The work of each week consists of one lecture, one laboratory 

 or field period, one reading assignment — all with accompanying 

 note-book records. 



The field work is an essential and distinctive feature of the 

 course. The College of Hawaii is remarkably situated with 

 reference to dendrological field studies. The island of Oahu, 

 upon which is the city of Honolulu, is a volcanic doublet, 25 

 by 35 miles, skirted in part by a wide coral plain and reef. The 

 Waianae Range, which forms the western portion of the doublet, 

 is of much greater age than the recent windward Koolau Range. 

 The Waianaes include a striking series of biological zones, from 

 extensive arid plains and valleys, up to a boggy summit of 

 4,000 feet elevation. The Koolau Range is deeply carved into a 

 picturesque succession of beautiful valleys, gorges, knife-edged 

 ridges, and peaks, all covered with dense rain-forest. These 

 two ranges compose the main mass of the island — originally 

 two islands — and between them lies an elevated central plateau, 

 deeply dissected by tortuous gorges. The coastal plains are diver- 

 sified as to geologic formations and plant societies, and certain
