SECOND ANNUAL REPORT. 
27 
notebooks have been available and were occasionally drawn upon by 
the writers. 
The investigations leading to the present report were enabled 
primarily through the passage of the act incorporating the new State 
Survey. At the same time the National Survey was engaged in a 
comprehensive investigation of the geology of the Atlantic and Gulf 
Coastal Plain of the United States, and hence cooperation between 
the two bureaus enabled a more thorough study than could have 
been carried out in a single season by either bureau alone. 
In October, 1907, Mr. Clapp began a field study of the stratigraphy 
and underground water resources of Florida. In November he was 
joined by Mr. Matson, and together they remained in the field con¬ 
tinuously until May 1, 1908, visiting nearly every town in the State 
and gathering as many data as time would permit. 
Having exhausted the funds available for field expenses, the writ¬ 
ers repaired to the office about May 1, 1908. On July 1, 1908, Mr. 
Clapp resigned from the U. S. Geological Survey, and the work of 
preparing the manuscript for the report was entrusted to the senior 
author. The base map which accompanies the report was prepared 
by the Topographic Branch of the U. S. Geological Survey. 
ACKNOWLEDGMENTS. 
The interest and cooperation of the people of Florida have rendered 
this work a pleasure, and the authors wish to make public acknowledg¬ 
ment of the numerous favors and courtesies extended to them while 
in the field and office. Several persons deserve particular mention,

J. C. Meredith, Constructing Engineer, Key West Extension, and 
other officials of the Florida East Coast Railway, for affording 
opportunity to visit the extension of the railroad during process of 
construction. 
Hon. Frank Clark, of Gainesville, furnished introductions which 
greatly facilitated the work. Dr. De Witt Webb, of St. Augustine, 
and Dr. E. S. Grill, of Palatka, have interested themselves in the 
work. Many well drillers have furnished logs and records which 
added valuable data to ' our knowledge of the underground stra¬ 
tigraphy, and it is a pleasure to mention particularly Capt. Alexander 
Near, of Eau Gallie; Mr. H. C. Haven, of DeUand; Mr. W. D. 
Holcomb and Mr. Edward Pettigrew, of Manatee; Mr. H. W. Pearce, 
of Arcadia; Mr. H. Walker, of St. Augustine, and Mr. Wm. E. 
Hughes, of Charleston, S. C. All these and many others, who can not 
be mentioned on account of lack of space, have given substantial assist¬ 
ance. Many citizens have interested themselves in acting as guides 
and in furnishing specimens and samples from wells. The officials of
