In the same road, about four miles northwest of Melrose, at Simpson's

 five feet, containing shells of Scutella suhrotundaf, Cardita, sp. ind.?, etc.; very 

 friable greensand shell marl four feet; shaly marl, with a two-inch parting of 

 hard glauconitic clay, two feet; altered greensand shell marl three feet. 



On the road from Marion to Nacogdoches, eight miles southeast of Nacog- 

 doches, is an exposure of greensand shell marl, probably a continuation of 

 the bed just described. 



On Aaron's Hill, just west of the town of Nacogdoches, was observed the 

 following section in the cut made for the public road: 



A. Soil (sandy clay) . 2 feet. 



B. Mottled clay 6 feet. 



C. Gray sand 8 feet. 



D. Greensand shell marl 20 feet. 



E. Red clay bottom soil 2 feet. 



F. Greensand shell marl to bed of creek. 



About one-fourth of a mile north of the office of the Lubricating Oil Com- 

 pany was seen a stratum of greensand marl in the bed of a small stream. 

 When the marl was chopped with a hachet the red-brown oil exuded and 

 floated off on the surface of the water. On the hillsides adjacent are rem- 

 nants of the iron sandstone material.
