THE MAGOTHY FORMATION. 



Certain beds of clay and sand alongf the south shore of Raritan 

 Bay have called forth considerable discussion of late years^. 

 These beds were in large part, perhaps entirely, included by Cook 

 in his "plastic clay" series, being included in his "clay and 

 lignite" division at the summit of the series.^ The name Cliff- 

 wood has been applied to these beds by Kiimmel.^ The beds are 

 not always of clay, sometimes being largely arenaceous, as at 

 Prospect Grove, where 4.0 feet oif white sand, with searns of black 

 lignite and thin beds of black clay (becoming thicker and more 

 numerous towards the base of the section) occur immediately 

 beneath the Merchantville clay-marl of the Matawan series.
