The appropriation for the maintenance of the survey was too 

 small to admit of a separate survey being made. During almost the 

 entire period of the existence of the survey, Professor Kerr, in mak- 

 ing his excursions over the State, was, therefore, obliged to combine 

 topographical and geological work, and this greatly retarded the 

 geological work. 



Again, the correspondence of the survey made a continuous de- 

 mand upon the time of the geologist — a demand of more importance 

 than can be realized by those unfamiliar with the facts in the case. 

 This correspondence w^as undertaken by the geologist in person and 

 often retarded in no small degree the progress of liis work in other 

 directions. 



During the years 1873, 1876, and 1881, a considerable poition of 

 the work of the survey was given to the making of collective ex- 

 hibits, illustrative of the State's resources, at the Vienna, Centennial, 

 and Atlanta expositions, respectively. Indeed, so great was the 

 variety of work expected and demanded of the survey in connection 

 with the economic resources of the State, that the amount of purely 

 scientific work accomplished was thereby greatly limited. 



Personnel. — The personnel of the survey for each fiscal year ending 

 September 30 is given below. This list is believed to include the name 

 of every individual w^ho has been engaged upon the work. There 

 were no regular or permanent assistants connected with the survey. 

 Assistants were engaged from time to time by the geologist for spe- 

 cial professional work or general office work as tliey were needed or 

 could be secured. Some of these had only a nominal connection, 

 others were connected with it at intervals during several years.
