286 THE CANADIAN NATURALIST. [Sept. 



during the Dight, and at 7 o'clock 0.21-i of an inch had fallen. 

 Thermometer 42 degrees. Wind S. W. Mean yelocity, 3 . 14 

 miles per hour. 



" At 11 h. 17 m. Montreal mean time, a very considerable 

 shock of an earthquake was felt generally throughout the city ; the 

 first series of vibrations lasted for from 10 to 15 seconds, and was 

 succeeded by a slight interval of a few seconds, when a second 

 shock occurred, of less duration and of less intensity, lasting from 

 5 to 8 seconds. No wave of sound was perceptible, and the wave 

 of motion was undulating and in a straight line (rectilinear) and 

 of considerable relaxation. Domestic articles rocked to and fro, 

 but no damage to buildings has resulted. 



'' The magnets were very seriously affected at 10.30. 



•' The barometer continued to fall after the first shock. At 2 

 p. m. it stood at 29.299 inches ; thermometer 44. 8 degrees ; wind 

 S. Vi., with rain. Professor Kingston telegraphed me that the 

 magnets at the Toronto Observatory showed slight shocks at 10 

 minutes to 11." 



" As usual with Canadian earthquakes, this was felt most 

 severely on the Lower St. Lawrence, .more especially at the junc- 

 tion of the Lower Silurian and Laurentian formations in the 

 vicinity of Bay St. Paul, Murray Bay, and the Saguenay. The 

 following graphic account is given by Rev. Mr. Plamondon, 

 Parish Priest of Bay St. Paul, in a letter to " L\Evenement.''' 



'- Un mot a la hate pour vous faire connaitre les desastres 

 causes, tout a coup ici et dans les environs, par le tremblement 

 de terre le plus etrauge qui soit arrive de memoire d'hommes. 

 Environ une demi-heure avant midi, un coup de foudre (c'est la 

 seule denomination que je puisse lui donner) une enorme detona- 

 tion a jete tout le monde dans la stupeur et la terre s'est mise non 

 a trembler, mais a bouillonner de maniere ii donner le vertige, non- 

 seulement a tons ceux qui etaient dans les maisons, mais encore 

 II ceux qui etaient en plein air. Toutes les habitations semblaient 

 6tre sur un volcan, et la terre se fendillant en cinq ou six endroits, 

 lan^ait des colonnes d'eau a six, huit et peut-etre quinze pieds 

 en Fair, entrainant apres elles une quantite de sable qui s'est 

 etendu sur le sol. Presque toutes les cheminees se sont ecroulees, 

 de sorte que je ne pense pas qu'il en soit reste six debout dans 

 tout le village. Des pans de maisons se sont abattus, et ici et la 

 les poeles, meubles et autres objets out ete reuverses, emportant 

 avec eux les ustensiles, la vaisselle, etc.
