My itinerary through these two states was as follows : On 

 the ioth I spent most of the day in the vicinity of Norfolk and 

 Portsmouth, in a region which has often been visited by well- 

 known botanists, and has had its phytogeographical features de- 

 scribed in several published papers, particularly in Mr. Kearney's 

 admirable " Report on a Botanical Survey of the Dismal Swamp 

 Region." * 



On the i ith I went from Portsmouth westward sixty miles 

 through the coastal plain of Virginia and southwestward across 

 North Carolina, by the Seaboard Air Line, entering the latter 

 state near Margarettsville. About twenty miles farther west, 

 near Weldon, on the Roanoke River, the railroad crosses the 

 fall-line and enters the Piedmont region. Thence continuing 

 southwestward by way of Raleigh, the coastal plain is entered 

 again' near Sanford, in Moore County. 



From there to Hamlet, in Richmond County, near the South 

 Carolina line, where darkness overtook me, I passed through an 

 extensive sand-hill region which is doubtless a continuation of 

 the fall-line sand-hills of Georgia and South Carolina. These 

 North Carolina sand-hills were particularly interesting to me be- 

 cause I had never seen them mentioned in botanical or geological 

 literature, and they probably have not been explored as much 

 as they deserve, though they are on one of the principal routes 

 of travel between the North and South, and are visited by many 

 tourists during the winter season. 



The inland edge of the Columbia formation (of which these 

 and other sand-hills in the southeastern United States are com- 

 posed) is represented on the best map of this formation I have 

 seen as being about forty miles nearer the coast, a remarkable 

 discrepancy. 



For the last fifteen miles north of Hamlet scarcely any signs 

 of civilization were seen. This is a characteristic feature of many 

 sand-hill regions, where the sand is so deep that the land is of 

 little value for agricultural purposes. 



Among the plants observed on this trip the following deserve 

 special mention.
