GEORGIA GEOLOGICAL SURVEY 173 



liminary report of his reconnaissance, published the same year. The 

 supplementary and final report of Hilgard's reconnaissance was published 

 in 1872, by which time three reports had been issued by Doctor Hopkins, 

 of the Louisiana Survey. In these Hilgard found many confirmations 

 of his conclusions and many observations supplementary to his own. 



Of the excellent work of Lerch, Clendenin, Gilbert Harris, and his 

 associates in Louisiana geology, only bare mention can be made in this 

 address. 



Hilgard left the University of Mississippi for the University of Mich- 

 igan in 1873, and after two years' service there he was called to the Uni- 

 versity of California as Professor of Agricultural Chemistry and Director 

 of the California Experiment Station (the first to be established in the 

 United States) and Dean of the Faculty of Instruction in Agriculture. 



His continued agitation for agricultural instruction in the public 

 schools of California and the popularization of rational agriculture, to- 

 gether with the broad instruction personally imparted, have given him 

 an extraordinary popularity in that state, just as his 1860 report has 

 done for him in Mississippi. Witness the beautiful Hilgard avenue in 

 Berkeley. 



His achievements in soil investigations, and particularly his work on 

 arid countries and soils, which brought him a gold medal from the 

 Munich Academy, a semi-centennial diploma from the University of 

 Heidelberg, and a world-wide fame, while carried out mainly in Cali- 

 fornia, should at least be referred to here, as they are the logical outcome 

 of researches begun in Mississippi. 



GEORGIA 



During the first three decades of the last century the most important 

 notes on the geology of Georgia are to be found in the writings of Bar- 

 tram, Maclure, Cornelius, Morton, and Shepard. The first attempt at a 

 systematic study of it was made in 1836 by the establishment of a State 

 Geological Survey and the appointment of Mr. John E. Cotting as State 

 Geologist. He had previously made investigations and a report on the 

 counties of Burke and Eichmond at the expense of those counties, and it 

 was because of these reports that Governor Schley recommended to the 

 state legislature the action above mentioned. 



Mr. Cotting's first report as State Geologist was submitted to the legis- 

 lature in 1837. Though recommended to be printed by the proper com- 

 mittee, this report was never published and the Survey was abolished in 

 1840.
