taining the dried flowers and pollen and twirled around 

 so as to fill it with the pollen grains. This method is 

 rather wasteful of pollen and the one given above is pref 

 erable where only a small amount of pollen can be secured, 

 but for working on a large scale we have found nothing 

 better to substitute for it. After filling the brush with 

 pollen it is gently applied to the stigma. See that 

 plenty of pollen adheres to its surface. Then carefully 

 cover the pollinated flower or flowers, if a number 

 are together, 

 with a paper 

 bag, tie it tight- 

 ly around the 

 branch and be- 

 low the sack, 

 place a label in- 

 dicating the pol- 

 len used and 

 the date (fig.

Nothing more 

 needs to be done 

 until the fruit 

 has set. This 

 is indicated by 

 the dropping of 

 the style from 

 the ovary. If 

 at this time the 

 ovary is deep 

 green in color we may feel reasonably certain that the fruit 

 will stay and that seeds have commenced to grow. At this 

 time, about ten days or two weeks after pollinating, the 

 paper bags should be removed and replaced by sncks about
