6 GEOLOGICAL SURVEY OP WISCONSIN. 



2d. Accurate chemical analyses and assays of the various ores, clays, peats, marls, 

 building stones, etc., discovered by the state. 



3d. A careful topographical survey of the lead region, for the purpose of ascertaining 

 as far as possible, the amount of denudation, and the exact position of the mining 

 ground at each locality; also careful barometrical observations on the relative elevation 

 and depression of various parts of the state. 



4th. An examination of soils and subsoils, and observations upon the animal and vege- 

 table productions of the state, with reference to its agricultural interests. 



SECTION 3. It shall be the duty of said geological corps, in the progress of the ex- 

 aminations hereby directed, to collect such specimens of rocks, ores, fossils, minerals, etc., 

 as may be necessary to exemplify the geology of the state. Sets of these specimens shall 

 be deposited with the "Wisconsin Academy of Sciences, Arts and Letters, and the State 

 University, and with each one of the incorporated colleges of the state, and with each 

 of the normal schools : provided, application be made to the chief geologist before the 

 commencement of field work. 



SECTION 4. It shall be the duty of the chief geologist and his assistants, on or before 

 the first Monday in January in each year during the continuation of the survey, to mako 

 to the governor a report of the progress and results of the survey, accompanied by such 

 maps, profiles and drawings as may be necessary to exemplify the same, which reports 

 the governor shall lay before the legislature. 



SECTION 5. As soon as the progress of the survey will permit, the chief geologist shall 

 begin, and on completion of the survey, shall complete a final report, including the re- 

 sults of the entire survey, accompanied by such drawings and topographical maps as 

 may be necessary to illustrate the same, and by a single geographical map showing by 

 colors and other appropriate means the stratification of rocks, the localities of the beds 

 of mineral deposits, and the character and extent of the different formations. 



SECTION 6. To carry into effect the provisions of this act, the sum of thirteen thou- 

 sand dollars for each year, until the completion of said survey, is hereby appropriated 

 to be drawn from the treasury on wa.rrants from the governor, as needed; which shall 

 be in full for all expenditures except printing of reports. The salary of the chief geolo- 

 gist, and the salaries of the assistant geologists shall be fixed by the governor, and shall 

 be for services actually performed, and time actually spent in the work. The balanco 

 of the sum hereinbefore appropriated shall be used in such manner as shall best pro- 

 mote the purposes of this act. 



SECTION 7. The survey shall commence by the first of June next, or as soon thereaf- 

 ter as practicable, beginning with the counties of Ashland and Douglas, and the entire 

 survey shall be completed within four years from and after its commencement. 



Approved March 19, 1873.
