Although it is probable that amber is far more common in the 
Cretaceous deposits of the eastern United States than is generally 
upposed, as indicated by the relatively large amount that was 
found in the limited exposure at Kreischerville, the actual records 
of its occurrence are few and the localities mentioned are widely 
separated. It has been found at Cape Sable, in Maryland, Glou- 
cester county, N. J., Martha's Vineyard, and at Northport, Long 
Island. At the latter locality it was discovered by the writer, but 
has not been previously recorded, 
Fic. 15. a, rane matrix, containing amber ; 4, impure amber; <, @, ¢, amber 
drops or ‘‘ tears’’ ; 7, large specimen of clear amber. 
The problem of the origin of the amber is of considerable in- 
terest from the botanical point of view. At Cape Sable it was 
found included in = interstices of a log of lignite, which was 
determined by Dr. F. H. Knowlton, of the U. S. National Mu- 
seum, to belong to an extinct species of Seguota, the genus to 
which the giant trees of California belong, and at Kreischerville 
it occurs in close connection with the leafy twigs of Seguota het- 
erophylla Vel. and S. Reichenbachii (Gein.) Heer. The amber of 
Japan is also said to be associated with the leaves of a Seguoza. 
Other remains of coniferous trees which occur in the Kreisch- 
erville clays are Widdringtonites Reichii (Ett.) Heer, Juniperus
