32 SAND DUNE REGION OF SAGINAW BAY. 



including archeology, are those of Schoolcraft, Miles, Lane, Davis, 

 Thomas, and Smith. 



In 1820, Schoolcraft (1855) traversed this coast from Pointe- aux 

 Barc^ues to Oak Point (Point aux Chenes), crossing the bay at this 

 place. He describes briefly the topography and vegetation of the 

 sand ridges (p. 54). 



In 1859, Dr. Manly Miles (1861, pp. 22-23) ''who had beeil designated 

 to take special charge of the department of zoology [^lichigan Geolo- 

 gical Survey] descended the Saginaw River to its mouth, in company 

 with a young man who was subsequently employed during the season 

 as taxidermist and general assistant." Although the region explored 

 by Miles on this trip is far removed from the area worked by us, it is 

 necessary to call attention to this expedition for many of the records, 

 published in the lists after the work of the following year on the coast 

 farther eastward, are given as "\dcinity of Saginaw Bay" or "Saginaw 

 Bay" so there is no way of determining just where the species was 

 observed. 



In 1860, A. Winchell, Miles, White, and N. H. ^Yinchell (botanical 

 assistant) explored "the whole coast from the mouth of the Saginaw 

 River t& the vicinity of White Rock." (1861, p. 27.) In his catalog 

 of the mammals, birds, reptiles and mollusks. of the state. Miles (1861, 

 pp. 219-241) gives a few foot-note references to the occurrence of certain 

 species of animals taken "near Saginaw Bay." As said above, it is 

 impossible in many instances to determine which of these records 

 apply to the sand region, and similarly general locality records' are 

 given in the list of plants of lower Michigan compiled by N. H. 

 Winchell in the same report (1861, p. 247, et seq.), but a supple- 

 mentary list of the plants of Stony (Stone) Island is also given 

 (p. 328). 



By far the best and, in fact, the only good report on the physical 

 conditions and biology of the region is to be found in Lane's (1900) 

 ''Geological Report on Huron County, Michigan." In this report 

 the sand region topography is described in detail, and the climate 

 discussed. There is also a discussion of the flora by C. A. Davis with 

 lists of the plants observed by him in the county. In this list exact 

 localities and habitats are given as a rule, so that the paper has 

 been of particular value to us in our work on the flora of the sand 

 region. 



Some of the records secured by this expedition have been published 

 elsewhere (Ruthven, 1909 and 1910). 



The archeology of this part of Huron County is referred to by several 

 writers. Thomas (1891, pp. 109-110) states that there is a "large 

 circular work in Case\'ille Township on a small stream emptying into
