 By Abraham Gesner, M.D., F.G.S. 



(Abridged.) 



United States. — Commencing at New Jersey, in the United StateSj 

 the writer has examined nearly all the most interesting parts of the 

 coasts, as far northward as the northern part of Labrador. The 

 whole south-eastern side of New Jersey, where it borders upon the 

 Atlantic, to the extent of 100 miles in length and about 20 miles in 

 breadth, is composed of alternate strata of sand, greensand, marl, 

 and clay, some of the beds very highly fossiliferous. The land is 

 comparatively low, and slopes gradually from the high lands in the 

 rear towards the sea. A similar tract of country occurs in the 

 bordering State of Maryland, and, still further southward, in North 

 Carolina.
