 ma closed tight until all its pollen is shed ; others 

 place the anther so far away from the stigma as 

 to make pollen contact impossible; others actu- 

 ally imprison these pollen -bringing insects until 

 they can send them away with fresh pollen all 

 over their bodies. 



Take almost any flower we chance to meet, and 

 it will show us a mystery of form which the insect 

 alone can explain. 



Here is one, growing just outside my door — a
