herbage and twenty-six purple herbage. All tho (^ plants were 

 very tall in 1891, mostly dark in foliage, and late. 



The result of all this experiment with secoiidaiy crosses and 

 the second generation of primary crosses, numbering 2,J*20 plants, 

 shows that they were exceedingly variable, that pollination from 

 the same plant did not fix the types, that very few novel and 

 promising types appeared, that the white and purple <olors tend 

 to unite to produce striped fniits, and that tli;^ greater part of 

 thfc crop was unsalable because of the nonde.'^cript colors of rhe 

 fruits. And all this only emphasizes the fict which we have 

 learned with many other plants, that crossing for the pui'j)ose of 

 producing marked novelties for propagation bj seed is at least 

 unsatisfactory. 



The following table showing the numerical measures of this 

 variation may interest those who are curious concerning plant 

 variability:
