shall appoint one or more assistants, not exceeding in number four, one of whont 

 shall be a skillful analytical cbeuiist and assayer; and the chief geologist and 

 Ills assistants to constitute a geological corps, whose duty it shall be to make 

 a thorough and complete geological, mineralogical and agricultural survey of 

 the State, and topographical surveys of such_portions as may be deemed by 

 the corps to need them for the thorough completion of the work: Provided, 

 That if the appointment of the chief geologist be made during the recess of 

 the senate, such appointment may be confirmed at the next session thereof. 



Skc. 2. The survey shall have for its objects: 



1st. An examination of the geological structure of the State, including the 

 dip, number, magnitude, order and relative position of the various strata : 

 their richiness in minerals, metallic ores, clays, mineral waters, fertilizers, 

 building stones, and other useful materials; the value of such materials for 

 economic purposes, and their accessibility for mining and manufacture. 



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

 marls, building stones, etc., discovered by the State. 



Sd. 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 obseivationH 

 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 vegetable productions of the State with reference to its agricultural in- 

 terests. 



Sec. 8. It shull be the duty of said geological corps, in the progress of the 

 examinations 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 incor- 

 porated colleges of the State, and with each of the normal schools, provided ap- 

 plication be made to the chief geologist before the commencement of field work. 



Skc. 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 make to the governor a repoi't of the progress and results of the 

 survey, accompanied by such maps, profiles, and drawings as may be necessaiy 

 to exemplify the ,same, which reports the governor shall lay before the legis- 

 lature. 



Sec. 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, in- 

 cluding the results 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 stratifi- 

 cation of I'ocks, the localities of the beds of mineral deposits, and the character 

 Hud extent of the different formations. 



Sec. 6. To carry into efi'ect the provisions of this act the sum of $13,000 for 

 each year, until the completion of the said survey, is hereby appropriated, to be 

 drawn from the treasury on warrants from the governor as needed, which 

 shall be in full for all expenditures except printing of reports. The salary of 

 the chief geologist and the salaries of the assistant geologists shall be fi.xed by 

 the governor, and shall be for services actually performed and time actually 

 spent in the work. The balance of the sum hereinbefore appropriated shnll b"* 

 used in such manner as shall best promote the purposes of this act.
