Severe shocks at St. Paul's Bay. 



A violent shock. 



A severe shock at Montreal. 



A second shock, less violent. 



Felt near Quebec. 



At St. Andrew's. 



At Montreal, slight, followed by an 



awful storm, with rain impregnated 



with matter like soot. 

 At Quebec, a slight shock. 

 On shore of Lake Erie.

Montreal. 



'First. That the lakes are sensibly and rapidly affected by winds and 

 storms, depressing the water on the side from which the wind blows, and 

 raising it on the opposite side. (In November 18-59 the ranges due to 

 winds in Lake Erie amounted to 5-59 feet at Monroe, and to 6-20 feet at 

 Buffalo.) 



' Second. That independently of the wind fluctuations, the lakes are 

 subjected to changes of level, due to the relative proportions of their supply 

 and discharges the supply arising from rains and drainage of the water- 

 sheds the discharges arising from evaporation and the flow through their 

 outlets. 



1 Thirdly. That, as a general rule, these last fluctuations occur annually, 

 there being a high and low stage every year the former in summer, the 

 latter in winter and that within small limits of time these annual changes 

 are very nearly simultaneous. 



' Fourthly. That these annual fluctuations, both the high and the low 

 stages, vary in degree from year to year, they being the effects of variable 

 causes, and that the extreme ranges, as yet reported between the highest 

 and lowest waters, has amounted to 5 - 5 feet in other words, the above 

 phenomena are those of a great river flowing through extensive reservoirs, 

 which receive and absorb the freshets, and thus modify, both in degree and 

 time of occurrence, the ordinary fluctuations.'
