Pinus echinata must have once occurred in this region, ac- 
cording to Pinchot & Ashe,* but I did not see any of it. Oxyden- 
dron, Quercus alba, Fagus, Ilex opaca, and Senecio tomentosus make 
their first appearance in this list, and Cornus florida, Taxodium 
distichum, Quercus Phellos, Myrica cerifera, Aralia spinosa, and 
Rynchospora inexpansa are decidedly more frequent here than in 
most of the preceding lists. (Most of the twelve species last men- 
tioned seem to be still more common in southeastern Virginia.) 
On the other hand, Pinus palustris, Gordonia, Taxodium imbri- 
carium, Cyrilla, Ilex glabra, Clethra, Pieris, Sarracenia, Tillandsia, 
Aristida, Rhexia Alifanus, Polygala ramosa, and Sabbatia lan- 
ceolata (as well as several equally interesting species noted less 
than three times and therefore not listed here) were now seen for 
the last time. Nearly all of these last are known or supposed 
to extend at least a short distance into Virginia, west of Dis- 
mal Swamp, but the rest of my route to Norfolk lay farther 
east. 
From Mackey’s Ferry the cars were taken across Albemarle 
Sound (and the 36th parallel) to Edenton, the county-seat of 
Chowan County, ona nine-mile ferry (since superseded by a trestle). 
From about this point what Prof. Shaler termed the Nansemond 
escarpment{ extends northward past the western edge of Dismal 
Swamp to the vicinity of Suffolk, Va. From Edenton to Norfolk, 
73 miles, I was east of this escarpment all the way, skirting the 
eastern edge of the swamp, and passing though a region quite 
different from anything else seen on this trip. It is rather flat, 
with prevailingly loamy or even silty soil, quite different from the 
sandy soil that prevails at corresponding distances from the 
coast most of the way from New York to New Orleans. There 
are many shallow swamps but apparently no ponds. The up- 
lands, or drier spots, were nearly all cleared and cultivated long
