252 STUDIES IX THE FIELD AND FOREST. 



clearly into the blue heavens, without any changes ex- 

 cept from darkness to light, through all the degrees of 

 twilight, the charms of the morning would be greatly 

 diminished. But nature, that all hearts might be 

 enamoured of the morn, has wreathed her temples with 

 dappled crimson, and animated her countenance with 

 those milder glories, that so well become the fair 

 daughter of the dawn and the gentle mother of dews. 

 In ancient fable Aurora is a beautiful nymph, who 

 blushes when she first enters into the presence of Day ; 

 and the clouds are the fabric with which she veils her 

 features at his approach. But a young person of sen-

 probably one cause of the tonic and healthful influence 

 of early rising. 



Many theories have at different times been advanced 

 to explain the cause of the varying tints of the clouds; 

 but it is at length conceded that they receive and reflect 

 the sun's rays as they are changed by passing through

 summit, deepening into crimson and purple in the 

 middle, and fading into dusky twilight at the base of 

 the mountain. Hence in winter, when the sky is per-
