 promised exceptionally favorable conditions for infection, and it proved to be 

 so in each case. The plan of the experiment may be outlined as follows:

The spotted seed was largely of the wax type, and the pods were picked 

 when a majority were of marketable size as string beans. The results 

 from this experiment are given in table 7. The healthy pods, after being 

 sorted out, were left in a basket for three days. They were then sorted 

 again and the percentage of pods that had spotted in the meantime was
