118 MANUAI< OF NATURE STUDY. 



Store house from whicli the plant next year may- 

 draw supplies for the development of cabbage 

 seeds, which when sown will produce new cabbage 

 plants. The potato, in its native country, is used 

 in the same way, but man and animals have taken 

 advantage of these plants, broken open their 

 store houses, robbed them of their supplies, and 

 made merchandise of them. But man is not a rob- 

 ber after all, for he repays the plant for all that he 

 has taken. 



How does he do this? How do other animals 

 repay the plant? In dissemination, etc. See inter- 

 dependence of plants and animals, fourth grade 

 work. Fine fruits, as apples, cherries, strawberries, 

 peach, plum, are used by the plant for the same 

 purpose of reproduction. Their flesh is edible and 

 colorations attractive, both of which lead to dissem- 

 ination of seed for the plant as well as commerce 

 for man and food for animals. Draw the conclus- 

 ion that self-preservation is the first great law of 

 nature, and that in obedience to this law, the plant 

 produces seed and fruit in order that it may live 

 again; also, that when it yields up its fruit and 

 store of nourishment to man for his food, the pur- 

 pose of the plant is not defeated as it may at first 

 appear, but strengthened, in that man now becomes 

 the friend of the plant in its struggle for existence.
