Senate Doc. No. 84. 



Plate XXXVll. 



ORIGINAL FOREST, NORTHWEST SLOPE OF THE GREAT SMOKY MOUNTAINS. (See pp. 23, 4.5, 53. ) 



There are no lakes or glacial gravels in this Southern Appalachian region, .such as abound in the Northern 

 States. Here the forest and the soil alone must catch the heavy rains and regulate the flow of the streams. 

 If the forests are destroyed the soils will be rapidly washed down into the river channels; and the terrible 

 floods will destroy everything along the great river valleys. (See also pp. 56, 133.)
