Sound, about four miles northeast of 

 Woodbridge, through the northern 

 part of that village, and then across 

 the hills to Metuchen, and onwards to 

 the Raritan, which it crosses in the 

 southern j^art of the city of New Bruns- 

 wick, and thence onward to Ten Mile 

 Run and Kingston, and thence along 

 the valley in which the Delaware and 

 Raritan Canal runs on the south of 

 Princeton and Trenton to the Delaware 

 River. 



The outcropping edge of these 

 formations is thin, so that in many 

 places the underlying red sandstone 

 is exposed in the inequalities of the 

 surface, or is easily reached in digging. 

 This, of course, must leave the edge 

 somewhat irregular, and in one place 

 in Middlesex County, north of the 

 Raritan, the red sandstone rises in a 

 considerable hill south of this line, and 

 is entirely surrounded by the white 

 cla3^s of this later formation. 



The Raritan clav beds, with their 

 intermediate beds of sand, which are 

 the lowest in the series here described, 

 are retained as a ]3art of the Cretaceous 

 series. Stratigraphical relations war- 

 rant this.. The very few fossil shells 

 which have been found in them are of 

 estuary forms, and are thought by some 

 paleontologists to bear a close resem- 

 blance to those of the Wealden or 

 Jurassic age. The greensand and in-
