102 TRANSACTIONS OF THE [ FEB. 29, 
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. 
Nore.—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 Amboy 
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 Prors. Britron, 
Bouton, and Martin. ;
