No. 1477 A7.— Exposures on the Pennsylvania side of the Delaware 
River, a little above Sparrowbush and opposite the ninetieth New York 
mile-post on the Erie Railroad. These are eoarse arenaceous blue shales 
and sandstones, some layers being of concretionary structure. Dip 
about 8°, 25° west of north. Fossils not common, but in a rather 
blocky shale several Hamilton species were found.

No. 1477 A4. — On the western bank of the Delaware River, just 
below the New York, Lake Erie and Western Railroad bridge, are 
shales and sandstones which belong in the Chemung of Prof. White. 
The course of the river at this point is nearly from north to south, and 
not far below the bridge the dip on the edges of the layers is from 5° 
to 10° nearly due north. A little farther south the dip is only slightly 
to the north, while still farther south, where the river strikes the almost 
vertical cliff, the dip is greater toward the north. It is probable that 
this dip on the face of the layers to the north does not represent the 
greatest dip of the rocks at this locality. Some of the joints in the 
rock enter the river at about 32° east of north. The exposure consists 
of thin, blue sandstones, alternating with bluish, rather arenaceous 
shales. There are concretionary layers at irregular intervals and some 
layers of sandstone with an undulating or warped structure. Fossils 
are comparatively rare in the shales, and still more so in the sandstones. 
The blue sandstone is quite similar to the blue quarry stone along the
