reprint of that survey in our 7th Annual Report. The percentages 

 of organic matter are given in most cases, and of calcium carbon- 

 ate in a few cases, and the columns should total 100% without 

 the calcium carbonate.* 



The samples are grouped by regions, in the same order as in the 

 other parts of this report. Descriptions of them follow, and the 

 analyses constitute Tables 9 to 14. 



Gulf Hammock Region 



1. Clayey low hammock ("Parkwood clay loam"), Sumter 

 Co. Average of two localities, viz., 2^/2 miles s. w. of Wildwood 

 and ^ mile s. e. of Coleman. Depth 0-5 inches. (Ocala area) 



2. Subsoil of same two localities, 5-20 and 5-18 inches. 



3. Lower subsoil of same, 20-36 and 18-36 inches. 



4. More sandy low hammock ("Parkwood fine sandy loam"), 

 Sumter Co. Average of two localities, viz., 2 miles n. w. of Cole- 

 man and 2 miles e. of Carlson's Ferry. Depths o-io and 0-12 

 inches. (Ocala area.) 



5. Subsoil of same 10-36 and 12-36 inches.

*One sample reported on in Bulletin 13, representing rich heavy hammock 

 near Altoona, has been excluded because it totals less than 95% and it has been 

 impossible to locate the error after the lapse of so many years.
