tion, at an elevation of some twenty feet above the base of the ridge 

 and with a dip towards it. 



In view of all the facts now in our possession, it seems as if the 

 isolated and limited exposures of cretaceous strata mentioned must 

 indicate a large and probably continuous bed of similar material 

 throughout the entire area, as previously predicted. 



As far as the exposures at Kreischerville are concerned, it was 

 my original intention to include a description of them, with such 

 facts as were known, in this paper ; but within the past three weeks 

 new and Interesting discoveries have been made there which have 

 rendered it advisable to postpone any detailed account of the region 

 until these new discoveries have been more fully worked up and 

 examined. 



Note. — Since this paper was prepared, the United States Geological Survey 

 has issued Bulletin No. 82, entitled "Correlation Papers — Cretaceous," by 

 Chas. A. White. The author divides the New Jersey cretaceous strata into 

 "marine" and "non-marine," and in the latter division places the Araboy 

 and Staten Island clays, mostly on account of the lack of conclusive evidence 

 to the contrary. With the facts now in our possession, however, this view 

 seems no longer tenable, and this method of division should be abandoned. 



At the close of the paper remarks were made by Profs. Britton, 

 Bolton, and Martin.
