He was assisted in many ways by Air. J. R. Alacfarlane, of 
Pittsbnrij, and Mr. R. R. Hice of Beaver, Pa. 
In the course of the week devoted to the excursion many 
points of interest in stratigraphic, economic, glacial and phys- 
iographic geology were seen. The main features of the phe- 
nomena observed clustered about two points. The first was the 
high level terraces, covered by gravels, of the !Monongahela, 
Alleghany and other streams, and the connection of these ter- 
races with a preglacial river flowing northward into the Lake 
Erie basin by way of tjie present Beaver valley. The second 
was the detailed, stratigraphy of the Permo-Carboniferous 
rocks and the great distance over which some of the thin mem- 
bers of this column could be identitied.
