There is much in this series of exposures to remind one of the state of 
things on the James and Appomattox rivers. The material are much 
more heterogeneous but the clays occur in the same way, and it may 
have to be admitted that all the phenomena observed along the 
landward margin of the Potomac formation belong to one great period of 
disturbance. It may also be true that this period formed a part of the 
prolonged Potomac epoch, after the clays had been laid down but 
certain facts point to a much later, post-Miocene date, or there may 
have been true such periods are in Potomac time and the other much 
later.

Mr. Jones took ten views of the exposures last described, three of the 
high bluff back of Prof Goode's house covering it all to show the 
Archean contact, clay balls and lenses, and the various sand and gravel 
seams; and three on the east face of the cut [[insert]] A on Kansas 
Avenue [[/insert]] to the south of this farther up the hill. The most 
northerly of these is situated between the 2nd and 3rd wooden trolley 
posts, and the other two which slightly overlap are just below the first 
wooden trolley post, counting from the top of the hill where these posts 
are iron. The other 4 views cover most of the eastern face of the 16th 
cut beginning at the top of the hill nearest the plantlife and working 
down. They each embrace about 50 feet and were made as near as 
possible to just join each other and constitute all put together a 
continuous section.
