LESSON 20 



THE WORK OF THE RAIN: BROOKS AND 

 RIVERS 



MEMORY VERSE 



Thou shalt keep the commandments of the Lord thy God, to 

 walk in his ways, and to fear him. For the Lord thy God bringeth 

 thee into a good land, a land of brooks of water, of fountains and 

 springs, flowing forth in valleys and hills. 



Deut. 8: 6, 7. 



The Purpose 



This lesson deals with the tearing-down and building-up 

 force of rain water as it flows off the earth in brooks and 

 rivers. The general action is the same as that described 

 in the previous lesson, except that in this case it is the 

 larger forces in the brooks and rivers that are at work. 



The commandments of the Lord for our lives are as 

 definite and sure as those which direct the forces of the 

 rain. Our task is to find out the law of God as it relates 

 to our owm lives, that we may do it. 



Suggestions for the Teacher 



A map of a water system like that of the Mississippi 

 or the St. Lawrence will help the pupils to understand 

 the way brooks and small streams join to make a great 

 river. It should be used after, not before, the illustra- 

 tion of the fingers and the arm. 



The teacher should have as specimens to show to the 

 children an angular fragment of rock and a waterworn
