Dr. U. S. Grant read a paper on Minnesota Lakes having 

 more than one Outlet. 



[abstract.] 



Among the numerous lakes in the northeastern portion of the state 

 are several which have two outlets each. Such are: Brul6 Lake in 

 Cook County; a small lake on the International boundary between Gun- 

 Hint and Saganaga lakes in Cook County; three lakes along the Kaw- 

 ishiwi river in Lake County; Iron Lake, Lac la Croix, and Namekan 

 lake on the International boundary on the northern edge of St. Louis 

 County. The origin of two outlets in a lake of this class is due to in- 

 equalities of drift deposition such that a basin is left with two depres- 

 sions of about equal altitude in its rim. In case of at least one of the 

 larger lakes, — Brule lake, — it is possible that the western outlet is of 

 quite recent date and is due to the westward canting of the basin by the 

 general tilting which has been taking place in the Great Lake region 

 since near the end of Glacial time.

 ipp. 407-411, June, 1897, under the title "Lakes With Two Outlets in 

 Northeastern Minnesota.")
