The colour of the green mineral, after washing, is but little 

 changed. 



The upper portion of the marl bed of Mr. Conover is less valu- 

 able in greensand, as will be seen by the following analysis :

The amount o^ potash which it contains, is 7-3 per cent. 



Chapel is upon a flat hill or table land ; and a well near this 

 place dug seventy-four feet through the upper strata, did not reach 

 the marl, though it shows itself, near the surface, in all the sur- 

 rounding low grounds, where it is of very good quality. 



The hills are sandy and strewed with fragments of the con- 

 glomerate, which is also in place, being quarried half a mile 

 south of Chapel. 



The timber growth on the hills contains a pretty large mixture 

 of cedar. 



The marl extends from Chapel north towards the Bay shore, 

 as far as the permanent land itself. Richard Wallin has reached 

 it in digging a well ; it was seven feet below the surface, and was 

 penetrated fourteen feet. Mr. Anderson, within half a mile of 

 the shore, also has a marl pit. The dark green grains abound in 

 the sands of the beach, and every where as we pass along the 

 road from Chapel to the Bay shore, towards the east. 



Bay Shore and Cliffs of JVevesink Hills. — The marl appears to 

 extend to within a short distance of the Bay shore near Compton 

 creek. The first cliffs which we meet with on going along the 

 shore to the east, exhibit a dark stratum, chiefly clay and siliceous 

 sand, with mica, containing very little of the marl, and often a 

 considerable share of copperas, which shows itself upon the sur- 

 face, in the state of a yellow efflorescence. Tracing the base of 

 the cliffs, we see this stratum slowly rising and forming the lowest 

 bed visible along the beach, nearly the whole way to the termina- 

 tion of the highlands at the Telegraph hill. 



In some places the cliffs have a height of fifty or sixty feet,
