Character of Materials.—The materials which compose the Talbotformation consist of clay, peat, sand, gravel, and ice-borne boulders(Plates XIV, XVI, Fig. 1, XVII, and XVIII). As in the Sunderlandand Wicomico formations, these materials grade into each other bothvertically and horizontally, and the same tendency toward a bipartitedivision of the coarser materials below and the finer materials above ispresent in the Talbot as in the others.

There is, on the whole, much lessdecayed material than in the three preceding formations and the absenceof this gives to the formation a younger appearance. Cross-bedding isvery common. In the western portion of the area, throughout the Poto-mac and Susquehanna valleys, the Talbot deposits frequently containlarge ice-borne boulders. These are also common on the surface andwithin the body of the same formation on the Eastern Shore.
