These deposits have for the present been assigned to the Orange Sands. Detailed sections have been made and are now being studied in relation to their proper position in the general section.

In the neighborhood of Beaumont and northward to Village creek, in Hardin county, there are some deposits of dark blue laminated clays and sands overlying a heavy deposit of gray clay. These probably belong to the later Quaternary and are of the same age as Hilgard's Port Hudson group. No fossils were found in these clays. The country is nearly flat, sloping only at the rate of two or three feet to the mile throughout the whole thirty-five miles, and very few sections could be obtained. The total thickness of these clays will not exceed thirty feet.

PLIOCENE.

No recognizable deposits of this period have been found along the line of any of the sections.

MIOCENE.

The series of deposits named Fayette Beds by Dr. Penrose, and de- scribed by him in the First Annual Report, page 47 et seq., have been mostly referred to the later Tertiary or Miocene age.

These deposits overlie the upper division of the Eocene, are practically conformable to these beds and consist of thinly laminated blue and brown clays and sands containing great quantities of selenite crystals, massive brown sands jointed in various directions with crystals and masses of gypsum in the joints, black, gray, pale green, brown and white clays. These form the base of the deposits and are overlaid by massive and laminated gray sandy clays and clayey sands containing fragments of leaves, gray sands and sandstones containing quantities of opalized wood, leaves and stems and leaves of palms, etc., diatomaceous earths and lignites. In Polk county the gray sandstones are fossiliferous and are underlaid by a thin deposit of light gray fossiliferous limestone.

Areally these beds succeed the upper deposits of the Eocene and have their northern boundary, so far as yet defined, in a general northeast and southwest direction, beginning on the east side of Cherokee county, near the junction of the Atoi creek and Angelina river, passing across Cherokee about a mile south of McBee school house, and thence a little south of Alto to the Neches and crossing into Houston county about five miles south of Weches. From this point the boundary runs west for a few miles and then turns rapidly towards the south, passing Crockett about half a mile south of the town. It then turns west for nearly four miles and thence in a nearly southern direction almost parallel to the course of the Trinity river as far as Alabama Bluff, at which place it crosses into Leon county.

The southern boundary of these beds have not yet been definitely
