Opportunities for Further Experiment 



After an interval of many years, during which 

 I did not experiment further with the bean, I 

 have somewhat recently found time to turn atten- 

 tion again to this very interesting plant, and have 

 developed a large number of new varieties of 

 unusual qualities. 



The recent experiments have had to do with 

 the bush bean, and I have paid attention to a 

 large number of attributes, including form of the 

 plant, color of bean, and the quality and flavor. 

 The new experiments have involved the crossing 

 of many varieties and have brought to light many 

 interesting developments, although none perhaps 

 more striking than those just outlined. 



It has been found that it is feasible to segre- 

 gate and recombine the traits of different varie- 

 ties of beans in almost any desired combination. 

 Thus, for example, it is perfectly feasible to put 

 the pod of one bean on the vine of another, quite 

 as Mendel did with his peas. Observation will 

 show what qualities or characteristics are pre- 

 potent or dominant even without directive effort 

 on the part of the plant experimenter. 



It will be observed that in the second, third, 

 and fourth generation plants will appear that 

 show the pods and beans of one of the original
