of the best varieties for breeding purposes. Of 

 its seven combinations grown the past season, all except one gave 

 a gi-een pod in the blend ; this is sufficient reason to consider the 

 "Crystal Wax" a green-podded variety, at least as to its breeding 

 characters. Five of the above crosses in their second generation 

 show three types of pods, namely, green, '^Crystal" and wax. 



The blend of ''Crystal-Bismarck" (145/102) produced pods 

 strongly marked with purple, a character which was very promi- 

 nent in the plants of the first generation grown in the gi*eenhouse,. 

 and also seen in some plants of the second generation in tbe field. 



The "Crystal-Chocolate" (145/11) cross had the green pod in 

 the second generation, and selection for the "Crystal Wax" type is 

 being made. 



In the "Crystal-Burpee" (145/101) and "Crystal-Davis" 

 (145/112) crosses a fine white wax pod is produced that may 

 prove desirable to propagate. Plate XV. represents three plants 

 of the "Burpee" cross, taken July 9tli in the field row, when the 

 pods were at a marketable stage. The plant to the left has the 

 Avhite wax type of pod with the form of 101. The middle plant, 

 in foliage and color of pod, is quite close to the "Crystal Wax," 

 while the plant to the right is gi'een-podded and combines the 

 forms of both parents. 



"Crystal-Black Valentine" (145/45). The blend of this cross^. 

 grown in 1905, was a fine thrifty plant Avitli an abundance of long, 

 round wax pods. The seed was black instead of the usual mottled 

 type, resulting from the union of plants with black and white 

 seeds. A second crop of nine plants was grown the same season, 

 some producing wax pods similar to those of the blend, others 

 gi'een pods resembling those of the "Black Valentine," but neither 

 the "Crystal Wax" type of pod nor white seeds made their ap- 

 pearance. In the second generation, which was represented the 

 past season by three hundred and thirty-nine plants, the same char- 

 acters of the immediate parents prevailed without exception. 



Plate XVI. shows a wax-podded plant in the center, and one 

 with green pods upon the right, and another upon the left, as they 

 stood in the field Julv 0th.
