SUMMARY 461 



mation of the western crabs with the domestic apples, 

 for the plains and the northwest. Beyond these four 

 emphatic needs, I think that there are none which 

 stand out clearly and unmistakably above all others, 

 although there are a score of native fruit -types which 

 are crying for attention. Among them may be men- 

 tioned the chestnuts, pecans, gooseberries, currants, 

 cranberries, huckleberries, juneberries, cherries, mul- 

 berries, elderberries, and all the tribes of hickory nuts 

 and walnuts. 



The stimulus, or raison d'etre, of the improvement 

 of native fruits will be the increasing demands made 

 by a complex civilization ; and the actual work of 

 improvement will be done by a few patient souls 

 whose love of the work far outruns desire for 

 applause and for pecuniary reward.
