 sti'iated surfaces of the northeastern counties of Pennsylvania, 

 and the adjacent districts of New York, proving, that while the 

 scratches which abound on the summits of all the mountain 

 ridges in that part of the Appalachian chain observe a nearly 

 north and south direction, answering to their prevailing course 

 throughout New England and the countiy of the lakes, those on 

 the sides and bottoms of the valleys obey, with remarkable 

 fidelity, all the local deflections which a body of moving waters 

 would encounter among the ridges and valleys of this entangled 

 range. In the neighborhood of the Wyoming valley, the sum- 

 mits of the mountains, elevated about two thousand feet above 

 the sea, and one thousand five hundred above the valley, are

 other directions conforming to the course whicii any obstructed 

 inundation would pursue. Thus, near "Wilkesbarre, the northern 

 flank of the southern mountain, which was here exposed to the 

 full brunt of the inundation, exhibits the grooves with a direction 

 compounded of the general meridional one, and that of tlie de-
