216 Geology, ire. of Malhay, L. G. 



in alluvion*) An interval of shingle having taken place for 

 fifty yards, a nearly pure quartz follows, much fractured. 

 It retains the south-west direction and the south-east or 



3 



vertical dip, and extends for 100 yards, protruding from the 

 contiguous hillj whose summit is composed of it. — Now 

 aud then it is seamed by a dark quartz, mixed with mica: 

 the walls of the seam being \ery ill defined. 



Close to this, (proceeding eastward along the beach,) 

 covering and intermixing with it, is a horizontal stratum of 



of quartzose puddingstone, with small scales of white mica^ 

 It soon passes into the form of the calcareous conglome- 

 rate and contains a few shells. It is only an insulated frag- 

 hient, ten feet broad, by five in height, probably incum- 

 bent on the vertical quartz, which is nowresumed (or twen- 

 ty yards, when it disappears under the shingle. 



One hundred yards to the east, there is a low tongue of 

 land, about three hundred yards across, and two hundred 

 long. Its beach is wholly occupied by the dark limestone, 

 its strata dipping in long undulating curves, or in short bro- 

 ken masses in every imaginable direction. This limestone 

 possesses a few shells, and has many knotty protuberances, 

 six inches high, by a foot or more in diameter. Their sur- 

 face and interior are marked with indistinct appearances of 

 the capillary sea weed, w^hich, fixed to some rock, streams 

 in the tide. — Large globular concretions are abundant, sim- 

 ilar to those in the white limestone of Lake Huron, and 

 of composition similar to that of the containing rock. 



In the rear of this projecting point, and somewhat to the 



east, is a gentle alluvial ascent, crowned by broken ledges 



of calcareous cont^lomerate, passing into sandstone; 



themselves again sumiounted by a steep round-backed 

 hill. 



Passing eastward a very short distance, we find the sea 

 encroaching gradually on this alluvial ascent until it bathes 

 the foot of iis congjomerate ledge, which now, two hundred 

 feet high, forms the immediate shore, fronted, and half 

 buried by the usual pile of ruins. Its west end is not far 

 from the last of the confused layers of limestone, where it 

 becomes now and then interleaved wilh a browner and 

 somewhat crystalline hmestone ; and still nearer, witli the 

 green variety of the conglomerate so closely resembling 

 grey wacke, both rocks observing the accidental direction 

 of the accompanying strata.
