As there are many varieties both of pears and 

 quinces, each having individual characters and 

 diverse hereditary tendencies, an inviting field is 

 open to the careful and patient experimenter in 

 crossing these distinct yet related species. If the 

 right combination can be effected, the results un- 

 doubtedly will be profoundly interesting and val- 

 uable. Precisely what these results will be, no 

 one can predict. But that new fruits, making 

 most valuable additions to the dietary, may ulti- 

 mately be thus developed, there is no reason to 

 doubt. 



The pear and its cousin the apple 

 are two orchard trees which have 

 long been companions and friends 

 of man.
