The Five Oceans. 



18. Suppose that the salt should rise from the ocean with 

 the vapor ; what would the rain be, fresh or salt ? If rain 

 were salt, what effect would it have on our grass, trees, 

 grain, and flowers ? 



19. The changing of water into vapor is called 

 evaporation. The changing of vapor into water 

 is called condensation. Look at the chart again, 

 and see the vapor rising from the salt water of 

 the ocean and falling on the land far away as 

 pure, fresh water.

20. The words ocean and sea are often used 

 to refer to the whole body of salt water on the 

 earth ; which may be considered as divided into 

 five parts, also called oceans. There are five 

 oceans. I shall point on the map of the world, 

 and all (or each in turn) will repeat each name 

 after me Pacific Ocean, Atlantic Ocean,
