lent falL This fog occafions almoft perpc- 

 tual rain here, which is more or lefs heavy, 

 in proportion to its diftance from the fall. 

 Mr. Gaulthier and myfelf, together with 

 the man who fhewed us the way, were wil- 

 ling to come nearer to the falling water, in 

 order to examine more accurately how it 

 came down from fuch a height, and how 

 the ftone behiad the water looked. But, 

 being about twelve yards off the fall, a 

 fudden guft of wind blew a thick fog upon 

 us, which, in lefs than a minute, had wet 

 us as thoroughly as if we had walked for 

 half an hour in a heavy (hower. We there- 

 fore hurried away as faft as we could, and 

 were glad to get off. The noife of the fall 

 is fometimes heard at ^ebec, which is two 

 French miles off to the fouthward ; and this 

 is a iign of a north-eaft wind. At other 

 times, it can be well heard in the villages, a 

 good way lower to the north ; and it is then 

 reckoned an undoubted fign of a fouth-weft 

 wind, or of rain. The black lime-flate on 

 the fides of the fall lies in dipping, and al- 

 moft perpendicular ftrata. In thefe lime- 

 ilate ftrata, are the following kinds of ftone 

 to be met with.
