HARPER: THE ‘‘ PocosIN”’ oF PIKE County, ALA. 211 
Guided by the map just mentioned, the writer visited the spot 
on November 6, 1912, and March 27, 1913, and madea rough quan- 
titative study of its vegetation. An incessant rain at the time of 
the first visit interfered somewhat with note-taking and made 
photography out of the question, but conditions were more satis- 
factory the second time, when the views here published were 
taken. A brief mention of it, with the only photograph of its 
vegetation hitherto published, appeared last summer in my report 
on the forests of Alabama.* 
The so-called pocosin (Dr. Mohr’s description above quoted 
implies the existence of several such areas, but I know of only one) 
embraces a hundred acres or more, mostly in Section 7, T. 9 N., 
R. 22 E., in the midst of a few square miles of undulating sandy 
country on the east side of Walnut Creek, about half way between 
Troy and Brundidge, and about 50 miles south of the fall-line 
and 100 miles from the Gulf coast. The pocosin itself is practically 
untouched by civilization, except for having one or two little-used 
roads through it, but the surrounding sandy country is partly 
under cultivation. As observed by Thornton, however, the sand 
is much less productive than the loamy soils which prevail else- 
where in Pike County and other parts of the southern red hills or 
Eocene region of the coastal plain. Where not cultivated it 
bears a vegetation much like that of the sand-hills of Georgia,f 
but the soil is evidently a little richer in mineral plant food than 
that of the average sand-hill, as shown by the prevalence of Pinus 
echinata and the scarcity of Pinus palustris.t 
In the following list of sand-hill plants growing around the 
Pocosin the trees, shrubs and herbs are arranged as nearly as 
Possible in order of abundance, but the data are not sufficient for 
assigning percentages to them. Evergreens are indicated by 
heavy type.
