Tomato-Potato Grajt 



The grafting of potato tops on tomato roots and of tomato 

 tops on potato roots have constituted some of the most interesting 

 of Mr. Burbank's grafting experiments. The manner of grafting is not 

 altogether unlike that employed in the case of trees, but the experi- 

 ment has peculiar interest because Mr. Burbank has been 

 able to unite the stems of these plants, but has not 

 been able to cross-polfenate them successfully.
