An act for a geological and mineraloglcal survey of the State of Illinois. 



Skction 1. Be if enacted hy the people of the State of lUinois, represented in 

 the General Assembly, That the governor, auditor, and treasurer of the State 

 are hereby authorized and required, as early as may be, to employ a geologist 

 of known integrity and practical skill for the purpose of making a geological 

 and minerological survey of the entire territory of this State. 



2. It shall be the duty of said geologist to proceed, as soon as the neces- 

 sary arrangements can be made, and with as much despatch as may be consist- 

 ent with minuteness and accuracy, to ascertain the order, succession, arrange- 

 ment, relative position, dip, and comparative magnitude of the several strata 

 or geological formation within the State; to search for and examine all the beds 

 and deposits of ores, coals, clays, marls, rocks, and such other mineral sub- 

 stances as may present themselves, and to obtain chemical analysis of these 

 eubstauces, the elements of which are undetermined; and, by strict barometrical 

 observations, to determine the relative elevations and depressions of the differ- 

 ent parts of the State. 



3. It shall also be the duty of said geologist, during the time employed in the 

 above work, to make annual reports of the progress and results of his labor, 

 accompanied by such maps and drawings as may be deemed necessary to illus- 

 trate the said reports; all of which shall be transmitted to the governor, in 

 such condition as he may, without delay, cause them to be printed and circu- 

 lated throughout the State or wherever else he may desire to send them. 



4. It shall be the duty of said geologist to procure and preserve a full and 

 entire suite of the different specimens found in the State, and cause them to be 

 delivered to the secretary of state, who shall cause them to be properly ar- 

 ranged in a cabinet, and deposited in some apartment in or convenient to the 

 capitol. Said suite shall be sufficienly large to furnish specimens to all institu- 

 tions of learning within the State, empowered to confer degrees in the arts and 

 sciences. 



5. The final reports of said geologist shall embody the results of the entire 

 survey, and shall be accompanied by a geological map of the State, showing, by 

 different colors and other marks and characters, the precise localities and extent 

 of the different geological formations. 



G. For the purpose of carrying out and completing the said survey the sum of 

 not exceeding $3,000 is hereby placed Jit the disposal of the governor, to be ap- 

 plied to the payment of the said geologist, and such assistants as he may employ, 

 by and with the consent of the governor, auditor, and treasurer, and to defray 

 the incidental expenses of the survey; which annual appropriation shall con- 

 tinue until the completion of said survey, or until its discontinuance be ordered 

 by the legislature of this State. 



7. No money shall be paid to said geologist or for the purpose of said survey 

 until the work shall be commenced. 



8. The said survey shall, if practicable, be commenced at the southern part 

 of the State and be proceeded with northerly. 



This act to take effect and be in force from and after its passage. 

 Approved, February 17, 1S51. 



In 1853, and again in 1872, this law was supplemented and amended 

 by the passage of the following: 



That the sum of $5,000 be, and the same is, hereby annually appropriated for 

 the purpose of carrying out and completing the geological and minera logical 

 survey of the State of Illinois; and also the further sum of $.500 per annum,
