side we behold, within a few hundred feet, and dipping in the 

 same direction and at the same angle, the northwestern edge of 

 the red shale. 



The relation of the calcareous conglomerate to the underlying 

 stratum is well shown on the route from Pepack to New German- 

 town, east of the Lamington river. The rock is generally a sili- 

 ceous conglomerate or coarse arenaceous sandstone, with some 

 thin layers of shale, all dipping at a moderate angle to the west 

 and southwest. 



At New Germantown, a little north of the village, the red shale 

 is seen dipping westward, changed to a greenish-gray colour 

 near the brook by its vicinity to a narrow dike of trap. 



At the same spot an argillaceous limestone occurs, also dipping 

 westward and occupying a place in the strata a little lower than 

 the red shale nearer the town. About a quarter of a mile to the 

 northeast of the bridge over the brook, are several quarries in a 

 field east of the road, exposing the calcareous conglomerate, 

 which is here used for burning into lime. Some of its pebbles 

 are very large, consisting of limestone of various colours, a small 

 proportion only belonging to other rocks. The cement is also 

 highly calcareous. The dip of the stratum at this place, is west 

 5" south, at an angle a little exceeding 20°. 



Half a mile northeast from this is another quarry more recently 

 opened, exposing a calcareous conglomerate similar to that in 

 Ogden's quarry, next to be mentioned. The beds have a gentle 

 dip towards the southwest. 



Lying about three quarters of a mile still further to the north- 

 east, is Ogden's quarry, at present the most extensive in the tract. 

 The cement uniting the pebbles is at this spot generally very 

 calcareous ; it is of a reddish colour, and some portions are highly 

 stained by the brown matter of the red shale. The aspect of the 

 rocks is singularly diversified, owing to the variety in size, shape, 

 and colour of the imbedded pebbles. Specimens may be obtained 

 here susceptible of a beautiful polish, and affording an ornamental 

 marble of considerable beauty and novelty of appearance. The 

 dip of the beds in this neighbourhood is eastward, at an angle of 

 20°. The conglomerate is not found beyond Ogden's quarry, a 

 high ridge to the east seeming to arrest it in that direction. 



About two and a half miles to the northeast, on the Lamington
