COMPLETE KIT OF POLLEN 

 IZING TOOLS 



This shows all the apparatus required 

 for elaborate experiments in cross-fer- 

 tilization. The scalpel is used some- 

 times to cut across unopened blossoms 

 for example, apple blossoms in such 

 a way as to remove the pollen-bearing 

 anthers all at once. Where the form of 

 the flower does not permit this, the 

 pincers are used to pluck out the sta- 

 mens. The watch crystal is used on 

 which to collect pollen, which is trans- 

 ferred to the stigma of another flower, 

 either with the flnger tip or with a 

 camels-hair brush. The other imple- 

 ments are sometimes required to manip- 

 ulate a flower of peculiar form. The 

 magnifying glasses are needed only 

 with very small flowers. The use of the 

 paper bags is illustrated elsewhere. 

 The cardboard labels are to record the 

 experiment.
