Crossing to the Connecticut valley we find this order reversed ; 
on the eastern margin of this area the coarse conglomerates 
again occur, together with an abundance of all the other proofs of 
shore conditions we have mentioned; on the western margin the 
rocks have been formed of sand and mud deposited at a distance 
from the shore, and are without sun cracks, footprints, etc.; these 
beds correspond with the sedimentary rocks in the PESARA 
along the western shore of the Hudson. From these facts it 
seems perfectly justifiable to conclude that the variegated con- 
glomerate bordering the New Jersey area on the west, corres- 
ponds in character and position with the coarse conglomerate 
occurring along the eastern margin of the Connecticut River 
region, thus mapping out portions of the astern and western 
shores of the estuary in which the Triassic rocks were deposited. 
Thirdly. The occurrence of an outlying mass of Triassic beds 
in the towns of Southburg and Woodbury, Conn., lying between 
the two great areas, also favors the conclusion that the sandstones 
and shales of New Jersey and the Connecticut valley were once 
united. This little oasis in the valley of the Housatonic, is but 
six or seven miles long by two broad, and is separated from the 
Connecticut valley area by fifteen and from the Hudson by forty 
miles of crystalline rock! 
Fourthly. The topographical features along the western dicia 
of the New Jersey area and the extension across the Hudson of 
the line of bluffs which border the formation in New Jersey, as 
stated on page 21 of the writer’s previous essay (page 241 of the 
Annals), also indicates that the Triassic rocks of New Jersey at 
one time followed the course of this old shore line and extended 
eastward of the Hudson. 
Fifthiy. The striking analogy that exists in the affadeeticht of 
the hills of trap found in these Triassic areas was also pointed 
out in the paper mentioned above. Nearly all the igneous rocks 
found in New Jersey and the Connecticut valley have been formed 
as sheets of molten matter intruded between the layers of sedi- 
mentary rock and have cooled and crystallized in that position. 
In the Connecticut valley these sheets of trap dip eastward at the 
same angle with the sandstones and shales, and present a bold 
escarpment to the westward; the ends of the long ridges are
