volved with the moraine. On the east side of the neck, or in other 
words on the west side of Hempstead Harbor, these exposures may 
be seen in road cuttings and on the shore, especially in the vicinity 
of Mott’s Point. Ferruginous shale and concretions, in all respects 
similar to the material found on the opposite shore of the harbor, at 
Sea Cliff and Glen Cove, are abundantly represented, both in con- 
nection with the Cretaceous exposure and as scattered morainal 
material. It wasin these concretions and fragments of shale that the 
fossil plant remains were found. So far as ] am aware there is no 
previous record of fossil plants having been discovered at this local- 
ity, although their occurrence was to be expected, as it is directly 
on the line of strike between Glen Cove to the east and Elm Point 
on Great Neck to the west, at both of which places there are out- 
crops of Cretaceous clays, accompanied by ferruginous shales con- 
taining leaf impressions and a knowledge of these conditions was 
what led to the exploration of Manhassett Neck. 
I am indebted to Mr. A. E. Anderson for the opportunity to 
examine and describe specimens in his possession and to Mr. 
C. Veatch, Mr. H. S. Shimer and Miss Florence Henry (now 
Mrs. H. 8. Shimer), for assistance in the field. 
Il. FOSSIL FLORA OF THE NORTHPORT CLAYS 
GENERAL CHARACTER OF THE PLANT-BEARING DEPOSITS 
The beds containing fossil plants in the vicinity of Northport are 
located on Little Neck, which forms the western shore of North- 
port Bay. They consist of stratified clays and sands, of Cretaceous 
age, overlain by more recent sands and gravels and a limited amount 
of glacial till. The strata are exposed on the eastern side of the 
neck, where the clay and sand has been excavated for commercial 
purposes. There is some indication of disturbance in the deposits 
as a whole, as if they had been subjected to lateral pressure, but a 
general S. E. dip is apparent in the portion exposed. Plant 
remains are abundant in certain layers, but as a rule they are either 
fragmentary or else they are contained in fine, sandy clay, from 
which specimens in good condition are exceedingly difficult to 
obtain.
