half a mile of the Highlands and extending in a semi-circu-

hibits in its direction and the aspect of its summits a proo 
of the correctness of the above positions. The extensive 
valley situated between the greenstone semi-circle and the 
Highlands presents much fresh water alluvial—many of the 
small hills of this tract have no rock in place—the alluvial 
plain bordering the Passaic is in general extensive ; in some 
places four miles in width—peat is observed in several oe 
ces between the source of that river and the little falls; 
considerable quantity is cut in this valley adjacent to be 
Newark and Morriston turnpike ; the earth had been pene- 
trated six feet without finding the bottom of the strata. The 
level tract called Pompton plain near twenty miles in cir- 
‘cumference and environed by mountains presents a deci- 
ded fresh water alluvial—strata of gravel, sand, and clay,
