256 OUR USE OF THE LAND 



struggle for the unrestricted use of minerals which are essential 

 to industry. It remains to be seen which of these two ideas 

 will gain and keep the upper hand. 



PROJECTS 



1 . If you live in a city, try to find the major minerals that the 

 factories in your city depend upon. Try to trace these minerals 

 back to their origin. 



2. We have made a statement that minerals are the essential 

 resource of industry. See how much evidence you can collect 

 to prove that this statement is true or untrue. 



3. Suppose you own an ore pit in Minnesota. About half 

 the reserves in this pit are high grade ore and the remainder is 

 low grade ore. How should you arrange to extract this ore? 

 Give your reasons for this plan. 



4. Find the value of the agricultural products produced in 

 the United States for the last year and compare this with the 

 value of the industrial products produced for the same period. 

 Now get a list of the value of exports and imports of agricul' 

 tural and industrial products. What do these figures indicate 

 to you and why? 



5. Make a list of mineral resources in the order of their im' 

 portance and explain how you think they are important. 



DEBATES 



1. Should the federal government control mineral production 

 as much as it controls agricultural production? 



2. Is the power of taxation a good method for controlling the 

 production of minerals? 



3 . Are minerals or crops more important from a national point 

 of view?
