In many parts of my Journal, I have expressed an opinion 

 that travellers have exaggerated the beauty and brilliancy of 

 tropical vegetation, and on a calm review of all I have seen in 

 the districts I have visited, I must repeat it. 



There is a grandeur and solemnity in the tropical forest,
