GOOD FORESTRY 579 



Practical Exercise 1. List all the various forest products found in your 

 community and give the uses of each. 



If there is in your community an industry which uses forest products, 

 visit it and give a report of your visit to the class. 



Other values of the forest. We have learned that forests 

 regulate the water supply. Much organic soil is formed from de- 

 cayed trees and other vegetation. The forest gives a refuge for 

 wild animals, particularly game such as deer, elk, and antelope. 

 There are now nearly 12,000,000 acres set aside as refuges for wild 

 birds and game, that they may not become extinct as have some 

 native wild animals. The clear streams of the forest are the 

 homes of many of our best game fishes. And perhaps, best of all, 

 the forest has become the playground for lovers of the out-of-doors 

 in our nation. 



Self-Testing Exercise 



Trees protect the soil by preventing (1). Land covered 



with trees can (2) (3) water better than land barren 



of trees. Paper pulp is obtained largely from (4) wood. 



Evaporation of water through the stomata of the leaves makes the 



surrounding air (5). Wood pulp is used for making 



(6) and (7) (8) (9) (10) are 



used for the " trim " of our houses. 



PROBLEM II. WHY IS THE CONSERVATION OF FORESTS 

 NECESSARY? 



Field Exercise. To study the forest resources of my community. 

 Divide the area to be covered into districts and let each member of the 

 class work over a small area. Count the number and kind of market- 

 able trees, estimate their size or approximate age, etc. Make maps 

 showing these areas, to scale, so that the maps made by the entire 

 class may be put together and an estimate of the entire region may 

 be formed. Since this is an economic project, it will be necessary to 

 get the help of practical lumbermen or field workers. 



What are the forest resources of your community? What special tree 

 products give factories employment in your home city. 



Good Forestry. The total forest area of the United States 

 today is less than 470,000,000 acres. More than 80,000,000 

 acres have been burned or cut, so that today they are waste land. 

 We have more waste forest land than the combined forest areas of
