There are various other wild Solanums 

 growing, as did these original potatoes, in South 

 America, that might advantageously be tested as 

 to their hybridizing possibilities in connection with 

 the cultivated varieties. It need scarcely be added 

 that such experiments will ultimately be made in 

 which all allied species of potato will be tested; 

 and it is highly probable that this will lead to the 

 development of new varieties of tubers that will 

 surpass the potatoes of to-day as markedly as 

 these surpass the wild ancestors from which they 

 have been developed in comparatively recent 

 times.

I had been imbued from 

 the very outset with the idea 

 that inasmuch as existing 

 plants had all evolved from 

 inferior types, it should be 

 possible to develop any or 

 all of them still further.
