 Cassina Lake was determined to be in 47^ 

 38^ N. Lat. Descending the Mississippi to 

 the mouth of the Ouisconsin, a distance of 

 one thousand miles, they ascended the lat- 

 ter river to a small portage of one mile, 

 which brought them to Fox river, emptying 

 into Green Bay. During the rainy season 

 canoes are enabled to pass from one river 

 to another, thus rendering the navigation 

 complete. The expedition here separated 

 into two parties, one of which proceeded 

 along the shores of Green Bay to Makinaw, 

 whilst the other coasted along the southern 

 and eastern shores of Lake Michigan, which 

 was carefully examined and explored. The 

 parties united at Makinaw, and returned 

 through Lakes Huron and Erie to Detroit ; 

 having thus performed a difficult and fa- 

 tiguing journey of four thousand miles. 

 Numerous observations on Geology and 

 Zoology are scattered through the work, and 

 the notices of the various Indian tribes bear
