In topography a considerable amount of work has been done 

 by the survey, especially in the western portion of the State, 

 since no topogra[)hical survey of that region had been made, and 

 a more accurate map was needed as a base for the geological 

 map. The necessary preliminary work was undertaken by the 

 Geological Survey, and was carried on by Professor Kerr and 

 his assistants at intervals, along with the field work in geology. 

 Much of the topographical work was done somewhat hurriedly, 

 but with as much detail and care as circumstances would permit, 

 with the use of the pocket compass, pocket level, aneroid or 

 mercurial barometers, pocket or marine sextant and chronometer 

 (for obtaining latitude and longitude where necessary). A map 

 of the State, embodying the results of many of these observa- 

 tions, together with data compiled from various other surveys, 

 was published in 1882. 



In general geology the work has been done by Professor Kerr 

 in person. All the geological formations within the State have 

 been examined, their outlines and general characters as to lithol- 

 ogy, soils, topography, etc., noted. In this department, how- 

 ever, much detail work still remains to be done in all parts of 

 the State. 



In lithology the collections of crystalline and metamorphic 

 rocks were submitted to Professor A. A. Julien (who has several 

 times visited the region in person) for microscopic examination. 

 His report is now in preparation. 



In mineralogy the collections were in most of the cases sub- 

 mitted to Dr. F. A. Genth, whose reports are to be found in 

 Kerr's Geology of North Carolina, Vol. I, 1875, Appendix 

 C, and Vol. II, Chaf). I, 1881. 



In vertel)rate and invertebrate })ale()ntology the collections of 

 the survey were submitted to Professors E. D. Coi)e and T. A. 

 Conrad, respectively, both of wljom, without remuneration, twice 

 visited the State for the purj)ose of examining specimens and 

 making collections. Their reports are to be found in Kerr's 

 Geology of North Carolina, 1875, Appendix A.
