mouly turbid with mud, stirred up by the waves from its shores and bed.^ 

 Low land borders this lake along nearly its whole extent, and the highest 

 points on the shore or visible from it rarely attain an elevation of 50 feet. 



Lakes Manitoba and Wiimipegosis. — Lake Manitoba^ lies about 40 miles 

 west of the south half of Lake Winnipeg; and Lake Wiimipegosis,^ sepa- 

 rated only about 2 miles from the north end of Lake Manitoba, lies mostly 

 40 to 50 miles west of the north half of Lake Winnipeg, but its most 

 northeast part is only 20 miles southwest from that lake. The length of 

 each of these lakes, measured in a straight line, is about 120 miles, trend- 

 ing in parallelism with Lake Winnipeg, from south-southeast to north- 

 northwest; and each of them covers an area of nearly 2,000 square miles. 

 Both are shallow in proportion to their size, and are surrounded by low 

 shores. 



The maximum width of Lake Manitoba, about 28 miles, is at its south 

 end. Near its middle it is narrowed to a strait about a half mile wide and 

 2 miles long. Its northern part is of quite irregular form, and is nearly 

 intersected from the north by a long peninsula. This lake, according to 

 leveling by Mr. H. S. Treheme, is 809 feet above the sea, being thus 

 almost exactly 100 feet higher than Lake Winnipeg, to which it is tributary 

 by the Little Saskatchewan. The country between these lakes and from 

 Lake Manitoba west to Lake Dauphin and to Riding and Duck moinitains 

 is low and approximately level, but has a general westward ascent, aver- 

 aging a few feet per mile. 



The width of Lake Wimiipegosis varies from 5 to 15 miles. Its 

 northern portion is bent to the west and south, terminating in Dawson 

 Bay, so that its length, following this com-se, is nearly 150 miles. Its 

 outlines, moreover, are very irregular, presenting a constantly varying

 signifies muddy, and Xepe water, in Chippewa." — Keating's Narrative of Long's Expedition, Vol. II, 

 p. 77. 



-Meaning the "Narrows or Strait of the Manitou or Great Spirit," as I am informed by letters 

 from Prof. George Bryce and Mr. J. B. Tyrrell. This name was originally pronounced by white inhab- 

 itants nearly as by the Indians, with accents on the initial and final syllables; but during the past 

 ten years or more its almost universal pronunciation in English has been with only one accent, which 

 is laid on the nest to the last syllable. 



^Meaning "Little Winnipeg." — Hind's Narrative of the Canadian Exploring Expeditions, Vol. 

 II, p. 42.
