with its relative, the mulberry, did not prove 

 successful. 



But this was probably because I did not give 

 enough time and patient attention to the effort. 

 The two fruits are botanically related and I some- 

 times think of the fig as a mulberry turned outside 

 in. 



It should be possible to effect hybridization 

 between the two species, and perhaps greatly to 

 improve one or both of them; possibly even to 

 develop a wholly new fruit through this union 

 like the plumcot. 



MOVING TROPICAL FRUITS NORTHWARD 



We need not enter into further details in 

 connection with the subject of tropical fruits be- 

 cause I am chiefly concerned in this narrative to 

 tell what I have accomplished in the way of plant 

 development rather than to dwell on unrealized 

 possibilities. But I cannot refrain from urging 

 upon others who are geographically so located as 

 to bring the tender fruits within the range of their 

 experiments, the desirability of undertaking ex- 

 tensive series of investigations in this practically 

 untrodden field. 



It should be recalled that all of our fruits, even 

 the hardiest ones that now penetrate to the Arctic 

 Zone, must have come originally from the Tropics. 



The fact that the plum and pear and apple
