Persoiiiicl. — During tlic 10 year.s from 1S78 to 1882, inclusive, Dr. 

 K. A. Smith devoted tlie greater part of the tliree months of each 

 summer vacation to geological excursions, receiving, however, no 

 compensation in th.e way of salary, the cost of traveling and sub- 

 sistence being paid, together with other contingent expenses, out of 

 (he appropriation of $500. During th.e siinnners of 1878 to 1882, 

 Henry McCalley, assistant in tlie chemical department of the uni- 

 versity, served as a volunteer assistant in the field, his actual ex- 

 penses only being paid. Prof. W. C. Stu1)bs also voluntarily as- 

 sisted in making chemical analyses, and T. H. Aldrich in prepar- 

 ing a sketch of the early coal-mining industry in the State. Thi< 

 was published in the report for 1875. 



Pi/?jIicat/G/is. — During this period of 10 years tliere were pub- 

 lished four annual reports, namely, for 187^3, 1874, 1875, and 1876. 

 and three biennial reports, namely, for 1877-78, 1879-80, and 1881-82. 



With the exception of that upon agriculture (1881-82) these were 

 of the nature of preliminary or reconnoissance reports, and dealt 

 chiefly with the economic features of the State. The report for 187o 

 Nvas simply a statement of the plan of the work proposed. That of 

 1874 was concerned with the crystalline region, and particularly with 

 the copper-bearing strata. At the time when the examinations w^ere 

 made there, the whole section was greatly interested in the subject 

 of copper, just as it has since become in gold. The next report (1875) 

 treated of the same subject, but the greater part of it Avas devoted to 

 the examination and classification of the formatioiis of Jones 

 \":dley and the great Coosa Valle}' region. Professor Tuomey had 

 recognized the occurrence in these valleys of the Silurian, Devonian, 

 and Subcarboniferous formations, without undertaking the subdi- 

 vision of the same, except in the case of the Clinton and Trenton. 

 During the summer of 1875 Doctor Smith established the practical 

 identity of these fornuitions with what had already been so clearly 

 described in Tennessee by Professor Safford, and also the fact of 

 the existence in Alabama of the Ocoee, Chilhowee, Knox Sandstone, 

 Sliale, and Dolomite, the Lower and Upper Subcarboniferous with 

 their respective minor divisions. The report for 1875 contained also 

 Mr. Aldrich's sketch of the early history of coal mining in Alabama, 

 to which reference has been made al)ove: and there were also pre- 

 sented the records of the borings by diamond drill in the different
