Safford's Final Report on the Geology of Tennessee, 1869. Later (in 1866) Niles and Wachsmuth studied the upper beds, which had become known as the Burlington limestone, and were led by the c rinoidal remains to regard the two divisions as two independent for- mations, which the}^ designated as the Lower and Upper Burlington, a subdivision which still holds. Safford's final report on the geology of Tennessee did not appear until 1869, having been delayed by the incidents of the civil war. It was accompanied by a col- ored geological map of the State, and a geological sec- tion, un- co 1 o r e d, extending from the Unaka chain on the cast of the Mississippi, and giving, on the whole, a very comprehensive and easity un- derstood idea of the physical geography and geology of the State, as well as its eco- nomic resources. He here called attention to the fre- quent recurrence of the same formation, or series of for- mations, met with in cross- ing East Tennessee, and accounted for the phenom- ena on the theory that the bed had been thrown into a series of parallel and closely compressed and overturned folds, the crests of which had been subsequently denuded (see p. 488). Although on his map a section of the Ocoee conglomerate was put down as belonging at the top of the Azoic series, in his chapter on the Potsdam group it was stated that the Ocoee conglomerate and slates, Chilhowee sandstones, and Knox group of shales, dolomites, and lime- stones might be regarded as a formation which corresponds to Dana's Potsdam period, and that it was not easy to separate, lithologically, the Ocoee subgroup from the Chilhowee, as they often run into each other. The main bulk of the report was given up to a discussion of the distribution, lithological nature, and characteristic fossils of the var
