3. Honolulu, with its numerous scientific bureaus and edu- 

 cational institutions, can serve most favorably as a base. 



4. These same bureaus, schools, and other organizations 

 can make good use of the results of such a survey. A biolog- 

 ical survey of Oahu would be utilized ])y a large number of 

 individuals and institutions, both private and governmental. 

 Two quotations from publications of the College of Hawaii 

 will illustrate this point : 



"Not only is this remarkably varied region quite available 

 for college work and investigation, but it is also accessible 

 every day in the year, due to the charming climatic conditions 

 of Hawaii. The absence of a winter season, the entire absence 

 of snow and frost," the great rarity of storms, and the balmy 

 quality of the showers, make it possible to conduct field studies 

 on any day of the college year. There is no dormant or leaf- 

 less season ; plant life flourishes throughout the year, and field 

 observations and collecting suffer no abrupt changes because 

 of seasonal inclemencies. 



"The natural background of the college thus afford an un- 

 rivalled out-door laboratory. It is the policy and practice of 

 the botanical instruction of the college to utilize, so far as is 

 practicable, this natural background. Field work holds an 

 important ])lace in both elementary and advanced instruction. 

 The abundance of fresh material, easily obtainable, adds to 

 the effectiveness of all of the biological instruction." 



1. Field Biology. A course consisting of field work, de- 

 signed to give the students a vivid and first-hand knowledge 

 of the biological world. Within easy reach of the college is 

 an unusual variety of representati\'e biologic regions. The 

 ratural history of these type regions is studies in situ, and 

 recorded in written reports.
