work more thorough. Such ideal conditions do not always exist. 

 This is especially true where the period of bloom is a long one. It is 

 during conditions not so perfect, when the weather is damp and the 

 pollen is sticky and not so easily blown about, that the journeying 

 back and forth of the insects plays a conspicuous part in the produc- 

 tion of harvests of fruit or seeds. It is also apparent that when cer- 

 tain varieties are isolated from others of their kind or when the dis-. 

 tance between them is great, or they are in a direction from each 

 other that the wind can not carry the pollen, the chances of pollena- 

 tiom are cut off, with the result that there is no setting of fruit. 

 . There have been instances where insects were not present, that the 

 side of a tree from which the wind was blowing the pollen bore no 

 fruit, while the other side yielded abundantly, showing how the bees 

 might have aided. Careful investigation has demonstrated beyond a 



Showing the perfect and imperfect development of the carpels of fruits due 

 to proper and improper pollenatiou of the blossoms.
