A NATURAL HISTORY SURVEY OF MICHIGAN* 

 In Michigan, as in many other States, the 

 desirability, or, perhaps better, the necessity 

 of a survey of the natural resources of the 

 State was early recognized. In 1837 Gov- 

 ernor Mason approved an act providing for 

 a geological, zoological, botanical and topo- 

 graphical survey. 



It is of interest to note that the early sur- 

 veys, or explorations, that followed were 

 not limited to a study of the mineral wealth 

 of the Territory. The flora of the regions 

 visited occupied no inconsiderable part of 

 the time and attention of the explorers, and 

 Dr. Houghton's plants in the University 

 herbarium are, many of them, after the 

 lapse of over half a century, still among the 

 finest in the collection. Economical con- 

 siderations, however, soon led (1840) to the 

 repeal of those portions of the act that per- 

 tained to zoology and botany, and but little 

 more was undertaken in this direction until 

 the survey of 1859 and 1860, the report of 

 which, transmitted by Professor Winchell, 

 in 1860, included Geology, Zoology and 

 Botany, the zoological part consisting of an 

 enumeration of birds, reptiles, batrachians 

 and mollusks, while the part devoted to 

 botany includes a list of vascular plants, 

 with remarks on distribution and econom- 

 ical relations. 



Since that date the survey has been geo-
