A PRELIMINARY REPORT ON CLAYS OE FLORIDA 
261 
INDEX 
This index does not include the names of persons and corporations mentioned 
in the financial statement on pages 9-13, the mineral producers on pages 15-23, the 
fossils in Mr. Mansfield’s paper, or the counties in which no cla,y deposits of im¬ 
portance were found. All the fossils are listed by families and horizons in the folded 
table inserted between pages 28 and 29, and the counties are discussed in alphabetical 
order on pages 120-215. (See table of contents.) Names of places near which fossils 
or clay deposits were found are not indexed as a rule, for such references tell noth¬ 
ing about the places themselves. But such localities are indexed under the respective 
counties. Numbers in parentheses indicate indirect references.
