6 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 
referable to the Raritan and the upper red and Бий sands to the 
Cliffwood. 
The phenomena of cross- and lenticular-bedding is best exemplified 
in the Androvette pit, and some of the sections there exposed also 
afford the best examples of the stratigraphic relations between the 
several deposits represented. The most extensive vertical section in 
this pit is shown in Plate 1. The contact between the Raritan and 
Cliffwood formations is comparatively well defined and the eroded 
surface of the latter, together with the overlying unconformable 
Pensauken sands and gravels, are finely exposed. Boulder till is not 
present in this section, which underlies a limited unglaciated area. 
In the Drummond pit the Cretaceous deposits are almost exposed 
at the surface of the ground. The Pensauken sands and gravels 
are lacking, having been entirely eroded by glacial action, but they 
are represented, to a certain extent, as more or less conspicuous con- 
stituents of the till, which rests in a thin layer directly on the Cre- 
taceous deposits. These latter here consist of relatively thick clay 
strata, in which sandy layers are not conspicuous features, and cross- 
bedding or other indications of the action of running water are 
wanting; but well defined faulting and slight arching or folding, 
evidently caused by the weight and thrust of ice, are quite apparent. 
A view of a portion of this pit is shown in Plate 2, where the arching 
of the strata, in a gentle anticline, may be noted. These clays are 
located at a considerable elevation above and to the south of those 
in the Androvette pit, and as the normal dip of the strata is towards 
the southeast they should, theoretically, represent a higher and more 
recent geological horizon than the latter; but the deformation and 
disturbance to which they have been subjected renders it somewhat 
hazardous to venture any positive opinion on this point. 
Occurrence and General Characters of the Plant Remains.—The 
only plant-bearing beds belong to the Raritan Cretaceous deposits, 
and plant remains of one kind or another are present in most of the 
layers. They are sometimes represented merely by finely comminuted 
charcoal or lignite, but larger fragments and branches and logs 
of lignite, often charred on the exterior and impregnated or coated 
with pyrite, are more or less abundant. In many of the latter amber 
occurs in the interstices. In addition to the charcoal and lignites the 
remains also include irregular fragments and drops or “tears” of
