boards advertising where honey is to be found. While 

 this is true to a great extent, yet insects visit flowers 

 such as those of grape, mignonette, and English ivy, 

 which have no bright colors. In these cases the scent 

 of the honey brings them. We know that they can 

 smell honey long distances, while they can see but a 

 few feet. 



FIG. 50. How an apple grows from the flower. 



As they go from flower to flower, a good deal of pollen 

 sticks to them, and in this way it is carried. Most 

 flowers have some way of making sure that the insect 

 places the pollen on the right spot, that is, on the stigma. 



Wind brings pollen to some flowers. Plants which 

 depend on the wind to bring pollen do not have bright 

 flowers (grasses, oaks, hazels, poplars). The corn has 

 all its pollen in the tassel, from which it is carried by 

 the wind to the silk or long stigmas of the ear. The 

 hop and hemp have seed-bearing flowers on one plant, 

 and pollen on a different plant. The pollen-bearing 

 must be planted about among the seed-bearing plants 

 to supply pollen.
