sea-sbore line, extending from the mouth of the Gulf of St. Law- 

 rence to Alabama; and a subsequent disruption and up-shove against 

 this steep shore, along perhaps its whole extent, certainly along an ex- 

 tent of seven hundred miles. Along this whole line the once so-called 

 " Hudson Kiver Slates" (the No. 3, of the Pennsylvania Survey) are 

 over-ridden by and abut against the Hudson River Slates proper 

 (Taconic Slates, or No. 1, of the Pennsylvania Survey). Whether 

 the Philadelphia and Baltimore System will obtain hereby, at last, its 

 explanation, we can only conjecture. But certainly its rocks and 

 minerals resemble some of the members of this " Quebec Group" or 

 Taconic System ; and there are evidences along its northwest edge, 

 from Trenton past Philadelphia, of a great fault, in the place where 

 we should be inclined to look for one.
