 nuts how could we expect an inkling, even, of 

 what the tomato with less than half a century of 

 cultivation could become?

 ment, we must look for help not so much to the 

 stamen counters as to the plants themselves as new 

 environment brings their old heredities into view.

Mr. Burbank has made combinations between 

 species; he has made combinations between 

 genera, not once, but many times; fertile, seed- 

 bearing combinations. 



How far, then, can plant combination be 

 carried? Is it possible to go above the genus and 

 make combinations between families? Or to go 

 above the family and make combinations between 

 the orders? Or to go above the orders and make
