Two later earthquakes are reeorded by Sir William 

 as Laving affected the Maritime Provinces.^ These 

 are said to liave been powerful enoiio-h to shatter Avails, 

 thi'ow down chimneys, and do other similar damage. 

 Other earthquakes of slight intensity have occurred 

 in this region since 1870, but I have not at hand the 

 record of the time of their occurrence, or the areas afiected 

 by the shocks. 



As collateral to this subject 1 may mention the exist, 

 ence of two objects in the museum of the Xatural History 

 Society of ISTew Brunswick which appear to show earth- 

 movements since the glacial period : One is a glaciated 

 boulder from the Grand Falls of the St. John river, 

 collected and presented by R. Chalmers, that since its 

 entombment in the boulders clay has been broken apart, 

 the pieces somewhat displaced and then re-cemented. 

 The other, which indicates more recent fracture, is a 

 stone lance-head offelsitic material found at Grand Lake, 

 which, since it was originally lost in the debris of a camp 

 site of the stone age, was broken apart, the pieces slightly 

 displaced, and tlie lance-head again cemented so as to 

 be as perfect as before, except for the line of the crack 

 and the slight displacement where the pieces are joined. 



A short notice of these pre-glacial faults has been 

 communicated to the American Journal of Science. It 

 is to ])e hoped that the members of the Society will 

 exannnc the surfaces of ledges in other localities to find 

 out wliether the phenomenon of glacial faults is of com- 

 mon occurrence in other parts of the province.
