Kaiuy Eiver: 



Island 4 miles above the Manitou Rapids S. 38° W. 



One mile below the Long Sault, and at thu first and second rapids of Pino River, three 



localities, alike S. 24° W. 



One mile above the month of Rapid Eiver S. 38° W. 



Around the Lake of the Woods, observations in about 180 localities by Dr. A. C. Lawsoc 

 and assistants, and in about 60 localities reported by Dr. G. M. Dawson, "the great 



majority," i. e. 82 per cent, are S. 35°-55° W. 



But 13 per cent are S. 10° -34° W. 



And 5 per cent are S. 56°-83° W. 



Only four localities showed courses more westerly than S. 65° W. ; one of these is on the 



southeast side of Big Island, where strito bearing S. 75° W. 



Intersect others bearing S. 37° W. 



On the west side of Bigsby Island, which, like the preceding, lies near the middle of Sand 

 Hill Lake (the southern and largest part of the Lake of the Woods), douljle sets of 



stria) were observed in two places, respectively N. 80^ W. and S. 20- W. 



And N. 83° W. and S. 33° W. 



And on a joint projecting from the south shore in the southwestern part of this Sand Hill 



Lake, atvUe. bear S. 70° and 65° W. 



With others S. 35° and 33° W. ; also, S. 10° E. 



[Probably the bearings S. 10° E. to S. 20° or 30° W. belong to the time of the 

 maximum depth and area of the ice-sheet; the ijrevailiug southwestern courses, to 

 later glaciation: and the more westerly deflections, to the time of final melting 

 of the ice.]
