ferent varieties were hybridized. By such work 

 the crop could without doubt sooner or later be 

 doubled in quantity, the size of the berries in- 

 creased, and their quality greatly improved. 



The most desirable characters for the plant 

 developer to have in mind would be, first, quality 

 of the fruit, next size and color. The vines them- 

 selves could be improved, both as to manner of 

 growth and abundant production. 



Here as with other berries it would perhaps 

 be possible to eliminate the seed, and this would 

 obviously be of great advantage. 



The cranberries differ less than plants that 

 have been more under cultivation, but they nev- 

 ertheless show enough of variation to give full 

 opportunity for selective breeding; and of course 

 the variation could be increased by hybridizing, 

 as with other species. 



Two INTERESTING TREE FRUITS 



To conclude this survey of common fruits that 

 beckon the plant developer yet which have been 

 largely neglected, I must make brief reference to 

 the berries of two plants that differ radically from 

 the vines we have had under consideration inas- 

 much as they are trees or large shrubs rather than 

 bushes. 



The plants referred to are the Mulberry and 

 the Elderberry.
