period of five years, to carry out the purposes of this act, and this appropria- 

 tion shall take effect annually, commencing on July 1, 1890. 



Sec, XI. Be it further enacted, That all laws in conflict with this act are 

 hereby repealed. 



Approved, November 12, 1889. 



Administration. — Under this law J. W. Spencer was appointed 

 State geologist, entering upon his duties July 1, 1890. C. C. Ander- 

 son, a civil engineer, was put in charge of the hydrographic work of 

 the survey and E. T. Whatley appointed assistant geologist, the as- 

 sistants being appointed, according to the text of the law, by the 

 governing board. 



The salary of the State geologist was fixed at $2,500 a year and 

 that of his assistants at $1,250 a year. Doctor Spencer remained 

 in office until 1893, when he was succeeded by W. S. Yeates,* under 

 whom the following have from time to time served as assistants: 

 F. P. King, S. W. McCallie, George E. Ladd, Thos. L. Watson, as 

 geologists; R. L. Packard and Walter L. Mitchell, chemists, the 

 salary remaining as under Doctor Spencer. 



Prthlications. — During Doctor Spencer's administration two re- 

 ports were published, one termed Administrative, but devoted 

 quite largely to the geology of the Cretaceous and Tertiary forma- 

 tions of the southwestern part of the State; and the other issued 

 under date of July 1, 1891, entitled The Paleozoic Group, compris- 

 ing some 400 pages and including the geology of 10 counties of the 

 northwestern portion of the State and their economical resources. 



Museum, — A very satisfactory exhibit of the mineral and economic 

 products of the State has been built up and is now on display at the 

 statehouse. 



Expenses. — ^The expense of the survey, aside from cost of publica- 

 tion, would appear to have been fully met by the appropriation 

 authorized in the bill of November 12, 1889— $8,000 a year for the 

 ensuing seven years (1889-1896), and $10,000 a year since that date. 

 The average cost of publication of the bulletins is given as $3 a page 

 with 22^ cents additional a volume for cloth bindings. At present 

 the cost of publication is met by an annual appropriation of $2,500.
