ON NEW ENGLAND EARTHQUAKES, 19 



Falls. August 8, about lO*" A.M., an earthquake was reported at Boston, Dedham, Cape 

 Cod and Nantucket, but not to the north. 



The beginning of this year, January 1 and February 1, shocks are reported in 

 Nova Scotia ; the first broke the ice on ponds and opened doors, the second 

 occurred at Yarmouth and Sherburne. It is well known that intense cold, as well as in- 

 tense heat, causes cracking and subterranean rumbling, and it is necessary to guard 

 against mistaking the origin of similar results. These shocks should probably be referred 

 to atmospheric agencies. 



May 2.3, a shock was felt at Montreal, followed the next day by a torrent of rain. 



September 9, about lO*" P.M., a shock was reported in Rhode Island, Connecticut, New 

 York, New Jersey and Pennsylvania. The Moniteur of September 29, states that a 

 slight shock had just been felt in the northern United States, and this is doubtless the one 

 intended. 



JSfuvemher 6, at S^ 15' A.M., a light shock at Grand Island, in the St. Lawrence. 



December 11, at S*" A.M., a tremor at Montreal.

January 30, at 5"* P.M., a light shock at St. Andrews, Canada. 



January 10, 1852, a shock was noticed at Bedford, Massachusetts, which seems 

 to have extended westward to the Connecticut River. The time given in the 

 reports from New Bedford, Providence, Warwick, was C" 40' A.M. 



February 11, 5'' 40' A.M., at St. Martins, Canada, a light shock from the west-north- 

 west. The barometer stood at 29.067 ; the thermometer at 38.5 F. 



April 30, in the afternoon, a shock was felt in the Eastern States, but principally at 

 Washington and Baltimore.

 ticut River. 



August 1, at Groton, Connecticut. 



August 2, about ll*" P.M., at Bathurst, New Brunswick. 



August 11, P.M., at Deerfield again.

 Newburyport, and through the Valley of the Merrimack, at Beverly, Ipswich, Woburn, 

 Topsfield, Groton, Salem, Danvers and Wareham, Massachusetts, and Portsmouth and 

 Exeter, New Hampshire. At the latter place, the shock lasted half a minute, and shook 

 the houses so as to wake people.^ 



March 12, 1853, between two and three o'clock in the morning, a shock was 

 noticed at Lowville, New York, which threw down machinery. Its direction was 

 east to west, or the reverse, as observers did not agree.^ Felt also in Canada. 



May 24, at Bytown, Canada. 



June 3, two or three shocks at Bridgetown, Nova Scotia.
