 spicules. As these species are the same, or rather the group- 

 ing of them, as are living on the coast we may consider this as 

 made up the recent forms. There is also i^resent besides quartz 

 sand, which makes up the mass of the soundings, broken crys- 

 tals of magnetic oxide of iron and transparent green crystals of 

 hornblende showing that they come from the Palisades of 

 ISIew Jersey or the Trap rocks of Connecticut, most likely of 

 Connecticut, for this is the way north or somewhat to the east, 

 the ice came which formed the moraine on the coast. The 

 microscopic organisms are not those of the Newark bay as 

 they are not of brackish or fresh- water origin as those are, 

 showing the " fiord " is not a continuation of Newark bay but 

 rather of the Hudson River. This may serve as a contribu- 

 tion to the knowledge of the Hudson River " fiord."
