the eruption continued the whole night with flames. 

 The certain approach of the earthquake is known when, 

 by the passage between the mountains, you see a cloud, 

 or smoke, quiet or agitated, and on the left and right the 

 horizon is perfectly clear. 



'A fall of ashes covering the snow in 1791 was also 

 within the recollection of many of the inhabitants of 

 St. Paul's Bay.' '.-.'.['

 country north of Tadousac, and is recorded by him in a letter dated June 2, 

 1672. The Pere says that it was the continuation of the terrible earthquake 

 of 1662, ' which has not since ceased in this quarter of the north, although 

 it is felt but little and at intervals.'- Relation de la NouvcUe France en 

 VAnnec 1672. 



f The greatest fluctuations in the Canadian Lakes, during ten years' 

 observations, are found to be in Lake Ontario, where between the low water 

 of 1857 and the high water of 1858 there was a range of 4-5 feet. The 

 observations of Professor Dewey, of Rochester, extending as far back as 

 1846, show this to be the maximum range during the whole period. 

 Colonel "Whittlesey states the extreme range of Lake Erie, as observed, to 

 be 5-25 feet, and Mr. Lapliam's observations at Milwaukee give for the 

 extreme range of Lake Michigan 5 - 5 feet. 



The survey of these great lakes, conducted by Captain G. G. Meade, 

 United States Topographical Engineer, has produced the following results:
