Abstract
IN a paper entitled "Three Formations of the Middle Atlantic Slope," published in the American Journal of Science early in 18t\8,t a distinctive late Tertiary formation, well displayed on the Appomattox river in eastern Virginia, was defined and named after that river; and its principal characters, its distribution, its stratigraphic relations, and its probable age were briefly recorded.The formation was then known to consist of a series of predominantly orange-colored, nonfossiliferous sands and clays, resting .unconformablyupon.M.iocene and older formations, and unconformably overlain by the Columbia formation; it was known to expand southward, from a thin and discontinuous bed exposed in a narrow belt on the Rappahannock river, so rapidly as to form a terrane many miles in width on the Roanoke; and it was inferred to represent at least a part of the Orange Sand of Hilgard and other southern geologists.The several lines of research concerning the phenomena of the }Iiddle Atlantic slope recorded in this paper have recently been extended southward into the Carolinas, Georgia, Alabama, and Mississippi; and some of the results of the work are deemed worthy of publication.
