Immediately west of the Bayou at Steam Shovel, considerable excavations have been made in a hillside exposing a vertical section of at least 50 feet. The entire length of the exposure is about 100 yards. In this distance the component strata vary greatly in thickness, so that in order to present an accurate view of the beds a sketch of the whole cliff would have to be given on a rather large scale. In a general way, however, the sequence of strata, beginning above is as follows: 1. Yellowish sand and loam 5--8 feet. 2. Light pinkish clay, 4 feet. 3. Brownish yellow sand with pellets and lam inae of pinkish clay... 2--5 feet. 4. Jet black clay shale 6--9 feet. 5. Brownish black micaceous sand with oblong concretions 10--15 Beneath No. 5 at the western end of the exposure occur: 6. Green sand 2 feet. 7. White sand 3 feet. 8. Black tough clay 2 feet. This is probably the most extensive outcrop of Tertiary west of the Ouachita River. Though some time was spent here not a trace of a fossil was found in any of the beds. The sands and clays are alike being removed and used along the railway for ballast; and in this county and Lafayette, large blocks or chunks of bed No. 4 can be seen strewn along the track. These blocks in weathering break up in precisely the same way that fissile Paleozoic shales do and one would almost suppose without examining closely that they had been obtained from the roof of some coal mine. The great resemblance of these shales to those described by Hill at the mouth of L'Eau Fraiche on the Ouachita may prove to be of more than passing interest. Lone Hill.--In going westward from Steam Shovel towards Texarkana, the railway runs generally through slightly depressed valleys, but on either side there are rather...
