ECONOMIC BOTANY OF ALABAMA. 



about half way between Troy and Brundidge, is a beau- 

 tiful bit of virgin forest covering several hundred acres 

 and closely resembling the sandy hammocksj which are 

 common farther south. The trees in it are mostly of 

 species which cannot stand fire, and they are protected 

 from fire by being nearly surrounded by an area of dry 

 sand on which the vegetation is too sparse to feed flames. 

 The swamps vary from alluvial to non-alluvial, and each 

 kind has its characteristic timber. 



Fires are frequent on the wooded uplands, especially 

 where long-leaf pine is the prevailing tree, but rare in 

 the valleys, and almost impossible in ravines and 

 swamps.
