berry was crossed with a great variety of other 

 raspberries and blackberries. 



And among the hybrids thus produced there 

 was at least one that might be considered more 

 remarkable even than the Primus berry. 



This was the fruit which afterward became 

 famous as the Phenomenal berry. 



This extraordinary berry was the outcome of 

 a series of experiments in which the red and 

 yellow raspberries were variously combined with 

 the dewberry. 



In the first generation of these hybrids, nu- 

 merous red berries and black berries were pro- 

 duced, but no yellow ones. A large proportion 

 of the red varieties followed the raspberry in 

 general characteristics except in form, but some 

 of them acquired the high flavor of the dewberry 

 combined with the aroma of the raspberry. 



Most of the seedlings of this first generation 

 resembled the wild dewberry in habit of trailing 

 along the ground. Yet there were some that 

 favored the raspberry, standing upright. In 

 flavor many were a good combination of the two 

 parents, but the variation was not pronounced in 

 this respect. Some were highly flavored while 

 others were quite insipid, and between the two 

 were all gradations. Variations in size and 

 shape were equally marked.
