\ RECENT DISCOVERY OF AMBER ON STATEN 
ISLAND 
During the months of October and November of last year, while 
he writer was engaged in collecting fossil leaves in the Cretaceous 
‘lays at Kreischerville, Staten Island, there were found, rkisnts 
vith the leaves, numerous specimens of amber. The overy 
vas briefly recorded in the Proceedings of the ee oe 
Association of Staten Island for November 12, 1904, and was

Amber in the Eastern United States,’ which was read at the

December. s paper will appear in full, in a forthcoming 
umber of the re erican Naturalist. The discovery aroused 
onsiderable interest and the preparation of the following brief

ersey, as evidenced by the fossil plant remains found in them. 
At Kreischerville they have been extensively excavated for eco- 
omic purposes and utilized in the manufacture of fire brick, terra 
otta, etc. 
The amber occurs in a stratum or bed, characterized by layers 
nd closely packed masses of vegetable débris, consisting of leaves,
