inated. The combination is one of the happiest, 

 as the acidity of one is modified by the sweetness 

 and aroma of the other. The berries were more 

 than three times as large as those of the Gregg, 

 and almost twice as large as those of Shaffer's 

 Colossal, which until the production of these new 

 hybrids bore the largest raspberries known. 



Another cross of the Gregg, this time with the 

 Souhegan, produced a seedling that had astonish- 

 ing crops of fine, medium-sized, red berries, that 

 ripened during October. The Souhegan was also 

 crossed with the Shaffer, and this union produced 

 in the second generation a new variety that was 

 known as the Sugar. 



From the seeds of other members of this same 

 generation two or three other promising berries 

 were produced. One of these bore large, firm ber- 

 ries, conical shaped, and a dark rich purple 

 color. 



A NEW SPECIES THE PRIMUS BERRY 



All the raspberries commonly known to the 

 cultivator, and many new ones that I imported 

 from Asia and the Southern hemisphere, were 

 growing on my grounds from 1890 to 1900, and 

 were intercrossed very extensively. Numbers of 

 highly interesting hybrids were thus produced, 

 and at least one of these was of so distinctive a 

 character as to merit the title of a new species.
