"It is just as plain as anything can be that the oil geologists have next to nothing about under- ground correlations. It is all on the basis of lithology and even then it is very poor. As I told them they need a paleontologist, and they need me in some lady. But in a paper read by O. White clear cut forth that the Bend is a deep series, and that it contains Miss. and Penn. The lowest Bend a Hard Shale has 35 to 40 species and these are of the high Miss. i.e. the Tennesseean. He does not make it clear how high, but apparently it is more up and further in the Chester though of a different sea-way. He connects it lower Bend with the lower 700 feet of the Camp, and White does not seem to agree with any correlation; tho other 700 feet being apparently Penn. The lowest Bend has Smialites strictus and A, and it was one of these fossils that lead J.P. Smith to connect the Ford with the high Miss. In this he is wrong according to Sirty. The Marble Falls has 105 species and the Smithwell 35, both for the same. The latter is marked by Hadrphyllum aplanatum. In the former from Paralepocrinus and Hyatt's large conutilis. Here also the species identified by Sirty in Paris Burnet-Ian data Folio. Also Tegalifera
