continuation of the ISTew Jersey beds, they must be explained as 

 follows: either the original beds have been torn apart by the ice 

 which bore down on them, or else they have been deeply eroded 

 by the currents wliieh deposited the overlying sands and gravels. 

 The writer favors the latter view.

Kext to the church at Kreischerville is a bank of stratified sand 

 standing some 40 feet back from the road. It appears to have 

 been dug away considerably, but Mr Kreischer informed me that 

 there was once a large mass of clay at this spot which was sur- 

 rounded by the sand. To the north of this near the shore is a 

 bank of blue stoneware clay overlain by yellow laminated sand, 

 and southeast of the church is a similar bank, but the clay is of 

 a more sandy nature. A third opening is opposite Kilmeyer's 

 hotel at Kreischerville, and from this a yellow mottled fire clay is 

 obtained. This latter bed is overlain by about 20 feet of sand and 

 yellow gravel and underlain by a white sand. 



A fourth opening on the shore is in a blue clay. It has always 

 been an interesting question as to what extent Staten Island was 

 underlain by the Cretaceous formation; the following record of a 

 well bored for Bachman's brewery at Annandale, S. I., seems to 

 throw some light on the subject. At a depth of 200 feet a bed 

 of yellow gravel containing shells was struck. The gravel was 

 36 feet in thickness and beneath it was a bed of clay 10 feet thick. 

 The latter was of a white and blue color and was said to resemble 

 a fine pottery clay.
