HARPER: PINE-BARREN VEGETATION OF MISSISSIPPI 553 
The government soil surveys of Lincoln, Wayne and Forrest 
Counties and the McNeill, Biloxi and Scranton areas, published 
in recent years, are valuable in this connection, but not as much 
so as if their authors had been more familiar with previous litera- 
ture and the local geography, geology and flora, and if chemical 
analyses of soils had been included. 
Itinerary.—In December, 1905, I spent a day in the pine- 
barren region of Mississippi near Hattiesburg, and the next day 
observed the vegetation from the train between Lumberton and 
the Pearl River en route to New Orleans. A few days later, in 
January, 1906, I traveled the whole length of the Mississippi 
coast by rail, with a brief stop at Gulfport. On October 18, 1908, 
traveling northward on the Mobile & Ohio R. R., I entered the 
state at State Line, in the northeastern corner of Greene County, 
and left the pine-barrens near Waynesboro, about 20 miles farther 
on. On July 20, 1911, I walked into Mississippi a few miles 
northeast of Buckatunna,* in Wayne County, and traveled.on the 
Mobile & Ohio R.R. from Buckatunna to State Line and beyond. 
In July, 1913, I entered the region under consideration from 
the west somewhere near Brookhaven, on the Mississippi Central 
R.R., and traveled through it for about 300 miles, via Wanilla, 
Foxworth, Columbia, Maxie, Gulfport, Pascagoula (formerly 
Scranton), Evanston, Beaumont, and Laurel.f On this trip notes 
were taken from the train nearly every mile, and also on the 
ground for a few minutes or hours in the vicinity of Columbia, 
Biloxi,t F ontainebleau, Pascagoula, and Moss Point. 
PHyYsICAL FEATURES 
Sotls.—The soil of the pine-barren region is in the main a 
sandy loam, the proportion of clay increasing with the depth. 
On the uplands the soil is usually grayish and the subsoil brick- 
red, and in some places the red clay comes nearly or quite to the 
Surface. There is at present some difference of opinion among 
geologists as to whether the surface sand and clay of this and
