tions of sand and gravel just above the water, up to what is now 

 50 feet, more or less. 



In the valley of Clay Pit Creek, there is a good. deal of gravel 

 referable to this formation, especially near the Shrewsbury River, 

 where it is more than 30 feet deep in places. In the valley of 

 the larger creek west of Clay Pit Creek there is a considerable 

 body of gravel on the east side, and on the bank of the Shrews- 

 bury at its lower end; but it does not take on a distinct terrace 

 form at most places. Terraces are more distinct a mile and 

 more up the valley, at altitudes ranging from 50 to 70 feet. 



Due north of Red Bank there are distinct terraces at elevations 

 of 20 to 30 feet, but they are composed of Cretaceous beds 

 covered but thinly with younger sediments. Cape May sediments 

 appear, however, at the lower ends of Poricy and Nut Swamp 

 Brooks. 



In contrast with the phenomena of the smaller streams, there 

 are terraces up the valley o<f Swimming River and its main 

 branches for many miles. They are low, composed wholly of 

 Cape May sands and gravels in some places, while in others a thin 

 coating of sediments of this age covers the local Cretaceous 

 formation. The terraces rise progressively up stream, maintain- 

 ing a height of 20 to 40 feet above the channel of the river. 



Up Swimming River to the junction of Yellow Brook with 

 Hop Brook, the formation has considerable development on 

 both sides of the stream, forming low terraces or overspreading 

 the lower slopes of the valley, and reaching elevations of 40 to 

 50 feet. Just below the mouth of Hop Brook, the thickness of 

 the formation is as much as 20 feet on the north side of the 

 stream. Below Phalanx, the terraces are clearly correlated with 

 the 40-foot terraces about the coast, with which they are nearly 

 continuous. 



Hop Brook. — In the valley of Hop Brook, up to the junction 

 of its several principal branches, the formation is disposed as in 

 the valley of Swimming River, rising however to higher levels 

 (70 feet), with indefinite upper limits. There are more than 

 20 feet of well stratified gravel and sand at some places, while 

 in others the formation is represented by no more than a thin
