THIRD GRADE FALL WORK 137 



color and taste, the odor reaches its best when the fruit is 

 ripe. Of what use to the plant is the odor of its fruit ? Do 

 animals have a sense of smell? 



Recall the fact that the dog can follow his master by smell- 

 ing his tracks. Explain the use of bloodhounds in tracing 

 animals and criminals. Buzzards are said to be able to 

 scent a carcass one hundred miles away. It is not unlikely, 

 then, that the odor, as well as other properties of fruits, is 

 designed to attract animals in order that the seeds may be 

 scattered. 



A good exercise to cultivate the sense of taste is to cut 

 into cubes, or similar shapes, the pulp of several kinds of 

 apples, pears, or other fruits, and let the pupils determine 

 the kind from the taste. 



LESSON XI 



FRUITS CLASSIFICATION 







Cut open samples of the fruit to examine how they are 

 made, and the use of each part. 



What do we find on the outside of the apple? What is 

 the use of the thin, smooth skin? What will happen to the 

 apple if this be broken or a portion removed? Why do 

 worms most often enter the apple at the blossom end, or 

 where one apple touches another? 



Compare the skin, or rind, of various fruits, to bring out 

 the general and particular uses and adaptations of this 

 covering. 



What lies next within the skin? Of what use is the flesh, 

 or pulp, of fruits? This is usually the edible portion, and 

 its use has already been described. Compare the pulps 

 of different fruits.
