it to be a stream deposit) flowed, from, the northwest to the 

 southeast. These gravels are now 15 feet or so higher than the 

 outcrops of the highest Cretaceous beds in the vicinity. At 

 Ellisdale, a few miles away, the Cretaceous outcrops at altitudes 

 up to about 200 feet. Outcrops of the same beds farther north- 

 west would have been higher, and such outcrops northwest of 

 Jacobstown (now worn much lower) may well have been the 

 source of the Cretaceous material in the Jacobstown gravel, if 

 streams flowed to the southeast from them. 



From the present topography, it is inferred that Toms River 

 once had tributaries reaching northwestward past Prospertown to 

 Clarksburg. Either Toms River or Mullica River probably had 

 branches as far northwest as Ellisdale at least. On the supposi- 

 tion that the drainage was to the southeast, it is therefore not 

 difficult to account for the Cretaceous material in the Jacobstown 

 gravel. 



The gravel at 140 feet at Barnegat seems best correlated with 

 the Bridgeton formation, and if this correlation is correct, the 

 gravel a few miles south of Staffordville, at about 100 feet, may 

 be Pensauken. 



A few areas of gravel not on the line of the section merit 

 notice. One of these is south of Jacobstown, where gravels 

 which belong with those at Jacobstown decline to 170 feet or so 

 at Springfield, and to about 150 feet at Fountain Green and 

 Pointville. The gravel on Fearings Hill, west of Springfield 

 and Fountain Green, is an outlier of the larger areas at these 

 places. The gravel at Fearing Hill is regarded as a local phase 

 of the Bridgeton, the same as that at Jacobstown. 



West of Colliers Mills, there are areas of gravel at altitudes 

 ranging from 160 feet to 208 feet. The 208-foot hill is 1^ 

 miles northwest of Colliers Mills on the Hornerstown road, and 

 the 160-foot area a mile south of Colliers Mills. These remnants 

 are along the divide between the headwaters of Toms River and 

 Crosswicks Creek. The gravels here may be parts of a once 

 continuous sheet, or remnants of deposits on an old valley plain. 



Bordens Mill Branch, flowing past Colliers Mills, is a tributary 

 of Toms River, and appears to have headed formerly in the
