But perhaps the most singular and interesting 

 anomaly was that some of these hybrids bore 

 flowers and fruit in every month of the year, 

 though sparingly. At the time when I had a large 

 colony of blackberry-dewberry hybrids, ripe ber- 

 ries could be picked from one bush or another 

 almost every day of the year. 



The possibility of producing, with the aid of 

 such hybrids, commercial varieties of blackber- 

 ries that will fruit at all seasons is inviting. Ex- 

 periments already far advanced have greatly ex- 

 tended the blackberry season, and there is reason 

 to expect that the blackberry lover in the future 

 will be able to secure this fruit, in one variety or 

 another, from early spring until almost the onset 

 of winter. 



As to other possibilities of blackberry devel- 

 opment, something was said in t]he earlier chap- 

 ter that described the development of the white 

 blackberry. But much remains to be told. The 

 chief development, however, through which not 

 merely new varieties but new species of berries 

 have sprung from the amalgamated stock of the 

 forty-odd species of bramble fruit with which I 

 have experimented, have had their origin in hy- 

 bridizations that linked the blackberry with its 

 relative the raspberry.
