DELIGHTFUL BERRIES 341 



work the crop could without doubt sooner or 

 later be more than doubled in quantity, the size 

 of the berries greatly increased, and their qual- 

 ity improved. 



The most desirable characters for the plant 

 developer to have in mind would be, first, qual- 

 ity of the fruit; next, size and color. The vines 

 themselves could be readily 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 some advantage. 



The cranberries differ less than plants that 

 have been more under cultivation, but they 

 nevertheless show enough of variation to give 

 full opportunity for selective breeding; and of 

 course the variation could be increased by cross- 

 ing as with other species. The common swamp 

 blueberry V '. corymbosum is one probably prom- 

 ising the most in the way of improvement for 

 general cultivation. 



Two INTERESTING TREE FRUITS 



To conclude this survey of common fruits that 

 beckon the plant developer, yet which have been 

 largely neglected, brief reference must be made 

 to the berries of two plants that differ radically 

 from those we have had under consideration,
