In speaking of the peculiar climatic conditions existent on 

 Kina Balou, where these noblest and rarest of all the species are 

 only to be seen, Mr. Burbidge alluded to the great mist zone. 

 " This enormous mountain range is about sixty miles from the

 moisture-laden air from the sea, and this current sets in every 

 day about four or five o'clock. The diagram here given will 

 illustrate what occurs better than words. 



" Every night in the year there is a deluge of rain in what I 

 have called the Nepenthes zone of this mountain, that is, from 

 5,000 to 10,000 feet in altitude, and even if not raining in the
