GEOLOGICAL, AND MATUKAL HISTORY SURVEYS. 191 



portion of the range have been found to be more extensive than was 

 originally supposed." 



He finds the southerly range of mountains before referred to, be- 

 ginning near the mouth of the Chocolate River, to be continued across 

 the Menominee River into Wisconsin. " AVithin the limit of this 

 range would fall the lead district of Wisconsin and Iowa"; but he 

 gives reasons for thinking no lieavy deposits of lead will be found in 

 Michigan. 



He remarks that the " field work of the geological and topographi- 

 cal surveys upon the plan originally contemplated, is now mainly 

 completed"; iDut a large amount of laboratory and office work must 

 yet be performed in preparation for a final report. As the funds set 

 apart for tlie survey are now exhausted, and the survey expires by 

 limitations, he asks a small appropriation for the completion of the 

 work. He states that maps of the counties of Hillsdale, Lenawee, 

 Branch, Calhoun, Jackson, and Washtenaw have been engraved, 

 and enumerates 13 others as ready for the engraver. Wayne had been 

 engraved in 1839, and it does not appear why it is not enumerated 

 with the others. Of the $2,000 appropriated March 28, 1840, for 

 the map of the State, $1,500 remained unexpended; T am unable to 

 ascertain whether this became available. 



SIXTH YEAR OF THE SURVEY, 184 2. 



Though no legislation was had perpetuating the survey after the 

 expiration of the four years for which provision was made in 1838, 

 the office of State geologist was not abolished, and I find that $3,700 

 were paid out of the State treasury for salaries of geologist and 

 topographer and for other purposes. It is probable, however, that 

 some portion of this was a balance from the old appropriation. 

 Gov. John S. Barry, in his message to the legislature of 1843, after 

 enumerating the great desirability of geological surve5's, and an- 

 nouncing the substantial completion of the field work though much 

 office work remained, says: 



If the commencement of a geological survey of the State wns now a question 

 presented for consider.ition, I should hnve no hesitation in recommending ita 

 postijonement ; and whilst I think the survey now in progress was prematurely 

 nndertidcen. yet, ns it is so nenrly brought to a close, true economy seems to 

 ••^^quire its completion.* 



The sixth annual report of the State geologist is dated January 

 31, 1843, and fills but four pages. It shows that most of his time 

 during 1842 was occupied in office work. Doctor Houghton writes 

 that the field work for the entire survey is completed, with the ex-
