GEOLOGICAL AND NATURAL HISTORY SURVEYS. 465 



ville. He was continued in office under biennial appointments until 

 1848 when the survey was discontinued. While in office he made 

 nine reports, the first two of which do not appear to have been 

 published. It is possible that he considered a discourse delivered in 

 1831, prior to the passage of the act creating the office, as his first 

 report. The second report appears to have been made, judging from 

 certain references to it in the legislative proceedings, on the coal 

 measures of the State. The remaining seven reports, octavo pam- 

 phlets, have long been out of print and are rarely met with. 



The third report, published in 1835 (32 pages), treats of the coal 

 and coal formation with a fair map of the coal area of the State, 

 the greensand of west Tennessee, followed by dissertations on marl, 

 humus, and soils, and closes with remarks on iron ores and a list of 

 furnaces then existing in middle Tennessee. 



The fourth report, 1837 (37 pages), has i-^O of its pages devoted 

 to a general exposition of geology as then understood by the author. 

 The latter part is an account of an excursion made by him through 

 what was then known as the Ocoee district of Tennessee — a part 

 of the State lying south of the Hiwassee River and east of the 

 Tennessee. Accompanying is a geographical map of the Ocoee dis- 

 trict, on which is a rude section of the rocks traversed. In the latter 

 the Carboniferous formations are made unconformable with all else 

 in east Tennessee. Closing the report is a list of fossils observed by 

 the author in the State. 



The fifth report, 1839 (75 pages), is the largest of all. It contains 

 first a general view of the geology of the State, wnth a map and sec- 

 tion, in which, by the way, not only the Carboniferous rocks, but the 

 formations of middle Tennessee, are treated as if unconformable with 

 the inclined strata of east Tennessee. Then follow descriptions of 

 Cocke County, its formations, iron ores, and of a meteorite found 

 within the limits of the county. To this succeed brief notices of 

 other iron ores, of furnaces, a supposed silver ore, and certain 

 mineral waters. The last 30 pages are an annotated catalogue of the 

 fossils found in the State. 



The sixth report, 1841 (48 pages), begins with a review of former 

 descriptions of the formations of the State, in which also the ap- 

 plication of the names Cambrian and Silurian to Tennessee forma- 

 tions is discussed. Then follow lists of fossils, with notes upon 

 certain species, a notice of Sevier County, roofing slates, alum, epsom 

 salts, nitre, iron ore, and certain mineral waters. 



The seventh report, 1843 (45 pages), gives first a description of 

 the formations of Xashville and Davidson County, with a list of 

 minerals found at Nashville and notes on certain fossils, followed 

 by remarks upon the formations of middle Tennessee in general, also
