III. The Piedmont District. 



The Piedmont Region of New Jersey consists of a rather narrow 

 belt of gently to moderately rolling country formed almost entirely 

 by the red shales and sandstone of Triassic age, but in Pennsylvania 

 it widens rapidly and includes rocks of many kinds. All of these 

 are thoroughly consolidated and, with the exception of the Triassic 

 series, are more or less extensively metamorphosed. Topographically, 

 the Piedmont possesses considerable relief, but is less rugged than 

 either the Appalachian or Highland Regions, the highest elevations 

 rarely exceeding 600 feet above sea-level. This, however, is sufficient 

 to produce relatively swift-flowing streams and thereby to ensure 

 good drainage. As a result, permanently moist tracts are of limited 

 extent and are largely restricted to soggy patches about spring-heads 

 or to seepage depressions on the level tracts bordering the streams. 



The soils of the Piedmont are residual. They are highly variable 

 in composition and texture in accordance with the varied nature of 

 the underlying rock formations. All agree, however^ in having a 

 loamy texture, the silt-clay content never, according to the published 



^ (c) Possibly occurring throughout the Highlands, but definitely reported 

 only from Fort Lee on the Hudson, where the Highlands meet a narrow arm 

 from the Coastal Plain. 



(d) Recorded under " co))ipaclus" in the Now .Jersey Report. 



(e) From Fort Lee only, probably stragglers from the Coastal Plain. 



(/) No actual records from the Highlands, but are common, widely-distributed 

 species, which doubtless oc(!ur there.
