A little over i mile east of Marlboro, in the south bank of Hop 

 Brook, just east of the wagon bridge across this stream, is an 

 excellent exposure of the upper beds of the Wenonah sand and 

 the super jacent Navesink marl, the Mount Laurel not being rep- 

 resented. The section shown at this locality (130) is as fol- 

 lows, beginning at the base : 



1 30*. Black, micaceous and arenaceous clay, extend- 

 ing below the level of the brook. Fossils are abundant, 

 but all are in the condition of casts. In the upper por- 

 tion of the bed numerous quartz pebbles of the size of 

 peas are scattered throughout the clay, 6 feet.
