Other fruits noted were oranges, mangoes, papayas, guavas and 

 others less frequent. 



Trips were made to Hawaii and Kauai, respectively the most 

 southerly and most northerly islands of the group. 



Attention was drawn to the great difference in the amount of rain- 

 fall upon different parts of the islands, especially upon the two sides 

 of Hawaii. At Hilo the annual rainfall is 180 inches, and the vegeta- 

 tion in consequence extraordinarily luxuriant. Here the ferns reach 

 wonderful development and the tree-ferns reach their full size and 

 beauty. The ferns belong to much more diverse groups than in the 

 United States, and all of the principal groups are represented. 



On Hawaii the largest forests trees were met, but the variety is 

 much less than on Kauai, which is much richer, especially in flower- 

 ing plants. 



The different geological age of the islands was referred to, Kauai 

 being the oldest and Hawaii the youngest. Hawaii is, indeed, still 

 in process of formation. 



The islands being so isolated, and never having been connected 

 with any other land have developed a most peculiar flora. Of the 

 flowering plants and pteridophytes together almost 75 per cent, are 

 strictly peculiar to the islands, while of dicotyledons the percentage 

 is about 85, the highest known in any area of equal size.
