During the remaining months of the survey's existence the energies 

 of nearly all were concentrated on practical problems, those se- 

 lected as most essential being the study of the Oconto iron district, 

 the completion of the survey of the Penokee iron range, and a con- 

 tinuation of the so-called crevice survey of the lead region. Irving 

 brought to completion his final report on the eastern portion of Lake 

 Superior. Chamberlin, in company with A. D. Conover, made a 

 reconnoissance of Polk and Burnett counties, with particular refer- 

 ence to the drift deposits. Brooks continued and brought to com- 

 pletion his work in the Menomonee iron region. 



Expenses. — The act establishing the survey limited the expenses 

 to $13,000 a year for four years. The act of November 20, 1878, 

 extended the time for two years with appropriation of $5,000 a year. 

 This would bring the total cost of the survey, exclusive of publica- 

 tions, up to $62,000. The cost of the latter, by the act of March 6, 

 1876, was limited to a sum not exceeding $25,000. 



Collections and museum. — In accordance with section 3 of the or- 

 ganic law of the survey, large collections of fossils, ores, rocks, and 

 minerals were made, one set of which was deposited with the Wis- 

 consin Academy of Sciences, Arts, and Letters, one with the State 

 University, and one each to such of the incorporated colleges and 

 normal schools as should make application for them before the be- 

 ginning of the field work. Some 20,000 specimens are reported to 

 have been thus destributed during 1879, the closing j^ear of the 

 survey. These were largely in the nature of fossils, the ores and 

 lithological materials being reserved for future study. 



The following acts relate to the publication and distribution of 

 the reports:
