We had the great fortune to rediscover the Pamunky bone-bed on the 
Good Hope road. It is just above the curve in the road in going up from 
the last named point, the gutter has been washed but laying it bare 
again. Some four feet of it are eclipsed below the road bed. It is overlain 
by the Chesapeake 20 feet in thickness, and fine contacts were 
obtained. 
Recent excavations along the road from Good Hope to the new bridge 
have created magnificent exposures of LaFayette resting on the 
Miocene. This in turn rests on the Potomac sand and these on the clays 
and all these contacts are visible in going down the hill to the north. We 
took one of the new cut roads that strikes Pa. Ave. Extended pretty well

the hill. The material here cut through is very puzzling. It is not typical 
Potomac clay, but is mottled and streaked like the nondescript material 
seen in some other places. It also has suspicious veins of pebbles 
suggesting Columbia. 
We went up the Avenue to the plant bed. They have been clearing away 
the sloughing and exposed the south side again, especially below. Here 
the Potomac clay grades off insensibly with sand of the same red color, 
showing that there is not always unconformity between them. We found 
clay seams but no plants, as it was late and we were in a hurry. They 
have now cut nearly through the hill and got out of the Potomac and 
Chesapeake into the Lafayette gravels.
