harbour of New-York, a part of Long-Island and Staten- 
Island and a distant view of the ocean. 
The valley situated between the Newark mountain and 
the Bergen greenstone ridge is partly secondary, the rest 
alluvial. In the secondary division, sandstone in nearly hor- 
rizontal position, or waving with the surface is found al- 
most every where on penetrating the earth—and fine red 
and gray freestone alternates with shale at the sandstone 
quarries of the Passaic and Second river. ituminous 
‘coal in thin layers has been noticed, associated with argilla- 
ceous shale in many freestone quarries adjacent to the Pas 
saic; at the termination of the Newark mountain, at Spring- 
_ near Belville a tooth near two inches in length was recent- 
% foind on the freestone fifteen feet below the surface.— 
opyer is observed in many partsof the New-Jersey secon- 
dary ‘egion ; a vein of ore affording eight per cent of copper 
has keen recently discovered near the Pisshic three miles 
nortk of Bellville; the vein is now lost.—A rich mine was 
formerly worked on the property of Col. Schuyler a mile 
east of Belville, but the pasos of the shafts becoming too 
exprsive, the works were relinquished. The matrix 0 
talne fibres are collected in groups diverging from a poimt— 
the colour is emerald green with silky lustre—tufts are see? 
as a locality for oxide of titanium, but the only specimen 
found here was in a small solid mass of quartz. Not 13 
from Aquackinoek there is a copious mineral spring ; **
