BULLETIN 863, XT. S. DEPARTMENT OF AGRICULTURE 



While the class is on the open hillside, places will be found where 

 the soil, which has no roots to bind it, has been washed away by the 

 rain, and on some steep slope there will be deep gullies dug into the 

 ground. 



Where does the soil go that is washed down the slope? Into the

 bear to the well-being oi the land. The little examples that he finds 

 in his own neighborhood of soil protection and good streams, of

erosion and flood damage, are intimations of the larger meaning of 

 the Nation's forests to farm land and industry and commerce. His 

 own home woodland is a part of nature's plan to aid man and his 

 enterprise. 



Lesson IV. PRODUCTS FROM THE HOME FOREST

Sources of information. — Farmers' Bulletins 516, 1071, 1117, and 

 1210 ; Department Bulletins 12, 605, and 753 ; Yearbook Separate 779. 



Illustrative material. — Prepare a wall chart showing in a tabulated 

 form the varous wood products. In each product column write the 

 name of the tree or, better still, place a sample of the wood that 

 furnished that product. Prepare another chart showing in like 

 manner other timber products such as nuts, roots, bark, gum, and
