LESSON 23 

 EARTH'S UNDERGROUND STOREHOUSE 



MEMORY VERSE 



Surely there is a mine for silver, 



And a place for gold which they refine. 



Iron is taken out of the earth, 



And copper is molten out of the stone. 



Job 28 : 1, 2 



The Purpose 



The intention of this lesson is to show not only the 

 beneficence of God in storing the underground world 

 with treasures as beautiful as they are useful, but also 

 the marvelous working of that law by which the world is 

 ever changing and always for the better. 



This idea will be repeated in many of the succeeding 

 lessons. 



Suggestions for the Teacher 



If a visit to the museum could be made between the 

 lesson on crystals and this one on metals, the children 

 would have a much clearer idea of the way the metals 

 are deposited in the veins of the rocks. 



Use familiar objects to make the point of contact for 

 the pupils. What metals do they see about them, in their 

 homes, in the town? Which is most useful? which most 

 beautiful? The course by this time should have helped 

 the pupils to want to know where these common objects 

 were formed ''in the beginning."
