RASPBERRY BUSH AFTER 

 POLLINATION 



Here small paper bags have been 

 tied loosely over the flowers that have 

 been cross-fertilized. It is not usually 

 necessary to resort to this expedient, 

 for if the stigma of a flower is entirely 

 covered with pollen, there is little 

 danger of subsequent contamination 

 with other pollen, especially if the 

 stamens also have been removed. To 

 make assurance doubly sure, however, 

 the paper bags may be used, particu- 

 larly by the amateur who operates on 

 a small scale.
