within the scope of this article, have already been considered. In 

 the Cape May region the Coastal District is represented by a narrow 

 strip along the ocean, locally known as "The Seaside," and a similar 

 strip along the shore of Delaware Bay, known as "The Bayside." 

 Both are alike in essential respects, although the beaches are absent 

 or exceptional on the bayside. North of Wildwood Junction the 

 seaside and bayside are entirely separated by the wooded interior, 

 but south of that point, as noted by Stone, the two converge and 

 unite to form a continuous belt of Coastal District country extending 

 clear across the lower third of the peninsula. 



The Interior District, as previously mentioned, partakes of the 

 nature of the Pine Barrens. The soil is typically a coarse sand of 

 the Norfolk type. It is similar apparently to the sands of the Pine 

 Barrens, but differs in its usually nlore humid condition and its 

 higher content of organic matter, a state of affairs doubtless due to 

 the extremely low elevation (rarely over 25 feet above sea-level) and 

 consequent proximity of the surface to underground water. The tree 

 growth consists predominantly of pitch pine (Pinus rigida), white 

 oak {Quercus alba), post oak (Q. stellata) and pig-nut hickory {Hichoria 

 glabra); of less frequent occurrence are Jersey pine (P. virginiana), 

 black oak (Q. velutina), Spanish oak {Q. triloba), black-jack (Q. mary- 

 landica), sassafras {Sassafras sassafras) and holly (Ilex opaca). 



The bogs of the Interior in their general appearance closely resemble 

 those of the Pine Barrens, but, with a few exceptions in the northern- 

 most part of the district, differ from the latter in the conspicuous 

 absence of the white cedar (Chamcecyparis thyoides). The usual 

 tree growth consists of red maple (Acer rubriim), sour-gum (Nyssa 

 sylvatica), magnolia (M. virginiana), sweet-gum {Liquidamber 

 styraciflua) , Spanish oak {Q. triloba) and willow oak {Q. phellos). 

 The lower scrub growth consists largely of Clethra alnifolia and Azalea 

 viscosa. In clearings the dominant plants are Woodwardia virginica, 

 Juncus (tall species, probably canadensis) and sedges (Eriophorum 

 virginicum and Rhynchospora alba); with these are asseciated lesser 

 numbers of such plants, as Lilium superbum, Aletris farinosa, Ble- 

 phariglottis blephariglottis, Pogonia ophioglossoides, Drosera longifolia, 

 Polygala lutea, P. cruciata, Rhexia virginiana, R. mariana, Asclepias 

 pulchra and Oxypolis rigidior. 



South of Wildwood Junction the character of the vegetation under- 

 goes a gradual change, assuming more the aspect of the vegetation 

 which is characteristic of the lowland woods of the Delaware Valley 

 and Coastal District. The pitch pine becomes a less important
