66 LAKE SUPERIOR. 



came in the way, was reminded of the impropriety by a dig from the 

 end of it at every stroke, until he withdrew within his proper limits. 

 About these matters, (which, however, were confined entirely to the 

 management of the boat, &c., and respected exclusively the public 

 interests,) they never argued nor attended to arguments, but quietly 

 persisted in doing as they thought proper. 



The immediate shore on our course this afternoon, was lower than 

 we had had it since leaving Gros-Cap ; rounded, gradual slopes of 

 rock down to the water, bare in some places, and the rest covered 

 with a scanty growth of trees. At some distance back, rounded hills 

 rose to a greater height. 



We were struck here and elsewhere by the regular succession of 

 coves and points, owing apparently to the trap-dykes, which, in-^tead 

 of being more easily decomposed than the surrounding rock, and thus 

 forming chasms, as on the other side of the bay, were here harder, 

 and so stood out from the rest.* 



At several places we observed terraces, and carried two of them, 

 at various heights, but preserving their relative positions, about two 

 miles, to the Riv. a la Chienne, where they turned up the valley and 

 extended along its left bank as far as we could see, having an eleva- 

 tion of about two hundred feet. Here, according to intention, we 

 encamped at sunset, fifteen miles from our starting place. This 

 river is deep, and about ten fathoms wide, umber-colored as usual, 

 with a broad expansion inside, which, with the wideness of the 

 valley and the scanty growth on the terraces (doubtless of sand) 

 forming its left bank, permitted an extensive view up the stream 

 into an amphitheatre of high rounded hills, behind which the sun was 

 setting. There are rapids and a fall of about ten feet a quarter of 

 a mile up. We pitched our tents on a spit of sand, broad at the base, 

 and running out in a point across the mouth of the stream to witliin 

 a few yards of the steep rock of the right bank. Just inside the 

 point, the bottom sunk sheer down twenty feet. Outside there is 

 a bar, having only a few feet of water on it. 



One of the men collecting firewood on the bank found a bear's 



* This contrast between the different dykes induced the Professor to examine into 

 their relative ages, and thus led to the views set forth in the paper on the Outlines of 

 the Lake.
