NARRATIVE OF THE EXPEDITION. 125 



Lake, we passed six small rapids, at distances of three, four, three, 

 one, five, and eleven miles, where the river sinks its level twenty- 

 nine feet, in the estimated aggregate distance of seven hundred 

 yards.* Above the latter, extending twenty miles, to the point 

 of our encampment, there is no perceptible rapid. It was eight 

 o'clock when we encamped, having been eleven hours in our 

 canoes, without stretching our legs, and we had ascended forty- 

 six miles.
