and the shaly rocks at the junction assume the color and splintery- 

 fracture of decomposed trap, lines were observed in the adjoining solid 

 basaltic rock continuing, as it were, those of the stratification of the 

 Jurassic shales and harder bands, as if the whole of the latter had been 

 melted w situ. 



The appearance of bedding in the solid crystalline trap could 

 only be traced for about 50 feet horizontally, and was not observed where 

 this trap underlies a capping of strong sandstone on the east side of 

 the same ravine in which the above section occurred. 



The beds which fold round and dip in all directions from this 

 intrusion consist of impure grey and dun-colored limestone, strong 

 blue and greenish-olive calcareous grits and cherty bands, with oolitic 

 blotches (resembling somewhat the golden oolite south of the Keera). 

 Besides these there are many bands of dark-gray and rusty shale 

 overlaid by coarse, pale red sandstone alternating with gravelly layers 

 and gray sandy shales and flags. 



On the outer slopes of the hiUs, coarser and redder sandy beds, 

 still with shale bands, and a few calcareous shelly layers prevail, and are 

 found to contain numbers of the usual fossils of the lower group, some 

 few of which occur in nearly all the beds of this locality. They also 

 contain some Ammonites, one of which is a Stephanoceras allied to 

 Macrocephalus, and another is Harpoceras serrigerum. Associated with 

 these outer beds are trap dykes and intrusions between the planes of 

 stratification.

 stream, where it has cut a clifi' close to the village, an oblique section 

 of the rocks consisting of thick dark shales and flags between stron"- 

 sandstones is exposed.
