136 NATURE STUDY -BY GRADES 



squashes, melons, gourds, etc.? Why? What is the com- 

 monest color among the small fruits, as currants, cherries, 

 berries, etc. ? Account for this. What color is seen farthest 

 in the sunshine? Would green currants be seen as readily 

 as red, by a bird flying over the bush? 



Let the pupils look out of the window at recess and notice 

 among the children on the playground how a red dress or 

 ribbon attracts the eye as compared with other colors. How,

When do the bright colors appear on fruits? What is

 condition in unripe fruit? What is the taste of unripe 

 fruit? Would the seed grow then, if planted? 



Develop the fact that the color and flavor of the fruit 

 reaches the greatest perfection just as the seed becomes 

 fully developed and is ready to be scattered. Hence, these 

 qualities are evidently inducements to get animals to do 

 the work, while in previous stages both color and taste are

LESSON X 

 FRUITS ODOR AND SENSE TRAINING 



Let the pupils close their eyes and try to detect different 

 fruits by their odor. This will prove an interesting and 

 profitable game, or exercise. A certain pomologist in the 

 employ of the Agricultural Department is said to be able 

 to tell the variety of any apple by its odor. 



When is the odor of fruits strongest and most agreeable? 

 What can you say of the odor of fruits when green ? Like
