FOEEST TEEES AND FOEEST SCENEEY 



the last rays of the sun, obscures the 

 contours of the forests and makes 

 them even more sublime. This, too,

The interchange between lights and 

 shadows cast by the moving clouds is 

 nowhere so effectively exhibited as in 

 higher altitudes and over the surfaces of 

 evergreen forests. A wide expanse en- 

 ables us to follow with our eyes the in- 

 teresting chase of the cloud shadows, as 

 they fly up the slopes, the steeper the 

 faster, and glide noiselessly but swiftly 

 over outstretched areas of endless green. 

 The clouds seem to move faster over 

 mountain ranges, as a rule, than they 

 do over the low valleys. Or is it only 

 because now we see them nearer by and 

 can gage the rapidity of their flight?
