456 THE CANADIAN NATURALIST. [Yol. X. 



It was reported from Ottawa, Perth and many other places in 

 Ontario, east of a line joining Kingston and Pembroke ; from 

 Cornwall, Montreal and other places in the St. Lawrence Valley, 

 as far east as Three Rivers; from Hanover, N. H., Springfield, 

 Mass., Hartford, Conn., and other places along the Connecticut 

 River; from Burlington and Bennington, Vt. ; from Plattsburg, 

 Whitehall, Saratoga, and the valley of Lake Champlain and 

 the Hudson, as far south as Albany, N. Y. ; and finally from 

 Utica, Rome, Auburn and the Mohawk Valley. It would thus 

 seem to have been felt over an irregular trapezium, whose angles 

 are marked by Pembroke, Ont., Three Rivers, Que., Hartford, 

 Conn., and Auburn, N. Y. ; and which is therefore some 200 miles 

 on its northern and southern sides, about 300 on the east and 

 175 on the west. Comparing the reports of time from thirty-six 

 localities, we find them cluster closely about 2 a.m., none earlier 

 than 1.45, none later than 2.10 — most being between 1.50 and 2, 

 local time. The most accurate appear to be Montreal, 1.50 a.m., 

 Hartford, 1.56=1.52, Montreal time, and Dudley Observatory, 

 Albany, 1.53=1.54, Montreal time. The duration in Montreal 

 was about twenty seconds, and in other places about the same. 

 It seems to have been most severe in the valley of the St. Lawrence 

 and about Lake Champlain, where the vibration was sufficient 

 to overturn crockery, crack ceilings, and, in a few cases, throw 

 down chimneys. The reports were nearly unanimous that the 

 vibration advanced from west to east. In some places a rumb- 

 ling noise, and in others two or several shocks were reported. 



Nov. 14. — At 9.40 a.m. a slight shock occurred at Cornwall, 

 Ont. 



Dec. 18. — At Beachburg, Ont., two shocks occurred, the first 

 between 1 and 2 a.m., the second between 5 and 6 a.m., and 

 quite severe. •

June 11, 12. — A light shock at 10 p.m. was felt at Montreal 

 and east and southeast from there, as far as Waterloo and Fre- 

 lio-hsburo;. At Montreal it was described as " loud rumblinor, 

 slight shock and continuation of rumbling." The direction was 

 said to be N. to S. Some persons reported a second light shock 

 and rumbling at 2 a.m. on the 12th. 



Aug. 21. — The country between Lakes Erie and Ontario was 

 severely shaken about 3 a.m. The earthquake was reported from
