 pared to hear the least sound that pervades our retreat. 

 Some of the sweetest notes ever uttered in the wood are 

 distinctly heard only at such times; for when we are 

 passing over the rustling leaves, the noise made by our 

 progress interferes with the perfect recognition of all 

 delicate sounds. It was when thus reclining, after half 

 a day's search for flowers, under the grateful shade of a 

 pine-tree, now watching the white clouds that sent a 

 brighter daybeam into those dark recesses as they passed
