IN THE PRIMEVAL FOREST. 261

In descriptions of natural objects or scenery, both in

 picturesque relations to the varied surface of the earth 

 (as a small fragment of the whole terrestrial life) affords 

 materials towards the study of the Cosmos, and also tends 

 to advance it by the stimulus or impulse imparted to the 

 mind when artistic treatment is applied to phenomena 

 of nature on a great scale.
