of Lake Superior. 5 



On the new route to the Lake of the Woods, from Fort William, 

 Major DeJafield* considers the highest water-level to be close to 

 Cold Water Lake, about 50 miles direct from Lake Superior, and 

 in Ion. 90° 14' lat. 48° 59'. Major D. has furnished me with the 

 subjoined details ; which assign to the spot, the height of 505 feet 

 above the surface of the last-named laket. At this place the 

 neighbouring heights are about 200 feet above the small lake or 

 pond ; but at the corresponding point on the old route I found 

 the land in steep woody ridges 400 and 600 feet high, interspersed 

 with frequent precipices of great height and magnitude. 



This height of land, including the tributary smaller lakes and 

 rivers, is never very distant from the lake ; and the remark may 

 be extended to the lower lakes, Huron, %c. Making use of the 

 best map of the vicinity of Lake Superior, that of Major Long J, the 

 sources of all the rivers on the south shore, are within 60 miles, 

 measured in a straight line. Although the whole of this region is 



* A^ent for the United States, under the sixth and seventh articles of the 

 Treaty of Ghent.

These estimates are entirely conjectural, being founded on no other obser- 

 vations than those of the eye; their coincidence, however, with similar ob- 

 servations by others of the party, made at different times, render it probable 

 that they do not differ materially from the truth.
