lakes pent up between that watershed and the departing ice-sheet on the 

 north. Kenogami or Long Lake, north of Lake Superior, having a length 

 of about 54 miles from northeast to southwest and a width mostly between 

 a half mile and 2 miles, forming the head of Kenogami River, tributary 

 to the Albany, occupies the clianiiel of outlet from a glacial lake in the 

 Albany basin, passing southward Ijy Trout Lake and Black Ri^-er to Lake 

 Superior.^ The elevation of Kenogami Lake, according- to the survey 

 of the Canadian Pacific Railway, is 1,032 feet above the sea. Dr. Robert 

 Bell states in a letter that the summit crossed by the Height of Land 

 portage close south of this lake, and leading from it to Black River, is 

 about 70 feet higher, being therefore approximately 1,100 feet above the 

 sea. This portage "is about a half mile long, and is over an accumula- 

 tion of well-rounded bowlders, with gravel and earth filling the interspaces 

 in part; at other parts the bowlders are piled on each other quite naked. 

 The valley between the rocky walls is about half a mile wide. The sur- 

 face is somewhat level, and there is a subordinate valley or depression 

 sweeping around on the west side between the bulk of the accumulation of 

 bowlders and the rocky bluff on that side." The ancient watercourse 

 thus described west of the portage is proljably only a few feet above 

 Kenogami Lake, having- very nearly the same elevation as the di^'ide be- 

 tween the Missinaibi and Michipicoten rivers, some 150 miles distant to the 

 east. Both these low points of the watershed were doubtless occupied by 

 rivers outflowing- from glacial lakes on the north during the recession of 

 the ice-sheet. 



Missinaibi Lake, near tlie head of Missinail^i River, the western branch 

 of the Moose River system, is about 1,020 feet above the sea. This lake 

 "bears south 48° west, is 24 miles long, nearly straight, and varies from 

 a half niile to li miles in width."- Close southwest of Missinailii Lake, in 

 the continuation of this glacial river course, is Crooked Lake, at an eleva- 

 tion of about 1,038 feet. "It is 8J miles long, and averages less than a 

 quarter of a mile in width." Near the head of Crooked Lake, and only 

 a few feet above it, is the Height of Land portage, approximately 1,042
