 posal a large number of photographs made by him 

 in the almost untrodden wilds. Mr. Charles Deer- 

 ing has shown me unnumbered favors in making 

 me a member of collecting expeditions on his boat 

 the Barbee. Mr. Wilson Popenoe of the U. S. De- 

 partment of Agriculture, Professor Frances G. Smith 

 of Smith College, and Dr. Roland Harper have fur- 

 nished a ntimber of photographs and rendered val- 

 uable assistance. Dr. E. H. Sellards, former State 

 Geologist of Florida, contributed the map showing 

 the Pleistocene subsidence and has made valuable 

 suggestions. Mr. E. Ben Carter, Chief Engineer 

 of the Florida East Coast Railway, has kindly 

 allowed me to use the excellent map of a part of 

 Monroe and Dade counties which was made from 

 surveys for the extension of that road. 



The map accompanying the text of this volume 

 was drawn by the author in pencil and inked and 

 lettered by Mr. Forrest Clark. The fine work of 

 the map of the East Coast Railway has been 

 freely copied with the permission of Mr. Carter.
