CATARACTS OF ATTIRES. 243 



seemed illuminated by the great nebulae of the south- 

 ern hemisphere. Multitudes of insects diffused a 

 reddish light over the air. The ground, profusely

 by the piling up of granite blocks, and enjoyed the 

 extraordinary spectacle of the river dashing in a 

 sheet of foam over their heads. The boat was to 

 coast the eastern bank of a narrow island, and take
